_RunDos and Dos Box

4 posts in this topic

#1 ·  Posted (edited)

I've been trying to get a dos subst command running.

I have discovered that it hangs if there is a dos box {"Command Prompt" already open [as I had, to un-subst it during the test phase].In fact, it hung to the extent that closing the program from the tray menu failed, and I had to 3-finger salute and stop the autoit3 wrapper process!

Is this a known problem? Is it confined to certain commands?

As this will be running off a CD on someone else's PC I need to check if there's a dos box open and kill it if so - or is there a way round this other than writing a batch file, running it, and then deleting it?

My code is

#include <Process.au3>

 $sSubst = "subst "& "B:" & " D:\cd_temp"  ;" c:\NHS_CFH_DICOM_Images\encryption")
 ;MsgBox (0, "$sSubst", $sSubst)

 $rc= _RunDOS ($sSubst)
 Exit

There is a way round it BUT I just ran your code with 3 x Dos prompts open and have no problems.

Try this and see if it show any problem:

#include <Process.au3>
$Drive = "B:"
$sSubst = "subst " & $Drive & " D:\cd_temp" ;" c:\NHS_CFH_DICOM_Images\encryption")
;MsgBox (0, "$sSubst", $sSubst)
;$rc= _RunDOS ($sSubst)
$Result = RunWait(@ComSpec & " /k " & $sSubst, "", @SW_SHOW)
;DriveGetDrive

Thanks.

I think RunWait is indeed the solution - thinking back, I may have had a messagebox making a delay when it ran successfully, which coincided with having the dos box open [to do the /d to undo the substitution].

Also to put some emphasis on one of your statements

ProcessClose() or ProcessWaitClose() could be what you are looking for. The process will be "cmd.exe". The other way is rather nasty and involves putting focus on the Cmd window and using Send("exit") but that is only for dire emergencies and may even require an extra Send() before that to break out of whatever it's doing at the time.
