what is the best and right way to patch a file in inno setup using xdelta

[Cesar82]

It is necessary to include XDelta3.dll in your installer.
You can create the code by copying parts of the code included in the DiskSpan GUI 2.0.0.2 example script.
ISxDeltaExtract only works if you create the patch using XDelta with the parameters:

MakePatch.bat

@echo off
set "OldFile=File_Old.txt"
set "NewFile=File_New.txt"
echo.
xdelta3.exe -e -9 -S djw -vfs "%OldFile%" "%NewFile%" "%OldFile%.diff"
echo.
echo.Press any key to exit.
pause >nul

thank you, the DiskSpan GUI 2.0.0.2 is a great example, but I think maybe its better for me to follow the original example of ISDone, because i want to use it on a simple inno setup script (nothing fancy)
but something that I still not sure about is how can I show the progress of it in installation page of my installer...

I Keep getting this error...
and I dont know why


here is the line of code

ExtractTemporaryFile('XDelta3.dll');
ISxDeltaExtract(0, 0, 0, 256000, ExpandConstant('{app}\test1.txt'), ExpandConstant('{tmp}\test1.txt.diff'), ExpandConstant('{app}\out3.dat'), false, false);

oh I think I made a big mistake...
what is the type of first argument of function? should I pass a compressed file to it??

ExtractTemporaryFile('XDelta3.dll');
ISxDeltaExtract(0, 0, 0, 640, ExpandConstant('{app}\test1.txt'), ExpandConstant('{tmp}\test1.txt.diff'), ExpandConstant('{app}\test_dest.txt'), false, false);

thank you again, but I still getting the same result...
I just using the ISDone.dll for the xdelta function, and im not using any other function

Make patch with parametters
xdelta3.exe -e -9 -S djw -vfs "%OldFile%" "%NewFile%" "%OldFile%.diff"

Tested with XDelta 3.0.11
Use the attachment to create the .diff file

thank you, I defiantly doing something wrong, here is my code

#define MyAppURL "http://www.example.com/"
#define MyAppExeName "MyProg.exe"

[Setup]

[-code]
function ISxDeltaExtract(CurComponent: Cardinal; PctOfTotal: Double; MinRAM, MaxRAM: Integer; InName, DiffFile, OutFile: AnsiString; DeleteInFile, DeleteDiffFile: Boolean): Boolean; external 'ISxDeltaExtract@{tmp}\ISDone.dll stdcall delayload';

procedure CurStepChanged(CurInstallStep: TSetupStep );
begin
  if (CurInstallStep = ssInstall) then
  begin
    ExtractTemporaryFile('XDelta3.dll');
    ExtractTemporaryFile('ISDone.dll');
    if ISxDeltaExtract(0, 0, 0, 640, ExpandConstant('{app}\File_New.txt'), ExpandConstant('{app}\*.diff'), ExpandConstant('{app}\test_dest.txt'), false, false) then Log('nice.');
  end;
end;

sorry for bother you so much and thank you

To display the progress I think it will be necessary to use the parameter "PctOfTotal" of the functions used.

Example patch 10% of progressbar.

if not ISArcExtract ( 0, 0.9, ExpandConstant('{src}\*.arc'), ExpandConstant('{app}'), '', false, '', '', ExpandConstant('{app}'), notPCFonFLY {PCFonFLY}) then break;

if not ISxDeltaExtract ( 0, 0, 0.1, 640, ExpandConstant('{app}\origfile.txt'), ExpandConstant('{app}\patch.diff'),   ExpandConstant('{app}\newfile.txt'), false, false) then break;
