c＃如何使用user32 dll处理特定窗口

Question

如何使用用户32 .dll处理特定窗口？我在c＃工作。谢谢。有人能给我一个简短的例子吗？:)我很感激！ （方法：getwindowtext，show window，enumwindowcallback normal）。

Answer 1

尝试以下，

    // For Windows Mobile, replace user32.dll with coredll.dll
[DllImport("user32.dll", SetLastError = true)]
static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

// Find window by Caption only. Note you must pass IntPtr.Zero as the first parameter.

[DllImport("user32.dll", EntryPoint="FindWindow", SetLastError = true)]
static extern IntPtr FindWindowByCaption(IntPtr ZeroOnly, string lpWindowName);

// You can also call FindWindow(default(string), lpWindowName) or FindWindow((string)null, lpWindowName)

修改 您可以使用以下声明

 // Find window by Caption
        public static IntPtr FindWindow(string windowName)
        {
            var hWnd = FindWindow(windowName, null); 
            return hWnd;
        }

修改：2     这是代码的简明版本：

   public class WindowFinder
    {
        // For Windows Mobile, replace user32.dll with coredll.dll
        [DllImport("user32.dll", SetLastError = true)]
        static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

        public static IntPtr FindWindow(string caption)
        {
            return FindWindow(String.Empty, caption);
        }

    }
