Inno Setup Skip custom page after execution of some scripts - inno-setup

Question

so i am currently trying to modify the setup script,
What i was trying to do was after installing i enter in a custom page, this custom page executes 2 scritps(one for creating the database and the other for creating the tables).
while this is executing i want to display a custom label,and a continuous progress bar.
When the execution finish, i want to go directly to the finish page.
I wanto to also remove the next button.
Is this possible?
For the moment i have the custom page with a constinuous progress bar, this page appears after install.i will then add the label after finishing the progress bar part.
here is my code:
[CODE]
var
Page: TWizardPage;
ProgressBar3: TNewProgressBar;
procedure CreateTheWizardPages;
begin
Page := CreateCustomPage(wpInstalling, 'Base de dados', 'A verificar a base de dados');
ProgressBar3 := TNewProgressBar.Create(Page);
ProgressBar3.Left := 5;
ProgressBar3.Width := Page.SurfaceWidth - 5;
ProgressBar3.Parent := Page.Surface;
ProgressBar3.Style := npbstMarquee;
end;
procedure InitializeWizard();
begin
CreateTheWizardPages;
end;
//check the current page,if page equals to wpSelectCompnets, then we add the method on choose to the combobox fo types of installation
procedure CurPageChanged(CurPageID: Integer);
begin
//msgbox(IntToStr( CurPageID),mbInformation, MB_OK);
if CurPageID = wpSelectComponents then
begin
comboboxTypesInstalacao:=WizardForm.TypesCombo;
WizardForm.TypesCombo.OnChange:=#ComboBoxChange;
end
else if CurPageID = Page.ID then
begin
try
CreateDBAndTables('idontimedb.des');
finally
//close this custom wizard page and go to finish page
end;
end;
end;
Thanks in advance.
