Programming Tips - MSVC++: Flat look dialogs / embed a manifest

Date: 2010apr27 Updated: 2023mar27 OS: Windows Product: MSVC Keywords: flat, Aero Q. MSVC++: Flat look dialogs / embed a manifest A. Starting with Vista manifests have two purposes (that I know of):
- Turning on the flat look of the controls - Turning on elevated security for your program when UAC is enabled
The manifest usually lives in a file called <YourProgram>.exe.manifest in the same folder as your .cpp files. For flat look make it contain this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity version="" processorArchitecture="X86" name="[YourProgamHumanName]" type="win32" /> <!-- the <description> tag is required but you don't have to fill it out --> <description></description> <!-- for flat dialogs add this ... Usually you DO want this --> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="" processorArchitecture="X86" publicKeyToken="6595b64144ccf1df" language="*" /> </dependentAssembly> </dependency> <!-- for elevated permissions add this... Usually you do NOT want this --> <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3"> <security> <requestedPrivileges> <requestedExecutionLevel level="requireAdministrator" uiAccess="false"/> </requestedPrivileges> </security> </trustInfo> </assembly>
Here's how you embed it in your program. In Microsoft Visual C++ 2005 and later add it as add would a .cpp file (under "Source Files") and it will be correctly embedded when you build. In Borland C++ 5.02 open your .rc (resource) file in a text editor and paste in:
#define RT_MANIFEST 24 #define APP_MANIFEST 1 APP_MANIFEST RT_MANIFEST <YourProgram>.exe.manifest
and build. It would be nice to be able to embed a manifest in a DLL. Eg make your DLL use flat-look when invoked by a older EXE (that doesn't have a manifest). You can embed a manifest in a DLL but my experiments have shown that its ignored. Maybe because the common controls are already initialized by the time the DLL is called? In VC++ 2005 and later you add this to a .cpp file for flat controls
#pragma comment(linker,"\"/manifestdependency:type='win32' \ name='Microsoft.Windows.Common-Controls' version='' \ processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"")
This doesn't require an extra file but then if you use an extra file it will be easier to edit and syntax-highlighted.
