Board index » Visual Studio » How to use MFC 4.2 with Visual Studio .Net

Visual Studio255
Hi! I have recently started using Visual Studio .Net in place of Visual

Studio 6.0. My application is an Active X control written in C++ with MFC

4.2.



Is there a way I can force Visual Studio to use MFC 4.2 and not MFC 7.0,

since the application will be deployed mostly on systems with MFC 4.2.



I know I can use "static linking" but that will make the application large

and I am still adamant on using 4.2 libraries rather than 7.0 to be safe.



Any suggestions.



Thanks in advance for your help.

This question has started coming up a lot. The answer is simple: revert to VS6. It is

absolutely silly to think that an MFC library designed for one compiler will work with

another. Microsoft got away with it for years by a sneaky renaming: making MFC42-for-VS5

(and VS5 programs would not work with MFC42-for-VS4.2), MFC42-for-VS6 (and VS6 programs

would not work with earlier versions of MFC42), and the assorted service packs also made

forward-compatible but not backward-compatible changes (that is, programs from earlier

compilers worked with newer MFC42 versions, but programs from newer compilers would not

necessarily work with older versions of MFC42). VS7 is a significant departure from the

old style MFC (e.g., CString is now a completely different implementation to allow for

Unicode CStrings) and MFC42 has been abandoned. MFC70 is what is delivered, and MFC70 is

what you will use.



Don't trust static linking. That MFC70 requires other DLLs, which you are supposed to also

deploy, be consistent with MFC70 and each other. Just abandon the myth (it has been a myth

for well over a decade) that "copy == install" and use a proper installer! Then there is

absolutely NO problem "deploying" VS .NET programs on any platform. All you have to do to

make it possible is do the job RIGHT.
