• Visual FoxPro MySQL and VFP

  Hi experts. I have a MySQL database. I operate with them using syntax like SQL(sqlhandle, "select * from...") I copy them into cursor and than operate with a cursor. Is there a simplier way how to work with them Thanks in an advice. I understand but I have asked whether the problem may be that I am using free MySQL database, whether this speed isue can be one of the database limits. the code below takes somethimes 0,61seconds and sometimes up to few seconds(1-3) start=SECONDS() OPEN DATABASE data mySQLhandle=SQLCONNECT("connection") end=SECONDS() WAIT WINDOW end-start the code below takes 1325.436seconds to complete (10 000 records) start=SECONDS() FOR i=1 TO 10000 SQLEXEC(mySQLhandle,"INS ...Show All

• .NET Development Sticky SqlCommand session

  Hi all, After executing a SqlCommand, and closing its' connection, and even manually disposing everything off... sp_who still says that the session is there, untill I close the whole application. It's a Big deal: because of the locking i'm creating in that SqlCommand, that never release... untill i close the application. how can get rid of the SqlCommand session and does this relates to connection pooling ...

• Game Technologies: DirectX, XNA, XACT, etc. fx Shader files do not support more than 1 technique?

  I found some strange bug in the Effect class (I think), maybe this was mentioned before, but I couldn't find any information on this. I wrote some simple shaders for line rendering (see more details and fx source code on my blog). If I put each technique in a own file, I can access the shader technique passes with: effect.Techniques[0].Passes But if I put 2 techniques into 1 fx file only the first one works. If I access the second one either by calling effect.Technique[1] or effect.Technique["NameOfTechnique .."] it still accesses the first technique. I'm pretty sure this is not a user error on my side because if I have only 1 pass in technique 1 and 2 passes in technique 2, the app crashes if I try to access the 2nd pass in the ...Show All

• Visual C++ executing a member function in a separate thread

  hello everybody !! my new problem is that i have a class that contain a some functions and some variables i want to execute one of these functions in a separate thread using AfxBeginThread(...); and FYI this function uses some member variables of the class to do it's work any idea thnx 4 ur time and concern a.hemdan Creating a new thread will not be your main concern.

• Game Technologies: DirectX, XNA, XACT, etc. Orthographic UI

  So...in OpenGL I would use glOrtho(0,1,1,0,0,1) before processing my UI draw calls to set up my screen to be: 0,0 . . 0,1 . . 1,0 . . 1,1 that way, I could tell a UI component to be at 0.1, and it would make it so at any aspect ratio, any resolution, that UI component would always draw 10% to the left of the side of the screen. I want to do something similar to the UI system I'm working on for XNA, but I'm not sure how to setup the XNA camera to switch to an Orthographic projection before I process my UI components using the sprite batch.

• Visual C# nonserialization of events

  I know how to do it ie [field:NonSerialize] , but I do not understand why I need specify the field: attribute target. Incidentally it works fine, but finding it was not easy - I found it in the ECMA Language Specification, not a particularly easy read, later I found it in an MSDN article. But they do not explain the "why", just the "what". And, how can I access, via Reflection, attributes with a specific target. When I get the custom attributes for an event with the [field:NonSerialzed] attribute via the EventInfo.GetCustomAttributes method it is not reported. Nor can I figure how to access an event's underlying "field"; unlike a methods return value which is available from MethodInfo and or MethodBase (I for ...Show All

• Visual Studio Team System How to make the webtest use unique values in different runs from data source

  Hi, I have a web test and it pulls data from a table. My requirement is that the web test should use each of the rows in the table only once. i.e if I execute the webtest once, it pulls the first row.

• SQL Server SQL Server Management Studio Reports "Column Prefix" errors on fields such as [First.Name] and [Last.Name]

  Hello, I have an existing SQL 2000 database that I am now accessing from SQL Server Management Studio. In the past, I've created specific tables using dot notation within the field names. I've used Enterprise Manager to edit and update these specific tables without problems.
