• Visual Studio 2008 (Pre-release) ChannelFactory.Close() throws CommunicationException error

  Hi, I've created an intermediate service that accepts a message on a one-way contract from a client and then forwards the message onto a server based on a message header entry. The service contract for the intermediate service requires sessions and the binding uses wsHttpBinding with reliableSession set to true. When I receive a message from the client and then create a channel factory to forward the message to the server, when I close the channel factory I get the error: 'The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be used for communication because it is in the Faulted state.'. void IOneWaySessionRelayService.RelayMessage(Message message) { // Find ultimate receiver endpoint Ulti ...Show All

• Visual Studio 2008 (Pre-release) Two questions about IQueryable<T> - Expression{get;} and CS0310

  Dear group - I am prototyping a Linq provider for Mysql and have some questions. 1) The first point of entry on my IQueryable implementation is "Expression {get; }". I saw in Hartmut Maennel 's Linq provider for RDF that he returns a ConstExpression. I copied that, and it works. But what is the meaning of that Is that documented anywhere 2). My second question is more of a basic question about generics. I have my generic class, MySqlProvider<T>, and it calls into other generic classes. I get error CS0310 because the outer class can be anything, and one of the inner generic classes calls 'new()'. Code snippet below. The question - how can I cast for a 'newable' class to prevent CS0310 Thanks, George public class MysqlLinqP ...Show All

• .NET Development string.Split() method memory management - potential problems ??

  Hi friends, I've been using the string.Split(Char []) method to split two strings and compare them item-by-item. You may assume that I don't need to simply compare the entire strings (for out-of-scope reasons). The MSDN documentation says this about this method - The Split methods allocate memory for the return value array object and a String object for each array element. If managing memory allocation is critical in your application, consider using the IndexOfAny method, and optionally the Compare method, to locate a substring within a string. Does this mean that even if my array, in which I hold the split-string, goes out of scope the memory allocated by Split is still occupied and garbage collector does not free it ...Show All

• Windows Forms Typed DataSet and CommandTimeOut

  How I can define CommandTimeOut to typed dataset thanks. I build a Typed DataSEt (in VS2005), it containg a query, this query is from a store procedure that return too many rows. When I want view the preview from this query or I run this program, It give me the follow error "time out expired". The question is: How I can define the commandTimeOut to this query . I can't see any option or parameter for set it in the typed dataset. I extended the dataset class and set the commandTimeOut but I think that this not is the best way. Thanks again. ...Show All

• Software Development for Windows Vista Web Service Host - CookieContainer Property

  Hello everybody, I just read an article where Israel Hilerio posted the example " Deploy Distributed Business Processes With Windows Workflow And Web Services ". It works all fine and I think this is a very good example. But I do not really understand how the WorkflowInstance is stored when he wrote the following lines of code: string workflowInstanceId = this .ListBox1.SelectedValue; System.Net. Cookie cookie = new System.Net. Cookie (cookeyKey, workflowInstanceId, "/" , "localhost" ); cookie.Expires = DateTime .Now.AddMonths(1); cookie.Value = workflowInstanceId; ws.CookieContainer.Add(cookie); I read that a HttpModul inside the Web Service stores the actual Workflow ID in the Http ...Show All

• Windows Forms Dialog form is hidden sometimes

  Hello all. In my application I have some form that I show modally. DialogForm frm = new DialogForm(); frm.ShowDialog(); So what's happening sometimes.... frm is "hiding" before the main applciation form. And it looks like that application is frozen (its because frm is active now but does not have focus). Is it a bug in .Net If you open that dialog from a method of your main form, pass the this pointer as parameter to ShowDialog. That makes it modal to your main app. -- SvenC ...Show All

• Visual C# Problem: The breakpoint will not currently be hit. No symbols have been loaded for this document

  Hi, I've run into a problem that seems to defy a solution. Bottom line: When I'm attempting to debug with VS 2005, I cannot set an effective breakpoint in one of the source files. The breakpoint is the hollowed-out reddish/yellow circle, and VS says that the breakpoint won't work because the symbols are not loaded. I've found several discussions in this forum about this type of problem, but there's no concensus that I could find on how to solve the problem. Some background might be in order. I have been developing a "data binder" for use in a forms UI application that has multiple threads. There are three projects/classes in the solution, one for a test mainline, using forms, one for a general-purpose "dump" routi ...Show All

• Visual Studio TextEditor: How to Regain Edit Position upon window reactivate

  Is there a way to ensure that when the window regains focus the previous cursor position is regained instead of the cursor position changing to where clicked I only want the position to change if the window already has focus (is active). Example: Cursor is at EOL on line 6. I click into some tool window and no longer see a cursor position in the text edit window. Bad already. But even worse is: When I click back into the text editor window - line 15 then my cursor is there at line 15. It should go back to line 6 where I left off. THEN if I click again on line 15 it should go there. -Marc- That is what I am asking for help to do. When the TextEditor looses ActiveWindow ...Show All
