Hello, I am trying to call GetTextOut from C#, and am having problems.  When the code below runs, only the first character is drawn, and I eventually get a stack exception:

ArrayList oWidths = _getCharSpacing( p_hDC, sOutput, p_iMaxWidth, bIsMulti );
IntPtr hPtr = Marshal.AllocHGlobal( oWidths.Count );

for( int iIndex = 0; iIndex < oWidths.Count; iIndex++ )
{
   Marshal.WriteInt32( hPtr, iIndex, (int)oWidths[iIndex] );
}

// ExtTextOut declared as IntPtr, int, int, int, IntPtr, string, int, IntPtr
GDI.ExtTextOut( p_hDC, oRect.Left, oRect.Top, 0, IntPtr.Zero, sOutput, sOutput.Length, hPtr );

Marshal.FreeHGlobal( hPtr );

Can anyone out there help me?

Thanks in advance,

- Ken
