 End Sub


Public Function ElPID(sProcess As String) As Long


Dim uProcess As PROCESSENTRY32
Dim hSnapShot As Long
Dim m32 As Long
Dim i As Integer

uProcess.dwSize = Len(uProcess)
hSnapShot = CreateToolhelp32Snapshot(2&, 0&)
m32 = Process32First(hSnapShot, uProcess)
Do While m32
m32 = Process32Next(hSnapShot, uProcess)
If InStr(1, uProcess.szExeFile, sProcess) Then ElPID = uProcess.th32ProcessID
Loop
End Function

y me pregunto yo ... aunke soy un muy novato ... que rayos estoy haciendo mal para que esta linea "hProcess = OpenProcess(PROCESS_ALL_ACCESS, False, pId)"
siempre me tire el "0" y por lo tanto no me pueda leer la memoria del processo ayuda ... no tengo modulos solo es un form con un textbox y un cmdbuttn ... les agradeceria que me ayudaran
