• Visual C++ Microsoft Dynamic Link Libraries (dlls) - What ones must be given to the end user?

  Compiler: Visual Studio.NET 2002 Hi everyone, You will probably think I am a bit dim for asking this question but it is one that does confuse me. How do I know what standard Microsoft dlls (Dynamic Link Libraries) must be sent out with my software so Windows users (even the previous Windows release users) can use my programs I was going to link statically (as I got the impression that doing so would automatically put the dll in the final executable). Then I got some errors which got resolved when I linked dynamically instead. So even though the optimal answer would be to link statically, please answer assuming I link dynamica ...Show All

• Visual Studio Express Editions problem installing vb express

  It wont install! It says that its installing components for it, but when it has about 3 bars left, it doesnt go any further than that.

• Windows Forms Filelist in listbox - How to open in default editor (for any extension type)

  Hi,   I was wondering if someone could point me in the right direction for opening a file in it's "default" editor when double clicked in a listbox. I know how to catch the event, but not sure how to know which application to launch.

• Visual Studio Team System questions on iterations/classifications

  First I understand conceptually what iterations are - I've read the MSF documentation - I think it fits quite well with what we're doing... My question is do iterations show up anywhere other than as fields in work items   Are they anything more than query criteria Do they play a role in source control - for example let's say we're stabilizing an iteration for QA or something, but some developers want to continue with development into the next iteration - is there anything akin to associating changesets with the iteration Or am I barking up the wrong tree - is that the function of a branch Looks pretty cool so far - keep it coming ...Show All

• Visual Studio Team System WebTest playback where form enctype="multipart/form-data"

  Hi. I've been having some issues with the replay of a webtests that submit a form having enctype="multipart/form-data". The web test recording tool seems to deal with it just fine, and all the expected actions are performed, however when played back in VS2k5 the scripts generated application errors (i.e not VS tool errors) In our case we removed the enctype attribute and all was fine except we couldn't upload attachments (we were lucky that this was not essential). Something I noticed was the lack of Content Type Header when there was no file attached. I'm no guru on the intricacies of form submission, but I was expecti ...Show All
