在Windows Mobile联系人中扩展上下文菜单

我找到了另一个 example 我想这个对你有用

// Initialize the below code snippet in the beginning of the class
internal struct SHRGINFO
{
public int cbSize;
public IntPtr hwndClient;
public int ptDownX;
public int ptDownY;
public SHRGFLags dwFlags;
}

[Flags]
internal enum SHRGFLags
{
SHRG_RETURNCMD = 0x00000001,
SHRG_NOTIFYPARENT = 0x00000002,
SHRG_LONGDELAY = 0x00000008,
SHRG_NOANIMATION = 0x00000010,
}
[DllImport("aygshell")]
extern private static int SHRecognizeGesture(ref SHRGINFO shr);

[DllImport("coredll.dll", SetLastError = true)]
public static extern IntPtr GetActiveWindow();


//call the showContMenu() method in Mouseup or MouseDown event
public void showContMenu(int x, int y)
{
SHRGINFO shr = new SHRGINFO();
shr.cbSize = Marshal.SizeOf(typeof(SHRGINFO));
shr.dwFlags = SHRGFLags.SHRG_RETURNCMD;
shr.ptDownX = x;
shr.ptDownY = y;
shr.hwndClient = GetActiveWindow();

int ret = SHRecognizeGesture(ref shr);

if (ret == 1000)
contextMenu1.Show(this, new System.Drawing.Point(x, y));

}
