Hi All,

I am developing a windows application(Sample). I am trying to pull up the application (bring to front) from another application. I used the following codes,

getProcess = Process.GetProcessesByName("Sample");

if (getProcess.Length > 0)
{
    WINDOWPLACEMENT wp = new WINDOWPLACEMENT();
    app_hwnd = getProcess[0].MainWindowHandle;
    GetWindowPlacement(app_hwnd, ref wp);
    wp.showCmd = 1;
    ShowWindow(app_hwnd, 9);
    SetForegroundWindow(app_hwnd);
}

It's working on fine. I called this function, whenever an input device button is clicked. I repeat the same each and every time fast then my
"Sample" application shows a blank white screen. How can I solve this solution? I don't want to display a white screen.

Thanks in advance.

Solution 1

It doesn't seem to know that it's getting the focus. To see if this is the case, add an event handler for the main form's Focus event, and have it display a dialog, or make a system log entry.

Hi,
Thanks for your quick response. I am sure this is not any focus error. I tried that one but I didn't get any errors.I am sure this is happened while the application repaint or rendering controls each and every time while the application is coming to front. I did the same with some other application but I am not getting this issue. In my application there are many controls and background images are applied. So I am getting this issue with my application only.
