End If

It depends are you looking for any spaces including appearing between words (if so see above post) or are you validating that the textbox doesnt contain only spaces? If the latter try the following.

    [COLOR="Blue"]If [/COLOR]TextBox1.Text.Trim.Length = 0 [COLOR="blue"]Then[/COLOR]
        [COLOR="SeaGreen"]    'Text box is empty of any text[/COLOR]
    [COLOR="blue"]End If[/COLOR]

Just put the next code into the button part:

If TextBox1.Text.Contains(" ") = True Then
MessageBox.Show("You have spaces")
ElseIf TextBox1.Text.Contains(" ") = False Then
MessageBox.Show("You have no spaces")
End If

You can always edit the text for other functions.

No reason to check twice....

    [COLOR="Blue"]If [/COLOR]TextBox1.Text.Contains(" ") = True [COLOR="blue"]Then[/COLOR]
        MessageBox.Show([COLOR="Red"]"You have spaces"[/COLOR])
    [COLOR="blue"]Else[/COLOR]
        MessageBox.Show([COLOR="Red"]"You have no spaces"[/COLOR])
    [COLOR="blue"]End If[/COLOR]

True, I'm sorry but I'm quite new to VB

No problem, just pointing out different ways of doing things. I come here for the same, to learn from the differences of others
