Inno Setup提示您输入外部文件 [英] Inno Setup Prompt for external file location

问题描述

我当前使用[Files] Flags: external将用户数据导入到我的安装中，正在运行.

I currently use [Files] Flags: external to import user data into my installation, which is working.

我现在需要在安装过程中提示您输入特定的外部文件.

I now need to prompt for a specific external file during the installation.

用例:
我们安装需要许可证文件的软件(请勿与许可证协议混淆).我想提示用户输入他们的许可证文件.他们提供文件后，会将其复制到DestDir.

Use case:
We install software that requires a license file (not to be confused with the license agreement). I want to prompt the user for their license file. Once they provide a file, it would be copied to the DestDir.

我正在寻找类似[Files] Flags: PromptForFile之类的东西或实现相同目的的例程.有人已经解决了吗?

I'm looking for a something like [Files] Flags: PromptForFile or a routine that achieves the same. Has someone already solved this?

推荐答案

使用 CreateInputFilePage函数转到创建自定义向导页面，以提示用户输入许可证文件.

Use the CreateInputFilePage function to a create custom wizard page to prompt a user for the license file.

然后，使用脚本常量，将所选路径用作[Files]部分中的源路径.

Then, use a scripted constant to use the selected path as a source path in the [Files] section.

[Files]
Source: "{code:GetLicensePath}"; DestDir: "{app}"; Flags: external

[Code]

var
  LicenseFilePage: TInputFileWizardPage;

procedure InitializeWizard();
begin
  LicenseFilePage :=
    CreateInputFilePage(
      wpSelectDir,
      'Select License File Location',
      'Where is your license file located?',
      'Select where License file is located, then click Next.');

  LicenseFilePage.Add(
    'Location of license file:',         
    'License files|*.lic|All files|*.*', 
    '.lic');                             
end;

function GetLicensePath(Param: string): string;
begin
  Result := LicenseFilePage.Values[0];
end;

TODO:您需要以某种方式处理用户没有选择任何许可证文件的情况.要么不允许继续(请使用 NextButtonClick )或跳过文件安装(使用 Check参数).

TODO: You need to handle somehow a situation, when a user does not select any license file. Either don't allow to proceed (use the NextButtonClick) or skip the file installation (use the Check parameter).
