Hello, everyone.
I have some trouble while registering my ActiveX control.
When I build it in VS2008, it stop at "Registering output..." and will never be back until I press "Cancel" .Then I try to register the file by regsvr32.exe. The command return directly with no error or any other information, but I can find the process "regsvr32.exe" in Windows Task Manager, and I have to kill it by myself.
I have no idea what happened,is there anyone can give me help? :((

Solution 1

Try to empty the function DllRegisterServer(..)
and then add line to line (slowly) to find the "catch".

You could also use the ::MessageBox(..) function after each line there
to "control" the execution :)

Thank you for your answer.I empty DllRegisterServer() ,but the problem still exist. Is it possible that the error happened before DllRegisterServer() ?How can I locate it?

The function DllRegisterServer() is below,it is generated by VS2008, I didn't change it.
STDAPI DllRegisterServer(void)
{
AFX_MANAGE_STATE(_afxModuleAddrThis);

if (!AfxOleRegisterTypeLib(AfxGetInstanceHandle(), _tlid))
return ResultFromScode(SELFREG_E_TYPELIB);

if (!COleObjectFactoryEx::UpdateRegistryAll(TRUE))
return ResultFromScode(SELFREG_E_CLASS);

return NOERROR;
}

OK... :) Have you any global/static class/structure instances with provided constructors in your code ?(1) Have you changed the DllMain code ?(2)

I didn't change the DLLMain code,but there are several global structure instances in the program.Do you mean these instances initialize in the regester process, and some of them conflict with regsvr32.exe?

Any constructors (for example with endless loops) of the global things will be processed at the loading of their DLL (earlier as its registration could be called)... :)

Thank you, I try to find the source of evil~~`(*n_n*)'

Try also to attach the VS Debugger (menu item "Debug") to the hanging process of regsvr32.exe and press "Break" then. You will see the call stack. One of your functions may lie at its top... :)

Thank you so so so much,I fixed my problem~~~There is a global timer queue in my program,It course the problem.
