.net - Check If A Directory Can Be Renamed?
Jun 29, 2009
My thought is to use CreateFile from kernel32 and check for sharing violations. I believe this will work because I watched the file system activity with Process Monitor while issuing a rename command from CMD that I knew would fail and the last activity was a failed CreateFile call that resulted in a sharing violation.This is the Process Monitor information on the call.
Desired Access: Read Attributes, Delete, Synchronize
Disposition: Open
Options: Synchronous IO Non-Alert, Open Reparse Point
Attributes: n/a
ShareMode: Read, Write, Delete
AllocationSize: n/a
Using this VB code, I produced a call which gave the same information in Process Monitor but did not cause the sharing violation.
CreateFile(theDirectoryPath, _
FILE_READ_ATTRIBUTES Or DELETE Or SYNCHRONIZE, _
FILE_SHARE_READ Or FILE_SHARE_WRITE Or FILE_SHARE_DELETE, _
[code]....
The constants are pulled from various MSDN and pinvoke.net sources.If I call the above code recursively on all subfolders it will eventually cause the sharing violation, but when CMD refused to rename, it did not recurse. Yes, I know I could just try and catch the exception. But the point at which I want to know if the directory can be renamed and the point at which I want to rename the directory are not the same.

when you start a new projekt, vs2010 makes a new folder for the projekt. when i reach a certain point in my projekt i want to save that version of the projekt.
what i do is make a new folder and copy that projekt to it. projektfolder2 . when i start the projekt in the new folder the sln doesnt work anymore. the vbproj works then. and vs 2010 makes a new sln file one directory down of the old one between the other
projekt files.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
My.Computer.FileSystem.RenameFile(Label1.Text, "Test.mp3") 'First renaming
System.IO.File.Copy(PATH OF TEST.MP3, Environment.SpecialFolder.System, True) 'But how I get the path of the renamed file (test.mp3)?
End Sub
Label1 = the file path that has to be renamed
"test.mp3" = the same renamed file
BUT how I get the path of the renamed file?

I'm using Linq to SQL, which generates partial classes and partial methods. You then extend that generated code by implementing your your customizations manually in another partial class. One of the hooks L2S gives you is the ability to implement partial methods that get called when a property changes. For example, if you have a property named "MyProp", then you can implement a partial method like so:

I want to have a windows application that would check a specific folder for any files, and if there are any files I will run some code to each file, I was going to use a timer and set it to refresh every 15 seconds or so but I am not sure if there are any other ways to do this that would not take up as much resources.

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.

Can someone tell me how to determine if an account is disabled in AD using VB.net 2008? I've looked at the "userAccountControl" property and this one seems to have it's flags changed when the account gets disabled.[code]I can't seem to figure out the proper statement to determine if the account is disabled or not. It doesn't seem to work out the same way as the lockout status.[code]

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..

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.

I'm copying over some files to a target directory on a daily basis.Before I move the new files over, I'd like to delete the old files under the target folder, possibly using System.IO.Directory.Delete()But my problem is, the target folder is on a public drive where everybody in the company could access, and I don't want to empty the folder while someone else might be using those files.I'm thinking whether there's a Class that check the status on the files in a specific directory before I come in and delete everything.(I know I would get an IOException if I disregard the status of the files and try to delete them)
