• .Net: How do I check for illegal characters in a path?

  - by Mike Pateras

  Is there a way to check if a String meant for a path has invalid characters, in .Net? I know I could iterate over each character in Path.InvalidPathChars to see if my String contained one, but I'd prefer a simple, perhaps more formal, solution. Is there one?

• If you stick to standard coding in .NET, is there reason to manually invoke the GC or run finalizers

  - by Matt

  If you stick to managed code and standard coding (nothing that does unconventional things withe CLR) in .NET, is there any reason to manually invoke the GC or request to run finalizers on unreferenced objects? The reason I ask is thaty I have an app that grows huge in Working Memory set. I'm wondering if calling System.GC.Collect(); and System.GC.RunFinalizers(); would help, and if it would force anything that wouldn't be done by the CLR normally anyways.

• How do I diagnose a failure in the Membership service on an ASP.NET remote site?

  - by ProfK

  Yesterday I added a custom MembershipProvider to an ASP.NET web application, but when I deployed the application to its remote host server, it failed. I know I had the login info correct, and I also know that for nearly any exception in the login process, the Login control displays the standard error message, "Your login failed", so I assume something is wrong in the code/config. What can I do to diagnose what is wrong on the server?

• ASP.Net - How do I allow users to enter html tags in textbox without runtime errors?

  - by Coder

  I have an input textbox on an asp.net page and when a user inputs any tags like break tags or bold an error occurs. I currently am using the following to encode the input: Server.HtmlEncode(mytextbox.Text) However this only encodes characters when they aren't phrased as an html tag, like if the input is "<<<" is there a way for me to allow the user to put the tags in without it leading to a runtime error? Thanks.

• How to modify raw HTML of ASP.NET page on PreRender?

  - by ace

  I want to access the raw HTML code that my ASP.NET System.Web.UI.Page is about to render. How can i do that? Is there a property or method like System.Web.UI.Page.HTML or something like that.
