Weird problem w/webbrowser control

[J. Scott Elblein]

I have been using this code:

Dim ControlSet As HtmlElement = wbr.Document.GetElementById(ControlName)
          
wbr.Document.GetElementById(ControlName).SetAttribute("Value", Value)

in a program without issue for some time now. For some reason today however, whenever I access the same page that it has always worked on, now gives me a NullReferenceException error on the .setattribute line.

I am noticing when I hover the cursor over ControlSet after the Dimming, it says "Nothing".

Anyone have any ideas why this could be happening? Thanks.

Ignore this post please. I figured it out.

Please post your solution for others who may have the same issue.

May be he is passing ControlName instead of passing ControlId

The solution was, i was being a big fat dummeh, lol

The site I was using it with, which hasn't changed a single thing as far as the login goes for years, suddenly changed the id name that i was looking for in order to fill in a form field. Been so long in fact that i just automatically assumed it had to be a coding problem on my end rather than something on their end.

I just replaced it with the newer one and was back in business. I didn't see any way to just delete my original post.
