Reading text from a file

I'm not very familar with vb but you are reading the first line and then the second one and save this into a variable:

sr.ReadLine()

MyFolder = sr.ReadLine

just leave the first readline and you can read the first line. Also I think if you want to move the folders that are defined in your text you should put that in your loop,too.

Replace ;

Dim sr As StreamReader = New StreamReader(MyFileToRead)

Using sr As StreamReader = New StreamReader(MyFileToRead)
'Process sr
End Using

I have just tried out your suggestion, and i seem to be getting an exception error during debug at the point where it is declaring sr as the streamreader.

The error that is showing is...

Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

I do have Administrator rights on my PC, and all files referred to are on local drive c:

Have you any ideas what I am missing? I have added a line "imports system.security.permissions.fileiopermission" however just clutching at straws here.

Thanks

Andy

Just to add, I have also tried the Using/End Using but this also has the same error on the same line.

Thanks Grant,

I have tried what you suggested, although the error is occuring before i get to the command. However I have but the True at the end. The destination folder did have a folder in.

It still gives the security error.

This is the exact error

Hi,

Yes, I am running Windows XP, but as for the file encryption, there is nothing that i have specifically encrypted or should I say, nothing that i am aware of :-)

Would this be specific software that i will have had to install such as PGP? If so, there is definately nothin like that installed.

The text file I am trying to access is local, the only other thing i can think, is that the project itself is saved on a network storage drive on another server, although like i say, the files and folders that the project refers to is all on my local laptop.

Glad you got it sorted Andy.
