We recently took on a new and exciting challenge from a startup client that expanded our portfolio into the realms of Laravel (a PHP framework), MySQL, and the Guesty Open API. This client, a forward-thinking startup, had developed a groundbreaking platform for property asset management, opening up a world of possibilities for property owners. With this platform, users can effortlessly register and oversee all assets, whether owned or loaned, across their entire property portfolio. The comprehensive management suite encompasses asset and inventory management, warranty tracking, maintenance and service history, task scheduling and tracking, document management, and end-of-life alerts. Our innovative platform finds its ideal application in various sectors, including hotels, gyms, multi-family houses, apartment complexes, office and commercial buildings, churches, and residential properties.

Our mission was clear: help our client build an additional module that seamlessly integrates their system with Guesty (guesty.com). Guesty, a powerful platform designed to supercharge hospitality operations, offers a range of features that simplify the management of rental properties. Property owners can now streamline their business operations, automation, and organization, all from a single platform.

The primary objective was to establish a robust connection between both platforms using Guesty’s Open API, which includes the following key features:

1. Properties Synchronization: This feature ensures that all properties registered for a particular user in Guesty are automatically transferred to their Property Assets Management system account.

2. Calendar Synchronization: With this functionality, users can view property booking dates in the Property Assets Management system’s calendar and efficiently plan service and maintenance schedules. Furthermore, any dates set in the calendar are synchronized back to Guesty, marking the property as unavailable for booking during those periods.

3. Messaging Integration: Guesty boasts an internal messaging system that allows guests to submit requests, complaints, and recommendations to property owners. We seamlessly integrated this system with the Property Assets Management platform, ensuring that messages could be handled appropriately.

In addition to these enhancements, we undertook several bug fixes and improvements to enhance the existing billing, invoicing, and internal messaging functionalities.

While delving into Laravel was a new experience for us, we quickly mastered it and successfully completed the project within the specified timeframe and budget. We found ourselves falling in love with the Laravel framework due to its simplicity, elegance, and remarkable power. It equips developers with all the necessary tools to construct robust and exceptional web applications.

We have a customer who is using SharePoint Online and they recently asked us to find a solution for the following situation in the Documents library.

There are a couple of root-level folders which are shared with specific user groups using a special permission level which doesn’t allow the users to delete those parent folders. However, the customer needs to allow the users to create new sub-folders and also delete them. The problem is that the sub-folders automatically inherit the permission settings of their parent folder which doesn’t allow the delete operation. So, they need to automatically break the inheritance and set appropriate permissions for the new sub-folders.

We found that Microsoft Flow is a great tool which helped us to resolve this problem by automating the process of breaking the default permissions inheritance and setting the desired permissions in SharePoint.

In this particular request we need to programmatically break inheritance of permissions for a given file/folder. Also, we need to assign unique permissions for that file/folder. These operations could be performed programmatically by calling the SharePoint REST API. This is a secured API and all API calls should be authenticated and authorized. This authentication is based on access tokens.

We ran into some peculiarities while implementing the solution and that is why we decided to share our experience here.

Recently we had to build a mobile application and one of the requirements was to implement a corporate authentication for managing the user accounts. We think the approach that we used could be interesting and helpful in similar scenarios that is why we would like the share our experience.

The app that we built is simple and allows pulling and displaying some corporate information for authenticated users. Following are some details about the technologies that we used to build the app:

• Ionic – We used the Ionic framework to build the mobile app itself. Ionic is a great framework for building hybrid mobile apps. It is based on AngularJS and provides handful components and tools. The apps build with Ionic are easily distributed to iOS and Android devices.
• ASP.NET Web API – We used the ASP.NET Web API 2.2 to build the server part. It pulls the data from the database and sends it to the mobile app in JSON format by implementing a RESTFul API. It also handles the authentication part by implementing part of the OAuth 2.0 protocol.
• Okta – Okta is a third-party authentication provider and our client had already been using it for managing their Active Directory accounts.

In short, the mobile app sends the credentials to the API server which is responsible to validate them by communicating with Okta. Once the credentials are validated then it generates a token which is stored on the mobile device and used for further communication between the mobile app and the API server.

TinyMCE is a great HTML editor and it is pretty easy to install and configure the editor on a web page. You should just call the init() function while loading the web page at the client’s browser and the target text-area will be transformed into a nice looking HTML editor.

However, we run into some troubles when we tried to use the TinyMCE editor on an ASP.NET page containing server inputs that are handled by the Microsoft’s UpdatePanel control.

Recently, we were asked to implement an online technical documentation solution by one of clients. We had to move the existing offline documents (mainly MS Word and PDF files) to an online accessible format that would also allow the users to modify the documents by themselves. We thought about the following options for implementing this:

• Implement a custom web based ASP.NET solution, starting from scratch
• Use Wiki engine
• Use CMS (e.g. WordPress)

We did not choose the custom implementation because it was the most time consuming option. We also did not choose the Wiki software because we found it a bit outdated and too restrictive and finally we focused on the CMS solution.

One of the projects on which we are working is a long-lived ASP.NET Web Forms system that is customized for a specific client. It is hosted by another company on a server which is external to the client’s environment and it does not have an access to the client’s internal network. The system is built by using the Form Authentication mechanism to authenticate and authorize the users. The list of users and their hashed passwords is stored into the database and the login functionality works in a classic manner – the credentials provided by the user on the login page are validated against the list of users in the database. If the provided credentials are valid then a new Forms Authentication session is established by calling the standard method FormsAuthentication.SetAuthCookie().

Recently, we had to extend that authentication mechanism by adding a single sign-on (SSO) capability which allows the client to integrate the ASP.NET web application with their internal Active Directory (AD) infrastructure. The requirement was to allow some internal employees to access the ASP.NET web application through SSO, but also keep the exiting database login functionality for the rest of the users who are external and they do not have internal AD accounts.

The ASP.NET web application is hosted on an external server and it does not have a direct access to the secured AD infrastructure. After doing some research, we found that in order to connect the external ASP.NET web application to the internal AD environment we can use a middle service called Security Token Service (STS).

HTML 5 – The Offline Challenge

I. Introduction

Some time ago our team had to add a new feature to one of our web projects. There was a request to add a capability to allow the users to use the application in “offline” mode. It was a great opportunity to dive into HTML 5 and more specifically the “offline” part of it. The new features of HTML5 are pretty interesting, but also “tricky” and this is why I would like to share some of the challenges we met.

First, I would like to say a few words about the technology on which the project is build. That is ASP.NET application which is storing data in SQL Server database. This is not a public application and only authorized users can access it. The system allows the users to go through their business process by entering the information in some structured web forms and at the end it allows them to generate a Word document, which is their final product. The web application is completely client-orientated and there is a huge usage of jQuery and AJAX. The AJAX calls are handled by WCF services. Frankly, this architecture made the implementation of the “offline mode” pretty straightforward.

Sending Email Messages with Embedded Images

Usually, when we implement email notification from various applications we send emails containing HTML body. And when there should be an image within the email body we put the image on a web server and use a reference to that image in the HTML code. Following as an example of this:

Hello world

 <img alt="sample image" src="http://webserveraddress/Images/sample_image.png" />

The drawback with this scenario is the need for connection to the web server when reading the email. This is causing issues, for example, when the server is part of an intranet network that is not always accessible by the clients. More
