基本上我有太多的代码来分离这个例子的最小值,但我已经提供了下面的算法,你可以倾注一下。
当它们再次出现时,它也跟踪浏览器中的标签(仅限IE),因此您需要去除不需要的位。我似乎记得我为IE8修复了这个问题,但不确定是否修复了这个代码,所以如果需要稍微调整一点也不要感到惊讶:)
// Iterate all browsers and record the details
IntPtr hWnd = IntPtr.Zero;
NativeWIN32.EnumChildWindows(hWnd, new NativeWIN32.Win32Callback(BrowserEnumCallback), hWnd);
/// <summary>
/// Called back for each IE browser.
/// </summary>
/// <param name="hWnd"></param>
/// <param name="lParam"></param>
/// <returns></returns>
static bool BrowserEnumCallback(IntPtr hWnd, IntPtr lParam)
{
// Is this app IE?
if (NativeWIN32.GetClassName(hWnd) == "IEFrame")
{
// If this is a new browser, add it
if (!BrowserWindows.ContainsKey(hWnd))
{
// Record the Browser
BrowserWindow browser = new BrowserWindow()
{
hWnd = hWnd
};
// Store the browser in the temp list and temp member
TempCurrentBrowser = browser;
BrowserWindows.Add(hWnd, browser);
}
else
{
// Store the browser in the temp list and temp member
TempCurrentBrowser = BrowserWindows[hWnd];
}
TempCurrentBrowser.WindowText = NativeWIN32.GetWindowText(hWnd);
TempCurrentBrowser.Found = true;
// Now that we know it is a browser, look for tabbed windows and address bar
NativeWIN32.EnumChildWindows(hWnd, new NativeWIN32.Win32Callback(BrowserEnumChildrenCallback), hWnd);
}
return true;
}
/// <summary>
/// Called back for each child window in the browser
/// </summary>
/// <param name="hWnd"></param>
/// <param name="lParam"></param>
/// <returns></returns>
static bool BrowserEnumChildrenCallback(IntPtr hWnd, IntPtr lParam)
{
string classname = NativeWIN32.GetClassName(hWnd);
switch (classname)
{
// This is the main address bar
case "Edit":
{
string url = NativeWIN32.GetWindowText(hWnd);
if (url.StartsWith(@"http://") || url.StartsWith(@"https://") || url.StartsWith("about:"))
{
TempCurrentBrowser.Url = url;
return true;
}
}
break;
case "ComboBoxEx32":
{
string url = NativeWIN32.GetWindowText(hWnd);
if (url.StartsWith(@"http://") || url.StartsWith(@"https://") || url.StartsWith("about:"))
{
TempCurrentBrowser.Url = url;
return true;
}
}
break;
// Record any sub pages still active, by title to avoid revisiting popup
// If this name matches the name of the browser, it is the current window
// If so, record the browser url for reference in that tab window
case "TabWindowClass":
{
string title = NativeWIN32.GetWindowText(hWnd);
BrowserTabWindow tabWindow;
if (!TempCurrentBrowser.TabWindows.ContainsKey(hWnd))
{
// Create a new tabbed window for the current browser
tabWindow = new BrowserTabWindow()
{
hWnd = hWnd
};
TempCurrentBrowser.TabWindows.Add(hWnd, tabWindow);
}
else
{
tabWindow = TempCurrentBrowser.TabWindows[hWnd];
}
tabWindow.WindowText = title;
tabWindow.Found = true;
}
break;
}
return true;
}
如果Microsoft Spy ++可以看到地址控件,那么是可能的。
我没有安装Opera,但Spy ++中的Chrome控件层次结构如下所示:
我在Internet Explorer上做过类似的事情:
Firefox是问题孩子,因为它在内部呈现地址栏,而不是通过Windows控件,但我发现你已经找到了解决方案。
在C#中,您需要对Windows API方法进行非托管调用。正如您可以从单独的C#API代码(下面)中看到的那样,可以稍微涉及一下:
const int WM_GETTEXT = 0xD;
// used for an output LPCTSTR parameter on a method call
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]
public struct STRINGBUFFER
{
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 256)]
public string szText;
}
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool SetForegroundWindow(IntPtr hWnd);
[DllImport("user32.dll", CharSet = CharSet.Auto)]
public static extern IntPtr GetForegroundWindow();
[DllImport("user32.dll", CharSet = CharSet.Auto)]
public static extern IntPtr FindWindowEx(IntPtr parent /*HWND*/,
IntPtr next /*HWND*/,
string sClassName,
IntPtr sWindowTitle);
/// <summary>
///
/// </summary>
/// <param name="hWnd">handle to destination window</param>
/// <param name="msg">message</param>
/// <param name="wParam">first message parameter</param>
/// <param name="lParam"second message parameter></param>
/// <returns></returns>
[DllImport("user32.dll", CharSet = CharSet.Auto)]
public static extern int SendMessage(IntPtr hWnd,
int msg, int wParam, out STRINGBUFFER ClassName);
[DllImport("user32.dll", CharSet = CharSet.Auto)]
public static extern int GetWindowText(IntPtr hWnd, out STRINGBUFFER ClassName, int nMaxCount);
[DllImport("user32.dll", CharSet = CharSet.Auto)]
public static extern int GetClassName(IntPtr hWnd, out STRINGBUFFER ClassName, int nMaxCount);
//[DllImport("user32.dll")]
//[return: MarshalAs(UnmanagedType.Bool)]
//static extern bool EnumChildWindows(IntPtr hwndParent, EnumWindowsProc lpEnumFunc, IntPtr lParam);
public delegate bool Win32Callback(IntPtr hwnd, IntPtr lParam);
[DllImport("user32.Dll")]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool EnumChildWindows(IntPtr parentHandle, Win32Callback callback, IntPtr lParam);
/// <summary>
/// Helper to get window classname
/// </summary>
/// <param name="hWnd"></param>
/// <returns></returns>
static public string GetClassName(IntPtr hWnd)
{
NativeWIN32.STRINGBUFFER sLimitedLengthWindowTitle;
NativeWIN32.GetClassName(hWnd, out sLimitedLengthWindowTitle, 256);
return sLimitedLengthWindowTitle.szText;
}
/// <summary>
/// Helper to get window text
/// </summary>
/// <param name="hWnd"></param>
/// <returns></returns>
static public string GetWindowText(IntPtr hWnd)
{
NativeWIN32.STRINGBUFFER sLimitedLengthWindowTitle;
SendMessage(hWnd, WM_GETTEXT, 256, out sLimitedLengthWindowTitle);
//NativeWIN32.GetWindowText(hWnd, out sLimitedLengthWindowTitle, 256);
return sLimitedLengthWindowTitle.szText;
}
所涉及的算法基本上从桌面上搜索所有窗口,直到找到 Browser 窗口(基于特定的类或窗口属性)。然后,它根据浏览器的类型搜索特定的子元素。当您最终到达地址控件时,您可以从控件中提取地址。希望我的助手类代码能加速你的开发。

除非记录浏览器本身提供该信息,否则我认为没有可靠的方法。
话虽如此,我很确定至少Chrome会将磁盘上的历史信息存储在磁盘上,所以最好的办法是找出它的位置,格式以及如何阅读。
答案 3 :(得分:0)
IE11,Chrome,Firefox,Opera,Safari都有接口来获取URL甚至是DOM,或者至少是文档/ HTML缓冲区。 FF实际上有一个带导出的DLL来为你做,我忘了如何在其他人之下可靠地做到这一点,但我知道它已经完成了。

解决此问题的另一种方法可能是使用UI Automation框架。
此示例读取Chrome的当前网址:
var app = AutomationElement.FromHandle(new IntPtr(chrome_hwnd));
var propFindText = new PropertyCondition(AutomationElement.NameProperty, "Address and search bar");
var textbox = app.FindFirst(TreeScope.Descendants, propFindText);
Debug.WriteLine( textbox.GetCurrentPropertyValue(ValuePattern.ValueProperty).ToString());

从IE中找到开放的网址
从COM选项卡添加引用“Microsoft Internet Controls”,然后:
using SHDocVw;
我的完整指令列表如下所示:
using System;
using System.Collections.Generic;
using System.IO;
using System.Windows.Forms;
using SHDocVw;
现在要从IE中找到标签网址,请执行以下操作:
Dictionary<int, string> ieUrlsDictionary = new Dictionary<int, string>();
ShellWindows ieShellWindows = new SHDocVw.ShellWindows();
string sProcessType;
int i = 0;
foreach (InternetExplorer ieTab in ieShellWindows)
{
sProcessType = Path.GetFileNameWithoutExtension(ieTab.FullName).ToLower();
if (sProcessType.Equals("iexplore") && !ieTab.LocationURL.Contains("about:Tabs"))
{
ieUrlsDictionary[i] = ieTab.LocationURL;
i++;
}
}
//show list of url´s
for (int j = 0; j < ieUrlsDictionary.Count; j++)
{
Console.WriteLine(ieUrlsDictionary[j]);
}

我通常使用这样的东西:
//打开浏览器后: browserHandle = GetForegroundWindow();
SetFocus(browserHandle);
// send ctrl-d to get in address bar
SendKeys.SendWait("%{d}");
// send ctrl- to copy
SendKeys.SendWait("%{c}");
// then paste it where you want it
您需要DLL导入:
[DllImport("user32.dll")]
private static extern IntPtr GetForegroundWindow();
