• .NET Development Using Internet From C#

  Is it possible to use some .NET library to download a file from the internet automatically to a specified directory Let's say I have an excel chart on my website, and I want to download it to C:// Also, I want to be able to do the same with a web page, i.e., I want to go to www.mywebpage.com/index.html and download index.html to a certain folder by using .NET. Will this take a lot of complicated code Can I just use a .NET library, or must I use Win32 API or something like that No I'm using the System.Net.WebClient Class.. All the event handlers etc. are in there, but I dunno how to even get the bytes and all that..if i did, it would be somewhat easy to get the percentage and update a progress bar.. ...Show All

• Visual Studio 2008 (Pre-release) WCF and N-Tier Web applications

  Hello, I would like to know how would WCF add value in a typical n-tier web application, where the presentation layer talks to the business logic layer in-proc for performance purposes. i.e. there's no physical seperation between all layers and hence the UI layer has access to the db server. Please note that web services are not always necessary as an additional layer as the main purpose of web services is to expose the application functionality to other consuming applications, and so decisions to make the contract coarse-grained is not valid since no network overhead is incurred. Please advice. Thank you, But the application design should be flexible enough to allow for either running locally ...Show All

• Windows Forms How can I set Form's position to most behind?

  I want to do this: When I leave Form1, it should go to behind of other all forms. How can I do this Thanks and regards... When the form is deactivated call SendToBack to send it to the bottom of the Z-order. Determining when the form is deactivated is a separate story. You could do that when the form loses focus or when it is truly deactivated. Michael Taylor - 2/1/07 http://p3net.mvps.org ...Show All

  In my TFSBuild.proj file, I have a customized sequence of targets that the AfterEndToEndIteration target depends on. This sequence removes two folders to clear old data, then recreates them so that my build can drop certain release files into them.

• Visual C# Typing in Visual Studio 2005 Text Editor is extremely slow

  Has anyone else noticed that typing in Visual Studio 2005 is extremely slow   Whey I type it seems that the screen is always 2 words behind where my hands are.  It makes it extremely frustrating to get anything done. I'm mainly referring to C# code.  It seems like Intellisense is going nuts trying to guess every word I'm going to type and never actually prints the characters to the screen. Has anyone else experienced this   Is there an option I can turn off to get my text editor back ! By the way, I have a very fast computer with Dual 3.0 GHz Zeons with 3GB memory and everything else that should make "typing" very fast.     Sub ToggleCSharpNavigationBar()        ...Show All

• Visual C# Differences between delegate invoke and call a method directly??

  Hi! I'm studing about delegates and how works before studing asynchronous callbacks, i understand differences between call a method directly and call a method by delegate asynchronously with BeginInvoke, it launchs a background thread aganist the pointed method, but i don't understand which's the difference between call a method directly and call a method by delegate with Invoke ... i think that both are the same way to call the same method ... probably because i don't understand well the difference :P Can somebody light up me Thanks in advance. Regards. Ultimately they are identical. The difference is in performance and benefits. If you directly call a method then the compiler will generate the necessary code to look up ...Show All
