• .NET Development Generic Synchronized Collection?

  Hey, I was just wondering if a Generic Synchronized Collection exists I know with an arraylist you can do: ArrayList arrayList = ArrayList .Synchronized ( new ArrayList ( ) ); And with generics I usually use the List class, which is not thread safe. I see on the MSDN website their is a SynchronizedCollection class, but I cannot see to make it work. (I cant create an instance) and the article does not seem complete http://msdn2.microsoft.com/en-us/library/ms668265.aspx Any suggestions SynchronizedCollection only exists in .NET 3.0. The generic classes of .NET 2.0 do not include synchronization because MS decided (correctly) that including synchronization into low-level classes was not appropriate, beca ...Show All

• Windows Forms Inserting Text in RichTextBox

  How can you insert text into a RichTextBox control richTextBox1->Text->Insert(0,"Hello"); //This doesn't throw an error, but it doesn't do anything either .NET2.0 richTextBox->Text is a property accessor for a string and then you call the Insert method on that string instance, which returns a string, but you do nothing with the result of that function... richTextBox1->Text = richTextBox1->Text->Insert(0, "Hello"); ...Show All

• Visual Studio 2008 (Pre-release) No appropriate XAML tags for inline code

  According to the documentation (...), in an XAML document one can have inline code which contains, say, C# code for event handlers. Is it possible to insert such code in an XAML created with Visual Studio If yes, what is the correct tag which should contain the CDATA element In the articles that I consulted, either <def:Code> or <x:Code> is used; however, these tags always generate errors when I try to compile the project. This is what I did: - I created a new project (WPF or XAML browser); - in the XAML editor, I added some controls - say, a <Button>; - I added a handler for the button, with ' Click="OnClick" ' - I wanted to have the code of the handler in the XAML file. For this I tried to ...Show All

• Visual Basic insert snippet with a shortcut key

  I write in VB.Net with VS2005. I would like to insert my code snippet with a single shortcut key. It's so inconvenient for me to insert a code snippet every time according to the following steps: 1. right click on my VB codes 2. click the "Insert Snippet..." menu item from the context menu 3. find and select the folder of the snippet I would like to use 4. find the snippet I would like to use from the selected folder The above 4 steps is too long to me. What I want is a single shortcut key for each insertion action. I considered to record a macro for this. However, I found out that I could not pop up the context menu for the "Insert Snippet..." menu item once I have started marco recording. How can I insert my code snippet in a faster way ...Show All

• SQL Server Execute As error

  I have a stored procedure that needs to run with elevated privliges, so I tried setting it to run as one of the db owners. When a regular user tries to execute the SP, I get the error Cannot execute as the database principal because the principal "joejoe" does not exist, this type of principal cannot be impersonated, or you do not have permission. What do I need to set up so a user can be impersonated Did you try as SELF It should work like you want. mpswaim is a user, who is the db_owner group, right You really shouldn't need impersonation for this procedure to work anyhow, since all users have rights to sysprocesses. Here is the script I used to reproduce the situation. I created the users without login for e ...Show All

• SQL Server Accessing Variables in SSIS code

  Hi I am not able to access SSIS variables which are defined at Data Flow Task in a custom component. This custom component is developed by me in C#. How can i access these variables Please let me know if theres a way to access SSIS variables. Thanks, Vipul Custom data flow components, also known as pipeline components, inherit from the PipelineComponent class. This exposes a public read-only property called VariableDispenser, so you can access this in your own methiods, or those you override from the base class, PipelineComponent.

• Community Chat Some neat things about Vista.

    I'm not using the Vista Start menu. I am using someone elses and it didn't come with Help. (I think I know why) Vista's new help engine is called Helppane.exe and simply starting it up doesn't bring up help. In looking into this I discovered that the taskmanager displays somethings that it didn't used to. For example it display command lines for processes that just started up. I start the normal Vista Start button and select Help and when it came up I noticced that the command line was Helppane.exe -embedding All I had to do then was a add that to the link and I now have help. Does anyone else have any interesting Vista tips. I think we'll stat to see a lot more interest this week. I've lost so much work beca ...Show All

• Visual C# Can't start my Windows Service

  Hi... I've got something which is making me pull my hair out which I hope someone can shed some light on. Basically I've got a Windows Service using VS.NET 2005. This service has been working fine for a while. For some reason now, I cannot get the service to start. By placing MessageBoxes in (with the correct display permissions) I found that the service itself is just not 'activating'. (Main and OnStart are not being called) So I cannot even attach to the process to debug. The service startup manager times out with Error 2186. 'The Service is not Responding to the Control Function.' All permissions within the directory appear OK. I've treid uninstalling/reinstalling. I'm not sure whether this is a .NET 2.0 issue or not.
