Running Mach3 via VB.NET
« on: October 20, 2009, 07:23:44 AM »
Good morning :-)

After a long run of extensive searching and finding great help through the forums, I've hit a roadblock.

I'm trying to control Mach3 through VB.net and have the basic foundation.  I'm able to do basically everything I want with the Mach4 COM API, but my problem is that every time I restart my vb.net program, I get an error that says "Cannot create ActiveX control" on the line that reads: mach = GetObject(, "Mach4.Document")

Here is some simple code:

Code: [Select]
Dim mach As Mach4.IMach4
Dim scriptObject As Mach4.IMyScriptObject

mach = GetObject(, "Mach4.Document")
scriptObject = mach.GetScriptDispatch()

scriptObject.LoadFile("11 CUX56.TXT")

scriptObject.RunFile()

While (scriptObject.IsMoving() <> 0)
    System.Threading.Thread.Sleep(1)
End While


If I close Mach3 and restart it after the error, the program runs fine.  The problem occurs when I close my vb.net program and reopen it (rebuild it, to be exact) without closing Mach3.

Am I not creating my object properly?  Is there a code to reset the control or to close the link to reopen it?  If I run the code with Mach3 closed, I get the same error.

I'm guessing it's related, but when I close Mach3 after getting the error, I get a popup box that says "Error Found  ,Art Code: 9991, Attempt Recovery?".

Any ideas?  Thank you very much in advance!

Unless there is more detail with the create ActiveX control, I'd focus my attention on the 9991 error.  I just did a quick search, and there are a number of threads about it.

Thanks.  It seems like no one knows the answer.  Yea, I'll check out the threads on the other error and maybe that will kill two birds with one stone.
