Hi, Sorry for the subject but I didn't know what better to put...

Well, I have a register form in my vb and I'd like to know how to put this:
If when a user click register and in webpage appears a text saing; your username is invalid. choose another one.

The webbrowser is hide in the form, because I 'redirect' the white spaces to textbox's and submit button to a button1.

I'd like to know how to inform that user (with a msgbox or something) that his username is invalid. How to do this ?

Sorry my english :s

EDIT: here is the register webpage: http://patrickcosta.forumeiros.com/regi ... rue&step=2

something like this:

Code: Select all

if webbrowser1.documenttext.contains("Your username is invalid") then
    webbrowser1.visible = false
    msgbox("The username/password is invalid")
end if

You can put the textboxes and the submit button behind the web browser.

i think you can use the code i gave you in the web browser's page_load (or something like that) event.

Actually, you might want to place it in the WebBrowser DocumentCompleted event so that it executes the code when the page has finished loading.

Code: Select all

Private Sub WebBrowser1_DocumentCompleted(ByVal sender As Object, ByVal e As WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
   If WebBrowser1.DocumentText.Contains("Your username is invalid") Then
       MessageBox.Show("The username you chose is invalid")
   End If
End Sub

Something like that I guess

Private Sub WebBrowser1_DocumentCompleted(ByVal sender As Object, ByVal e As WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
   If WebBrowser1.DocumentText.Contains("Your username is invalid") Then
       MessageBox.Show("The username you chose is invalid")
   End If
End Sub

Something like that I guess

Using this code it will search "Your username is invalid" every pages or only in the first ?

Thanks everyone

EDIT: I tested now and was this I was searching!
