I was offered this interesting scenario by a visitor of my site and have been trying a few approaches, but not seeming to get it quite right. I have a Form with a WebBrowser control (or an AxWebBrowser if that works too) and on the page loaded in the browser, is a link that uses javascript to open a new popup window.This popup window I am unable to take "ownership" of and it launches in a new instance of the user's default browser (IE for this scenario). I need to then interact with that javascript popup window which now is not part of my application. If I needed to set a value of an input box on that form, how would I accomplish that if I can't "interact" with the form?
I have a Javascript function in the js file (test.js) and I need to call her in visual basic 2010 enter her input parameter and load response javascript functions in visual basic.
Part of my project is to retrieve a string variable from an external source (google docs) and parse it. This string represents width and height. I have no problem retrieving, I just need to parse it in to two strings. The string has 4 variations.
Here are examples: 3"x4" 3"hx4"w 3hx4w 3x4
The width is always the first number and the height is always the second. Sometimes, the width and height have decimal points. Any way to parse this into two strings of the numeric values only?
The main problem is I couldn't display the result when I retrieve data from database.
1. On Picture 1 above, for the Dg_Details, I set the Columns in two type, textbox and checkbox. But, for the datagridview1, I didn't set anything.So, when I bind data from database to Dg_Details and datagridview1, the datagridview1 display the data from database, but the Dg_Details doesn't display the data. Below is the code I written in my form :
I am trying to create a program that is able to submit post data for the page [URL] where it submits the request fields and then the resulting page is receiving in a string.
I am having trouble extracting links from a web page and it involves javascript running on a website that contains the url links i need. I have encountered this issue before and was able to resolve it by getting the javascript file and then parsing it for the links. However this time I am unable to find the javascript that contains the links.To better clarify here is the source code segment from the web page:
I have a HTML checkbox which will perform a simple validation on another textbox, so the textbox will only be enabled if the checkbox is checked, but I also want to access this checkbox control in code behind to check and uncheck it. I don't think I can use the runat="server" because on the onClick event which will cause ('<%=uitxtVouTypeRedeemValue.ClientID%>') to be output as plain text.
i have a script that reads an xml file then produces some document.write javascript lines and sends them to request . I'm getting a weird character (only shows in internet explorer, not firefox). I can't seem to track it down. Here's a URL of the script being used (has weird chars in IE)The source of the javascript tag is where the .net script is
I'm loading HTML into the web browser control, and adding a bit of javascript that hightlights a section of html when the user clicks on the area, by changing the classname. If you know the FireBug addin for Firefox, it's very similar to that. But what I need to do after this, is take the HTML source, and find where they clicked. But when I get the DocumentText of the webbrowser control, it's the original source. Not the source with the added class name.Is there a way to get the source code with the javascript generated html?
I have a webpage I would like to parse but not too sure how to capture the links activated by clicking on links. I have take suggestions about using regex to capture the onclick statements but that does not seem to help since it does not capture anything. Here is an example of what the html contains:
Now if I capture 'SelGenre' and try and normalize that with the webpages root etc it does not work. Clicking on the link will display other links that I need to capture.I thought it may contain some javascript file but it did not even after trying to use firebug.
I have dynamic html table and every cell have one checkbox. I want to get the selected checkbox if the user select from multiple checkbox from different row.
function GetAllChecked() { var chkedshid = new Array(); var rows = new Array();
[Code]....
why why this function return just last selected checkbox for last row in loop? i need the all selected checkbox for all rows!
how do I disable browsing to a http link from a Html editor. I have a vb.net web form with a html editor, when I add a hyperlink to the html editor, for example my application website for instance[URL]...When I run and click the link I can browse my application from inside the Html Editor which is so weird.It should open the link in a new window. How do I stop this from happening.This is an Intranet application. And the component for Html Editor is of TMS.
Or is there any Javascript code available where I can deactivate the link from an HtmlEditor, i mean when i add any hyperlink it should be not be activated , or no should be able to browse it from inside the HtmlEditor ?
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:
Need to connect & retrieve from SQL DB in aspx page using vbscript server side. I have an html page which I want to edit by adding information from a SQL database & display results on and in the html page (code below). Initially thought of using server side javascript but unsuccessful, can this be done using vbscript?
I would like to ask a question with SchDocVW Internet explorer control.I added the reference "Microsoft Internet Controls" forum. [code]Could anyone give a known-good working example of how SHDocVW can be used to retrieve HTML contents reliably using VB?
I have to insert text box at button.click event. for this I've been using this code implement it, in ASPX.VB file. below code refecting attached screen shot, which displaying the textbox beside to the delete button. Issue: Example: If we insert any simple text box in ASPX page, then we can take that textbox id and we can play with that in aspx.vb file . in the same way I would like to play with the below code by having the textbox Id. How? How I need to take this text boxId(id = ""txtExperimentalStressdays"") and save the user entered data into database.
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]
In VB.NET 2005, what is the best way to retrieve and parse HTML data from a URL, a bit like a search engine crawler?I am building an app, where I need to parse a website, and collate data from it (the website uses some tags that I could pull out to get the appropriate bits of data). I want to be able to do this in a thread, and just update a DB with the data, and give the client app a status update of the progress.
I'm using the following code to retrieve a URL and then parse the HTML from the page:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStart.Click Dim Temp As String, searchstr As String
[Code]....
I think my problem is that I don't exactly understand how I am supposed to start and end the parsing. I know that in my above code, the "meta" tag is the start and the chr(34), double quotes, is the ending.
When I modify my code, I have price line, which in th html ends with another character, the ">" sign. In the first code, the "content" tag doesn't end with another character, it just continues the line, which is easy and it works.
Here is my problem: I need to store HTML in a MySQL database. Afterwards, I need to be able to retrieve the HTML and have it be valid HTML that a browser can render.
How can I store HTML in a MySQL database using .Net? How do I retrieve it afterwards? As this is the design phase, I can create the database any way that is needed.
I need to create a VB.net app that automatically reads a html table. It should connect to a web address (eg "[URL]") and read it. I'll be happy if I could just get the full HTML. I was able to use this code to get the HTML of a regular website:
Dim strReply As String = "NULL" Dim objHttpRequest As HttpWebRequest Dim objHttpResponse As HttpWebResponse objHttpRequest = HttpWebRequest.Create("[URL]") objHttpResponse = objHttpRequest.GetResponse Dim objStrmReader As New StreamReader(objHttpResponse.GetResponseStream) strReply = objStrmReader.ReadToEnd()
This code sample will give me the HTML for the website [URL]. However it will not work with the website I want (eg "[URL]"), because when you access it via regular browser it will popup a browser dialog asking for credentials (user / pass). So when I run the code above for it, I'll get the exception: The remote server returned an error: (407) Proxy Authentication Required.
How do I set this up to use the credentials, before retrieving the HTML? This is actually my first web-related app.
