Hi, I am pretty new at this formu. So first of all to say hello. And also sorry for my English. I have one question about VB. I made one program to map network drives with password and user name, actuality they are CNC machines. Everything works Ok, but I would like to know if there is any possibility to make some VB app that will show me is this CNC is working or it is in stop mode. Software on CNC is based on windows nt system. He reds NC programs stored on machine, that was copied on machine fom pc. Any idea how to develop something like that. Any idea how to check if someone is reading file on remote disk? ok so far i have something, with vb script, just for testing. but problem is that I can only check one file, but not all files in folder folder Code: sLogFile = "L:\Razno\Vrijeme\" Set oFSO = CreateObject("Scripting.FileSystemObject") bUpdFinished = False On Error Resume Next Set f = oFSO.OpenTextFile(sLogFile, ForAppending, True) If Err.Number = 70 Then 'Ako je prostup zabranjen( on Croatian) ' Pricekaj pola sekunde( on Croatian) WScript.Echo "u radu" WScript.Sleep 500 'provjeri i samo nastavi dalje( on Croatian) ElseIf Err.Number <> 0 then WScript.Echo "u radu" & Err.Number bUpdFinished = True Else 'ako radi izbaci WScript.Echo "ne radi" bUpdFinished = True End If so if i put for example sLogFile = "L:\Razno\Vrijeme\test.xls" for this particular file works fine, but how can I do that for all file in folder. Also one more question can it be don??? Input box - to input several files by user and than check them by code above please helo
