Yes. Now I am checking the analyze() function. If you have any clue please advice me. Thank you very much for your help.

Many thanks.

I suspect it's the while() loop condition. It appears you are reading the file until EOF is encountered or some event is signaled. Is that correct?

Live Messenger style window, having problems with border update and child controls flickering

Nathan Going25-Aug-08 2:36

I've modified CDialog to draw a window in a Windows Live Messenger style, using SerWindowRgn and with a custom drawn client area. One of the problems I’m having is when you size the window smaller, you see a gray border which shouldn’t be there. Please see My Code[^]. Am I handling the custom drawing correctly? Another problem is with controls flickering when I resize. I understand that this is caused by invalidating the entire window, but that's the only way I can cause the whole background to update. I will be adding in dynamic positioning and ownerdrawn controls.

Any help would be greatly appreciated,

Thank you.

Are you sure OnClose is not called? Are you not using OnCancel to close the dialog?

Somethings seem HARD to do, until we know how to do them.

How do you 'close' the window?

I find the answer by trial and error

PostNcDestroy is called when a non modal page is closed.

Thank you for your help.

The CWnd::OnDestroy() should be called as per documentation.

Extract from MSDN : "This method is called by the framework to inform the CWnd object that it is being destroyed. OnDestroy is called after the CWnd object is removed from the screen."

I guess, something went wrong when you add your message handler for WM_DESTROY. Try once again by adding WM_DESTROY message handler by using class wizard.

Jijo.

gr8, and mfc is just a wrapper over win32.
In OnCtlColor of your class do this

if(pWnd->GetDlgCtrlID ()==IDC_STATIC1) //id of static control
{
pDC->SetTextColor(RGB(255,0,0));

}

Somethings seem HARD to do, until we know how to do them.

MFC is a wrapper framework over win32 api to make our life easier. Well, you could add ON_WM_CTLCOLOR() in you message map and implement afx_msg HBRUSH OnCtlColor( CDC*, CWnd*, UINT );

Hi,

Try like this...

HBRUSH CDialog::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
	HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

    if( pWnd->GetDlgCtrlID() == IDC_STATIC1)
    {
        hbr = CreateSolidBrush(RGB(240, 240, 240));
        return hbr;
    }
	return hbr;
}

What to do.

See the Extras section of this article. It changes the text to bold, but using color instead is a trivial matter.

Best way to create a dialog-based app displaying several dialog pages, similar to Microsoft Installer Engine

Erik25-Aug-08 1:46

Erik

25-Aug-08 1:46

Hello,

I am planning to write a dialog-based application that behaves similar to the microsoft installer, i.e. I will have to display several pages of information where the user can read text, and make some desicions using several controls. Each time the user presses the "Next" button in my app, he will be presented a new dialog-page with new information and new controls. Optionally, the user can press the "Previous" button to step back one page.

My question now is very simple: what is - technically - the best way to create this kind of application using MFC. I have already thought about having various dialog windows, which are controlled from within my "App" class. Another possibility would be to have all controls of all available pages in only one dialog resource, and make only the ones visible that are required in a certain step, and hide all the other ones.

I don't like either way, since there are disadvantages, so I am asking for your oppinion: how would you create this app?

Thanks alot.
