I've just converted a VS2003 application to VS2005, and a PInvoke call to
AdjustWindowRect which apparently worked fine in VS2003 is pulling a runtime
error under VS 2005, as follows:

A call to PInvoke function
'Graphics!DSC.Utilities.Graphics.Win32RECT::AdjustWindowRect' has unbalanced

match the unmanaged target signature. Check that the calling convention and

My declaration for AdjustWindowRect looks like this:

[DllImport("user32.dll", EntryPoint="AdjustWindowRect")]
 public static extern bool AdjustWindowRect(ref Win32RECT clientCorners,
ulong dwStyle, bool bMenu);

my Win32RECT struct, which is impersonating a Windows API RECT struct looks
