Paco / Antonio;

He podido incorporar la función, pero no me hace nada. Tal vez no la uso de manera correcta. Abajo un ejemplo de la forma en que la estoy usando.

DEFINE SBUTTONBAR oBar OF oChildWnd SIZE 40, 40
Degrada( oBar:hDC, { 0, 0, oBar:nHeight, oBar:nWidth }, CLR_WHITE, nClr1, .t. )

El resultado es el mismo que sin el uso de la función Degrada.

Use Assim :
VTabDegrade(hWnd,hDc,nRgb(255,255,255),nRgb(000,000,128),0,1)
Inclua no seu lnk a lib :
\Bcc55\Lib\Psdk\msimg32.lib

No sé como usarla.

La compilo con BCC32?

La incluyo en uno de mis .prgs entre #pragma BEGINDUMP y #pragma ENDDUMP?

Intenté ambas y recibo muchos errores.

Mi intención es lograr hacer un "gradient" en dialogos y en buttonbar objects.

Gracias,

Reinaldo.

Olá,
Crie um .C dele.
Ex :
Reinaldo.C
Com o Borland, compile assim :

set bcdir=C:\Borland\BCC55
set fwhdir=C:\FwH

%bcdir%\bin\bcc32 -M -c -D__HARBOUR__ -I%fwhdir%\include;%hdir%\include Reinaldo.C

Irá criar o Reinaldo.Obj

No seu Lnk, inclua com os outros Obj, e inclua a Lib que eu disse :
\Borland\Bcc55\lib\psdk\msimg32.lib

Para executar, dentro do seu PRG, use assim :
Define Dialog oDlg ....

Activate Dialog oDlg On Paint VTabDegrade(oDlg:hWnd,oDlg:hDc,nRgb(255,255,255),nRgb(000,000,128),0,1)

Buena explicación.

Listo.

Cuando compilo con clipapi.h recibo varios errores como estos:

Sin clipapi.h recibo varios warnings pero no errores.
Pero ahora recibo estos errores cuando hago el Link con el gradient.obj y msimg32.lib:

Hello Vagner, Antonio

I got this warning below:

Warning W8057 VTDegrade.C 86: Parameter 'nMode' is never used in function VTDegrade

How to fix it?

Regards,

Richard

Richard,

You can safely ignore that warning.
