DLLs & Dialogs

[Guest_imported]

I’m trying to learn more about creating & using DLLs. I’ve been doing okay but have now hit a problem;
I’ve inserted a dialog into my DLL project and created a class to handle it via Class Wiz in the same way that I’ve done successfully a number of times when creating a simple .exe. The class itself is created without a problem and I’m able to access it from my app. however, when I execute DoModal nothing happens. I would expect the dialog to appear, but it doesn’t. I’ve spent a while now trying to guess what step I’m missing out but have gotten nowhere.
I’d be very grateful for any ideas anyone might have.
Cheers.

If it's the problem i thought, it is quite trichy.
Just test that:
In the function of your DLL where you want to display the dialog:

//Get DLL Handle
HMODULE hDLL = GetModuleHandle("MyDLL.dll"

// Get handle of the caller
HINSTANCE hEXE = AfxGetResourceHandle();

// Set that we use the dll resource for the rest of this code
AfxSetResourceHandle((HINSTANCE) hDLL);

CMyDlg dlg;
if( dlg.DoModal() != IDOK)
{
return;
}
// Set back resources on the caller
AfxSetResourceHandle(hEXE);

The problem as you see is that the dll use by default the exe resource and we have to tell that the resources to use is the dll ones.
