C#

<br />
IntPtr hInstance = System.Runtime.InteropServices.Marshal.GetHINSTANCE(<br />
     typeof(ClassThatHasYourHInstance).Module <br />
);<br />

Parameters
    m 
        The module whose HInstance is desired. 
Return Value
    The HInstance for m;-1 if the module does not have an HInstance.

Remarks
    Whether dynamic or in-memory, modules do not have an HInstance.

Thanks for the suggestion, but i determined what my
error was.  I defined my RECT structure incorrectly so
that when it was being passed from managed to
unmanaged code, it was being marshalled incorrectly.

The correct definition of RECT:
[StructLayout(LayoutKind.Explicit)]
	public struct RECT 
	{
		[FieldOffset(0)] public int left;
		[FieldOffset(4)] public int top;
		[FieldOffset(8)] public int right;
		[FieldOffset(12)] public int bottom;

		public RECT(int left, int top, int right, int
bottom) 
		{
			this.left = left;
			this.top = top;
			this.right = right;
			this.bottom = bottom;
		}
}

public bool OurFunction (out object value2)
{
   bool value; //return value;

   //do whatever...

   if (value)
      value2 = "This object returned true!!!";
   else
      value2 = new string [] {"This object", "returned", "true", "!!!"};

   return value;
}

public object OurFunction2 ()
{
   bool value;
   object value2;

   // do whatever...

  if (value)
      value2 = "This object returned true!!!";
   else
      value2 = new string [] {"This object", "returned", "true", "!!!"};

   return value2;
}

public void MainFunction ()
{
   object obj = this.OurFunction2 ();
   if (obj.GetType () == typeof (string)) //true
      Console.WriteLine ("TRUE!!!")
   else // false...
      Console.WriteLine ("FALSE!!!");
}
