HACL终端仿真器自动化：ECLPS对象和线程 [英] HACL terminal emulator automation: ECLPS objects and threading

问题描述

我正在使用IBM HACL进行终端仿真器自动化。在执行线程中，我可以访问HACL编程对象及其属性/方法。我的意图不是阻止主线程，而是通过后台工作人员完成工作。在这里我所有的尝试都失败了。



我尝试过：



这有效：

I'm working on terminal emulator automation using IBM HACL. In the execution thread I can access the HACL programming objects and their properties/methods. My intention is not to block the main thread, but have the job done via background worker. Here all my attempts failed.

What I have tried:

This works:

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles Me.Load
    Dim pConnList As AutConnListTypeLibrary.AutConnList
    pConnList = New AutConnListTypeLibrary.AutConnList
    pConnList.Refresh()
    Debug.Print("Number of sessions: " & pConnList.Count)
'Result:
'Number of sessions: 2
End Sub

但后台工作人员无法做到这一点。在创建对象实例时会抛出异常：

But the same is not possible from the background worker. When creating the instance of the object the exception is thrown:

Private Sub bw_DoWork(sender As Object, e As DoWorkEventArgs) Handles bw.DoWork
    Dim pConnList As AutConnListTypeLibrary.AutConnList
    Try
        pConnList = New AutConnListTypeLibrary.AutConnList
        pConnList.Refresh()
        Debug.Print("Number of sessions: " & pConnList.Count)
    Catch ex As Exception
        Debug.Print(ex.Message.ToString)
'Result:
'Exception thrown: 'System.InvalidCastException' in Pcomm test.exe
'Unable to cast COM object of type 'System.__ComObject' to interface type 'AutConnListTypeLibrary.AutConnList'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{3CB39CC1-6F18-11D0-910D-0004AC3617E1}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).
    End Try
End Sub

推荐答案

使用后期绑定

pConnList = CreateObject（PCOMM.AutConnList）

应该有帮助



如果您想使用intelisense您可以尝试使用
