Clicking A Button In WebBrowser?
Sep 11, 2010
I figured this would be simple, but I can't seem to figure it out. I can't make WebBrowser click the button I want without any errors involved.
[Code]...
I'm trying to make the program click on the "Join" button on that website, and with the code above it does click on the join button, but it seems to ignore any type of javascript involved with the button, therefore giving some type of website error. Is there a better way to click that button so it won't produce any website errors?

So normally for clicking a button you would use:
WebBrowser1.Document.GetElementById("id").InvokeMember("Click")

To fill in data i use
WebBrowser1.Document.GetElementById("visitormail").SetAttribute("Value", "test@yahoo.com")
and for
HTML
<input type="submit" value="Send Mail" />
i cant figure out how to make the code to click the submit button?

How do i click a button, preform some if statements (if it matches, exit...) else keep looping (clicking the button)...How do i do this within the web browser controlormal loop won't work because the web browser executes the statement multiple times before completing and i can't figure out how to make it loop until a condition is met without freezing the program.

<tr>
<td align="right"></td>
<td align="left">
<input name="userId" value="8194364" type="hidden">
<input name="action" value="saveChanges" type="hidden">
<input class="submitImage" src="/theme/default/buttonSaveChanges.gif" type="image" align="top"><input class="submitButton" value="Save Changes" type="submit"></td>
</tr>
[Code]...
Again the code clicks the button, but doesn't save the information so I figured it has something to do with the hidden value. I've never seen this problem before so I don't know where to go from here.

When the user clicks the Exit button it closes the forms and if there was an open file it asks the user is they would like to save. But after the application closes there is still memory being held in Processes by the application. However, when pressing the [X] in the top of the form the application closes again but in this instance it is not held in Processes. How do I write the close for Exit to take into account how the [X] works and close the application cleanly?
Friend Sub CloseAllForms()
CloseHelpForm(True)
CloseDiagForm()[code].....

I believe there wont be any diff if user clicks the button on the form and the click event is fired OR if we call the button click event / function in the code. Because in one my project, this does make diff. If I click the button on the form, the App works great but same button if I click it thru the form code, the whole process crashes. This happens in Vista / VB.net.

For the past couple weeks I've been tormented by this problem: I am trying to make a program that will go to a specific web site and add things to my cart on that page. I can get the program to go to the page, log into my account, and get to the right product. But, I can't figure out how to click on the ADD TO CART image.
Also, each product page has the main product, with an ADD TO CART image, and at other places on the screen there are other products shown, each with its own ADD TO CART image.I have been examining the source for the pages and here are a couple examples:
[Code]...
How can I click on one of those addToCart.gif images? It looks like they do not have names or IDs for me to refer to them with?

I have a question regarding clicking a button on a web page through the web browser control in VB .Net Express Edition. I have figured out quite a few tricks and stuff with the web browser control but I can't figure out how to automatically click a button. I know I can invoke the 1st instance of a "submit" type button but I want to click the 3rd instance (or chose which ever one I want). Unfortunately the button declarations in the HTML don't have ID or NAME tags to make it easy to pick them. How would I go about extracting all the buttons on a form in an array form, so I could invoke a certain member of that array and click a button of my choosing. Is this possible?

Everything works fine except the login, it gives me an "Object reference not set to an instance of an object" error.

Im currently working on a project which included a webbrowser navigating to a website. Whenever it arrives there it disables me to double click on the Media Player inside the website to go full screen. Although I know this is possible as Ive seen that the webbrowser can disable clicking on Firefox. My question: is it possible to enable the standard webbrowser in Vb.Net to allow me clicking even if the website doesnt.

What I'm trying to do is click an html link inside of a html table via code in vb.net using a web-browser control. The link I want to click can be anywhere in the first column of the table so I need to cross reference with another column in the table to make sure I have the re way I'm going about this is to loop through the html elements till I find the table I want (multiple tables on the page) then dump that table to an array. Then loop through the page again get to the table I want and then start comparing the link and another column in the now array. I need to check to make sure that the url of the link contains a work and that another column in the table contains a specific or lower numerical value. Basically where I'm stuck is while dealing with the html element "Table" wanting to identify and interact with another html element inside it.
'Flag to say dump to array
Dim RecordFiles As Boolean = False
'The last two headers in the table are blank so need to skip them
Dim FirstBlank As Boolean = False
Dim SecondBlank As Boolean = False
[Code] .....

I have a message box pop up if a practice doesnt exist in my application. However, the user MUST select 'OK' on the message box to accept the message. When you use enter button on the keyboard it doesnt work.Is there anyway I can allow enter button also to be used rather than ONLY clicking 'OK' button.
If saved_prac = "" Then
MsgBox("This Practice doesn't exist", MsgBoxStyle.Information, "GCPM")
End If

I'm brand spanking new and trying to learn VB.net on my own but am doing a horrible job. It seems I can follow basic tutorial instructions and do them correctly but not learn how to do things on my own.
Anyway, I'm trying to do simple stuff first like have a textbox and a button that I click that adds 1 to the value in the textbox and makes the textbox output that value but I can't get it to work for the life of me. I know it's probably something really easy but yeah, I just can't figure it out after scouring the net now for about 45 minutes.[code]...
