The algorithm would be something like: Do while every file has been validated Readfile Validatefile Loop My problems are : How can I get every file name and path individually, so I could open them one by one How can I get the number of files sellected by the user Thanks! Very helpfull! Thanks (its cool to have people answering in forums when you are alone to learn all that stuff... ) ...Show All

• Visual Studio Team System QueryHistory and invalid dates

  I am trying to call QueryHistory to get all changesets between two dates. I am passing a start date that is before the TFS server was set up, ie it should be invalid. I am trapping for DateVersionSpecBeforeBeginningOfRepositoryException during this call. However, the call itself does not throw an exception. It's only when I try to enumerate through the changesets in a separate client app that this exception is thrown. This seems like wierd behaviour. Shouldn't the QueryHistory throw this exception Or I am doing something wrong Here's my code: System.Collections.IEnumerable changesets = null; try { changesets = versionControl.QueryHistory(baseFolder, VersionSpec.ParseSingleSpec(startDateString, null), 0, ...Show All

• Visual C# C# to C++ Migration Difficulty?

  I am currently learning C# mainly for the interests of learning an object orientated language early (I'm only 15), but also since the announcement that XNA games can be made for the Xbox 360 I'm interested in that as well. Since the games industry uses C++ in their games and I'm aiming for a career in either video game programming or just programming in general, how easy is it to adapt to C++ from C#, Or are there no significant changes in structure, syntax etc Hello All. mts2325: Well, the short answer is : Not nearly as easy as going the other way! Going from C++ to C#, there are quite a few things that you don't have to worry about anymore. Conversely, going from C# to C++, there are a lot of things that you have to wor ...Show All

• Visual Studio Tools for Office Data validation code embedded thru .Net Program

All the above steps will be developed in a .NET program written with VB.NET.
