Hi all,

I am trying to create MFC Extension DLL using VS 2005.

1. First I have created a project of type MFC Extension DLL.
2. Then I added a dialog box with a text box, static text control and
buttons.
3. Then added a class for that dialog.
4. In dialog's header file I inserted AFX_EXT_CLASS, manually.
                    class AFX_EXT_CLASS CLogonParamDlg : public
CDialog
5. Then built and got .lib and .dll files.

1. In my client application, just commented ENUM line of dialog's
header file of MFC Extension DLL , as below. (In client its not
necessary and to avoid compiler errror due to
IDD_DLG_SET_LOGON_PARAM_DLG).
//enum { IDD = IDD_DLG_SET_LOGON_PARAM_DLG };

2. I have have added the above header file to project file. and added
header and lib file path.
3. Copied dll file to project's current working directory.
4. I have created object for the exported class implemented in
extension dll.
5. Then compiled client application without any warning and error. Then
executed.
6. But DoModal of extension dll's dialog class did not get executed.

I am trying this from last week. But didn't get success to create and
use mfc extension dll.
But don't know where I am doing wrong?

Can u please give me any tutorial link / explain steps to create and
use extension dll?
I would be happy if anyone send (purusothaman.a @ gmail.com) me sample
extension dll creation project and also a client application which uses
created extension dll.

Here I think source code may help u to identify the problem.
