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.

How do I check if a directory exists?
View 1 RepliesI have a security timer to check if the directory exists which I want to access after it's been created by an external application, but what I have done doesn't seem to be the solution although it sounds like a very normal solution to me.
What I have done:
1) External application gets run which is going to create the directory
2) I set the variables to make the timer able to know what to check
3) My application needs to wait till the boolean variable gets set to true, so I put it in a
While:
vb.net
'Non existing files protection
While (Not bDirectoryExists)
If bDirectoryExists Then
Exit While 'In case it got created in the meanwhile
End If
If Not tmrFileCheck.Enabled Then
tmrFileCheck.Enabled = True
End If
End While
4) In my logic, the application should go out of the while now because the variable is set to true, and the code moves on, which never happens..
I'm having trouble finding a reliable method to check if a directory (folder) exists on an FTP server. I want to create new directories and then upload files into them but thought it best to check if the directory already exists. Although attmepting to create a directory that already exists does not seem to cause any errors, it does waste a bit of time.
This code reliably checks if a FILE exists:

Have only just started trying Visual Basic after using Delphi almost ever since it first came out. How on earth do I see if a file exists? - simple terms please
View 2 RepliesI have a process serves as an application updater.It checks it's local cache of files and compares this against list of files online.On it's first run there are no files in the local cache and it therefore downloads ~100 of these files.[code]This appears to work very well, since Explorer confirms that all files are extracted and available.However when I later run this process again, it cannot verify the existence of 6 of these files and therefore tries to download them despite the fact that they are clearly both present and up to date.The offending code is a simple File.Exists call which appears to deny the local existence of these files, and therefore tries to get them again.The system continues to work well, but over time the continual downloading of these 6 files is going to get kind of silly.

How do I check if an HTML element exists? This element will only "show" on a certain event. ex: numbers in a non-number textbox or something. I tried
If WebBrowser1.Document.GetElementsByName("ElementName")

see if an object is already in a generic List(Of T) than the way I am currently doing it? The way I do it at the moment is like so:I have a method that I call each time I want to check to see if an object exists in the list (if it already exists I do not want to add it again) and the list to check is passed in to this method along with the item that should be added to it:
[Code]...
So as you can see this function just loops through the list that was passed in and if the DisplayName property of one of the items in the list is the same as the ProgramName argument that was passed in to the method as well then it returns True to indicate that this program is already in the list.I thought about using a Predicate with the List.Find method but cant see how I would get it to work because that predicate method will not have any way of referencing the list (its a method local list, not class level)
