well, they already did the code for the open/save dialog boxes. i forget the exact code as i have only dabbled in vb for a little while, but if you want, i can look at my old work.

but, this dialogue box is only a fancy way of getting a filename, after that, your open/save code must read/write to that file.

simply and naively, this can be done with

Dim NextLine As String
On Error GoTo ErrHandler
Open InFile For Input As #1
Line Input #1, NextLine
Close #1
Exit Sub
:ErrHandler
MsgBox "you did something wrong", . . .
End Sub

for writing:

Dim NextLine As String
On Error GoTo ErrHandler
Open OutFile For Output As #1
Print #1, "foo"
Close #1
Exit Sub
:ErrHandler
MsgBox "you did something wrong", . . .
End Sub

this means of writing/reading is machine dependent, meaning windows will output \r\n for newlines, unix \n, macs \r. and inputting will only read until it reaches \r\n, \n, \r depending on os. this really does not matter (but, in my case it did).

there is probably a better way of doing this. check out some vb boards. that is where i got my help.

oh, silly me.
this is using the built in "File" control widget do-dad. these are added just like buttons, lists, radios, etc.
