Visual C# Question re top level types
Am new to C# and have a question. My understanding is that top-level types (not nested in another type) must be public or internal, and can't be private. Why is this What if you have, say, a helper class that will only be used by other classes in the same namespace Why wouldn't you want it to be private If you need such a helper class in the root of a namespace and next to other public or helper classes, simply set the access modifier of the class to internal. Why would this be a problem Going over some MSDN documentation a bit though, the definition of private as listed as “Access is limited t ...Show All

One of the key fields can have a null value. Whet I fill the table, only those rows where all of the key fields have values are read, i.e. the rows where one of the key fields is null are NOT brought into the table.

Visual Basic Problem populating table with a SQL Cursor from VB GUI
Hi all I have a store proc that that does various bits of data manipulation, but the last part I have used a cursor to update 2 fields in a table. This sp is called by a VB front end and then the contents of the table in question displayed in a Crystal Report. The problem is, if I run the sp directly (within VB's Server Explorer) these 2 fields are always fully populated. If however I call the sp from within code in a GUI, after each call (which should fully populate the table based on certain criteria) the 2 fields become less populated. What I mean by this is on the 1st call the 2 fields are 100% populated, with each su ...Show All
