Generally, data type conversion between ActiveX (Visual Basic and VBScript) and Java™ methods occurs automatically, as described in ActiveX to EJB bridge, converting data types. However, the byte helper function and currency helper function are provided for cases where automatic conversion is not possible:
Private Function GetIntFromJavaByte(Byte jByte) as Integer GetIntFromJavaByte = (CInt(jByte) + 128) Mod 256 - 128 End Function
' Currency Helper Types Private Type MungeCurr Value As Currency End Type Private Type Munge2Long LoValue As Long HiValue As Long End Type ' Currency Helper Functions Private Function CurrToText(ByVal Value As Currency) As String Dim Temp As String, L As Long Temp = Format$(Value, "#.0000") L = Len(Temp) Temp = Left$(Temp, L - 5) & Right$(Temp, 4) Do While Len(Temp) > 1 And Left$(Temp, 1) = "0" Temp = Mid$(Temp, 2) Loop Do While Len(Temp) > 2 And Left$(Temp, 2) = "-0" Temp = "-" & Mid$(Temp, 3) Loop CurrToText = Temp End Function Private Function TextToCurr(ByVal Value As String) As Currency Dim L As Long, Negative As Boolean Value = Trim$(Value) If Left$(Value, 1) = "-" Then Negative = True Value = Mid$(Value, 2) End If L = Len(Value) If L < 4 Then TextToCurr = CCur(IIf(Negative, "-0.", "0.") & _ Right$("0000" & Value, 4)) Else TextToCurr = CCur(IIf(Negative, "-", "") & _ Left$(Value, L - 4) & "." & Right$(Value, 4)) End If End Function ' Java Long as Currency Usage Example Dim LC As MungeCurr Dim L2 As Munge2Long ' Assign a Currency Value (really a Java Long) ' to the MungeCurr type variable LC.Value = cyTestIn ' Coerce the value to the Munge2Long type variable LSet L2 = LC ' Perform some operation on the value, now that we ' have it available in two 32-bit chunks L2.LoValue = L2.LoValue + 1 ' Coerce the Munge value back into a currency value LSet LC = L2 cyTestIn = LC.Value
