<oReport>:SetWhileExpression(cExpression, [nSection]) logic
Arguments
| cExpression | The new while expression for the specified section. |
| nSection | Optional section number. The default is the first section after the optional title section. |
Description
To set an optional expression used to implement a print while condition. Records are included into a section until the while expression returns FALSE (or there is no more records to process). This must be a valid expression or an empty string ("") to clear the while condition.
If you use fields in the expression, it is necessary to call RpReport:Connect2Source() prior to setting the while expression..
Example
// Set the while expression in section 2
oReport:SetWhileExpression("MyTable.MyField > 1", 2)
