• Visual Studio 2008 (Pre-release) WSE 3.0 versus WCF

  i am confused about whether i should be writing our new web services in WCF or WSE 3.0. many of our CLIENT applications still run older operating systems, such as Windows 2000. do my client applications need to be running the .NET 3.0 framework to easily communicate with a WCF web service If so this means it will only run on WinXP SP 2 and Vista right If so, should I be considering WSE 3.0 instead then Or will this be getting phased out Me confused. this post here says clients need xp sp2 or vista http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=224021&SiteID=1 "As far as client-side operating systems goes, WCF requires XPSP2 or Vista." ...Show All

• SQL Server Execute multiple statements at once...

  I am not even sure if this is possible but I want to be able to excute several statements (or SPs) at once from inside a SPs (or any other method). What I am doing is a I am taking data from a single column, multiple rows and making it into one row (i.e. data1 + data2 + data3....) But I am doing this to a total of 2.1 million individual rows and the result will be about 204k rows.... what I have written is basically a nested loop and it works fine but very slow... slow as in it has been running for 24 hours now and it is about 60% done... I need this to finish in under 36 hours preferably... If I could handle more than one set of data at once (there will be no duplicates) I could speed up the process by how ever many I feel like work ...Show All

• Visual Basic How can I cycle through all the System.Drawing.Colors?

  Why do i always get this error message whenever i try to debug or compile something : "error CS2011 : Error openin response file 'c:\Documents ' -- ' the system cannot find the file specified " this is after i uninstalled and reinstalled the compiler.

• SQL Server Output values from Update Statement

  Hi, I'm using the following UPDATE statement to "check out" a record in my parent table tblTransaction where the record is not already checked out. Also, I have a details table (tblTransData) that has two records for one record in the parent table. When checking out a transaction, if a user has already modified a record in the details table, it will not check out the associated parent row. I have this working below. My issue is, how can I return the primary key value (intWorkFlow) of the row in the tblTransData table where the user has not worked on either record and the record txtUser column is NULL (indicating that no one has worked on the record) Right now, I am using a separate select statement to find the null record tha ...Show All

For the notification, I use the below: [ OperationContract ] public void Notify( NotificationMessage message) { lock (_lock) {     for ( int i = _subscribers.Count - 1; i >= 0; i-- )     {         try         {             _subscribers .ReceiveMessage(message);         }         catch ( Exception ex ) & ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Joining DirectSound to existing app

  I am trying to use DirectX DirectSound which I need to attach to an existing Windows application in order to capture a signal. Since playing sounds is easier, I decided first to attach a button to the existing application that would play a sound. The DirectX 9.0 documentation seems to have no direct tutorials in which such a function is attached to something else. I have done a fair amount of experimenting but am stuck. Specifically, (1) (this is probably trivial) I don't know how to specify the "control" variable in the method Device.SetCooperativeLevel(). (2) (apparently more serious) the instruction "dsDevice = new Device();" throws the exception "[description of instruction] is attempting managed execution insi ...Show All

• SQL Server Need to convert NULL values to 0, (zero) in order to perform math calculations

  Using a reporting services model/report builder we have two related tables: - Fundings, (parent) - Draws, (child) Report Builder reports that subtract "Total Fundings.Amount", (which is SUM(FundingAmount)) from "Total Draw Amount", (which is SUM(DrawAmount)) to get a balance work as expected except when there are no Draw rows, in which case a NULL is returned. Obviously we want to convert NULL values of "Total Draw Amount" to zero so that when subtracted from "Total Fundings.Amount" the correct value is displayed. I've searched for a function similar to COALESCE (Transact-SQL) in report builder but found nothing. Can anybody help me with this Thanks Bruce ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. How to disable driver anti-aliasing

  I need to preserve the exact colors (and thus, hard edges) when I read back the rendered image via an offscreen surface filled with GetRenderTargetData. There is an option in the control panel where the driver forces anti-aliasing for all applications. If I do not set the quality-performance slider correctly, I will get anti-aliasing. Is there a way (in code) to prevent that Eric, Have you tried setting D3DRS_MULTISAMPLEANTIALIAS = false in the SetRenderState for your device This should disable anti-aliasing for anything rendering from the device.
