MaxValue (Property)

In french: BorneMax

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

// Print the customers found between "DUPONT" and "DURANT"
RPT_MyFileReport.MinValue = "DUPONT"
RPT_MyFileReport.MaxValue = "DURANT"

// According to the upper bound defined for the edit control,
// change this upper bound
IF EDT_Price.MaxValue < 1,000,000,000 THEN
EDT_Price.MaxValue = 2,000,000,000
END

<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.

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.

<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.

Limit for a window control

The value defined for the upper bound cannot be less than the value defined for the lower bound. The minimum value is returned by the MinValue property.

Limitations

This property can be used on the following types of controls:

Calendar controls.
numeric edit controls (no number greater than this value can be entered).
Duration edit control (no duration greater than this value can be entered),
Chart controls.
Numeric table columns.

The default value for the upper bound is defined in the window editor when describing the control ("Details" tab).

This property can be used on the following types of controls:

numeric edit controls (no number greater than this value can be entered).
