windows mobile 5.0 进程管理、窗体管理、重启和关闭操作系统

1、进程管理 ：在NET Compact Framework里进程管理的函数相对要比net Framework里要简化，不过仍然可以比较好的控制程序进程。

A.启动进程:在启动进程后返回进程的id

public
 
static
 
int
 StartProcess(
string
 fileName)

        {

int
 progressID 
=
 
0
;


try


            {

//
这个目录是动态的


                progressID 
=
 System.Diagnostics.Process.Start(fileName).Id;

return
 progressID;

            }

catch
 
//
(Exception ex)


            {

//
throw ex;


                
return
 
0
;

            }

        }

B.获取当前进程的ID

public
 
static
 
int
 GetCurrentProcessID()

        {

             Process currentProcess 
=
 Process.GetCurrentProcess();

int
 CurrentProcessID 
=
 currentProcess.Id;

return
 CurrentProcessID;

        }

C.终止当前进程

public
 
static
 
void
 KillCurrentProcess()

        {

            System.Diagnostics.Process.GetCurrentProcess().Kill();

        }

D.通过进程ID来终止进程

</returns>


        
public
 
static
 
bool
 KillProcess(
int
 progressID)

        {

try


            {

                System.Diagnostics.Process.GetProcessById(progressID).Kill();

return
 
true
;

            }

catch
 
//
(Exception ex)


            {

//
throw ex;


                
return
 
false
;

            }

        }

2、窗体管理。在NET Compact Framework（2.0）的窗体类（System.Windows.Forms.Form)）虽然提供WindowsState属性，这个属性是 FormWindowState 枚举类型，在枚举中只有Normal 和 Maximized，不过不能通过Maximized来控制窗体最小，同时也无法控制窗体的关闭。要是实现关闭和最小化只能通过调用api来实现。下面是 有关代码：

-->[DllImport(
"
coredll.dll
"
)]

private
 
extern
 
static
 
bool
 ShowWindow(IntPtr hWnd, 
int
 nCmdShow);

        [DllImport(
"
coredll.dll
"
)]

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

///
最小化窗体


public
 
static
 
void
 WindowsMin(
string
 frmTextName)

        {


            IntPtr hwnd 
=
 FindWindow(
null
, frmTextName);

            ShowWindow(hwnd, 
6
);

        }

///
隐藏窗体


        
public
 
static
 
void
 WindowHide(
string
 frmTextName)

        {

            IntPtr hwnd 
=
 FindWindow(
null
, frmTextName);

            ShowWindow(hwnd, 
0
);

        }

3、重启和关闭操作系统。同样是调用api来完成。

        [DllImport(
"
Aygshell.dll
"
)]

static
 
extern
 
bool
 ExitWindowsEx(
uint
 uFlags, 
int
 dwReserved);

private
 
const
 
uint
 EWX_REBOOT 
=
 
2
;

private
 
const
 
uint
 EWX_POWEROFF 
=
 
8
;


///
重启操作系统


        
public
 
static
 
void
 RootWindows()

        {

            ExitWindowsEx(EWX_REBOOT, 
0
);

        }


///
关闭操作系统


        
public
 
static
 
void
 ShutDownWindows()

        {

            ExitWindowsEx(EWX_POWEROFF, 
0
);

        }

以上代码的运行环境和开发环境：windows mobile5.0 +ppc sdk +vs2005
