Check if file is closed
Hi !

I'm looking for a funktion to check if a file is closed.
For example :
I execute in a command shell something like
ping xxx.xxx.xxx.xxx > server.txt

So, it takes a few secondes to get the information and close the file.
Now i want to read the file to check if my server response.
But on my slow notebook it takes too long ...
Now i want to wait till the file is closed.

Does anyone have an idea?

Thanks
Dizzy

Use ExecWait to wait for the command to finish ;)

ExecWait fires my command - but if there are file actions it will not wait till closing my file ... depends on my slow harddrive ;-(

I've got a workaround using a little bit code of "FileSizeNew" (see below) ...
Not the best way (i think) but it works :p


get server answer to file

  ExecWait '$TEMP\runh.exe "$TEMP\serv.bat"'


 loop1:

   IfFileExists "$TEMP\serv.txt" next1 loop1

  next1:

   Push "$TEMP\serv.txt"

    Call FileSizeNew

    Pop$0

    IntCmp$0 250 next1 next1 next2

  next2:

>Functionend


>function FileSizeNew

  Exch$0

  Push$1

  FileOpen$1 $0 "r"

 FileSeek $1 0 END $0

  FileClose$1

  Pop$1

  Exch$0

functionend

Better ideas?

nsExec should soon have the process return value pushed to the stack. It should do the trick, no need writing the output to any file, just check the return value.
