create a function with Tdatabase | Silvio,
Class TDataBase has a destructor method, so when the object gets out of scope then it gets called
change local oDbf into static oDbf (or keep it in an array) so the object is not destroyed |
create a function with Tdatabase | [quote:28verw0u] oDbf := TDatabase():Open(,cAlias)
[/quote:28verw0u]
This syntax is wrong. The DBF is already open.
Correct:

create a function with Tdatabase | thanks |
create a function with Tdatabase | Sivio,
Maybe you didn't know that CDXs have always had the option to open all the indexes automatically when the DBF is opened. And as I understand it, NTXs can now do that also.
REQUEST DBFCDX
rddsetdefault( "DBFCDX" )
SET EXCLUSIVE OFF
SET(_SET_AUTOPEN, .T. ) |

yes I knew it but it happens that in my application there is a function that does not have to load the indexes or in one of the functions that I have seen that does not load them all
As you well know in my old applications made for my school I had problems because sometimes the indexes were missing,
so not checking them first when opening the application seems to me a stretch because I am always afraid of not finding them in that folder |

Hmm, I always open the indexes whether they are used or not. This simplifies coding doesn't have a downside that I can think of.
If you are using database objects, in order to not open the indexes sometimes, it would mean you would have to pass a parameter and when looking at the code you could never tell if the indexes were open or not.
Is there a reason you need them to NOT have the indexes open? |

create a harbour dll containing functions to be executed | That works fine, Thank you Antonio.
One more item - we have the need to pass values back from the DLL to the calling EXE. Is this possible? Is pass by reference "@" a way to modify the value in the DLL and return to the EXE? Do you have to have the same number of parms for each function in the DLL? |
create a harbour dll containing functions to be executed | Perry,
> we have the need to pass values back from the DLL to the calling EXE. Is this possible ?
Yes. What types of values do you need to pass back ? character, number, etc ? We need to know their types in advance.
> Is pass by reference "@" a way to modify the value in the DLL and return to the EXE ?
We can implement it in the function HBDLLENTRY() itself
> Do you have to have the same number of parms for each function in the DLL?
You can implement several functions for each number of params to pass:
void pascal __export HBDLLENTRY1( char * cProcName, PHB_ITEM pParam1 )
{
hb_itemDoC( cProcName, 1, pParam1 );
}
void pascal __export HBDLLENTRY2( char * cProcName, PHB_ITEM pParam1, PHB_ITEM pParam2 )
{
hb_itemDoC( cProcName, 2, pParam1, pParam2 );
}
etc. |

if( HB_ISBYREF( pParam1 ) )
hb_itemPutC( pParam1, hb_retc( -1 ) ); // -1 mean the value returned from cProcName
} |
create a harbour dll containing functions to be executed | Antonio, Thank you for the info - much appreciated.
Regarding passing parameters -
> You can implement several functions for each number of params to pass:
does each parm have to be the same data type in all functions?
Also, I am looking at the samples in FWH64 v1605 and the buildhd.bat looks like a 32 bit build for borland - is there a bat to build a 64bit dll? |
create a harbour dll containing functions to be executed | Perry,
> does each parm have to be the same data type in all functions?
They have to be Harbour "items", thats why you need to use the function ItemNew():

We have not created it yet. I am going to try to create it
Please keep in mind that if you use a 64 bits DLL then you must use a 64 bits EXE to call it |

We provide several examples with FWH:

But I am afraid that you may experience compatibility problems.
We recommend you to upgrade to FWH 8.12 and current xHarbour provided by FiveTech, in order to be able to build and test our same examples, so we can provide you the proper tech support. |

Those examples work with both Harbour and xHarbour.
maindllp.obj is not automatically created by Harbour/xHarbour makefiles, so you have to create it manually from Harbour/xHarbour source\vm\maindllp.c
Here you have maindllp.obj already created for Harbour:

create a pcode dll | Don,
Based on your comments it seems to me that you are talking about a C DLL instead of a pcode DLL.
A pcode DLL is created using PRG code and it uses the EXE "virtual machine". They are small DLLs that just contain "pcode" and need the "virtual machine" from the EXE, to execute the pcode.
A C DLL is created using C code (usually) and its C code is called from the EXE. It does not need the EXE "virtual machine" at all.
I recommend you this document reading as it explains the different kind of DLLs that can be managed with Harbour/xHarbour:

Windows 32-bit DLLs with Harbour code
=====================================
Programs created with Clipper or Harbour are traditionally a
monolithic EXE containing all executable code. This includes
the Virtual Machine (VM) and the RunTime Library (RTL) as well as
your own code. Running under Windows (Win32) with Harbour, you
can now also create and use Windows DLLs that contain PRG code.
Harbour supports Win32 DLLs in 3 ways.
1) Self-contained DLLs containing functions from any platform.
(These are not what we call a "Harbour.dll", although they may
be named that. The DLL entry points are different.)
These have the VM/RTL inside them and can be used by any other
Windows program. You can create a .lib for static linking,
or use GetProcAddress as in any standard Win32 DLL.
Calling Harbour/Prg functions directly is limited to
those that take no parameters unless you include C functions
in the DLL that take parameters and then call the PRG-level
code.
To do static linking, do this to create the .lib:
implib harbour.lib harbour.dll
For the Borland C platform, use that library and import32.lib
and cw32.lib from Borland, and you are ready to go.
See contrib\delphi\hbdll for an example of a Delphi program that can
use all of Harbour's functionality by accessing a self-contained DLL.
BLD_SDLL.BAT is used there to create the DLL.
2) PCode EXEs using a Harbour.dll
A Harbour.dll is designed to be called from a Harbour app.
A pcode EXE is a small Harbour executable that does not contain the
VM/RTL. To execute its functions, it must load and access a
Harbour.dll.
If you want dynamic linking, then use this to execute a Harbour
dynamically loaded pcode DLL function or procedure:
HB_DllDo( <cFuncName> [,<params...>] ) --> [<uResult>]
This lets you have all your common code in a DLL, and have lots
of small EXEs that use it. Realize however that, even though this
may be a nice way to manage your code, each EXE may
load its own image of the Harbour.dll into memory at runtime.
In terms of Windows memory, there may not be a benefit to using pcode
EXEs over monolithic EXEs. But it may be a worthwhile maintenance
benefit to have lots of replaceable small exes.
3) PCode DLLs used from traditional EXEs
A pcode DLL does not contain the VM/RTL.
It is a library of Harbour-compiled PRG code that uses the VM/RTL
of the EXE that calls it. This has the benefit of having
replaceable modules in DLLs that don't necessarily require updating
your EXE.
The following is clipped from a msg by Antonio Linares to the Harbour
developer list explaining some of the details:
Please notice that there are three different Windows DLL entry points:
+ source/vm/
* maindll.c Windows self-contained DLL entry point
* maindllh.c Windows Harbour DLL entry point (harbour.dll)
* maindllp.c Windows pcode DLL entry point and VM/RTL routing functions
> * maindll.c Windows self-contained DLL entry point
To produce Harbour code, as DLLs, that may be used
from other programming languages applications (as VB,
Delphi, C++, etc...)
> * maindllh.c Windows Harbour DLL entry point (harbour.dll)
To produce Harbour.dll, to be just used from small pcode Harbour EXEs
> * maindllp.c Windows pcode DLL entry point and VM/RTL routing
To produce small pcode DLLs, to be used just from Harbour EXE apps.
maindllp.c is the entry point for the Harbour pcode DLLs. pcode DLLs
are quite small DLLs, that just contain pcode and/or C (using extend
api) functions.
mainwin.c is the entry point for Windows EXEs, not for DLLs.
You may use maindll.c, maindllh.c or maindllp.c based on
your needs.
If you are looking to build a Harbour.dll, then you must use
maindllh.c

create a pcode dll | Don,
The question is:
Are you using a third party DLL that can be used from any programming language ? This uses to be a C DLL.
If this is the case, then keep in mind that the C language knows "nothing" about the Harbour/xHarbour items structure. You can just supply C types to the DLL, so you have to convert the Harbour/xHarbour items values to C types, in order to manage them from the DLL.
Have you created the DLL youself using C language ?
Or, have you used harbour.exe to create the DLL ? |

create a pcode dll | Antoio,
Thank you for your feedback.
We are wanting to create an executable dll using prg code. We do not have much C coding experience.
Sounds like the pcode dll is the way to go. We are currently looking at our options to determine the best way to implement custom coding without having to make a new exe.
I am assuming since you did not answer the "pass array question" - it is not possible.
Please advise.
Once again your assistance is greatly appreciated. |

> I am assuming since you did not answer the "pass array question" - it is not possible.
It is perfectly possible <!-- s:-) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":-)" title="Smile" /><!-- s:-) -->
Being a pcode DLL you can supply Harbour/xHarbour items to it. No limitations.
Please show how you are coding your DLL or an example, so we can point you in the right way. thanks |
create a pcode dll | Antonio,
Below is a sample calling prg:
[code:2boqunhf]
#include "FiveWin.ch"
function Main()
local cString := "Hello world!"
local cString2 := "ABC or 123?"
local LPARM := .T., retarr := {}, passparm := {}
local NPARM := 998877
local DPARM := DATE()
DOPROC( "MAIN" )
aadd(passparm, {cstring, cstring2, nparm, lparm, dparm } )
retarr := DOPROC( "ONEPARAM", @passparm )
MsgInfo( "mydll returned OK to myEXE" )
return nil
DLL FUNCTION DOPROC( cProc AS LPSTR, aparm AS ???? ) AS LONG PASCAL LIB "MYDLL.dll"
[/code:2boqunhf]
What we would like to do is call the dll with an array of parameters. This array may contain various data types.
We would like to get back an array contining various data items as needed. Also, is it possible to change the contents of the original passed array and see the results in the calling prg?
Once again your assistance is greatly appreciated. |

If yes, then you are calling a C function and you can not supply a Harbour item to it.
Please review the use of HBDLLENTRY...() in that same post. You can supply a Harbour item to those functions, even if they are arrays <!-- s:-) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":-)" title="Smile" /><!-- s:-) --> |

some files.txt are very very big
how I can make to have a show text type : " Load level2.txt in n seconds"
I try with a timer but it not run good |
create an arra from txt file | Silvio,
It will be much faster the way you did it--loading the entire file into memory then parsing it, rather than reading each line from the disk.
Your coding mistake is here:
nLinea :=MLCOUNT(cTexto)
Should be:
nLinea :=MLCOUNT(cTexto, 81) // was missing the line length
I would also suggest setting cTexto to nil right after you are done parsing it so the memory will be recovered. |

create an arra from txt file | [quote:2r7o63bc]FOpen()
Opens a file on the operating system level.
Syntax
FOpen( <cFileName>, [<nMode>]) --> nFileHandle
Arguments
<cFilename>
This is a character string holding the name of the file to open. It must include path and file extension. If the path is omitted from <cFileName>, the file is searched in the current directory.
<nMode>
A numeric value specifying the open mode and access rights for the file. #define constants from the FILEIO.CH file can be used for <nMode> as listed in the table below: File open modes Constant Value Description
FO_READ *) 0 Open file for reading
FO_WRITE 1 Open file for writing
FO_READWRITE 2 Open file for reading and writing
*) default
Constants that define the access or file sharing rights can be added to an FO_* constant. They specify how file access is granted to other applications in a network environment.
File sharing modes Constant Value Description
FO_COMPAT *) 0 Compatibility mode
FO_EXCLUSIVE 16 Exclusive use
FO_DENYWRITE 32 Prevent other applications from writing
FO_DENYREAD 48 Prevent other applications from reading
FO_DENYNONE 64 Allow others to read or write
FO_SHARED 64 Same as FO_DENYNONE
*) default
[/quote:2r7o63bc]
[quote:2r7o63bc]FRead()
Reads characters from a binary file into a memory variable.
Syntax
FRead( <nFileHandle>, ;
@<cBuffer> , ;
<nBytes> , ;
[<nOffset>] ) --> nBytesRead
Arguments
<nFileHandle>
This is a numeric file handle returned from function FOpen() or FCreate().
@<cBuffer>
A memory variable holding a character string must be passed by reference to FRead(). It must have at least <nBytes> characters.
<nBytes>
This is a numeric value specifying the number of bytes to transfer from the file into the memory variable <cBuffer>, beginning at the current file pointer position.
<nOffset>
This is a numeric value specifying the number of bytes to skip at the beginning of <cBuffer> where the result is copied to. This allows to copy the data from the file into the middle of a string buffer. The default value is zero. Note that the sum of <nBytes>+<nOffset> must be smaller than or equal Len(<cBuffer>).

create and use an index for a set of records | Marco,
The simplest solution would be to move all the record data into the array and then browse the array.
The next simplest would be to create a database class that has a modified skip() method that uses the array as an index. The set the oBrw:bSkip codeblock to use this database skip method.
The most complicated way would be to write functions to work with standard DBF commands that use the array as an index.

James |
create and use an index for a set of records | Marco,
The INDEX command has a clause CUSTOM :
CUSTOM specifies that a custom built order will be created for RDDs
that support them. A custom built order is initially empty, giving you
complete control over order maintenance. The system does not
automatically add and delete keys from a custom built order. Instead,
you explicitly add and delete keys using ORDKEYADD() and ORDKEYDEL().
This capability is excellent for generating pick lists of specific
records and other custom applications.
I never used it , but i suppose you have to

create and use an index for a set of records | [quote:5evhg3gn]The INDEX command has a clause CUSTOM :[/quote:5evhg3gn]
This is the best way to deal with a hand-picked set of records. Along with CUSTOM clause, also if we use TEMPORARY ( or MEMORY ) clause, the index is created locally in the memory or temporary space ( depending on RDD ) and is even faster and is automatically erased when the table is closed. This is what I do in my programs where this is necessary.
Incidentally, if the only intention is to browse the record numbers in an array, xbrowse provides even much simpler way to do this, even without creating any index, custom or otherwise.
Use the normal syntax for creating xbrowse for the DBF and add the clause ROWS aRecArray.
Only the record numbers in the aRecArray are browsed.
Example:
[code=fw:5evhg3gn]<div class="fw" id="{CB}" style="font-family: monospace;"><br />@ <span style="color: #000000;">0</span>,<span style="color: #000000;">0</span> <span style="color: #0000ff;">XBROWSE</span> oBrw <span style="color: #0000ff;">OF</span> oWnd AUTCOLS <span style="color: #0000ff;">ALIAS</span> <span style="color: #ff0000;">"CUSTOMER"</span> ROWS <span style="color: #000000;">{</span> <span style="color: #000000;">22</span>, <span style="color: #000000;">44</span>, <span style="color: #000000;">66</span> <span style="color: #000000;">}</span><br /> </div>[/code:5evhg3gn] |
create and use an index for a set of records | Everything comes from the fact that a function like this at_search() free searches in a table is very much faster than traditional methods.
The function returns an array containing the records that I find the string passed
as parameter.
I put this function in a application that run in a server (search32.exe) in polling mode.
Result of every request from clients is an index creation or an Array containing matching record.

create and use an index for a set of records | Is to do a search in a field
specific database?
Thank
Dorneles |
create and use an index for a set of records | No this is a wild search in all fields of database.
For instance if You considere cutomer.dbf from fwh\samples change Main function on this way
even if the table is not the best example to appreciate the potential of this function.
Customer table is too little.
I search customer name "Tom" that live in a "Street"
aRecord := at_search( "customer", "Tom", "Street" )
Please try this function in a your big big table
Thanks
Marco

create group on report class | Hi Friends
I have coded one report with two groups (using the class report)
Its is possible to create an third group at runtime
and the same time can destroy it before the end of the report?
Thanks in advance! |
create group on report class | If the reason you want to do this is because you only want to use the third group for some versions of the report, you could just define the third group with a conditional.
IF ...
GROUP ON ...
ENDIF

James |

create mind blowing ai art in 5 minutes for free | [url:2zxxkftz]https://medium.com/codex/how-i-create-mind-blowing-ai-art-in-5-minutes-for-free-7456e778c543[/url:2zxxkftz] |
create object y Ocx | Estimados...
Tengo un OCX de 32 bits que resgistre sin problemas en windows 64 bits
Try
xCtrl:=CreateObject(OCXSAM350.Ocxsam350Ctrl.1)
Catch
MsgAlert("Error de carga de controlador")
Return Nil
End
MsgAlert(ValType(xCtrl)) // Devuelve "O", correcto
// Aqui Todo Correcto
MsgAlert(xCtrl:Fecha) //-> WinOle 1007 error de argumento
xCtrl:AboutVox() //-> WinOle 1009 No exported Method
Segun Manuales los variables son FECHA,HORA, ESTADO....
Funciones serian, INIT, FINI, ABOUTBOX....
Si reviso su nombre en el editor de registro, esta bien, si reviso sus variables y funciones con OleView y OleBrow, hay coincidencia en nombres de variables y funciones, o sea todo correcto....
Y aqui estoy sin pillarle la vuelta, Cualquier consejo, ayuda sera bienvenida..
Gracias

create object y Ocx | Prueba con "Date" en vez de "Fecha"
Escribiste AboutBox() con "v", o es al escribirlo en tu mensaje ? |
create object y Ocx | Puedes inspeccionarlo con la utilidad que publiqué aqui:

create object y Ocx | Gracias por la respuesta Antonio...
Si ya lo inspeccione con OleBrow...
SI, tenia un error de tipeo, ahora AboutBox, retorna el mismo error 1007, de error de argumento, a pesar que OleBrow dice :
STDCALL dispatch FUNX void AboutBox()
EL ocx fue creado en Chile, todos las variables estan en español.
Algun otro consejo..

create object y Ocx | Prueba a pasarle valores distintos a AboutBox() |
create object y Ocx | Probe con
AboutBox()
AboutBox("C")
AboutBox(1)
AboutBox(Chr(13))
AboutBox(Nil)
El mismo error... WinOle 1007 Argument Error:AboutBox
Y ni siquiera puedo obtener el codigo de estado del periferico que se encuentra en la variable ESTADO
Aqui el OCX [url:2g2srx0f]https://dl.dropboxusercontent.com/u/26565274/ocxsam350.ocx[/url:2g2srx0f]
El nombre del OCX es "OCXSAM350.Ocxsam350Ctrl.1"
En los Win64 se copia en Windows/Syswow64, y se registra son REGSVR32 OCXSAM32, en consola con derechos de administrador
Por si alguien puede a lo menos obtener el valor de las variables o ejecutar el AboutBox
Gracias de antemano

create object y Ocx | Adolfo,
A mi me aparece este error al intentar registrarlo:
[img:7cos5481]https://bitbucket.org/fivetech/screenshots/downloads/ocx_error.JPG[/img:7cos5481] |
create object y Ocx | Antonio...
La llamada al simbolo de sistema debe ser con derechos de administrador, es decir, ejecutar como administrador.
Si no sale ese error.
Probado en Win7 y win10, y lo registra sin problemas asi. |
create object y Ocx | adolfo, puede que si o puede que no, pero te puede ayudar:
una vez registré un ocx en syswow64, pero también tuve que hacerlo en el system32, así que copia y registra tu ocx en system32, fue la única forma para que funcionara un programa hecho en otro lenguaje.
saludos |
