I am using Caspol.exe to install a custom Permission set and add Code Groups for my .Net 2.0 Windows Application.
I have created a Console Application that uses caspol.exe to add Permission Set and Code Groups. I first install the Permission Set and if I do not get an error, I continue to install the Code Groups
Now sometimes I need to add a new Code Group to the client machine, so I make the changes to the console app and it is executed on the client machine. If the client machine already has the Permission Set installed, it returns an error and stops the further processing.
So, I want to know if I can check whether a custom Permission Set is already added or not?

This is the standard way of checking if URL exists [code]....
return true; } catch (Exception ex) { return false; } But my problem is that we have to check it for around 100 URL's.

Is there any way that we can check if URL exists without getting complete Response so that total response time is less.
In my code, I want to check if a referrer url exists and if the referrer url contains a specific sub string. I know how to check for the sub string:
If( InStr( Request.UrlReferrer.ToString(), "some sub string here" ) > 0 ) Then
But I don't know how to check if a referrer exists or not. No refer exists if the url is entered in manually in the address bar. So I tried this, but this does not work:
If (Not (Request.UrlReferrer.ToString() = "")) And (InStr(Request.UrlReferrer.ToString(), "some sub string here") > 0) Then

I have a small database. 2 main tables called CaseDetails and Checks.Each record in CaseDetails can have 3 checks recorded against it in the Checks table. But can only have one check of each type (check types 1, 2, 3).I have 3 linkbuttons which will take the user to the input form for each 'check'. If a 'check' already exists i want to hide the linkbutton that takes the user to that 'check type' input form (the 3 input forms have different fields).So what i need to do, is connect to the SQL database and see if a record exists for each 'check type' and hide the linkbutton to prevent users from entering another record with the same 'check type'?I have tried reading the reults into an array and examining that array, but havent been able to do so.

I am trying to figure out how to check if a registry key exists. If it does, do nothing, if it doesn't, recreate it.I've found numerous resources on the subject, and have made progress, but one little thing is stoping me.[code]The problem is that this reports "Not Found", even though the key 'regkey' exists in the registry. Also, if I remove 'regkey' from the code, it reports "Found". So it does find the subdirectory in the registry.My question is, how do I check to see if the 'regkey' exists? I'm running Windows XP Pro SP2.
