Hi

How to differentiate MFC functions and SDK and what are the differences between these two. Please help me in this regard.

Thanks

Microsoft Platform SDK is freely available from Microsoft. It contains all header files, libraries and tools required to develop Windows applications. It contains some samples and documentation also. But it does not have any good object oriented window library like MFC. It is really difficult and challenging to produce high functionality applications with a great looking GUI and all.

But on the other hand, MFC is set of classes (Not free), that has wrappers for windows API, written in C++. There might be other packages those are similar (Think class library by symantec, and Object windows library by Borland, etc...) but MFC is the most celebrated package when it comes to windows application development with GUI.

You can freely download the Platform SDK from Microsoft, whereas you cannot do so with MFC. Is that what you are referring to?

Little OT question Sir, Is there is Some diffrence between Windows SDK and Plateform SDK?

The Windows SDK is a subset of the Platform SDK.

if the "winmain()" is visible, its an SDK program, if not it could be MFC.
SDK is programmed using C for calling APIs directly (though u can create your own classes in C++)
MFC is object oriented fully C++ based, wraps the raw API and gives you a faster way to create applications.

first learn SDK, then come to MFC. never land on MFC straight away. the mistake which i did Frown | :(

Then you'd be asking "what the heck is windproc and whatz a winmain??!"

if the project is done in MFC , it'll have MFC functions . if it is done in SDK , it will have SDK functions. Roll eyes | :rolleyes:

Buddy, MFC is just a Object oriented Wrapper Over Windows SDK api.. which simplify working with apis easily.. thats a only major diffrence between them

How to implement it in XP?

I would like to know how to implement it in XP?

MOV AX, 6F09H ; Setting the Digital port is output
MOV BL, 09H ; Digital value is 09H
INT 15H

Can it be implement with inpout32.dll?
Please help!

normanS30-Nov-05 18:50

30-Nov-05 18:50

The C compiler can handle inline assembly code, although I have never used this myself - maybe you could just use that?

Alternatively, a quick google tells me that INT 15H gives access to various BIOS calls, mostly related to memory maps etc., but after a 5-minute search I did not see INT 15 with those AX and BL values. So take a step back, and tell us what you are actually trying to do. What information are you looking for / what do you expect this call to do?

LaHaHa30-Nov-05 20:59

Thank you for answering my message!

In fact that it is the control of Digital I/O of an industical PC.
I need to use mfc to do it because it is only a part of my program.
Can you give me more hints to do it?
Please help!

My guess would be that there are 2 options - see if you can use the exact assembler code you list (MOV, MOV, INT), or else find out what the calls actually do, and try to repeat that functionality using C++.

This article http://www.codeproject.com/cpp/extasm.asp[^] has examples on how to include assembly statements into your code. There are restrictions on what you have privilege to do as a "normal" program (i.e. not part of the kernel) but I can not remember that stuff any more. If you want some ideas, look at http://www.codeproject.com/system/soviet_kernel_hack.asp[^] - I have no idea what that article means, though!!!

Trying to find out what the code actually does may be easier, as long as the system is not too old. What documentation do you have? The programmer's guide for the PC, which should be available if you are trying to use features which are specific to the PC, should have this information.

Thank you very much!
I found that it is using a chip set W83627HF.
Now I can use the "inpout32.dll" to set it.
Do you how to access it without using "inpout32.dll"?
I think it should have driver inside the Windows.
Please help!

normanS2-Dec-05 1:41

To start off, download www.winbond.com/PDF/sheet/w83627hf.pdf[^], if you do not have it already.

This PDF document tells you for the Winbond chip what information is available at what port address, so you can use InpOut32.DLL to read information, or to write settings. For example, look at figure 2.1 on page 23.

But this still does not tell you how to replace the MOV, MOV, INT instructions. As far as I know, the MOV, MOV, INT instructions are motherboard BIOS functions - if you can find out what these actually do (maybe from motherboard documentation), maybe you can use the W83627 documentation and get the same effect by using INPOUT32 to write to or read from ports.

LaHaHa2-Dec-05 4:27

2-Dec-05 4:27

Now I can use the inpout32.dll to do the same effect.
But I would like to do it without using inpout32.dll.
Do you have any suggestion?
Please help!

normanS4-Dec-05 18:17

Sorry - I used inpout32.dll when I wanted to do direct port I/O! I was quite happy with it.

Since you have not said what the BIOS call actually does, I can not guess how to implement it.

My suggestion would thus be to try to use inline assembler, and use the exact assembly instructions you gave in the original post.

You may have problems with privilege, in which case, search codeproject for PRIVILEGE, and see if you find anything useful.

LaHaHa4-Dec-05 19:58

4-Dec-05 19:58

The BIOS call is used to control the General I/O port of W83627HF chip set.
I just want to make my own driver instead of using inpout32.dll.

normanS4-Dec-05 23:52

4-Dec-05 23:52

OK, seems a reasonable goal.

When I had to do port I/O under Windows NT / XP, I chose the easy route and used inpout32.dll. Others choose to do it the difficult way, but they learn more in the process!

Good luck.
