我正在使用Inno设置来创建自定义安装程序，我需要在安装程序中添加一些内容。 通过此代码，我可以找到文件的最后修改日期，但我想在运行安装程序时将文件名作为输入。 看到这里
GetFileAttributesEx（'C：\ Users \ Gangadhar \ Desktop \ white_plain.gif'，GetFileExInfoStandard，FileInformation）;
在这个函数中，我将filename作为参数传递。我希望在运行安装程序时选择此文件名，就像选择目标文件夹向导一样，然后将选定的文件名作为参数传递给上面的函数。
任何帮助将不胜感激。 提前致谢

您正在寻找GetOpenFileName功能，该功能会显示一个对话框，使用户可以选择现有文件。以下脚本显示了当用户离开欢迎页面时如何显示此对话框。如果用户取消文件选择，他们将保留在欢迎页面上：
[Code]
function NextButtonClick(CurPageID: Integer): Boolean;
var
FileName: String;
begin
// allow users to go through the wizard by default
Result := True;
// if the user is going to leave the welcome page, then...
if CurPageID = wpWelcome then
begin
// set the initial file name
FileName := '';
// open the file dialog; if the user cancels it, they will stay at
// the welcome page (I don't know if it's your intention though)
Result := GetOpenFileName('Select the file to check', FileName, '',
'GIF Files (*.gif)|*.gif|All Files|*.*', '');
// if the user selected a file, then do whatever you want with it
if Result then
begin
// you got the file name in FileName variable
end;
end;
end;
