GetWindowRect Reference in C#, VB.NET and VB6


Visual Basic 6 definition
Declare Function GetWindowRect Lib "user32.dll" (ByVal hwnd As Long, lpRect As RECT) As Long

Visual Basic .NET definition
Declare Function GetWindowRect Lib "user32" (ByVal hwnd As Integer, ByRef lpRect As RECT) As Integer

C# definition
[DllImport("user32")] public static extern int GetWindowRect(int hwnd, ref RECT lpRect)


Platforms: Win 32s, Win 95/98, Win NT GetWindowRect reads the size and position of a window. This information is put into the variable passed as lpRect. The rectangle receives the coordinates of the upper-left and lower-right corners of the window. If the window is past one of the edges of the screen, the values will reflect that (for example, if the left edge of a window is off the screen, the rectangle's .Left property will be negative). The function returns 0 if an error occured, or 1 if successful. GetWindowRect Retrieves the dimensions of the bounding rectangle of the specified window. System.Windows.Forms.Form.Bounds
