• SQL Server transaction has already been implicitly or explicitly committed or aborted error

  We are using MSDTC to handle our transactions and some clients seem to be getting these errors more and more when we went to framework 2.0. Any ideas what could be causing this Before in framework 1.1 we would ask our clients to re-register their computer into the domain and/or rename their computer and this worked but it seems like in framework 2.0 it doesn't do the trick. Also, the wrong dns setup causes this too but after trying to fix both things it still doesn't work. I believe this error means either the server has finished the transaction and can't find the client to return the result or the active directory account/computer accoun ...Show All

• .NET Development Datagrid asynchronous update / refresh

    I have an application with a datagrid that needs to be updated every 5 seconds. Currently, to accomplish this, I am doing this from an datagrid1.Invoke call that is based on a timer. The timer uses a callback that calls a method. That method nulls the datasource, and retreives the data into the data source and then sets the datasource property of the datagrid. The problem is, every 5 seconds, the datagrid rebinds to the datasource, and resets the selected property of the datagrid. So if the user has scrolled down into the datagrid and selected a record, it is lost. I am sure there is a better way to do this. Any help would be apprec ...Show All

• SQL Server Cannot get the Service Broker work

  Some months ago I was playing with Service Broker and everything was ok. But now I just can't get it work. I opened a sample "helloworld" project and still cannot get a message in a target queue. No errors, just empty queues. We have two SQL servers sept CTP on different computers and both give the same issue. It looks like it should have a very simple solution that I cannot come up with. The following script initializes service broker and sends a message, then selects both target and initiator queues. On my environment it just returns two empty selects. --Initializing service broker objects use master GO S ...Show All

• Visual Studio Team System Having issues with Team Build

  I'm having some issues with this Team Build. The first one was I didn't have Team Build installed, so I have a computer beside me that I just re-did with Windows XP Pro, and just put team build on it. The main issue I have right now Is I cannot delete yesterday's "team Build" i created. Nor can I edit it. When I created it, I wanted to test to see how it worked so I set it up to build on my computer. However, now I can't change it at all, nor can I delete it. I see the XML, I try to save my changes, it tells me it's write protected, so I overwrite it. My changes do not save. Can anyone tell me how to delete this Buil ...Show All

• Visual C# Thread & ProgressBar

  Ok. I know this is a wierd question. But I would like to know how to connect a progressbar to a thread. I have a download function, and when the user clicks a button, the function is a thread you could say. So basically, I would like to track the progress of the download or thread in a progressbar. Here is my thread.   Button_Click Event(Object Sender, EventArgs e) {           Thread MyThread = new MyThread(Downloader);           MyThread.Start()   } That's not at all a weird question!

• Visual Studio Team System cluster server support for DT?

  subject says it all, I think.. Is there (currently or planned) cluster server support for the DT server   I want to say the data tier supports clustering, because that tier would just be SQL Server 2005.  So you should be able to use clustering like you always do.  I believe you have to have SQL Server 2005 Standard or higher.

• Visual Studio Team System Team Explorer Beta 3 issues.

  I have 4 machines with Team Suite RC, and one machine with only the Team Foundation Client, and am running Team Foundation Server B3 (single machine install): On two RC machines, where both users are set as "Project Administrators".  In Team Explorer, the Reports folder shows "Reports (working...)" and never expands and never finishes "working".  However, these users can do Team/Show Report Site, and that works...  Further, if "Stop Refresh" is clicked on these machines, Team Explorer appears to hang.  Additional weirdness... I can get the reports to show up on these two machines, but only if I choose to disconnect fro ...Show All

• .NET Development trimming of whitespace in dataset/database

  My dataset is coming back with a bunch of whitespace in the data. i.e. my data will look like "some data      " instead of "some data" This isn't just a matter of trimming the values once they're out of the db. When go and get a dataset and ask for every row except ones containing "some data", it finds none, and thus returns everything. Depends if your DB is setup to pad the extra space in a char field or not if your not consuming the max. lengeth. Michael ...Show All
