DDE problem: Windows cannot find path....

Question

Hi, I have problem with handling DDE if I want to show CDialog before creating CFrameWnd. I do it in two ways:

1) create MyApp (CWinApp) which has overriden OnDDECommand. Inside MyApp::InitInstance() I create MainFrame (CFrameWnd). DDE works well, OnDDECommand handles DDE calls.

2) before MainFrame I want to show MyDialog (CDialog), but in such situation I don't get OnDDECommand. I tried to handle WM_DDE_EXECUTE (and other WM_DDE_ messages) inside MyDialog, but such messages don't come.

Regards, Bogdan

1. Keep your CFrameWnd hidden at startup.
2. Let the CFrameWnd process the DDE message.
3. During processing open the dialog.
