Inno Setup - display warning page

Question

I'm using Inno Script Studio to build an installer, so far very successfully as Inno Setup is a great package. However, I want to add a warning page which is displayed when the user unchecks an important Task. I thought this would just be an easy check. After some Googling, I realised that this will require some Pascal scripting - something that I unfortunately have no knowledge of (evidence below)... ``` begin if not IsTaskSelected('ImportantTask') then WarningPage := CreateOutputMsgPage(wpSelectTasks, 'Caution', 'Please read the following important information before continuing.', 'You have not selected the ImportantTask option.

Use msgbox's instead wizard pages. Msgbox's are especially used for Giving any indication(info,warning..etc) to user.. This script works as per your requirement.

```
[Setup]
AppName=MySetup 
AppVersion=1.5
DefaultDirName={pf}\MySetup 
[Tasks]
Name: "ImportantTask"; Description: "This task should be selected"; GroupDescription: "Important tasks";
[Code]
function NextButtonClick(CurPageID: Integer): Boolean;
begin
  Result := True;
  if (CurPageID = wpSelectTasks) and not IsTaskSelected('ImportantTask') then
    Result := Msgbox('You have not selected the ImportantTask option.' + #13#10 + 
      'Are you sure you want to continue ?', mbInformation, MB_YESNO) = IDYES;
end;
```
