Hi,
Thank for your advise.
Some of my printer function is not working under ??
command even thought I though I think of using them.
For example
Actual command
Chr(27)+chr(83)+chr(1)
My code example under VFP list below is not working,
I won't know why. Any ideal ?
* sample NOT working using ??
* the chr(27) is taken out as
* font 'control' is acting on behalf of it
SET PRINTER FONT "Control",10
?? chr(83)+chr(1)
* sample working using ???
??? chr(27)+chr(83)+chr(1)
>THose guys work well - even with a GETPRINTER() dialog. I hope fox retains those features (as well as @SAY), because there are some things that [simply] cannot be done without lowlevel access to the pinter.
>
>??? is an inline method for sending control codes to the printer. It works with both set device to prin and set printer on.
>
>THe ?? feature only works with SET PRINTER ON.
