• Warwick Jaensch Static class decalarion and access

  First I know this post mentions windows forms but it isnt really a windows forms question I just use this as an example. It is a general c++ question for which I have other uses if there is a solution. I want to declare a class to keep track of certain values. I guessed the way to do this was with static members.

• DFive Batch Build Broken

  Re Visual Studio 2005 Standard: I'm testing with a large project (240 components), and I found that parallel builds don't work from the Batch Build box, no matter what setting I use (1-32) for the number of builds. Oddly enough, parallel builds worked fine in Beta 2, and they still work if I choose to build a "solution." When I do a batch build, however, I'm back to one CL process at a time. This same project took 3 minutes to build in Beta 2. I ...Show All
