MFC is actively maintained for Desktop development. The latest version MFC 14.10.25008.0 was released back in March 2017.
Of course everyone is encouraged to move towards adopting the modern Universal Windows Platform.

MFC14 is from VS2015 it only supports .Net 4.6 and later .NET 4.6.1
They patched a few dropdeads in it for the release of VS2017 so it supports .NET 4.6.2.
The history is clearly covered in Wikipedia if you need to reference:
Microsoft Foundation Class Library - Wikipedia[^]
You will note the major revision revision number has not changed from VS2015 to VS2017 on those releases unlike earlier situation and that is a direct consequence of no further development.
As we speak right now MFC is currently broken again under .NET 4.6.2 on Windows 10 after the anniversary update is applied and now .NET 4.7 has been released. It's been like that for months so lets see how long it takes them to fix and support 4.7 as an indication of the support for MFC. Note VS2017 auto updated and downloaded WPF changes so it was compatible with .4.7 basically two days after .NET 4.7 update was released and it made it into the advertising blurb (Announcing the .NET Framework 4.7 | .NET Blog[^])

If you mean what does Microsoft marketing want you to use to program desktop apps then the answer is C# with .Net that was the whole push with VS2017 you actually have to select to install C++ as an option with VS2017. I don't know how successful they were with it, there was considerable pushback at them over the C++ issue.
As a fulltime commercial programmer I have always programmed on the Windows API so it all means little to me because I would never waste my time supporting any of the frameworks they all come and go. Once you have you own library sets there is little attraction in any of the framework groups. So I really want nothing more than a functional C++ compiler with a good IDE and debugger which VS2017 has in spades.
I probably represent the problem for MS compiler marketing that they need to sell me something and there is very little I need from them 
Anyhow here is the Desktop Marketing blurb for C++ from VS2017 make of it what you will (but notice it's an option not the default install as is MFC within that)
Windows desktop development with C++ in Visual Studio | Visual C++ Team Blog[^]
I suspect somewhere down the track customers like me will end up using just the IDE with a linked compiler module. MS has an interesting community IDE called confusingly Visual Studio Code
Visual Studio Code - Code Editing. Redefined[^]
MS finally added C++ to Visual Studio Code compiling options late last year but it has several drawbacks to VS2017. The intellisense on it is not as developed as VS2017 and the compiler technology is very different and the code produced is not as efficient as VS2017.
It's also worth looking at the backdrop to the c++ compiler at MS which now stands apart from Visual Studio itself

The problem is glaringly obvious it's telling you the problem
You must have noticed the file path names... Microsoft visual studio 9 ... Microsoft visual studio 10.0
You either compile for VC9 or you Compile for VC10 what you can't do is mix and match the system files.
That means either
1.) Your project file incorrectly references both sets of VC base directories ... a big no no
2.) Some header directly includes the VCx files from the other system.
FIX IT .. CHOOSE 1 VERSION OF VC !!!!!!!
There is a fast haxx way which is to rename one of the VC base directory trees temporarily ... the compiler can't use what it can't find
It will either fix everything that means your project file is DORKED or it will spit it can't find xyz file and that will be the wrong VC directory so fix it.

Just about everyone who comes here uses Visual Studio on a daily basis. As stated by two other posters your project was in a mess, which was why you got that problem, but the information you originally provided did not show it up. In fact from your original question it was not possible to figure out what you were doing, hence my comments.

Hi,
Just a Comment.
I assume that you understand that each 'C' or 'CPP' File, gets compiled into One and only One '.obj' module.
The Linker stitches all those 'Obj' modules together, to create an Exe or DLL, your Target. In doing so, your program needs to link with other libraries and DLL's already on the system. For Instance, your program uses the keyboard, and uses the mouse. You did not have to write the code inside your program to track the mouse movements, register the clicks, etc. That was already done by Microsoft, and comes as part of the Windows Package. Now, Microsoft wrote all that stuff, but, the compiler needs to know what is available from Microsoft, I.e.: the function and other specifications that the Windows API provides. These specifications are included in the System Headers. If you change these specifications to suit your own purpose, well, it Might work if you also 'Re Compiled Windows'
If you mess with your system header files, you are actually telling your compiler that Windows works different than that it actually does.
Your Compiler caught you out, and stopped you writing a disaster.
include files do not make your program larger, at most it slows down your compiler and linker

No.
We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.
Try it yourself, you may find it is not as difficult as you think!
If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!

hello,
Can anyone help me out in writing large number of files(almost 8000) parallely in a directory using openMP support in VC++
I am also using a recursive function inside WriteFile to do the writng texts to the corresponding file
My code snippet is as below
===========================
#pragma omp parallel private(i)
{
#pragma omp for schedule(dynamic, 1)
for ( i= 0; i< 10000; i++)
{
WriteFiles("directory path..", "w+");
}
}
But it is not working and crashing particularly inside recursive function.
Can anyone help me out?
Thanks in advance

You will need to provide much more detail if you want help with this. We have no idea what "not working" means, or where it is crashing. Also, you need to understand that trying to write that many files at the same time will run extremely slowly as the system tries to schedule the different threads.

Apart from the problem, you also did not show the WriteFiles function that you have. The function that you have is not recursive, it does not call itself, or does it? If that does, remove the recursion as soon as possible.
Secondly, also show the code of that function.
OpenMP is helpful in most cases, but multithreading can be overkill in majority of the cases. Use with caution.

Until your code works with 1 file, non-recursively, don't bother adding the complexity of multiple files, in parallel, using recursion.
Start small until you have a firm understanding, and then bother building it up.

Unfortunately you did not give any error message or debug information.
Also wanted to point out that you will need to avoid the C runtime if you plan on opening more than 512/2048 files at a time. If you use the C wrappers you will be limited to 512 file handles which can be extended to 2048 via the _setmaxstdio function[^].

Hello all... I have this C code which I can compile and modify using NetBeans. But problems come when I try to separate some of the code to new files (.h & .c). I get these Unresolved External Symbols xxxxx. Example
int add(int a, int b);
int add(int a, int b)
{ return a + b; }
#include "newFile.h"
int main()
{
int result = add(5,6);
_getch();
return 0;
}
How do I overcome this error....thanks for anything you share.

You have to make sure that newfile.obj (or whatever it compiles to) is being linked during the build process.

Get yourself a copy of Visual Studio, it is much better for building C/C++/C# projects.

Hi all of you. How can I convert COleVariant to COLORREF ?
I have used CMFCPropertyGridColorProperty to store a colorref into CMFCProperrtyGrid, but I need to retrieve correctly the colorref value, because CMFCPropertyGridColorProperty have been filled with COleVariant ...
I get the value just like this:
CMFCPropertyGridProperty* pProp = m_wndPropList.FindItemByData(TRM_PROPERTYGRID_COLORWINDOW);
pProp->GetValue();
but GetValue get me COleVariant, and I have there COLORREF value ... how can overcome this ? I get the following error:
error C2440: 'return' : cannot convert from 'const COleVariant' to 'COLORREF'
Thank you.

Since COLORREF is a DWORD, can't you just access the ullVal member of COleVariant?

Hello all... how do I create array of char*. At the moment I have hardcoded the number of instances (large enough to hold tokens) but this should be generic. Example
int temp_array[2] = {0};
char* token1;
char* token2; As you can see, I might not know how many tokens I need at run time. I want something like this
char* [] tokens; How could I fix this? Thanks

Create a variable for the array that is initially empty and a variable holding the size:
char **tokens = NULL;
unsigned tokenSize = 0;
Once you know the required number of items, allocate the array. How to do that depends if you are using C or C++:
tokenSize = items_to_store_in_array;
tokens = new char *[tokenSize];
tokens = (char **)malloc(sizeof(char*) * tokenSize);
If you need to change the size use realloc with C.
With C++ you should then avoid arrays and use a container like vector - C++ Reference[^] instead.
