Automatically convert Visual C++ 7.0 projects back to Visual C++ 6.0 projects.
This tool automatically converts VC++7 projects back to VC++6 projects. Without this tool, you end up recreating your projects from scratch, which is a total waste of time, and prone to errors. In this post, you will find a list of scenarios where this tool is useful. You will also find out how to use it, what is converted and technical details.

What Is This ?

This tool automatically converts Visual C++ 7.0 projects back to Visual C++ 6.0 projects. In other words, .sln/.vcproj file pairs are translated to .dsw/.dsp file pairs.

Important note, there is no loss during the conversion: source code is left unchanged; only .dsw/.dsp are created (or overwritten).

Why?

First of all, because MS doesn't provide it. It's easy to become cynical against MS when you feel how bad it is to sell developer tools without all the necessary "moulinettes" (converters in ugly English) to go backward.

Without this tool, you end up recreating your projects from scratch: a total waste of time, and prone to errors. Actually, there are several scenarios where this tool is useful:

  • Someone gives you a VC++ 7 project, and you only have VC++ 6 installed.
  • You have upgraded your project(s) from VC++ 6 to VC++ 7, and you have both .dsw/.dsp and .sln/.vcproj files on your local system drive, but you are willing to keep those files synchronized so any time you need to open the project, you need not bother the VC++ version you work with.
  • Provide both versions of projects (for instance, when you share code on CodeProject), so your audience does not need to bother with knowing which devtool is required.

How to Use It

The tool is a command line of the form:

prjconverter <solutionname (full filepath)>[.sln]

For instance:

prjconverter c:\tmp\betterxml\betterxml.sln

For info, type prjconverter.exe alone in the console.

What is Converted

A few steps to let you know how the work gets done. The .sln solution file is opened and translated to the .dsw file format, along with all project declarations, dependencies, and source control tags.

Then all .vcproj project files are translated to .dsp files. I use MSXML to parse the .vcproj file format, and build the meta-model out of it. Then what's left to do is serialize all those XML thingies into the standard .dsp symbol lines.

Of course, we care about project configurations (debug, release, ...), and custom file configuration settings.

Technical Details

In the code provided, slnprocess.cpp does the .sln =>.dsw conversion. vcprojprocess.cpp does the .vcproj => .dsp conversion. And vcprojconfiguration.cpp holds the project meta-model (all project setting tabs). In VC++ 7, the meta-model is now programmable. Let's check out this link. In fact, vcprojconfiguration.cpp reflects exactly this meta-model (as if it was internal MS code).

Disclaimer

This tool has been extensively tested before being published (MFC/COM/ATL/console apps, makefiles, ...). Though I am willing to know if there is anything I can do in order to improve it, let me clearly say that it's not my fault if your project is corrupted by this tool.

Update History

  • 27th September, 2002 - Code complete
  • 2nd October, 2002 - Now it is possible to convert .vcproj files alone (no need of a root .sln file): just type the .vcproj full path in the command line.
  • 30th October, 2002 - Improvements based on user feedback: added missing default link libraries, expanded certain macro variables such like $(OutDir) and $(IntDir), replaced or removed certain macro variables not supported by VC6 such like $(NoInherit), added /GX (exception handling enabled)
  • 13th November, 2002 - Bug fixes: filenames with spaces, MFC extension DLL support, custom precompiled header setting, project setting inheritance

I really miss the Call Graph and Callers Graph in the VC7 environment and it seems that Microsoft "did not have a time" to make it yet in VC7 - and that it will be included in the next release.
- Thanks for this tool that makes it easier to create a parallel VC6 project in order use VC6 Call/Callers graphs!
