MFC42.DLL in .NET Apps
-
When I compile my application using VC++ 6.0, my app requres MFC42.DLL while if compiled with VC++.net, is requires MFC70.DLL Is there a way to compile using .net AND forcing it to link to MFC42.DLL and not MFC70.DLL ??? PLEASE help. Rick Eastes. ------------
The MFC in VC7 is version 7, that's why the EXE uses mfc70.dll. --Mike-- Just released - RightClick-Encrypt v1.4 - Adds fast & easy file encryption to Explorer My really out-of-date homepage Sonork-100.19012 Acid_Helm

Obviously. However, the .net framework (20MB) is certainly not small. I don't want to distribute this dll when mfc42.dll would be fine. Rick Eastes. ------------

You should just be able to distribute the MFC7 dlls. The .NET framework is only required for managed applications. Michael :-) Time flies like an arrow. Fruit flies like a banana

mscvp70.dllWhat they are saying is that redistribuing DLLs is wrong and obstrusive to the new XP install procedure. You must distribute what they call Merge modules (.msm files). Btw, .mcm is a subformat of the general Windows Installer SDK (.msi database). Otherwise it won't install on XP, depending on the profile. Have fun.:~ And if you still want to distribute sharewares on a low deployment basis (for 9x for instance), just distribute these : mfc70.dll msvcr70.dll msvcp70.dll (stl) msvci70.dll I recommend to put these files in the app directory, not on system32.

Well Daniel I believe you're right, at least in theory, But in practice I have had so many problems with statically linked MFCs, especially when I tried to run my .exe on someone else machine with sometimes another OS, that I have decided that static linking of the MFCs was not for me. The problem was most of the time a crude GPF! (memory access violation). In fact, the only *good reason* not to put the MFCs in your app directory is that the MFCs are not only DLLs, they are COM components, and self-register themselves each time they are loaded, hence overwriting the registry, which may lead to unpredictable consequences on the stability of other installed MFC apps, especially after uninstall.

My MFC application compiles successfully in both VC++7.0 and VC++6.0 but I feel I have wasted my time and money buying VC++7.0 WHY? I need to have a small distributable. Here are two senarios: 1. Compile with .NET Need MFC70.dll which most computers don't have. 2. Compile with VC6 Runs on ALL computers without ANY additional dll's :mad:Surely there is a way using .NET to make the exe link to old dll's like MFC42.DLL and not new ones like MFC70.DLL Rick Eastes. ------------ http://www.eastes.net

The problem was most of the time a crude GPF! (memory access violation). I've never had a problem with statically linking. Perhaps you wrote some bad code?

Yikes! I still suspect that isn't true, but I greped the mfc dlls and mfc42.dll has DllRegisterServer in it. Thankfully none of the MFC70.dll's have that in there so maybe they've changed things.

Yes, somewhat waste of money especially if you don't have C# in the package you bought. What's more is that MFC70 has STL embedded everywhere, much harder to debug a callstack than the previous release IMHO. For some programmers however, MFC70 is a new step to achieve robustness and so on,

This isn't true: 1. MFC dlls are not COM components. You can't regsvr32 mfc70.dll. (But you can create COM components with MFC). 2. COM components doesn't register themselves each time they are loaded. 3. With a COM DLL, it doesn't help installing the DLL on your app directory, because, when registered, it will be the only one DLL to be instantiated. Concussus surgo. When struck I rise.
