You can create a hook for the message box and then display the image as a background on it...

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

By using:
SetWindowsHookEx , CallNextNextHookEx and UnInstallHook

Did you check that whether there is a thread that lock's itself or some infinite while loop that you are using in your code. If you can post some code relevant to your application and this query you are more likely to get to the solution.

Code is very lengthy.
I can write more specific.
I had create 2 dialog boxes.
First I had create one more dialog box with splitters, then i showed these first two dialogs in splitters. I accessed the controls on dialogs from the third dialog box.
Now I used Tab Control instead of splitter plane.
Then start problem.
I am able to see the two dialogs in diferent tabs but not able to access them. When I tried to access them then application get hangs.

What do you mean by not able to access them.
How are you creating the third dialog. Modal or modeless?

You would be better searching for a Glg toolkit forum, where the members may be better able to help you. In normal code we would simply call SetTextColor(), but your Glg would have it's own methods of doing this.

Override WM_CTLCOLOR.

HBRUSH COnlyForYou::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
 HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
 HBRUSH BkgBrush = ::CreateSolidBrush(RGB(0,0,255));		
    if(GetSafeHwnd()==pWnd->GetSafeHwnd())
        {
			pDC->SetBkColor(RGB(0,0,255));
			hbr = BkgBrush;
        }

    return hbr;
}

You dont need to call this event you need to insert this event to your class

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
