Hi there,

Code:
function GetTheProcessList()
 local T = {}
 local SL=createStringlist()
 getProcesslist(SL)
 for i=0,strings_getCount(SL)-1 do
  T[i] = strings_getString(SL,i)
  print(T[i])   -- Output
 end
 return T
end

GetTheProcessList()


With function above will listing process running in memory.
How to sort output list using table.sort or foreachinorder(table) by PID or processname with ascending sort order?.

Thanks

use pl=getProcessList() and then use lua's for pid,name in pl do ...

Thanks DB

Method 1 : Sorting by pid

Code:
local pl = getProcessList()
local tkeys = {}
for k in pairs(pl) do table.insert(tkeys, k) end
table.sort(tkeys)
for _, k in ipairs(tkeys) do print(k, pl[k]) end

result :
4 System
164 notepad.exe
316 smss.exe
372 nvstreamsvc.exe
444 csrss.exe
448 NvNetworkService.exe
512 taskeng.exe
520 csrss.exe
528 wininit.exe
576 winlogon.exe
624 services.exe
632 lsass.exe
640 lsm.exe
752 svchost.exe
816 nvvsvc.exe
..
..
..
4064 cheatengine-i386.exe



Method 2 : Sorting by process name

Code:
function getKeysSortedByValue(tbl, sortFunction)
  local keys = {}
  for key in pairs(tbl) do
    table.insert(keys, key)
  end
  table.sort(keys, function(a, b)
    return sortFunction(tbl[a], tbl[b])
  end)
  return keys
end

pl = getProcessList()
local sortedKeys = getKeysSortedByValue(pl, function(a, b) return a < b end)
for _, key in ipairs(sortedKeys) do
  print(key, pl[key])
end

result :
3004 AsusSGPlusBTServer.exe
2892 AsusTPCenter.exe
3672 AsusTPHelper.exe
2444 AsusTPLoader.exe
1960 HD-LogRotatorService.exe
2004 HD-UpdaterService.exe
2596 NvBackend.exe
448 NvNetworkService.exe
..
..
..
..
576 winlogon.exe


So, then we use the function above to adding items to a combobox or a listbox for sorted process list.

Regards

If it is for loading Browser processes alike that have many same names instances, it may be better use the form getProcesslist(SL) , since it seems the list preserve the order of process starting. ie. higher index process should be more recently started.

The attached *.lua separated process listing with some filter function and sorting function. For example, instead of sort the process by names, it may be more convenient for the user to filter out those name that's not a target, eg. only keep known browser *.exe named process.

The "order" mention above may be a more useful sorting criteria than by names or by pid number.
Another one may be sort by memory usage of the process, but it may need more work to get this info per pid.
Combine with lesser possible selection (eg. filter by browser names). the user should select the target process more accurately, or your program just select the 1st one list (most recent if by order).

bye~

Code:

function GetTheProcessList()

 local T = {}
 local SL=createStringlist()
 getProcesslist(SL)
 for i=0,strings_getCount(SL)-1 do
  T[i] = strings_getString(SL,i)
 -- print(T[i])   -- Output
 end
 SL = nil

 return T
end




function SortByPID(sender)    ---- table is sender
local PIDsort = {}
  for x = 1, #sender do
   PIDsort[x] = sender[x]
  end

  table.sort(PIDsort)
 
 return PIDsort   --- retunr new table preserving old table
end




function SortByName(sender)   --sorts table by name with incremental PID's

 local A = SortByPID(sender)
 local NameSort = {}
 local FinalSort = {}

    for x = 1,#A do
     NameSort[x] = string.sub(A[x],10)..'-'..string.sub(A[x],0,8)
    end

 table.sort(NameSort)    --- table with names first then PID

    for x=1, #NameSort do            --- FLIP PIDs and Name
    FinalSort[x] = string.sub(NameSort[x],-8).."-"..string.sub(NameSort[x],0,-10)
    end


 A = nil
 NameSort = nil

 return FinalSort
end



function ReverseOrder(sender)
 local RevTable = {}
   
   for x = #sender, 1,-1 do
     RevTable[#RevTable+1] = sender[x]
    end

 return RevTable
end




-----------------------------------------------------------------------------------
------------    Usage Examples ----------------------------------------------------
-----------------------------------------------------------------------------------



PID = GetTheProcessList()      --- A is returned table from GetTheProcessList()

Sort = SortByPID(PID)       ---- call function with sender (A = table)

NamePid = SortByName(GetTheProcessList())

Rev = ReverseOrder(NamePid)



for x = 1,#PID do
print(PID[x])    ---- prints system table
end

for x = 1,#Sort do
print(Sort[x])    ---- prints system table by PIDs
end

for x = 1,#NamePid do
print(NamePid[x])    ---- prints system table by Soted PID's and Name
end


for x = 1,#Rev do
print(Rev[x])    ---- prints table in Reverse Order
end






I know how you are attaching to process's and if you decided to use the pair sort it will makes the rest code required to attach to process become cumbersome.

ALSO your sort by name with pairs method returns

--[[ --- Output unsorted by PID
1180 svchost.exe
1580 svchost.exe
1976 svchost.exe
1164 svchost.exe
1912 svchost.exe
]]

Out of order PID's

Thanks both of you panraven and akumakuja28

What I am trying to do is make a process list which allow user to attach a process by two methods. First method is by double click on a selected process from process list. This is using 'function pidDialog(doPID)' as you known. (Capture)

And second method is allow user to choose specific process from selection process list provide on a combobox. (Capture 2)

panraven, I will try to implementing your selProcReloaded.lua on my script.

akumakuja28, one line missed on your script

Code:
function SortByPID(sender)    ---- table is sender
  for x = 1, #sender do
   PIDsort[x] = sender[x]
  end

  table.sort(PIDsort)
 
 return PIDsort   --- retunr new table preserving old table
end

--- need add table
local PIDsort = {}


Btw, everything work good and I have try to implementing your script on my script too.

Regards
