Text size in WebBrowser control

[Branislav Vidovic]

Hy guys! I have a question about text size in WebBrowser control in MS Visual C# 2005 Express Edition. You know when you view web pages in a browser you can alter the overal text size from the contex menu. For example when I open MSDN help in C#, from the context menu i can choose the text size. I actually found out that this operation afects also my webbrowser control. So if i choose "Larger" text size when i am viewing MSDN, my webbrowser control will also change it's text size. My question is: How can I control the text size in my webbrowser control? Is there a property or some way to do it? Thank you for your time. Cheers!

Just a thought, I know you access to the DOM so you might be able to do this if you set the style on the body of the doument.

If at first you don't succeed ... post it on The Code Project and Pray.

Yes, the WebBrowser Control uses the settings you defined while using Internet Explorer. It also shares a lot of code with IE. For your own web pages, you can set all style attributes within your pages themselves, using either HTML, XHTML or better yet CSS. For exisiting pages, I don't know if and how you can programmatically alter the IE settings (and I would not like an app that modifies how IE works without me asking it to do so). Well, actually I don't use IE that much, there are even better browsers around :laugh:

The quality and detail of your question reflects on the effectiveness of the help you are likely to get. Show formatted code inside PRE tags, and give clear symptoms when describing a problem.

I did a little looking for you and you can call WebBrowser.Document.InvokeScript to execute some script on the document. So you could do something like this

webBrowser1.Document.InvokeScript("body.style.style.fontSize = '10pt';");

I'm not sure if you can directly execute javascript like that you might have to use a function. You could always add your function to a page by appending the script to WebBrowser.Document.InnerHTML InvokeScript(string) - MSDN[^] OR if you want to create a function in your page to do the sizing and pass it parameters InvokeScript(string, object)[^]

If at first you don't succeed ... post it on The Code Project and Pray.
