// This is a the source module that implements the stuff for saving to a
// self-extracting Zip archive.
//
// ZipFile is set up as a "partial class" - defined in multiple .cs source modules.
// This is one of the source modules for the ZipFile class.
//
// Here's the design: The self-extracting zip file is just a regular managed EXE
// file, with embedded resources. The managed code logic instantiates a ZipFile, and
// then extracts each entry. The embedded resources include the zip archive content,
// as well as the Zip library itself. The latter is required so that self-extracting
// can work on any machine, whether or not it has the DotNetZip library installed on
// it.
//
// What we need to do is create the animal I just described, within a method on the
// ZipFile class. This source module provides that capability. The method is
// SaveSelfExtractor().
//
// The way the method works: it uses the programmatic interface to the csc.exe
// compiler, Microsoft.CSharp.CSharpCodeProvider, to compile "boilerplate"
// extraction logic into a new assembly. As part of that compile, we embed within
// that assembly the zip archive itself, as well as the Zip library.
//
// Therefore we need to first save to a temporary zip file, then produce the exe.
//
// There are a few twists.
//
// The Visual Studio Project structure is a little weird. There are code files
// that ARE NOT compiled during a normal build of the VS Solution. They are
// marked as embedded resources. These are the various "boilerplate" modules that
// are used in the self-extractor. These modules are: WinFormsSelfExtractorStub.cs
// WinFormsSelfExtractorStub.Designer.cs CommandLineSelfExtractorStub.cs
// PasswordDialog.cs PasswordDialog.Designer.cs
//
// At design time, if you want to modify the way the GUI looks, you have to
// mark those modules to have a "compile" build action. Then tweak em, test,
// etc. Then again mark them as "Embedded resource".

/// If it is non-empty, the SFX will execute the command specified in this
/// string on the user's machine, and using the extract directory as the
/// working directory for the process, after unpacking the archive. The
/// program to execute can include a path, if you like. If you want to execute
/// a program that accepts arguments, specify the program name, followed by a
/// space, and then the arguments for the program, each separated by a space,
/// just as you would on a normal command line. Example: program.exe arg1
/// arg2. The string prior to the first space will be taken as the
/// program name, and the string following the first space specifies the
/// arguments to the program.
///
///
///
/// If you want to execute a program that has a space in the name or path of
/// the file, surround the program name in double-quotes. The first character
/// of the command line should be a double-quote character, and there must be
/// a matching double-quote following the end of the program file name. Any
/// optional arguments to the program follow that, separated by
/// spaces. Example: "c:\project files\program name.exe" arg1 arg2.

///
/// If the flavor of the SFX is SelfExtractorFlavor.ConsoleApplication,
/// then the SFX starts a new process, using this string as the post-extract
/// command line. The SFX waits for the process to exit. The exit code of
/// the post-extract command line is returned as the exit code of the
/// command-line self-extractor exe. A non-zero exit code is typically used to
/// indicated a failure by the program. In the case of an SFX, a non-zero exit
/// code may indicate a failure during extraction, OR, it may indicate a
/// failure of the run-after-extract program if specified, OR, it may indicate
/// the run-after-extract program could not be fuond. There is no way to
/// distinguish these conditions from the calling shell, aside from parsing
/// the output of the SFX. If you have Quiet set to true, you may not
/// see error messages, if a problem occurs.

///
///
/// If the flavor of the SFX is
/// SelfExtractorFlavor.WinFormsApplication, then the SFX starts a new
/// process, using this string as the post-extract command line, and using the
/// extract directory as the working directory for the process. The SFX does
/// not wait for the command to complete, and does not check the exit code of
/// the program. If the run-after-extract program cannot be fuond, a message
/// box is displayed indicating that fact.
///
///
///
/// You can specify environment variables within this string, with a format like
/// %NAME%. The value of these variables will be expanded at the time
/// the SFX is run. Example: %WINDIR%\system32\xcopy.exe may expand at
/// runtime to c:\Windows\System32\xcopy.exe.

///
