Retrieving data from register

[Michel Vanderbeke]

Hello,

When I want to retrieve data from the register, the defaultvalue doesn't
seem to work correctly.

iCounter =
CInt(My.Computer.Registry.Getvalue("HKEY_LOCAL_MACHINE\Software\MyProg\Settings",
"Articles", "80"))

Is it correct that when the entry in the register does not exist, the string
"80" is taken as default?
This does not seem to work with me.
When the key Articles doesn't exist, there is no error and iCounter is set
to 80.
When the key Settings doesn't exist, there is sometimes an error and
sometimes iCounter is set to 0.

Does anyone have any idea what goes wrong?

Many thanks,

Michel

Hi Michel,



It's entirely possible you can determine what is going on by breaking down
your code into more readable chunks. Does the key "Settings" exist? What
about "MyProg"? Either way, its easier to see what is going on with
something like:



Dim theValue As String =
My.Computer.Registry.GetValue("HKEY_LOCAL_MACHINE\Software\MyProg\Settings",
"Articles", "80").ToString()

If theValue Is Nothing Then

' The key or part of the path does not exist

Throw New Exception ( .... )

End If



Dim theResult As Integer

If Not Integer.TryParse(theValue, theResult) Then

' A value was returned but it wasn't an integer...

Throw New Exception ( .... )

End If
