I realize this question has probably been asked and anwered already, but I'm am now ready to move from 6.0 to .NET. I want to continue with MFC and to ease myself into the .NET framework gradually. However, I am just curioes as to how much MFC has changed under .NET. Have they added a lot to it? Does moving into that environment buy that much for you? Or is it just as well to develope MFC apps with 6.0? In other words, is it just the same old MFC with a new wrapper?

MFC has new classes, CString is templatized.
New stuff in ATL.
Faster Compiler.
Better IDE - excepted for touching up resource images.
Real easy to import VC6.0 projects.
Around thumbs up.

Thanks. How about XML support in the new MFC? Is that there? I've been hacking around with some DOM and SAX2 stuff and basically thinking it sucks. Has that improved?
I'm trying to find some documentation but can't seem find so much as a class heirarchy chart.

Yeah I know what you mean. AFAIK the only XML support is thru the .NET framework, which mean you have to branch into some managed code.

Oh, well, I suppose I have to make the leap sometime. Thanks, again.

I have a couple of questions/concerns about GDI+.
I've seen a few people say that GDI+ was much slower than GDI. Messages were from October of last year, so I wonder if this have been improved in the final release of .NET (if it was updated at all)?
Also I am trying to figure out what is the deal with NULL pens (PS_NULL) in GDI+. I cannot seem to find anything about it. Do I just set my Pen* to NULL and do things like this:
if( pMyPen )
myGraphics.DoSomethingWithPen(pMyPen,...);
But it seems that executing if's in the loop will be much slower than passing a PS_NULL pen every once in the while. What am I missing here?
Thank you.

1/ I rewrote a GDI paint program in GDI+ prior to OCtober and had no speed issues.
2/ Make the pen a color with an alpha of 0 and it will be transparent.

Thank you Christian. (I was hoping you were hanging around here about this time  )
1. I need to render a ton (A TON = maybe hundreds of thousands of iterations) of 2D shapes as fast as I can. Do you think it will be comparable to GDI speedwise.
2. Cool. How come I did not think of that? *scratching head*

Even GDI is not good for real time stuff, that is why we have Direct Draw. The difference is if you use DD, you can build a GDI+ surface from DD directly, and vice versa, far more easily than using GDI.
As for the difference, I suspect there will be one, but not a huge one.

I have an app that can be extended by developing COM-Addins.
I can do this by creating an IDL and deploying a TLB. So, every customer can implement an interface and I create components at runtime by ProgID using CreateObject.
Ok, I assume there's something simillar (or even, better) in .NET. How do I do this in .NET ? I've seen something like Reflection or Remoting, but it seems too much trouble when compared to COM. Is there an easier way ?

Hai,
I am trying to install VS.NET final version. While installing, at first it says to setup Windows Component Update. But when I click the link in the wizard, it says, "Setup has detected that another program requires to reboot the machine. Click ok to reboot the machine and start setup again....".
I have rebooted my machine zillion times. But no luck. I keep getting the same message. I have uninstalled all my previous versions of .NET. Any idea why this occurs? Is there any registry settings that I can change so that this would let me go thru the installation.
Please help me. I have a project deadline to meet.

There is a readme.html file on disk1,about these troubleshooting.
I don't have those disks now to check them for you but I remember that
some other programs need to be uninstall too,so check that file.
(Do you have SQLSerever installed,maybe for it,just guess)

The three main things that VS.NET readme.html says about uninstalling are...
1. Uninstall any previous versions of VS.NET -- Yes I did. check.
2. Uninstall any previous versions of .NET framework -- Yep. check.
3. Stop .NET Framework Support service, if listed in Services -- I couldnt find it. So thats a check too.
Its still not working... Strange thing is. I opened up the moreinfo.htm file in the Windows Componenet Update. I read how to bypass this component update if you have all the updates in your machine. It also said, how to install individual components that are missing in your macine. Certain things were missing in my machine. One of them FP Server extensions 2000. So I went to the corresponding folder in the CD to run the installation. Guess what, it said, "This version of FrontPage Server extensions cannot run on Windows 2000 machines. Visit http://www.microsoft.com/frontpage/fpse for details. I did go there I found, FPSE 2002. Ok. Latest version. So I installed that on my machine. Now it asks me to install IE6.0. But when I try to install IE6.0 I get the same error message.
"Another program needs to reboot your machine to complete its setup process. Please reboot and run setup again".
What the heck is the problem?

So switch to task manager and terminate all processes that you think they are not neccessary,or uninstall all program that you think they are not important or you can uninstall them temporary.

Nope. No luck. 
I have uninstalled, SQL Server 2000 utilities, VB6.0, VI 6.0. I am only left with VS 6.0 (only VC in it). I can also go ahead and uninstall it. But do you think that could solve the problem??? I am a little skeptical!!!

Try running [CD-ROM]:\setup\Setup.exe /NO_BSLN_CHECK from Disk 1 (disable autorun or press shift while loading CD 1 into drive)
For example:
D:\setup\setup.exe /NO_BSLN_CHECK
This way, setup will run without running WCU.
Be sure to update your system using the standalone installers on the WCU disk

I read this suggestion from moreinfo.htm in the Windows Component Update CD. But I am not able to install IE6.0. Can I install it after installing VS.NET??

hmmm... I don't think so...
Not read anything about it, but it's so dependant on new MSXML features, the start screen is a IWebBrowser...

hey I got this workaround.
If you have certain problems in installing Windows Components update. Insert the Windows Component CD. Run the setup.exe in that CD. It would say "Setup has been started without starting VS.NET CD1" (or something like that) "Please click Yes and insert CD 1 or click No to continue with Windows Component installation which will install all components".
I said No, and fortunately it was able to find out what are the components that are missing and I installed all components successfully.
Then I inserted CD 1 and it automatically disabled the Windows Component Setup link and ready to install VS.NET....

One more additional information. MS did not specify about the size of the registry or the amount of registry values that it is planning to write. While installing my registry was filled up and it couldnt write any more registry values.
If you change your registry size in the middle of installation it will not be taken into effect until you reboot your machine. So check your size of registry, increase it if needed (atleast some more memory that VS.NET can feel free to write, not almost going to choke), reboot your machine and do the installation.

Does anyone know how to implement multi-selection inside a treeview the easy way. I probably have to design it myself, but it would be a great help of-course if someone knows where I can find some samples...
