I am trying to figure out where in VFP to put the code for the snippets found in this .spr file that would closely match an event or event(s) in VFP. It may be kind of hard to understand, but for all practical purposes it checks the user id, password and user count among other things.

I just want to know what in a VFP window (form) became or took the place of the Setup snippet, Proc snippet and that kind of stuff.

Sorry to be so blind.


Thanks Much!!!


Scott Rome was not built in a day. Be patient!

 

[danceman]

Setup snippet was replaced with a data environment for setting up the data. Or the Load event of the form.

the load event of the form happens after the data enviroment and before any forms objects become initilized.
after the objects are initilized then the forms init event happens.

other events you need to look at are:
unload
destroy
queryunload

you have lots more choices now. it is a matter to read up on each to find out which one should be used for what suits your needs. Attitude is Everything

 

[rgbean]

This maybe one of those times to take &quot;practical purposes&quot; description and simply create a new form - most of this code is unnesessary in VFP.

The easiest part of conversion is rewriting!
