Job A does not wait for Job B to complete:

Job A (VBS):
Sub Main
JALScript.Execute "JobRun ""215"""
Msgbox "hello",64, "header"
End Sub

Job B (JAL):
dim bol_number, string
dim File_Handle, number
FileReadLine( "D:\\24x7\\BCCTemp.txt", 1, BOL_Number )
Wait( 1 )
messagebox( BOL_Number )
FileOpen( "D:\24x7\BCCTemp.txt", "LineMode", "Write", False, File_Handle)
FileWrite( File_Handle, "test" )
FileClose( File_Handle )
FileReadLine( "D:\\24x7\\BCCTemp.txt", 1, BOL_Number )
Wait( 1 )
messagebox( BOL_Number )

: If you want job A to wait for job B to complete use either

: JALScript.Execute("JobRun [job id]")

: or

: Set shell = CreateObject("WScript.Shell")
: shell.Run "24x7.exe /JOB [job id]", 0, 1

: If you do not want job A to wait then simply do

: Set shell = CreateObject("WScript.Shell")
: shell.Run "24x7.exe /JOB [job id]", 0, 0

Are these jobs setup to run synchronous or asynchronous?

: Job A does not wait for Job B to complete: Job A (VBS): Sub Main
: JALScript.Execute "JobRun ""215"""
: Msgbox "hello",64, "header"
: End Sub

Job A won't run unless it's asynchronous (otherwise 24x7 locks up).
Job B I tried both ways and Job A still finishes before Job B.

Please upgrade to 3.4.9 this will fix the hanging issue. For more info please see "Cross-Language Calls Hang... Sometimes" message thread for more info http://www.softtreetech.com/cgi_bin/config.cgi?read=3908

Please see my response in the previous thread.
