Question

C#.

Example:
_{(source: brianapps.net)}

I’m working on a screen capture software, so I want to enable specific window capture.

Answer 1

  mnuHandle = GetSystemMenu(hwnd, false)

  //add a line to the end
  AppendMenu(mnuHandle, MF_SEPARATOR, 0, "")

  //2 add a command ID = 200
  AppendMenu(mnuHandle, MF_STRING, 0x200, "Command &1")
  AppendMenu(mnuHandle, MF_STRING, 0x201, "Command &2")

  //insert a new item to the 2. position
  InsertMenu(mnuHandle, 2, MF_BYPOSITION, 0x202, "Command &3")

  //remove a standard item 
  RemoveMenu(mnuHandle, 0, MF_BYPOSITION)

it’s not the point to create the menu items in the system menu of a totally different application… the question is more or less how would you hook the upcoming system menu events?

If resizing an arbitrary window is what you want to do: just fetch the window handle of the program (how would you do this?) and call SetWindowPos http://msdn.microsoft.com/en-us/library/ms633545(v=VS.85).aspx
