FAQ: Are there any tools to convert my Delphi application code to a more modern language?

One of the questions we are frequently asked is whether you can use code conversion software to migrate a project from a legacy language to a modern language. This is coming up increasingly in relation to Delphi applications where despite the Delphi product’s continued endurance, resourcing support is becoming increasingly challenging and costly as time moves on.

The short answer to the question above is yes, there are tools to help convert Delphi applications to C#, most notably TurnSharp (by Collabratus) and Delphi2CS (by Netcoole). However, before taking this path, there are a few important things to consider about the potential migration of your application.

Considerations for migrating Delphi applications to modern programming languages such as C#.NET

1. How well written is the Delphi code of your application?

If you know the way your application code structured is poor, or even just outdated (e.g. highly procedural rather than object oriented) then using a code conversion as the basis for your new generation of software code would be very ill-advised.

2. What type of database/data access layer does your Delphi application use?

Many Delphi applications made use of the Borland Database Engine (BDE), a proprietary middleware layer provided with Delphi at the peak of its usage. Whilst TurnSharp does boast the ability to covert code that utilises the BDE, one also has to be aware that the BDE was designed primarily for file-based ISAPI database access. Therefore, many of the component types (e.g. TTable) would result in a very poor-performing application in a client/server database environment.

3. Does your application use 3rd party controls/components?

The success of code conversion tools depends on recognition of VCL (Visual Component Library) components to a great degree. Where a project uses 3rd party components or even custom components developed in-house or specifically for the project, the code conversion will be far less successful.

4. Does the functionality of the application model your business processes (or would you design the software differently with a “blank canvas”)?

Normally we find that applications written in legacy technologies will have a natural drop off in investment as a business looks forward to a replacement, reserving capital to commission the replacement project. Therefore, by the time the replacement project is commissioned, there are often a number of shortcomings with the application as a result of the fact it has not been kept in step with the way the business is operating. These will often result in manual workarounds and additional effort for key members of staff. The blank canvas approach provides much greater opportunity to address these issues.

5. Would your application benefit from being web based (in either a private intranet or public internet context)?

Nearly all Delphi applications we come across are Windows 32 bit client applications. There are a few ISAPI dll’s which drive websites and are built using Delphi, but these are in the minority and in most cases these would not convert at all well (because of their reliance on non-standard VCL components). Therefore one of the decisions that you will normally face when upgrading a Delphi application is whether a web based solution would suit better in the modern era. This is a particularly persuasive approach for most businesses as it eases deployment, makes remote and/or mobile access easier and modern browsers in conjunction with client side script allow a very rich user interface. So the question for a new development project is generally phrased the opposite way around, i.e. is there any compelling reason why the application cannot be web based?

When to use code conversion

You may have gathered by now that code conversion is not something that we would generally advocate, the only scenario in which I can see a good case for it is where you have developed a complex process represented by a well-structured code algorithm which has minimal user intervention and stores application data exclusively in memory rather than using a database, e.g. a file processing service. In that context, there would be a potential benefit of using code conversion.

Top five differences between SharePoint 2007 and SharePoint 2010


five differences between sharepoint 07 and 10 - Dec 11.jpg

SharePoint has been around since 2001 and is one of the top collaboration resources. However, it wasn’t until the SharePoint 2007 (known as Microsoft Office SharePoint Server 2007 or MOSS 2007) release that businesses really started to harness the power of collaboration. The latest 2010 version goes even further and offers sought after services straight out of the box.

So what is actually the difference between SharePoint 2007 and 2010? Well what a difference three years makes. This post looks at the key differences between SharePoint 2007 and the latest 2010 release and why SharePoint 2010 is what SharePoint 2007 should have been but wasn’t.

1. Improving social networking capability

A lot has changed in the World since 2007 and one of the biggest is the online explosion of social networking websites.

SharePoint 2010 has dramatically improved its capability in this arena with the addition of personal blogs, tagging and activity feeds within its social networking sites – MySites. MySites allow integration with Microsoft’s BCS (Business Connectivity Services), which allows IT to link employees’ MySites profiles to non-SharePoint data, such as information from a human resources system.

Wiki and blog integration in MOSS 2007 wasn’t great and was widely panned by experts for not being very user friendly. Usability has been a key focus for SharePoint 2010 and it has been dramatically improved.

Similarly, community interaction within SharePoint 2007 was pretty poor and has been given a helping hand with user interfaces similar to Facebook profile pages. SharePoint 2010 has also added keyword tagging so that content can be found quicker.

SharePoint 2010 is even following in Twitters footsteps by adding micro blogging and activity feeds into the service.

2. Improved search and content management

The search function in SharePoint 2010 is far more superior to previous versions because of improved scalability, query functionality and index redundancy.

As for managing business content, Microsoft has removed limitations in MOSS 2007’s Enterprise Content Management (ECM) feature so document libraries can grow to 200 million items.

3. Working offline

SharePoint 2010 makes up some ground on the likes of Lotus Notes with SharePoint Workspace. Workspace makes SharePoint libraries, lists and forms accessible offline. This is a huge step forward and helps to improve the productivity and efficiency of the users.

4. Better connection to line-of-business data

Previous versions of SharePoint have had difficulties when trying the access enterprise software systems. Microsoft has made significant improvements to integrate more business data in SharePoint 2010 by using its BCS (Business Connectivity Services) suite.

A recent Forrester report cited that the BCS helps make SharePoint 2010 the “connective tissue that bridges line-of-business systems and knowledge worker systems”. The previous iteration of BCS, called BDC (Business Data Catalog), could bring only line-of-business data into SharePoint. BCS will provide both read and write access between business applications and SharePoint 2010.

5. Developing SharePoint Apps

Improvements to the design tool SharePoint Designer means that developer will need to deal less with coding. Tighter integration between Visual Studio and SharePoint, and built-in support for Silverlight is a great improvement on its predecessor MOSS 2007.
