所谓"绑架"就是把其他Win32程序的窗体嵌入到我们托管的WinForm中.网上已经用很多java版和Delphi版还有WPF的.我在这里补充 C#版的.
定义需要的Win32 API
[DllImport(
"
user32.dll
"
)]
private
static
extern
int
SetParent(IntPtr hWndChild,IntPtr hWndParent);
[DllImport(
"
user32.dll

)]
private
static
extern
bool
ShowWindowAsync(IntPtr hWnd,
int
nCmdShow);
[DllImport(
"
user32.dll
"
, SetLastError
=
true
)]
private
static
extern
bool
PostMessage(IntPtr hWnd,
uint
Msg,
int
wParam,
int
lParam);
[DllImport(
"
user32.dll
"
, EntryPoint
=
"
SetWindowPos
"
)]
private
static
extern
bool
SetWindowPos(IntPtr hWnd,
int
hWndInsertAfter,
int
X,
int
Y,
int
cx,
int
cy,
uint
uFlags);
[DllImport(
"
user32.dll
"
)]
private
static
extern
int
SendMessage(IntPtr hWnd,
uint
Msg,
int
wParam,
int
lParam);
[DllImport(
"
user32.dll
"
, SetLastError
=
true
, CharSet
=
CharSet.Auto)]
private
static
extern
uint
SetWindowLong(IntPtr hwnd,
int
nIndex,
uint
newLong);
[DllImport(
"

, SetLastError
=

private
static
extern
uint
GetWindowLong(IntPtr hwnd,

[DllImport(

CharSet.Auto)]
private
static
public
extern
bool
ShowWindow(IntPtr hWnd,
short
State);
private
const
int
HWND_TOP
=
0x0
;
private
const
int
WM_COMMAND
=
0x0112

private
const
int

启动我们需要绑架的程序
private
void
Form1_Load(
object
sender, EventArgs e)
{
p
=
new
Process();
//
需要启动的程序
p.StartInfo.FileName
=
@"
c:\windows\system32\notepad.exe
"
;
//
为了美观,启动的时候最小化程序
p.StartInfo.WindowStyle
=
ProcessWindowStyle.Minimized;
//
启动
p.Start();
//
这里必须等待,否则启动程序的句柄还没有创建,不能控制程序
Thread.Sleep(
1000
);
//
最大化启动的程序
ShowWindow(p.MainWindowHandle, (
short
)ShowWindowStyles.SW_MAXIMIZE);
//
设置被绑架程序的父窗口
SetParent(p.MainWindowHandle,
this
.Handle);
//
改变尺寸
ResizeControl();
}
//
控制嵌入程序的位置和尺寸
private
void
ResizeControl()
{
SendMessage(p.MainWindowHandle, WM_COMMAND, WM_PAINT,
0
);
PostMessage(p.MainWindowHandle, WM_QT_PAINT,
0
,
0
);
SetWindowPos(
p.MainWindowHandle,
HWND_TOP,
0
-
5
,
//
设置偏移量,把原来窗口的菜单遮住
0
-
41
,
(
int
)
this
.Width,
(
int
)
this
.Height
+
36
,
SWP_FRAMECHANGED);
SendMessage(p.MainWindowHandle, WM_COMMAND, WM_SIZE,
0
);
}
private
void
Form1_SizeChanged(
object
sender, EventArgs e)
{
ResizeControl();
}
需 要注意的是:ResizeControl()方法很重要,否则达不到我们预期的效果.
