how to cast IntPtr to struct type

[BestNews]

Hi all,
how to cast an System.IntPtr value to struct type.
Example:
protected override void WndProc(ref System.Windows. Forms.Message m)
{

const int WM_WINDOWPOSCHA NGED = 0x0047;

if(m.Msg == WM_WINDOWPOSCHA NGED)
{

string str="";

quickGetText(0,-1,ref str);

//HERE I NEED TO CAST m.LParam to WINDOWPOS struct

//WINDOWPOS wndptr = (WINDOWPOS)m.LP aram;

return;
}

base.WndProc(re f m);

}

//C++ structure declaration

[StructLayout(La youtKind.Sequen tial)]

struct WINDOWPOS

{

System.IntPtr hwnd;

System.IntPtr hwndInsertAfter ;

int x;

int y;

int cx;

int cy;

System.UInt32 flags;

}

Can any help me out.

regards
