screenshot

问题 I want to take a screenshot of some specific window (e.g calculator). Here is the code I have written according to this discussion: // Get the window handle of calculator application. HWND hWnd = ::FindWindow(0, _T("Calculator")); RECT r; GetWindowRect(hWnd, &r); int x[2]; int y[2]; x[0] = r.top; x[1] = r.bottom; y[0] = r.left; y[1] = r.right; HDC hScreen = GetWindowDC(hWnd); HDC hDC = CreateCompatibleDC(hScreen); HBITMAP hBitmap = CreateCompatibleBitmap(hScreen, y[1] - y[0], x[1] - x[0]);

问题 I am working on a solution capturing screen-shots of websites. I am using the default example mentioned at slimerjs.org to get the job done.

But when I try this url: http://votingbecause.usatoday.com/ I only get screenshot of the set resolution (default:

问题 I have created a minimal example with pyqt designer, that changes the text of a label when a button is pressed and is supposed to present a screenshot in the window, via the label.

问题 After doing a lot of research on this topic, though I found a few answers, I could not understand how the MediaProjection API works.

Please help me 回答1: This is tricky way to achieve this. First of all you need to create
