Hi i have developed an application in vb.net
i am creating directories at runtime in c:\programfiles\
it is possible in Windows XP.
But in vista, it is creating a problem.
it is not creating a directory.
i think it is problem of permissions.
does any one knows how to set permissions to a folder in Vista
to create directory and file under that folder.

The user will have to right click the program and select "Run as Administrator", or your application manifest file will have to request Administrator Privileges at runtime. This is also assuming that the account that the user is running the application from has Administrator privileges. Both of the above options will also pop up the ugly UAC dialog boxes.
All in all, I would suggest you find a way to program your application without it needing Administrator privileges.
I hope this helps.

Hello all, I'm trying to develop an application to read your emails using a pop3 address, but if the mail provider is, for example, gmail, it will need to connect using SSL, right? But I really don't know how to do that... I'm so lost... Any help?

Well, that component is not free... I was looking for a way to connect to a SSL server using sockets...

i have looked in my books, I have looked online, I have looked in code Project. Why can't I find this simple answer to my question. I must not be working it correctly on the search engines. Maybe someone here can help me.
Here is goes. This should be a no brainer.
I want to write to a file. I want to put a literal " in the string. How do I do that in Vb .net?
I tried """ with no luck.
So, does anyone know this answer that I should probably be able to recite in my sleep.

try adding an extra ":
stream.write("""")
will write "
and
stream.write("""Hello""")
will write "Hello"

Use 4 double quotes. One for each of start and end of string, 1 as an escape character and 1 for the string content. Great syntax vb uses here!

In addition to the above posts, if you have to add a lot of quotes as you are creating a string, I would suggest creating a quote String and then just add it wherever you need a quote.
Dim quoteStr As String = """"<br />
MsgBox(quoteStr + "Hello" + quoteStr)
It makes it easier to read if you are working with lots of strings.

You can also do Chr(34) where you want the quotes.
MsgBox(Chr(34) & "This is in quotes." & Chr(34))

But that's just nasty as all hell, obviously.

When I am not in C# I still use the Convert.ToChar(10)+Convert.ToChar(13) for a return/newline character.

Hi All, I am working on a VB.Net and SQL Server application. In order to implement Inter process communication, I am using a FileSystemWatcher object to read a text file, which gets updated by other application. When Application A makes any changes it updates FileWatcher text file which triggers an event in Application B.
But when event occurs, I get following error :
'The process cannot access the file 'C:\Program Files\Pimps\Session\UserSession.ini' because it is being used by another process.'
Can anyone guide me how to implement file sharing by using FileSystemWatcher. Many thanks
Public WithEvents Watcher As IO.FileSystemWatcher
Watcher = New IO.FileSystemWatcher
Watcher.Path = 'C:\Program Files\Pimps\Session' 'File location
Watcher.NotifyFilter = IO.NotifyFilters.LastWrite Or IO.NotifyFilters.Size
Watcher.Filter = "UserSession.ini"
AddHandler Watcher.Changed, AddressOf OnSerializedFileChanged
Watcher.EnableRaisingEvents = True
Private Sub OnSerializedFileChanged(ByVal source As Object, ByVal e As IO.FileSystemEventArgs)
Dim strUser As String = ""
Dim iStart As String
Dim iEnd As String
Dim iType As String = ""
Dim arLine() As String
Dim sr As System.IO.StreamReader = Nothing
If File.Exists(UserInfo) Then
Try
sr = System.IO.File.OpenText(UserInfo)
Dim MyContents As String = sr.ReadToEnd
sr.Close()
sr.Dispose()
arLine = MyContents.Split(Chr(13))
For i As Integer = 0 To arLine.Length
If InStr(arLine(i), "ContactId:") > 0 Then
strUser = arLine(i)
If strUser.Length < iEnd Then Exit Sub
iStart = InStr(strUser, "ContactId:") + "ContactId:".Length - 1
If InStr(strUser, ",") > 0 Then
iEnd = InStr(strUser, ",") - 1
iType = strUser.Substring(iEnd + 1, 1)
Else
iEnd = strUser.Length
End If
ContactId = strUser.Substring(iStart, iEnd - iStart)
If iType = "N" Then 'if a new contact
Me.Invoke(dLoadContact, ContactId)
Me.Invoke(dLoadRecentlyCreatedContacts)
Else
Me.Invoke(dLoadRecentlyModifiedContacts)
End If
Me.Invoke(dMinimizePimps)
Exit Sub
End If
Next
Catch
pimForm.pimMsgBox("Error while reading recent contact list:", Err.Description, frmMsgBox.pimIcon.pimError, frmMsgBox.pimButton.pimYes, "OK")
Finally
sr.Close()
sr.Dispose()
arLine = Nothing
End Try
End If
End Sub

It's tripping up over the file lock, e.g. while one process is writing to the file, the other process is trying to read it before the first process has closed the fs stream. You need to wait until the file is closed before responding the FSWatcher change event, but this just introduces a whole host of other problems!
I suggest you try using another method for inter process communication here (just type that into google for some options) as there's no easy way to synchronise the file access across 2 processes. Try finding an example that does this using Sockets or NamedPipes or Remoting.
