Please help with passing data from one form to another form

[wisorac]

Hello!
I have a project to where I am making a pizza order for customers. My forms consist of a form for the pizza quantity and size (the cost is displayed in a lblDisplay.Text). I also have another form which calculates the cost of beverages.

I am now on the third form which calculates the cost of side items. I need to make it to where when the user clicks the submit button that the total of the side items is displayed along with adding the total of the pizzas and beverages of the other two forms. I dont know how to grab data from other forms.

I can make the other forms load by using the

Dim XXXX as new frmXXX

If my question is not clear enough, please let me know.

Hi Adam,

I will give the method , regardless about your project take the method then apply it with any project

There two common methods is used for passing data between forms

The first one is by creating a properties in the form that you want to pass the data on it

for example if you have two forms the the first one (name it Form1) include one textbox control and button , and when pressing button you want to pass the textbox text to the second form (name it Form2)

the property shold be like :

Note these codes in Form2

Private _passedText As String

Public Property [PassedText]() As String
            Get
                Return _passedText
            End Get
            Set(ByVal Value As String)
                _passedText= Value
            End Set
        End Property

Then , when you are declaring Object from Form2 you just set The Value before Showing the Form

in the Form1 and in Button1 Click event write these lines :

Dim Obj As New Form2
Obj.PassedText = TextBox1.Text
Obj.Show

by this way you have the text in the Form2 - variable _passedText

hope you get it , if you didnt I am here

The Second Method by Adding parameters to the Form that you need to pass the data on it in Sub New - I didnt like it , the Properties is better

Good Luck

Hi Ammar Gaffar,

If I want to pass around 10 data from form1 to form2, it iz I still can using this method? or got other method to pass more than 1 data from form to form?

[Ammar Gaffar]

Hi KhWo ,

It dosnt matter how many Variables you need to Pass , just create a property for each variable , Object , or any other types

Good Luck

Do this also work in VB 6? I'm new to the language and tested out your code but I only experience alot of failures.

Thx

in vb 6 you can access it directly

[Zhoot]

Thank you!

So if I create a variable in Form1, then it will automatically exist in Form2 once it opens? Cool!

[fawadkhalil]

Obj As New Form2
Obj.PassedText = TextBox1.Text
Obj.Show

Hi i tried this code and it really works.But without obj.Show it didnt.
Whats the function of this line of code?
