• SQL Server SQL 2005 Express slow/stalling

  Hi All, I've read a few threads on problems that look similar to my issue, but I can't seem to find a solution. Is there any particular reason a queries should take longer than normal to execute And I don't just mean a couple of seconds... Some times a query can take about 0.01 seconds to execute (which is good) and others it takes 25 seconds to execute (which is bad). This anomaly seems to occur on all websites using the database instance. The only thing I can think of is something to do with the server running as a Windows user as opposed to System. The user (system.mssql) has no special rights except for log on as service, plus all the normal (modify) permissions on the SQL-related directories. If anybody could give me a ...Show All

• Visual Basic How add code to the close button (title bar)

  I'd like to display a msgbox when the user clicks the close button (X) at the title bar. An option to the user is to save data or not. I tried to use the event .disposed, but the frame was already closed before the msgbox is shown. This will work, but it would be more 'fancy' if the form was still visible. Is there any form event for the close button Thanks Where are you looking for this specific event This is the BaseClass event: you probably need the FormClosing (or FormClosed ) event - unless there is some specific reason you need the baseclass Closing event. In which case, yes, you would have to handle (code) it manually. ...Show All

• .NET Development Countdown Timer

  I can't figure out how to make a timer countdown rather than counting up, I know that it has to do with System::DateTime::Subtract. I have a DateTimePicker, and I want the timer to start right when you change the value of the DateTimePicker, and I want the countdown to be counting down from the value I choose. For example if I choose August 14, 2006 on the dateTimePicker, I want the timer to be counting down from that date. Yeah that's what I thought too but I'm pretty sure I did it wrong because I got a bunch of errors. In fact I know that I did it wrong but I don't know how to do it right. If u could, would u please show me an example of what u think it should be ...Show All

• Visual Basic How do I search the database for data and return a True or false?

  I am trying to add code to check if the information in the first two TextBoxes(FirstName and LastName) is already in the database(so that I can just update it) or if the TextBoxes contain new names so that it will continue to add a new DataRow......

• .NET Development jscript event handler

  I have an existing html page that works well in a Visual Studio 1.2 ASP.Net project. When I included the page in a Visual Studio 2.0 web application I recieved errors on all my event handlers. The code I used for the event handlers is from Microsoft's MSDN site for embedding media player in a web application. When I visted MSDN and searched for jscript event handlers for mediaplayer I got the same stuff as below. Code: <script language = "jscript" for "Player" event = "PlayStateChange(NewState)"> </script> Visual Studio underlines script, for and event in red. When I hover the mouse pointer over each I receive the following error messages. script - Validation ...Show All

• Windows Forms Help required with understanding threading

  I've got a function in my program that's made by this logic: SaveItem if CheckSave = true then if Status != 5 then If Revision = "Y" or Status != 0 then SaveRSFiles else bSucces = true end if if bSucces = true then SaveMaItem end if end if Now I noticed that somethimes the application hangs on saversfiles. So I read a little bit about threading and now is my question how can I implement threading into my application Something like this: SaveItem if CheckSave = true then if Status != 5 then If Revision = "Y" or Status != 0 then SaveRSFiles (IN A NEW THREAD) else bSucces = true end if end if If thread finishes, then it needs to fire "SaveMaItem" (if bSuc ...Show All

• Visual C# Is there such a thing as a multidimensional Arraylist or List? If so. Syntax?

  Hi! I'm new to C# (and programming for that matter), so this might be a really dumb question. I want to create a multidimensional array where each item is an arraylist. I have a bunch of data, that fits different criteria, and I want to be able to store these in different rows of a multidimensional array. New data, for each criteria, is being generated, so I need the arrays to be able to resize. What I would like to be able to do is something along the lines of this: List<double>[,] myData = new List<double>[2,2]; Meaning a 2x2 array, containing in each element a List<double>. And then I should be able to add data by a statement like: myData[0,0].Add(moreData); And retrieve data by: myData[0,0][someI ...Show All

• Visual Studio Team System MS Project versions?

  Does MS Project have some sort of versioning mechanism An .mpp was created by pulling work items for a query and then saved to a desktop. after modifying and saving the changes, upon reopening the start date and first item in the project plan have incorrect dates. Once the document was sent to me and everything connected to TFS, the dates were what they should have been. I'm just curious how I can access the same .mpp and see different dates than a coworker for the same work items. We are both running MS Office Project Pro with SP2 and are both connecting to the same TFS site.
