Hi, I have an OCX control that runs OK on a dialog box when it is used in MFC dialog based application. However, when I try to drop this control in a dialogbox and use CExtResizableDialog as a base calss, I cannot display the dialogbox using DoModal(). However, when I remove the control from the dialog box, I could display it using the same function i.e. DoModal(). Any idea what is going on ? Thanks, Saroj

Dear Saroj,
There are two types of MFC DLL extension libraries: EXE extensions and regular DLL extensions (RDE). Prof-UIS 2.25 supports RDE configurations (see build configurations of the profuisdll project).
You need to define the __PROF_UIS_FOR_REGULAR_DLL symbol in the preprocessor settings of your project. This make your project use the RDE version of Prof-UIS automatically. Besides, initialize the RDE library manually. Place the following code at the beginning of the InitInstance virtual method of your CWinApp -derived class: BOOL CApp::InitInstance()
{
if( ! ::AfxOleInit() )
{
ASSERT( FALSE );
return FALSE;
} // if( ! ::AfxOleInit() )
CExt_ProfUIS_ModuleState::InitExtension(
AfxGetStaticModuleState()
);

Hi Tech Support,
I tried what you suggested and got errore during runtime. Unfortunately, the error is in message pump loop and I cannot even launch my application. To be more precise, error is from the line # 6121 of file ExtPopupMenuWnd.cpp.
The error message is as below: Unhandled exception at 0x00744f55 (ProfUIS225ud-RDE.dll) in Optiview-nd.exe: 0xC0000005: Access violation reading location 0x00000000. I don’t know what the cause of this problem is. Your help is highly appreciated. If I cannot resolve this problem, I am kinda stuck with my project because I cannot use the OCX that I MUST use. Regards, Saroj
