Hi guys,

This is my first thread here so I'll first of all say hello to everyone!

I'm not sure if this is the proper section of the forum for this question...if not I'm sorry.

My problem is the following :

I am trying to get the status of Exchange Cached mode for MS-Outlook for a remote PC using VB.net. So far, I have found this.


VB.NET:
 mstrHostName = HostNameTextBox.Text 
 
Dim MyReg As Microsoft.Win32.RegistryKey = Microsoft.Win32.RegistryKey.OpenRemoteBaseKey(Microsoft.Win32.RegistryHive.CurrentUser, mstrHostName)
 
Dim MyRegKey As Microsoft.Win32.RegistryKey
 
 
 
Dim MyVal As String
 
 
 
Dim strProfileName As String = InputBox("Please input Profile Name", "Profile Input", "Default")
 
MyRegKey = MyReg.OpenSubKey("Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\" & strProfileName & "\13dbb0c8aa05101a9bb000aa002fc45a")
 
MyVal = MyRegKey.GetValue("00036601")
 
MyRegKey.Close()
 
If MyVal = "04 00 00 00" Then
 
 
 
RichTextBox1.Text = "Exchange cached mode is disabled for profile " & strProfileName
 
ElseIf MyVal = "84 01 00 00" Then
 
 
 
RichTextBox1.Text = "Exchange cached mode is enabled for profile " & strProfileName
 
ElseIf MyVal = "84 05 00 00" Then
 
 
 
RichTextBox1.Text = "Exchange cached mode is enabled with public folders and favourites for profile " & strProfileName
 
End If


When I put in the remote hostname, it should prompt the user to input the Outlook Profile to look up. Then, using about the same code, with another button, I could either turn on or off the cached mode.

But when I click on the button to get the status, I do get prompted for a profile name. But then, I get his error at the registry key lookup :



VB.NET:
