• .NET Development MSMQ Serializable Hashtable subclass causes a hang when extracting Message.Body

  To start:   I get no error message; just a hang condition.   If I could get an Exception, I could probably figure this out for myself.   Instead, .NET just hangs, cold and unresponsive.   Here's the short concept of what I'm doing (no code examples here as the concept should be simple enough to implement by any interested troubleshooters): Make a struct called KeyValuePair with two fields:   a Key and a Value, both String types.   Mark the KeyValuePair struct as [Serializable]. Make a subclass of Hashtable called HashSet and override the Add method to guarantee that all Keys are unique at a ...Show All

• SQL Server Making SSAS Developer Edition act like standard edition

  My understanding is that the Developer Edition of SQL/SSAS contain all of the functionality of the Enterprise Edition. Is there a way to force it to act as if it were Standard Edition (and therefore subject to all of the limitations of SE) The reason I ask is that with our product we're trying to maintain compatibility with both SE and EE. I realize I can just install SE instead of DE, but if there's a way to simple toggle the behavior, that would be even better (especially since I already have DE installed. :) A partial answer: If you have a BI project (that you open with Visual Studio to design and t ...Show All

• Visual Studio Express Editions Problems installing Visual C++: install hangs & 100% cpu

  I meet or exceed the system requirements: WinXP SP2 Over 3GHz Processor Pentium 4 w/HT (not sure if you need to know this or not) 1GB RAM 50GB available hard drive space I already had the .NET framework installed, so I uninstalled it as directed, and rebooted my computer.

The processor usages shoots to 100%. Trying to kill the process closes the little install window with that last message, but the program continutes to run.

• Visual Studio Nested Solution Folder Parent?

  I am creating an unbound reference. In my IsEnabledFor method I am trying to see if the current item is a SolutionFolder, and if so, if its parent is also a SolutionFolder with a specified name. For some reason, I can get to the logical parent of the current solution node, as it is in Solution Explorer. I can easily test if the target is a SolutionFolder, but the problem is testing its parent. Project project = (Project)target. - OK project.ParentProjectItem - yields a ProjectItem for the same node project.ParentProjectItem.Object - yields the same object (SolutionFolder)(project.Object) - yields the solution folder interface (SolutionFolder ...Show All
