Hi,

Displaying data from the DataReader. Log on to http://www/vkinfotek.com for more articles on DataReader.

Basically what it is doing is looping thru a DataReader, while it has rows to loop thru. In each iteration of the loop, it is assigning values to the text properties of the 4 text boxes. Once that has comepleted, it closes the DataReader and the Connection, then enables a button.

IMHO, the code is flawed in the fact that it is using a while loop when it expects one row only. I believe it might be better to use the "if" statement to check to see if it has rows to read.

Hope this helps
Alec
