Emulating Datatypes that are alien to VFP

Emulating Datatypes that are alien to VFP

Emulating Datatypes that are alien to VFP

(OP)
Hello,

Does anybody know how to emulate the double datatype found in other languages such as Visual Basic or C, within Visual FoxPro?

I am trying to fire a method within an ActiveX control that requires parameters created as doubles to be passed.  

RE: Emulating Datatypes that are alien to VFP

Hi Benji,
AFAIK, the double data type, in VFP, is only applicable to fields in a table. So, short of any API calls, try creating a cursor with fields of data type double, populate the fields with the values, and then pass them to the control. Kinda clunky, but worth a shot.

Example:
CREATE CURSOR Buffer (Pad B(15))
REPLACE Pad WITH whatever
ActiveX.method(Pad)

Once again, theory & totally untested.

Along these lines SCATTER NAME OMyRec may work also.  So you'd have a reference to oMyRec.myDoubleTypeField

Thanks for your feedback, I already tried passing entries from a type double field, no luck I'm afraid.  Setting the parameters passed to 0.0 worked.  

i.e.
LOCAL lcDouble1, lcDouble2
lcDouble1 = 0.0
lcDouble2 = 0.0

THSIFORM.MyOCX.MethodRequiringDoubles(@lcDouble1, @lcDouble2)

I was originally passing as an array.
