datareaders initialization

[janilane]

hi, can anybody tell me how to initialize datareaders so i can avoid warnings such as "Variable 'mydatareader' is used before it has been assigned a value. A null reference exception could result at runtime."

thanks

you can assign it a nothingness, just to be explicit with the compiler:

dim mydatareader as sqldatareader = nothing

In most cases you would assign it directly:

dim mydatareader as sqldatareader = somesqlcommand.executereader
