Hi all,
My first venture into the use of webBrowser control.
I am writing an application that will enter some values in a (local) web site.
It is really pretty simple in concept. The data will be scanned from a card and
I need the web site then to process the data. I have most of this working. I
set up a webBrowser control which logs onto the web site and then navigates to
the correct web page and awaits the data entry.
My issue is that I get a runtime error when I am logging on to the site. Below
is the code to logon - the error is thrown when on the "mi.Invoke(obj, new
object[0]);" line.
I tried wrapping this in a try/catch block but this does not catch anything.
HtmlElement username = this.webBrowser1.Document.All["txtUserid"];
username.SetAttribute("value", "usr");
HtmlElement pass =
this.webBrowser1.Document.All["txtPassword"];
pass.SetAttribute("value", "usrpwd");
HtmlElement el = webBrowser1.Document.All["btnSubmit"];
object obj = el.DomElement;
System.Reflection.MethodInfo mi =
obj.GetType().GetMethod("click");
mi.Invoke(obj, new object[0]); // <--------- error
thrown here.
The error is: " A runtime error has occurred. Do you wish to debug? Line 157.
Error: Object expected." (Yes & No buttons) If I click No, everything
proceeds as normal
Line 157 is nowhere near this and I cannot see how it is at all related.
If I click Yes to debug and use the Microsoft Script Editor, I seem to be taken
to the web page code which shows this:
<INPUT type="image" NAME="btnSubmit" src="/xyz/images/Submit1.gif"
width="98" height="24"
border="0" alt="SUBMIT" onClick="return fclick();" />
with the " return fclick(); " highlighted.
Can anyone suggest what I can try to sort this out?
Cheers,
Michael King
