Ingles:

Greetings to all, I hope you are well.

I apologize for the moletias. I would like if you can help with what I'm going to ask you now.

I have a DBF table that I filled with several records.

I use the dc_workarea2excel () instruction to export that table to excel. All perfect, the problem is that I have an alphanumeric field that contains characters that starts with 031, for example. When you export the table to excel in that column, you lose 0 and only put 31.

Could you give some help with this topic? Thanks in advance.

Español:

Saludos a todos, espero que estén bien.

Pido disculpas por las moletias. Me gustaría preguntarte ahora.

Tengo una tabla DBF que llené con varios registros.

Uso la declaración dc_workarea2excel () para exportar esa tabla a Excel. Todo perfecto, el problema es que tengo un campo alfanumérico que contiene caracteres que comienzan con 031, por ejemplo. Cuando exporta la tabla para sobresalir en esa columna, pierde 0 y solo pone 31.

¿Podrías dar alguna ayuda con este tema? Gracias por adelantado.

Una manera rápida , es renombrar el archivo .dbf a .xls

y otra alternativa es usar esta librería

HBLibXL.PRG - Klassendefinitionen für Xbase++ und LibXL.DLL
* HBLibXL.PRG - CLASS CODE for Xbase++ und LibXL.DLL
** My Homepage: http://www.familie-brandel.de (german
* http://www.familie-brandel.de/index_e.html (english)

A quick way is to rename the .dbf file to .xls.
and another alternative is to use this library LibXL.DLL

Mr. thank you very much for your attention.

I can complete the idea of what I want to do.

That table that filled with several dbf
of invoices, returns, credit notes, etc. I need it to arrive organized to excel by a column specified in this case by the column IDCLIE as you will see it in the table that you send as an example.

Thank you

Epañol:

Sr. muchas gracias por su atencion.

Le puedo completar la idea de lo que quiero hacer.

Esa tabla que lleno de varios dbf
de facturas, devoluciones, notas de creditos, etc. la necesito que llegue organizada a excel por una columna especifica en este caso por la columna IDCLIE como usted lo vera en la tabla que le envie de ejemplo.

Gracias

I am guessing that you have an older version of eXpress++.

This problem was resolved several years ago in eXpress++ code.
Attached is Worksheet.xls created from the most current version.

You need to modify your DC_WorkArea2Excel() function in _DCFUNCT.PRG.

Then you need to rebuild your DCLIPX.DLL by running BUILD19_SL1.BAT or BUILD20.BAT

Here is the source code for the most current version of DC_WorkArea2Excel().

Code: Select all

FUNCTION DC_WorkArea2Excel( cExcelFile, nOrientation, lDisplayAlerts, ;
                            lVisible, aFields, lAutoFit, cDateFormat, aFieldEvals, ;

      cDbfName, nKeyCount, oProgress, lStatus := .t., aData, ;
      cRow, cColumns, cRange, aRow, bError, aStru2, nFound, ;

that is a Constant of Excel COM.

you can get these COM Constant using Tlb2Ch.exe and CLSID or ProgID

open a CMD Box and copy/ paste this

Code: Select all

Tlb2Ch.exe "Excel.Application" >> EXCEL.CH

you will get EXCEL.CH with all Constant of Excel COM

p.s. Tlb2Ch.exe is found in same Directory like XPP.EXE

Eugene Lutsenko · #10 Post by **Eugene Lutsenko** » Wed Apr 24, 2019 9:58 pm

The reason for the described problem is that the number with leading zero is perceived as a number, not as a text. There are several very simple ways to fix this.
1. Make a fictitious string in the database with text values in the fields. Then the entire field will be treated as a text type field.
2. Instead of the number 0 to write the letter O.
3. Before numbers with leading zeros to put some character, can be not displayed.
