• .NET Development Database secure login to program

  Hi, I am creating a VB.Net program and know basic VB programming. The program will at first ask you to login. I want an admin who can change his password and also add users. I am not sure how to do this. I know how to access SQL databases but not how to make the program check the database each time a user inputs a login and them direct him to his account or how he can change his password without being able to access that of others. If anyone could give me a word of advice thats easy to understand I would be very grateful. Well again there are many ways of doing this. you could fill a dataset with the data of the correct user, then check to see if there is a record in the dataset, if there is then we kn ...Show All

• Visual C# @ operator, what is its meaning

  Hi! In example, in this code: fs = new FileStream (@sFile, Modo); What's the meaning of '@' I'm looking for, but i don't know what's the name in english of this character (in spanish 'arroba'). Regards. The "@" character has another use that may be more in line with the example in the original post. By prefixing "@" to a keyword, you can use that keyword as an identifier. For example, you can do this: class @ void { ... } This defines a class with the name "void", even though "void" is a keyword. You can then refer to it in the same way: @ void foo = new @ void (); Obviously, this is a rather contrived example and you should avoid wr ...Show All

• Visual Studio 2008 (Pre-release) Enabling HTTP Compression

  What's the easiest way to get gzip compression for a WCF service using ws or basic Http bindings We're hosting in IIS, so can we just turn on IIS's HTTP compression for .svc files (we already require AspNetCompatabilityMode) I saw the custom encoder example, but that looks like a total pain, relatively speaking. But if it's the only possible way... Thanks, Michael I am not quite sure what a custom encoder is but to add compression to my web services all i did was create a partial class for the autogenerated Service proxy class as shown below: Option Strict Off Option Explicit On Imports System Imports System.ComponentModel Imports System.Data Imports System.Diagnos ...Show All

• Visual Studio 2008 (Pre-release) Asynchronous LINQ???

  Given WCF's decent support for asynchronous server-side methods (going by the docs), is it likely that LINQ to SQL will support asynchronous query execution in the future Perhaps a BeginToSequence method, eg: IQueryable<Customer> customers = dataContext.Customers.Where (c => c.Name == "Jones"); IAsyncResult result = customers.BeginToSequence (Callback, null); It might be worth including such methods because for the end-programmer to add them could involve re-writing DLINQ. An alternative would be modifying the thread pool so as to be tolerant of blocked threads, thus allowing blocking methods to be used (at least in medium-load application servers) without problems. Obviously the thread count would rise, but this might b ...Show All

• Visual Studio 2008 (Pre-release) Security Validation with Operation Attributes

  Say I want to place attributes on the interface for a services operation or on the concrete implementation of the services operation. [OperationContract()] [MyAttribute("This is the sample attribute on an operation")] void MyOperation(); Now, during the authorization process, I want to be able to get the attribute off that operation for the current operation. I can't find the OperationDescription nor can I find how to get the type that will be instantiated and the method it would call so I can find the attributes that are applied to that method. Should I be using an IOperationBehavior instead and where should I put the info I'll need to extract so that the ServiceAuthorizationManager can get access to it to do a retrieva ...Show All

• Visual Studio Conditional Branching of Recipe Actions

  OK guys, This is a bit long but a good use case I think. I'm trying to get control over which recipes get executed based on user input. I would rather not approach the problem by stashing the conditional logic in a custom Action as 1. I have no source for the Actions (using TextTemplateAction here). Containment of this Action from my own is problematic at best (was told I needed to spawn another TemplateHost instance just to pass the Dictionary values to the contained instance. PITA & heavy) 2. Subclassing from TextTemplateAction and throwing the logic in the subclass is a bad approach considering that these Actions are reusable across recipes, some of which may not be configured to work with the same Dictionary values of ...Show All

  Is there any way to use image slicing in WPF I have a PNG image that I want to use a a button background, but I need to slice it to get the scaling correct. I see the WmpBitmapEncoder has the slices properties, but I am not sure how to use it. Thanks, Joe Breaking up the image into 9 pieces, like a tic-tac-toe board. The 4 corners wouldn't be resized. The top and bottom would only be stretched vertically, left and right stretched horizontally, and the center be stretched to fill. Basically, the image would be resized, but keep the origional border size intact. ...Show All
