• Visual Basic "By Design" IDE Bug

  I'm sure this has been asked (compained) about before, but I can't locate a post about it, so here goes... The IDE deletes my code without asking. I do not want it to do that. Precisely, if I want to delete any code, I will highlight it and hit the delete button. Go figure. The problem occurs when controls are cut and pasted (for example, to move from the form surface to a panel or tab). The IDE quite rudely deletes the event handlers. I understand this is 'by design', but it is infuriating to say the least... Is there a hotfix for this A hack Anything The VS2005 designer for VB.NET forms doesn't appear to do that. It leaves the event handler code but just removes the Handles keyword. Which create ...Show All

• Software Development for Windows Vista Custom Persistence and CompletedScope table

  I have just successfully completed a custom persistence service for MySQL. I have been digging into some of the other tables associated with the SQL persistence schema and stored procs. I came across the table CompletedScope. I did find a thread on it saying it is used to hold completed activites derived from ICompensatableActivity. My question is how do I add custom support for this table into my custom persistence I see no examples or discussion on this. Thanks Bill Bill, Have you ever seen when is the LoadCompletedContextActivity or the SaveCompletedContextActivity are called I'm testing the Oracle persistence service but I can't design a workflow to test those methods.

• .NET Development Error "ExecuteScalar requires an open and available connection..."

  H all, I have an application that retrieves data from a local SQL2005 (Standard edition) database frequently (e.g. more than 10 times/second normally). It usually works fine. However, if the program was paused for a while (e.g. for a few hours) by a pop-up error message box or an Sleep() statement, it generates the following error message when its data processing resumes: " ExecuteScalar requires an open and available connection. The connection's current state is closed ." The application is coded with C# using ADO.Net. The connection is OleDbConnection. It seems there is some timeout process that I do not know. Could anyone offer any hint Thanks, hz Thanks a lot for the detailed explanation, Sarah! T ...Show All

• Visual C# Return a pair of List

  Is it possible to return a pair of list objects from a method Thanks Regards Alu Say you want to return a list of strings and a list of ints, you can do this List<string> Method(out List<int> theInts) { } Now you need to assign a value to theInts in your code, and you need to return a list of strings as well. So, both are returned, although one comes in as well. ...Show All

• Windows Forms Major problem - Help

  I am not 100% sure this is where to post my problem but I suddenly got aprox. 1,000 errors to pop up. I am using Visual Studio 2005 (Visual Basic code) and SQL Server Express. I made a change in my program (a simple loop to populate a combo box with data from the server - have done it many times) and then left it alone. For about the next 5 minutes I was working on paper creating new queries for the program when suddenly Visual Studio poped up with an error message talking about the compiler and that VS 2005 needed to close. "No information will be lost". Once I said "Don't Send" to 27 popup messages I was finally able to save and close as it instructed me to do. When I reopened the program is when I noticed all of my errors. The errors ar ...Show All

• .NET Development Problems with deserialization of SOAP Response (Complex Type from Apache / PHP Webservice)

  Hi, I want to consume an Apache Webservice with a C# .NET Client. Everything works fine, but I’m having problem with the deserialization of the complex type “Item” that is included in the response of the web service, what seems so be the type “hashtable” in .NET. Every “Item” consists of two fields “key” and “value”. I read a lot about SOAP/Apache/.NET/Complex Types/etc. and somewhere I read that there is no automatic deserialization possible of such a type. Does anyone know a HowTo-Example or Codesnippet Or can somebody explain how to consume Complex Types from Apache I didn’t find any helpful postings or Code Examples… I’m looking forward to your replies!
