C#winform嵌套另一个exe程序
一共有二种方法,也不知道作者从哪里复制来的,先感谢原作者。
首先建立一个程序,加2个按钮,为了区分,界面修改成红色。
第一种
1.建立一个主程序,加一个panel1,为了区分背景是绿色
2.代码调用
3.所有代码
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Diagnostics; using System.Drawing; using System.Linq; using System.Runtime.InteropServices; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; namespace WindowsFormsApp1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } /// <summary> /// 嵌入外部exe /// </summary> public class EmbeddedExeTool { [DllImport("User32.dll", EntryPoint = "SetParent")] private static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewparent); [DllImport("user32.dll", EntryPoint = "ShowWindow")] private static extern int ShowWindow(IntPtr hwnd, int nCmdShow); [DllImport("user32.dll", SetLastError = true)] private static extern bool MoveWindow(IntPtr hwnd, int x, int y, int cx, int cy, bool repaint); [DllImport("user32.dll")] private static extern int GetWindowLong(IntPtr hWnd, int nIndex); [DllImport("user32.dll")] private static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong); [DllImport("user32.dll", SetLastError = true)] private static extern IntPtr FindWindow(string lpClassName, string lpWindowName); IntPtr WindowHandle = IntPtr.Zero; private const int WS_THICKFRAME = 262144; private const int WS_BORDER = 8388608; private const int GWL_STYLE = -16; private const iandroidnt WS_CAPTION = 0xC00000; private Process proApp = null; private Control ContainerControl = null; private const int WS_VISIBLE = 0x10000000; [DllImport("user32.dll", EntryPoint = "SetWindowLong", CharSet = CharSet.Auto)] private static extern IntPtr SetWindowLongPtr32(HandleRef hWnd, int nIndex, int dwNewLong); [DllImport("user32.dll", EntryPoint = "SetWindowLongPtr", CharSet = CharSet.Auto)] private static extern IntPtr SetWindowLongPtr64(HandleRef hWnd, int nIndex, int dwNewLong); private IntPtr SetWindowLong(HandleRef hWnd, int nIndex, int dwNewLong) { if (IntPtr.Size == 4) { return SetWindowLongPtr32(hWnd, nIndex, dwNewLong); } return SetWindowLongPtr64(hWnd, nIndex, dwNewLong); } /// <summary> /// 加载外部exe程序到程序容器中 /// </summary> /// <param name="control">要显示exe的容器控件</param> /// <param name="exepath">exe的完整绝对路径</param> public void LoadEXE(Control control, string exepath) { ContainerControl = control; control.SizeChanged += Control_SizeChanged; ProcessStartInfo info = new ProcessStartInfo(exepath); info.WindowStyle = ProcessWindowStyle.Minimized; info.UseShellExecute = false; info.CreateNoWindow = false; proApp = Process.Start(info); Application.Idle += Application_Idle; EmbedProcess(proApp, control); } /// <summary> /// 加载外部exe程序到程序容器中 /// </summary> /// <param name="form">要显示exe的窗体</param> /// <param name="exepath">exe的完整绝对路径</param> public void LoadEXE(Form form, string exepath) { ContainerControl = form; form.SizeChanged += Control_SizeChanged; proApp = new Process(); proApp.StartInfo.UseShellExecute = false; proApp.StartInfo.CreateNoWindow = false; proApp.StartInfo.WindowStyle = ProcessWindowStyle.Minimized; proApp.StartInfo.FileName = exepath; proApp.StartInfo.Arguments = Process.GetCurrentProcess().Id.ToString(); proApp.Start(); Application.Idle += Application_Idle; EmbedProcess(proApp, form); } /// <summary> /// 确保应用程序嵌入此容器 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void Application_Idle(object sender, EventArgs e) { www.devze.com if (this.proApp == null || this.proApp.HasExited) js { this.proApp = null; Application.Idle -= Application_Idle; return; } if (proApp.MainWindowHandle == IntPtr.Zero) return; Application.Idle -= Application_Idle; EmbedProcess(proApp, ContainerControl); } /// <summary> /// 将指定的程序嵌入指定的控件 /// </summary> private void EmbedProcess(Process app, Control control) { // Get the main handle if (app == null || app.MainWindowHandle == IntPtr.Zero || control == null) return; try { // Put it into this form SetParent(app.MainWindowHandle, control.Handle); // Remove border and whatnot SetWindowLong(new HandleRef(this, app.MainWindowHandle), GWL_STYLE, WS_VISIBLE); ShowWindow(app.MainWindowHandle, (int)ProcessWindowStyle.Maximized); MoveWindow(app.MainWindowHandle, 0, 0, control.Width, control.Height, true); } catch (Exception ex3) { Console.WriteLine(ex3.Message); } } /// <summary> /// 嵌入容器大小改变事件 /// </summary> private void Control_SizeChanged(object sender, EventArgs e) { if (proApp == null) { return; } if (proApp.MainWindowHandle != IntPtr.Zero && ContainerControl != null) { MoveWindow(proApp.MainWindowHandle, 0, 0, ContainerControl.Width, ContainerControl.Height, true); } } } private void Form1_Load(object sender, EventArgs e) { EmbeddedExeTool exetool = new EmbeddedExeTool(); //WindowsFormsApp4.exe 为要嵌入外部exe的具体路径 exetool.LoadEXE(panel1, AppjsDomain.CurrentDomain.BaseDirectory+ "WindowsFormsApp4.exe");//debug下面的文件夹 } } }
4.效果很好。
红配绿,绝配。
第二种
和第一种方式有点不一样。
1.建立一个winform主程序,为了区分背景是绿色
2.把代码直接复制进去,修改命名空间,再加上一个load事件即可
3.代码
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.Diagnostics; using System.Runtime.InteropServices; namespace WindowsFormsApp1 { public partial class Form1 : Form { private const int GWL_STYLE = (-16); private const int WS_VISIBLE = 0x10000000; EventHandler appIdleEvent = null; Action<object, EventArgs> appIdleAction = null; Process m_AppProcess; [DllImport("user32.dll", EntryPoint = "SetWindowLong", CharSet = CharSet.Auto)] public static extern IntPtr SetWindowLongPtr32(HandleRef hWnd, int nIndex, int dwNewLong); [DllImport("user32.dll", EntryPoint = "SetWindowLongPtr", CharSet = CharSet.Auto)] public static extern IntPtr SetWindowLongPtr64(HandleRef hWnd, int nIndex, int dwNewLong); [DllImport("user32.dll", SetLastError = true)] private static extern long SetParent(IntPtr hWndChild, IntPtr hWndNewParent); //SetParent(IntPtr hWndChild, IntPtr hWndNewParent);这个方法很重要,就是将hWndChild指向开启exe的窗体嵌入到hWndNewParent窗体的某个控件上,或者是窗体本 身的容器 [DllImport("user32.dll", SetLastError = true)] private static extern bool MoveWindow(IntPtr hwnd, int x, int y, int cx, int cy, bool repaint); // MoveWindow(IntPtr hwnd, int x, int y, int cx, int cy, bool repaint);这个方法是windows的api,见名知意,是移动hwnd所指的窗体到指定的位置,并且指定是否需要重绘 public static IntPtr SetWindowLong(HandleRef hWnd, int nIndex, int dwNewLong) { if (IntPtr.Size == 4) { return SetWindowLongPtr32(hWnd, nIndex, dwNewLong); } return SetWindowLongPtr64(hWnd, nIndex, dwNewLong); } public Form1() { InitializeComponent(); appIdleAction = new Action<object, EventArgs>(Application_Idle); appIdleEvent = new EventHandler(appIdleAction); } /// <summary> /// 确保应用程序嵌入此容器,再次确认exe嵌入,如果不调用这个方法,程序不一定能嵌入外部exe /// </summary> /// <param name="sender"></param> /// <param name="e"></param> void Application_Idle(object sender, EventArgs e) { if (this.m_AppProcess == null || this.m_AppProcess.HasExited) { this.m_AppProcess = null; Application.Idle -= appIdleEvent;//这一步一直不知道有什么用,但是不用这行代码程序有时候能嵌入有时候又不行 return; } if (m_AppProcess.MainWindowHandle == IntPtr.Zero) return; Application.Idle -= appIdleEvent; EmbedProcess(m_AppProcess, this); } /// <summary> /// 将指定的程序嵌入指定的控件 /// </summary> private void EmbedProcess(Process app, Control control) { // Get the main handle if (app == null || app.MainWindowHandle == IntPtr.Zero || control == null) return; try { // Put it into this form SetParent(app.MainWindowHandle, control.Handle); } catch (Exception ex1) { Console.WriteLine(ex1.Message); } try { // Remove border and whatnot SetWindowLong(new HandleRef(this, app.MainWindowHandle), GWL_STYLE, WS_VISIBLE); } catch (Exception ex2) { Console.WriteLine(ex2.Message); } try { MoveWindow(app.MainWindowHandle, 0, 0, control.Width, control.Height, true); } catch (Exception ex3) { Console.WriteLine(ex3.Message); } } private void Form1_Load(object sender, EventArgs e) { //以下这段代码是通过命令行方式调起一个exe程序,获取这个程序的句柄然后嵌入主的winform窗体中 ProcessStartInfo info = new ProcessStartInfo(AppDomain.CurrentDomain.BaseDirectory + "WindowsFormsApp4.exe");//debug下面的文件夹 info.WindowStyle = ProcessWindowStyle.Minimized; info.UseShellExecute = false; info.CreateNoWindow = false; m_AppProcess = System.Diagnostics.Process.Start(info); Application.Idle += appIdleEvent; try { EmbedProcess(m_AppProcess, this); } catch (Exception ex) { Console.WriteLine(ex.Message); } } } }
4.效果
可见,第一种和第二种的效果有所区别的。
拓展。
WPF签入winform
1.依然用上面的winform程序,把输出类型改成类库
2.建立一个WPF程序,引用System.Windows.Forms和WindowsFormsIntegration,红色。绿色是步骤1生产的dll
3.在wpf中增加WindowsFormsHost控件
4.cs后台代码
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Navigation; using System.Windows.Shapes; using WindowsFormsApp4; namespace WpfApp1 { /// <summary> /// MainWindow.xaml 的交互逻辑 /// </summary> public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); Form1 mainform = new Form1(); mainfwww.devze.comorm.TopLevel = false; winform.Child = mainform; } } }
5.效果
总结
以上为个人经验,希望能给大家一个参考,也希望大家多多支持我们。
