    Loading and unloading forms

    VB6. When selecting from drop down menu options I display different forms by
    using the Load (filename) and leave the form with Unload(Filename )



    The Load event allows me to program the opening of a particular direct
    access file and the Unload event lets me program the closing of the file.
    Things are kept 'tidy' this way.



    My problem is that I want to pass in a parameter when a particular form
    loads. This will control which record is to be displayed. I want Pointer
    to come in as a parameter.



    Eg Seek #1, Pointer

    Get #1, , MembRec



    How do I do this?

    Your help is appreciated



    Geoff

      I would create a public method in the target form, and put the file opening code
      in that instead. Something like
      Public Sub InitForm(Pointe r As Long)
      ' open the file...
      ' seek for pointer...
      ' get the data....
      End Sub

      Then in the menu code of the main form, do
      Load frmTarget
      Call frmTarget.InitF orm(27)
      frmTarget.Show

      The parameters can be any type you need.

      By the way, you should use FreeFile to get a file handle, not hard-code in #1,
      as in
      nFile = FreeFile
      Open "filename" For Random As nFile
      Seek #nFile, Pointer
      ' etc

          put the code in a .bas file that way it only has to be coded once rather
          than on each form. this will also solve your problem by calling things from
          the .bas file on form load.
