Look at _WinAPI_ReadFile(). Edited August 16, 2009 by Yashied

Look at _WinAPI_ReadFile().

Thank you very much

I am very sorry

I did not understand the example in help book

Can you write a simple example of reading.

Thank you Very Much ..

I Like It,

It's very professional.

By the way, if you need information on the ZIP archive only, it is not necessary to read the whole file. Just read the first 30 bytes of this file.

Local file header signature (4 bytes) - 0x504B0304

Version needed to extract (2 bytes)

General purpose bit flag (2 bytes)

Compression method (2 bytes)

Last mod file time (2 bytes)

Last mod file date (2 bytes)

CRC-32 (4 bytes)

Compressed size (4 bytes)

Uncompressed size (4 bytes)

File name length (2 bytes)

Extra field length (2 bytes)

No Yashied, you are wrong about ZIP.

There is no central header inside ZIP file. Thing is more complex there.

This was discussed before on General help forum. The result was weaponx's script to read zip file (headers).

Though I would prefer DllStruct() solution his script is great for the job.

Search for it, you will see what I mean.
