Hello,

I have a defined a class using the following code in myprg.prg and then build a DLL file (mydll.dll).
*---------------------------------------------*
DEFINE CLASS testclass as CUSTOM olepublic
PROCEDURE FormatPrice
PARAMETERS MyPrice AS String
WAIT WIND MyPrice
RETURN MyPrice
ENDPROC
ENDDEFINE
*---------------------------------------------*
**Created an object
xobj = CREATEOBJECT("mydll.testclass")

xobj.Formatprice

While using the function, it is giving an error like :-

OLE IDISPATCH EXCEPTION CODE 2031 FROM MYDLL.TESTCLASS
MYDLL.TESTCLASS: .FORMATPRICE MYPRG.PRG ERROR IN LINE
4 USER INTERFACE OPERATION NOT ALLOWED AT THIS TIME.
2031...

Can someone advice me how to RESOLVE the problem.
