>Howdy All,
>Does anyone know of a way to turn an array into a string quickly? I have to pass both arrays of bytes and binary strings to COM servers and clients. CreateBinary() is great at the conversion from string to array but I have been having to manually convert arrays to strings,(cData = cData + aData[x]...) MUCH slower, esp. with a 50k array. Thanks in advance.

Gary,
String concat. is painfully slow in Fox. I try to mimic C way (but not in memory) for such things. I cannot use memory as a stream but a file :
lcTempFile = "X"+sys(2015)+".tmp"
lnHandle = fcreate(lcTempFile)
lnElems = alen(myArray,1)
for ix = 1 to lnElems
   =fwrite(lnHandle,myArray[ix,1])
endfor
lnSize = fseek(lnHandle,0,2)
= fseek(lnHandle,0,0)
lcStr=fread(lnHandle,lnSize)
=fclose(lnHandle)
erase (lcTempFile)
