How do I replace errsysw.prg

[HunterEC]

Guys:

How can I replace the default errsysw.prg (.obj) with a custom one at link time ?

Thank you.

Hunter,

Guys:

How can I replace the default errsysw.prg (.obj) with a custom one at link time ?

Thank you.

Just compile and link the new one. Give it the same filename (errsysw.prg) so the new will replace the old.

Enrico:

I just added this line to the BUILDX.BAT file:

Code: Select all

echo errsysw.obj + >> b32.bc

Here's the section where I added it:

Code: Select all

echo %bcdir%\lib\c0w32.obj + > b32.bc
echo %1.obj, + >> b32.bc
echo %1.exe, + >> b32.bc
echo %1.map, + >> b32.bc
echo errsysw.obj + >> b32.bc
echo %fwh%\lib\Fivehx.lib %fwh%\lib\FiveHC.lib + >> b32.bc

And the ONLY LINE I had changed in ERRSYSW.PRG is this one:

Code: Select all

   n := 2    // we don't disscard any info again !
   while ( n < 74 )

       if ! Empty( ProcName( n ) )
          cErrorLog += "   " + Trim( ProcName( n ) ) + CRLF
--->       if ProcName ( n ) != "NETUSE"   <---  CHANGED LINE
             for j = 1 to ParamCount( n )
                cErrorLog += "     Param " + Str( j, 3 ) + ":    " + ;
                             ValType( GetParam( n, j ) ) + ;
                             "    " + cGetInfo( GetParam( n, j ) ) + CRLF
--->       next   <---  CHANGED LINE
             for j = 1 to LocalCount( n )
                cErrorLog += "     Local " + Str( j, 3 ) + ":    " + ;
                             ValType( GetLocal( n, j ) ) + ;
                             "    " + cGetInfo( GetLocal( n, j ) ) + CRLF
             next
          endif
       endif

       n++
   end
 

On any error (dbf file not found, etc.) the ERRSYSW does not work and the only things that "pops up" is a Windows XP error window:

Code: Select all

appname.exe
appname.exe has encountered a problem and needs to
close. We are sorry for the inconvenience.
 

And then the usual stuff to send the error report to Microsoft, etc.

If I don't link the errsysw.obj, THEN the standard ERRSYSW.PRG works flawlessly and display the standard error. Thank you very much.

Hunter,

Enrico:

I just added this line to the BUILDX.BAT file:

echo errsysw.obj + >> b32.bc

Did you compile errsysw.prg?

And the ONLY LINE I had changed in ERRSYSW.PRG is this one:

There is something strange: IF/NEXT?

On any error (dbf file not found, etc.) the ERRSYSW does not work and the only things that "pops up" is a Windows XP error

Try adding a MsgInfo(), just to be sure that your errsysw.prg is correctly compiled and linked.

Enrico:

Thank you for your support. I did compile the ERRSYSW.PRG file. I followed your suggestion to put some MSGINFO() in place to find out if the changes were being linked, and they are. I find out that ERRSYSW.PRG fails at this particular point:

Code: Select all

   // Warning!!! Keep here this code !!! Or we will be consuming GDI as
   // we don't generate the error but we were generating the bitmap

   hLogo = FWBitMap()
 

When the FWBitMap() function / procedure is called the program fails and Windows XP error management kicks in.
If I comment that line ERRSYSW.PRG works FLAWLESSLY.

Code: Select all

   // Warning!!! Keep here this code !!! Or we will be consuming GDI as
   // we don't generate the error but we were generating the bitmap

//   hLogo = FWBitMap()
 

Any clues ?


Thank you.

No, sorry.

Thank you anyways.

In our errsysw, I still have the hlogo = FWBitMap() line, but have removed other references except the destroyobject line.

Maybe try to remove all references to hlogo to see if the errsysw works.

Best regards,

Pete
