[RESOLVED] [02/03] Class variables for pathway

[lionelnz]

I am trying understand why my "path" variable will not work for File/OpenText etc yet my "f" & ''fn" variables work together. I have the following code in above the FormLoad window.

Dim fn As String 'Filename that is being manipulated
  Dim f As String = ("C:\71151A2\")
  Dim path As String = f & fn

If i use

fn = "PHONELISTS.TXT" 'File with phone directories
    sr = File.OpenText(f & fn)

The code finds the file but if I use "path" in place of "f" & ''fn" it won't find it! Any clues as to why. I have declared the variable again in the sub procedure.

Please do not create duplicate threads. They are a hindrance to the smooth running of the forum and they don't help you in any way.

After executing this code:

Dim fn As String 'Filename that is being manipulated
  Dim f As String = ("C:\71151A2\")
  Dim path As String = f & fn

the 'path' variable contains the string "C:\71151A2\". After that, setting 'fn' to something has no effect whatsoever on 'path', so after this code:

fn = "PHONELISTS.TXT" 'File with phone directories

'fn' contains the string "PHONELISTS.TXT" but 'path' still contains "C:\71151A2\". Had you used the debugger to check the value of path when you were using it you would have seen that.

Apologies for this I do not know how this happened. As for the debugger sometimes it works & sometimes it doesn't. I appear to have some minor gremlins that are inconsistent & intermitten with my system & produces unexpected & unusual results.

As to "path" explanation, I did see that but what I do not know is why!!!! ,because I Dim path = f & fn (which work by themselves).

Now I see!!!!! Thankyou

Rest assured I have appreciated your help very much to a newbie who knows enuff to be dangerous!
