• Visual Basic while inputbox

  Hi, i'm using vb 2005. my question is: i have this code: Dim x As String = "" While IsNumeric(x) = False x = InputBox( "Enter a number" , "New Value" , "0" ) End While How can i exit a while statement if the user pressed the cancel button in the inputbox Thanks... when I tried, if you press the cancel button then it returns the string length of 0, so in your while loop you could have something which checks the string length to see if its 0 and if so then exit the while loop. This does work however if the user presses ok and there is no text, it would exit the loop:   while IsNumeric(x) = false and x.Length > 0  & ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Boot Camp + XNA

  Anybody tried to run XNA on Bootcamped Mac I tried my schism game out on a bunch of computers it works just fine. However, when I tried it on a Bootcamped Windows XP Mac...The screen rotated 90 degrees...Everything worked right, controlls and such but I could only see half of my screen. A bug with the graphics device, or maybe drivers on the Mac Anybody got any ideas I've been running code on a bootcamp Macbook and it's been working fine. There is a key sequence that the Mac has to rotate the screen, so that may have mistakenly been hit. I've run both the Spacewar demo and my own code without issues. Hardware acceleration seems to work fine as well. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. FrameTransformMatrix in .x-file meshes is ignored

  Hello. I use XNA (beta2) and try to load a .x-file into the content pipeline . First everything seems to work fine, but I wondered about the aspect ratio of the shown objects. If I load the .x-file with the "DirectX Viewer" from the DirectX SDK the 3d objects are shown right. But when I load them with XNA the entries in " FrameTransformMatrix " seems to not being calculated. I use blender and its exporter to generate .x-files. Does anybody else noticed this problem Bestregards, MircoS Hi. @leclerc9: Thanks for that link. I guess I will take a look at your custom importer later. (btw.: nice and clean site) I took a closer look at the loaded model and its meshes. The correct TransformMat ...Show All

• Windows Forms app.application Publish file

  Hi, I know this has already been posted, but I need to get it clear in a simple way. The 'app'.application file is created when you publish an application to a web/ftp server, along with other files. The publish.htm page shows a button linking to the 'app'.application file and I can correctly install it, but a friend of mine (and maybe many more people too) get the 'app'.application file contents displayed in his browser. He has the .NET Framework 2.0 installed (installed automatically with VB 2005 Express), and I would like a simple solution to resolve this issue, without reinstalling .NET 2.0 (unless you are sure it resolves it). I also heard that it has to do with MIME types , but I'm not too familiar with this term to unders ...Show All

• Visual Basic Are there any escape charecters in Visual Basic?

  I know there are in almost every other language, but are there things like \n, \r, \",.... Other than the constants that Spotty mentioned, there is one way of escaping quotes - basically, within a string, any pair of quotes is considered as a quote character to be included in the string. So: dim s as string = """" will result in a string with one character: " dim s as string = ""Murder!" she said." will result in the following text when printed: "Murder!" she said. ...Show All

• .NET Development -Using Sproc to insert rows in the DB and the Sproc returns identity columns to my dataset

  If we use sqdataadapter to insert data from a datatable into a table in the database using an SPROC. The Sproc also returns the identity column values that are created by the database. If those identity columns are called “IDcolumn” in the physical DB but in my dataset I call them “MyIdentity”. So IDcolumn is an output of my SProc I use : Pm.Direction= ParameterDirection.Output Then I use pm.SourceColumn property : Should I use IDcolumn” or “MyIdentity” Like this: Pm.sourcecolumn=”IDcolumn” or like this: Pm.sourcecolumn=” MyIdentity” Thank you Thanks! I think i didnt quite understand the question, but yes of course, it would map to the datatable/dataset column name/source   ...Show All

• Windows Forms Adding a bat file to an installer

  Hi, I am looking into adding a small .bat file to the deployment project, to add a switch to a .exe that I would like to run during the install. If I add a bat file how to I make the installer call it I am think just the process of Add a File will not actually cause the file to run.
