schnitzel,

I downloaded and installed VB express. Tried it on the DYMO .NET VB example included in the SDK. After it converted the project it compiled it and ran just fine. I was able to open the label, fill in the data fields and it printed my labels including the barcode. So I guess the COM objects are registered and working OK.

I still can't think of a good reason I have to take the COM object instantiation out of the constructor. This project has a Main Form where I call each job from the menu by creating another form where I do the work and print my labels. Something in Qt must need to be done in the constructor before I can create these two COM objects.

I hate it when I don't know what is going on...

high_flyer,

I may be wrong, but I thought COM objects were reference counted and didn't need to be manually deleted. At least that is the way they always worked in Delphi and C#. When the last variable went out of scope that referenced the COM object the object was automatically deleted.

Is that not true for Qt?
