Save memory vars to text file

[Jeff Barnes]

Hi All,


Is there a way to store ALL memory var's to a text file?

I've tried SAVE TO but it does not give me ALL var's.


Thanks,

Jeff

From ng :

SAVE copies public and private memory variables visible within the
current procedure or user-defined function to a memory (.mem) file.
Arrays and local and static variables, however, cannot be SAVEd. When
variables are SAVEd, they are copied without any reference to scope.
Variables hidden by PRIVATE or LOCAL declarations are not SAVEd.


However , in errorsysw.prg you have an example from how local variables from a procedure are retrieved

Actually, what I am looking for is something that will store the memoy in a format similar to:

cTextValue = "This is the text value"
nNumberValue = 123456

etc...

I am looking to add some troubleshooting / revocery options to one of my apps but I need to know what is stored in memory.


Thanks,
Jeff

I found functions in the manual called:

LogStatics() and Scan()

It looks like these might help me do what I want but I can not get either of them to work.

Friend

You can use .INI files to store variables names end data.

MyINI.INI

Code: Select all

[VARIABLES]
cTextValue="This is the text value" 
nNumberValue=123456 

Use this example:

Code: Select all

// Sample showing how to use INI files with FiveWin

#include "FiveWin.ch"

//----------------------------------------------------------------------------//

function Main()

   local oWnd, oIni, oBar
   local cTitle, cMsg, cLogo
   local nRow  := 3, nCol := 5, nWidth := 50, nHeight := 50
   local cBtn1 := "", cBtn2 := ""

   INI oIni FILE ".\MyApp.ini"
      GET cTitle  SECTION "main" ENTRY "Title"   OF oIni DEFAULT "FiveWin App"
      GET cMsg    SECTION "main" ENTRY "Message" OF oIni DEFAULT "Main message"

      GET cLogo   SECTION "Logo" ENTRY "File"    OF oIni
      GET nRow    SECTION "Logo" ENTRY "Row"     OF oIni
      GET nCol    SECTION "Logo" ENTRY "Col"     OF oIni
      GET nWidth  SECTION "Logo" ENTRY "Width"   OF oIni
      GET nHeight SECTION "Logo" ENTRY "Height"  OF oIni

      GET cBtn1   SECTION "ButtonBar" ENTRY "Button1" OF oIni
      GET cBtn2   SECTION "ButtonBar" ENTRY "Button2" OF oIni
   ENDINI

   DEFINE WINDOW oWnd FROM 1, 5 TO 20, 60 ;
      TITLE cTitle

   DEFINE BUTTONBAR oBar OF oWnd

   if ! Empty( cBtn1 )
      DEFINE BUTTON OF oBar FILE cBtn1
   endif
   if ! Empty( cBtn2 )
      DEFINE BUTTON OF oBar FILE cBtn2
   endif

   SET MESSAGE OF oWnd TO cMsg

   @ nRow, nCol BITMAP FILE cLogo SIZE nWidth, nHeight OF oWnd

   ACTIVATE WINDOW oWnd

return nil

//----------------------------------------------------------------------------//

I am looking for a function that will give me ALL my mem vars ... depending where my user is in the prtogram the vars will have different names so the .ini solution will not work for me.


Thanks anyway.

They are for STATIC variables only.

Hi Enrico,

I realize that they are for Static vars only but I still can not get them to work.

When I compile I get:

Error: Unresolved external '_HB_FUN_LOGSTATIC'

If I try to compile the \FWH\Source\Functions\Static.prg I get:

Error: Unresolved external '_HB_FUN_STATIC'

I can't seem to win on this one.

This is a working sample:

Code: Select all

#include "Fivewin.ch"


STATIC TEST1 := "This is a test 1"
STATIC TEST2 := "This is a test 2"
STATIC TEST3 := "This is a test 3"


FUNCTION MAIN()

    LOCAL i

    ? NSTATICS(), HB_DBG_VMVARSLEN()

    FOR  i = 1 TO 3
        ? HB_DBG_VMVARSGET( i )
    NEXT

    RETURN NIL

Enrico,

This gets me a bit closer but how do you get the var's name?

Thanks again,

Jeff

[Enrico Maria Giordano]

I'm not sure you can get the name of a STATIC var. You better ask to xHarbour newsgroup. Meanwhile, this is a better sample:

Code: Select all

#include "Fivewin.ch"


STATIC TEST1 := "This is a test 1"
STATIC TEST2 := "This is a test 2"
STATIC TEST3 := "This is a test 3"


FUNCTION MAIN()

    LOCAL aStatics := __VMVARSLIST()

    LOCAL i

    ? NSTATICS(), __VMVARSLEN(), LEN( aStatics )

    FOR  i = 1 TO 3
        ? __VMVARSGET( i ), aStatics[ i ]
    NEXT

    RETURN NIL

Jeff,

You can only get the static variables names (same for locals) if the PRG has been compiled using /b (debug info). Without /b the names are lost (not used at all)
