Reading archive:
Extract to path:
with CreateInArchive(CLSID_CFormatZip) do
begin
OpenFile('c:\test.zip',',',');
ExtractTo('c:\test',',',');
end;
Get file list:
with CreateInArchive(CLSID_CFormat7z) do
begin
OpenFile('c:\test.7z',',',');
for i := 0 to NumberOfItems - 1 do
if not ItemIsFolder[i] then
Writeln(ItemPath[i],',',');
end;
Extract to stream
with CreateInArchive(CLSID_CFormat7z) do
begin
OpenFile('c:\test.7z',',',');
for i := 0 to NumberOfItems - 1 do
if not ItemIsFolder[i] then
ExtractItem(i, stream, false,',',');
end;
Extract "n" Items
function GetStreamCallBack(sender: Pointer; index: Cardinal;
var outStream: ISequentialOutStream): HRESULT; stdcall;
begin
case index of ...
outStream := T7zStream.Create(aStream, soReference,',',');
Result := S_OK;
end;
procedure TMainForm.ExtractClick(Sender: TObject,',',');
var
i: integer;
items: array[0..2] of Cardinal;
begin
with CreateInArchive(CLSID_CFormat7z) do
begin
OpenFile('c:\test.7z',',',');// items must be sorted by index!
items[0] := 0;
items[1] := 1;
items[2] := 2;
ExtractItems(@items, Length(items), false, nil, GetStreamCallBack,',',');
end;
end;
Open stream
with CreateInArchive(CLSID_CFormatZip) do
begin
OpenStream(T7zStream.Create(TFileStream.Create('c:\test.zip', fmOpenRead), soOwned),',',');
OpenStream(aStream, soReference,',',');
...
end;
Progress bar
function ProgressCallback(sender: Pointer; total: boolean; value: int64): HRESULT; stdcall;
begin
if total then
Mainform.ProgressBar.Max := value else
Mainform.ProgressBar.Position := value;
Result := S_OK;
end;
procedure TMainForm.ExtractClick(Sender: TObject,',',');
begin
with CreateInArchive(CLSID_CFormatZip) do
begin
OpenFile('c:\test.zip',',',');
SetProgressCallback(nil, ProgressCallback,',',');
...
end;
end;
Password
function PasswordCallback(sender: Pointer; var password: WideString): HRESULT; stdcall;
begin// call a dialog box ...password := 'password';
Result := S_OK;
end;
procedure TMainForm.ExtractClick(Sender: TObject,',',');
begin
with CreateInArchive(CLSID_CFormatZip) do
begin
// using callback
SetPasswordCallback(nil, PasswordCallback,',',');
// or setting password directly
SetPassword('password',',',');
OpenFile('c:\test.zip',',',');
...
end;
end;
Writing archive
procedure TMainForm.ExtractAllClick(Sender: TObject,',',');
var
Arch: I7zOutArchive;
begin
Arch := CreateOutArchive(CLSID_CFormat7z,',',');
// add a file
Arch.AddFile('c:\test.bin', 'folder\test.bin',',',');
// add files using willcards and recursive search
Arch.AddFiles('c:\test', 'folder', '*.pas;*.dfm', true,',',');
// add a stream
Arch.AddStream(aStream, soReference, faArchive, CurrentFileTime, CurrentFileTime, 'folder\test.bin', false, false,',',');
// compression level
SetCompressionLevel(Arch, 5,',',');
// compression method if <> LZMA
SevenZipSetCompressionMethod(Arch, m7BZip2,',',');
// add a progress bar ...
Arch.SetProgressCallback(...,',',');
// set a password if necessary
Arch.SetPassword('password',',',');
// Save to file
Arch.SaveToFile('c:\test.zip',',',');
// or a stream
Arch.SaveToStream(aStream,',',');
end;
