Unable to obtain a list of IIS websites to allow user selection of setup location for use in an Inno Script setup, please help

Question

I am currently attempting to create an Inno script installer which requests a list of "Web sites" from a user's IIS installation so that the user can select the appropriate website from a combo box list and this list can be used to create a virtual directory in the correct Website location.

I need to Generate a list of IIS websites e.g. "Default Web Site" populating a combo box

So far I have only been able to achieve installing the virtual directory to a location based on a hard-coded combobox selection with the following code.

[Run]
Filename: {sys}\iisvdir.vbs; Parameters: "/create ""{code:GetWebSite}"" MyApp ""{app}\Website"""; Flags: skipifdoesntexist waituntilterminated shellexec; StatusMsg: Creating IIS Virtual Directory

[Code]
var
  WebsitePage: TWizardPage;
  ComboBox: TNewComboBox;

procedure InitializeWizard;
begin
  WebsitePage := CreateCustomPage(wpSelectComponents, 'Select which website you wish to install to',
'Which website should I install to?');
  ComboBox := TNewComboBox.Create(WebsitePage);
  ComboBox.Width := WebsitePage.SurfaceWidth;
  ComboBox.Parent := WebsitePage.Surface;
  ComboBox.Style := csDropDownList;
  ComboBox.Items.Add('Default Web Site');
  ComboBox.Items.Add('Website 1');
  ComboBox.ItemIndex := 0;
end;

function GetWebSite(Param: String): String;
begin
  { Return the selected Website }
  Result  := ComboBox.Text;
end;

All I need to do now is dynamically set the items from the available Websites that the user has in IIS...

Thanks for any help!

Actually I "solved" this yesterday, still haven't found anything else on this subject so I guess we are pioneers ;). I started a long the lines you did but I could not find any useful documentation and so went down another path. Although my solution works it is very messy.

Basically I run a VB script that outputs the list of web sites to a text file and then read that text file back into Inno setup. Below is my current code, which is very rough, I plan to tidy it up and add appropriate error handling later.

Website.vbs

OPTION EXPLICIT

DIM CRLF, TAB
DIM strServer
DIM objWebService
strServer = "localhost"

CRLF = CHR( 13 ) & CHR( 10 )

' WScript.Echo "Enumerating websites on " & strServer & CRLF
SET objWebService = GetObject( "IIS://" & strServer & "/W3SVC" )
EnumWebsites objWebService

SUB EnumWebsites( objWebService)
    DIM objWebServer, objWebServerRoot, strBindings

    Dim objFSO, objFolder, objShell, objTextFile, objFile
    Dim strDirectory, strFile, strText

    strFile = "website.txt"

    ' Create the File System Object
    Set objFSO = CreateObject("Scripting.FileSystemObject")

    If objFSO.FileExists(strFile) Then
       Set objFolder = objFSO.GetFolder(strDirectory)
    Else
       Set objFile = objFSO.CreateTextFile(strFile)
       ' Wscript.Echo "Just created " & strDirectory & strFile
    End If 

    set objFile = nothing
    set objFolder = nothing

    ' ForAppending = 8 ForReading = 1, ForWriting = 2
    Const ForAppending = 8

    Set objTextFile = objFSO.OpenTextFile _
    (strFile, ForAppending, True)

    FOR EACH objWebServer IN objWebService
        IF objWebserver.Class = "IIsWebServer" THEN

            SET objWebServerRoot = GetObject(objWebServer.adspath & "/root")

            ' Writes strText every time you run this VBScript
            objTextFile.WriteLine(objWebServer.ServerComment)

        END IF
    NEXT

    objTextFile.Close
END SUB
