I'm experimenting with the CefSharp browser for the first time with a WinForm (VB.NET) for a simple browser app I'm working on. There's only one thing that has been bothering me though...
In the past, I have used the stock VB/VS Browser control, and it has worked fine except the fact you have to mess with Emulation modes in the registry to get it to emulate as IE11. The VB/VS Browser control had a DocumentCompleted event that would run an action once the document/webpage had loaded. Namely, I have used this event to set the text of a TextBox to the browser's current URL.
However, I can't seem to find the equivalent (if there even is one) with CefSharp. Does anyone know how to do this with CefSharp?
Any help is appreciated

I'm looking for some input on how feasible it would be to create a Chrome extension that, when activated via toolbar button, adds context menu commands that call procedures (or methods of a class) written in VB.net.
That's pretty much it. At this point, i'd be thrilled to see context menu items that simply display message boxes built in VB.net.
I'm starting with Chrome, but would anticipate replicating similar functionality in other browsers, starting with Edge or IE, then Firefox and possibly Safari. If it's easier to start with another widely used browser besides Chrome, i'd be fine with that.
I've done the obvious google searches, and I can't seem to find an easy-ish place to start. Any ideas?
--edit, just an additional note, the VB.net procedures would be contained in a dll, exe, or other container installed on the client side machine. I'm not trying to execute server side code
Does anyone happen to know why the pagingTextBox doesn't work when using the dgrid pagination? It works fine in FireFox and Chrome but when hitting the enter key in the textbox in IE, it does nothing. I'm using IE 10, but also tried with IE 8. I need this functionality in all 3 browsers. Thanks.
The only event that the paging textbox listens for is change. Apparently, pressing enter registers this event on Chrome and Firefox but not IE. I'm not sure what the reasoning is behind that.
This seems like a legitimate issue to report on dgrid's GitHub issues page though. It shouldn't take too much effort to fix, even if it means listening for 2 types of events.
I've passed many hours searching the web for a solution to something which seems obvious, but without results.
I need to automate a task in a Flash application running on my intranet.
I can't change the Flash application nor do I have access to the source code.
it's not a Flash movie but an application.
I can't download the swf.
I'm using a WebBrowser in a form. The Flash app is displaying without issues.
So far, I have been able to automate the task (clicking on some buttons, then inputting text and finally saving the results on a server). It works but it's not clean at all because I use hard-coded timers to wait a given action is done and then I click on very specific point at given coordinates in the application.
What I would like to do:
Avoid hard-coded timers. the Flash application takes some time to display all elements on the window (from 20 to 60+ sec). I would like to be able to detect when all elements are loaded. I tried to retrieve the text of the windows handle, but while I can retrieve the Flash hwnd, I can't retrieve the content (through messages).
In brief, instead of waiting 60sec (and not being 100% sure it's enough), if the last element to load in the Flash app has "ABC" written in it, I would like to detect it's displayed so that I can continue the sequence (click on the next button).
I'm using VB.net. Any hints to achieve that would be appreciated.
Lol. I am trying to do the same thing but with no results. You can try to see if there are POST/GET codes that can help you if the application has an online nature. Other than that you can only simulate clicks, because flash can't be easily interacted with. This is why most of the things are going to swap with HTML5 now.
Several of my vendor's require me to place orders thru their websites. I have automated the process by clicking on a button in my order processing program. My program will open the default browser (now IE 9 after my previous computer died), navigate to the vendor's website order page, fill out the information fields, and then click the form submit button.
this.oIE.Document.all.ctl00_MainContent_Login1_LoginButton.click()
or
this.oIE.Document.getElementById("ctl00_MainContent_Login1_LoginButton").click()
The problem appears to occur only when the button has an "onclick" value.
In IE8, the click() event executes the onclick code. In IE9, the click event returns a generic object. It does not fire the onclick code.
I have tried x.FireEvent("click"), but this returns an object as well. It appears that IE9 DOM onclick values cannot be executed by external programs.
My program works fine on IE8 (I use Chrome, IE, FireFox with different settings and logins, so changing the default browser is not really an option. Also, some of my vendors demand that I use IE as their sites are broken on the other browsers.)
Any advice on a permanent fix for this would be appreciated.
I could have written your question verbatim, and have been fighting this for as long as you have.
Stupid, stupid problem: The click() function now requires a parameter: click(1)
w = this.oIE.Document
z = w.getElementById("btn-header-input-signin")
z.click(1)
Haven't thoroughly tested this, but it works on the US Postal Service login page.
The function that the button click calls will presumably have the same name on each browser. Can you call that function instead?
Simulating the button click seems an unnecessary step. Also, have you tried jQuery? Libraries like that try to smooth away browser differences.
If I use IE I can visit the website I want and click the 'Next' button and life is good. If I open that same website using the webBrowser control and click the 'Next button I get a javascript error message.
I'm not doing anything in the code to manipulate the website. My goal, eventually, is to have some level of automation; but at this point, I get the javascript error and a pop-up and it screws everything else.
I can hide the JS error from popping up; by setting 'WebBrowser1.ScriptErrorsSuppressed = True' but the page isn't working because of the error.
The client script might be assuming a full browser is present and trying to access part of the browser outside the Document Object Model (DOM) of the page. For example, maybe the client script is trying to display something on the browser's status bar, or trying to modify a toolbar which isn't available in the WebBrowserControl. There could be numerous similar reasons.
If you do not have write-access to the web page in question to try fixing it, then play with WebBrowser Control properties such as ScriptErrorsSuppressed and ObjectForScripting
Try setting WebBrowser1 Silent property to true.
Actually, you are receiving this problem because when you run your site in IE8 or IE9 on your normal internet explorer desktop app, you are getting either IE8 or IE( rendering, depending on which you have installed. However, with the webbrowser control, unless you take the effort to change soem settings in the registry, the default rendering engine used by the webbrowser control is IE7 (if u have 7, 8 or 9 installed) and IE4 (if you have 4, 5 or 6 installed).
This is why you are having the problem, if you want help changing the rendering engine version for your webbrowser control, do a google search as there are many examples on SO, and i have provided this answer in some of my previous posts on this tag/topic. feel free to search or ask me.
Let me know how you go.
