Hi, I need to know how can I unzip a file located in C:\Program files\ to this same directory, but I can't have any dialogs being shown during the process.

Cheers

you need to get zlib or zziplib. zlib is the full thing whereas zziplib is a thirdparty lightweight alternative

http://www.gzip.org/zlib/
http://zziplib.sourceforge.net/

you should find examples on how to use them on their sites

gzip and zip are diffrent things. And now zip have there version 9 which is not compatable with the old versions. I don't think info-zip supports zip version 9.

I didn't get how to use these libraries.

Can anyone give me the code to extract a zip file into a specified directory? That's all I need.

Is it realy code you need or how you use them in your enviroment?? What enviroment are you using. Windows, Unix? GCC, VC++, VC .NET, BCB or any other?

Look at this link for some code. Don't know if that helps you.
