• Visual Studio 2008 (Pre-release) Problem looping trough IEnumerable of QueryResult

  Hello I have a strange effect and wonder if someone can explain me what can cause this. var q = from  a in b ...<fetchs something from database>.... System.Collections. IEnumerable e = q.Take(q.Count()); List<MyType> l = new List<MyType>(); foreach ( object  o in e )     l.Add((MyType)o); The foreach gets executed one time (one object in the list) and then an EmptySequenceException is thrown.

• Visual Basic Tab Control Problems in Beta 2

  It seems that the Alignment Property for the TabControl in Visual Basic in Beta 2 has problems. If you want the Tab Pages, tabs to be on the Left or Right side of a form, they will appear once set in the designer. But, any TEXT you put on the tabs is missing. With the Tabs set to TOP the text appears normally.  There is no errors raised or anything. Just no text. Have I missed something here I looked and tried several other settings and there is nothing in the Tab Page Collection that allows the text to appear vertically as it would need to be if the tabs are set for Left or Right.  james   ...Show All

  Hello - I am performing a load test using a few recorded web test scripts. The built in counters are great - but I would like to also use custom counters that are on remote servers.

• SQL Server Alternate Synchronisation Partners

  Yes, I know synchronisation to alternate partners is deprecated in SQL2005 but.... In SQL2000 there is a Sync Partners tab in the publication properties dialog that allows you tick a checkbox for each co-publisher to be enabled as an alternate synchronisation partner. What is the equivalent in SQL2005 I've set up replication in SQL2000 following these instructions http://support.microsoft.com/ kbid=321176 and it works. Now I'm trying to do the same thing in SQL2005 but I can't find a substitute for steps 10 & 11 in the section "Set Up the Alternate Synchronisation Partner". What's the answer Thanks in advance. ...Show All

• Windows Forms Bug in "Installation Folder" user interface dialog of setup project

  It seems that there is one bug in Setup project Installation Folder dialog. If you delete the text from the Folder Text box the Next button is not disabled. If you continue as it is then setup installs the files in default location. Is there any work around to resolve this bug The problem is that in Windows Installer based UI there is no event sent when you edit the content of an edit box, so you cannot immediately disable the Next button. As a workaround you would have to verify the content when the user clicks the Next button and diaplay an error message if the property which is associated with the e ...Show All
