Hi
I'm hoping somebody can help me with the following problem that has occurred
to me.
Suppose I have two tables in an SQL Server database. Let's call these tables
A and B. Assume that A has two fields: a primary key and another holding a
string. In table B there are three fields: a primary key, a foreign key
(which links to the primary key in A) and other field holding a string.

Situation:
I am writing a program that opens up a data file (file ext .dbf),
imports the information into a dataset. The program also, searches
through the dataset for key words ("company names") and then displays
all records with company names in a datagridview.
Once the information has been binded to the datagridview control, I
allow the user to select all records that are not companies, for
example, during the search the key word...

Hi There
I'm not sure what exactly is going wrong here. I'm writing an application that retreives a table from a database (tbl_internalfaults) and updates it. (Actually, just the status column will need updating with 'CLOSED' where necessary.)
I have been trying to use the OLEDB command builder to build the statement to update the database however it is returning an error whenever I try to do this.
I already have a dataset full of data, 1...

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:
