Re: Null Values

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Am using SQL Server 2000. The tables use a default of 0 for the bit fields.
Have been using VB for years and never hit any serious data problems like
this.
Am trying to keep myself upto date and with my initial attempts at data with
VB.NET has resulted in disaster. In my ignorance have used the DataForm
Wizard and really screwed up the data because there was a Null value for a
checkbox.
This is a known bug but there are dozens of fixes published but, because am
new to VB.NET am not sure of the merit of each fix. Also getting the same
problem with a combo box.
Because am not familiar with the sequence the data events are fired, am not
sure where to place the fix code, or what data object to apply it to. Am
used to connections and recordsets but all these datasets and adapters are
very bewildering to a novice.

Thanks in advance for any help.
