You can't run Windows applications on DOS. You can make a console application that runs on Windows that uses MFC but that's a different situation; but some people use the word DOS to mean a console application which is why I mention it.

As i get from you reply.
Windows applicxation cannot run on DOS operating system, but a consol based application can run on windows infact this consol based application is not basicaly a DOS application.
So to run a consol based application windows Operating system must be installed.
As i think DOS is a 16 bit operating system and windows is 32 bit operating System that why the windows applications cannot run on DOS operating system is it .
thanks
Regards.

Microsoft droped support for writing applications in DOS over 10 years ago. I believe VC4 did not even support DOS.

You can use Visual C++ 1.5 (1993 if I remember well), it has an option for DOS console application.
Also I think it was the first time when MFC was introduced, but I don't think you can use MFC for a console application.
There were dlls available for a DOS application, by the way? I think they are available for 16-bit and DOS only under Windows (3.11 etc.), I think the type of application was called QuickDOS or so (a pseudo-console emulated under 16-bit Windows).
Consider a rewrite in C - it's not really necessary to use MFC for a console application anyway just for CString or whatever are the few classes you need. Even talking about Win64 - what kind of console application needs a heavy GUI library as MFC to worth its usage?

I need to send text as stream/Bytes to MFC Active-X control and read the content in MFC and display the same in Text box. Since i am very new to this world i couldn't grasp things immediately so If possible please provide me code snippet both ActiveX control and Wrapper program.

Thanks in Advance.

how come we give you source code for reading file, when that wrapper class havn't exposed to us!

Hi All,
I am working on addin development for visual studio 6. I am going to add a menu under Tools to get .dsw file path through a dialogbox. After pressin ok button of this dialogbox, i want to open (and close already opened workspace) given .dsw file in visual studio IDE.
Visual Studio 2005 has Solution.Open(string solnPath) method provided by DTE2 itnerface. I am looking similar thing for visual studio 6.
Thanks in advance.

ShellExecute is what you want.

Hi Jonh,
thanx for suggestion, but there are some more complications. 
1. I want to open .dsw file in same IDE. I have tried to use ShellExecute() function in my Visual Studio 6 IDE. But as I have visual studio 2005 also installed on my machine and .dsw file, by default, opens with VS2005, VS2005 instance is get created and opend .dsw file. Which i don't want to achieve.
2. Secondly, the file which we are going to open, (say, .dat or .txt) should have association with an executation file (open with setting). Someone may consider .dat as movie file and opens with media player, and one will consider it as simple text file and opens with notepad.
In this scinario respective application will execute and open the file.
I have tried same thing (creation of addin for vs2005 to open .sln file) with VS2005, one can call DTE2 interface's Solution.Open(string filename) method.
As DTE is interface for current running IDE instance, solution get opened in same IDE. I want same thing for studio 6.
Can I invoke "open workspace" command through code? (what mainly done by using File->open workspace option of same IDE).

wow what about
ShellExecute(NULL,"msdev.exe","project.dsw",NULL,SW_SHOWNORMAL);

Thanx Alok,
It works, but again a new instance of VS6 is created and i want to open in same instance of IDE. I want to perform similar operation like "File->open workspace" of IDE (without showing select file dialog) more correct example is open "File->recent workspaces" option. How IDE takes filename from registry and opens it in IDE?

Hi,
I have developed the program that let user record video as avi file and audio wav file separate, and now I want to develop the orther program to let user merge these to one avi file.
I have not used DirectShow in my code for this module.
Please help me for this.

Instead of saving separate AVI and WAV files and then using additional code to combine the AVI and WAV files, I think it would be cleaner / better to update the code which writes the AVI file so it saves an AVI with audio and video.
I did something similar - I wrote a program which saved video-only AVIs (based on the MSDN WriteAVI sample), then later updated it to save audio in the AVI file. If you decide to follow that route, I will clean it up a bit (it's a long function) and post the code. My program is C, not C++, but it should be useable.

Hi,
The follow are some my codes. I finished to write a Avis and wav(write by other thread) then continue to add the wav to Avis file existing.
Please help me for some suggestions and code example.
With the follow code it can write but I can't play final avi file with Window Media, Real Player, it seem to wrong codecs or format
I have used the compression codecs option as MSVC(Mircorsoft Video Codecs 1)
Please help me again.

Please modify your post - I can't read the code easily. Select the code and click on the Formatting: pre label below the text entry box - this tells CodeProject to keep formatting as you had it in the code.
It is always useful to do Preview before you Post message.
I will find my code and try to make a short extract, then post that. The details look similar so it may be useful.

Sorry for make difficulty to read,
Please help me with some your code
