This directory contains Visual C Sharp (C#) sample project for
|
||
|
|
using the unzip32.dll library. This project was generously donated
|
||
|
|
by Adrian Maull. The Zip source archive contains a corresponding
|
||
|
|
project for using the zip32.dll library.
|
||
|
|
|
||
|
|
These sample projects are distributed as part of the Info-ZIP distribution
|
||
|
|
under the Info-ZIP license.
|
||
|
|
|
||
|
|
Note that the files may be saved in "UNIX LF" format with carriage returns
|
||
|
|
stripped. These may need to be restored before the project can be successfully
|
||
|
|
used.
|
||
|
|
|
||
|
|
The project is based on .NET Framework 1.1. It was contributed
|
||
|
|
to the Info-Zip project April 2005. If you have questions or comments,
|
||
|
|
contact us at www.Info-ZIP.org or for specific questions about these
|
||
|
|
projects contact Adrian Maull directly at adrian.maull@sprintpcs.com.
|
||

|
See UnZip.cs for more detailed information about the project. Currently
|
||
|
|
the sample project has some bugs as noted in the above file.
|
||
|
|
|
||
|
|
The original code has been adapted to the modified WinDLL interface of
|
||
|
|
UnZip 6, using Visual C# 2005 (.Net Framework 2.0) and a unzip32.dll compiled
|
||
|
|
by Visual C++ 6.0. The provided project file is still in the format for
|
||
|
|
Visual Studio 7.1 (VS .Net 2003, .Net 1.1). But the code of the project
|
||
|
|
can be used with newer Visual Studio versions (2005 = 8.0 or 2008 = 9.0);
|
||
|
|
only the project file gets (irreversibly) converted to the newer Visual
|
||
|
|
Studio format when first opened.
|
||
|
|
|
||
|
|
However, this project is not tested throughoutly by us at this time.
|
||
|
|
|
||
|
|
Note on using Visual Studio C# 2005, 2008 (or newer?):
|
||
|
|
The UnZip maintainer was unsuccessful to run the C# sample code using
|
||
|
|
Visual Studio 2005 or 2008 together with an unzip32.dll compiled with
|
||
|
|
the same Visual Studio version in default configuration (unzip32.dll linked
|
||
|
|
against the DLL version of the C runtime library). The C# program failed
|
||
|
|
to load the unzip32.dll because of an "OS loader lock" conflict. This conflict
|
||
|
|
should only show up when loading "mixed mode" dll that contain both managed
|
||
|
|
and unmanaged code. So, it cannot be caused by the "pure native code"
|
||
|
|
unzip32.dll directly, which contains nothing dangerous in its DLLMain()
|
||
|
|
function. It seems to be caused by the new "side-by-side" C runtime dlls
|
||
|
|
(msvcr80.dll or msvcr90.dll being loaded multiple times by a .NET application
|
||
|
|
that uses msvcr??-linked native dlls).
|
||
|
|
To fix this issue, one of the following work-arounds could be used:
|
||
|
|
a) use an unzip32.dll that was linked against the system msvcrt.dll (the
|
||
|
|
"old" MSVC 6.0 runtime) that is a core system component of all Windows
|
||
|
|
versions from Windows 98/Windows ME and Windows 2000 and newer (at least
|
||
|
|
up to Windows Vista/Windows Server 2008),
|
||
|
|
or
|
||
|
|
b) use a statically linked variant of unzip32.dll (see the option DLLSTANDALONE
|
||
|
|
in the MSC Makefile for Win32 executables, "win32/Makefile").
