1.怎么在單元之間轉換單元的坐標？

使用StiUnit類的ConvertFromHInches和ConvertToHInches方法可實現坐標轉換。
示例：

C#

//Converts a value from centimeters to inches
StiUnit unitFrom = new StiCentimetersUnit();
StiUnit unitTo = new StiInchesUnit();
double value = 2.54;
value = unitFrom.ConvertToHInches(value);
value = unitFrom.ConvertFromHInches(value);

VB

'Converts a value from centimeters to inches
Dim UnitFrom As StiUnit = New StiCentimetersUnit()
Dim UnitTo As StiUnit = New StiInchesUnit()
Dim Value As Double = 2.54
Value = UnitFrom.ConvertToHInches(value)
Value = UnitFrom.ConvertFromHInches(value)

2.怎么在報表中轉換坐標和尺寸？

所有可以實現IStiUnitConvert接口的類都可以通過使用Convert方法將一個單元中的報表的坐標和尺寸可以轉換到另一個單元。 例如：

C#

//Converts coordinates and sizes of a report from the current unit into inches
StiReport report = new StiReport();
StiUnit unitTo = new StiInchesUnit();
report.Convert(report.Unit, unitTo);

VB

'Converts coordinates and sizes of a report from the current unit into inches
Dim Report As StiReport = New StiReport()
Dim UnitTo As StiUnit = New StiInchesUnit()
Report.Convert(Report.Unit, UnitTo)

3.怎么輸出一個值來替代DBNull和空值？

You should use text formatting via the TextFormat property. Also you may disable forced conversion of null values using the report ConvertNulls property.
可以通過TextFormat屬性使用文本格式化。你也可以使用報表的ConvertNulls屬性來禁用強制空值轉換。
