c＃如何使用user32 dll處理特定窗口

Question

如何使用用戶32 .dll處理特定窗口？我在C＃工作。謝謝。有人能給我一個簡短的例子嗎？:)我會感激！ （方法：getwindowtext，show window，enumwindowcallback normal）。

Answer 1

嘗試以下，

// 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) 

編輯： 您可以使用這些聲明如下

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

編輯：2 下面是代碼的簡明版本：

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); 
     } 

    }
