[RESOLVED] How to set Minimum character[HELP]

[x DeaDLy]

How would i set a minimum number of characters in textbox1 for a button to work. and if the person does not enter the minimum number of characters, a messagebox pops up sayin something like "need at least 5 characters!" Thanks

Set the button initially to disabled and try this:

Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
        Me.Button1.Enabled = (Me.TextBox1.Text.Length > 5)
    End Sub

A MessageBox coming up would be really annoying I think from a UI point of view. That said, you could make it so when they click the button it checks the textbox length and then shows the MessageBox.

I agree with ForumAccount. The app that I'm currently working on has many of these cases where controls switch from Enabled to Disabled. I think it looks smart.

Or

if len(textbox1.text) < 5 Then
Button1.Enabled=false
Else
Button1.Enabled=True
End If
