ActiveQt self registration fails
Message 1 in thread
I created a simple activeX using the ActiveQT framework, I was able to test
the active using ActiveX Control test container, but when I tried to load
the activeX from another application (SolidWorks) in my case the application
hangs.
I tried to investigate the activeX using OleView.Exe and OleView also hangs,
I tried to debug this and it seems that IViewers.dll is loaded many times.
I also tried to add the activeX to vs2005 and I received the message
self-registration failed, I found an old post saying the problem should have
been fixed in QT4.2.
I am using QT4.3.3 and it still does not work for me.
I will appreciate the help of a QT ActiveX champion.
Thanks,
Ashraf

Is this an executable server, or a DLL server? Does the self-registration
problem exist with the examples that come with Qt? What is IViewers.dll in
this context? Is this your server DLL, or a DLL your server depends on?

Hello Volker,
This is a Dll server, and the same problem happens even with the QT
examples.
What I was doing is simply using the ActiveQt wizard from inside vs2005 SP1.
And using the default to generate a Dll server.
Using the created activeX with ActiveX Control test container or with the qt
test application works fine.
IViewer.dll is a Dll that OLE/COM view loads, I used devenv and tracked
loading the dlls, as soon as it reached IViewer when I tried to load the QT
based activeX is was trying to load it multiple times, and the operation
never finished, this was part of the investigation.
The problem for me is not being able to add the QT based ActiveX to the
controls in visual studio.
Thanks,
Ashraf
