  Is there a way to allow Visual Studio to automatically overwrite code files without asking me (the user) each time if the file is read only There is no easy way to accomplish this. You could however write an extension for Visual Studio that does this but personally I would not recommend that as source code controlled files also depend in the Read Only attribute and you do not want to mess with this. ...Show All

• Pockey I need to acces flash memory device

  Got an mp3 player (samsung yp z5 to be precise)I bought some time ago.Problem is its not connecting to my PC because I suspect there are some files inside it that have been erased.Is there anyway or some class I can use to view the remaining folders inside by force and maybe I can replace them.Could it be something to do with the Media Transfer Protocol.Being a novice I don't know where to start it will be a problem with the devices, or drivers, itself. If Windows can't seem to find them/remove them then there really wouldnt be a way of doing it in C# especially if they are hidden since it would make a call to Windows asking to get the hidden files and if Windows can't see them then I dont think C# would, ...Show All

The question is: If I create an abstract worker class as such: public abstract class MyClass { public abstract void MyMethod( DataEntityAbstract Entity); } Then try the following in its derived class: public class ThisClass : MyClass { // ThieDataEntity is derived from DataEntityAbstract class public override void MyMethod( ThisDataEntity Entity) { // Do Something } } Visual Studio 2005 will throw a compilation error.

• Carsten Kanstrup Not finding a web proxy class that should be auto-generated

  I'm having difficulty running my web app. It was working correctly, but I had to move the project files around. After moving them, I added the web site and service back into the project. My service works perfectly but my site can't seem to find the class UserService.UserService (which I believe is auto generated by my web reference). I tried removing the web reference, closing VS, opening and cleaning the solution, closing, then adding it back in and deploying - but no luck. The disco, discomap, and wsdl files are added to the project correctly. Here is the exact error message C:\philipd\Visual Studio 2005\Projects\...\Global.asax(5,5): error CS0246: The type or namespace name 'UserService' could not be found (are you missing a using direc ...Show All

• Antioch some questions I could use a little help with

  Hi all, I am trying to understand what these methods are IsOdd, IsInteger, and extractAlpha. Also, how would you implement them in the following statements. bool IsOdd(int number) bool IsInteger(string strValue) and string ExtractAlpha(string strValue) Thanks James, thanks for the reply. I was not asking for homework help, my main intention was to find out if these methods were in the c# language in the .net platform. My fault for not clarifing my post. Anyways, I got a c# programming e-book for example test and it didn't specify if it was for the .net platform and it said to implement those methods.
