Mono Vs. VB Pro Features
May 31, 2011
I 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?

I've heard a lot about Mono but I have no idea what exactly it is or how to use it. All I know is it's aimed at making .NET apps cross platform. Could someone tell me or point me to some tutorials explaining how to port my vb code to run on other operating systems? Maybe shed some light on all of this?

I started a new solution (with multiple projects) and am trying to get it to build. Initially I was getting an internal compiler error and thought maybe it had to do with MySql, so I removed all references to MySql. Now I am getting the error "Could not find a 'Sub Main' in ''". I have made sure that all of my projects have a Main subroutine like this:Public Shared Sub Main()End Sub2 out of the 7 projects will compile. I don't know what makes these projects different from the others, and the error message isn't very helpful. Any experience with this one?

I've downloaded latest source from mono project, compiled it and everything works (c# projects, mod_mono, xsp) except vb.net. Vbnc, mono's vb.net compiler does not exist after compiling mono from source.This is on CentOS 5, on Ubuntu 10.04 I installed mono packages via apt-get and vb.net just works.

I read many questions on running .net code with mono but i always end up with the same question. I'm building a new app right now, so i better start straight and take the good direction: Can i develop an app within Visual C# Express or Visual Basic Express, compile it from the Microsoft environment using the compilers they have and run that application using MONO on linux.Or do i have to work with the mono compiler from scratch (or convert my MS project afterwards to mono) to be able to use my .net apps using the Mono framework on linux.Linux/Mac support is not really a must for my app development, but i'd like to get it straight off the start.i'm using WinForms, Encryption, Globalization, SQLClient but thats probably all, is there anything you Mono experts out can tell me NOT to use off the start.Oh and i use the My namespace for all sorts of things such as getting the computer name, logged on user name, resources, settings, etc...

Someone asked me today if it was possible to port a visual basic application to Linux or similar platform, I assumed it was .NET so I suggested to use Mono, but noticed that on their vb support page they only talk about vb 8 (.NET) Does mono support non-.NET vb? In fact I'm not sure what he is using, I think vb6, I'm not sure of the versioning at all though.

Is it possible to play 8 different and individual mono wave files to a 7.1 (8 channels) audio system using vb.net? (I undestand that the .1 speaker is the subwoofer and I'm not yet sure it can be replaced with an ordinary speaker.) The playing should start simultaneously and the files can be of different size/length.Is this something that should be done using win API functions if it can be accomplished at all.I just re-installed my old VB6 which I need to ugrade and vb.net would be the easiest for me so I placed this Q here.

To do some testing with MPIR, GMP, the .Net Bigint module and other math libraries I've recently written a small program which allows me to create random sequences of numbers with a certain amount of precision: Always this amount of digits in front and behind the comma, no starting/ending zeroes. While it might not be the most elegant of code, it really blew my mind when I found out my application was running up to 10 times faster with Mono under Ubuntu 10.10.While the code is not elegant and in Basic, it was developed by me in about an hour's work and it serves the purpose: To generate dependable huge datasets consisting solely of preconfigured numbers before or after the comma. To get a general idea the UI's posted here:[code]Eliminating IO by not writing to IO but just to a List instead Eliminating an "if" path which checks if the random before/after float character is checked.Disabled progress reporting in general which causes the backgroundworker to not report any progress.Play around with the amount of symbols, theres very little difference between just getting 1 random character or getting 15 per record.I'm at a loss to what causes my program to run so slow under Windows/.Net compared to Ubuntu/Mono. I'm only a "half programmer", which means: I'm a Bussiness and ICT student who mainly focusses on human ICT, and the Microsoft Platforms certainly have lead on that, however such a huge performance hit compared to Linux for this soul and simple program really gives me a cold chill when it comes to my favourite platform.

I am exposing some ISO C++ data types to .Net (mono on Linux to be precise).For the purpose of brevity, I shall refer to C# in my question, although my question relates to all of the .Net languages (with C# and VB.Net being my target languages). So far, I have worked out how to expose the ISO C++ data types in C# class(es) for use in mono -The only problem so far is how to deal with the C++ callbacks. In .Net languages (C# and Vb.Net), I believe 'delegates' are the callback equivalent.
Sticking with C# for now, can anyone recommend a way that I can register the C# delegate functions with my ISO C++ code.The ISO C++ code is a notification library, and I want to be able to "push" the notifications to the mono framework (i.e. C# delegates in this case).My underlying assumption is that the mechanism/steps to implement this would be the same for the .Net languages - I'll just have to code the actual delegates in the .Net language of choice - is that assumption correct?Last but not the least, is the question of thread saftey. The underlying ISO C++ code that I am exposing to .Net (mono to be more specific), is both re-ntrant and thread safe - do I have to do anything "extra" to call .Net delegate from my ISO C++ code?

After rewriting a VB.NET assembly with Mono.Cecil the 'Call Stack' debugging window in Visual Studio 2010 shows the language as C# and not VB.NET. Is it possible configure Mono.Cecil to rewrite an assembly so the debugger recognises the rewritten assembly as VB.NET?The following Mono.Cecil simply reads and saves an assembly without modification. However, the debugger reads the new assembly as C# instead of VB.NET.
Dim readerParameters = New ReaderParameters() With {.ReadSymbols = True}
Dim writerParameters = New WriterParameters() With {.WriteSymbols = True}
[code]....
It is desirable for the rewritten assembly to be VB.NET so the debugging windows 'Local' and 'Immediate Window' are the VB.NET versions rather than the C# versions.

I had a look through the documentation on the Wiki, but it seems a bit thin. How do I determine if a type implements a given interface using Cecil? For my particular implementation it is important that I do not actually load the type into the AppDomain.m Here's the code that I have so far:
Dim outputModule As ModuleDefinition = ModuleDefinition.ReadModule(outputFile)
For Each assemblyType As TypeDefinition In outputModule.Types

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 ?

I 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.

I like the new intellisense enhancements for finding members, however, there are 2 problems i have;
1) You can't resize the intellisense window when it pops up? This one is really annoying.
2) There seems to be a fixed font for the intellisense list? Why does it not match the rest of my code window like it used to? I've noticed the same with tooltips.

I am looking for a way to obtain some additional features on a treeview. Both, to show as to be able to input some data with a particular hierarchical structure For that on each node I need next to the nodetext a entrypossibility to input some data or to make a selection. This input possibility should be either a textbox, a combobox or a chechbox. An example of what I wisch is almost this article, except that the comment column is only a fixed text, and that I need there a input control like a textbox, or combobox.
