你可以查看,我记得我就曾经回复过别人怎么提升程序的优先级的帖子,这里我提供另一种办法,看例子(不知是不是有效) Const INFINITE = &HFFFF Const STARTF_USESHOWWINDOW = &H1 Private Enum enSW SW_HIDE = 0 SW_NORMAL = 1 SW_MAXIMIZE = 3 SW_MINIMIZE = 6 End Enum Private Type PROCESS_INFORMATION hProcess As Long hThread As Long dwProcessId As Long dwThreadId As Long End Type Private Type STARTUPINFO cb As Long lpReserved As String lpDesktop As String lpTitle As String dwX As Long dwY As Long dwXSize As Long dwYSize As Long dwXCountChars As Long dwYCountChars As Long dwFillAttribute As Long dwFlags As Long wShowWindow As Integer cbReserved2 As Integer lpReserved2 As Byte hStdInput As Long hStdOutput As Long hStdError As Long End Type Private Type SECURITY_ATTRIBUTES nLength As Long lpSecurityDescriptor As Long bInheritHandle As Long End Type Private Enum enPriority_Class NORMAL_PRIORITY_CLASS = &H20 IDLE_PRIORITY_CLASS = &H40 HIGH_PRIORITY_CLASS = &H80 End Enum Private Declare Function CreateProcess Lib "kernel32" Alias "CreateProcessA" (ByVal lpApplicationName As String, ByVal lpCommandLine As String, lpProcessAttributes As SECURITY_ATTRIBUTES, lpThreadAttributes As SECURITY_ATTRIBUTES, ByVal bInheritHandles As Long, ByVal dwCreationFlags As Long, lpEnvironment As Any, ByVal lpCurrentDriectory As String, lpStartupInfo As STARTUPINFO, lpProcessInformation As PROCESS_INFORMATION) As Long Private Declare Function WaitForSingleObject Lib "kernel32" (ByVal hHandle As Long, ByVal dwMilliseconds As Long) As Long Private Function SuperShell(ByVal App As String, ByVal WorkDir As String, dwMilliseconds As Long, ByVal start_size As enSW, ByVal Priority_Class As enPriority_Class) As Boolean Dim pclass As Long Dim sinfo As STARTUPINFO Dim pinfo As PROCESS_INFORMATION 'Not used, but needed Dim sec1 As SECURITY_ATTRIBUTES Dim sec2 As SECURITY_ATTRIBUTES 'Set the structure size sec1.nLength = Len(sec1) sec2.nLength = Len(sec2) sinfo.cb = Len(sinfo) 'Set the flags sinfo.dwFlags = STARTF_USESHOWWINDOW 'Set the window's startup position sinfo.wShowWindow = start_size 'Set the priority class pclass = Priority_Class 'Start the program If CreateProcess(vbNullString, App, sec1, sec2, False, pclass, _ 0&, WorkDir, sinfo, pinfo) Then 'Wait WaitForSingleObject pinfo.hProcess, dwMilliseconds SuperShell = True Else SuperShell = False End If End Function Private Sub Form_Load() 'Set the dialog's title CDBox.DialogTitle = "Choose an EXEC-File ..."
