javascript - VBScript slow byte array copy -

-

i using following code read in binary file in vbscript , store in byte array access javascript , copy js array, sneaky way (the way!) i've found of reading binary data in js.

function readbinaryfile(filename)     dim instream,buff      set instream=createobject("adodb.stream")     instream.open     instream.type=1      instream.loadfromfile filename      buff=instream.read()     instream.close      dim bytearray()      dim     dim len     len = lenb(buff)      redim bytearray(len)      = 1 len         bytearray(i-1) = ascb(midb(buff, i, 1))     next      readbinaryfile=bytearray end function

it appears work expected, problem being seems extremely slow. example, reading in 300kb file can take on 2 minutes. expecting read files around 2meg.

could explain why such slow operation , if there's can speed up?

thanks.

the problem loop. try using disconnected recordset conversion:

function rsbinarytostring(xbinary)     'antonin foller, http://www.motobit.com     'rsbinarytostring converts binary data (vt_ui1 | vt_array or multibyte string)     'to string (bstr) using ado recordset      dim binary     'multibyte data must converted vt_ui1 | vt_array first.     if vartype(xbinary)=8 binary = multibytetobinary(xbinary) else binary = xbinary      dim rs, lbinary     const adlongvarchar = 201     set rs = createobject("adodb.recordset")     lbinary = lenb(binary)      if lbinary>0         rs.fields.append "mbinary", adlongvarchar, lbinary         rs.open         rs.addnew         rs("mbinary").appendchunk binary          rs.update         rsbinarytostring = rs("mbinary")     else           rsbinarytostring = ""     end if end function  function multibytetobinary(multibyte)     '© 2000 antonin foller, http://www.motobit.com     ' multibytetobinary converts multibyte string real binary data (vt_ui1 | vt_array)     ' using recordset     dim rs, lmultibyte, binary     const adlongvarbinary = 205     set rs = createobject("adodb.recordset")     lmultibyte = lenb(multibyte)     if lmultibyte>0         rs.fields.append "mbinary", adlongvarbinary, lmultibyte         rs.open         rs.addnew         rs("mbinary").appendchunk multibyte & chrb(0)         rs.update         binary = rs("mbinary").getchunk(lmultibyte)     end if     multibytetobinary = binary end function

in case have readbinaryfile return "ascii contents" of file , use instead of array: readbinaryfile = rsbinarytostring(buf)

cocoa - Nesting arrays into NSDictionary object (Objective-C) -

-
i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
