Using a label to show textbox data

Hey, great forum you have here.
Does anyone know how to make label1 show the data in textbox1? I simply can't figure it out.

Value of type 'System.Windows.Forms.TextBox' cannot be converted to 'System.Windows.Forms.Label'.

Thanks for the help in advance :~)

You are probably writing "textbox1" instead of "textbox1.text"

Here is the right code:

Quote:

---

label1.text = textbox1.text

---

Remember, when wanting to refer to a string in a textbox(or any control with text in it), write ".text" after the control's name

It sounds like you are referring to the controls directly instead of their Text properties.

Label1.Text=TextBox1.Text

Hey Leisure Jinx you owe me a coke.

What a prompt response, thanks guys! One more problem. The label does not seem to update as the textbox does. (it compiles properly)

As in, I type in the textbox, nothing appears in the label.

Any solution?

Label1.Text = TextBox1.Text

VB is an "event-driven" programming system - code is basically executed in response to events raised by user interaction.

In order for the label to keep updating you need to respond to the event that is raised when the user changes the contents of the textbox. Using that single line of code doesn't in any way link the two controls - you need to keep the two in synch manually.

If you double-click on your textbox in the form designer it will open a code window and create a procedure "textbox1_textchanged" which handles the textchanged event of the textbox, so you want to put your code to update the label in there :

Code:

---

    Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged

        Label1.Text = TextBox1.Text

    End Sub

Beautiful, thanks a bunch! I appreciate it!

EDIT:
I thought of one more, perhaps more complicated idea. If the text put into the label is large (extends beyond X amount of characters), would it be possible to add an ellipsus in there and cut off the rest of the text? For instance, lets say I want my label to support 10 characters only. The textbox has "Lorem Ipsum etc;" the label would show "Lorem Ipsu..."

Bumping for the update, sorry. I'm afraid it wont be seen as I marked it as solved.

Yes thats perfectly possible... think about it logically and it should be obvious what you need to do.

NB if you've marked a thread resolved you can un-mark it resolved using the same menu, however as you're now asking a new question you should really post this as a new thread.

Change the "autoellipsis" property of the label to "true" , and the "autosize" to "false" OR, put this code into the Form Load event handler, I've changed those properties for you here:

vb Code:

Label1.AutoEllipsis = True
Label1.AutoSize = False

I suggest you spend a few hours just playing with the properties, you'll learn a lot.

I was playing with If len > statements and decided to refresh this thread to see if there was any more help. I had no idea that this was a default property.

I feel idiotic not knowing that this was a default property. Regardless, thanks for the assistance, guys!

Unfortunately using the auto-ellipsis property wont help if you explicitly want to limit the label to 10 characters as it works purely on screen size not the number of characters (unless you use a non-proportionally spaced font like courier and set the label up to be 10 characters wide).

EDITed some minor bugs... Use this one


Oh, sorry, sorta overlooked this part, TY

You were right about using the If, Then, statements... Here is the edited code to put in the textchange event handler

vb Code:

Dim mcl As Integer = 10 'Replace this with max char. length
If TextBox1.TextLength > mcl Then
Label1.Text = (TextBox1.Text.Substring(0, mcl) + "...")
ElseIf TextBox1.TextLength <= mcl Then
Label1.Text = TextBox1.Text
End If

Oh, and change the AutoSize property back to true
