Question

Using gdiplus.

Asked by: MichaelKatz

I am trying to get full text justification into a vfp report.

I pasted some code but can't seem to find the library "system.vcx". I may have more questions after this is resolved, but at this point I have to find the library to get the report to run

DEFINE CLASS FullJustifyListener AS _ReportListener OF ;
		ADDBS(HOME(1)) + "FFC\_ReportListener.VCX"
	oGDIGraphics = NULL
	DIMENSION aRecords[1]
 
	* Doug Hennig - If ListenerType hasn't already been set, set it based on whether the report
	* is being printed or previewed.
	FUNCTION LOADREPORT
	WITH THIS
		DO CASE
		CASE .LISTENERTYPE <> -1
		CASE .COMMANDCLAUSES.PREVIEW
			.LISTENERTYPE = 1
		CASE .COMMANDCLAUSES.OutputTo = 1
			.LISTENERTYPE = 0
		ENDCASE
	ENDWITH
	DODEFAULT()
	ENDFUNC
 
	* Before we run the report, we need to Make sure that GdiPlusX
	* was initialized, and create a new Graphics object
	*!*	FUNCTION BEFOREREPORT
	*!*	   DODEFAULT()
	*!*	   WITH This
	*!*	   * Check if we already have the "System" object in "_Screen"
	*!*	   IF NOT PEMSTATUS(_Screen,"System",5)
	*!*	      DO LOCFILE("System.App")
	*!*	   ENDIF
 
	*!*	   .oGDIGraphics = _SCREEN.SYSTEM.Drawing.Graphics.New()
	*!*	   .SetFRXDataSession() && switches to the FRX cursor's datasession
	*!*	   DIMENSION .aRecords(RECCOUNT(), 13)
	*!*	   SCAN FOR "<FJ>" $ UPPER(User)
	*!*	      .aRecords(RECNO(), 13) = "FJ"
	*!*	   ENDSCAN
	*!*	   .ResetDataSession() && restores the datasession ID to the one the listener is in
	*!*	   ENDWITH
	*!*	ENDFUNC
 
 
	FUNCTION BEFOREREPORT
	DODEFAULT()
	WITH THIS
		* Check if we already have the "System" object in "_Screen"
		IF NOT PEMSTATUS(_SCREEN,"System",5)
		DO LOCFILE("System.App")
*			_SCREEN.ADDPROPERTY("System", NEWOBJECT("xfcSystem", LOCFILE("system.vcx")))
		ENDIF
		
		.oGDIGraphics = _SCREEN.SYSTEM.Drawing.Graphics.New()
		.SetFRXDataSession()
		DIMENSION .aRecords[reccount(), 13]
		SCAN FOR "<FJ>" $ UPPER(USER)
			.aRecords[recno(), 13] = "FJ"
		ENDSCAN
		.ResetDataSession()
	ENDWITH
	ENDFUNC

There's a _system.vcx as the base classlib of several FFC (foxpro foundation classes) in HOME()+"FFC", where you also find _reportlistener.vcx. As your code actually does a LOCFILE("system.vcx") I don't know, maybe simply a typo and what's needed is in fact _system.vcx?

Bye, Olaf.

 

by: pcelbaPosted on 2009-10-19 at 10:28:40ID: 25607161

System.vcx is required by
_SCREEN.ADDPROPERTY("System", NEWOBJECT("xfcSystem", LOCFILE("system.vcx")))

BUT if you omit the ", LOCFILE("system.vcx")" then it will work because the CLASS xfcSystem is already defined in system.prg (look for "DEFINE CLASS xfcSystem AS xfcNamespace") and you may find it in source downloaded together with GDIPlusX.ZIP

I copied both libraries to the app folder and still get an error

---------------------------
Error
---------------------------
Alias: CLDATA
Error number: 1733
Error message: Class definition XFCSYSTEM is not found.
Line of code with error: _SCREEN.ADDPROPERTY("System", NEWOBJECT("xfcSystem", LOCFILE("_system.vcx")))
Program with error: beforereport
Line number of error: 56

I don't think I have the right library.

Michael

Sorry, I forgot to tell, system.prg is included in system.app

 

by: tusharkanvindePosted on 2009-10-19 at 10:42:54ID: 25607290

In the newer versions of GDI Plus, the classes have been moved from system.vcx to system.prg. So system.vcx no longer exists.

I have

      _screen.NewObject('system','xfcSystem','system.fxp')

where I use GDIPlus.

 

by: tusharkanvindePosted on 2009-10-19 at 10:49:04ID: 25607344

I think you will need

_screen.NewObject('system','xfcSystem','system.app')

instead.

 

by: pcelbaPosted on 2009-10-19 at 10:57:26ID: 25607424

I would say you nedd NOTHING from above after issuing

DO system.app

command.

Above command will create and initialize the _screen.System  property.

Your code already does it and it does not need system.vcx (this line is commented out already).

 

by: pcelbaPosted on 2009-10-19 at 10:59:42ID: 25607450

So, the question is: Why do you need system.vcx? Is it used somewhere else?

 

by: pcelbaPosted on 2009-10-19 at 11:00:52ID: 25607462

This just shows how often and heavily are we using GDIPlusX... :-)

 

by: tusharkanvindePosted on 2009-10-19 at 11:11:57ID: 25607579

PCelba is correct. The VCX line is commented out and you don't need it. Just a DO SYSTEM.APP is enough.

 

by: Olaf_DoschkePosted on 2009-10-19 at 14:05:58ID: 25609047

Sorry Michael,

I didn't realise this is about gdiplusX. Thought it was using both FFC reportlisteners and FFC gdiplus class, but Doug Hennig is mixing FFC reportlisteners with GDIPlusX. That's okay.

So as the others already said you don't really need that, if System object already exists, this code is not needed. Seems it was written for an older version of gdiplusX with no system.app.

Bye, Olaf.

I believe that the FJListener I was using works fine on memo field but no on text/labels.  I will have to live with it in the meantime.
