Textbox Lock

[Emerican]

I haven't been using Vb.net in a while and was wondering just how to lock a textbox for input.
ie in vb6

textbox1.locked = true

[robymix]

To prevent a textbox from receiving input then use:

TextBox1.ReadOnly = True

Yes, and if you want to to avoid it becomes gray, choose explicitly the background color (for example: White).

or TextBox1.enabled = False

Problem with that is if you need to scroll or copy data out of the textbox. By setting ReadOnly = True, you can still scroll and copy, just not paste or edit the text.

hi there,
I'm wonder how to make it possible:
Click on command1, Controls gone Lock,
Click on command2, Control came alive (unlock),


----- dont say it like that : textbox.txt.lock = ture

I want to make all controls on form 'Lock' on single click..

plz help

Depends on the controls you're using. You could make a foreach loop to look for Command buttons and set their Enabled property to False. For TextBoxes, set them to ReadOnly.

Control.Lock does not have any effect at run time. It is a design time only property and setting it to True prevents you moving the control in the designer. All controls have an Enabled property and you can set its value in code whenever you like. To enable and disable multiple controls it is easiest to put them all in the same container, like a Panel, and just set the Enabled property of the container. Note that is still possible to have another control, like the button you want to use to toggle the Enabled state, show over the container without actually being in the container by manipulating the z-order.

Didn't get yet.. Can't understand,
write code please..

[Kasracer]

Dim t As Control
        For Each t In Me.Controls
            If TypeOf t Is TextBox Then
                t.Enabled = False
            End If
            If TypeOf t Is Button Then
                t.Enabled = False
            End If
        Next

Something like that should get you started.

Make sure you copied my source code correctly.

You may want to look into getting a VB.Net book.

Use true instead of false

Just make sure you leave the unlock button enabled
