[DllImport("user32.dll")]
static extern bool ValidateRect(IntPtr hWnd, ref RECT lpRect);
Public Declare Function ValidateRect Lib "User32" (ByVal hWnd As IntPtr, ByRef lpRect As RECT) As Boolean
Public Declare Function ValidateRect Lib "User32" (ByVal hWnd As IntPtr, ByRef lpRect As IntPtr) As Boolean
Public Shared Function ValidateRect(ByVal hWnd As IntPtr, ByVal lpRect As System.Drawing.Rectangle) As Boolean
Return ValidateRect(hWnd, RECT.FromRectangle(lpRect))
End Function
None.
In the Win32 API, it is valid to specify a value of "NULL" to lpRect. I am not sure how or if you can specify null structure references using pInvoke in C#/.NET.
You can specify the lpRect param as null if you define your function as you can see bellow:
[DllImport("user32.dll")]
static extern bool ValidateRect(IntPtr hWnd, IntPtr lpRect);
Please add some!
Do you know one? Please contribute it!
