HTA / VBScript window CMD output help required
Hi,
While deploying machines via WinPE 2.0 I'm using imagex.exe cmd to deploy an image to a pc & I need see imagex progress (so I can't just hide the CMD window.) Basically what I'm trying to do is create a nicer UI so I don't have to show the cmd window itself.. just the output it's giving, so far I have a hta that will display the output of the cmd window but it will only show this once the cmd is finished. I think I somehow need to create a loop to view the contents of the cmd output while it's still running and refresh the hta every few seconds.. maybe I need to output a temp file and refresh the hta from that while cmd is still running? I'm aiming to use this to redirect the output of any cmd window and maybe call it as a function whenever exe's are being run (file copy / directory listing / defrag etc). here is my code so far: =================== CMDout.hta =================== <html> <head><title>CMDOut</title> <HTA:APPLICATION ID="oHTA"; APPLICATIONNAME="CMDOut"; BORDER="thin"; BORDERSTYLE="normal"; SINGLEINSTANCE="no"; </head><body bgcolor="#E8E8E8" > <font size=2 face="Century Gothic, Tahoma, Arial" color="black"> <script language="VBScript" type="text/vbscript"> set objShell = CreateObject("WScript.Shell") strOut="" sub Window_Onload strComputer = "." Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2") Set colItems = objWMIService.ExecQuery("Select * From Win32_DesktopMonitor") For Each objItem in colItems intHorizontal = objItem.ScreenWidth intVertical = objItem.ScreenHeight Next intLeft = (intHorizontal - 640) / 2 intTop = (intVertical - 480) / 2 window.resizeTo 640,480 window.moveTo intLeft, intTop cmdarg="%comspec% /c ipconfig.exe " set objExCmd = objShell.Exec(cmdarg) strOut=objExCmd.StdOut.ReadAll Set regEx = New RegExp regEx.Pattern = "[\f\n\r\v]+" regEx.Global = True regEx.Multiline = True strOut = regEx.Replace(strOut, "<br>") CMDOut.innerHTML= strOut end sub //--> </script> <div id=CMDOut></div> ================ any assistance would be greatly appreciated! Thanks |

HTA / VBScript window CMD output help required
Hi Firebladeboy,
I investigated a lot on this one year ago. I also opened a case with Microsoft. IMAGEX has a /scroll option that should do what you need, the problem is that this option doesn't work at all. Microsoft recognized that this is a BUG in imagex and would be fixed in next release. Maybe you can try the imagex version coming with Windows Server 2008 AIK (I've not tryed). Basically the problem is due to the fact that any console application StdOut.Read included) are done whenever the buffer is full. Because the output of imagex is very small, this happens only when the execution completes and the buffer get flushed. If I could have the source code of imagex, I could fix it in 30 seconds, simply adding a buffer flush command after every output. Unfortunately imagex is not open source. There's no way to solve this problem with imagex. Even if you redirect output to a file, the file get written only upon program termination. The only solution I found is write (from scratch) a program in C++ and using the WIMGAPI to manage the WIM files. This works pretty good. If you want to use an HTA, the only solution I know is SmartWIM (it's an ActiveX that does the same job of imagex and more), but you should pay for it (I never tryed it anyway). -- Massimo "firebladeboy" <firebladeboy@discussions.microsoft.com> ha scritto nel messaggio news  1044789-7BDF-4CD6-9580-12D2B6E9F340@microsoft.com... |
