Webbrowser Click Fires Twice
Dec 4, 2009
In VS2005 I am using click on some elements in a webbrowser document to perform certain functions, eg print or open MS Paint but for some reason all the mouse events fire twice. A second click on the same element might be intentional so I can't just bypass code if the ID is the same as last time. There are no other calls of Document_Click anywhere in the project.[code]I supposes I could stick a timer on it and ignore any within 1s say but cheers for any more elegant solutions.

A form has many buttons. One of those buttons contains code to update the TableAdapterManager. One of the many TextBox controls has code in a Validating event handler. There is code to make sure a US phone number is formatted properly.If the user tabs out of the TextBox the Validating code works perfectly and show a message to the user if the phone number is not properly formatted and the focus is place in the offending TextBox.If the user clicks on a button that has code to update the TableAdapterManager the Validating code fires but instead of focus remaining on the offending TextBox, the code in the button Click handler also fires.
I would like to stop the button code from firing.Here is the code for the Validating event of the TextBox:
Private Sub TextBoxPrimaryPhone_Validating(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles TextBoxPrimaryPhone.Validating
' Make sure the phone is formatted correctly.
[code]....
What additional coding to I need to include so focus remains on the TextBox?

I have a grid that displays data from a binding source. I have a method to handle the CellContentDoubleClick which will get the value of the cell and use that to do a new look up. This will generate a new datasource (with different columns) which I then rebind to the grid.
My grid double click works, but when it repaints with the new data, a single click fires the double click. This happens whether or not thre is a single click handler.
The interesting thing is that it is (in my case) a toggle. If I double click, on the repaint, a single click fires the double click code. When it repaints again, I need a double click.
The double click code fires off a messagebox - if I tell it not to continue, then I have to double click to get it to fire again. So it is not dependant on what data is displayed.
When it is in the mode to respond to a single click, I can tab through all the controls and then click on any cell in the grid and it will still fire the double click.
No matter what I try to do (set focus to other controls, refresh the grid, etc.) nothing seems to reset the grid so it works consistently.

I have a tree view with checkboxes. When a user checks an item in the tree, all items below it in the tree should be checked automatically to match the parent. The same is true is a user unchecks an item. That's been reasonably easy to implement using the after check event:-
Private Sub tvwUserGroups_AfterCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles tvwUserGroups.AfterCheck
If Not m_Isloading _

So I've got this context menu working out except that the event behind the actual selection of the menu item seems to fire multiple times. First time I click it, it fires once, then twice, then 3 times. So, in the example I just gave, for 3 clicks it would have fired a total of 6 times (1 + 2 + 3). Why is that?
Below is my code on how I'm creating the menu items. I stripped it down to the relevant pieces; I omitted things like .Tag, .Visible, and .Caption properties. I'm building this using .NET 3.5 and VS 2008.

In java, if you've ever scripted java, there is a class called "Rectangle" in which will click in the specified Rectangle. Well in a WebBrowser, is it possible to click a certain Rectangle? (Only in the webbrowser), or a certain point
So navigate, wait for DocumentLoad, then click in rectangle?

I am trying to automate a web page via the weBrowser and the button that i'm trying to click has no ID only a value. here's the html code for it: "<button class="buttonf" onclick="window.location='staticpage.php?accept=123456' ">Accept</button>"
I can't useGetElementById as the button has no ID. If I do
HtmlElement goButton = this.webBrowser1.Document.All["Accept"];goButton.InvokeMember("click");
My script stops showing a nullreference error highlighting the "goButton.InvokeMember("click");"
[Code]....
My script give me an "Sequence contains no matching element" error at the "HtmlElement submitButton" line and sometimes the page has more than one of these Accept buttons, so I would need to be able to tell the difference between each one as well or at least be able to click on one without the script breaking

I am working at a small VB.NET project which autofill the fields on Yahoo register page. I was wondering if there is a way to click on "Check" button and see if the entered ID is ok or not, something like if the entered ID is ok then proceed further with filling the field, if not, try another ID and press "Check" button again.

how would i click a button on a webbrowser without id ?
html
<input type="submit" value="Go to mail.com Now!" name="BorderBoxAccountInfo:PanelAccountInfo:ButtonAccountInfo" id="id6ae"
The id changes everytime its clicked so we cannot use the id :/ so
WebBrowser4.Document.GetElementById("id132").InvokeMember("click")
That wont work as its id and that changes on every click?

how to click a button in the WebBrowser Control... I've tried stuff like:
WebBrowser1.Document.Forms(0).Item("btnG").Click but this doesn't seem to work.
So how would you go about clicking a button in the webbrowser control in Visual Basic 2010? how would you type "Daniweb" into the google search bar and click the "Google Search" button?

I've managed to fill in the username and password with the necessary details but I can't seem to click the submit button.
This method works on all other sites I've tried, but not this one. The button name is submit (Tryed all from source and looped through the input elements which it can't be found on there).
Might it be on another form or is it somthing to do with JS?
