Shell command and rc with GetModuleUsage

Early with VB3 I had a program within I start a shell function and wait for the termination of the shell to continue within the function with the following code:
Private Declare Function GetModuleUsage Lib "Kernel32" (ByVal hModule As Integer) As Integer
...
comm = "xcopy " & fwininp & fwinout & " /e /s"

    X = Shell(comm, 1)
    While GetModuleUsage(X) > 0
        z = DoEvents()
    Wend
    If GetModuleUsage(X) < 0 Then
        MsgBox ("shell < 0 ")
    End If
...
Now with VB5, GetModuleUsage isn't found in any library I search !
Where can I found this function or by what can I replace it.
Is it another way to stay in my program while the shell is'nt terminated.
Thanks in advance.

Try this it's straight out of the MS Knowledge Base:

      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 Long
         hStdInput As Long
         hStdOutput As Long
         hStdError As Long
      End Type

      Private Type PROCESS_INFORMATION
         hProcess As Long
         hThread As Long
         dwProcessID As Long
         dwThreadID As Long
      End Type

      Private Declare Function WaitForSingleObject Lib "kernel32" (ByVal _
         hHandle As Long, ByVal dwMilliseconds As Long) As Long

      Private Declare Function CreateProcessA Lib "kernel32" (ByVal _
         lpApplicationName As Long, ByVal lpCommandLine As String, ByVal _
         lpProcessAttributes As Long, ByVal lpThreadAttributes As Long, _
         ByVal bInheritHandles As Long, ByVal dwCreationFlags As Long, _
         ByVal lpEnvironment As Long, ByVal lpCurrentDirectory As Long, _
         lpStartupInfo As STARTUPINFO, lpProcessInformation As _
         PROCESS_INFORMATION) As Long

      Private Declare Function CloseHandle Lib "kernel32" (ByVal _
         hObject As Long) As Long

      Private Const NORMAL_PRIORITY_CLASS = &H20&
      Private Const INFINITE = -1&

      Public Sub ExecCmd(cmdline$)
         Dim proc As PROCESS_INFORMATION
         Dim start As STARTUPINFO

         ' Initialize the STARTUPINFO structure:
         start.cb = Len(start)

         ' Start the shelled application:
         ret& = CreateProcessA(0&, cmdline$, 0&, 0&, 1&, _
            NORMAL_PRIORITY_CLASS, 0&, 0&, start, proc)

         ' Wait for the shelled application to finish:
         ret& = WaitForSingleObject(proc.hProcess, INFINITE)
         ret& = CloseHandle(proc.hProcess)
      End Sub


Add the following code the Form_Click() event procedure of Form1:

      Sub Form_Click ()
         ExecCmd "notepad.exe"
         MsgBox "Process Finished"
      End Sub


Press the F5 key to run the application.

Using the mouse, click the Form1 window. At this point the Notepad application is shelled.
