copy paste

how to stop the copy paste in vb.net
one text box to another text box


thanks

Do you want to only stop copy/paste or any editing too? I don't see a reason.
To make it uneditable (which also prevents copy/paste), set the "Enabled" property of textbox to False.

i want to prevent the copy paste of password text and other inportant text boxes.
so i want to make a class and call it on text box in which i want to protect.

For password fields, it is the default behavior. i.e. Copying from password field is not allowed.
To set the textbox as password field, you may specify a PasswordChar="*" (or whatever you want) or set the property UseSystemPasswordChar=True

For non-password fields, set the ShortcutsEnabled = False
