1. Imported Win32 API calls - you must use .net api.
2. Hungarian notation - read .net sdk documentation. You should use different style of code. Microsoft provide lot recomendations for naming.
3. lot of Set* functions -> In C# you must use properties.
4. .net API has systembrushes. It's bad style to create your own
5. and _many_ other defects.
final result: 1.0
p.s. sorry for english, my C++ language is much better

hi. Yeah, that is much better ... but there some improvements.
1. I think _all_ font properties and variables should be removed, because RichControl has Font property.
(VS Designer can modify property with type Font)
2. m_crColor & backcolor vars & properties should be removed - use ForeColor & BackColor from RichControl
3. Remove GetStockObject - RichControl have DefaultFont property.
4. m_hwndBrush = new SolidBrush(SystemColors.Control);
-> must be changed to SystemBrushes.Control;
5. BrowsableAttribute is true by default - don't need to publish that every time... 
6. in all cases "new Pen(SystemColors.xxx)" should be replaced with "SystemPens.xxx"
7. from Paint:
switch (m_border)
{
[skip]
}
... look in2 msdn for ControlPaint class (it can be found by text search)
8. I don't like winapi in net. Replace ShellExecute, please

Hey Mike, what about doing at least one useful thing in your life like posting an article yourself, heh? That way we all can see how beautiful is your coding style (sigh) so we can have a little laughs here 
|
|

Hi Mike,
I am work on a project to building a blak box trading system
for a 400 person securities trading firm.
Do you know of any one who would like to work on this project.
Let me know.
Thanks.

I have to agree with mike, this is pretty horrid coding style. Why use C# when your going to import the Win32 API and use that? That pretty much defeats the purpose of .Net and C#.
While its nice to see that its possible to easily convert an MFC program to C#, I think this could have been done far better, by actually USING .Net and all that C# has to offer. Its no wonder this has such a low rating.
If you want to improove ratings, try making this a REAL .Net project and really use all that C# has to offer.
|
|
|
|
|
Considering this was done when .net was still beta one, i'd suggest you keep those type of comments to yourself.
BTW: this article are been superceded with the *built in* functionality offered by the .net framework.
|
|
|
|

I found the article to be really excellent. Not only provides some sample code on C# but also shows WinForms in action, and most importantly as the author pointed out, he found porting the code MFC to C#/.NET was simple, gives a relief
At the point where .NET is now such code deserves a 4+ definitely

Thanks Ranjeet
I will be posting revised sourcecode and a article to follow. I also will be posting ports from other MFC projects, so watch this section!
|
|
|
|
|
I thought it was good too - but I REALLY want to see a step by step on how you did it!
|
|
|
|

Hi, can any of you good gentlemen point me in the right direction (in terms of what to get/download from where) to get started using C#/.NET
Thanks

Try this link for the "NET Framework SDK Technology Preview" but beware its rather a large download 86Mb or 9x9.5mb chunks:
http://msdn.microsoft.com/downloads/default.asp
|
|
|
|
|
Everything I've heard also warns against installing the preview on a "production" development machine. Has anyone installed it on a machine that they use for day-to-day VC development? Any problems?
The things I have to have work:
-VC++
-Current Platform SDK and Win2k SP1 DDK
-Current MFC
The fact that I might easily break something has inclined me not to install the preview. Are these warnings I see more to cover MSFT's butt, or should they really be listened to?
Thanks,

I first installed the .NET preview on my "test" machine, I so no problems for about a week, so I installed on my live machine, I been using it for around 2 weeks and have had no problems as of yet - fingers x'ed.
BTW: I'm running VC++, Platform SDK etc.

I'd have to say I'm a little disappointed at the low rating. Is this a reflection on the brevity of the article, the code itself, or the fact that it's C# instead of C++?
I was ecstatic to get the first C++ -> C# conversion project, and I hope other authors follow suit.
cheers,
Chris Maunde

I guess it has to reflect C# as the original gets 4+/5 :
|
|
|
|
|
Chris
Maybe a if I wrote a step by step guide on how the code was ported, this would improve the ratings 
I thought by submitting the first article, would spur other programmers into doing the same.
|
|
|
|
|
That would be good. BTW which did you prefer as a finished product?
Kind regards
Al.
ATL, whomever that is, all the way
|
|
|
|
|
So what did you think about writing this code in C# using .NET? Can you describe how it compares to writing it in C++ with MFC?
Thanks,
Alvar
