Well, as I understand funtion DoubleToNum it converts data to valid double one before calling DLL. The following is the code I use:

set proce to clsheap addi && Ed clsheap class

ascmx = replicate(chr(0),8*10)
xdata =DoubleToNum(ascmx) && Is this OK ?

retval=MyDll(,,@xdata)

The C0000005 error appear after that.

Must I convert LONG data type too?


Thanks.
