Chilkat.Zip zip = new Chilkat.Zip();

bool success;

//  Any string unlocks the component for the 1st 30-days.
success = zip.UnlockComponent("Anything for 30-day trial");
if (success != true) {
    MessageBox.Show(zip.LastErrorText);
    return;
}

//  Initialize the zip object.  Because we're creating
//  a self-extracting EXE in this example, the filename
//  passed to NewZip will never actually be created.
success = zip.NewZip("notUsed.zip");
if (success != true) {
    MessageBox.Show(zip.LastErrorText);
    return;
}

//  Append a directory tree.  The AppendFiles does
//  not read the file contents or append them to the zip
//  object in memory.  It simply appends references
//  to the files so that when WriteExe (or WriteZipAndClose,
//  or WriteZip, etc.) is called, the files are compressed
//  and added to the archive.
bool recurse;
recurse = true;
zip.AppendFiles("c:/temp/a/*",recurse);

//  Indicate that when the EXE is run, it should automatically
//  extract to a temp directory.
zip.AutoTemp = true;

//  If you want the EXE to self-extract with no user-interface,
//  add this:
zip.ExeNoInterface = true;
zip.ExeSilentProgress = true;
zip.ExeWaitForSetup = false;

//  Indicate that after extracting, a setup program should be run:
zip.AutoRun = "setup.exe";

//  Pass these command line params to the AutoRun program:
zip.AutoRunParams = "-a -b -c";

//  Write "mySfx.exe"

success = zip.WriteExe("mySfx.exe");
if (success != true) {
    MessageBox.Show(zip.LastErrorText);
    return;
}

MessageBox.Show("EXE Created!");
