In interface-based programming we normally define a set of functions inside an interface, and use that interface as a contract between 2 or more modules.What happens when we need to add more features to the system?How do we handle such system evolutions ?
View 2 RepliesI am thinking of giving mono develop a try. I have some questions. Visual Studio 2008 Professional has options for creating controls and services. This is not available in Visual Basic 2008 Express. This relationship between the different editions, is there something limiting like this with mono develop? I figure since it's open source, everything is implemented like Visual Studio 2008 Pro.
Another question. Does anyone have experience with mono. Is it a production level serious environment for commercial work? Is there something I should know about it?
Any mono developer that has anything good or bad to say, please drop a post in here. I would like to get as much info as possible from vbforums. This has always been the best help site for me using Visual Basic Express.
The most important thing, to reiterate is if I can make Windows Services with Mono Develop and if it supports full threading features that are limited or not available in express.
As a last question, what is the story on managed directx for mono. On Linux, there is no such thing, so would you plan an opengl library to start with? or does that work out in a different way?

View 2 RepliesI have a large .NET source tree (185 C# and VB projects, of which 60 are apps or websites) that i want to create a wix setup for. The general idea is to have 1 setup msi and to make each executable a feature, and to have each app be installed in a separate directory. like
%progfiles%/company/app1
/app2
/app3
[code].....
Some libraries are used by multiple apps, so the DirectoryRef would have to be pointing to multiple directories, and multiple DirectoryRefs (with different ids) would have to be pointing to the same directory (found directory alias trick), both of which seem impossible.I get the distinct impression I'm going about it the wrong way, or that I'm missing some deeper insight. (No suprise as my wix-fu is a full 3 days old)

I even have it set up so I can filter through the DataGridView by sorting though a specific company in the database. However, now I want to link specific cells from the DataGridView to other VB features such as a text box and check box. I am a bit lost as to the coding. In the DataGridView, there are numerous columns that contain a check box and I need them to correlate to actual check boxes I have in the form. I can do it through binding the check box on the form to the data source and it works but if I run a filter or sort through the company, the check boxes from the DataGridView no longer carry over to the actual check box on the page.

I actually found a fairly good pong tutorial on this site which I've linked to at the bottom of this post. I used the code as my base and I'm starting to implement my own new features. I'm currently working on making the ball move faster after each hit of the paddle, but I can't get it working! I thought it would be as simple as adding 1 to the 'speed' variable during the test to see if the ball has hit the paddle. Doesn't work! I also tried various other methods, including adding an extra timer to the form and having the speed increase a certain number every tick on the timer. Didn't work! Is there some special way that I need to reference that variable in order to manipulate it? Code below.

Is there any way to use the new dynamic features in the 4.0 framework like ExpandoObject in VB.NET without setting Option Strict Off? With C#, you lose type safety only with the variables you specifically declare as dynamic. But with VB, the only way I've found to use these features is with the old Option Strict Off trick that's been in VB.NET since the beginning. Without Option Strict, everything in the file is polluted with fuzzy typing like so:
Option Explicit On
Option Strict Off
Option Infer On
[code]....
what's the best way to still use things like ExpandoObject and mitigate the risk of losing all type safety? Partial classes?
