WebBrowser - Check If Field Name Exist
Apr 21, 2009Basically I just want to set up exceptions for my program to prevent errors. The problem I am having is that sometimes the field name does not exist. For example, I am setting focus to the username text field named simply "username". However, if the entry does not exist (name=username) then I get an error. So what I need is a simple if statement to determine if it exist beforehand.
If Webbrowser1.Document.All("username").Exist Then
WebBrowser1.Document.All("username").Focus()
else
Messagebox.show("Field was not found!")
End If
