• Visual Studio Express Editions Managing exceptions in a backgroundworker

  Hi, I'm using a backgroundworker (in VSE2005 for C#) and have the following problem : In the 'dowork' method I have a try/catch that handles exceptions that might occur and then rethrow them for the 'workcompleted' method have a proper error state. The problem is that when an exception occurs, I get an unhandled exception error message pointing to the 'throw ex;' in the catch block (see code below), because of course ex is not being handled, at least not right there. The problem is that in order to test for the error status of you background _dowork method in your 'workcompleted' method you rely on the RunWorkerCompletedEventArgs ...Show All

• Visual C++ I am use visual c++ about 3 years. I found MFC is hard to learn. I want to return to pure c++. Is anybody likes as me?

  I am use visual c++ about 3 years. I found MFC is hard to learn. I want to return to pure c++. Is anybody likes as me Yes, I feel the same as the original poster. I wonder if it ever occured to Microsoft that most of us have to develop projects to make a living and don't have the time anymore to invest months into studying new languages, new frameworks and new paradigms In our company we made the decision to continue using C++ and MFC. Frankly we're just using MSVC 8 in order to have easy access to native 64 bit compilation. Other than that, you could take all C# and .Net and whatnot and trash it. ...Show All

• Visual Studio Team System Setup cannot access Reporting Server

  Hi there, i'm trying to install the Team Foundation Server. When setup asked me to enter a user for the Report Server. I created a user TFSReport and added him to Administrator-group and all the sql-groups. I opened the Report-Server Configuration and configured it so that the TFSReport-User controls the service (works without any errors). Near to the end of the setup, i get the following error, that setup cannot access the SQL Report server. I should ensure that it is installed, that it runs and that i can access it. Any idea Thanks in advance, David I think I narrowed the problem down. The command that ...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

• Visual Studio Debugger Hangs Delay Notification

  The problem happens while debugging when I try look at the details of "this". It happens every time. In the "Locals" pane I try to expand the entry "this" by clicking on the "+". I get an internal error after which Visual Studio won't do anything else and pops up a dialog named "Delay Notification" when ever I try to interact with it. I must use task manager to exit it. I was having the same problem when I first installed Visual Studio Beta 2. I found there were some assemblies left behind from Beta 1 and I manually removed them. It didn't fix the problem, so I uninstalled Beta 2 and then ran the clean up tool to make sure there weren't ...Show All

• Visual Studio Team System TF30144 error when creating a project from another domain

  Hi I am struggling with a setup which consists of TFS single deployed on domain X and Team Foundation Client (and Visual Studio) on domain Y. X and Y does not know about each other since they are on diffrent nets and the DNS servers are not connected. My first problem, which I solved, was that TFS setup (or possibly SharePoint Services or SQL Server) uses computer names in configuration files. Thus, Team Explorer did not work correctly (red crosses on the documents and reports folders etc..) since computer names couldn't be looked up from domain Y. This was solved by adding the IP computer name mapping in the Windows 'hosts' file. &nbs ...Show All
