COL_ProgressBar[3].MaxValue = 230

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

// Based on the maximum value defined for the Edit control,
// change the top value
IF EDT_Price.MaxValue < 1,000,000,000 THEN
EDT_Price.MaxValue = 2,000,000,000
