C#可调用API接口来获取窗口句柄,发送消息控制其余程序窗体大小
根据标题获取窗口句柄
using System; using System.Runtime.InteropServices; namespace tstfindwindow { /// /// Class1 的摘要说明。 /// class Class1 { [DllImport( "User32.dll ")] public static extern System. IntPtr FindWindowEx(System. IntPtr parent, System. IntPtr childe, string strclass, string strname); /// /// 应用程序的主入口点。 /// [STAThread] static void Main(string[] args) { // //TODO: 在此处添加代码以启动应用程序 // IntPtr p=FindWindowEx(System.IntPtr.Zero,System.IntPtr.Zero,null,"窗口标题"); } }
发送消息控制最大、最小
[DllImport("user32.dll", EntryPoint = "PostMessage")] public static extern int PostMessage(IntPtr hwnd, int wMsg, int wParam, int lParam); public const int WM_SYSCOMMAND = 0x112; public const int SC_MINIMIZE = 0xF020; public const int SC_MAXIMIZE = 0xF030; private void button1_Click(object sender, EventArgs e) { PostMessage(Handle, WM_SYSCOMMAND, SC_MINIMIZE, 0); }
