• Game Technologies: DirectX, XNA, XACT, etc. Is XNA the tool for serious game developers.

  I'm trying to make the decision if our game development team should use XNA as the technology solution. The question is, if XNA is capabale, or is intended to be, a commercial game development tool set for serious game developers. Reviewing the majority of the posts here (XNA vs. C++/DirectX) It is a very powerful and fast development environment, however at the moment its range is limited to the Windows and Xbox 360, meaning that (at the moment ) you cannot develop as easily as you can with C++/DirectX for alternative next-gen platforms (Macintosh (hah, as if), Wii or PS3). I, however, haven't seen many remarks on the possibility to opening this to other platforms. ...Show All

• SQL Server Error during merge web sync

  Hello,    We have 5 subscribers trying to replicate via web synchronization. Two of the subscribers get the following message and the other three are fine. Any ideas on what the problem is or where to troubleshoot Thanks in advance. John Error on client output: The format of a message during Web synchronization was invalid. Ensure that replication components are properly configured at the Web server.   I have seen typically that once is 3 times you can get successes. Other times it could fail to load the dll and hance cause the sync to fail. Can you try on a different IIS box that doesnt have anything except the virtual directory to rule out this possibility ...Show All

• Visual Studio MSbuild VS 2005 AssemblyReference using enviromenent variable pointing on "subst" drive

  Hello, I'm using a " subst s: c:\Source \" to set the source code to a virtual drive, and then use s:\MyProject.vcproj, for example, in the msbuild parameters.

• SQL Server Importing Online XML file into SQL Server 2005 tables – no data transferred

  Does anyone have any great suggestions on how I can import an online XML file into an SQL 2005 table So far I tried to accomplish it with SSIS Data Flow Task where my source is XML Source (Data access mode: XML file location; XML location: URL, Use inline schema = True). This set up properly identified the columns to be imported. I used Copy Column data flow transformation task to load data to OLE DB destination table that has same structure. When I run the task it does execute with no errors, however the table remains empty. It looks like I am failing to read the actual data. Do you have any suggestions I am willing to go around this approach with stored procs/com/you name it – just make it work! ...Show All

• Smart Device Development Get and Set the position of a scroll bar of a ListBox in NETCF2

  Is it possible to set the position of a ListBox scroll bar in C#. I've inherited the ListBox class. I get a NullReferenceException when I try to do this: IEnumerator i = listBox1.Controls.GetEnumerator(); i.MoveNext(); MessageBox .Show( string .Format( "i.Current.Visible.ToString() = {0}" , (( ScrollBar )i.Current).Visible .ToString())); i.Current returns NULL. It works for a datagrid. Datagrid is a composite control written in netcf entirely. Listbox is a native control - it does not expose the scroll bar control. Normally you would set the TopIndex property to position the scroll bar ...Show All

• SQL Server Getting HelloWorld_CLR sample to work

  Hello, I have been trying to get the app installed and running; I've updated the install script to point to the right server and it worked. I've run the ALTER DATABASE ssb_HelloWorld SET ENABLE_BROKER ; and the EXEC sp_configure 'clr enabled' , 1; and the CLR seemed to have problems while getting replies back from the server. However after repeated retries it worked well. Sporadically I would see an error. After uninstalling the sample and installing it again - to document the steps previously taken - the CLR application is no longer receiving messages from the server. Any idea about what setting might be needed Thanks, Hi Rushi, After successfully sending a m ...Show All

• Visual Studio Express Editions Dates in SQL string

  Im having trouble with selecting records from my DBASE IV database with a select statement. When i try to use the statement DBRset.Open("SELECT * FROM NEWBAR WHERE DATERCVD= 29/09/2006", DBConn, ADODB.CursorTypeEnum.adOpenDynamic, ADODB.LockTypeEnum.adLockBatchOptimistic, 1); it returns no records, which it definatly should.
