Question

VB中为何OpenProcess总是返回0????

Dim hwnd As Long
Dim pid As Long
Dim pHandle As Long
hwnd = FindWindow(vbNullString, "计算器")
GetWindowThreadProcessId hwnd, pid
pHandle = OpenProcess(STANDARD_RIGHTS_REQUIRED Or SYNCHRONIZE Or SPECIFIC_RIGHTS_ALL, False, pid)
Label1.Caption = hwnd & Chr(13) & pid & Chr(13) & pHandle

其中hwnd 和pid的值都已经获取
