  Hi, I have two tables in my database, Orders and OrdersId and are laid out as following: Orders OrdersId ------- ---------- OrderId (comp key) OrderId (PK) LineId (comp key) RepId ProductCode CustId ProductPrice ProductQuantity The OrderId field in table OrdersId is the primary key, whereas the Orders table has a composite key (OrderId and LineId). I need to add a row of purchased item data data into both tables but am not sure how.

• Game Technologies: DirectX, XNA, XACT, etc. Sprite is not transparent

  Ok I finally got the game to work but I have a new problem...my texture which I made transparent in DirectX, doesn't have the transparent background when I run it. Is this due to my graphics card & me adding that line of code to make the program work Sorry I can't remember the exact line but it's been floating around the forums, I think we all know what it is. Did you add in the AlphaBlend when you begin drawing your sprite That parameter was missing from the original tutorial. //Clear the graphic devices (set background color) graphics.GraphicsDevice.Clear(Color.CornflowerBlue); graphics.GraphicsDevice.BeginScene(); //Begin drawing the scene. Using AlphaBlend as the blend mode ...Show All

• Windows Forms SDK - CertMgr.exe

  Hello, I found this MSDN article which talks about calling certmgr.exe to automate adding certificates on the client work stations. http://msdn.microsoft.com/library/en-us/dnwinforms/html/clickoncetrustpub.asp frame=true But I find that CertMgr.exe is a part of the SDK and not just the framework redistributable. So how does one automate the task of installing the trusted publisher and Certifying Authority certificate TIA Avinash ...Show All

• .NET Development Is this a bug , any one can tell me?

  I found a bug when I am programing: when I use like this: " ".IndexOf(" ") is returns -1,when it should return 9; but " ".IndexOf(' ') is OK. and belows all worked well: " ".IndexOf(" "); " ".IndexOf(" "); " ".IndexOf(" "); My environment is : Windows XP SP2(English Edition + Mutil-Language Pack) + .NET Framework v2.0.50727+Visual Studio 2005 PS: It works well in javascript. Actually, it is entirely by design. The trailing character at the end of the string is U+ff9e, a.k.a. HALFWIDTH KATAKANA VOICED SOUND MARK. It is treated as a diacritic attached to the preceeding character, and as such it modifies it's identity, the sama way that a latin letter plus a diacritic is not equal ...Show All

  If in a Key_down event I want to ensure that the data that goes into the listbox is only numeric do I use a If then statement   I would like it so that if the user input alphanumerica data my program will show a message box say it must be numeric and then reset the textbox to empty and put my focus back on the text box   I tried the following code but I get the error message "must be numeric" even when the key pressed is numeric Private Sub TextBox1_KeyDown( ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown a = TextBox1.Text If Not IsNumeric(TextBox1.Text) Then MessageBox.Show( "Must be numeric value Text Box 1" ) TextBox1.Text = "" Te ...Show All

Following the advice on: http://msdn2.microsoft.com/en-us/library/yah0tcw1.aspx I inherited from class Control http://msdn2.microsoft.com/en-us/library/system.windows.forms.control.aspx My control will require two distinct and cooperative transparent items.

• SQL Server Comparing millions of records from file A and B

  I'm trying to compare about 28 million records (270 length) from table A and B using the Lookup task as described in this forum. The process works fine with about two million records or so on my desktop ( p.4 3.39GHz, 1.5 GB Ram), but hangs with the amount of data I'm trying to process. I tried using full and partial caching, but to no avail. I'm thinking this is a hardware resource problem. So, does anyone has any recommendation on the hardware needed for this kind of operation and/or suggestion Thanks in advance...

• Architecture How to prevent Service Control Manager from writing to the Event log

  I am using the SCM calls like CreateService(), StartService() to dynamically load a driver. What I found was everytime I load the driver I get a eventlog message saying "The XXXX service was successfully sent a start control" I presumed one of the paramenters passed on to CreateService() or StartService() would prevent that message, apparently not. Question is how do we prevent this SCM message from getting logged in the event log Any help will be much appreciated thanks ananda ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Screen layout for 360 games

  Dave made a blog entry yesterday pointing to another blog entry that should be a must-read for all of us considering doing 360 development. I know I had no idea about what he talks about. Terry A. King wrote: Interesting article, safe areas are one thing but how do we treat different resolutions on the 360 Spacewar was written for a 1280x720 screen which is probably the default size for HDTV if using the AV cable. If you're using a VGA connector though you've got all these resolutions available to you : 640×480, 848×480, 1024×768, 1280×720, 1280×768, 1280×1024, 1360×768, and 1920×1080.

• Game Technologies: DirectX, XNA, XACT, etc. Setting texture wrap mode for SpriteBatch

  I can't find any means of settings texture wrap mode except by using an shader which has no effect on SpriteBatch. Also I couldn't find a means of declaring a custom vertex def with transormed coordinates but I admit to not looking real hard for that one yet. If I could that then I could just write my own sprite engine with full effect support. I read a post suggesting effects for SpriteBatches in the release version and I would like to second that. That would solve this little wrap problem real quick like. Other than that XNA has been a good experience so far. Still just a few days into it. I'm porting a long running and ever evolving 3D puzzle/action game from vc++ and with the exception of a few structural changes in the code its bee ...Show All

• Visual Studio 2008 (Pre-release) DataBinding - Converter - how to refresh the view?

  Hi All, I am trying to create a WPF app without using code behind (all the UI element will bind to the data by databinding). And this is the scenario, I have a list of Orders, each Order has a OrderStatus, so my Order object will have an order status id, to show the data on the view (tree view), I have to show the status name. I created a converter to convert id to name. But how can my tree view automatically refresh when a status name changed Thanks, VS When we generate groups, it's a one-time thing. For V1, we don't monitor the property on which you group to handle the change. You can always call Refresh on the associated CollectionView to get the groups to change. ...Show All
