The MinValue property is used to:
  • get and set the bottom value of a report based on a data file. The bottom value is the minimum value allowed for the search key of the HFSQL data file the report is based on.
  • get the minimum value of the current filter (set by HFilter) on an HFSQL data file, view or query.
  • get the minimum value of a data series in a chart.
  • get and set the minimum value for some types of controls.
Example
Reports and Queries
// Print customers between "DUPONT" and "DURANT"
RPT_MyFileReport.MinValue = "DUPONT"
RPT_MyFileReport.MaxValue = "DURANT"

Remarks

Bounds for a report based on a data file

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

Limits for a report

The MinValue property can only be used on reports based on data files. When creating the report, you need to specify that the search is bounded by the minimum value.

Limitations
