coredll is for smart devices, not desktop Windows. Therefore, this information only applies to code using the .NET Compact Framework. To see if information for GetCapture in other DLLs exists, click on Find References to the right.

.
Summary
Retrieve a handle to the window that has captured mouse/stylus input.

C# Signature:

[DllImport("coredll.dll")]
static extern IntPtr GetCapture();

VB .NET Signature:

Declare Function GetCapture Lib "coredll.dll" () As IntPtr

User-Defined Types:

Tips & Tricks:

You can use GetCapture in conjunction with SetCapture to obtain the window handle of a Control. See the sample code below.

Sample Code:

public IntPtr GetHWnd(Control ctrl)
{
   IntPtr hOldWnd = GetCapture();
   ctrl.Capture = true;
   IntPtr hWnd = GetCapture();
   ctrl.Capture = false;
   SetCapture(hOldWnd);
   return hWnd;
}


This is a way of getting a 'dialog' window on PocketPC

{

private const int RequiredWidth = 200;

private const int RequiredHeight = 148;

private void Form_Load(object sender, System.EventArgs e)

{

    this.Capture = true;
    IntPtr hWnd = GetCapture();

    SetWindowPos(hWnd,
        hWnd,
        (Screen.PrimaryScreen.Bounds.Width-RequiredWidth)/2,
        30,
        RequiredWidth,
        RequiredHeight,
        0);
    }

[DllImport("coredll.dll")]

static extern IntPtr GetCapture();

[DllImport("coredll.dll")]

static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X,

    int Y, int cx, int cy, uint uFlags);

}
