if Not VarIsNull (aTable ['Memo1']) // it will be Null if it's blank or empty, i.e. ''
then aMemo.Lines.Text := aTable ['Memo1']
else aMemo.Clear;
or
aMemo.Lines.Text := aTable.FieldByName ('Mem1').AsString;
Thanx a lot!
I tried your way, but i have an error : Access violation at adress ...... .....
Do you have another suggestion of amelioration?
I gave you two methods, which caused and access violation? If it was both, then I would suspect your code. I did test the methods before posting them.
Sorry! i use your first method ... but it was with table using the component Tdbf (from sourceforge).
I'll try with a component Ttable BDE during the week-end!
Both methods should work with any tDataSet descendant. An alternate might be something like
aMemo.Lines.Text := VarToStr (aTable.FieldByName ('Memo1').Value)
I can't recall how VarToStr reacts to a Null variant, it should return ''. If it raises an Invalid Variant Conversion exception then one would have to test for Null before the line above.
