I was looking for some stuff online, and i was looking through my reference sheets for vb.net, but it seems in the code i have found, there is declare in methods. Below is an example i am talking about. The thing is, that i dont recognize it and believe that it is an earlier version of Visual Basic ( 6 or earlier) which used it. Should i just keep looking for different code?
Public Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal _
lpSubKey As String, phkResult As Long) As Long
Goal: Find information on how to implement a method which will check if a certain DSN exists, and then if it does, extract the information and use the information for connection purposes.

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. It takes more then 2 minutes to check for all as it is trying to get response of all of them. 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
how do check if a referrer exists?

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?

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.

I have a database created and tables inserted into it. One of the tables is called UserLogin. It consists of two columns, BarcodeId and Technician.

I can't seem to work this out... I've got a program that references a network path. The problem is that the network files are not found when I run the program from various computers. If I have the user navigate to the network path directoy and then run the program it works perfectly.
The problem is that whenever the machine is restarted I run into the same problem and have to manually navigate to that path before the program will be able to find the files.
I then tried several checks to see if the directory exists but it's not working.
Public Sub FillListBox()
If My.Computer.FileSystem.DirectoryExists("\AB eamportalShared%20DocumentsJustin%27s%20AppsFeedback") Then
