(Sorry for my poor english.)

I have to manipulate a DbMemo in a file and copy it in a Memo.

Table.FieldByName('Memo1').Value is a Variant.

How is it possible to copy it in a Memo?


Many different ways. Two easy ones:

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!
