• Visual Studio Team System Problems with build type configurations and 'Publish'

  If I want to build 2 solutions in one build type, each with a different configuration, I just make sure that both of the configurations are defined in tfsbuild.proj. Then the build will attempt all four permutations (sln1, config1;sln1, config2;sln2, config1;sln2, config2) but skip the ones that are not valid for each solution, is that correct   Also when I try to publish, I would expect it to do a build first, or do I have to be exp ...Show All

  A while back I installed Visual Studio 2005 Team Suite Beta 2 Version on my laptop and used it. I now have the latest Visual Studio 2005 Professional and I want to install it but I can't.

• SQL Server Datatype conversion strangeness

  Hi all, After more headbanging and cursing than an entire Metallica audience, I have finally deduced how to store and calculate the values of a stack storing RPN calculations using a recursive stored procedure. But there is a new conundrum. Originally, to test the above, I was using fairly simple values -- 10, 20, +, 3, /, etc. But the real data is likely to include values with at least a couple of decimal places -- these have been configured us ...Show All

• Visual Basic strange bracket problem

  Hi, I've been finding that randomly, after building my project, the editor will start inserting brackets as I type. For example: I type "a" - it changes to "a()" I type "try" - it changes to "t(r)y" I type "ng.Save" - "n(g).s(a)ve" I've disabled Edit and Continue, but still have the problem. The only way to get round it is to restart visual studio. I've had the problem on two computers, ...Show All

• SQL Server Using variables of Connection Manager, Connectionstring

  Hello, I'll spare everyone my diatribe about MS and Booksonline... I considered myself pretty good at Server 2000 DTS.

There are two books out so far. one is poor, the other worthless. What I want to do seems very simple. That is to loop through a series of .txt file ...Show All

• .NET Development Loading external assemblies that are not strongly named

  Hi,   I have a project which references an assembly that is external to the application (it is not in the bin directory of the project or in a path relative to the application).     At runtime I use reflection to load the assembly from a supplied path.   The exception ‘System.IO.FileNotFoundException’ gets thrown.     The external assembly is not strongly named and so I cannot use the ‘codebase’ ...Show All
