I have made an installer for my program with Inno Setup and it has been worked fine so far,
but it gives error in one system : (The system is Win7-64 bit)
SWbemServicesEx: Generic failure
The code is :
WbemLocator := CreateOleObject('WbemScripting.SWbemLocator');
WbemServices := WbemLocator.ConnectServer('.', 'root\CIMV2');
QueryGPU := 'SELECT * FROM Win32_VideoController';
WbemObjectSet := WbemServices.ExecQuery(QueryGPU);
if not VarIsNull(WbemObjectSet) then
begin
NetworkAdapter := WbemObjectSet.ItemIndex(0);
uuG := NetworkAdapter.PNPDeviceID;
end;
The error occurs at this line:
WbemObjectSet := WbemServices.ExecQuery(QueryGPU);
The problem has been resolved after removing Graphic driver. I think graphic driver didn't allow to run query.

Can you create a custom page that looks like the Finish page?
This is the code for custom page,
UserPage2 := CreateCustomPage(
UserPage1.ID,
'Title',
'Details'
);
This custom page,
Needs to look like this,
The reason for this is because, sometimes when the user runs the installer again they will be able to select few options. Based on the options the installer needs to make few changes to the settings used by the installed program without overwriting the files by reinstalling. So the user should get the Finish dialog after the changes.
Recreate the FinishedPage controls on your custom page.
When entering the page, you need to resize WizardForm.InnerNotebook to cover whole wizard window (except for the bottom button area) and hide the page header controls.
var
FakeFinishedPage: TWizardPage;
FakeFinishedBitmapImage: TBitmapImage;
FakeFinishedLabel: TNewStaticText;
FakeFinishedHeadingLabel: TNewStaticText;
procedure CopyBounds(Dest, Source: TControl);
begin
Dest.Left := Source.Left;
Dest.Top := Source.Top;
Dest.Width := Source.Width;
Dest.Height := Source.Height;
end;
procedure FakeFinishedPageActivate(Sender: TWizardPage);
begin
WizardForm.Bevel1.Visible := False;
WizardForm.MainPanel.Visible := False;
WizardForm.InnerNotebook.Left := 0;
WizardForm.InnerNotebook.Top := 0;
WizardForm.InnerNotebook.Width := WizardForm.OuterNotebook.ClientWidth;
WizardForm.InnerNotebook.Height := WizardForm.OuterNotebook.ClientHeight;
// With WizardStyle=modern and/or WizardResizable=yes,
// we cannot copy the sizes in InitializeWizard as they are not final yet.
CopyBounds(FakeFinishedBitmapImage, WizardForm.WizardBitmapImage2);
FakeFinishedBitmapImage.Anchors := WizardForm.WizardBitmapImage2.Anchors;
CopyBounds(FakeFinishedLabel, WizardForm.FinishedLabel);
FakeFinishedLabel.Anchors := WizardForm.FinishedLabel.Anchors;
CopyBounds(FakeFinishedHeadingLabel, WizardForm.FinishedHeadingLabel);
FakeFinishedHeadingLabel.Anchors := WizardForm.FinishedHeadingLabel.Anchors;
WizardForm.BackButton.Visible := False;
WizardForm.NextButton.Caption := SetupMessage(msgButtonFinish);
end;
procedure CopyLabel(Dest, Source: TNewStaticText);
begin
Dest.AutoSize := Source.AutoSize;
Dest.Font := Source.Font;
Dest.ShowAccelChar := Source.ShowAccelChar;
Dest.WordWrap := Source.WordWrap;
end;
procedure InitializeWizard();
var
S: string;
begin
// ...
FakeFinishedPage := CreateCustomPage(UserPage1.ID, '', '');
FakeFinishedPage.OnActivate := #FakeFinishedPageActivate;
FakeFinishedBitmapImage := TBitmapImage.Create(WizardForm);
FakeFinishedBitmapImage.Parent := FakeFinishedPage.Surface;
FakeFinishedBitmapImage.BackColor := WizardForm.WizardBitmapImage2.BackColor;
FakeFinishedBitmapImage.Bitmap := WizardForm.WizardBitmapImage2.Bitmap;
FakeFinishedBitmapImage.Stretch := WizardForm.WizardBitmapImage2.Stretch;
FakeFinishedLabel := TNewStaticText.Create(WizardForm);
FakeFinishedLabel.Parent := FakeFinishedPage.Surface;
CopyLabel(FakeFinishedLabel, WizardForm.FinishedLabel);
S := SetupMessage(msgFinishedLabelNoIcons) + #13#13 + SetupMessage(msgClickFinish);
StringChangeEx(S, '[name]', 'My Program', True);
FakeFinishedLabel.Caption := S;
FakeFinishedHeadingLabel := TNewStaticText.Create(WizardForm);
FakeFinishedHeadingLabel.Parent := FakeFinishedPage.Surface;
CopyLabel(FakeFinishedHeadingLabel, WizardForm.FinishedHeadingLabel);
S := SetupMessage(msgFinishedHeadingLabel);
StringChangeEx(S, '[name]', 'My Program', True);
FakeFinishedHeadingLabel.Caption := S;
end;
There are some limitations:
The code does not handle correctly image resizes, when the wizard resizes (with WizardResizable=yes) – it's easy to fix though.
The solution does not expect that any page will be shown after this fake finish pages shows. I.e. there's no Back button and it's expected that the Finish button is implement to kill the intallater. After all, this is a follow up question to Conditionally skip to a custom page at the end of the Inno Setup installation wizard without installing?
Though to avoid all these hacks, consider allowing the installation to proceed normally, but without changing anything. It might be easier to implement in the end.

I already used InfoBeforeFile directive, with an "Important notice" text file.
But I would prefer the user could continue to read the instructions throughout an installation (e.g. in a separate window).
Any clue?
Added the final result, thanks again to Martin Prikryl
Use CreateCustomForm function to create a separate window for your message.
[Files]
Source: "important.txt"; Flags: dontcopy;
[Code]
procedure InitializeWizard();
var
InfoForm: TSetupForm;
InfoMemo: TRichEditViewer;
begin
InfoForm := CreateCustomForm;
Log(IntToStr(WizardForm.Left));
Log(IntToStr(WizardForm.Width));
InfoForm.Left := WizardForm.Left + WizardForm.Width;
InfoForm.Width := ScaleX(400);
InfoForm.Caption := 'Important message';
InfoForm.Top := WizardForm.Top;
InfoForm.Height := WizardForm.Height;
InfoForm.Position := poDesigned;
InfoForm.Show();
InfoMemo := TRichEditViewer.Create(InfoForm);
InfoMemo.Parent := InfoForm;
InfoMemo.Left := ScaleX(40);
InfoMemo.Top := ScaleX(40);
InfoMemo.Width := InfoForm.ClientWidth - 2 * ScaleX(40);
InfoMemo.Height := InfoForm.ClientHeight - 2 * ScaleX(40);
InfoMemo.ScrollBars := ssVertical;
InfoMemo.ReadOnly := ssVertical;
InfoMemo.WantReturns := ssVertical;
InfoMemo.WantReturns := False;
ExtractTemporaryFile('important.txt');
InfoMemo.Lines.LoadFromFile(ExpandConstant('{tmp}\important.txt'));
end;
Though, wouldn't it be better to display the message on the side of the installer wizard?
I got a code from List all physical printers using WMI query in Inno Setup and I want to add the results to a list box. I have tried to do it before asking, but I just can't add all items. This is an my code:
var
Query, AllPrinters: string;
WbemLocator, WbemServices, WbemObjectSet: Variant;
Printer: Variant;
I: Integer;
begin
WbemLocator := CreateOleObject('WbemScripting.SWbemLocator');
WbemServices := WbemLocator.ConnectServer('.', 'root\CIMV2');
Query := 'SELECT Name FROM Win32_Printer';
WbemObjectSet := WbemServices.ExecQuery(Query);
if not VarIsNull(WbemObjectSet) and (WbemObjectSet.Count > 0) then
begin
for I := 0 to WbemObjectSet.Count - 1 do
begin
Printer := WbemObjectSet.ItemIndex(I);
if not VarIsNull(Printer) then
begin
Log(Printer.Name);
AllPrinters := Printer.Name;
end;
end;
end;
end;
Then on a custom page do this:
ListBoxPrinters.Items.Add(AllPrinters);
You add the items (printers) to the list box the same way, the original code adds them to the log: in the loop!
for I := 0 to WbemObjectSet.Count - 1 do
begin
Printer := WbemObjectSet.ItemIndex(I);
if not VarIsNull(Printer) then
begin
ListBoxPrinters.Items.Add(Printer.Name);
end;
end;
Of course, you have to create the custom page with the ListBoxPrinters before iterating the printers.
If you cannot run the query after creating the page for whatever reason, you can store a printer list into TStringList.
var
Printers: TStringList;
Printers := TStringList.Create;
for I := 0 to WbemObjectSet.Count - 1 do
begin
Printer := WbemObjectSet.ItemIndex(I);
if not VarIsNull(Printer) then
begin
Printers.Add(Printer.Name);
end;
end;
And once you have the list box ready, you just copy the list over to the box:
ListBoxPrinters.Items.Assign(Printers);
You overwrite always with the next AllPrinters := Printer.Name; the previous value !
simple build the AllPrinters string like that
....
AllPrinters := '';
....
for I := 0 to WbemObjectSet.Count - 1 do
begin
Printer := WbemObjectSet.ItemIndex(I);
if not VarIsNull(Printer) then
begin
Log(Printer.Name);
AllPrinters := AllPrinters + Printer.Name + #13#10;
end;
end;
end;
and
ListBoxPrinters.Items.Text := AllPrinters;
I'm trying to get the list of physical printer's name, that are connected to Windows, based on an answer from Query available RAM in Inno Setup.
But just get: "Send To OneNote 16".
Here is my query:
Query := 'SELECT Name FROM Win32_Printer';
Printer := WbemQuery(WbemServices, Query);
if not VarIsNull(Printer) then
begin
Log(Format('Printers=%s', [Printer.Name]));
end;
You have to iterate the result set:
var
Query: string;
WbemLocator, WbemServices, WbemObjectSet: Variant;
Printer: Variant;
I: Integer;
begin
WbemLocator := CreateOleObject('WbemScripting.SWbemLocator');
WbemServices := WbemLocator.ConnectServer('.', 'root\CIMV2');
Query := 'SELECT Name FROM Win32_Printer';
WbemObjectSet := WbemServices.ExecQuery(Query);
if not VarIsNull(WbemObjectSet) and (WbemObjectSet.Count > 0) then
begin
for I := 0 to WbemObjectSet.Count - 1 do
begin
Printer := WbemObjectSet.ItemIndex(I);
if not VarIsNull(Printer) then
begin
Log(Printer.Name);
end;
end;
end;
end;
The code requires Unicode version of Inno Setup (the only version as of Inno Setup 6) for a better Variant support.
Actually, you can see this code in the same question, where you took the WbemQuery from:
Is there a way to read the system's information in Inno Setup
Note how the Win32_NetworkAdapterConfiguration is iterated there.
I made a custom wizard page, and I want it to show a sort of installation checklist at the end of the install, showing what installed successfully or not.
Something like
Crucial Step......................SUCCESS
Optional Step.....................FAILURE
So I have this code in my initializeWizard()
Page := CreateCustomPage(wpInstalling, 'Installation Checklist', 'Status of all installation components');
RichEditViewer := TRichEditViewer.Create(Page);
RichEditViewer.Width := Page.SurfaceWidth;
RichEditViewer.Height := Page.SurfaceHeight;
RichEditViewer.Parent := Page.Surface;
RichEditViewer.ScrollBars := ssVertical;
RichEditViewer.UseRichEdit := True;
RichEditViewer.RTFText := ''// I want this attribute to be set in CurStepChanged()
Is there a way to add or edit RichEditViewer.RTFText at a later point in time? Page is a global variable but trying to access any attributes gives me an error. I'd like to do edit the text after wpInstalling, so I can tell whether or not install steps were successful.
I'm not a huge fan of this method, but you Can set your RichEditViewer as a global, and then editing it at any point, in any function, is trivial.
var
RichEditViewer: TRichEditViewer;
procedure InitializeWizard();
var
Page: TWizardPage;
begin
Page := CreateCustomPage(wpInstalling, 'Installation Checklist', '');
RichEditViewer := TRichEditViewer.Create(Page);
RichEditViewer.Width := Page.SurfaceWidth;
RichEditViewer.Height := Page.SurfaceHeight;
RichEditViewer.Parent := Page.Surface;
RichEditViewer.ScrollBars := ssVertical;
RichEditViewer.UseRichEdit := True;
end;
procedure CurStepChanged(CurStep: TSetupStep);
begin
if CurStep=ssPostInstall then RichEditViewer.RTFText := 'STUFF';
end;
Worthwhile to note, the page itself doesn't even need to be global.
