blocks|key|1369879|text|请注意，传递给Zoom函数的因子值假定值100对应于网页的“正常”大小。系数的值越高，意味着你正在“放大”，所以页面看起来更大。系数的值越小，意味着你正在“缩小”，所以页面看起来更小。我发现因子之间的合理增量是10。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1369880|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Note that the factor value that you pass in to the Zoom function assumes that a value of 100 corresponds to the "normal" size of the web page. Higher values of the factor means you're "zooming in", so the page looks larger. Smaller values of the factor means you're "zooming out", so the page looks smaller.
I found that a reasonable increment between factors is 10.

This works for me:

<pre><code>int zoomFactor = 300;
((SHDocVw.WebBrowser)webBrowser1.ActiveXInstance).ExecWB(SHDocVw.OLECMDID.OLECMDID_OPTICAL_ZOOM,
 SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_DONTPROMPTUSER, zoomFactor, IntPtr.Zero);</pre></code>

It seems this can be done only after the document has been loaded.

blocks|key|1370019|text|对于像我一样遇到同样问题的任何人，这里是对Gloupi的答案的修改，它应该可以在更多的国际系统上工作，通过使用数字键盘符号键，加号和减号键位于不同的位置。这也修复了dvorak布局的放大和缩小。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1370020|//+zoom+in
webBrowser1.Focus();
SendKeys.Send("%5E{ADD}");

//+zoom+out
webBrowser1.Focus();
SendKeys.Send("%5E{SUBTRACT}");

//+zoom+reset
webBrowser1.Focus();
SendKeys.Send("%5E0");|code-block|syntax|javascript|1370021|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

For anybody that runs into the same issue as I did, here is a modification to Gloupi's answer that should work on more international systems where the plus and minus keys are in different locations by using the numpad sign keys. This also fixes the zoom in and out on dvorak layouts.

<pre><code>// zoom in
webBrowser1.Focus();
SendKeys.Send("^{ADD}");

// zoom out
webBrowser1.Focus();
SendKeys.Send("^{SUBTRACT}");

// zoom reset
webBrowser1.Focus();
SendKeys.Send("^0");
</code></pre>

In IE7 there's a "zoom" feature built-in (show in the status bar), allowing you to zoom in up to 400%. I'm using the WebBrowser .NET control in a demo/simulation app, and need to zoom in on a web page. Is this at all possible?

(I don't want to simply take a picture of the page and enlarge it, as I need to use the links and buttons on the page).

I'm using .NET 2.0 if it matters.

Zoom in on a web page using WebBrowser .NET control

在IE7中有一个内置的“缩放”功能(显示在状态栏中)，允许你放大高达400%。我在一个演示/模拟应用程序中使用WebBrowser .NET控件，需要放大一个网页。这有可能吗？(我不想简单地为页面拍摄一张图片并放大它，因为我需要使用页面上的链接和按钮)。如果重要的话，我正在使用.NET 2.0。
