Replace string function

Sample : f_replace(powerbuilder,r,s) will return powesbuildes


f_replace(string as_text,string as_before,string as_after)  returns string

integer li_Posisi
string ls_return

li_Posisi = pos(as_text,as_before)
do while li_Posisi > 0
    ls_return += mid(as_text,1,li_Posisi - 1) + as_after
    as_text = mid(as_text, li_Posisi + Len(as_before))
    li_Posisi = pos(as_text,as_before)
loop
ls_return += as_text

return ls_text

cheers..

Keycode to string

With most objects, you can trap the key strokes using user events.
For example, on a datawindow object,
you can create a user event using Event Id = pbm_dwnkey.
In this event, you'll find a parameter of type keycode.
This is a predefined enumerated data type with values such as KeyA!, KeyB!, etc.
But if you want to convert this value to a string,
you'll find your choices are limited.
It looks something like this :

choose case a_key
       case keyA!
            ls_string = "A"
       case keyB!
            ls_string = "B"
       case keyC!
           ls_string = "C"
...
end choose




As simple as that!
Cheers..
