Is there a way to make a listener (code, etc) that listens to get file size in an inno setup? My goal is to show progress in nanozip. It will listen to the nanozip output file with a time interval and get to the rate of total file size to the current size.

Is there a way to detect the amount of CPU threads / cores there are and do something accordingly?

Eg.

if CPU_THREADS = 6 then
begin
do_stuff
end else begin
do_other_stuff
end;

Asking because some multithreading tools crash when dealing with 6 or 12 threads.

So I would put if GetSysCores = 6 in the if loop after calling the function?

As the function returns an integer value I think I can use it directly without declaring variables.
if GetSysCores = 6 then
begin

end;

The function can also be simplified using variables of type variant so you can get any supported value just by changing the string you want to search for.

function GetSysInfo(const WMIClass, WMIProperty: String): Variant;
var
  WbemLocator, WbemServices, WbemObjectSet, WbemObject: Variant;
begin;
  WbemLocator := CreateOleObject('WbemScripting.SWbemLocator');
  WbemServices := WbemLocator.ConnectServer('localhost', 'root\CIMV2');
  WbemObjectSet := WbemServices.ExecQuery('Select ' + WMIProperty + ' from ' + WMIClass);
  if (not VarIsNull(WbemObjectSet)) and (WbemObjectSet.Count > 0) then begin
    WbemObject := WbemObjectSet.ItemIndex(0);
    if not VarIsNull(WbemObject) then
      Result := WbemObject.Properties_.Item(WMIProperty).Value;
  end;
end;

procedure GetFreeMemory(var Free, Total: Extended);
begin
  Total := GetSysInfo('Win32_OperatingSystem', 'TotalVisibleMemorySize');
  Free := GetSysInfo('Win32_OperatingSystem ', 'FreePhysicalMemory');
end;

function CPUCores: Integer;
begin
  Result := GetSysInfo('Win32_Processor', 'NumberOfCores');
end;

function CPUThreads: Integer;
begin
  Result := GetSysInfo('Win32_Processor', 'NumberOfLogicalProcessors');
end;

You can also use the API if you prefer to get Threads.

type
  TSystemInfo = record
    wProcessorArchitecture: Word;
    wReserved: Word;
    dwPageSize: DWORD;
    lpMinimumApplicationAddress: Integer;
    lpMaximumApplicationAddress: Integer;
    dwActiveProcessorMask: DWORD;
    dwNumberOfProcessors: DWORD;
    dwProcessorType: DWORD;
    dwAllocationGranularity: DWORD;
    wProcessorLevel: Integer;
    wProcessorRevision: Word;
  end;

procedure GetSystemInfo(var lpSystemInfo: TSystemInfo);
  external '[email protected] stdcall delayload';

function GetCPUThreads: Integer;
var
  SysInfo: TSystemInfo;
begin
  GetSystemInfo(SysInfo);
  Result := SysInfo.dwNumberOfProcessors;
end;

Has anyone had an installer made using inno setup just soft-lock consistently? Trying to unpack an archive but it consistently gets stuck on this one file, refusing to progress any further, the funny thing is though, no error codes are displayed, the applications "elapsed time" function continues to run, with CPU & Disk utilisation dropping to 0%, I'm honestly stumped on this one.

This appears an issue with the decompressor you are using and not inno setup itself.

Ah grim, well that narrows it down to 2 issues then. Fingers crossed I can get it working! I have a feeling it might be due to the assets I ripped, was a bit messy with ripping shit.

Just as a preface, I originally posted this in the "ASIS" thread, but I reckon it might be more applicable here.

So I have a handful of repacks which have selective installs for a collection of titles, with each having its own shortcut to be placed on the users Desktop, should they select this as an option. Currently however, regardless of the end-users selection a shortcut for each entry made for the application is placed on the desktop, even if the target file is not present. It's not a critical issue but it is a slight annoyance.

My proposed solution, as detailed below, was to use a function named "RemoveShortcut", which is used for the uninstaller generated for a given install, as can be seen here:

[UninstallDelete]
Type: filesandordirs; Name: {app}
#sub RemoveShortcut
  #emit "Type: Files; Name: ""{userdesktop}\" + Trim(ReadIni(SourcePath + "\Settings.ini", "Executable" + Str(i), "ShortcutName", "")) + ".lnk"";"
  #emit "Type: Files; Name: ""{userprograms}\" + Trim(ReadIni(SourcePath + "\Settings.ini", "Settings", "ShortcutName", "")) + "\" + Trim(ReadIni(SourcePath + "\Settings.ini", "Executable" + Str(i), "ShortcutName", "")) + ".lnk"";"
#endsub
#for {i = 1; Trim(ReadIni(SourcePath + "\Settings.ini", "Executable" + Str(i), "ShortcutName", "")) != ""; i++} RemoveShortcut

However this doesn't seem to work, with testing of 2 dummy data files (each housing its own target application, as well as a blank file to be used as a indicator that the selected component was present), demonstrating both shortcuts were removed even when installing only one of the selected components. If anyone has any thoughts on this I'd love to hear them. I initially thought I might be able to use a series of batch scripts instead, with one script for the removal of each component to be run post-install present in a "main" data file, with a given components archive having an identical, but blank script to overwrite the valid script, however I found I wasn't able to consistently CD to the userdesktop, since I didn't initially take into account a user having a desktop location at a location outside of their C: drive.

ORIGINAL QUESTION:


Hi all,

Got a small question regarding whether my proposed solution could work at all (I'm terribly new to pascal/delphi). I've got a fair few packs that feature selective, multiple-title offerings to the end-user, each with their own, separate executable to launch from (since some are emulated and require a small script to launch the ROM), as well as their own entry under the shortcut section of the "Settings.ini" file used in ASIS (baked into a executable thats just a batch script wrapped in an exe). My issue is that regardless of the component selection, upon extraction of all selected archives, all desktop shortcuts defined within the "settings.ini" are generated (should the option be selected).

My current thought process is using the "RemoveShortcut" function, in the Post-install section of the script to delete the shortcut, if a given .txt file is missing (which would be packed with a given selective offering), like so:

    
#if ("{app}\_CommonRedist\APPS\APP_1.txt" == "0") && ("{userdesktop}\APP_1.lnk" == "1")
 #for {i = 1; Trim(ReadIni(SourcePath + "\Settings.ini", "Executable" + Str(i), "ShortcutName", "")) != ""} RemoveShortcut
#endif
#if ("{app}\_CommonRedist\APPS\APP_2.txt" == "0") && ("{userdesktop}\APP_2.lnk" == "1")
 #for {i = 2; Trim(ReadIni(SourcePath + "\Settings.ini", "Executable" + Str(i), "ShortcutName", "")) != ""} RemoveShortcut
#endif

However upon testing this both shortcuts were removed even when installing only one of the selected components. Does anyone have any idea why this might be?

I would like to know if anyone has a solution to my problem. I would like to display the thumbnail in the taskbar and at the same time include a checkbox to keep the installer window on top (over other windows) if the checkbox is checked. If I use the code from the page below to display the installer thumbnail on the taskbar the property "WizardForm.FormStyle" doesn't work.
Part of the code was obtained from: inno-setup-window-preview-in-taskbar

If anyone can help me, I appreciate it.
Below is a code to better understand my question.

[Setup]
AppName=My App
AppVersion=1.0
DefaultDirName={{#VER > 0x06000000 ? "common" : ""}pf}\My App
DisableWelcomePage=no
OutputBaseFilename=My_App
OutputDir=.

  GW_OWNER = 4;
  GWL_HWNDPARENT = (-8);

function SetWindowLong(Wnd: HWND; nIndex: Integer; dwNewLong: Longint): Longint; external '[email protected] stdcall delayload';

    WizardForm.FormStyle := fsNormal;
    ////SetWindowLong(WizardForm.Handle, GWL_HWNDPARENT, GetWindowLong(GetWindow(WizardForm.Handle, GW_OWNER), GWL_HWNDPARENT));
  end;
end;

procedure InitializeWizard();
begin
  ////OldParent := GetWindowLong(WizardForm.Handle, GWL_HWNDPARENT);

  OnTopCheckBox := TNewCheckBox.Create(WizardForm);
  with OnTopCheckBox do begin
    Parent := WizardForm;
    Caption := 'Keep On Top';
    SetBounds(ScaleX(10), WizardForm.NextButton.Top + ScaleY(2), ScaleX(100), ScaleX(15));
    OnClick := @OnTopCheckBox_OnClick;

  { work if disable this line }
  SetWindowLong(WizardForm.Handle, GWL_HWNDPARENT, GetWindowLong(GetWindow(WizardForm.Handle, GW_OWNER), GWL_HWNDPARENT));

Hi all.
Could you please help me with the following:
I have an installer for a mod, but if a person uninstalls a mod, the whole game is uninstalled as well.
How can I make it so that only the mod files are deleted?

I was thinking of keeping an install log and taking files from it to delete, but damn, that doesn't work right.
(It doesn't delete files from the list and it doesn't log small files)
I'll attach a sample code)

Thank you in advance.

Function InitializeUninstall(): Boolean;
begin
  ULog := FileExists(ExpandConstant('{app}\INSTALL.LOG')); // you need to get the log now, it might not exist later
  if ULog then // if there is a log file, create a sheet where we load the list of files
  begin
    unins_list := TStringList.Create;
    unins_list.LoadFromFile(ExpandConstant('{app}\INSTALL.LOG'));
  end;
  Result := True;
end;

Procedure CurUninstallStepChanged(CurUninstallStep: TUninstallStep);
  var
    i : Integer;
begin
  If CurUninstallStep = usPostUninstall then
    if ULog then
    begin
      for i := 0 to unins_list.Count-1 do DeleteFile(unins_list:[i]); // delete files from the list - It doesn't work
      unins_list.Free;
    end;
end;
