Determine If Directory Exists, Create It If Not

Jan 7, 2009

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 have a function in VS2008 VB.NET that creates a dataset and reads field values from that were loaded from a SQL Server 2008 database tables. The tables are from varied sources and in some cases particular column/field names are different. Some use a long name; others use a short name. I need to determine whether a short name or a long name is being used.Pseudo code:If row("ShortName") Exists then ReadDataFrom r("ShortName").ToStringElse ReadDataFrom r("LongName").ToStringEnd If

Determine If URL Exists Without Requesting The File?

Jan 25, 2010

I would like to check if a URL exists -- without requesting the file. The program needs to check if a PDF or Excel spreadsheet exists at a particular URL. If it does, it might want to download the file, but it should not download it every time.

I currently use the WebBrowser.Navigate method to do this, but it always downloads the file. But I don't want to actually download the .pdf or .xls file, I just want to determine if the URL exists.

Link To XML - Determine If An Element Exists In A List?

Apr 27, 2012

I am working with LINQ to XML in VB (although answers in C# are great, too). First off- my code works, so this is not critical. However, I can't help but think that what I'm doing with conditional logic should already be doable using the LINQ query itself. Here's what I've got:

'Get the Description elements in the ResultData section where the value is "Op Code"
Dim opCodes As List(Of XElement) = (From c In xdoc.Descendants("ResultData").Descendants("Description")
Where c.Value = "Op Code"[code].....

Please don't be too critical of my method of locating the sibling nodes- the XML files are produced by a third-party testing device and this is the only generic way to get the values I need. What I'm really looking for here is a better way to handle the If block.

Forms :: Determine A Dynamic Drive Letter For A Directory On The Removable Drive And Then Open That Directory In An Explorer Window

Feb 19, 2009

First off a short background of the project I am working on- I am developing a program that will be run off removable media (i.e. USB Flash drive). This will be a �virtual desktop� which you will be able to take with you and have the same �desktop� on any system. As we know drive letters can change with each host system the drive is plugged into, I need to be able to determine the path for the flash drive and access a specific folder ( i.e. My Documents)

I have an picture box(representing the icon) placed on my form (form1) and when I click the icon I want to be able to open and view the a specific folder from the portable drive. I need a click event that will determine a dynamic drive letter for a directory on the removable drive and then open that directory in an explorer window.

Check If Directory Exists On Network?

Jun 5, 2012

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

Directory.exists(UNCSpec) Always Returns False?

Jun 23, 2010

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.

Using Directory.Exists On Network Sharing UNC Path

Aug 19, 2009

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.

VS 2010 - Timer To Check If Directory Exists

Jun 2, 2011

I 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..

VS 2010 FtpWebRequest - Check Directory Exists?

Oct 26, 2010

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:

[code...]

I have attempted to modify this with ListDirectory in place of GetDateTimestamp (to check if a directory exists) but it seems no exception is thrown whether the directory exists or not. I've done lots of Googling but haven't found a satisfactory answer.
