Variant will store all the different possible VB
data received at one place 7. Why is it not good to use a variant data type? Using variant rather than a specific data type is slower because of conversions needed and takes up more memory because additional over head 8. What is the difference between a Dynaset and Snapshot and how would you create one? (we dont use snapshot in VB5+) A dynaset-type Recordset object is a dynamic set of records that can contain fields from one or more tables or queries in a database and may be updatable. In an ODBCDirect database, a dynaset-type Recordset object corresponds to an ODBC keyset cursor. Remarks A dynaset-type Recordset object is a type of Recordset object you can use to manipulate data in an underlying database table or tables. It differs from a snapshot-type Recordset object because the dynaset stores only the primary key for each record, instead of actual data. As a result, a dynaset is updated with changes made to the source data, while the snapshot is not. Like the table-type Recordset object, a dynaset retrieves the full record only when it's needed for editing or display purposes. A snapshot-type Recordset object is a static set of records that you can use to examine data in an underlying table or tables. In an ODBCDirect database, a snapshot-type Recordset object corresponds to a static cursor. Remarks To create a snapshot-type Recordset object, use the OpenRecordset method on an open database, on another dynaset- or snapshot-type Recordset object, or on a QueryDef object. 10.How would you define and use a Boolean in VB? (Integer in VB3 Boolean in VB6+)
Dim [Private][Public] x as Boolean
Default is false
11. What is the difference between Dim nCount as Integer vs Dim nCount% and when would you use each?
No difference
12.What is the difference between <F8> and <Shift-F8> when debugging?
F8- will take u through all the executable
statements
<SHIFT> f8 will skip the calls to subroutines
13.What is the statement to extract 4 characters from the middle of a string? Mid(string, start [, length] ) 14. What is the error message that you would get if you try to assign "Null" to an integer variable?
