BYTE Data Type

[tekytippy]

I use VFP 7 to access something called Sage Data Objects made by Sage the accounts company that links to their Line50 Software. It has a data type of BYTE which I cannot access, (I can write to but I cannot read from) each time I do I get an error:- Expression Could Not Be Evaluated.

Sage say they know this is because VFP does not support the BYTE data type.

How can I get round this?

You're right of course that VFP can't handle the square brackets in that way, but COM objects can.

Actually, VFP can handle square brackets that way:

xx=create('brackettest')
?xx.arrprop['one']
?xx.arrprop['two']
?xx.arrprop[1]

DEFINE CLASS BracketTest AS Session
  DIMENSION ArrProp[5]

  FUNCTION ArrProp_Access( nc_Idx )
    do case
      case vartype(nc_idx)='C'
        do case
          case nc_Idx='one'
            return 1
          case nc_Idx='two'
            return 2
          case nc_Idx='three'
            return 3
          case nc_Idx='four'
            return 4
          case nc_Idx='five'
            return 5
        endcase
      case vartype(nc_idx)='N'
        do case
          case nc_Idx=1
            return 'one'
          case nc_Idx=2
            return 'two'
          case nc_Idx=3
            return 'three'
          case nc_Idx=4
            return 'four'
          case nc_Idx=5
            return 'five'
        endcase
    endcase
  ENDFUNC
  FUNCTION ArrProp_Assign( nc_Idx )
    * Do something
  ENDFUNC
ENDDEFINE

( I tested, and this works in vfp6 sp5 )

Wgcs,

Actually, VFP can handle square brackets that way:

Good point. I hand't thought of using an Access method in that way.

Yes they were based on a VB Code example. I'll try your suggestions and let you know.

Thanks very much.

Your suggestion of

objHeaderData.type

Throws up an OLE error and won't work. I traid all sorts of combinations and they only work as per my original example.
