Code: Select all
If TextBox1.Text <> Nothing Then
'Textbox contains something
Else
'Textbox is empty
End If
Or
Code: Select all
If TextBox1.text.lenght = 0 Then
'Textbox is empty
else
'Textbox contains something

Code: Select all
if textbox.text = "" then
msgbox"text box does not contain any text"
as an example.

Code: Select all
If (TextBox1.Text + TextBox2.Text + TextBox3.Text + TextBox4.Text + TextBox5.Text).Contains("letters") Then
End If
And yes, you would be able to check if the captcha is correct your way.
