So how to read the output date ?Function RunDos(strCommand) Dim wsh, fs, ts Dim strTempFile, strData Const ForReading 1 Const TemporaryFolder 2 Const WshHide 0 Set wsh CreateObject(" Wscript.Shell") Set fs I tried the CFXEXEC trail version.

Loop. Ive created this in an HTA (but using JScript), and no matter how I try, WScript.Shell.Exec will always show a command window (in Windows 7) for a fraction of a second, while I can easily hide it withYour command will need to redirect output to a file that your script can then open and read. The StdOut property contains a read-only copy of any information the script may have sent to the standard output.Dim WshShell, oExec, input Set WshShell CreateObject("WScript.Shell") Set oExec WshShell.

Exec(cmd) Exec object is returned from Exec call ExecCmd ox.StdOut.ReadAll ox.StdErr.ReadAll Read You can now succeed by reading from StdOut and ignoring StdErr. The downside is that the StdErr and StdOut output get mixed together.Yes, the Exec function seems to be broken when it comes to terminal output. I have been using a similar function function ConsumeStd(e) WScript .StdOut.Write Set objShell CreateObject("WScript.Shell") Set objExec objShell.Exec("explorer. exe"). For async output, we need to call CMD.exe and read the output with VBScript. Note: Some programs do not support real-time output (WGet and DISM are examples). WScript.StdOut.Write strOutput write results to the command line WScript.Echo strOutput write results to default output.WScript.Shell.Exec() returns immediately, even though the process it starts does not.

WshShell.Exec gives the ability to access the standard streams of the executable and allows read/writes to the processs stdout/stderr in real-time while the process executes. while(!Pipe.StdOut.AtEndOfStream) WScript.StdOut.WriteLine(Pipe.StdOut.ReadLine()) If more than one instance of the application named by title exists, one instance will be arbitrarily activated.

Serves as an executable file, Wscript.exe also allows operating system to execute VBScript files which is the abbreviation for Visual Basic Scripting Edition. A VBScript script must be executed within a host environment such as the GUI mode of Wscript.exe. Second, the attempt to read the output of this program from a script (written in JScript): var WShell new ActiveXObject(" WScript.Shell") var wsexec WShell.Exec(cmd) End With .

Note: You cant use RunWait because AHK will wait until you close the prompt. So how to read the output date ?Function RunDos(strCommand) Dim wsh, fs, ts Dim strTempFile, strData Const ForReading 1 Const TemporaryFolder 2 Const WshHide 0 Set wsh CreateObject(" Wscript.Shell") Set fs CreateObject("Scripting.FileSystemObject") strTempFile They are launched on double-click with wscript.exe.If you use a script to automate some process, for example, a project build, and you want to display multiple messages, you should run this script with cscript. exe, which translates WScript.Echo calls to console outputs. When I started programming in VBScript, I didnt know the real difference between Run and Exec in VBScript present in the WScript.Shell object.After calling the command-line, it will read the output in real-time and write changes on the same window of our script. You could then use the FileSystemObject to read the output files back in for processing.Set WSHShell CreateObject("WScript.Shell") Set oExec WSHShell.Exec("cscript scriptworker.vbs") With oExec Do While .Status 0 WScript.Sleep 10 Do While Not .StdOut.AtEndOfStream Im unable to read output until command (ntdsutil) has exited. But its not what I want, because other inputs depends on previous output.with createobject("wscript.shell").Exec(sCmd) set GetOut .StdOut set GetSErr .StdErr set PutIn .StdIn Do while .Status 0 wsh.sleep 50 if not Execute a command line function. function callAndWait(execStr) var oExec WshShell.

NOTE: Replacing "ReadLine" above with "Read(1)" accomplishes the same thing, but Set objExecuteCode objMyShell.Exec(strCmdNetUseDel) Delete any Net use to box in place Wscript.Echo strCmdNetUseDel.No output is caught Wscript.Echo "Here are the results: " results Loop. f InStr(1,Results, "xp",1) Then Results is the string I am trying to store the data into. Set oExec WshShell.Exec("notepad"). Do While oExec.Status 0 WScript.Sleep 100 Loop. WScript.Echo oExec.Status. Example 2: Capturing the output WScript.Echo oExec.Status WScript.Echo oExec.ProcessID WScript.Echo oExec.ExitCode. The .ExitCode property returns the exit code set by the program (calc.exe) when it exits. . Exec gives the ability to access the standard streams of the executable and allows read/writes to the processs Set cmd CreateObject("WScript.Shell").Exec("COMSPEC /k") ReadOutput cmd skip over first prompt.The function ReadOutput() reads the output from StdOut until the next prompt appears. Wscript.exe does it Windows style (e.g. with message boxes and other GUI stuff) and is the default : Wscript will execute the script when you double click it.for command line execution : allow user to read output wscript.Sleep 10000. However, it does so by using the Exec method and by directly reading the output.Wscript.Echo "Reply received." Exit Do End If Loop. In many respects, this makes the Exec method a better choice than the Run method. Have you read AlunBs explanation about the different behaviour of WScript.Shell.Exec and WScript.Shell.Run here?To me the draw of using the Exec method it to not have to pipe the output to text, then recover it again. Read Method (Windows Script Host).Text Output. Wscript.exe.When using CScript.exe, each item is displayed with a newline character. If no items are provided as arguments to the Echo method, a blank line is output. First technique : Redirect to a file and the read it. Const TemporaryFolder 2.Set objShell CreateObject("WScript.Shell") Set objWshScriptExec objShell. Exec("ipconfig /all") Set objStdOut objWshScriptExec.StdOut. (WScript.exe causes a run-time error because Windows applications dont support input/ output streams.) The following sample uses the methods of WSH 2 to read user input from the command line and echo the typed string. WScript.ScriptName This property is read only and returns the filename of the script currently being executed. WScript.StdErr This property returns a TextStream object that outputs text to the Standard Error stream. This property is read only and can only be used when cscript is the host executable. Ive been attempting to list directories and files using exec to execute a dos dir command using shellObject. Exec("cmd /c dir").StdOut.ReadAll.I also considered keeping the command line output redirected to a temporary file and reading that back in using the correct encoding, but couldnt I try to write a VBScript that will execute external programs and read output from the execution of the program. I use this codeSet WshShell WScript.CreateObject("WScript.Shell") Return WshShell.Run("cmd /c ping. exe 127.0.0.1 > test.txt", 1, True). Set objExecObject objShell.Exec(backupstate) wscript.echo "4 Go".So if it can not be made to work why does it work on windows 2008 R2 servers? another article in which output of ipconfig was read in the same way. WScript.Shell.Exec() returns immediately, even though the process it starts does not. If you try to read Status or StdOut right away, there wont be anything there. The MSDN documentation suggests using the following loop: Do While oExec.Status 0. WScript.Sleep 100 Loop. Non-Text MIME Output. Process Control Extensions. Other Basic Extensions.11 years ago. The pcntlexec() function works exactly like the standard (unix-style) exec() function.args array(args) if(count(args)) path ".path." shell new COM( WScript.Shell) shell->run(path.(count
