• Visual C# IDE changes the .csproj file <SubType> between UserControl and Component

  When any file in my project is changed, I have one UserControl that the IDE changes the .csproj file <SubType> between UserControl and Component. This happens even if the UserControl is not changed. Is there any way to stop the IDE from changing this Hello all, I think another user has hit on the "answer" to this issue here: http://www.pcreview.co.uk/forums/showpost.php p=3645831&postcount=5 The IDE seems to get confused if there is more than one class defined in the user control source code file. Moving your extra classes (besides the one inheriting from UserControl) to separate files seems to "solve" the issue. I was having this problem, and a quick test s ...Show All

  I have a few activities in parallel that listen for the same event. With the event arguments I will see which one of the parallel activities to execute. It seems though that the event is only fired in the first activity and not in all the activities waiting for this event to fire. When you have another workflow loaded that does not have a parallel activity in the workflow the event now fire twice in the same event handler. I will not know before runtime what workflow I will be executing. ...Show All

If you have to keep entire image in memory, then you have to choose another platform with more memory or you have to reduce size of image, that’s pretty much all your options. There’s a lot Windows Mobile devices can do, but processing huge images in not one of these things. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. NoSuitableGraphicsDeviceException was unhandled

  Let me just say at the outset that I know nothing about C# (yet) and am trialing the XNA beta to try and get into it. I do know VB and some C, however. Once I had everything installed, I tried a few example programs including the Spacewar project, but I cannot run any of them. They build fine, but I can't run the .exe, and it crashes and asks if I want to send a report to MS. If I "Start Debugging" instead, I get the error "NoSuitableGraphicsDeviceException was unhandled" on the "this.GameComponents.Add(this.graphics);" line. I have no idea where to even start.

• SQL Server query to Linksed server very slow!

  Hello, i have created an RPC from my SQL server which queries a database of a linked server (remote server). the query result is very very slow. (it is a mis-size query, with many JOINs on tables with many entries). Let's say it takes about two minutes to get about 3000 results. The query uses five tables in the database of the linked server, runs a few (let's about 5-8) JOIN clauses and selects the entries. except for two tables (out of 8), each table has about 1000-2000 entries. the two have about 40,000 entries. Is this normal ! Is there anyway i can optimize my query i also tested my query and asked for only 100 results as opposed to all of the 3000. there was only 2-3 second difference in getting the results back, which indicates that ...Show All

• Visual Studio 2008 (Pre-release) Client state after FaultException

  Hi, I have the following situation: After the client gets a FaultException using a HTTP binding the clients state remains Opened. After the client gets a FaultException using a TCP binding the clients state changes to Faulted, and it is rendered useless! Why is the behavior different depending on the protocol of the binding Can I avoid this problem when I'm using TCP or do I have to recreate the client Sincerely Herbjorn So, what you should do is always check the state of the proxy after catching an exception. If it is faulted, a new session is required, and you must reconstruct the proxy. Just a question: how do I check the state of a client proxy The proxy itself does only contain those functions I added t ...Show All
