VS 2005 Checking If A Row Exists?
Dec 2, 2009I 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?

Checking If A File Exists And Then Saving?
May 22, 2012I haven't used System.IO before, and I'm a little stuck.I need to check if a file exists, for example C:Documents and SettingsverraineDesktopSURNAME Firstname v1.docx, if this file exists the filename has to become v2, and so on. Usually there will only be a v1, but in the case that a clients position changes we have to be able to save the new version without overwriting the old one.
How would I be able to do this efficiently? I'm uncertain to say the least. Because, if I manage to find out how to save the file as a different number, that's alright, but if that next number exists as well? I can only think of ways to do this that require a lot of code.

I want to check on the server for the existence of an image, then if it does exist, display the image wrapped in other code. E.g.
if "/images/name.jpg" exists then
<div><img src="/images/name.jpg"></div>
else
Do nothing.
Seems really simple to me but NOTHING I have tried has worked (compilation errors). I've tried examples using system.io, DIM stuff with 'FileInfo', Set fs. FileInfo examples produce 'not defined' errors, 'Set' says it's outdated and not used anymore and so on.

It feels like I'm nearly there with it but currently my listbox is displaying everything, I want it to just show the files that are missing.

Check If Directory Exists On Network?
Jun 5, 2012I 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.

Determine If Directory Exists, Create It If Not
Jan 7, 2009I 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.

Directory.exists(UNCSpec) Always Returns False?
Jun 23, 2010I 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.
Using Directory.Exists On Network Sharing UNC Path
Aug 19, 2009I'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

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 RepliesVS 2010 - Timer To Check If Directory Exists
Jun 2, 2011I 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..
