• How to implement Chord function using GDIplus?

  - by leo4ever

  Here are the GDI functions Chord() provided by MFC: BOOL Chord( int x1, int y1, int x2, int y2, int x3, int y3, int x4, int y4 ); BOOL Chord( LPCRECT lpRect, POINT ptStart, POINT ptEnd ); It seems to me that no such method is privided by GDI+ (the Graphics class), so how do I implement my own Chord function (with the exact same prototype) ? By the way, I just don't understand why does MS just don't provide them. Thanks.

• Calling a function when a scrollbar appears in an IFrame

  - by chris

  I got an IFrame, in the onload event i set the height of the frame: function resizeFrame() { $("#iframeID").height($("#iframeID").contents().find("body").outerHeight(true)); } Problem is: When the content of the frame is increasing without a postback (javascript or Async Postback with Ajax), a scrollbar appears. I found a solution for Firefox: document.getElementById("iframeID").contentWindow.addEventListener("overflow", resizeFrame, false); But i can't find a solution for IE 7+8 Anyone got an idea?

• Is return an operator or a function?

  - by eSKay

  This is too basic I think, but how do both of these work? return true; // 1 and return (true); // 2 Similar: sizeof, exit My guess: If return was a function, 1 would be erroneous.
