WebBrowser的内存释放

WebBrowser窗口自动滚动：

this.webBrowser.Document.Window.ScrollTo(0, webBrowser1.Document.Body.ScrollRectangle.Height);

 

WebBrowser的脚本出错信息：

当页面上的脚本出错时，一般情况下会弹出脚本出错提示，如果在用WB写爬虫一类的时候，这类提示可能会导致系统不能工作，解决的发是：

(1)设置属性ScriptErrorsSurpressed = true;

(2)打开IE的设置 "Internet选项" - "高级" - 勾选"禁用脚本调试"

 

WebBrowser的内存释放：

WB的内存开销很大，当连续打开很多网页时这个问题将会非常明显，甚至耗尽内存，解决的方我在MSDN论坛上找到(来源： http://social.msdn.microsoft.com/Forums/en-US/ieextensiondevelopment/thread/88c21427-e765-46e8-833d-6021ef79e0c8/)，具体如下：

 

 

This solution worked for me!! 
Thank you so much mike_t2e!!!!!!!

Is the memory released when you minimize the app ? If so, try this:

-- in class definition 

        [DllImport("KERNEL32.DLL", EntryPoint = "SetProcessWorkingSetSize", SetLastError = true, CallingConvention = CallingConvention.StdCall)]
        internal static extern bool SetProcessWorkingSetSize(IntPtr pProcess, int dwMinimumWorkingSetSize, int dwMaximumWorkingSetSize);

        [DllImport("KERNEL32.DLL", EntryPoint = "GetCurrentProcess", SetLastError = true, CallingConvention = CallingConvention.StdCall)]
        internal static extern IntPtr GetCurrentProcess();

-- code to call when you want to reduce the memory

            IntPtr pHandle = GetCurrentProcess();
            SetProcessWorkingSetSize(pHandle, -1, -1);
