Hi again my friends!

Only a doubt... How I can define a help for a get for exhibition when the user press the F1 key?

It's possible?

1.- SetHelpFile( "YourHelpFile.hlp" )
2.- When defining the Get control you should use the clause: HELPID YourHelpTopic

Then, when user presses th F1 key, program will show the defined topic.

Notice: YourHelpTopic can be a numeric or alphameric expression according to your help file's topic definition.

Regards.
