• Visual C# Validating a Form opened with ShowDialog()

  Hi, I’m using a Form in the Dialog mode “frmIP.ShowDialog()” & I’m trying to validate the input so as not to be able to click OK button unless there is a string in one of the text boxes. (it would reset the focus back to the text box & cancel the click event) I have using the Validating event of the textbox I want to validate. Although this works when I move focus to another text box, the buttons do not trigger the Validating event when I move to them. The buttons & Form are both set to ‘Causes Validation = true’; As a test, I tried a Message box but this simply gets called then the dialog box closes. How can I validate a textbox which is on a form opened with the ShowDialog() method. Any ideas would be ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. ClientBounds Problem

  I'm having problems with deploys to my 360. More specifically, the resolutions that the games are displayed in. I can deploy programs fine, but when I run them, my ClientBounds don't seem to match up with the DisplayMode.Width and Height. It basically means that the resolution I'm expecting to run in runs out at about 3/4 of the screen width and height. I'm sure it's something silly I've overlooked, but I can't seem to find the problem.

• SQL Server Multivalue Parameter SQL Server 2005 SP1

  Hello, I've installed SP1 for SQl Server 2005 and I noticed that the option "Select all" on a multi value parameter drop down (using web browser) is missing. Even if I can see it on VS 2005..... Anyone can help me Thank you very much. Hello, I faced the problem that on my development server <select all> was displaying and on the production it was not due to SP2 on development compared to SP1 on production. SP2 was then loaded on the production server and rebooted the machine even then the <select all> cannot be seen. Would i need to reload the report or any futher fixes. I know I am close to reaching a solution Thanks ...Show All

• Visual C++ Patching EXE files.

  Hello, I am trying to patch some string in an executable file. Patching normal bytes goes without any problem. But when I try to change the ascii chars, the file gets corrupted and the size increases to ~700mb. First I used the fseek to go to the offsets. 'offsets' is a long int array containing the offset addresses. fseek(stream, 0, 0); fseek(stream, offsets[r], SEEK_SET); //in a loop | stream is a FILE* for opening the file in r+b mode. Then I tried patching the byte with the right ones in 'patch', 'patch' is an array of chars. fwrite(&patch[r-1], sizeof(patch[r-1]), 1, stream); This works fine for changing normal bytes, but for some reason it gets messy when I try it on an ascii string. Any opinions of where the problem might be re ...Show All

• Visual Studio Team System TF53010 / TF14055 errors

  We have a TF53010/TF14055 issue which may be similar to ones reported by others: In a nutshell, we have a 2 tier TFS installation on Domain A. The user accounts used by the TFS installation are on domain B. Additionally we have a 3rd domain (call it C) that is a legacy NT domain. The user accounts in question on domain B were migrated from domain C several years ago. Our problem only occurs when the last DC (the PDC) in domain C is shut down. When we do this, email notifications from the TFS application tier on domain A to users in domain B stop working with the error 6008 (The identity DomainB\UserXXX is not a recognized domain identity). If we switch the DC from domain C back on the problem goes away. What I don't understand is why hav ...Show All

• .NET Development How to push data from Web Service to Client side

  We have three-tires application and would like push data from web service side to client windows application side. Any idea about that Thanks for any help Web Services are better used for pulling, not pushing data. Since they are built on HTTP, they are stateless like a webpage and do not maintain a connection to the client. In order to push data the client would need to have a service listening for pushed data. You might want to look at another technology like .Net Remoting, WCF, or TCP/IP. ...Show All
