Inno Setup从.ini读取值

Question

我想从.ini文件中读取值.然后写一个条件 - 如果这个值等于"1",那么做某事(执行一个动作).我尝试了getinistring,但我没有得到任何值(只显示默认值).我不知道如何在我下面的代码中实现readini.感谢您的帮助,IS初学者:)

//编辑这是一个代码:

#include ReadReg(HKEY_LOCAL_MACHINE,'Software\Sherlock Software\InnoTools\Downloader','ScriptPath','');
#include ReadReg(HKEY_LOCAL_MACHINE,'Software\Sherlock Software\InnoTools\Tray','ScriptPath','');

a :string;
b :string;

//Downloading a component depending on component choice in another setup(read from .ini)
procedure CurStepChanged(CurStep: TSetupStep);
begin
a:=GetIniString('Select', 'First', 'false', '{pf}/SP_Settings.ini');
b:=GetIniString('Select', 'Should', 'true', {pf}\SP_Settings.ini');

begin
if CompareStr(a,b)=0 then
  if CurStep=ssInstall then begin
      isxdl_SetOption('title', 'File Download');
      isxdl_SetOption('label', 'Download');
      isxdl_SetOption('description', 'Setup is downloading a file.');
      isxdl_Download(0,'url', ExpandConstant('{app}\x.rar'));   
      end;      
end;
end;

有Pascal脚本函数,GetIniInt或者GetIniString您可以用来从ini文件中读取.请参阅此参考.

我想请注意,我在OP改变他的问题之前写了这个回复,告诉我们他已经尝试了GetIniString和ReadIni功能.是的:在写这个答案之前我确实读过这个问题:-)

从您发布的代码中我可以看到您正在尝试从Program Files文件夹中读取ini文件.但是,这仅在使用该ExpandConstant函数时有效,因此应该阅读

a:=GetIniString('Select', 'First', 'false', ExpandConstant('{pf}') + '\SP_Settings.ini');
b:=GetIniString('Select', 'Should', 'true', ExpandConstant('{pf}') + '\SP_Settings.ini');
