Running command line silently with VbScript and getting output

Question

I want to be able to run a program through command line and I want to start it with VbScript   I also want to get the output of the command line and assign it to a variable and I want all this to be done silently without cmd windows popping up   I have managed two things separately but not together  Here s what I got so far  Run the command from cmd and get output   Dim WshShell  oExec Set WshShell   WScript CreateObject  WScript Shell   Set oExec   WshShell Exec  C  snmpget -c public -v 2c 10 1 1 2  1 3 6 1 4 1 6798 3 1 1 1 5 1   x   oExec StdOut ReadLine Wscript Echo x   The above script works and does what I want except that cmd pops up for a brief moment    Here s a script that will run silently but won t grab the output  Set WshShell   WScript CreateObject  WScript Shell   Return   WshShell Run  C  snmpset -c public -v 2c -t 0 10 1 1 2  1 3 6 1 4 1 6798 3 1 1 1 7 1 i 1   0  true    Is there a way to get these two to work together   Let me give you a background on why I want do to this   I am basically polling a unit every 5-10 minutes and I am going to get the script to email or throw a message box when a certain condition occurs but I don t want to see cmd line popping up all day long on my computer  Any suggestions  Thanks

I have taken this and various other comments and created a bit more advanced function for running an application and getting the output   Example to Call Function  Will output the DIR list of C   for Directories only  The output will be returned to the variable CommandResults as well as remain in C  OUTPUT TXT   CommandResults   vFn Sys Run CommandOutput  CMD EXE  C DIR C    AD  1 1  C  OUTPUT TXT  0 1    Function  Function vFn Sys Run CommandOutput  Command  Wait  Show  OutToFile  DeleteOutput  NoQuotes   Run Command similar to the command prompt  for Wait use 1 or 0  Output returned and  stored in a file   Command   The command line instruction you wish to run   Wait   1 0  1 will wait for the command to finish before continuing   Show   1 0  1 will show for the command window   OutToFile   The file you wish to have the output recorded to   DeleteOutput   1 0  1 deletes the output file  Output is still returned to variable   NoQuotes   1 0  1 will skip wrapping the command with quotes  some commands wont work                  if you wrap them in quotes   ----------------------------------------------------------------------------------------   On Error Resume Next    On Error Goto 0     Set f objShell   CreateObject  Wscript Shell       Set f objFso   CreateObject  Scripting FileSystemObject       Const ForReading   1  ForWriting   2  ForAppending   8        VARIABLES         If OutToFile      Then OutToFile    TEMP TXT          tCommand   Command         If Left Command 1  lt  gt      And NoQuotes  lt  gt  1 Then tCommand         amp  Command  amp               tOutToFile   OutToFile         If Left OutToFile 1  lt  gt      Then tOutToFile         amp  OutToFile  amp               If Wait   1 Then tWait   True         If Wait  lt  gt  1 Then tWait   False         If Show   1 Then tShow   1         If Show  lt  gt  1 Then tShow   0        RUN PROGRAM         f objShell Run tCommand  amp    gt    amp  tOutToFile  tShow  tWait        READ OUTPUT FOR RETURN         Set f objFile   f objFso OpenTextFile OutToFile  1            tMyOutput   f objFile ReadAll           f objFile Close           Set f objFile   Nothing        DELETE FILE AND FINISH FUNCTION         If DeleteOutput   1 Then           Set f objFile   f objFso GetFile OutToFile              f objFile Delete             Set f objFile   Nothing           End If         vFn Sys Run CommandOutput   tMyOutput         If Err Number  lt  gt  0 Then vFn Sys Run CommandOutput     lt 0 gt           Err Clear         On Error Goto 0       Set f objFile   Nothing       Set f objShell   Nothing   End Function

Mark Cidade  Thanks Mark  This solved few days of research on wondering how should I call this from the PHP WshShell  So thanks to your code  I figured     function   exec  tmppath   cmd        WshShell   new COM  WScript Shell        tmpf   rand 1000  9999    tmp      Temp file     tmpfp    tmppath      tmpf     Full path to tmp file      oExec    WshShell- gt Run  cmd  c  cmd -c      gt     tmpfp  0  true          return  oExec    0   true   false     Return True False after exec    return  tmpf      This is what worked for me in my case  Feel free to use and modify as per your needs  You can always add functionality within the function to automatically read the tmp file  assign it to a variable and or return it and then delete the tmp file  Thanks again  Mark

Look for assigning the output to Clipboard  in your first script  and then in second script parse Clipboard value

I am pretty new to all of this  but I found that if the script is started via CScript exe  console scripting host  there is no window popping up on exec    so when running    cscript myscript vbs   nologo   any  Exec   calls in the myscript vbs do not open an extra window  meaning that you can use the first variant of your original solution  using exec     Note that the two forward slashes in the above code are intentional  see cscript

You can redirect output to a file and then read the file   return   WshShell Run  cmd  c C  snmpset -c      gt  c  temp output txt   0  true   Set fso    CreateObject  Scripting FileSystemObject   Set file   fso OpenTextFile  c  temp output txt   1  text   file ReadAll file Close
