Seeing the code where the problem happens would help.


The Crazy One

<div>
PickZoneDM.PickZoneQry.Fie<wbr />ldByName('<wbr />WWS_MAXLDV<wbr />OL').AsFlo<wbr />at := null; &nbsp;<br />
<br />
Is there a problem with the conversion?<br />
Should it be: AsFloat := 0;
</div>


PickZoneDM.PickZoneQry.FieldByName('WWS_MAXLDVOL').AsFloat := null;  

Is there a problem with the conversion?
Should it be: AsFloat := 0;

<div>
Try this<br />
<br />
PickZoneDM.PickZoneQry.Fie<wbr />ldByName('<wbr />WWS_MAXLDV<wbr />OL').AsVar<wbr />iant:= null; &nbsp;<br />
<br />
or<br />
<br />
PickZoneDM.PickZoneQry.Fie<wbr />ldByName('<wbr />WWS_MAXLDV<wbr />OL').Clear<wbr />; &nbsp;<br />
<br />

</div>


Try this

PickZoneDM.PickZoneQry.FieldByName('WWS_MAXLDVOL').AsVariant:= null;  

or

PickZoneDM.PickZoneQry.FieldByName('WWS_MAXLDVOL').Clear;

Hi, <br />
This is probably a really basic question, but I am new to delphi and can't figure out the cause of the following error message: Invalid Variant Type Conversion.<br />
<br />
Any explanations would be appreciated?? <br />
<br />
Cheers
