Sometimes it may be useful to export a list of all 4D processes. This can be used for debugging, troubleshooting, or simply for logging purporses.

The follwing method can be used to export such a list in Tab delimited format. Note that the "SEND PACKET" lines of code are very long and break over multiple lines in the example below:

C_TIME($theDoc)
C_TEXT(procName)
C_LONGINT($a;taskCount_l;procState;procTime;uniqueID;origin)
C_BOOLEAN(procVisible)

taskCount_l:=Count tasks
$theDoc:=Create document("the_processes.txt")

` SEND PACKET line breaks, caution when copying and pasting code
SEND PACKET($theDoc;"ID"+Char(Tab )+"NAME"+Char(Tab )+"STATE"+Char(Tab )+"TIME"+Char(Tab )+"VISIBLE"+Char(Tab )+"UID"+Char(Tab )+"ORIGIN"+Char(Carriage return ))

For ($a;1;taskCount_l)
    PROCESS PROPERTIES($a;procName;procState;procTime;procVisible;uniqueID;origin)

    ` SEND PACKET line breaks, caution when copying and pasting code
    SEND PACKET($theDoc;String($a)+Char(Tab)+procName+Char(Tab)+String(procState)+Char(Tab )+String(procTime)+Char(Tab )+String(procVisible)+Char(Tab)+String(uniqueID)+Char(Tab)+String(origin)+Char(Carriage return ))

End for

CLOSE DOCUMENT($theDoc)


The code simply creats a text document to store the process data and then runs through a list of processes, obtained via the Count tasks and PROCESS PROPERTIES commands. Each process's data is written to the file.

You can extend the value of this method by adding a small subroutine for the procState and the origin parameters where instead of showing the numerical value it can show the Constant. For instance, if the procState is -1 your log could read Aborted instead.
