inno-setup - 验证是否已安装，如果是则忽略一些文件

Question

仅当我对已安装的应用程序进行更新时，我才需要忽略一些文件(“.sdf”和“.config”)。

我递归地获取文件:

[Files]
Source: "..\..\bin\Release\MyApp.exe"; DestDir: "{app}"; Flags: ignoreversion
Source: "..\..\bin\Release\*"; DestDir: "{app}\"; Flags: ignoreversion recursesubdirs createallsubdirs; Permissions: everyone-full; Excludes: "*.key, *.udb, *.~db, *.crt"

以某种方式存在？

提前致谢。

答案 1

使用 onlyifdestfileexists 和 onlyifdoesntexist:

如果文件不存在 (onlyifdoesntexist)，请在第一次安装时复制您想要的所有内容。

如果文件存在(onlyifdestfileexists)，添加Excludes those extensions that you don't want to update.

Source: "..\..\bin\Release\MyApp.exe"; DestDir: "{app}"; Flags: ignoreversion
Source: "..\..\bin\Release\*"; DestDir: "{app}"; Flags: ignoreversion onlyifdoesntexist recursesubdirs createallsubdirs; Permissions: everyone-full; Excludes: "*.key, *.udb, *.~db, *.crt"
Source: "..\..\bin\Release\*"; DestDir: "{app}"; Flags: ignoreversion onlyifdestfileexists recursesubdirs createallsubdirs; Excludes: "*.key, *.udb, *.~db, *.crt, *.sdf, *.config"

答案2(未完全测试)

使用函数验证应用程序文件夹是否存在。

[Files]
Source: "..\..\bin\Release\MyApp.exe"; DestDir: "{app}"; Flags: ignoreversion
Source: "..\..\bin\Release\*"; DestDir: "{app}\"; Flags: ignoreversion recursesubdirs createallsubdirs; Permissions: everyone-full; Excludes: "*.key, *.udb, *.~db, *.crt";  Check: not IsInstalled
Source: "..\..\bin\Release\*"; DestDir: "{app}\"; Flags: ignoreversion recursesubdirs createallsubdirs; Permissions: everyone-full; Excludes: "*.key, *.udb, *.~db, *.crt, *.sdf, *.config";  Check: IsInstalled

[code]
function IsInstalled: Boolean;
begin
  if DirExists(ExpandConstant('{app}\')) then 
  begin
    Result := True;
  end else
    Result := False;
end;

在entry中添加Check参数，确保check函数在更新情况下返回false。下面是例子可以引用。

[文件]来源:“MyPROG.EXE”； DestDir: "{app}";检查:MyProgCheck
