Grabbing a graphic from a returned web string

[Ken Elvehjem]

Hi,

At one time, I needed to be able to submit a URL to a webserver via TCPOPEN etc. for a graphic image (jpeg) and save it as a file when it came back.

Someone on the list (Lance, maybe) showed me to use the following format

Entire_Page = RIGHT$(Entire_Page, LEN(Entire_Page) - INSTR(Entire_Page, "JPEG") - 7)

Where "Entire_Page" is the whole string returned by the server.

Now I'm trying to do the same with PNG files, but it is not working out so good -- they seem always to be invalid files.

Any thoughts?

Found a solution

Found it...

Did a little more digging and learned that if I search for this string, which is the PNG header, and save everything after it, I get a PNG file: hexadecimal byte values are 89 50 4E 47 0D 0A 1A 0A

Found this in the WikiPedia.

So, we can shut this thread down.
