Hi "epdti",
Can you go into a little more detail on exactly what you mean? Do you mean that:
1. You want to use Visual Studio to write applications in Java and Python?
2. You have tools (presumably that can be invoked as executables from the command prompt) you've written using Java and Python that need to be invoked by Visual Studio either at design or build time?
If the answer is #1, then I would suggest checking out
http://www.visualstudiogallery.com/ for extensions that support building applications with Visual Studio using these languages.
If the answer is #2, then this is certainly possible, although you'll need to be creative in how you host these tools. The very simplest way would be to write a
MSBuild ToolTask which would know how to invoke your tool on the command line.
Please let us know how it goes and if you had something else in mind.
Thanks,
Aaron
