Game Technologies: DirectX, XNA, XACT, etc. Copying between textures
Hi, I am currently working on a tile map engine and need the ability to build a texture (map) from my tile set which is a texture with all my tiles contained within it. I have been able to create a new texture but cannot see how I can copy sections of my tile set into this texture. If someone could give me some pointers, it would be much appreciated. TIA, Andy Andy, Glad you got this thing going... it seems the forum is full of helpful people recently. Hope you don't mind me using this as reference... it'll be interesting to do some tests with this. ...Show All
Game Technologies: DirectX, XNA, XACT, etc. A way to generate beep through sound card
I would like to generate a beep sound (for example a sine wave sound) with a particular frequency (Hz) and length (ms). How can this be accomplished with VB.net Rather than using pc speaker, I would like to use DirectSound or so... Thanks, but I can't find an example on TheZBuffer.com. I searched and searched... I found this piece of code: http://www.codeproject.com/csharp/messagebeep.asp It seems to do the job, but how to extract only the generate beep part and convert it to Vb.net I'm just a newbie programmer, so if anyone can do this, I would be most grateful! So I need just the function to play a beep with frequency X and length of Y milliseconds. ...Show All

Visual C# How to disable drag-and-drop in Soluction Explorer?
For many times I accidentally dragged some files from one project into another project in my solution. Is there a way to disable this This is quite annoying. Thanks! Well, there should be. The problem is not just to be careful. Sometime when you expand/collapse treeviews in the Solution Explorer, the action is miss-intepreted as drag-and-drop. And because the treeview is changing, it's hard to see what files were dragged/copied. .Net is all about productivity, but I can tell you this isn't. Why I'm hanging on this issue Because it just happened to me - again. There's no joking on this issue, this is a real problem. ...Show All
Visual Studio 2008 (Pre-release) Interprocess communication on same machine
Hi, I need to implement interprocess communication between two .net 3 processes. The communication is one way (one process feeding information into another). The processes will most likely be running on the same machine. Messages will be rather infrequent (no more than 7 per day), and rather short in nature (500 bytes or so), but they need to be processed quickly when they do occur. I don't want to run IIS or any big server stuff on the machine. What is the best approach Is WCF connection points overkill .net remoting Thanks! Wow. Thanks for the suggestion. This is pretty cool technology. I read about it and it sounded like overkill, but I got a chance to play with a few samples this week-end, and I like it a lot. Th ...Show All
.NET Development How to get the error message from Login Provider Validate() method?
Hi, I am trying to use Login control (framework 2.0) with a custom provider for authenticating user. As the custom provider inherits abstract class MembershipProvider, it implements method ValidateUser(). The method just returns a bool and if there is any exception it goes as page error; an unhandled exception. I would like to handle this exception in Login control, but do not find any way or place where I would get this exception. Could you please tell me how do I handle this exception and have a custom message to be displayed to end user instead Thanks in advance, Maithili. Hi Rodrigo, Thanks for your time. I tried that one but in the LoginError event i didn't ...Show All
Visual Basic Thread Problems – Strange Loop behavior
I have a loop inside a threaded sub and inside this loop is a simple check that one Boolean is true and another is false, if so it will append some text to a string builder. This loop is an incoming E-Mail from a socket (hence the thread) which was connected and then threaded. Now the loop works fine apart from where it appends to the string builder (i have tried a normal string also but it the same). Now this loop accepts packets from port 25 and sends them onto our Exchange server. Collects what exchange sends back and forwards them on to the SMTP client forming a SMTP filter. I no for a fact the loop is working because the E-Mails arrive perfectly that pass through the filter. This is the code that does not run every time the ...Show All

.NET Development Windows Services and COM interop
Here is what I am trying to do: I have a very simple test DLL that has one operation called 'Get_Stuff(String)' this simply returns a string with some hard coded text. This works fine if I create a windows app in VB and then call the operation on the DLL, so I know the code is right. However, if I create a Windows service (again in VB) and use the same code I get an error. I've set the service to run under my login rather than local system because the DLL needs to access network drives. The error I get is: Error: 429, Cannot create ActiveX component. As I say, identical code works fine as a normal windows app so does anyone know what is going on here As I understand it the service will still be running in a dif ...Show All

SQL Server Create Destination Table Dynamically in a program
HI, I'm programmatically able to import data between tables when the Destination table already exists but when Detination table has to be created on the fly (Name will be provided), I'm not successful in doing so.

Visual Studio Express Editions Using Lession 9 sample. Record is not saved in database.
I am learning VB 2005 Express Edition. I am using a sample in the lession 9 of the VB 2005 Express Edition. The sample comes with 3 records in the customer table.
