It looks as though you already have. What's the problem?

Well i dont know to add another sorting like selection sort..whereby it would perform the same actions as the coding.I don't know to make a menu driven of choosing the sorting also.

what is the question again ?

Why did you paste your ENTIRE program again? Once is MORE THAN enough.

I am sorry..well i didnt mean that..well the coding which i've pasted earlier... i would need to implement another sorting method as well.Im choosing selection sort.But i don't know to include it into the coding ...so i would need to be having a menu such as choose either insertion or selection ...and then it would go into the float a..please do guide me.Well it should also do the sorting,comparison and also the time.Thank you.

For pete's sake, man, ditch this program and start with something way more simple. I suggest purchasing a book or at least borrowing one from your local library.

No offense personally, but to carry on with your current endeavor is a waste of your time and ours. Learning how to code up a useful program, while fun, is completely comprehensive in that one step builds upon the previous one. Skipping the small stuff is just a recipe for failure.

Let me get this straight. YOu've written a sorting algorithm, something pretty complex, by you can't write something that puts up a menu and accepts a little keyboard input, something VERY simple???

Tell me why I seriously doubt you wrote the sorting algorithm... Sounds more like copy'n'pasted one to me.

Is anybody familiar with SQLPassThrough? Is this just an old VB way of doing things, or does it also exist through VC++? If it isn't in VC++ what would the equivalent be?

I'm not sure if this is what you're referring to, but it seems this is related to direct
queries to a database, bypassing ODBC.

If so...

In the MFC ODBC classes, there's CDatabase::ExecuteSQL() and CRecordset::Open() with the executeDirect option.

For ODBC using the ODBC APIs, there's SQLExecDirect().

I'm writing a logging program for virtual COM port connected sensors which is later on going to communicate with a framegrabber for syncronisations purposes. For simplicity I wanted to run the program in a command window but MFC and iostream seems to have a hard time cooperating. I need access virtual serial ports and later on threading for the framegrabber (video input).

First: Is it a dead end to use iostream and a command window for my needs? Do the MFC components refuse running in a command window?

Second: If iostream and MFC should work together (I don't have any previous experience with MFC so I barely know what I'm speaking about) how do I get around my linking problems? I get the evil LNK2005 error, eg.:

nafxcw.lib(afxmem.obj) : error LNK2005: "void * __cdecl operator new(unsigned int)" (??2@YAPAXI@Z) already defined in libcpmt.lib(newop.obj)

when I'm linking. It seems to be the "new" and "delete" operators which are the problem. I've already looked through the MS article on the topic (ID : 148652) but I still can't figure out how to get around it.

#include <afx.h>
#include <iostream>

,plus an almost empty main, gives me the error. What have I gotten wrong?
I'm using MS Visual Studio .NET 2003.

They do. In dayly work with VS.NET 2003 and 2005.

I include the STL-stuff in stdafx.h, before including the MFC-stuff and there is no linker problem.

Please do a minimal test-program showing your problems and post it.

Are you perchance using new for a global static variable?

Though I speak with the tongues of men and of angels, and have not money, I am become as a sounding brass, or a tinkling cymbal.
George Orwell, "Keep the Aspidistra Flying", Opening words

I'm at home now but I think it all boiled down to:

#include <afx.h>
#include <iostream>

void main()
{
std::cout << "test";
};

Now when I think about it I guess afx.h is a litte overkill. I got stuck on the solution proposed in the MS article. I used more specific include files like winbase.h to start with. I'm not sure if it caused the same problem.

Why don't you create a new console project and select MFC support, will that not fix the problem? Then you can diff to see what you're missing???

I got my to work just fine.

Thanks alot!
I did get it to work but I still cannot figure out what the difference is. That was about what I started with. I guess I have to scrutinize every single character to see if I can produce the same error.

why don't you use a diff tool like windiff to find out what it different from you project (.vcprof) file and the one produced by with Wizard..will be a lot faster!!!
