In the property sheet, override the OnCommand() method. Then add the following code:

if (BN_CLICKED == HIWORD(wParam) && IDHELP == LOWORD(wParam))
{
    // help stuff here, like calling WinHelp()
    return TRUE;
}
 
return CPropertySheet::OnCommand(wParam, lParam);

"In the MFC application the dialog is initialised or called using Create function like this

dlg->Create(IDD_DIALOG, this);

This will call the OnInitDialog() function automatically, when the application is configured in Debug mode, but it is not called when it is in Release mode. Can anybody tell me what could be the reason?"

thanks

How are you verifying that the OnInitDialog() method is not being called?

In debug mode i can confirm this using break point but in release mode i put one messagebox inside the oninitdialog fucntion which didnt not called in release mode.....and in that function only i am showing the controls in dialog like this....
e.g m_Combo.ShowWindow(SW_SHOW);

since oninitdialog is not called my controls in the dialog are displayed.

By chance are there any ActiveX controls on the dialog? What happens if you use a modal, instead of a modeless, dialog?

Yes ....there is an Active-X control in that dialog...
here i am explaining in detail.....
This dialog is added as a property page into the propertysheet. This dialog contains 2 static texts, 2 combo boxes and one MSChart Active-X control.
and in release mode all are not displayed where they are shown in
OnInitDialog() function which has been not called.

Thanks

Just for grins, remove the ActiveX control from the dialog template and see if that makes a difference. If it does, it sounds like the ActiveX control is not properly registered, or a call to AfxEnableControlContainer() has not been made (correctly).

I have deleted the mschart active x control and tested still the other controls like combo boxes are not displayed. The active x control has been registered in windows registry using the following command

regsvr32 C:\winnt\system32\mschrt20.ocx

and the function AfxEnableControlContainer() is also called in InitInstance() function and the required header file #include <afxdisp.h> is also included in the stdafx.h file.

Still the problem exists. Please help me to solve this problem as soon as possible. we have a release by this week end.

thanks

Does that mean you are using a CPropertyPage (instead of a CDialog) object? If so, have you looked at the OnSetActive() method?

sorry to tell you that we are using CDialog only....not property page....

the problem is CResults is a class devired from CPropertyPage, and to this property page.....at the down i am adding 4 more pages (CChart, CSummary...etc) which are derived from CDialog.
Dialogs are not displayed in CChart, which dont have OnSetActive() function as it is a CDialog and here i am using Active-X control.

Don't these two statements contradict each other?

I'm not sure what this means.

It sounds to me like you have a CPropertySheet-based application, with four CPropertyPage objects on the sheet. Is that correct?

You may e-mail me the project if you wish where I'll be more apt to tell what is wrong. Send a PM for my address.
