I am beginner with COM. Currently I am trying to write a COM server(*.EXE) to receive messages from other process. So, I plan to create a hidden dialog for my COM server.

I just created a ATL Dialog class using VS2010 and the "Add class wizzard".

class CMyDlg: 
	public CAxDialogImpl<CTestDialog>

After initialized

CMyDlg dlg;

It just hang on every thing.

Then I changed another method

CMyDlg dlg;

Nothing happened! Just an error code: 1813. That means The specified resource type cannot be found in the image file.

I can't understand why this happen?
The Dialog resource was created by the wizzard.

I searched from google and some forum for the whole 2 day, nothing was found.

Could you please give me some idea?

how can you call doModal on a hidden box?

It might be a problem in Create method: you should use a template name, not a NULL statement. If you did not derived 'Create' virtual method, I suppose, the compiller will use standard CDialog template, not the inherited one.

THe create function parameter was hWnd. Because my application was a ALT service, no window existed.

Have you tried to create standard CDialog window?
Although it might be a problem. If there is no any window, you can try to attach your dialog to desktop:
CWnd wnd;
wnd.Attach( GetDesktopWindow() );
CDialog dlg;

I ignored that my OS was Windows7. The services dialog, if successfully created, would work at Session 0. In this Session, no message can arrive from other session.
