Runtime binding to an ActiveX Object

[erikg]

I have an a LabVIEW application that I would like to build into a dll. The

problem comes in with the binding to an ActiveX object - MultiSim. I am

calling MultSim as an ActiveX object in the code, which works fine in the

developemnt system. When I build a dll and run it, it crashes on the

automation open.

To connect to MultiSIM as an ActiveX object, I needed to browse to the

multisim.tlb file.

Perhaps I need to register the object?

Thanks!

Possibly, try the following:

To register DLLs or OCXs:

1. On the Taskbar, select Start > Run
   
2. In the Open field, type regsvr32 "<path>\NameOfFile.extension", where <path> is the directory where the file is located on your computer and NameOfFile.extension is the name of the file. For example:
   regsvr32 "C:\Windows\System32\Mydll.dll"
   
3. Press Enter.
   
4. If the file registers successfully, you'll see a message telling you it succceeded:
   

To register an executable, or .exe, file:

1. On the Taskbar, select Start > Run
   
2. In the Open field, type "<path>\NameOfFile.exe" /REGSERVER, where <path> is the directory where the file is located on your computer and NameOfFile.exe is the name of the file. For example:
   "C:\Program Files\MyAppLocation\MyApp.exe" /REGSERVER
   
3. Press Enter.
   

Most executables do not display any message boxes when registered. It depends on how the application is created. Some applications when registered may open on your computer.

Hope this helps.

Type Libraries

Type libraries are binary files that contain all type information needed to utilize procedures and classes in a DLL. To register a type library, you can use regtlib.exe as follows:

1. Select Start
