There are some differences between Harbour and xHarbour.

Harbour hb_compileBuf() is very powerfull as no external Harbour.exe is required. xHarbour should provide it.

Also, as you have seen, __HrbRun() is a little different too. But using it with HRB files from disk, they will behave the same.

[nageswaragunupudi]

In xharbour ,

we can do :

Code: Select all

__HrbRun( <file.hrb> )

// or

cHrb := memoread( "file.hrb" )
pBody := __hrbload( cHrb ) //   __hrbload( "file.hrb" ) also works
                                        //  pBody is pointer variable
__hrbdo ( pBody )

// or we can make a small function
FUNCTION XHRBRUN ( cSource )  // can be file on disk or buffer in memory
RETURN __HrbDo( __HrbLoad( cSource ) ) 

// note: this is from the sourc of ver 99.70
// works with ver 99.71

NageswaraRao,

Better rename cSource as cHRBFileName to avoid confusions, thanks

[nageswaragunupudi]

Yes thanks. I forgot to unload the pointer.

Code: Select all

FUNCTION xHrbRun( cHRBfileNameOrcHRBCode )

LOCAL pHrb

   __HrbRun( pHrb := __HrbLoad( cHRBfileNameOrcHRBCode ) )
   __HrbUnload( pHrb )

RETURN NIL
// Note: arguments support still to be added

The above function can be used for .hrb file on disk or hrb compiled code in memory ( ideal for storing in database and execute retrieved code )

[Rimantas]

My mistake, you can directly execute it from memory too

__HrbRun( MemoRead( "another.hrb" ) )

Thanks for the samples and explanations , Antonio . I'll tried that . Only one question - can we use FWH syntax in this externals prgs ? That's the "another.prg" can contain DIALOG , BUTTONS , GET in FWH syntax ? Also it's one important - will that suport native class ? I'm using xHarbour Bcc ...

With best regards ! Rimantas

Yes thanks. I forgot to unload the pointer.

Code: Select all

FUNCTION xHrbRun( cHRBfileNameOrcHRBCode )

LOCAL pHrb

   __HrbRun( pHrb := __HrbLoad( cHRBfileNameOrcHRBCode ) )
   __HrbUnload( pHrb )

RETURN NIL
// Note: arguments support still to be added

Always get error :

What I'm doing bad ?

Yes

Rimantas,

Please try the test I posted

[Rimantas]

Rimantas,

Please try the test I posted

Thanks Antonio ! Your test is working - simply __HbRun() . Also I tried with __HbRun( MemoRead( cFile ) ) - it return the same error "Corupption detected __HbLoad" . It seems that works only HbRun ...

Many thanks Antonio , it seems that you directed me to true way ...

With best regards ! Rimantas

__HrbRun( MemoRead( "another.hrb" ) )

I'm confused. What is in an .HRB file? Is it simply FW code? If so, then could we just read a PRG? Any PRG?

__HrbRun( MemoRead( "another.prg" ) )

[Antonio Linares]

James,

> What is in an .HRB file?

HRB is a binary file (not ascii) that contains some specific Harbour information (pcode, symbols table).

Its called "Harbour portable file" as theoretically could be executed on any operating system, as it does not include any operating system related info.

[nageswaragunupudi]

Does any one know the equivalent of Harbour's hb_compileBuf() in xHarbour please?

[Antonio Linares]

afaik, it is not implemented in xharbour

[nageswaragunupudi]

Sad. Missing a really powerful and very useful function.
