Barra de progresso sem fim.

[Anderson.OL]

Olá a todos...

Bem, direto ao assunto.

Eu gostaria de fazer uma barra de progresso mas não tenho a informação de qdo a tarefa executada vai encerrar, sendo assim, quero uma barra de progresso somente para exibir que o programa está em execução, como no exemplo abaixo:

[jefe]

poco te puedo ayudar ya que acabo de empezar con esto y no se nada, pero para lo que tu necesitas se hace con METER

eso si, no te puedo explicar como funciona, porque todabia estoy intentando comprender como funciona esto.

un saludo

Anderson,

yo lo uso de la siguiente forma :

funcion genera_indices

MsgMeter( { | oMeter, oText, oDlg, lEnd | ;
CreaIndex( oMeter, oText, oDlg, @lEnd,mfil_ntx ) },;
"Tabla : " + ffil_dbf+" Tag : "+mfil_ntx,"Generando Indices")

return

//=================================================
FUNCTION CREAINDEX( oMeter, oText, oDlg, lEnd,mfil_ntx )
//==================================================

oMeter:nTotal = RECCOUNT()

INDEX ON &MCAMPO TAG (mFil_Ntx) TO (mfil_cdx) ;
EVAL ( oMeter:Set( RecNo() ), SysRefresh(), ! lEnd )

RETURN NIL

ojala te sirva

saludes desde Managua ,Nicaragua

Marquee Style

By creating the progress bar control with the PBS_MARQUEE style, you can animate it in a way that shows activity but does not indicate what proportion of the task is complete. The highlighted part of the progress bar moves repeatedly along the length of the bar. You can start and stop the animation, and control its speed, by sending the PBM_SETMARQUEE message. Marquee progress bars do not have a range or position.

#define PBS_MARQUEE 0x08
#define PBM_SETMARQUEE (WM_USER+10)

Utiliza el Estilo PBS_MARQUEE al crear el control .. modifica la clase ... eso no necesita explicación ...

y un ::SendMsg( PBM_SETMARQUE, nOn, nMilisegundos )

nOn = 1 o 0 , empezar a detener animacion

nMilisegundos = Numero de segundos de refresco de la animacion.

esto te debera de funcionar

Tambien puedes utilizar:

MsgRun("Aguarde por favor...",,{|| MiFuncion() } )
