Capturing Screen

Capturing Screen

• AmarAtAIR

  You could use a 3rd party product that contains a simple COM component called Print Screen Deluxe from American Systems.  Go to www.americansys.com.

  Your code could look like this:

  void Foo()
  {
      CInterface psd;

      psd.CreateDispatch("PrintScreenDeluxe.Interface");
      psd.CaptureFullScreen();
      psd.SaveFile("c:\\tmp\\FullScreen.BMP");
      psd.ReleaseDispatch();

  }

  I hope this helps.

  On your keyboard towards the right side there is a button called insert, straight above that is a small button called prt scr/sysrq, push that button to take a picture of the current screen, it saves the image to the clipboard meaning that if you open an advanced word application such as WordPad or Microsoft Office Word then when you paste it pastes the image onto the Word Application. There you go!

  Send a VK_SNAPSHOT, then copy it from the clipboard (OpenClipboard, GetClipboardData etc)

  // Simulate a key press
  keybd_event( VK_SNAPSHOT, 0x41,KEYEVENTF_EXTENDEDKEY | 0,  0 );

  // Simulate a key release
  keybd_event( VK_SNAPSHOT,0x41,KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP,0);

  You could use another 3rd party product, he generates screenshots in a bmp files and avi files, search about Camtasia in Google or MSN Search.

  Hello Sniper167, thanks for the answer, however, I meant capturing the screen programatically so that the application will capture the current screen.

  As you are writing a managed (/CLR) app, you need to add user32.lib to your linker settings under properties: Configuration properties - Linker - Input - Additional Dependencies, so you should make it say:

  $(NoInherit) user32.lib

  or just

  user32.lib

  if it's already blank to begin with. 

  Also make sure your app under Configuration Properties - General is set to "Common Language Runtime Support /clr" and not "Pure MSIL Common Language Runtime Support (/clr:pure)"

  I just tested with a default wizard generated app, and it worked (I went into mspaint and the screen was in the clipboard, and I could paste it in).
