If my class has NO destructor, an it goes out of scope. GC runs at certain time, now will it simply reclaim memory from my class OR will it call its destructor or Finalize () on it? And does the .net framework class like SQLConnection implement a destructor? I saw it has a Dispose () implementation but didn't see the destructor using "Go to definition".

I have a WindowsForm that has a DataGridView that shows output of my app. The class with the button is DriveRecursion_Results.cs. I want it so that once the button is pushed by the user, my method FileCleanUp() in my SanitizeFileNames class is called. I'm not quite sure how to do this though.Here is the code for both classes:

I am beginner in web applications development. I started one little project and host it on source forge "https://homoco.svn.sourceforge.net/svnroot/homoco". And I started implementing authentication in this application to learn how it works. From my experience people never use out of the box things so I want to implement this stuff alone (like in real world projects). So some questions:
1) Is there any reason to use membership out of the box? To use database table schema, stored procedures etc. that tool generate for developer. I think that this lower control over code and I decided to implement it my self. I don't know if I am right.
2) Is my approach in this demo project good or bad (if someone have time I like to do just a little code review)? I created database based on business rules. Not using database schema that membership provider require. Extend "MembershipProvider" class to satisfy my needs. Implement queries to database myself.
3) Now, this question is a little wired but I have to ask it. If we make custom Membership Provider and do sql queries alone, implement all MembershipProvider class methods ourselves, and in application use Membership.blabla() why is this approach different from not extending MembershipProvider class and putting all this methods in some unique class and call its methods then? I hope that someone understand what I ask here.
I am sorry for three questions, but I really trying to find the best way to implement this feature in my demo project like it is a real world application.
So I have Test1.aspx, Test1.aspx.vb. The LocalResource files, in the App_LocalResources folder, Test1.aspx.resx and Test1.aspx.es.resx. I also have a class called TestTheData.vb in the App_Code folder.

View 2 RepliesI'm building a menu controller class and I have a database with the Controller/Action strings in it. I want to dynamically build a menu reading from the database and generating the URLs to use in the menu's <a href=''> HTML that the class renders. I can't use Html.Action() in my class. I've tried adding System. Web.Mvc, but this doesn't help. Is there a way to generate a page's URL when given the Controller and Action? Maybe referencing the MVC equivalant of HttpContext.Current like I used to do in WebForms?

View 2 RepliesI got a ASP.Net website (webforms application in C# - .Net framework 2.0) with Master Page, webforms and a GlobalFunctions class in App_Data folder where i do have ErrorLog functions and few other generic functions. Everytime an exception is caught in my webform it calls this GlobalFunctions.Errorlog function to log the error in my database table. After the exception details are written to the database table, I also would like to redirect the user to my ErrorPage.aspx like
Response.Redirect("ErrorPage.aspx",false);
However since i am inside a class (GlobalFunctions.vb) and not a webform, I don't know how to redirect this to ErrorPage.aspx since i can't access Response class.
