• .NET Development failed to connect to an oracle 8i database

  Hello everybody, I hope someone would be able to help me… I need to programmatically talk to an Oracle 8 database located in a remote server. I have installed the client oracle 8 + Toad into my computers (Windows XP) and I have no problem connecting to this database by using toad. Then I added the System.Data.oracleClient dll to my project, imported it and tried to connect via my application, and had the ORA-12560 error. I can’t open the connection. My connection string is : “BaseName. UNIV-PARIS.COM (from the names.default_domain in the sqlnet.ora file); user id= ; password=” Have you any idea of what my problem is Thanks you for your help, Susana I thin ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. foreach slower than for on 360?

  Hi, I have been hearing on the "internets" that foreach runs slower on the XBox 360 CF because of the IEnumerators used. According to this hot book, "Effective C# (item 11)", it claims that the C# compiler 1.1+ generates different code when a foreach is used on an array. The code avoids IEnumerator and even avoids bounds check that a normal for() loop would invoke. The book, however, was written in 2004. I was hoping for a a final statement on this because I just find it hard to believe that foreach is slower on the XBox 360 and enjoy the syntax it offers. Thanks. When developing games, it is a good practice to avoid generating garbage. That is, to avoid allocating objects and then mak ...Show All

• Windows Forms HTML Editor (WYSIWYG)

  I'm looking for a HTML (text) editor for a WinForm application. Do these exist THanks for the reply Glenn, I found one yesterday in the "purgatory" section of CodeProjet. It works fine (it was written in spanish, which is why it was probably there), however there's an un-signed DLL in it (htmlEditor) and I can't figure out who wrote it... or what else it might contain so I'm not sure I want to use it for our commercial application :( I'll give the others a lookee. ...Show All

• Visual Studio Team System Test Results Grids

  I noticed in the test results grid if you right click and click add/remove columns there is a way to add fields for standard error and standard out. I was wondering what I would need to do to output results to these fields. Thank you very much. ~Todd I am not sure if this is the recommended way to do it but it does accomplish the goal. System.

• .NET Development Managed application startup time too long

  I'm going nuts - I've been developing numerous WinForms applications (managed) on VS2005/.Net Framework 2.0 now for almost one year without any problems. Now suddenly the startup time for these applications have been extended by 10-15 times - and I cannot understand why. Where the JIT previously presented the application within one second it now takes 10-15 seconds before the Main form appears on screen on the same computer. This effect takes place disregarding programmed overhead, even a simple form without any programmed body or database dependency takes this long time to start. Moved to any other computer the applications start nice and fast. I have reviewed Registry settings and all other conceivable parameters, but without posit ...Show All

• .NET Development SerialPort Class

  I have an application that uses serial communication to control a machine. When I suddenly send commands to oft, I understand that the buffer may become full and I might not be able to send anymore data. I've noticed that, because I have implemented some exception handling and I always catch a TimeOutException when I try to write to the serial port. The Timeout value must be 5 ms, due to the properties of the machine and I am not thinking about changing it. Anyways, once I catch a TimeOutException, I am not able to write to the serial port anymore, even if I repeat trying. Since the first time, the program keeps catching TimeOutExceptions undefinetely. If I restart the program, without restarting the machine, it works fine. That means, ...Show All

• Windows Forms NumericUpDown, Binding and the tab key

  I'm using .NET Framework 2, Visual Studio 2005, and Windows Vista RC1. When you type a new value in the NumericUpDown control, and then you leave the NumericUpDown by clicking another control, the NumericUpDown fires events in this order: 1. ValueChanged 2. Validating But when leaving the NumericUpDown by pressing the TAB key, events are fired backwards: 1. Validating 2. ValueChanged And with this, a Binding to the Value property, if it has DataSourceUpdateMode=OnValidation, does never update the datasource. The Binding object handles the Validating event of the control, and, if its value has changed (if the control has raised ValueChanged before), the binding writes the value to the datasource. But if ValueCha ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA with Forms

  Is it possible to use XNA graphics into a windows Form That would allow nice tools programming ... Thanks Yes, it's possible. You will want to create a GraphicsDevice object yourself, rather than using our Game and GraphicsComponent types. That way you have full control over where it gets drawn, and can pass in your own window handle when you create the device (which you get from WinForms). ...Show All

• Visual Studio Express Editions msgbox, make a word bold

  I have a message box and i want to make a single word bold. On the line belowe I want "phonestring" to be bold, is this possible The code that I have is: MsgBox( "You did not enter a correct phone number Please Enter either 10 or 7 digits only." & Environment.NewLine & "You Entered: " & phonestring & "" , , "WRONG PHONE LENGTH ERROR" ) The standard system messagebox doesnt support this as standard behaviour. You can always create your own form and split the message into a couple of different labels which would allow individual parts to be formatted differently or use some other control such as a richtextbox control on a form which would enable more speci ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. How to load textures embedded in a model file using a custom importer

  I have a Q3 BSP loader and want to build the lightmap data during the import stage, however while i can build the data into a Texture2DContent, There seems to be no way to do anything with it - the BasicMaterialContent class has a Textures collection, but seems to require an external reference to a filename. Any ideas N I did this for my rewrite of quake in XNA. I wrote a bitmap writer that save to a memorystream (or a file). So I can just use this to load them as file: Texture2D.FromFile(graphics.GraphicsDevice, ms, size); Pretty simple and fast. In my case I have to load lightmaps and Textures from the bsp based on the provided palette. ...Show All

• Smart Device Development CeFindFirstFile using VB6

  Ok, my first Smart Device project and I've come to a bit of a standstill, trying to find out what files are on the device. Tried the CeFindAllFiles, but from what I have read I don't think it will function in VB6. So, on to CeFindFirstFile and and CeFindNextFile. It all looks so easy. I'm confused as to how you set up the returning information. I keep seeing references to 'CE_FIND_DATA', but what is that all about If anyone has an example or ideas it would be appreciated.
