• Visual C# C# 2005 ignoring STAThread attribute

  Greetings. I'm developing a WinForms-driven application, and I need it to use Single Threaded model for COM interop. C# 2003 worked fine with [STAThread] attribute above main() declaration. But we just upgraded our machines to VS 2005, and our application is failing due COM errors. We found C# 2005 is creating the main thread as Multithreading model, regardless the STA attribute. Any idea why is this happening . Here is a snippet of our entry point code, not complex at all. Putting a breakpoint in the first line of main(), already shows the System.Threading.Thread.CurrentThread.ApartmentState as System.Threading.ApartmentState.MTA. #region Main /// <summary> /// The main entry point for the applica ...Show All

• Windows Forms Can't disable a button

  I am programming in c#. I have a button on my form that when clicked, it plays a wav file using the PlaySound method from winmm.dll. The wav is about 3 seconds long. The problem is that if I keep clicking the button during the 3 seconds the sound is playing, it queues all of the clicks, and plays the wav over and over. My Button is named btn. So I tried: this.btn.Enabled = false; PlaySound(...); this.btn.Enabled = true; Doing this successfully greyed out the button while the sound is playing, but it still accepts clicks, so it didn't fix my original problem. Is there some way to clear the event queue Or is there something else I'm doing wrong. I just want the button to not work while the sound is playing. I have also tried ...Show All

• .NET Development When to use ExecuteScalar???

  Can anyone send me some links on ExecuteScalar or tell me when is it good to use this method.....I know it returns a single element but i dont understand the context of how it just retrieves a single element Well I guess say if you executed a query which returns 1 row and 1 column of data, or you have several columns but only want 1 column of the first row of data (saying this would also be bad practice), then it would be something you would use it for. So for example I could have a query (simple query nothing too complicated) which would return me some calculation: SELECT 4 + 3 AS 'Results' would return me 7 in the column name "Results" - this would be one way of using the ExecuteScaler method I ...Show All

• SQL Server sys.Conversation_Endpoints

  I know that if a conversation is normally ended the handle will wind up in the sys.Conversation_endpoints table in a Closed State. I realize they are supposed to stay there for 30 minutes to prevent a reply attack, however the number of rows I have in this table continues to grow with the bulk of the states set to 'Closed'. I am trying to use this table to determine if I have any conversation handle leaks. I see some rows in there with a Disconnected Outbound state while some are conversing. What should I be looking for in this table and how can I know I have a problem (ie. leak). I realize that Disconnected Outbound is probably something i need to look into. Are there any other states I should be concerned with Gary ...Show All

• Visual Studio Team System Baseless Merge: Am I missing something?

  Step 1:  I create a branch from _Trunk called _Branch1 and check it in Step 2:  I make a small change to a file in _Branch1 (changeset 10) and check it in Step 3:  I create a branch from _Trunk called _Branch2 and check it in Now, I would like to merge the changes I had already performed on _Branch1 into _Branch2. Since they are not directly related, I know I must perform a baseless merge. I use this command: tf merge /version:C10~C10 /baseless "C:\TFS\Product\branches\_Branch1" "C:\TFS\Product\branches\_Branch2" /recursive The conflict dialog pops up with the file that I changed.  Good.  I click on "Resolve..." and the "resolve version conflict" dialog box shows up.  Good.  I choose t ...Show All

• .NET Development Strongly-typed dataset, primary key generated from tableAdapter.Update(ds) not passed to FK of related table

  I have created a strongly typed dataset (CustomerDataset) with, for this scenario, 4 tables: Customer (CustomerID is PK) Account (AccountID is PK, CustomerID is FK) Invoice (InvoiceID is PK, AccountID is FK) AccountTransaction (AccountTransactionID is PK, InvoiceID is FK) Given that I am going to create a new Invoice row, consisting of all AccountTransaction rows that up until now had a null InvoiceID (i.e. transactions not yet invoiced).

• Visual Studio Tools for Office Outlook Addon - MessageBox not displaying in the current active window.

  I have created an Outlook add on which performs actions when the ItemSend mail event occurs. I have a confirm dialog box that pops up. 1) If the e-mail message is open on my secondary monitor the messagebox will display on monitor 1. 2) If the e-mail message is open on my primary monitor the messagebox will be displayed BEHIND the message window. I suspect the problem is that I need to pass the MessageBox the parent window to be displayed in. Just I don't know how to go about doing that. At the moment all I have is: MessageBox.Show("Hello World"); Thanks. Hi, I tried out the code and still not having any luck. My application is in C# so I converted the code to that.

• Windows Search Technologies How to index .xaml files for content

  Hi, How can I enable the xml filter or even the plain text filter for .xaml files I have WDS beta installed. I want to set "file contents and properties" index setting for .xaml files. I tried to change the setting for .xaml files in the advanced settings area but my change does not persist. When I close the advanced settings dialog box the setting is not changed. Hello Ahmed, The 3.0 beta 2 should be indexing .xml files by default. If you do not have the beta 2, but instead have the beta preview I would suggest upgrading. Beta 2 is much more stable and has a UI to work with. To change indexing properties with 3.0 beta 2 you should right click on the magnifying glass in the system tray ...Show All
