InnoSetup pascal inheriting TControl causes identifier expected - inno-setup

I am trying to create my own InnoSetup Control (combined dropdown and file input box with browse button). I need dynamic number of these controls. My idea was to inherit TControl and build the needed control like that.
type
TConfigControl = class(TControl)
public
constructor Create(AOwner: TComponent);
end;
I am not avid Pascal programmer but I think the syntax should be correct. When I try to compile the InnoSetup script it gives "Identifier expected" to the second line.
On the other hand, is this the correct way to do this kind of thing in innosetup?

You can create your component in Delphi - regular Pascal allows you to do this.
Inno Setup Script cannot handle such situations (it is pretty complicated).
So develop plug-in (.dll file) and use it to place your control on Wizard's form.

Inno Setup: WizardForm from an external form

I was trying to create an installer for my new project and used an external DLL to call a function to create a custom form. Instead of using the WizardForm, can I create the WizardForm from that custom form?
Here's the code I use to create that form:
procedure NewFormCreate;
var
rt: TTimer;
begin
NewForm:= TForm.Create(nil);
NewForm.BorderStyle := bsNone;
CreateFormFromImage(NewForm.Handle, 'form.png');
rt:= TTimer.create(nil);
rt.OnTimer:= #WFProc;
rt.Interval:= 1;
rt.Enabled:= true;
NewForm.Show;
NewForm.Enabled:= False;
end;
If I understand your question correctly, you want to use your own implementation of the WizardForm.
You cannot. You can only modify the existing WizardForm. Maybe like this:
CreateFormFromImage(WizardForm.Handle, 'form.png');
You can of course create and display your own form, and prevent the WizardForm from even displaying.
But it does not make sense. The Inno Setup is all about the WizardForm. If you do not want to use it, you do not need the Inno Setup at all. Build your custom installer in Delphi (if that's your preferred IDE).
Maybe you should explain us what do you really want to achieve. It's quite probable that you have an XY problem.
Is your X problem creating an installer with irregular shape?
Instead of scripting everything manually you can use Graphical Installer for Inno Setup (http://graphical-installer.com/) and achieve something like this in few minutes:
If you use Delphi you can use RAD & Installer (http://rad-installer.com/) to create the Inno Setup installers directly from RAD Studio IDE.
Sorry for little self promo :)

Inno Setup: Disable specific Types from menu - similar to Components method previously posted

First I:
Searched a lot but did not find anything that seemed to cover this, but i might be missing it. (my coding sucks so I don't always know the right thing to search)
Scenario:
I like using the drop down list approach of selection more than the radio buttons or check boxes. So I typically add a Type for each component and disable component screen so the user just selects the appropriate option.
However I would like sometimes to check if a condition is met before offering the ability to select or reduce the list altogether.
What I did find:
For conditions I found this post Hide/Disable Component at runtime I tried it his way works but I would like to do the same thing but with Types.
Next?:
I cannot find if there is something like WizardForm.TypesList.ItemEnabled (I know that is not a real call)
Can this be done without building a fully custom types page? Also can it be a true hide? (disable works for me as well, hide is just cleaner)
To hide a setup type conditionally, use the Check parameter in the Types section.
[Types]
Name: "typeA"; Description: "A installation"
Name: "typeB"; Description: "B installation"
Name: "typeConditional"; Description: "Some other installation"; Check: CanInstallOther
[Code]
function CanInstallOther: Boolean;
begin
Result := ...;
end;
I do not think you can really disable an item of the drop down list. You can prevent a user from selecting it, but you cannot make it gray or something.

Changing label texts on WizardForm page in Inno Setup

I want to change (in code) the text of certain labels on the WizardForm of the installer which are NOT exposed by the WizardForm.
Example:
ReadyLabel2a=Click Install to continue with the installation, or click Back if you want to review or change any settings.
I cannot do WizardForm.ReadyLabel2a.Caption := 'BLAH'; as the compiler complains about unknown identifier ReadyLabel2a.
Is there a way to do it?
Thanks
All components of the installer wizard form are exposed.
The label is ReadyLabel, not ReadyLabel2a. The ReadyLabel2a is ID of the message. The installer uses either message ReadyLabel2a or ReadyLabel2b for the ReadyLabel, depending on the setup configuration.
WizardForm.ReadyLabel.Caption := 'BLAH';
See TWizardForm class declaration.
You can find how the messages are used in controls in Inno Setup source code
If you need to have an installer specific texts for certain standard messages, modify the texts using Messages section:
[Messages]
ReadyLabel2a=Click Install to continue with the installation, or click Back if you want to review or change any settings.

MFC SDI Application, how to change caption of menu item?

The whole day I am trying to solve this simple issue, but without any success.
I found a lot of hints in internet, but seems, that none of them is valid for my problem.
My issue is quite simple: I want to change the caption of a menue item while runtime
But it seems, that all solutions I found are very specific.
My requirements are this:
- it is a MFC application (VS2010)
- It is a SDI application, not MDI
- I want to change the caption of a main menu item (like "File"), not an entry of a submenue.
Because of main entry item, there is no ID for the menu item. Therefore solutions with ON_UPDATE_COMMAND_UI will not work!
My problems are:
- either the code I tried, is generating an assertion or exception
- or the function call returns with false
- or the function seems to work well, but I do not see any result (the caption is still unchanged)
Maybe I am using the wrong functions, or the wrong place for calling the functions.
Has anybody an example, which would work within my application pre-conditions?
Many, many thanks!

Windows cleverly hides the function to modify a menu under the arcane name of ModifyMenu. I hate it when they do things like that. Really makes me wish for Linux/Unix, with nice clear names like shmdt and mvwaddchnstr. Anyway, getting off my soap box for the moment, you'd call it something like this:
GetParentFrame()->GetMenu()->ModifyMenuW(1, MF_BYPOSITION, 0, L"New Item");
GetParentFrame()->Invalidate();

How execute code before which the Inno Select language dialog is shown

I need to execute a pascal code before that the Select Setup language Dialog is shown , unfortunately the InitializeSetup event is executed after.
function InitializeSetup(): Boolean; //This event occurs to late
begin
DoSomething();
Result := True;
end;
So it's possible execute a script code before of the Select Setup language Dialog is shown?
I had similar problem, and I thought about different workarounds: style all setup manually, or make inner localization, but they all looked so doomed from the beginning.
Select Setup language Dialog
I have forked issrc, built it locally, and looked at the main.pas of the Setup project. I see the idea behind doing as it is now : people may wanna use {Language} in InitializeSetup, so its called after the AskForLanguage method.
To just check the idea I made small changes to main.pas: call AskForLanguage after CodeRunner inited and InitializeSetup called. I got VCL'ed Select Setup Language dialog, but not all - NON Client Area wasnt VCL'ed:
I've tried to inherit the language form not from the TForm class but from the TSetupForm, or call it in the middle of setup or make other changes - with no result. If anybody know why it's not VCL'ed - tell me please!
Then I read the Custom Window Frame Using DWM article and just made the form border bsNone and got this:
So for now I'm fine with it. That form not styled before many pages of styled setup was so... annoying.
If we wanna do it a right way, I guess all that needs to be done - is moving CodeRunner init before AskForLanguage, and add a custom code function like StyleInit or so. Then all will be happy: {Language} will be available in InitializeSetup and Dialog will be VCL'ed.
No, the function InitializeSetup() is called as first.
All other functions are called later.
Of course you can modify Inno's sources and add custom functions but I think it is not your case.
Why do you need this? Maybe there is solution which can solve your situation, please tell us details.
Another possible solution is using Inno setup Ultra, it has several inprovements, and InitializeLanguageDialog function is one of them. just load style in it. (Also you can freely change language dialog itself that is so nice).
