VB.NET: Transferring Data From Form to Form....[Resolved]

[toytoy]

Does anyone have any idea how to transferring data from TextBox1 in form1 to textBox2 in form2.....

That means after i fill in any data in textBox1 and click Next button...

It will bring me to form2....and there the data that i key in form1 will appear to form2 in textbox2


Thanks

'in form1
public s as string
s=textbox1.text
dim f as new form2
f.showdialog
 
'in the form2
dim f1 as new form1
textbox1.text=f1.s

[toytoy]

still cannot....

TextBox1 in form2 got an error say not declared yet..

[mar_zim]

you must draw a textbox in design mode of your form2.

i just assume that you have a textbox named textbox1 in your form2.

[toytoy]

you means both form1 and form2 share the same TextBox1....

Even if i do the above, textbox1 in form2 will still be blank without the error message...

[mar_zim]

ok lets do it this way..

'i declare public variable so that it can access through out the project when you instantiate the form.
'in the form 1
public s as string
'lets assume that you have a textbox in form named: textbox1
'in the button click event
s=textbox1.text
dim f2 as new form2()
f2.showdialog()
 
'in the form2
'lets assume that you have a textbox named: textbox2.
dim f1 as new form1()
me.textbox2.text = f1.s

i hope that make sense..

[toytoy]

Thanks.....but still cannot...

I think because you declare too much New in form1 and form2...

That why......form2 will always be blank...

[brown monkey]

perhaps search?

[mar_zim]

you cannot use the form if you will not instantiate it.

that's the purpose of New.

hey toytoy...how about this..
in form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim f As New Form2()
        f.TextBox2.Text = Me.TextBox1.Text 'passing text in the form2
        f.Show()
    End Sub

[toytoy]

got it finally....


Thanks fret

Beside passing data directly from textbox....

Could it be possible if i use string to transfer data in the same Scenario as above....

Thanks

yes...you are essentially doing that by transferring textbox to textbox

[toytoy]

for the string part...i solve it with:

Dim s As String
Dim f As New Form2
s = textBox1.Text
f.textBox2.Text = s     'passing text to form2
f.Show()
Me.Hide()

Now another problem is i am using the owner thing..

Which means in form1....

Private f As New form2
Dim s As String
Private Sub btnNext_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNext.Click

s = cbo.SelectedItem
f.textBox2.Text = s 'passing text in the form2
f.Show()
Me.Hide()
End Sub

In form2.......

Private Sub btnBack_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnBack.Click
Me.Owner.Show()
Me.Hide()
End Sub

Which means i cannot use the f.textbox2.text = s in form1.....the program will get hang there for quite long before getting the data there when i run...

[toytoy]

oh....

forget that i put something in form2 loading part..

The program can still be works with the owner thing when i delete that part in form2 loading..

[fret]

Private Sub btnBack_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnBack.Click
Me.Owner.Show()
Me.Hide()
End Sub

dunno this part, you mean you want to go back to the form who opens the form2? is that?

[toytoy]

yeah.... it' s also must be able to click back

but i want to use string and send over to another textbox in form2...

the string are from Xml...

that' s why i am using LoadXml() to load the string from form1 and then show it to the textbox in form2

[fret]

why don't you change it in this way, just a suggestion.
in form1:

'next button
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim f As New Form2()
        Me.AddOwnedForm(f)
        f.TextBox1.Text = Me.TextBox1.Text
        f.Show()
        Me.Hide()
 
    End Sub

in form2:

Dim f As Form1
    'back button
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        f = Me.Owner
        Close()
        f.Show()
    End Sub

[toytoy]

For the owner thing...

say i want to click back...how to i actually clear the listbox items in previous form...

Thanks

add this on the button back...
f.ListBox1.Items.Clear() before showing the owner form.

[toytoy]

Cannot....

f.ListBox1.Items.Clear()

the f is not declared in form2...

[fret]

hey sorry for that because i considered the code above i suggest and add the f.ListBox1.Items.Clear(). Just try the code i suggest and it works well.

[toytoy]

oh.....its alright...

i just change and add in the title where the owner thing starts...

i hope....it will not confuse you guys which method i use..

[fret]

no problem...
happy coding

[toytoy]

finally, i solve it....

i put the clear() thing in form1...

that means i clear the listbox first before going to form2..

thus, when i click back....all are clear already...

[fret]

like what you've said you know there a lots of way on how to come up with. It's up to you on what would be the better.
ok, put [solved] or [resolved] to your topic.
cheers mate.
