    Maximize hides task bar

    Visual Studio 2008 pro

    MFC Dialog app.

    In OnInitDialog() I include the following lines:

    ShowWindow(SW_SHOWDEFAULT);
    ShowWindow(SW_MAXIMIZE);

    This maximizes the window but it overwrites the task bar. How do I maximize the window of the app and still have the task bar visible ??

    Thanks

    Not always. It depends on the properties of the task bar.

    If you are referring to the property "Keep the taskbar on top of other windows" that is selected and my app still "overwrites" it.

    Re: Maximize hides task bar

    Ok I figured out what the deal was with this and I will put this up in case someone else runs into the same problem.

    It seems that if you remove the maximize box and you use ShowWindow(SW_MAXIMIZE) your app will fill the screen, even overpainting the task bar, if you leave the maximize box in the project and use the same command, the taskbar will remain visible.

    My issue was that I only wanted the app to run maximized AND still have the task bar visible without allowing the user access to a restore button.

    You can accomplish this if you override the OnSysCommand. The app I was writing already included an OnSysCommand function to handle the About Box so I modified it like this and got the results I wanted.
    Code:
    void CMyApp::OnSysCommand(UINT nID, LPARAM lParam)
    {
    	
    	if ((nID & 0xFFF0) == IDM_ABOUTBOX)
    	{
    		CAboutDlg dlgAbout;
    		dlgAbout.DoModal();
    	}
    	else
    	{
    		if(nID == SC_RESTORE){
    			if(IsIconic())
    				ShowWindow(SW_MAXIMIZE);
    		}else{
    			CDialog::OnSysCommand(nID, lParam);
    		}
    	}
    }
