序
之前有學弟為了在一台有Win CE環境的PDA上開發應用程式傷腦筋
原因是Visual Studio 2005提供.Net Compact Framework 2.0 無法發佈在比較舊版的Win CE上，
所以就使用.Net Compact Framework 1.1在開發，然後就出現了一個問題，
要呼叫外部程式的話，去MSDN找現有函式只有2.0的才有，
1.1的就要用我下面說的東西了~
PS.我在Google上找 VB 範例，能直接用不會有錯的都不在前面的搜尋結果，讓我花了不少功夫~
開發環境
- Microsoft Visual Studio 2005
- 語言：VB
程式功能
- 在.Net Compact Framework 1.1的環境下，使用VB程式呼叫外部的程式
- 等外部程式結束後，才繼續往下一行程式執行
開發要點
開一個模組，來放下面的程式
Module MyProcessCreater
Declare Function CreateProcess Lib "CoreDll.dll" (ByVal imageName As String, ByVal cmdLine As String, ByVal lpProcessAttributes As IntPtr, ByVal lpThreadAttributes As IntPtr, ByVal boolInheritHandles As Int32, ByVal dwCreationFlags As Int32, ByVal lpEnvironment As IntPtr, ByVal lpszCurrentDir As IntPtr, ByVal si As Byte(), ByVal pi As ProcessInfo) As Integer
Declare Function WaitForSingleObject Lib "CoreDll.dll" (ByVal Handle As IntPtr, ByVal Wait As Int32) As Int32
Declare Function GetLastError Lib "CoreDll.dll" () As Int32
Declare Function CloseHandle Lib "CoreDll.dll" (ByVal Handle As IntPtr) As Int32
Public Class ProcessInfo
Public hProcess As IntPtr
Public hThread As IntPtr
Public ProcessId As Int32
Public ThreadId As Int32
End Class 'ProcessInfo
Public Function CreateProcess(ByVal ExeName As String, ByVal CmdLine As String, ByVal pi As ProcessInfo) As Boolean
Dim INFINITE As Int32
INFINITE = &HFFFFFFFF
Dim WAIT_OBJECT_0 As Int32 = 0
Dim result As Int32
If pi Is Nothing Then
pi = New ProcessInfo
End If
Dim si(128) As Byte
result = CreateProcess(ExeName, CmdLine, IntPtr.Zero, IntPtr.Zero, 0, 0, IntPtr.Zero, IntPtr.Zero, si, pi) '呼叫外部程式
If 0 = result Then
Return False
End If
result = WaitForSingleObject(pi.hProcess, INFINITE) '等外部程式結束
CloseHandle(pi.hThread)
CloseHandle(pi.hProcess)
If WAIT_OBJECT_0 <> result Then
Return False
End If
Return True
End Function
End Module
然後在要呼叫的地方加入以下程式
CreateProcess("要呼叫的程式路徑", "", Nothing)
第一個參數："要呼叫的程式路徑" 如"\Windows\iexplore.exe"
第二個參數：是外部程式用的參數
第三個參數：我也不清處怎麼用
