Have you created the dialog and its class, I assume you did.

in your SDIview or Mainframe class, declare a new class of your dialog class.

CPP / C++ / C Code:

CMyDialog MyDialog;

and in the implementation, just call domodal to pop a modal dialog;

CPP / C++ / C Code:

MyDialog.DoModal();

for a modaless dialog,use this code:

CPP / C++ / C Code:

MyDialog.ShowWindow(SW_SHOW);

Thanks i have created my dialog, created a class named it MyDialog but when u say in the implementation where exactly do i add the

CPP / C++ / C Code:

MyDialog.DoModal();

i have included the header i the main frame but which function do i include this call

It depends on when you want to pop the dialog. Lets say that the dialog should pop when user clicks on a button in the toolbar, the ID of the button is ID_POPDIALOG.

CPP / C++ / C Code:

// add this in the mainframe.h

//{{AFX_MSG(CMainFrame)
	afx_msg void OnPopDialog();
//AFX_MSG

// In the mainframe.cpp
BEGIN_MESSAGE_MAP(CMainFrame, CFrameWnd)
	//{{AFX_MSG_MAP(CMainFrame)
             // Add this here, it will handle the command message of the button
             // and call OnPopDialog()
	ON_COMMAND(ID_POPDIALOG, OnPopDialog)
	//}}AFX_MSG_MAP
END_MESSAGE_MAP()

//this is still in the mainframe.cpp 
void CMainFrame::OnFormatFont() 
{
     //show the dialog
     MyDialog.DoModal();
}

void CMainFrame::OnFormatFont() 
{
     //show the dialog
     MyDialog.DoModal();
}

what i want is that when i run the program the dialog will be already there. when the menu is displayed the dialog should also be there (attaching the dialog to the menu)
thanx

Thats Kind of hard to do.. Just follow the instructions below:

CPP / C++ / C Code:

in the mainframe.h file
#define WM_STARTUP (WM_APP +1)

	//{{AFX_MSG(CMainFrame)
             //Add this here
	afx_msg void OnStartUp(WPARAM wParam, LPARAM lParam);
	//}}AFX_MSG

then in the mainframe.cpp file
BEGIN_MESSAGE_MAP(CMainFrame, CFrameWnd)
	//{{AFX_MSG_MAP(CMainFrame)
	// add this here
             ON_MESSAGE(WM_STARTUP, OnStartUp)
	//}}AFX_MSG_MAP
END_MESSAGE_MAP()

and add the handler

void   CMainFrame::OnStartUp(WPARAM wParam, LPARAM lParam)
{

    MyDialog.DoModal();
}

Then at the end of OnCreate()  add
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
...
...
...
PostMessage(WM_STARTUP, 0,0);
return 0;
}

That should do it...

void   CMainFrame::OnStartUp(WPARAM wParam, LPARAM lParam)
{

    MyDialog.DoModal();
}

Then at the end of OnCreate()  add
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
...
...
...
PostMessage(WM_STARTUP, 0,0);
return 0;
}

That should do it...

thanx for the help also adapted ur first idea and it worked

will try this one thanx
