使用 FileCopy 功能在 Inno Setup Pascal 代码中安装文件（不是在向导表单上显示安装）

Question

How to copy a file using FileCopy function to the application folder, so that it's name does not display on the installing page? ( FilenameLabel ).

Ie I want to use the first option of Inno Setup - How to hide certain filenames while installing? (FilenameLabel)

Answer 1

Use the FileCopy function in the CurStepChanged event function :

[Files]
Source: "MyProg.exe"; Flags: dontcopy

[Code]

procedure CurStepChanged(CurStep: TSetupStep);
begin
  { Install after installation, as then the application folder exists already }
  if CurStep = ssPostInstall then
  begin
    Log('Installing file');
    ExtractTemporaryFile('MyProg.exe');
    if FileCopy(
         ExpandConstant('{tmp}\MyProg.exe'), ExpandConstant('{app}\MyProg.exe'),
         False) then
    begin
      Log('File installed.');
    end
      else
    begin
      Log('Failed to install file.');
    end;
  end;
end;
