Stored procedures
The MaxValue property is used to:
  • find out and modify the upper bound for a report based on a data file. The upper bound is the maximum value allowed for the search key of the HFSQL data file used as report source
  • find out the upper bound of the current filter (defined by HFilter) on an HFSQL data file, view or query.
  • find out the maximum value of a chart series.
  • find out and modify the maximum value for some types of controls.
Example
Reports and Queries
// Print the customers found between "DUPONT" and "DURANT"
RPT_MyFileReport.MinValue = "DUPONT"
RPT_MyFileReport.MaxValue = "DURANT"
Syntax

Finding out the upper bound defined for a control or report Hide the details

<Current value> = <Element used>.MaxValue
<Current value>: Character string
Current value of upper bound:
  • for the report based on a data file.
  • for a control found in a window or page.
<Element used>: Control or report name
This parameter corresponds to:
  • the name of the report used (report based on a data file).
  • the name of the control with the upper bound value (control in a window or page). The list of controls concerned is located in the "Limitations" paragraph.

Modifying the upper bound of a control or report Hide the details

<Element used>.MaxValue = <New value>
<Element used>: Control or report name
This parameter corresponds to:
  • the name of the report used (report based on a data file).
  • the name of control whose upper bound must be modified (control in a window or in a page).
<New value>: Integer
New value of the upper bound:
  • for the report based on a data file.
  • for a window control. The list of controls concerned is located in the "Limitations" paragraph.
Reports and Queries

Finding out the upper bound defined for the current filter Hide the details

<Current value> = <Element used>.MaxValue
<Current value>: : Type corresponding to the filter used
  • Current value of upper bound for the filter currently used on the specified element. This filter was defined by HFilter.
  • Empty string ("") in the following cases:
    • no filter was defined for the specified element.
    • the filter is disabled.
    • no bound was specified for the filter.
<Element used>: Character string
Name of data file, query or view used.
Reports and Queries

Finding out the maximum value of a chart series Hide the details

<Maximum value> = <Series>.MaxValue
<Maximum value>: Integer
Maximum value of the series. This value exists only if it was calculated (if the series was drawn for example).
<Series>: Character string
Series to use. Use the following notation: <Chart name>[<Series number>].
Remarks

Bounds for a report based on a data file

Bounds select only those records whose search key is between the lower bound value (returned by the MinValue property) and the upper bound value (returned by the MaxValue property).

Limit for a report

The MaxValue property can only be used on reports based on HFSQL data files. When creating the report, you must specify that the browse is bounded by the maximum value.

Limitations
