Hi,
I've been trying use the GetThemeColor function from the uxTheme.dll in a C#
app...but i can't seen to get a valid result? Could someone tell me what I'm
doing wrong here??

[DllImport("uxTheme.dll", EntryPoint="GetThemeColor", SetLastError=true,
CharSet = CharSet.Auto, ExactSpelling = true,
CallingConvention = CallingConvention.Winapi)]
private extern static System.IntPtr getThemeColor ( System.IntPtr hTheme,
int partID,
int stateID,
int propID,
out int color);

public Drawing.Color GetThemeColor ( IntPtr hTheme, int partID, int stateID,
int propID )
{
int color;
IntPtr retVal;

retVal = VisualStyles.getThemeColor ( hTheme, partID, stateID, propID, out
color );
if ( System.Runtime.InteropServices.Marshal.GetLastWin32Error () > 0 )
 throw new Exception(
System.Runtime.InteropServices.Marshal.GetLastWin32Error().ToString() );

if ( retVal.ToInt32() > 0 )
{
 return Drawing.ColorTranslator.FromWin32 ( color );
}
else
 return Drawing.Color.Empty;
}

Thanks for the assist!
