• Visual J# while causes Program to Stop

  static String ExtractFilePath(String Path) { String VirtualString = String.Copy(Path); int i = 0; while (VirtualString.IndexOf("\\") > 0) { i = i + VirtualString.IndexOf("\\"); VirtualString.Remove(1, VirtualString.IndexOf("\\")); } return Path.substring(1, i); } This code cause my program to "suspend".

Addtionally, it contains the other logical error. Execute the following code to know String.Remove(int) and refer String.LastIndexOf() method. public static void main(Stri ...Show All

• Visual Studio 2008 (Pre-release) how to get the datacontext of a dropdown in a gridview

  Hi, Just wanting to know how to get the "collection" that is used to populate "a combo box";(datacontext or itemssource); that is used in a grid view. I want the syntax in code . Thanks. comboBox.Items gives you access to many useful properties of that collection: comboBox.Items.Count comboBox.Items[3] More precisely, these properties are evaluated with respect to the collection view in effect; so if you've sorted and/or filtered the view, the count and the indexer will take the sorting and filtering into account. If the collection was set using ItemsSource, then comboBox.ItemsSource gives you the actual collection. You'll have to cast the result to the collection type you expect. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Binding resources to XNA executables?

  Hey Everyone, Is there a way to bind a resource to an XNA .exe, i.e. a bitmap, so the resource in question is "folded-into" the executable Any advice/help would be most appreciated. Thanks! Does the old way of using an "embedded" resource still work Thats how I did it: Create a content inside my solution (i.e /Textures/Image.dds) In the Box.X properties I select: Build Action: Embedded Resource In my code I do this: //meshMaterials .Specular = MatList .Material.Specular; s = assem.GetManifestResourceStream(AssName + ".Textures.Image .dds" ); meshTextures = new Texture (device, s); if that still works, I can use my old concept of ...Show All

• Windows Forms Form Security

  Whats the best way so I can make privilages/form to user in my application meaning: disable buttons for specific users, hide menu Items, disabling context menus Whts the best way to do this I want to be far a way from if conditions, so if I can set privalages from one place any Ideas Thank you well you would need if conditions otherwise there wouldnt be a way of doing so. I guess you check the login type of user, if they are of a certain group/member/user then disable the items you want, else, enable them all. That's all you need really just a single if statement perhaps, to check the type of user and if they are not of the user you are wanting to give full permissions, then disa ...Show All

• Visual Studio Express Editions Should I learn to program?

  I am interested in programming, but I am a beginner. Basically I am curious as to the advantages of being able to program for someone who may not want to do it for a living. Warning! The Other Side of Programming... Okay - so here's a few thoughts for you to consider from an ol' programmer (started back in the grand ol' year of 1980 Programming won't let you 'keep' it as a mere acquainance. It will demand more and more of your life if you like it. If you don't you'll never have a break-through moment when all the bits come together.

• .NET Development Reading SerialPort (with .Net 2.0)

  Hello, My robot sends me serial messages (packages) starting with a STX (0x02) character and ending with and EOT (0x04) character. Messages may have variable lenghts and within messages (except from first/last character) no other STX (0x02) or EOT (0x04) characters exists. My robot can send multiple messages at any time.

But how can I make SerialPort execute an event if an EOT (0x04) character is received All tips are welcome. Henk The SerialPort ...Show All

• Windows Forms Placing Shortcut That Can Be Accessed by All Users

  Hi ! I have created a Setup and Deployment project to install my application. I have a help file that I deploy into the Application folder which is under 'Program Files' folder and I place a shortcut to it in the User's Program Menu under a folder. The installation is done by the Administrator and the application is installed for 'ALL USERS'. Everything else is fine but when some other user logs on to the system and tries to access the help file from the User's Menu by accessing the shortcut, the help file does not open. Instead the application begins to reinstall somehow from the original location. I would like the help file to be accessible to all users. I know there is an option to use 'Custom Folder' during setup in the 'File Sys ...Show All
