1. Create a Manifest File
Microsoft has introduced a new type of resource called Manifest. Well, technically it's not a type of resource; it is just an XML file included to the app as a custom resource with ID=1, which describes the application and its dependencies. If an executable file contains this resource, Windows XP will identify it and force the application to use the specific versions of libraries. Our goal is to enforce usage of new Windows Common Controls library (version 6).
Here is an example of a simple manifest file that I've used to solve this task:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"><assemblyIdentity version="1.0.0.0" processorArchitecture="X86" name="Microsoft.Windows.YourApplication" type="win32"/><description>YourApplication</description><dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0" processorArchitecture="X86" publicKeyToken="6595b64144ccf1df" language="*" /> </dependentAssembly></dependency></assembly>Create a file with its contents as shown above in the project resources folder (res by default). Replace YourApplication with an appropriate name. That should do it for our case. For further information about manifest files, see the MSDN for Visual Studio .NET.
2. Add a Resource to the .rc File
First, let's add two lines to the resource.h file. Just copy and paste the following:
#define IDR_MANIFEST 1#define RT_MANIFEST 24Now, open the application custom resource file. Usually, it's located in the res directory; the default extention is .rc2. Manually add the following line:
// Add manually edited resources here...IDR_MANIFEST RT_MANIFEST MOVEABLE PURE "res\\ApplicationManifestXMLFile"Replace ApplicationManifestXMLFile with the actual file name.
3. Modify the InitInstance Method
It's really simple. Just copy and paste two calls at the beginning of the InitInstance method:
BOOL MoneyApp::InitInstance(){ InitCommonControls(); // initialize common control library CWinApp::InitInstance(); // call parent class method#ifdef _AFXDLL Enable3dControls(); // Call this when using MFC in a // shared DLL#else Enable3dControlsStatic(); // Call this when linking to MFC // statically#endif // the rest of the code}
