In vb.net how do you check if a ANY directory exists inside a directory I would need to know if there is a folder inside the c:windows directory (WITHOUT knowing if there is ANY directory is in there).
View 4 RepliesI have 2 tables Table A & Table B Table A has the table values that I want to be populated in a datagridview control.The challenge is that column 1 in table A contains an ID(foreign key) to a name field that is a located in table B. I need the datagrid to have the first column be a combobox that displays the names(from Table B) that are already in table A via the ID's, but reference the populating values from Table B. So that when you bring down the combobox you would be choosing from Table B data but populating table A with the ID and you would see a name there instead of an ID.[code] How do I populate my DS dataset with Table B? And how can I create a link to these two tables using a bound datagridview control?

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.

I wanted to create a login system that would have 3 tabs 1 for regular login, 1 for admin login and 1 for account creation. So far so good. It saves the accounts by saving them in a .urs file in the map called /Users/. However when this map does not exist it will show a error. I would want to know what code or so to put into the form_load which will make my program create the map /Users/ if it does not exist. As im not familiar with all the codes and stuff. The only thing i can come up with is
Mkdir "/Users/"
but then ofcourse it would create the folder users everytime i start the program. not i was still "Hello Worlding" a few days ago, so i really am unfamiliar with any sort of high-skilled programming which i probably dont understand.

I am developing a Windows Service (Yes, windows service) using VB2008 and am having trouble determining whether a remote folder exists.The IF in question goes something like this:
If NOT system.io.directory.exists(strFolder) then
System.io.directory.createdirectory(strFolder)
End if
The problem is that the above test (excluding the NOT) always returns False, regardless of whether the folder exists or not. So, even if the folder exists, the next statement tries to create an already existing folder which does not go well.
The weird part(s) - after some tests
The system.io.directory.exists() works well when I type it in the immediate window for both local and network resources
It also works well when it is within a normal app (that is, not a service) regardless of whether it is local or network resource
The exists() method when in the service works well if the folder being tested is on the local machine, but fails when it is remote network resource, regardless of whether it is a true UNC or a mapped drive.It is not user's rights, as I have tested with both my own user and the localsystem user and have tested with network resources where I do have access rights.When I try to debug, the PC starts playing the Twilight Zone Theme (Ok, I am kidding about this one )Doing some searching I found that others are complaining about the same behavior, but no suitable answer has been found.
I'm building an application which require to use Directory.Exists on a network share UNC path. I know how to use that function, and how to implement it in my code, it's working perfecty locally.
Here my setup:
- VS2003
- .NET 1.1
- It's an Outlook Add-In
Here the code :
Dim realpath as string = "\myserverfolder$subfolder"
Impersonation.ImpersonateUser("admin", "DOMAIN", "adminpass")
Dim isDirExist As Boolean = Directory.Exists(realpath)
If isDirExist = False Then
Directory.CreateDirectory(realpath)
End If
Impersonation.undoImpersonation()
If I build this code, and register it in Outlook with my personnal account (admin), it's working fine, I receive true. If I build this same code, an register it in the Outlook of a normal employee (user only), it's always returning FALSE, no matter if the directory exist or not. The share is set to everyone allow, and I tried giving everyone access to the ACL, and it's the same result.

View 5 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:

I 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.

I think this is a really simple question to answer but I can't find a better solution. Basically I am importing data from an external source and as I go through importing each for I am doing a for loop to see if the row already exists; this is taking a life time and I feel it is a very simple way of doing it. Is there a better way to see if a row already exists using specific columns and key indexes?
