Need a help on Multiple Dialog Application...

ANJANEYA_PRASAD · #1 28-Aug-2008, 07:32

Hi All

,

This is Anjaneya Prasad. I am very new to Visual C++ 6.0.

I am trying to develop an application which may have two Modal dialogs.
One DoModalling the other.

I tried to overwrite the virtual function OnOK and OnCancel in the second Dialog.

Unfortunately the second Dialog is not yet all closing, and no event is occuring in the second dialog(Even the mouse event events also)

.

Do i need to do more than i did?

If i wish to DoModal the Third Dialog from the Second Dialog, how can i do that?

Can any one help me in this regard?

Here i am attaching my code.

Thanks and Regards,

You are close, but the concept is a little off...

Within the SputnikInterface01Dlg.cpp file is this event handler when the configure button is clicked:

CPP / C++ / C Code:

void CSputnikInterface01Dlg::OnConfigure() 
{
	// TODO: Add your control notification handler code here
      CDialog configDlg(IDD_DIALOG4);

	INT_PTR nRet = -1;
	nRet = configDlg.DoModal();
}

The problem is that a (thought to be) 'configure' dialog is being created from a resource (the IDD_DIALOG4) using the CDialog class. Which is all well and good for having a basic object of CDialog, BUT this is NOT creating an instance of the configureDlg class, which means that none of the 'configure' functions are being called, and so, nothing happens with the button clicks.

Your custom configure class already inherits from CDialog, as shown by the class declaration: [in configureDlg.h]

CPP / C++ / C Code:

class CconfigureDlg : public CDialog  // <-- note the CDialog

So that function above merely needs modifying to use your configureDlg class as so:

CPP / C++ / C Code:

void CSputnikInterface01Dlg::OnConfigure() 
{
	// TODO: Add your control notification handler code here
       CconfigureDlg configDlg;  // use the CconfigureDlg class

	INT_PTR nRet = -1;
	nRet = configDlg.DoModal();
}

Also, note that:
1. The header file for the CconfigureDlg class needs to be added to the SputnikInterface01Dlg.cpp file.
2. In file configureDlg.cpp, keep the CDialog::OnOK() and CDialog::OnCancel() functions enabled, as these are needed for the inherited CDialog class.
3. If the OnClickedCancel(), and OnClickedOk() are extra's (assuming these were created trying to debug the problem) they can probably be eliminated.
