.net - Update Statement Updates 0 Rows Via The C# Winform Application?

I'm trying to update a row via c# winform application. The update query generated from the application is formatted correctly. I tested it in the sql server environment, it worked well. When i run it from the application i get 0 rows updated.Here is the snippet that generates the update statement using reflection - don't try to figure it out. Carry on reading after the code portion:

public void Update(int cusID)
{
SqlCommand objSqlCommand = new SqlCommand();
Customer cust = new Customer();

[code]....

The above final update statement works on the sql environment, but when running via the application, the execute non query runs ok and gets 0 rows updated!
