c#调用winapi实现WinForm中嵌入EXE程序

添加引用：

using System.Diagnostics;

using System.Runtime.InteropServices;

定义：

Process process = null;

IntPtr appWin;

private string exeName = "";

[DllImport("user32.dll", EntryPoint = "GetWindowThreadProcessId", SetLastError = true, CharSet = CharSet.Unicode, ExactSpelling = true,

CallingConvention = CallingConvention.StdCall)]

private static extern long GetWindowThreadProcessId(long hWnd, long lpdwProcessId);

[DllImport("user32.dll", SetLastError = true)]

private static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

[DllImport("user32.dll", SetLastError = true)]

private static extern long SetParent(IntPtr hWndChild, IntPtr hWndNewParent);

[DllImport("user32.dll", EntryPoint = "GetWindowLongA", SetLastError = true)] private static extern long GetWindowLong(IntPtr hwnd, int nIndex);

[DllImport("user32.dll", EntryPoint = "SetWindowLongA", SetLastError = true)] private static extern long SetWindowLong(IntPtr hwnd, int nIndex, long dwNewLong);

//private static extern int SetWindowLong(IntPtr hWnd, int nIndex, IntPtr dwNewLong);

[DllImport("user32.dll", SetLastError = true)]

private static extern long SetWindowPos(IntPtr hwnd, long hWndInsertAfter, long x, long y, long cx, long cy, long wFlags);

[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", EntryPoint = "PostMessageA", SetLastError = true)] private static extern bool PostMessage(IntPtr hwnd, uint Msg, long wParam, long lParam);

private const int SWP_NOOWNERZORDER = 0x200;

private const int SWP_NOREDRAW = 0x8;

private const int SWP_NOZORDER = 0x4;

private const int SWP_SHOWWINDOW = 0x0040;

private const int WS_EX_MDICHILD = 0x40;

private const int SWP_FRAMECHANGED = 0x20;

private const int SWP_NOACTIVATE = 0x10;

private const int SWP_ASYNCWINDOWPOS = 0x4000;

private const int SWP_NOMOVE = 0x2;

private const int SWP_NOSIZE = 0x1;

private const int GWL_STYLE = (-16);

private const int WS_VISIBLE = 0x10000000;

private const int WM_CLOSE = 0x10;

private const int WS_CHILD = 0x40000000;

public string ExeName

{

get

{

return exeName;

}

set

{

exeName = value;

}

}

调用：

this.exeName = @"C:\Program Files\Kingview\Touchvew.exe";

try

{

// Start the process

process = System.Diagnostics.Process.Start(this.exeName);

// Wait for process to be created and enter idle condition

process.WaitForInputIdle();

// Get the main handle

appWin = process.MainWindowHandle;

}

catch (Exception ex)

{

MessageBox.Show(this, ex.Message, "Error");

}

// Put it into this form

SetParent(appWin, this.splitContainer1.Panel2.Handle);

// Remove border and whatnot

// SetWindowLong(appWin, GWL_STYLE, WS_VISIBLE);

// Move the window to overlay it on this window

MoveWindow(appWin, 0, 0, this.Width, this.Height, true);

在控件改变大小的时候，调用：

private void splitContainer1_Panel2_Resize(object sender, EventArgs e) {

if (this.appWin != IntPtr.Zero)

{

MoveWindow(appWin, 0, 0, this.splitContainer1.Panel2.Width, this.splitContainer1.Panel2.Height, true);

}

base.OnResize(e);

}

窗口退出时：

private void Form1_FormClosed(object sender, FormClosedEventArgs e)

{

process.Kill();

// Stop the application

//if (appWin != IntPtr.Zero)

//{

// // Post a colse message

// //PostMessage(appWin, WM_CLOSE, 0, 0);

// // Delay for it to get the message

// // System.Threading.Thread.Sleep(1000);

// // Clear internal handle

// appWin = IntPtr.Zero;

//}

//base.FormClosed(e);

}
