checkbox oracle char type

[mrstrong]

Gday,

I have a checkbox on my windows forms that I need to set based on a
value in a dataset which is populated by an odp data adapter via a web
service.
The value in the oracle database is of type char(1) with possible values 'Y'
or 'N' (there are no boolean values in oracle).

The code (c#) that I currently have that is being called from the form's
load procedure to set the checkbox is as follows:

if (dsMyDataSet.Tables[<table>].Rows[0][<field>]== 'Y')

chkBox.Checked = true;

else

chkBox.Checked = false;

However there are two issues that I hope you might be able to point me
in the right direction with:

1. How do you do comparisons for type char? (I get this message:
Operator
'==' cannot be applied to operands of type 'object' and 'char')

2. I am not sure how to reference the current row in the dataset

If this is not the right forum please point me in the right direction.

Regards,

Peter

Hi,
You can use the ToString() functaion like this:
dsMyDataSet.Tables[<table>].Rows[0][<field>]== "Y"
Note:
It's "Y" not 'y'.
I hope that help you.

Sorry,last relpy have a mistake ,
you should add ToString() after that DataRow
like :
dsMyDataSet.Tables[<table>].Rows[0][<field>].ToString()== 'Y'
Sorry for that Mistake!
