Hi - I am playing around with a program with which I use Selenium
Webdriver's c# binaries. I am using the following setup: Win7 64
bit, Visual Studio 2010. My program is written using Vb, and I use the
webdriver c# binaries to interact with Firefox. I am not using Nunit
or a testing framework.
here's the problem. I am testing interacting with Google as per the
example in the documentation. if for some reason i switch the website
in the browser and then run the same code, then obviously since there
is no element named 'q', it causes an error. However, it doesn't seem
to throw a catchable error even though i put a try/catch around it.

Is there a way for me to catch this or other errors within my VB
code? The problem is that it seems like it brings my app to a
grinding halt - it cannot recover from this.

Any help appreciated in advance.

Michael

Ensure that you exception catching is wrapped around your Find
method.
Could you reply with a code sample where the exception is not being
caught? It may be easier to assist that way.

Nathan,
Thank you for your reply. Below is the chunk of relevant code. The
subroutine testSelenium2 is executed first by pressing a button on the
form. Then the subroutine testSelenium3 is executed by pressing a
different button on the form.

Thanks,
Michael

iQuery = x.FindElement(By.Name("q"))

iquery.SendKeys(Keys.Enter)
End Sub

Private Sub testSelenium3() Try iQuery =
x.FindElement(By.Name("q")) iQuery.SendKeys("Cheese" &
Keys.Enter) Catch ex As Exception MsgBox("error")
End Try End Sub

End Class

Here is some additional information about the error it generates in VS
2010 (VB). It seems like it is trying to find the source code for the
C# Dlls to debug through? All I downloaded though was the window
binaries. I am running my project in debug mode. Do I need to
download the source code to go any further? I just want to catch the
error. I know what's causing the error - trying to find an element
that doesn't exist on the page - but I just care about catching the
error so I know that error occurred and allowing the vb program to
continue without failing or freezing. Error information below.
Thanks,
Michael
