Antonio,

He añadido al fuente de arriba este código:
Code: Select all  Expand view
extern "C"
{
    LPWSTR AnsiToWide( LPSTR );
}

HB_FUNC( CONNECTDB )
{
  LPWSTR pW = AnsiToWide( hb_parc( 1 ) ) ;

  hb_retnl(ConnectDB( TEXT( "\\My Documents\\test.sdf" ) ) ) ; // asi devuelve S_OK
  //hb_retnl( ConnectDB( (LPTSTR) hb_parc(1) ) );
  //hb_retnl( ConnectDB( pW ) );
  //hb_xfree( pW );
}   

HB_FUNC( COINITIALIZEEX )
{   
    hb_retnl( CoInitializeEx( NULL, COINIT_MULTITHREADED ) );
}   

HB_FUNC( COUNINITIALIZE )
{
    CoUninitialize();
    hb_ret();
}   


Programa de test:
Code: Select all  Expand view
Function Main()
LOCAL cDatabase :="\\My Documents\\test.sdf"
  Msginfo( COINITIALIZEEX() )
  Msginfo( CONNECTDB( cDatabase ) ) // como parametro devuelve -2147467262 
Return nil


Las valores devueltos son S_OK, parece funcionar.
Pero no consigo pasar como LPTSTR la cadena con con el nombre de la base de datos.
Como puedo hacerlo.

Gracias.
Saludos

Salvador,

Desde PRG decláralo asi:

LOCAL cDatabase :="\My Documents\test.sdf"

y en C, lo tienes bien:
Code: Select all  Expand view

HB_FUNC( CONNECTDB )
{
  LPWSTR pW = AnsiToWide( hb_parc( 1 ) ) ;

  hb_retnl( ConnectDB( pW ) );
  hb_xfree( pW );
}  
 
regards, saludos

Hola buenas,

Quiero hacer pruebas acceciendo a SQLSRV, con fwppc 2007 y windows CE 6.0. No consigo compilar el .c con el .h. He añadido los dos trozos de c a un solo fichero SQLSVRCE.c y lo que puesto para compilar en el bat así:

%vcdir%\bin\clarm -W3 -c /DARM /DUNICODE /I%hdir%\include /I..\include SQLSVRCE.c

Está claro que lo estoy haciendo mal.¿Cómo podría hacerlo?

Gracias de antemano

Antonio,

Lo que hice fue coger el código de Salvador, uní los dos fragmentos de código en un fichero .c llamado sqlsrvce.c, cree su .h el cuál lo he situado donde tengo los prg y esta es la lista de errores que me da.

Me da error en vce\include\SSCEOLEDB.h que no he modificado, su fecha es de 04/2003. A lo mejor no tengo el fichero adecuado.

Gracias de Antemano

Roberto,

Parece que ISSCECompact está definido en sqlce_oledb.h

Estas incluyendo ese fichero en tu fichero en C ?
#include <sqlce_oledb.h>
regards, saludos
