Execute Click - Some Select - Input Text In HTML Page - Using WEBBrowser Control (VS2005)
Dec 13, 2005
I use new WEBBrowser control (VS2005) in my program (WinForm) for open web site. (VB2005)After using method "navigate", in my webbrowser control I have HTML page from some website.This HTML page has some input button with events or input text control or other interactive control on it. I can click with mouse on that buttons or input text from keyboard or select value from combo box to send this page back. question:How I can execute this from my program code, using property and methods WebBrowser control?
I have a form with a Tab Control that has 18 pages. When I click on a tab it opens the page and select a textbox on that page (txtTextbox1. Select() ). This works for the first 8 pages but not for the remaining 10 pages. Although on these pages I can mouse click on the textbox, enter info, save then click my Add button that clears the textboxes and has the code (txtTextbox1. Select() ). The textbox is selected just fine. The code for all my pages is the same except for the tab name and the control names. The tab key will move the selection to the next textbox in order on all pages and the Enter key is coded to do the same. The first 8 pages have a total of 256 labels, buttons, list boxes, textboxes and checkboxes on them.
I am using a Webbrowser control to access the elements in an HTML page which contains a JavaScript link which when clicked, adds extra content to the page. This works fine in IE 7 and Firefox.I then want to access this extra content in my program. Having found the HTML element containing the link, I tried element.InvokeMember("click"). I have used this successfully with a submit-type link to login to the web site, but cannot get it to work with the JavaScript link. I also tried setting the focus to the link element and using SendKeys to send the ENTER key, but all to no avail. Nothing seems to happen. I don't see the extra content produced by the JavaScript, nor do I get an error.Here is an extract from the HTML, showing the relevant (I hope) code:
My VB.NET code is supposed to execute third party Javascript code in an attempt to fill in and submit a form. This process consists of five steps, and I have been able to submit the form when all the steps are kept separate (i.e. behind 5 separate consecutive button clicks). Now, what I'd like to have is one button to handle all the five steps.
The problem is that the form originally only appears after calling "webbrowser.Navigate" command, which apparently modifies the page's HTML code. I seem to be unable to detect when Javascript has finished loading the new HTML in order to fill and submit the form. I have tried a timer control to wait for a certain HTML element ID to appear, but in vain. [URL]
I wrote a VB.Net application that displays HTML help files according to user's search results.A user types some keywords and receives a list of HTML help files containing these keywords.When a list item is selected the HTML file is displayed in WebBrowser control.The problem is that I cannot mark the keywords in the displayed HTML file. I need to highlight them like in a standard Help. I tried many options and nothing works.If I change HTML element style manually (background color for a specific string) all pictures attached to this page are not displayed. After "Refresh" operation the pictures are displayed but the text selection is not enabled.I hope there is a standard function for this operation but I cannot find it.
As it doesn't seem possible to make a new reply to a vBulletin thread, I'm trying something different.A link to a New Reply page is like this http:[url]....I want to fill in the textbox, just as I'm typing now but with a report.I know that
name="message" id="vB_Editor_001_textarea"
So I can do this
If currentElement.Name = "message" Then If currentElement.Id = "vB_Editor_001_textarea" Then End If[code]......
Tried to look for a solution for this problem everywhere and can't seem to find it?I have found solutions related to sub-classing the document, but this method results in a Null Exception as there is no document.

So I'm not trying to edit the value of the textbox. I really don't know what to do here. This is the part of the HTML that I want to input text into: [Code]
I have a Webbrowser control on my Windows Form that loads a local page using the DocumentStream property. The page contains an input element of type text. When rendered, users are able to type anything they wish however they are unable to use keys like "Delete" or typical Cut & Paste functions. If it were not for the fact that you can type data and Basckspace to delete the character one at a time. If I load the same page in Internet Explorer, the input box functions correctly.
I am using webbrowser control in my windows application(VS2003). Below is the code.
Sub LoadHtml(ByRef MyWebBrowser As AxSHDocVw.AxWebBrowser, ByVal sFileName As String) 'MyWebBrowser is webbrowser control added at design time on form and sFileName is .txt file with full path Dim sImgDir As String
I'm working on a pretty simple project, just a WebBrowser app which is tailored for Webmail. I'm working on an OWA portion, and OWA normally doesn't allow the textfields on the Login page to be auto-filled. Is there a way I can force this? Search through the OWA login page code, find the fields, then fill in the fields with preset/saved data?
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
Here is the code snippet that performs this task. It's finds the button, but clicking doesn't work:
htmlDoc = .Document htmlColl = htmlDoc.getElementsByTagName("Input") For Each htmlInput In htmlColl If htmlInput.type = "submit" Then
[code]....
This works nearly every time, but not this time.I've also tried searching for the TagName "Button" and clicking that based on the innertext value of Leave Feedback, but that doesn't work either. I've also tried playing with onclick with something like this:
For Each htmlInput In htmlColl If htmlInput.type = "submit" Then If htmlInput.innerText = "Leave Feedback" Then
I'm creating a program that ought to automatically populate a form on a web site with information, and then submit that form. I've done this kind of thing a lot before, but this time I'm running into an interesting problem -- the "input type=file" element.
With the "input type=file" element, a filename box is automatically created along with a Browse button. Clicking the filename box opens the file browser -- you can't type in the filename box manually.
For my program, however, I want to manually set the value of this filename box. Usually, I would just get the element from the page, then call: element.SetAttribute("value",myNewValue). However, with the "input type=file" element, that hasn't worked, presumably because the user cannot normally manually edit the value of the box (though I could be wrong about that being why).[code]...
I've asked this elsewhere once, and one reply was about how I shouldn't be attempting to write a server that will accomplish this anyway -- so let me make sure it's perfectly clear, I'm just writing a client program that ought to mimic what I would be doing anyway. Its purpose is that there's a particular site that I submit things to whose interface only supports one submission at a time, and I have several hundred things I need to submit.
im trying to find a way of resizing a html document to fit inside my browser correctly.
I would like the width of the page to be the same width of the browser. I can scroll down for the rest. I have no idea on how to do this. Ive found some bits and pieces on the net but nothing is working for me.

I have some update panels on my page that do some asyncpostbacks to keep some dropdownlists correctly populated. My problem is that on my page i have an HTML input that is handling some file uploads. With the AJAX on the page with asyncpostbacks, and while i step through my code behind, the files arent being uploaded. Using a postbacktrigger (non-async) is not possible because of my layout.
When I put a breakpoint in at the declaration of service and then check the value of "files", the count is 0. I am expecting it to be 2 when i have one file uploaded.
In the process of upgrading one of our applications, it was decided that the users needed an image viewer. We already have a browser based application that does a great job at that task. Since a lot of time and effort was put into the browser based code, I really want to use our browser based viewer rather than write new code to do the same.So, I've added a WebBrowser control to a form and figured I will call our Java applet from there and not re-invent the wheel.
what I'm trying to do is setup my browser so that when I click an input field like a username, password, etc I would have a screen pop up where I can assign the "id" or "name" of the tag to a variable. Here is a screenshot of what I am trying to do. screenshot.jpg I am able to create those pop up boxes using a custom Content Menu Strip. Here is the code I have behind the context tab
I'm building a project with VS 2010, a part of this is an automated tax submit through webbrowser control.Although i manage to make it work with 12 different pages i have a problem with one particular page that must be scripted or something (don't know much about web development).
It read some data from a database and put the result into a word document. In this document is a blanc table with a bookmark to indicate the start position.In debugmode this works fine and after distributing thsi is still working fine.A user called me to say that the word document was a complete mess. I ran the application in production mode and yes it is a complete mess. Because the bookmark is not found, the data will be enterd into the wrong column.When i return to debug mode, the apllication is still correct and the result on the word document is good. Behalf of this, there are users who don't have this problem at all.
I have a vb app with a webbrowser, and I am trying to search a page with about 1,000 links to click on the right one. Hereare some links from the page source:
HTML <tr> <td align="center"><input type="checkbox" name="checkedfund" value="9950::Custom"></td> <td>ING LifeStyle Moderate Growth Portfolio - Service Class</td>[code].....
I want to be able to find and click on a link in the page based on its name, like "ING LifeStyle Moderate Growth Portfolio - Service Class" for the first one. Also, I want the second link in each block, with the onClick=notesWindow function. How can I do this?
