Compiler error from setting icon

[TGF]

Hello,

When I attempt to set the icon property on a Windows form (.NET), when I
go to compile, I get the following error....

e:\Projects\MyApp\AboutForm.h(108): error C2039: 'GetObjectA' : is not a
member of 'System::Resources::ResourceManager'

....Does anyone know why this happens, and the way to correct it....I looked
up the function member "GetObject", and it is a valid member function. Note
that this error occurs in the InitializeComponent() function where the VS
code generator says not to edit it. So what gives?

...Does anyone know why this happens,
Because GetObject is #defined to GetObjectA in WinGDI.h, so the
preprocessor replaces your call to ResourceManager::GetObject with
ResourceManager::GetObjectA.
and the way to correct it....

You can #undef the GetObject macro, or if possible avoid to #include
Windows.h altogether.

Mattias,

In the header file where the problem occurs, I have no <windows.h>
included, or any other header file for that matter. I do however, have the
following namespaces included...

using namespace System;
using namespace System::Threading;
using namespace System::ComponentModel;
using namespace System::Collections;
using namespace System::Windows::Forms;
using namespace System::Data;
using namespace System::Drawing;
using namespace System::IO;
using namespace System::Resources;
using namespace Microsoft::Win32;
using namespace System::Collections::Specialized;

Perhaps your header file is included in some other source file where
windows.h is used?

or any other header file for that matter.

Well, the GetObject macro must be defined somehow. You can always try
to just #undef GetObject before the call to
ResourceManager::GetObject.
