1.新建winform程序，添加一個Panel控件和一個button控件，winform窗體命名為：Mainform；
2.新建一個類文件，方便引用，命名為：exetowinform；
3.Mainform中cs代碼如下：
exetowinform fr = null; private void button1_Click(object sender, EventArgs e) { OpenFileDialog Oppf = new OpenFileDialog(); Oppf.ShowDialog(); if (Oppf.FileName != "") { panel1.Controls.Clear(); fr = new exetowinform(panel1, ""); fr.Start(Oppf.FileName); } }
4.exetowinform類文件代碼如下：
public class exetowinform { EventHandler appIdleEvent = null; Control ParentCon = null; string strGUID = ""; public exetowinform(Control C, string Titlestr) { appIdleEvent = new EventHandler(Application_Idle); ParentCon = C; strGUID = Titlestr; } /// <summary> /// 將屬性<code>AppFilename</code>指向的應用程序打開並嵌入此容器 /// </summary> public IntPtr Start(string FileNameStr) { if (m_AppProcess != null) { Stop(); } try { ProcessStartInfo info = new ProcessStartInfo(FileNameStr); info.UseShellExecute = true; info.WindowStyle = ProcessWindowStyle.Minimized; m_AppProcess = System.Diagnostics.Process.Start(info); m_AppProcess.WaitForInputIdle(); Application.Idle += appIdleEvent; } catch { if (m_AppProcess != null) { if (!m_AppProcess.HasExited) m_AppProcess.Kill(); m_AppProcess = null; } } return m_AppProcess.Handle; } /// <summary> /// 確保應用程序嵌入此容器 /// </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; return; } while (m_AppProcess.MainWindowHandle == IntPtr.Zero) { Thread.Sleep(100); m_AppProcess.Refresh(); } Application.Idle -= appIdleEvent; EmbedProcess(m_AppProcess, ParentCon); } /// <summary> /// 應用程序結束運行時要清除這里的標識 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> void m_AppProcess_Exited(object sender, EventArgs e) { m_AppProcess = null; } /// <summary> /// 將屬性<code>AppFilename</code>指向的應用程序關閉 /// </summary> public void Stop() { if (m_AppProcess != null)// && m_AppProcess.MainWindowHandle != IntPtr.Zero) { try { if (!m_AppProcess.HasExited) m_AppProcess.Kill();

遇到的問題
我要打開一個exe文件，文件打開了，但是並沒有嵌入到我的窗體中。
解決方法
經過一番嘗試，發現通過程序Process.MainWindowHandle得到的句柄和通過FindWindow(null, "程序名稱")得到的句柄不一致。
然后得出方案；
IntPtr hWnd = FindWindow(null, "文件名"); IntPtr appWnd = app.MainWindowHandle; ShowWindow(appWnd, 0);
隱藏掉process得到的程序窗口，然后執行
try { // Put it into this form SetParent(hWnd, control.Handle); } catch (Exception) { } try { // Remove border and whatnot SetWindowLong(new HandleRef(this, hWnd), GWL_STYLE, WS_VISIBLE); // SendMessage(app.MainWindowHandle, WM_SETTEXT, IntPtr.Zero, strGUID); } catch (Exception) { } try { // Move the window to overlay it on this window MoveWindow(hWnd, 0, 0, control.Width, control.Height, true); } catch (Exception) { }
好了，到這問題基本上就解決了。
