vb 6.0 project help

Posted 15 February 2010 - 07:17 PM

Hey guys i have a vb project due in real soon and i really need some help. The premise for the project is a holiday booking program. The user can select a holiday on one form and optional extras on another form. My main problem is that i just dont know how to carry the total of the cost of the holiday over to the extras form and from there to the finalisation form. My code for the holiday form is this:

Private Sub TxtAdults_Change()
TxtAdults.Text = InputBox("Please input number of adult tickets needed.")
End Sub

Private Sub TxtKids_change()
TxtKids.Text = InputBox("Please input number of kids tickets needed.")
End Sub
Private Sub LblTotal_Click()
LblTotal = (LblAdultPrice * TxtAdults) + (LblKidsPrice * TxtKids)
End Sub

Private Sub Cmd_Extras_Click()
Frm_tours.Hide
Frm_Extras.Show
End Sub


Basically i want to carry the amount on LblTotal onto my next form. How can i do this?

Thanks Guys.

When I enter Frm_Extras.intTotal = Frm_tours.LblTotal.Caption, I keep getting an invalid outside procedure error.

Hi,

Here is my simple help.

On your Frm_tours use the below code

Option Explicit
Public strAmount

On Unload/any event you type the below code.

strAmount = LblTotal.Caption

Then on your Frm_Extras use the below code

Private Sub Form_Load()
intTotal = Frm_tour.strAmount
End Sub

Hope this helps

hello :)
@Kinwang2009
i think that when you unload the form variable strAmount will be empty.
@Guest_Fortran
if you want to pass the value to a new form try this add a public variable in the new form like so
Option Explicit
Public MyVar as String


then in the old form when you call the new form
Dim MyNewForm As New My_New_Form
MyNewForm.MyVar=Label1.Caption
MyNewForm.Show


good luck

Actually NoBrain, when you unload a form, you are only unloading graphical elements of the form, which means any procedures or variables that are public are still available. For an example start a new standard exe program, add a button to form1 (command1) and add the following code...
Option Explicit

Private Sub Command1_Click()

On Error GoTo Command1_ClickError

Form2.Show
Unload Form2
MsgBox Form2.MyPublicForm2StringVariable
Set Form2 = Nothing
MsgBox Form2.MyPublicForm2StringVariable

Exit Sub
Command1_ClickError:

MsgBox "Command1_Click " & Err.Number & ":" & Err.Description

End Sub


Now add a form (form2) and add the following code...

Option Explicit

Public MyPublicForm2StringVariable As String

Private Sub Form_Load()
MyPublicForm2StringVariable = "This is a test"
End Sub


Press F5 to run and click on command button...



Good Luck
