checking binary data

[nabeels786]

im reading in binary data from the Inet control for movies.

sometimes it 404s however, and when i open the file in wordpad, the html 404 page is there. how do i check whether it 404d?

vtData = Inet1.GetChunk(256, 1)
tmplen = UBound(vtData)
length = length + tmplen 'get the total size
                        
 if instr(1,vtData,"404") then 
    ....

i tried that, doesnt work, when i debug.print it, its full of ? marks.

any ideas? i think its a conversion from binary to ascii, which i dont know how to do..

thanks

I think you have a byte array, not a string...

z = ubound(vtdata)
limit - z -2
For i = 1 to limit ' we won't worry about a character 4 too near the end
    if vtdata(i)=52 then ' a four
        if vdata(i+1) = 48 and vtdata(i+2)= 48 then
                      msgbox "404 found"
                      exit for
    end if
next

ah okidoke, thanks.

but there isnt a faster way? like checking the first x number of bytes, instead of checking every 255 that comes in?

actually, ill work on it. thanks
