• .NET Development SqlDataSource/DataField Bug in 2.0 ?

  I've come across an odd situation. If someone has a table where a column name contains a space, and you generate a SqlDataSource on that column, some interesting things happen if you try to bind them. When I tried to bind, (in a GridView), the column name First Name via DataField="[First Name]", it gave a runtime error stating that [First Name] cannot be found in the sqlDataSource. Oddly enough, I took the brackets out and just sent i ...Show All

• SQL Server Management Studio and dbo requirements

  Why is it that Management studio continues to raise an error to a user that does not have db_owner permissions, but is a member of the db_ddladmin role. I have tried to remove the amount of people who have db_owner in my development environments and in place grant db_ddladmin and db_securityadmin.

• Visual C++ Which is faster?

  I am currently using vb.net and am wondering if c++ can produce faster programs. The majority of my programs are small with about 50 - 60 controls (including tabcontrols, labels, trackbars, comboboxes, a menustrip and a status strip.) The programs run pretty good as a BASIC program but can lag uneccesarily. i.e. when changing tabs, and both tags have nothing but labels and linklabels on them. It shouldn't lag there. If c++ can produce these p ...Show All
