I am building a WP7 app (RTM version of the dev tools, not the Mango Beta dev tools) and am using the silverlight linklabel control (http://silverlightlinklabel.codeplex.com/).
This control should find all urls in the text given to it, and turn them into hyperlinks, but i am finding that it finds the urls and inserts the hyperlinks, but no text is shown, even though the text property is set on the hyperlink object.
While i have been playing around, i have found its possible to click the hyperlink and take you into mobile IE to visit the url, but there is no visible text.
I am using the latest version of the control, i only made one change so it works correctly on WP7 which is to do with the creation of relative Uri's
So what i am asking is, has anyone else tried this and found a solution? Or is there a better way of doing it?
Thanks in advance for your help

I made an chat application that uses listBox and each time someone sends a new message the text is displayed in the list box, I want to make so if someone sends either message starting with http or https to be clickable and open the link in an default browser. I use Visual Studio 2019 Enterprise. I tried searching the web but didn't find what I was looking for and I have no idea how to do it myself. Any help highly appreciated.
EDIT: I want to make links clickable that are displayed in an listBox screenshot its an win forms application
1. Get the selected item as string - listBox1.SelectedItem.ToString(); https://stackoverflow.com/a/18065641/13028588
2. Find word that has http:// or https:// C# - Maybe this can help https://learn.microsoft.com/en-us/dotnet/csharp/how-to/search-strings
https://learn.microsoft.com/en-us/dotnet/api/system.string.contains?view=net-5.0
Find text in string with C#
3. After you get the link as string you can use this -System.Diagnostics.Process.Start("https://thelink.com"); - How to open in default browser in C#
This is just to point you in the right direction hopefully.
I need to display PDF preview in WPF control, programmatically search for text in it, highlight found text and be able to copy text. Sounds simple, but I am struggling with different approaches for a week already.
Here what I have considered:
Find PDF controls for WPF
Most of them just render PDF as images or cost too much. Royalty or subscription fee is not an option.
The only suitable control that I found is:
http://www.syncfusion.com/products/wpf/pdf-viewer
I was even able to do searches programmatically with reflection hacks, but it renders text too blurry (Syncfusion promise to fix this soon) and load pages with a noticeable lag during scrolling.
Using AcroPDFlib as an ActiveX component
I was not able to make it work with the latest Adobe reader on Windows 10 64-bit. But I don't see methods for search anyway, so I dropped this. Also, it seems that it is not free for commercial use:
AcroPDFlib, AxAcroPDFLib commercial use
Load PDF in WebBrowser control
It works and even allow searches, but it can search only for single words which make this search useless. If I search for "big apple" it highlights all big and apple and also open this search panel that cover the document.
Send CTRL+F and text to the browser control to trigger search
I have tried to use this library
http://inputsimulator.codeplex.com/
But PDF in browser control seems to ignore keystrokes from there or maybe I am doing something wrong. Still considering this option.
Use pdf.js in browser control
IE7-based control from WPF won't support that, so I need another browser control. And it seems that I also need to start nodejs to make it work. Seems like a too much overhead for this task. And also it is not clear does PDF.js supports search for a phrase or not.
But I am still not discarding this option. Does anyone were able to make it work inside WPF?
Any suggestions?
I am coding a Windows Forms Application in C#, and one of the requirements is to display some html code in a control, with the correct colors that correspond to the relevant tags.
E.g. When right clicking on a webpage in Google Chrome, then selecting View Page Source, a form is shown with all the html, correctly formatted, with tag colors and each line of code's line number.
Is there a free, reliable control that can do this? Is there an inbuilt Microsoft control that does this?
As I am new to this area of coding, can someone please provide me with some useful names, and some resource links if possible? I am not sure of the correct name for a control that does this, and as such, my Google searches have not come up with what I am looking for.
Also, the control needs to be trustworthy.
Thanks
You can try ScintillaNET control. It's open source and has HTML syntax highlighting as well as many other features.
I am attempting to create a 'find on page' search option for a wp7 webbrowser control named 'TheBrowser' (using the standard webbrowser control in Visual Studio). I have done a lot of research but have not found much in the way of an example or sample where this was implemented. Essentially I will just be activating the search on a click event, from a textbox where the user may type in a word to search in the current webpage. I would also like to highlight the matched words as seen when doing a find on page search on a desktop browser.
I believe that to create this 'find on page' option I should use javascript to search through the lines of text, and then somehow highlight matched words. I have already implemented forward, back, and refresh buttons using TheBrowser.InvokeScript, but I do not know how to format for searching through the entire webpage (I have never done anything like this before). Any advice or assistance would be greatly appreciated, including code samples as I am completely new to this subject! Thanks in advance for your help and hard work!
Try jquery, this should do the trick: http://hugoware.net/blog/more-jquery-magic-search-highlighting You'll just need to inject the jquery script into the page.
I'm in a trouble trying to fix some problem.. I have a program with Webbrowser control inside it.
It automates crawling process from some website. The problem is that I cannot fix webbrowser after recent website changes.
They have changed page navigation on website. And when I do actions MANUALLY in webbrowser (in my app) it doesn't go to the next/previous page on website. It does nothing... Whereas it works properly in IE 7/8/9 (only scripting errors thrown this time).
So does it mean that Webbrowser is not fully similar to IE??
I'm sorry for not showing source codes here, I think it wouldn't help here. Which way should I go to troubleshoot it? Why page navigation is not working in Webbrowser control?
I tried to simply put Webbrowser on a Window Form in new project and tried to navigate page 2/3/../10 in the website catalog, but it simply changes page number and doesn't navigate to it...
EDIT: Website doesn't work propely even if I do actions manually in webbrowser using mouse clicks.. but works in IE.
EDIT2: I might be not clear in my question. The problem is that I cannot use website even Manually with mouseclicks via my Webbrowser control in app. It changes page number after I click on it, but it doesn't navigate to that page. It stays silent. I'm sure that AllowNavigation property is true. It worked just yesterday and stopped after website changes today... Please tell me which way should I go to troubleshoot it.. I thought that Webbrowser control acts the same way as Internet Explorer.. Any help from you highly appreciated! Thanks
EDIT3: Strange thing... i just loaded Extended Webbrowser and navigated to that website. Page navigation panel doesn't work there also.. Is it a bug on their side or some type of guard from crawlers? What do you think?

I'm sure this isn't the answer your want but using the webbrowser control to scrape websites is very painful to maintain.
Instead use the HttpWebRequest and HttpWebRepsonse objects to recreate the calls to the webserver.
You can use Fiddler (http://www.fiddler2.com/fiddler2) and your browser to record your web sessions and recreate them in code.
You can setup your webbrowser control to disable a number of features including navigation.
I.e. to disable nav in the C# WebBrowser control:
webBrowser1.AllowNavigation = false;
I'd double check that you're not doing anything like this.
I had the same issue with a certain web site that recently changed its format. It has to do with the version of IE used by the control.
Simply force the IE version used to the latest (in my case 9). Setting the appropriate registry item to 9999 for my application worked; see: Webbrowser control behaving different than IE
