VB 6 Help with global variables

[davros]

I have 2 forms the main form + a search form which is loaded when the user selects search from the menu of the main form..

in the code of the main form i have:

Public intindex As Integer

in my search form i have the following function :

Private Sub LstList1_Click() 'GO BACK TO PARENT FORM
intindex = LstList1.ListIndex
Unload Me
frmCourseManager.Visible = True
End Sub

when i compile the program i get the following error message :

Compile Error Variable not Defined - intindex

i know when i last ran the program in 2000 it worked fine but now i get the above error could this be a compatability problem ?
it worked fine in 2000 with windows 98 but now im using windows xp

thanks in advance.....

It has got something to do with compatibility, i had this problem myself.
However, this was because i hadn't Dim'd the variables i had put into the script.

As far as i can tell, this problem is caused because you defined Intindex on a different form to the one that accesses it.
I found a way to fix this but can't for the life of me remember what it was.

Aha! This is a possibility:
When the form Unloaded itself, it may have lost the data it held (i.e Intindex)
I would suggest TRYING Instead of using:

Unload Me

use

SearchForm.Hide
(presuming you replace search form with the name OF your search form :p

I really hope this helps in some way :)
Sorry if it doesn't, i hope you solve your problem

Hi.....................

Define ur public variable in the Module.

or remove the tag of Option Explicit in the top of ur form.

Hi,

From what I saw, you have declared a variable named intindex in lets say frmMain and are accessing it in the form named frmSearch.

Since you have declared the variable in the form module that is frmMain, it is accessible to the procedures written in frmMain only even if it is declared as Public. Insert a Standard Module and then declare this variable as Public there. It will be available to all the forms in your project.

I have 2 forms the main form + a search form which is loaded when the user selects search from the menu of the main form..

in the code of the main form i have:

Public intindex As Integer

in my search form i have the following function :

Private Sub LstList1_Click() 'GO BACK TO PARENT FORM
intindex = LstList1.ListIndex
Unload Me
frmCourseManager.Visible = True
End Sub

when i compile the program i get the following error message :

Compile Error Variable not Defined - intindex

i know when i last ran the program in 2000 it worked fine but now i get the above error could this be a compatability problem ?
it worked fine in 2000 with windows 98 but now im using windows xp

thanks in advance.....

when you decare a public variable in one form and use it in another form you must use FormName.VariableName to find the varialbe from another form.

when you decare a public variable in one form and use it in another form you must use FormName.VariableName to find the varialbe from another form.

therefore you should declare variables which are used in severals forms in a module.
then make them 'public' or global (const)

[The Black Sheep]

This is THE best solution ever!
I had a different, yet similar problem with global variables.
They lost their value after an unknown period of time, but I declared them inside the same module as all my code.

My project got entirely undermined, since my global variable held the IRibbonUI reference to the WORD 2007 ribbon.
By putting all global (public) variables in a seperate module, they are more easy to find and their behaviour is more stable.


Thank you.
