Migrating to Harbour

[Enrico Maria Giordano]

Maurizio,

Ciao Enrico

Did you read c:\Harbour\doc\xhb-diff.txt ?

Maurizio

Yes, I read it. What's your point?

I have migrated a while ago to Harbour and Msvc , i use a lot of try/catch like below and i have no problems with it, i don't see the point.

TRY
oExcel := CREATEOBJECT( "Excel.Application" )
CATCH
MSGSTOP("L'Application Microsoft Excel n'est pas installée sur cet Ordinateur !" )
RETURN NIL
END

PS : I use Uestudio, in case it can help i join the make file

Richard,

I have migrated a while ago to Harbour and Msvc , i use a lot of try/catch like below and i have no problems with it, i don't see the point.

TRY
oExcel := CREATEOBJECT( "Excel.Application" )
CATCH
MSGSTOP("L'Application Microsoft Excel n'est pas installée sur cet Ordinateur !" )
RETURN NIL
END

Harbour doesn't support TRY/CATCH/END structure.

PS : I use Uestudio, in case it can help i join the make file

I can't see anything related to TRY/CATCH/END in your configuration file. Please, can you address me to the right section of the file?

I have this in my fivewin.ch (fwh 13.05)

I have this in my fivewin.ch (fwh 13.05)

Ok, but I was speaking about console, pure Harbour, samples, no FWH involved.

The hbcompat.ch file maps TRY/CATCH to harbour's native BEGIN SEQUENCE/END SEQUENCE implementation, it isn't adding anything feature wise. I avoid using hbcompat.ch at all, I think I only have one .prg where I have to use it. I did find it useful to identify native harbour function names and calls. I used xhb.lib when I first began using harbour until I figured out its lay of the land. I stopped using it altogether, up until I introduced FiveWin to my environment, at which point I had to introduce in in the fwh.hbm module I shared. I haven't tried without it lately, that may have changed.

I suggest some caution in this regard as the fivewin installer includes a copy of hbcompat.ch, presumably direct from harbour source, but it is easy to wind up with a .ch file in the fivewin include directory that is not identical to what is current in harbour. I am careful to search for includes in harbour\include first, before fivewin\include, but even that has bitten me when harbour has a header with a conflicting name but different implementation is used in fivewin. My most recent favorite was dll.ch, which doesn't exist in harbour directly, but does exist in harbour\contribs\hbxpp. I spent way too many hours, and consumed a bit on Antonio's time. tracking that one down. I am NOT picking on fivewin here, the caution exists with any third party components, and it is not always immediately obvious that the condition exists.

I respect your decision to stick with batch files, I respect even more not wanting to disrupt a build system that works for you. I stuck with batch and mak files for many years, but once I realized what could be done with the harbour make system the reason to change was compelling, at least it was for me.

I don't need an external tool for compile. I develop it myself.

Robb:

I've been following your post in this thread. I'm beggining to move from xHarbour / Borland C to Harbour / MSVC 2010. Can you post a simple example of a make file that checks and compile 2 PRGs ? Thank you.

[Enrico Maria Giordano]

The next problem is CurDrive(). It's undefined...

EMG

[Enrico Maria Giordano]

Ok, it has been changed to Hb_CurDrive()...

EMG

[Enrico Maria Giordano]

Next problem: OLEDEFAULTARG(). I didn't find a replacement...

I already tried to remove it.

I use this in my main program

#ifndef __XHARBOUR__
FUNCTION DbSkipper( n ) ; RETURN __DbSkipper( n )
FUNCTION DbPack() ; RETURN __DbPack()
FUNCTION DbZap() ; RETURN hb_DbZap()
FUNCTION CurDrive( x ) ; RETURN hb_CurDrive( x )
#EndIf

Richard,

Enrico

I use this in my main program

#ifndef __XHARBOUR__
FUNCTION DbSkipper( n ) ; RETURN __DbSkipper( n )
FUNCTION DbPack() ; RETURN __DbPack()
FUNCTION DbZap() ; RETURN hb_DbZap()
FUNCTION CurDrive( x ) ; RETURN hb_CurDrive( x )
#EndIf

Thank you. And what about OleDefaultArg(). This is a sample:

Code: Select all  Expand view

FUNCTION MAIN()

    LOCAL oExcel := CREATEOBJECT( "Excel.Application" )

    LOCAL cXls := "e:\harbour\mytest.xls"

    oExcel:WorkBooks:Open( cXls, , , OLEDEFAULTARG(), , , , OLEDEFAULTARG(), , , .T., , .T. )

    oExcel:Visible = .T.

    RETURN NIL

Enrico

OleDefaultArg()

is a shortcut to:

VTWrapper( VT_ERROR, DISP_E_PARAMNOTFOUND )

Here is the MSDN doc:

If an optional argument to an Automation method is left blank, do not pass a
VARIANT of type VT_EMPTY. Instead, pass a VARIANT of type VT_ERROR with a
value of DISP_E_PARAMNOTFOUND.

http://msdn.microsoft.com/en-us/library/ms221627.aspx

There is a lot on it on google, but for my own curiosity , is this function working with xharbour ? Not sure from what i read, i may be wrong.

HunterEC,

Yes, please post, I will help with what I can. But I'd prefer we don't hijack Enrico's thread, would you please start another regarding build options for harbour. I suspect there will be many responses, I don't assert that my is any any better than anybody else's, but once I got where I am I could stop worrying with how I was going get something to build and focus on the new code I wish to write. I made several aborted attempts at the transition from xharbour to harbour, and I had an equally high number of aborted attempts to transition from Visual xHarbour to FWH. Those already comfortably at home with FWH probably don't have much interest in this, but for those I presume are attempting what I attempted and not only accomplished, but ended up with something beyond what I had expected. In retrospect it has been a very worthwhile effort.

I do wish to make a specific note here. I speak no ill of xHarbour, I hold xHarbour in the highest regard. It was a marvelous discovery that bridged a wide gap between Clipper and the modern world. I actively use it, it was the product that removed Clipper from my desktop, and continue to have several apps that have been running since their original releases from many years ago, and will continue to run fine into the foreseeable future, they are absolutely rock solid. But there were some specific things xHarbour wasn't going to deliver, or at least not in the time frame I needed a solution to some very specific problems.
