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

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

VB Code:

'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

still cannot....

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

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

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

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...

ok lets do it this way..

VB Code:

'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..:wave:

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

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

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

perhaps search?

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

that's the purpose of New.

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

VB Code:

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

got it finally....


Thanks fret

:lol:

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

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

Code:

---

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....

Code:

---

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.......

Code:

---

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...

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..

:wave:

---

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? :)

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

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

VB Code:

'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:

VB Code:

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

:afrog:

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. :afrog:

Cannot....

f.ListBox1.Items.Clear()

the f is not declared in form2...

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.

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..

no problem...
happy coding :bigyello:

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...

:wave:

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