Hi,
There is FindByColName() function which is used to find a row in a table based on the column value.
for eg.
dsEmployees.tblEmployees.FindByFirstName("Kiran")
Now my typed dataset dsEmployees doesn't contain tblEmployees anymore, It contains a View in it(VewEmployees) and no primary key also.

This is a question that someone familiar with ASP.NET and ADO.NET DataSets
and DataTables should be able to answer fairly easily. The basic question is

dataset, using a common key. I will first describe the problem in words and
then I will show my code, which has most of the solution done already.
I have built an ASP.NET that queries an Index Server and returns a...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
