How to get the window state?

[Sheela Krishnan]

Hi, I am trying to get the windowstate of a window based on its process id. Below is what I tried... But the GetWindowPlacement method returns false most of the times inspite of the length of the windowplacvement object being initialized. Even if the method returns true, its showCmd is always NORMAL. While testing my window was always MAXIMIZED! Can anyone point what I am missing...? Can anyone explain how the window state is maintained. ...... Thanks! FormWindowState GetWindowState(int processID) { FormWindowState formWindowState = FormWindowState.Normal; WINDOWPLACEMENT windowPlacement = new WINDOWPLACEMENT(); //If there is not proces by this ID, then return Minimized. uint processHandle = (uint)Process.GetProcessById(processID).Handle; if ( processHandle.Equals(0) ) { return FormWindowState.Minimized; } windowPlacement.length = Marshal.SizeOf(windowPlacement); bool test = Win32Wrapper.GetWindowPlacement(processHandle,ref windowPlacement); if ( windowPlacement.showCmd == SHOW_STATE.SW_SHOWMINIMIZED ) { formWindowState = FormWindowState.Minimized; } else if ( windowPlacement.showCmd == SHOW_STATE.SW_SHOWMAXIMIZED ) { formWindowState = FormWindowState.Maximized; } }

Assuming that Win32Wrapper.GetWindowPlacement() indeed does only encapsulate the native Win32 call, you're simply passing the wrong value. GetWindowPlacement()[^] expects a handle to a window, not to a process. If you're interested in the state of the main window of a process you can use the Process.MainWindowHandle Property[^] to obtain the correct handle. Best regards Dennis
