• Visual Studio Visual Studio 2005 perfomance issue

  Well, i just converted my 10 project solution to VS .Net 2005, and i'm finding out the converted app is running very slow. There has been no real change(except i substituted ConfigurationSettings.AppSettings to ConfigurationManager.AppSettings to see if that was the performance issue) and no luck. My application connects to Microsoft SQL Server(not 2005). What may be the cause to this problem My computer is a 2.39GHZ Celeron pc with 752 mbs RAM. There was no problem whatsoever with 2003 though. Thanks. Hi. Just wondering - make sure you don't have any unneccesary background apps running or applications open ...Show All

• Smart Device Development trackbar question

  hi, i have a trackbar whose value is changed during the tick event of a timer. this happens while an audio file is playing. I want to be notified when the user changes the trackbar's value so that I can seek through the audio file and play the part that refers to the trackbar's value. how can I do this tapping into the ValueChanged event won't do because the value changes while the file is playing. is there a way to determine whether it is the user or the timer event that is changing the trackbar's value Please help! Thanks. You will need to cache the expected value you are setting to the trackview from you ...Show All

• Windows Forms Jet database engine/mdb file - issues?

  Hi, I have used the Jet database engine in .NET for an application in the past, and did not have any issues at all. I am working on a much bigger application, but can't see any obvious pitfalls (a few million rows perhaps is all I anticipate at worst). Moreover, this is a Windows application, so I don't have many other choices, it seems.

• SQL Server Subscription Missing

  We are seeing a problem with the users of our application. If the user closes our application from running programs (as best as we can tell as we cannot repro in dev) and SQL Mobile is in the middle of an async sync, sometimes when the application restarts it fails to load the properties for replication from the database. We are using code that is nearly identical to the samples provided by MS for performing replication async. Basically, the database still exists on the device and the application can use it just fine, but when a sync starts, the database is already there, so it tries to load the properties at which point we get a message sta ...Show All

• Windows Forms Generic ComboBox<T>???

  Is there a way to create / get a combobox that will only accept items of a specified type thereby negating the need to cast from Object I tried creating a subclass of ComboBox but that didn't seem to work as Items is a property instead of a method and is not virtual. No you can't using inheritance because even with the new modifier someone can still get access to the non-generic Items property. However if you use composition (by nesting a ComboBox in your own control class) then you can control all the access to the combo's items. The downside is that you'll have to expose any combo properties that t ...Show All

• Visual Studio Express Editions Great Performance improvements

  I'm amazed with performance improvements which is growing since beta 1 compared with VS.net 2003. I'd like to know what percentage of C# Express is written in managed code. Thanks There isn't a great way to answer your question, but core components of Visual Studio remain as native.  New features, as they are added, go through the choice of being added as a managed component or as native. Several important parts of Visual Studio, such as the server explorer, properties window, refactoring, and lots more are implemented as managed components in the shell.  ...Show All

• Visual Studio How do you Edit a Tracepoint in VS 2005?

  How do you Edit a Tracepoint in VS 2005 Clicking on it deletes the tracepoint... I note for the record that if your cursor is beyond the end of the tracepointed statement, that seleting "When Hit" will do nothing.  This is confusing - and maybe even a bug - because when the cursor is BEFORE the tracepointed statement, the right click displays the "Insert..." context menu vs. the edit an existing menu. ...Show All

  Is it possible to make an existing excel workbook into a vsto solution by adding the 2 properties _assemblyname and _assemblylocation with appropriate values Do I need to do anything else Yes.
