FPSpreadsheet: set a cell to #N/A

[upsidasi]

Hi,

What is the correct way to set a cell to #N/A in FPSpreadsheet?

I tried the following options:

• molWS.WriteNumber(ARow, ACol, Nan);  ==> doesn't work
• molWS.Writeform WriteCellValueAsString(ARow, ACol, '#N/A');  ==> doesn't work
• molWS.Writeform WriteText(ARow, ACol, '#N/A');  ==> doesn't work
• molWS.WriteFormula(ARow, ACol, '#N/A'); ==> it works, but is it the way to go?

Would it be different if I wanted to set a cell to #NUM! or #VALUE! ?
Thanks!

Code: Pascal  [Select][+][-]

1. type
2.   TsWorksheet = class(...)
3.     function WriteErrorValue(ARow, ACol: Cardinal; AValue: TsErrorValue): PCell; overload;
4.     procedure WriteErrorValue(ACell: PCell; AValue: TsErrorValue); overload;

where TsErrorValue is declared in unit fpsTypes

Code: Pascal  [Select][+][-]

1.   {@@ Error code values
2.     @value  errOK                  ok, no error
3.     @value  errEmptyIntersection   A space was used in formulas that reference multiple ranges; a comma separates range references (#NULL!)
4.     @value  errDivideByZero        Trying to divide by zero (#DIV/0!)
5.     @value  errWrongType           The wrong type of operand or function argument is used (#VALUE!)
6.     @value  errIllegalRef          A reference is invalid (#REF!)
7.     @value  errWrongName           Text in the formula is not recognized (#NAME?)
8.     @value  errOverflow            A formula has invalid numeric data for the type of operation (#NUM!)
9.     @value  errArgError            A formula or a function inside a formula cannot find the referenced data (#N/A)
10.     @value  errFormulaNotSupported This formula is not suppored by fpSpreadsheet (error code not used by Excel and Calc)   }
11.   TsErrorValue = (
12.     errOK,                 // no error
13.     errEmptyIntersection,  // #NULL!
14.     errDivideByZero,       // #DIV/0!
15.     errWrongType,          // #VALUE!
16.     errIllegalRef,         // #REF!
17.     errWrongName,          // #NAME?
18.     errOverflow,           // #NUM!
19.     errArgError,           // #N/A  ( = #NV in German )
20.     errFormulaNotSupported // No excel error
21.   );

Thank you wp!

I clearly need a new pair of glasses!
