我选择的编程工具当然是Visual Basic NET2003，实话说Microsoft .NET Framework SDK 提供的功能实在不感恭维，微软好象又要将所有走上光明大道的.NET程序员拖入API的黑暗时代，指针、句柄、地址操作，最令人恼火就是没有为VB.net程序做WinCE的API 声明（令人怀念VB6的API浏览器）很快我就在如何启动手机中的应用程序的代码上困住了，Net没有为WinCE提供Process 对象这种不付责任的做法害得我好苦啊！
开始时声明时老是将ShellExecuteEx 和CreateProcess这两个熟悉得不能再熟悉的Win32在VB 6中的声明直接粘到程序中，仅是将VB6的long改为NET的int32，结果老是报错。在网上查了N天资料，才发现原来Win CE的核心API都是在一个coredll.dll文件中，使得我差点没气死！还有一点是SHELLEXECUTEINFO结构中的lpFile这种指向字符串常量的指针由于字符的编码问题不能象在Win32编程中简单声明为String类型，所在必须声明为Intptr，这样问题就出现了，使用ShellExecuteEx函数必须使用微软在VB.net中不直接提供的指针操作，所以我只好根据网上的资料改写了一个VB.net对内存指针的封装类，详细代码及解释如下（新建一个模块，将以下代码粘贴进去即可使用）：
Imports System.Runtime.InteropServices '引及Net框架中对底层操作支持的命名空间
Public Class clsDAMSMobileMarshal '我写的内存管理类

Public Declare Function LocalAlloc Lib "coredll.dll" Alias "LocalAlloc" (ByVal wFlags As Int32, _

#End Region

Return LocalAlloc(LPTR, ni_i32Size)
End Function
Public Shared Function fnFreeHLocal(ByRef ni_pLocal As IntPtr) As Int32
REM 释放指定的内存块柄
Dim ti32FunctionReturnValue As Int32
If ni_pLocal.Equals(IntPtr.Zero) = False Then
ti32FunctionReturnValue = (LocalFree(ni_pLocal.ToInt32))
If ti32FunctionReturnValue = 0 Then
ni_pLocal = IntPtr.Zero
End If
End If
Return (ti32FunctionReturnValue)
End Function
Public Shared Function fnReAllocHLocal(ByVal ni_pIn As IntPtr, ByVal ni_i32Size As Int32) As IntPtr
'对指定的内存块重新定义大小
Return LocalReAlloc(ni_pIn, ni_i32Size, LMEM_MOVEABLE)
End Function
Public Shared Function fnStringToHLocalUni(ByVal ni_strIn As String) As IntPtr
'将指定的字符串复制到一个内存块中，并返回该内存块的指针，这个指针必须使用fnFreeHLocal函数释放
Dim ti32StringBufLength As Int32
Dim tpTempA As IntPtr
If Not (ni_strIn Is Nothing) Then
If ni_strIn.Length = 0 Then
Return IntPtr.Zero
Else
ti32StringBufLength = (ni_strIn.Length + 1) * 2 ' 包括最后一个中止字符
tpTempA = fnAllocHLocal(ti32StringBufLength)
If tpTempA.Equals(IntPtr.Zero) = False Then '申请内存成功
Marshal.Copy(ni_strIn.ToCharArray, 0, tpTempA, ni_strIn.Length)
Return tpTempA
End If
End If
End If
End Function
End Class
有了这个辅助函数，以下的API调用就简单了，只需正确声明即可，以下是ShellExecuteEx及CreateProcess涵数及其结构的正确声明(同样是将代码粘贴到一个新建模块中即可调用)：
