Slow Running Code

[Brent Boshart]

Any idea why this code takes over 6 minutes to run (Pentium II 233, 64mb ram)?

Rawdata is a fixed STRING of length 156960 bytes, mapdata() and t are of type LONG

FOR t=1 TO 26160
mapdata(1,t)=CVI(RawData,1+(t-1)*6)
mapdata(2,t)=CVI(RawData,3+(t-1)*6 )
mapdata(3,t)=CVI(RawData,5+(t-1)*6 )
NEXT t

Rawdata is read from a file. If I read it in 6 byte chunks and convert then it will run in 2 seconds. So I assume the problem is the huge string, but I would not expect 6 minutes!

Brent --
replace all to
ReDim mapdate(1 : 3, 1 : 26160) As Integer At VarPtr(RawData)

For dynamic strings use StrPtr instead of VarPtr
