How to create a screenshot of the program window using WinAPI & amp; C #?
I am sending the message to the window WM_PAINT (0x000F) , which I want to screenshot, handle wParam = HDC , but no one in my picturebox There is no screenshot. If I send a WM_CLOSE message, then all the voting (close the target window). What do I do with WM_PAINT ? Maybe HDC is not a WinForms component? The public static extern Int64 SendMessage (IntPtr hWnd, uint message, IntPtr wParam, etc.); IntPtr lParam); ..... Send Message (TargetWindHandal, 0x000F, PictureboxHandle, Intupet.Zero);
pictureBox.Handle handle a window, no DC handle There are several guides online for screenshots. See also in reply to Silicon
