hi,

i found a dll (http://www.zip-dll.de/download.htm) which may give my
application the possibility to extract zip files.

now i get this dll und use implib to create a lib file which i add to my
project. no i have this code:

extern "C" void __declspec(dllimport) IB_UnZipArchiveFile(const char*
szArchive);

void __fastcall TForm1::Button1Click(TObject *Sender)
{
String file = GetCurrentDir() + AnsiString("\\test.zip");
IB_UnZipArchiveFile(file.c_str());
}

when i compile, i get this error

[Linker Fehler] Unresolved external '_IB_UnZipArchiveFile' referenced from
C:\PROGRAMME\BORLAND\CBUILDER5\PROJECTS\ZIP\UNIT1.OBJ

what does this error mean. may the function works, when i load it dynamical
from the dll? how can i do this?

jens
