Problem in errsysw.prg in FWH 10.9

[driessen]

Hello,

Since I updated to FWH 10.9, a GPF occurs when an error occurs.

After analysing the problem, I found out that the GPF occurs in this sentence in ERRSYSW.PRG :

Code: Select all  Expand view

  cErrorLog += "   Hardware memory: " + ;
               cValToChar( Int( nExtMem() / ( 1024 * 1024 ) ) + 1 ) + ;
               " megs" + CRLF
 

In FWH 10.8, this GPF does not occur.

Anyone any idea what is wrong ?

Thank you very much in advance for any help.

Michel,

It seems as there are some random problems with function nExtMem().

The current code for it is:

Code: Select all  Expand view

HB_FUNC( NEXTMEM ) // --> nHardwareMemory
{
   MEMORYSTATUSEX mst;

   mst.dwLength = sizeof( MEMORYSTATUSEX );

   GlobalMemoryStatusEx( &mst );

   hb_retnll( mst.ullAvailPhys );
}

If the GPF persists, then please create a dummy function nExtMem():

function nExtMem()

return 0

Antonio,

Thank you for answer.

Will the problem be solved in FWH 10.10?

Michel,

Could you please modify function nExtMem() this way (it is located in FWH\source\winapi.mem.c) and check if the errors remain ? thanks

Code: Select all  Expand view

HB_FUNC( NEXTMEM ) // --> nHardwareMemory
{
   MEMORYSTATUSEX mst;

   memset( &mst, 0, sizeof( MEMORYSTATUSEX ) );
   mst.dwLength = sizeof( MEMORYSTATUSEX );

   GlobalMemoryStatusEx( &mst );

   hb_retnll( mst.ullAvailPhys );
}

Antonio,

I changed mem.c, like you told me to.

I rebuild my application, but the GPF is still occuring.

But I think that the FWH-libraries have to be rebuild too, or am I wrong?

Unfortunately, I don't know how I have to do that.

But thanks anyway.

Meanwhile I put an asterisk in front of the lines which cause the problem and it's working right now.

Michel,

You could implement that modified function inside a #pragma BEGINDUMP #pragma ENDDUMP of one of your PRGs, so you don't have to rebuild FWH libs. To check that yours is being used simply place a trace into it:

Code: Select all  Expand view

HB_FUNC( NEXTMEM ) // --> nHardwareMemory
{
   MEMORYSTATUSEX mst;

   memset( &mst, 0, sizeof( MEMORYSTATUSEX ) );
   mst.dwLength = sizeof( MEMORYSTATUSEX );

   MessageBox( 0, "mine", "ok", 0 );  / Here !!!

   GlobalMemoryStatusEx( &mst );

   hb_retnll( mst.ullAvailPhys );
}

Antonio,

I tried to do what you told me to do.

I added this source at the end of my first PRG :

Code: Select all  Expand view

#pragma BEGINDUMP

HB_FUNC( NEXTMEM ) // --> nHardwareMemory
{
   MEMORYSTATUSEX mst;

   memset( &mst, 0, sizeof( MEMORYSTATUSEX ) );
   mst.dwLength = sizeof( MEMORYSTATUSEX );

   MessageBox( 0, "mine", "ok", 0 );  / Here !!!

   GlobalMemoryStatusEx( &mst );

   hb_retnll( mst.ullAvailPhys );
}

#pragma ENDDUMP
 

but I got a list of errors while rebuilding :

Undeclared identifier 'MEMORYSTATUSEX"
Syntax error; found 'mst' expecting ';'
Undeclared identifier 'mst'
....

What now?

Thanks.

Michel,

Please add these lines:

#pragma BEGINDUMP

#include <windows.h>
#include <hbapi.h>

...

Antonio,

Problem solved. Thank you very much.

[Antonio Linares]

Michel,

No more GPFs ?

[driessen]

Antonio,

Indeed, no more GPF's. Will the problem be solved in FWH 11.10?

Thanks for your help

[Antonio Linares]

Michel,

Yes, we will include this fix in FWH 11.10
