BUG: API Fails Passing Very Small Double Datatypes to VFP

RESOLUTION

NOTE: The file referenced in this article as Project1.dll is for example purposes only. Project1.dll is theoretical API library not installed by any version of Microsoft Visual FoxPro.

As a workaround, call the function through the FoxTools library.

This workaround example is based on the "Steps To Reproduce Behavior" section of this article. The code in this example is case sensitive; therefore, it must be typed exactly as it appears below:

   SET LIBRARY TO SYS(2004)+"FOXTOOLS"
   hh=REGFN32("getVal","C","F","Project1.dll")
   x = "0.00000000000000000000000000000000085555"
   ?CALLFN(hh,x)
				

This returns the correct value.

   DECLARE DOUBLE getVal IN Project1.dll STRING
   x = "0.00000000000000000000000000000000085555"
   ? getVal(x)
