CHAR to WCHAR ??

Sounds like you need to link to the LiteZip library. I've never used it but there should be either an import library if it's implemented as a DLL or else a static library. LiteZip.lib? Mark
Yea, there is both. The LiteZip.dll I placed in the windows\system32 folder while the LIB file I placed in the LIB folder under VC8. Obviously there more I need to do. So I need to write the code in to tell that the DLL is there and where it is ? Pete

Generally you want to keep 3rd-party dlls in the same folder as your app unless the vendor explicitly states to move it to a system folder. This helps prevent versioning clashes with other applications. The lib file can stay where it was (for the same reason I suppose). This is from VS 2003 so may be a bit different on 2005... In solution explorer - right click your project and select Properties. Go to the Linker/Input section and add the libfile pathname to the Additional Dependencies line. For example "C:\LiteZip\Lib\LiteZip.lib". Substitute the actual path and file name as usual. If there's multiple lib files on the line then separate them with a space. Should link! :) Mark

Any reason you did not suggest using a #pragma?
#pragma comment(lib, "LiteZip")
It's a lot easier, and if the #pragma line is placed in the LiteZip.h header file it is something that one never has to remember to do when using the library.
You may be right
I may be crazy

That's it Mark, Now it compiles and end up with an EXE. Where did you learn all this ?? Just reading out of books or have ya done some courses ? Pete :-D

Lots of books (measured in pounds/Kgs I guess) and I started PC programming before there was Windows :) Man, I'm old. I don't miss command-line compiling/linking/building one bit! I'm still always learning though - that's why it's handy hanging out here. Cheers! Mark

I left that for you to suggest! I suggest you suggest it to the OP :laugh: Thanks for the tip! Mark

you can add libaray file just like adding c++ file~!

I am trying to write a simple application that is capable of zipping files. To do this I am using ‘LiteZip’. I am writing with Visual C++ 2005. The code which generates the error is: #include "litezip.h" HZIP hz; ZipCreateFile(&hz,"FileName.zip",0); The error message is: error C2664: 'ZipCreateFileW' : cannot convert parameter 2 from 'const char [9]' to 'const WCHAR *' Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast From what I understand, I need to convert a CHAR to WCHAR. This is done by…. ?? Regards Pete :doh:

Thanks Dave, I have come across from using Borland's Delphi, so it's difficult coming to terms with some of the coding. Fritzables.
