I would like to update some toolbar-like code we have to have a Vista/Win7 gradient roundedness to them. Currently, the buttons have the Windows 2000 look & feel: blocky, single-tone. I've played around with the XP themes, and using DrawThemeBackground, DrawThemeEdge, etc.; but I'm very dissatisfied with the theme drawing mechanics (th...
In my Windows CE DLL project, I am trying to tell Visual C++ to link statically to MFC in a project that originally did not use MFC. However, upon linking successfully, Dependency Walker (depends.exe) says that my DLL is dynamically linked to MFC80U.DLL and MSVCR90.DLL. Has anyone else encountered this bug? If "Use of MFC" is set to "Us...

Hello, I generated a DLL in Visual from a C++ code. Dependency Walker sees 3 functions exported as C functions. I made an SCons project to do the generate the DLL, and 2 of the 3 functions are not seen as C functions. What makes a function seen as a or C++ function, without modifying the code ?

Visual Studio projects assumes all files belonging to the project are situated in the same directory as the project file, or one underneath it. For a particular project (in the non-Visual Studio sense) this is not what I want. I want to store the MSVC-specific files in another folder, because there might be other ways to build the appli...

You've got to be kidding me... surely there is an add-on or a plug-in to the VS2008 resource editor to make it work correctly with high color bitmaps? This just seems insane. How are al...
