Need help with Delphi code

[sonya795]

Hello everyone,
I need some assistance in finding an error in my Delphi code. (I am new to the Delphi programming). I am using a Delphi application to build an excel spreadsheet.
When a part_number is entered for the first time(assuming it exists in db) application always runs , the second time the spreadsheet comesback with no data. Like my code is skipped ( while QRY.eof = False do -line is skipped). PLease help, below is my code.

Thank you in advance,

Try

while not (eof(QRY)) do

eof is a function rather than an atribute to the file.

Hope this helps,

Tom

Thank you Tom,
I changed the code to
while not QRY.eof do
The first record run fine and the second retuns nothing in the excel speadsheet.
Any other recommendations?

Thank you again,
Sonya

[espSquall]

I meant that the eof should look like this

eof(QRY)

If this comes up as an error try adding system to the uses,

I figured out what was wrong: applied RightTrim and LeftTrim functions to part number text field. For some unknown reason, a program was adding an extra space to each second part. Sonya
