Thank you to read it~ I want to Know use Re****ting of Team build(TFS2008) in VB 6.0. After search this, I know that basically MS not sup****t about that. But I found it is possible. http://www.codeplex.com/TFSGuide/Wiki/View.aspx?title=Chapter%207%20-%20Team%20Build%20Explained&referringTitle=Home In this link, I found about that. Building Microsoft Visual Basic® 6.0 applications. Team Build does not sup****t Visual Basic 6.0 applications by default. Use a custom post-build step to compile the Visual Basic 6.0 application. To see a similar post build step that can be used to compile a .NET 1.1 applications, see Nagaraju’s blog entry at http://blogs.msdn.com/nagarajp/archive/2005/10/26/485368.aspx or see “MSBuild task to build VB6” at http://freetodev.spaces.live.com/blog/cns!EC3C8F2028D842D5!261.entry. But it is not work...... If anyone who Know about that, please help me~.
