• Visual Studio Visual Studio .Net 2005 Beta 2 - can't access MSDN

  Just installed VS 2005 Beta 2, it's great.  Like the new features. Unfortunately, I can't seem to access any help system.  The only help I get is "help on help".  Nothing on MSDN or VC#.  Tried reinstalling MSDN and that didn't help. Has anyone else experienced the same problem   Or is it just me   For what it's worth, here's another manifestation of the same problem. In my case I can neither access the help from the IDE nor from the Start menu; I get an apparently empty help collection in the IDE and a failed load ("Microsoft Document Explorer can't access help collection...") ...Show All

• Visual Studio Max number of sourcesafe database?

  Dear experts, For easy management, our company want to set the visual sourcesafe to each project own a database. So, is there a max number of database can be created in visual sourcesafe and visual sourcesafe should support simultaneously running multiple database, am I right Finally, would numerous databases (say over 40) deteriorate the performance much Thanks all. Yes, VSS supports multiple databases. There is no max number of databases you can create. The databases are just files/folders stored on Windows file shares, and VSS only track the database location through strings stored in registry so the performance do ...Show All

• Visual C# how do I do this? (sorting)

  Hi. I feel terrible asking this but i cannot figure it out. I think my mind is all over the place.   OK, I will be reading elements from an XML file. File has "Start Time" which has h:m:s and "End time" which has h:m:s What I want to do is sort the start time in order. Sure, I could put them in an arraylist then call the sort method, but I want to match the start time with the end time sorting in the start time order. any ideas/thoughts Well, what you did is also a good solution. You could also create a SorteList (it's an IDictionary) and add StartTime as key and your object as value. So the list is automatically ...Show All

• Visual Basic Datagridview bound to empty table, esc edit fails on first row?

  Trying to understand how the Datagridview control works, I have bounded it to an empty table. If I begin edit of any field in the top row and "esc" the edit on this fisrt row I get an unhandled exception message "Current cell cannot be set to an invisible cell". My guess is, the control is trying to move to the row above the top row which, obviously, it should not. This occurs even if I do not have any code wathsoever in the events of that grid. Where do I handle this error Is this something that is happening on my box only or can this error be reproduced easily by others Of course, in many occasions, the tab ...Show All

• Visual Studio 2008 (Pre-release) What causes CommandBinding.CanExecute delegate to be invoked ?

  I have a button that executes a command when it's clicked. I have a CommandBinding instance associated to that command, and also methods to: * Allow/disallow execution * Preview execution * Handle execution All 3 are being called. It's obvious when the last 2 will be called but not the first one. Depending on a specific application state, my CanExecute method will return true or false. When the application starts it returns false which makes the button is disabled, as I expected. As the application runs, its state is changed, but the button is still disabled because it didn't call CanExecute to get the new value. What's strange is that when ...Show All

• Visual Studio Team System Incredibly (astronimically) slow performance on new RC of TFS

  We upgraded from beta3 to RC on TFS. Also ran the 2.0 hotfix. I uninstalled the client (had no instances of vs2k5 running) and installed the new RC team explorer client. I also installed the 2.0 hotfix on my local computer. Now the SQL server runs on 100% load.. 'TfsVersionControl.dbo.prc_QueryItemsExtendedLocal;1' is running It loads the solution fine to a certain point, but then freezes. Getting latest from team explorer goes fine. Branching is successful, opening the branch, however, was not successful. It resulted in the same kind of freeze / cosmic slowness. On 1 out of 10 times, I managed to load the solution. From there it was fa ...Show All

• SQL Server Connection Pooling

  I am using SQL 2000 and am trying to use sp_setapprole to set up user access. I am also using VB.NET with the MS Patterns and Practices Data Application Library for the database connection. I have discovered that connection pooling has to be set OFF for this SP to work. My question is this: If I have set connection pooling to OFF to run sp_setapprole, can I then set it back to ON and still run in the same session To explain a little more: Application starts Windows Authentication is used to grant access to a User table Connection Pooling set to OFF Application sets the users role with sp_setapprole Connection Pooling set to ON Data access i ...Show All
