Create Virtual Directory

Invalid Parameters

Entry In IIS

Introduction

As per the name, it's easy to guess what this project is all about, creating a virtual directory in the default web site (80). The program uses the IIS Administration SDK, which has the Active Directory Service Interfaces (ADSI) that helps VC++ to access the required functions and interfaces.

Background

I started looking on the net for similar programs that uses ADSI with VC++, but was not able to find one, so thought of creating one.

Using the code

To access the ADSI functions, we need to have the following header files.

// The basic header files used
iads.h
adshlp.h
iiisext.h
iisext_i.c

// Constant used to access the default port 80 
// We take IIS://localhost/w3svc/1/Root
// as the path to access the default web site 
const LPWSTR adsPATH = L"IIS://localhost/w3svc/1/Root"; 

IDispatch *pDisp = NULL; //Idispatch interface object
IADs* iAds = NULL; //Active Directory Interface 
IADsContainer* iContainer = NULL; //Active Directory Container Interface 
IISApp *pApp = NULL; //Active Directory IIS Application interface 

Access the ADSI object

//Get Object of  Active Drectory Container ADsGetObject(adsPATH, 
IID_IADsContainer,(void **)&iContainer);

Creating a virtual directory

hr = iContainer->Create(L"IIsWebVirtualDir", cAppName,  &pDisp);

Creating the application with the use of QueryInterface

hr = iAds->QueryInterface( IID_IISApp, (void **)&pApp  );

Accessing the virtual directory property using the iAds interface

hr = iAds->Put(L"AccessRead",CComVariant(VARIANT_TRUE));    
hr = iAds->Put(L"AccessWrite",CComVariant(VARIANT_TRUE));    
hr = iAds->Put(L"AccessScript",CComVariant(VARIANT_TRUE));    
hr = iAds->Put(L"AppIsolated",CComVariant(1));    
hr = iAds->Put(L"EnableDirBrowsing",CComVariant(VARIANT_TRUE));    
hr = iAds->Put(L"AppFriendlyName",CComVariant(cAppName));
hr = iAds->Put(L"Path",CComVariant(clPath)); //Virtual Dir Physicial Path    

Update the changes to the ASDI objects

hr = iAds->SetInfo();
//Save Virtual Dir Application Information

Linking issues

You might end up in getting a link error. To solve this,s the following libraries need to be included:

Activeds.lib 
Adsiid.lib

The currently supported languages are: C++.

Points of interest

While trying out lots of options, I had to interpret .NET code and transform it in to VC++, and one thing I found is whatever the language is, you just need a vision to make it work.
