resolving a variable which contains a fieldname

[bdenson]

I have a program which populates a list with the names of the fields in the selected table.

Once the user selects a field, I now know which field he wants to work on, but how can I interrogate the contents of that field.

For example. user selects GENDER field.

THISFORM.mylist.value = "GENDER"

How can I count the number of empty GENDER fields, when all I have is THISFORM.mylist.value?

BTW I am an experienced programmer, but new to Visual FoxPro (V6). I.E. I will understand programming concepts, but don't assume I automatically know some foxpro quirks!

Thanks

Hi Barry,

Try something like:

fieldname = THISFORM.mylist.value
COUNT FOR EMPTY(&fieldname)

Hi,
& is a macro code i VFP.

If Temp = "Test"
a="temp"
Then...
? &a ......... will diplay "TEST"
? EVAL(a) .... will display "TEST"
? (a)......... will display "temp"

So dpending on situation, you can use & or EVAL

I am providing lttle more explanation to what Jim wrote. I agree with the code Jim provided....
fieldname = THISFORM.mylist.value
COUNT FOR EMPTY(&fieldname)
