What to do if clawPDFObj.IsInstanceRunning is True

[vasvovec]

Hello.

I want to use clawPDF via COM то print some reports to PDF. When my code execution stopped with an error I try to fix and restart it. But now it stopped with error on call:
clawPDFQueue.Initialize
ОК. I found this advice by searching. Then I added a check by using :

IF clawPDFObj.IsInstanceRunning = True THEN
  clawPDFQueue.ReleaseCom

And in the process of execution I see that clawPDFObj.IsInstanceRunning = True , but I don't see clawPDF in the task manager. And I get an error:

(clawPDF.ComImplementation): No COM Instance was found.

And if I execute code like this:

IF clawPDFObj.IsInstanceRunning = True THEN
  IF clawPDFQueue.Count > 0 THEN ...

I get an error:

The call to member Count failed. clawPDF returned the following message:
Object reference not set to an instance of an object.

How to find and kill existing clawPDF process? Or how to get the reference to an instance of clawPDFQueue?

I found a solution. I add 3 lines of code to the method ReleaseCom() in .\src\clawPDF\COM\Queue.cs
Was:

public void ReleaseCom()
{
    if (_isComActive)
    ...
    else
    {
        throw new COMException("No COM Instance was found.");
    ...

With my changes:

public void ReleaseCom()
{
    if (_isComActive)
    ...
    else
    {
        if (IsServerInstanceRunning)
            ThreadManager.Instance.PipeServer.Stop();
        else
            throw new COMException("No COM Instance was found.");
     ...
