Host Access Class Library Automation Objects

The Host Access Class Library Automation Objects allow the Z and I Emulator for Windows product to support Microsoft COM-based automation technology (formerly known as OLE automation). The ECL Automation Objects are a series of automation servers that allow automation controllers, for example, Microsoft Visual Basic, to programmatically access Z and I Emulator for Windows data and functionality.

An example of this would be sending keys to Z and I Emulator for Windows presentation space. This can be accomplished by manually typing keys in the Z and I Emulator for Windows window, but it can also be automated through the appropriate Z and I Emulator for Windows automation server (autECLPS in this case). Using Visual Basic you can create the autECLPS object and then call the SendKeys method in that object with the string that is to be placed in the presentation space.

In other words, applications that are enabled for controlling the automation protocol (automation controller) can control some Z and I Emulator for Windows operations (automation server). Z and I Emulator for Windows supports Visual Basic Script, which uses ECL Automation objects. Refer to the Z and I Emulator for Windows Macro/Script support for more details.

Z and I Emulator for Windows offers several automation servers to accomplish this. These servers are implemented as real-world, intuitive objects with methods and properties that control Z and I Emulator for Windows operability. Each object begins with autECL, for automation Host Access Class Library. The objects are as follows:

Figure 3 is a graphical representation of the autECL objects:

Figure 3. Host Access Class Library Automation Objects

This chapter describes each object's methods and properties in detail and is intended to cover all potential users of the automation object. Because the most common way to use the object is through a scripting application such as Visual Basic, all examples are shown using a Visual Basic format.

autSystem Class

The autSystem Class provides two utility functions that may be useful for use with some programming languages. See autSystem Class for more information.

autECLConnList Class

autECLConnList contains information about all started connections. Its name in the registry is ZIEWin.autECLConnList.

The autECLConnList object contains a collection of information about connections to a host. Each element of the collection represents a single connection (emulator window). A connection in this list may be in any state (for example, stopped or disconnected). All started connections appear in this list. The list element contains the state of the connection.

An autECLConnList object provides a static snapshot of current connections. The list is not dynamically updated as connections are started and stopped. The Refresh method is automatically called upon construction of the autECLConnList object. If you use the autECLConnList object right after its construction, your list of connections is current. However, you should call the Refresh method in the autECLConnList object before accessing its other methods if some time has passed since its construction to ensure that you have current data. Once you have called Refresh you may begin walking through the collection

Properties

This section describes the properties for the autECLConnList object.

Type Name Attributes
Long Count Read-only

Count

This is the number of connections present in the autECLConnList collection for the last call to the Refresh method. The Count property is a Long data type and is read-only. The following example uses the Count property.

Dim autECLConnList as Object
Dim Num as Long
 
Set autECLConnList = CreateObject("ZIEWin.autECLConnList")

autECLFieldList Class

autECLFieldList performs operations on fields in an emulator presentation space. This object does not stand on its own. It is contained by autECLPS, and can only be accessed through an autECLPS object. autECLPS can stand alone or be contained by autECLSession.

autECLFieldList contains a collection of all the fields on a given presentation space. Each element of the collection contains the elements shown in Collection Element Properties.

An autECLFieldList object provides a static snapshot of what the presentation space contained when the Refresh method was called.

Note:
You should call the Refresh method in the autECLFieldList object before accessing its elements to ensure that you have current field data. Once you have called Refresh, you may begin walking through the collection.

autECLPS Class

autECLPS performs operations on a presentation space. Its name in the registry is ZIEWin.autECLPS.

You must initially set the connection for the object you create. Use SetConnectionByName or SetConnectionByHandle to initialize your object. The connection may be set only once. After the connection is set, any further calls to the SetConnection methods cause an exception. If you do not set the connection and try to access a property or method, an exception is also raised.

Notes:
  1. In the presentation space, the first row coordinate is row 1 and the first column coordinate is column 1. Therefore, the top, left position has a coordinate of row 1, column 1.
  2. The autECLPS object in the autECLSession object is set by the autECLSession object.

The following is an example of how to create and set the autECLPS object in Visual Basic.

DIM  autECLPSObj as Object
DIM  NumRows as Long

autECLScreenDesc Class

autECLScreenDesc is the class that is used to describe a screen for HCL's Host Access Class Library Screen Recognition Technology. It uses all four major planes of the presentation space to describe it (text, field, extended field, and color planes), as well as the cursor position.

Using the methods provided on this object, the programmer can set up a detailed description of what a given screen looks like in a host side application. Once an autECLScreenDesc object is created and set, it may be passed to either the synchronous WaitFor... methods provided on autECLPS, or it may be passed to autECLScreenReco, which fires an asynchronous event if the screen matching the autECLScreenDesc object appears in the PS.

autECLScreenReco Class

The autECLScreenReco class is the engine for the Host Access Class Library screen recognition system. It contains the methods for adding and removing descriptions of screens. It also contains the logic for recognizing those screens and for asynchronously calling back to your event handler code for those screens.

Think of an object of the autECLScreenReco class as a unique recognition set. The object can have multiple autECLPS objects that it watches for screens, and multiple screens to look for, and when it sees a registered screen in any of the added autECLPS objects it will fire event handling code defined in your application.

All you need to do is set up your autECLScreenReco objects at the start of your application, and when any screen appears in any autECLPS that you want to monitor, your event code will get called by autECLScreenReco. You do absolutely no legwork in monitoring screens.

See Event Processing Example for an example.

autECLScreenReco Methods

The following section describes the methods that are valid for autECLScreenReco.

void AddPS(autECLPS ps)
Boolean IsMatch(autECLPS ps, AutECLScreenDesc sd)

autECLPS ps
PS object to monitor.

Return Value

None

Example

See Event Processing Example for an example.

IsMatch

Allows for passing an autECLPS object and an AutECLScreenDesc object and determining if the screen description matches the current state of the PS. The screen recognition engine uses this logic, but is provided so any routine can call it.

Prototype

Event Processing Example

The following is a short example of how to implement Screen Recognition Events:

Dim myPS as Object
Dim myScreenDesc as Object
Dim WithEvents reco as autECLScreenReco  'autECLScreenReco added as reference
 
Sub Main()
  ' Create the objects
  Set reco= new autECLScreenReco
  myScreenDesc = CreateObject("ZIEWin.autECLScreenDesc")
  Set myPS = CreateObject("ZIEWin.autECLPS")
  myPS.SetConnectionByName "A"
 
  ' Set up the screen description
  myScreenDesc.AddCursorPos 23, 1
  myScreenDesc.AddString "LOGON"
  myScreenDesc.AddNumFields 59
 
  ' Add the PS to the reco object (can add multiple PS's)
  reco.addPS myPS
 
  ' Register the screen (can add multiple screen descriptions)
  reco.RegisterScreen myScreenDesc
 
  ' Display your form or whatever here  (this should be a blocking call, otherwise sub just ends
  call DisplayGUI()
 
  ' Clean up
  reco.UnregisterScreen myScreenDesc
  reco.RemovePS myPS
  set myPS = Nothing
  set myScreenDesc = Nothing
  set reco = Nothing
End Sub
 
'This sub will get called when the screen Description registered above appears in
'Session A.  If multiple PS objects or screen descriptions were added,  you can
'determine which screen and which PS via the parameters.
 
Sub reco_NotifyRecoEvent(autECLScreenDesc SD, autECLPS PS)
  If (reco.IsMatch(PS,myScreenDesc)) Then
    ' do your processing for your screen here
  End If
End Sub
 
Sub reco_NotifyRecoError
   'do your error handling here
End sub 
 
Sub reco_NotifyRecoStop(Reason as Long)
    'Do any stop processing here
End sub

autECLSession Class

The autECLSession object provides general emulator related services and contains pointers to other key objects in the Host Access Class Library. Its name in the registry is ZIEWin.autECLSession.

Although the objects that autECLSession contains are capable of standing on their own, pointers to them exist in the autECLSession class. When an autECLSession object is created, autECLPS, autECLOIA, autECLXfer, autECLWindowMetrics, autECLPageSettings, and autECLPrinterSettings objects are also created. Refer to them as you would any other property.

Notes:
  1. The current version of this object is 1.2. There are two versions of this object; their ProgIDs in the registry are ZIEWin.autECLSession.1 and ZIEWin.autECLSession.2. The version-independent ProgID is ZIEWin.autECLSession. The ZIEWin.autECLSession.1 object does not support the properties autECLPageSettings and autECLPrinterSettings.
  2. You must initially set the connection for the object you create. Use SetConnectionByName or SetConnectionByHandle to initialize your object. The connection can be set only once. After the connection is set, any further calls to the SetConnection methods cause an exception. If you do not set the connection and try to access an autECLSession property or method, an exception is also raised.

The following example shows how to create and set the autECLSession object in Visual Basic.

DIM  SessObj as Object
Set SessObj = CreateObject("ZIEWin.autECLSession")
 
' Initialize the session
SessObj.SetConnectionByName("A")
' For example, set the host window to minimized
SessObj.autECLWinMetrics.Minimized = True

autECLWinMetrics Class

The autECLWinMetrics object performs operations on an emulator window. It allows you to perform window rectangle and position manipulation (for example, SetWindowRect, Ypos and Width), as well as window state manipulation (for example, Visible or Restored). Its name in the registry is ZIEWin.autECLWinMetrics.

You must initially set the connection for the object you create. Use SetConnectionByName or SetConnectionByHandle to initialize your object. The connection may be set only once. After the connection is set, any further calls to the set connection methods cause an exception. If you do not set the connection and try to access a property or method, an exception is also raised.

Note:
The autECLSession object in the autECL object is set by the autECL object.

The following example shows how to create and set the autECLWinMetrics object in Visual Basic.

autECLXfer Class

The autECLXfer object provides file transfer services. Its name in the registry is ZIEWin.autECLXfer.

You must initially set the connection for the object you create. Use SetConnectionByName or SetConnectionByHandle to initialize your object. The connection may be set only once. After the connection is set, any further calls to the SetConnection methods cause an exception. If you do not set the connection and try to access an autECLXfer property or method, an exception is also raised. The following shows how to create and set the autECLXfer object in Visual Basic.

autECLPageSettings Class

The autECLPageSettings object controls the page settings of a Z and I Emulator for Windows connection. Its name in the registry is ZIEWin.autECLPageSettings. This automation object can also be used in VB scripts.

The read-only property autECLPageSettings has been added to the autECLSession object. See autECLSession Class for information about how to use this property.

Note:
The autECLPageSettings object in the autECLSession object is set by the autECLSession object.

The following example shows how to create and set the autECLPageSettings object in Visual Basic.

DIM PgSet as Object
Set PgSet = CreateObject("ZIEWin.autECLPageSettings")
PgSet.SetConnectionByName("A")

Usage Notes

You must initially set the connection for the object you create. Use SetConnectionByName or SetConnectionByHandle to initialize your object. The connection can be set only once. After the connection is set, any further calls to the set connection methods cause an exception. If you do not set the connection and try to access a property or method, an exception is raised.

The properties CPI, LPI, and FontSize are dependent on the property FaceName. Therefore, if CPI, LPI, or FontSize are set before the FaceName is set, and if they are not valid for the new FaceName, different CPI, LPI, or FontSize values might be reconfigured in the connection. You should set the FaceName before setting the CPI, LPI, or FontSize. Otherwise, every time you set FaceName, query CPI, LPI, and FontSize and make sure that they have the desired values.

Restrictions

The connection associated with each method must be in a particular state for the method to succeed. If the restrictions are not met, an appropriate exception is raised.

The following restrictions must be satisfied while any property or method of the autECLPageSettings object is invoked.

Additional restrictions might apply for each specific property or method.

Connection types

The following connection types are valid for the methods in the autECLPageSettings class:

If a property or method is accessed or called on an unsupported connection, an exception is raised. Use the ConnType property to determine the connection type.

This property indicates the status of the connection to the host. The value is TRUE if the host is connected; otherwise, it is FALSE. CommStarted is a Boolean data type and is read-only.

Example
Dim PrSet as Object
Dim ConnList as Object

Set PrSet = CreateObject("ZIEWin.autECLPrinterSettings")
Set ConnList = CreateObject("ZIEWin.autECLConnList")
' Initialize the connection
ConnList.Refresh
PrSet.SetConnectionByHandle(ConnList(1).Handle)

' This code segment checks to see if communications are connected
' for A. The results are sent to a text box called
' CommConn.
If PrSet.CommStarted = False Then
 CommConn.Text = "No"
Else
 CommConn.Text = "Yes"
End If

APIEnabled

This property indicates whether the emulator is API-enabled. A connection is API-enabled or disabled depending on the state of its API settings (in a Z and I Emulator for Windows window, click Settings -> API).

The value is TRUE if the emulator is API-enabled; otherwise, it is FALSE. APIEnabled is a Boolean data type and is read-only.

Example
Dim PrSet as Object
Dim ConnList as Object

Set PrSet = CreateObject("ZIEWin.autECLPrinterSettings")
Set ConnList = CreateObject("ZIEWin.autECLConnList")
' Initialize the connection
ConnList.Refresh
PrSet.SetConnectionByHandle(ConnList(1).Handle)

' This code segment checks to see if A is API-enabled.
' The results are sent to a text box called Result.
If PrSet.APIEnabled = False Then
 Result.Text = "No"
Else
 Result.Text = "Yes"
End If

Ready

This property indicates whether the emulator window is started, API-enabled, and connected. This property checks for all three properties. The value is TRUE if the emulator is ready; otherwise, it is FALSE. Ready is a Boolean data type and is read-only.

Example
Dim PrSet as Object
Dim ConnList as Object

Set PrSet = CreateObject("ZIEWin.autECLPrinterSettings")
Set ConnList = CreateObject("ZIEWin.autECLConnList")
' Initialize the connection
ConnList.Refresh
PrSet.SetConnectionByHandle(ConnList(1).Handle)

' This code segment checks to see if A is ready.
' The results are sent to a text box called Result.
If PrSet.Ready = False Then
 Result.Text = "No"
Else
 Result.Text = "Yes"
End If

SetPDTMode

The SetPDTMode method sets the connection in PDT mode with the given PDT file or sets the connection in non-PDT mode (also called GDI mode).

Restriction

If this method is called with bPDTMode set to FALSE, PrintMode of the associated connection must already be set to SpecificPrinter or WinDefaultPrinter.

Prototype

void SetPDTMode(Boolean bPDTMode, [optional] String PDTFile)

Parameters

Boolean bPDTMode
Possible values are as follows:
String PDTFile
This optional parameter contains the PDT file name.

This parameter is used only if bPDTMode is TRUE. If this parameter is not specified and bPDTMode is set to TRUE, the PDT file configured in the connection is used. If there is no PDT file already configured in the connection, this method fails with an exception.

This parameter ignored if bPDTMode is FALSE.

Possible values are as follows:

Return Value

None

Example

Dim PrSet as Object
Dim ConnList as Object

  2. The associated connection must be in PDT mode.

Prototype

void SetPrtToDskAppend( [optional] String FileName)

Parameters

String FileName
This optional parameter contains the name of the Print to Disk-Append file.

If the file exists, it is used. Otherwise, it is created when printing is complete.

Possible values are as follows:

If this parameter is not specified, the file configured for this PrintMode in the connection is used. If there is no file already configured in the connection, this method fails with an exception.

Return Value

None

Example

Dim PrSet as Object
Dim ConnList as Object

Set PrSet = CreateObject("ZIEWin.autECLPrinterSettings")
Set ConnList = CreateObject("ZIEWin.autECLConnList")
' Initialize the connection
ConnList.Refresh
PrSet.SetConnectionByHandle(ConnList(1).Handle)

'If PDTMode, set PrintMode to pcPrtToDskAppend
If PrSet.PDTMode Then
 PrSet.SetPrtToDskAppend("dskapp.txt") 

SetPrtToDskSeparate

This method sets the PrintMode of the connection to Print to Disk-Separate mode. It also sets the appropriate file for this mode.

PrSet.SetConnectionByHandle(ConnList(1).Handle)

'Set PrintMode to pcWinDefaultPrinter
PrSet. SetWinDefaultPrinter

SetConnectionByName

The SetConnectionByName method uses the connection name to set the connection for a newly created autECLPrinterSettings object. In Z and I Emulator for Windows, this connection name is the short connection ID (a single alphabetical character from A to Z). There can be only one Z and I Emulator for Windows connection open with a given name. For example, there can be only one connection A open at a time.

Note:
Do not call this if you are using the autECLPrinterSettings object contained in the autECLSession object.

Prototype

void SetConnectionByName( String Name )

Parameters

String Name
One-character string short name of the connection. Valid values are A-Z.

Return Value

None

Example

The following example shows how to use the connection name to set the connection for a newly created autECLPrinterSettings object.

Dim PrSet as Object
Set PrSet = CreateObject("ZIEWin.autECLPrinterSettings")
' Initialize the connection
PrSet.SetConnectionByName("A")
' For example, see if PDTMode 
If PrSet.PDTMode Then
'your logic here...
End If

SetConnectionByHandle

The SetConnectionByHandle method uses the connection handle to set the connection for a newly created autECLPrinterSettings object. In Z and I Emulator for Windows, this connection handle is a Long integer.

There can be only one Z and I Emulator for Windows connection open with a given handle. For example, there can be only one connection A open at a time.

Note:
Do not call this method if you are using the autECLPrinterSettings object contained in the autECLSession object.

Prototype

void SetConnectionByHandle( Long Handle )

Parameters

Long Handle
The Long integer value of the connection to set for the object.

Return Value

None

Example

The following example shows how to use the connection handle to set the connection for a newly created autECLPrinterSettings object.

Dim PrSet as Object
Dim ConnList as Object

Set PrSet = CreateObject("ZIEWin.autECLPrinterSettings")
Set ConnList = CreateObject("ZIEWin.autECLConnList")
' Initialize the connection
ConnList.Refresh
PrSet.SetConnectionByHandle(ConnList(1).Handle)

' For example, see if PDTMode 
If PrSet.PDTMode Then
'your logic here...
End If

Support For Primary Interop Assemblies for Automation Objects

Automation objects exposed by HCL Z and I Emulator for Windows can be used by applications written in any language that targets the .NET framework. Managed .NET applications can program Z and I Emulator for Windows by using the Primary Interop Assemblies (PIA) that wrap the automation objects. Interop Assemblies are the mechanism with which managed (.NET) applications use COM-compliant objects. Interop Assemblies contain binding and metadata information, which enables the .NET framework (CLR) to load or marshall COM objects and wrap them for .NET applications. The PIA contains the official description of the COM types as defined by the publisher of those COM types. The PIA is always digitally signed by the publisher of the original COM type.

There are two ways a .NET application can reference an assembly.

The model for programming the types exposed by Interop Assemblies is very similar to COM. The methods, properties, and events exposed by the COM object can be accessed by any .NET language, using the syntax of the language. A sample application (ECLSamps.net) written in C# is provided in the \samples directory in the Z and I Emulator for Windows installation image. The sample demonstrates the simple usage of various Interop Assembly types.

For Visual Basic 6.0, projects that use Z and I Emulator for Windows automation objects and have been migrated to Visual Basic .NET using the conversion assistant wizard, you only need to replace the references that the conversion assistant wizard implicitly generates with the corresponding Z and I Emulator for Windows Interop references (from the \Interops directory) and recompile. The way to replace the references is to delete all the references generated by the conversion assistant and use Visual Studio .NET to add the .NET interop references. If you have registered the assemblies in the GAC and want to use them, add the references and set the Copy Local property for the Z and I Emulator for Windows Interop references to False.

The PIAs for the Z and I Emulator for Windows emulator automation objects are installed in the \Interops directory in the Z and I Emulator for Windows installation image. If the Z and I Emulator for Windows product installer detects that the .NET framework is present, it gives you the additional option to register the types in the GAC. While installing the assemblies in the GAC, the PIAs will also be placed in the registry, under the registry key of the corresponding type library.
