ASP.NET (C#) Question

How do I create an IIS application and application pool using Inno Setup script

I'm trying to deploy an ASP.NET application using Inno Setup.

I need to perform the following tasks:


  1. Create an IIS application.

  2. Create a new IIS application pool and set it's .NET version to 4.

  3. Set the application pool of the new application to the new application pool.



I have found a script to create a virtual directory, but I need an application and application pool:

procedure CreateIISVirtualDir();
var
IIS, WebSite, WebServer, WebRoot, VDir: Variant;
ErrorCode: Integer;
begin
{ Create the main IIS COM Automation object }

try
IIS := CreateOleObject('IISNamespace');
except
RaiseException(
'Please install Microsoft IIS first.'#13#13'(Error ''' +
GetExceptionMessage + ''' occurred)');
end;

{ Connect to the IIS server }

WebSite := IIS.GetObject('IIsWebService', IISServerName + '/w3svc');
WebServer := WebSite.GetObject('IIsWebServer', IISServerNumber);
WebRoot := WebServer.GetObject('IIsWebVirtualDir', 'Root');

{ (Re)create a virtual dir }

try
WebRoot.Delete('IIsWebVirtualDir', 'eipwebv4');
WebRoot.SetInfo();
except
end;

VDir := WebRoot.Create('IIsWebVirtualDir', 'eipwebv4');
VDir.AccessRead := True;
VDir.AccessScript := TRUE;
VDir.AppFriendlyName := 'Easy-IP Web Client';
VDir.Path := ExpandConstant('{app}');
try
VDir.AppPoolId := 'Classic .NET AppPool';
except
end;

VDir.AppCreate(True);
VDir.SetInfo();
end;

Answer

The question was asked a long time ago but maybe somebody will find this script for IIS6/IIS7 useful:

var
  global_AppCmdFilePath :String;
  global_IsIIS7 :Boolean;
  global_WebSites :SiteList;
  global_WebSiteName :String;
  global_vDir :String;
  global_AppCmdExitCode :Integer;

const
  IISServerName = 'localhost';
  IISApplicationPoolName = 'Test Pool';

  ERROR_NOT_FOUND = 1168;
  ERROR_NOT_SUPPORTED = 50;

  MD_APPPOOL_IDENTITY_TYPE_LOCALSYSTEM = 0;
  MD_APPPOOL_IDENTITY_TYPE_LOCALSERVICE = 1;
  MD_APPPOOL_IDENTITY_TYPE_NETWORKSERVICE = 2;
  MD_APPPOOL_IDENTITY_TYPE_SPECIFICUSER = 3;

  MD_LOGON_INTERACTIVE = 0;
  MD_LOGON_BATCH = 1;
  MD_LOGON_NETWORK = 2;
  MD_LOGON_NETWORK_CLEARTEXT = 3;

function ExecAppCmd(params :String) :Boolean;
var
  execSuccessfully :Boolean;
  resultCode :Integer;
begin
  execSuccessfully := Exec('cmd.exe', '/c ' + global_AppCmdFilePath + ' ' + params, '', SW_HIDE, ewWaitUntilTerminated, resultCode);

  global_AppCmdExitCode := resultCode;

  Result := execSuccessfully and (resultCode = 0);
end;


function CreateVirtualDirectoryForIIS6(physicalPath :String) :String;
var
  IIS, webService, webServer, webRoot, vDir, vDirApp :Variant;
  appPools, appPool :Variant;
  webSiteId :String;
begin
  webSiteId := GetWebSiteIdByName(global_WebSiteName);

  { Create the main IIS COM Automation object. }
  IIS := CreateOleObject('IISNamespace');

  { Get application pools. }

    { Crete the application pool. }
    try

  try

    webRoot.SetInfo();
  except
    { An exception will be raised if there is not such a website. }
  end;

  { Create the virtual directory. }
  try
    vDir := WebRoot.Create('IIsWebVirtualDir', global_vDir);

    vDir.AccessRead := True;

var
  tempFileName :String;

      Exit;
    end;
  end;

  { Check if the application pool already exists. }
  tempFileName := ExpandConstant('{tmp}\AppPoolNames.txt');

  ExecAppCmd(Format('list apppool "%s" > "%s"', [IISApplicationPoolName, tempFileName]));

  if (LoadStringFromFile(tempFileName, appPoolList)) then
  begin
