Emulating Datatypes that are alien to VFP

[Benji]

Hello,<br><br>Does anybody know how to emulate the double datatype found in other languages such as Visual Basic or C, within Visual FoxPro?<br><br>I am trying to fire a method within an ActiveX control that requires parameters created as doubles to be passed.&nbsp;&nbsp;

Hi Benji,<br>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.<br><br>Example:<br>CREATE CURSOR Buffer (Pad B(15))<br>REPLACE Pad WITH whatever<br>ActiveX.method(Pad)<br><br>Once again, theory & totally untested.<br><br>Jon

Along these lines SCATTER NAME OMyRec may work also.&nbsp;&nbsp;So you'd have a reference to oMyRec.myDoubleTypeField <p>John Durbin<br><a href=mailto: > </a><br><a href= > </a><br>ICQ VFP ActiveList #73897253

Thanks for your feedback, I already tried passing entries from a type double field, no luck I'm afraid.&nbsp;&nbsp;Setting the parameters passed to 0.0 worked.&nbsp;&nbsp;<br><br>i.e. <br>LOCAL lcDouble1, lcDouble2<br>lcDouble1 = 0.0<br>lcDouble2 = 0.0<br><br>THSIFORM.MyOCX.MethodRequiringDoubles(@lcDouble1, @lcDouble2)<br><br>I was originally passing as an array.&nbsp;&nbsp;<br>
