The thing you are trying to do could be hard to implement, since the C51 program running in the Keil compiler is in Keil's own address space etc, and not running independently, because it is not an executable program; It only runs inside the Microcontroller.
My personal opinion:
If you need to create communication between two different programs, then write them both in VC++.
If you really need to communicate with a C51 program, then you would have to take a look at:
Inter-process communication. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/ipc/base/interprocess_communications.asp[^]
API Hooking. (Maybe too.) http://www.codeproject.com/system/hooksys.asp[^]
Also you could do some research on emulating the Keil compiler; (i.e, writing a program which in turn runs a Keil's C51 program).
this is this.

Hi folks,
I've got a need to re-route printing based on a given condition. Basically, when the user selects file | print in my MDI doc/view, I need to open a different doc (of the same type) and print that instead. So far, I've been opening the other document in view::DoPreparePrinting (after the call to the base class, so the user can select their desired printer), calling newView->OnBeginPrinting, newView->OnPrint & newView->OnEndPrinting manually and then closing the document. This prints the original view though.
Anyone had to do this before? Could you point me in the right direction? It would be great if I could get print preview to preview the other document too.

Hi,
Override OnPrint( CDC* pDC, CPrintInfo* pInfo) virtual function and draw whatever u want in that DC. The default implementation calls the OnDraw member function and passes it the printer device context. Thats why you r getting the original view.

After a proper nights sleep I've taken another look at the problem.... What I should have been doing is opening, printing / print previewing and closing the document in question in the OnFilePrint and OnFilePrintPreview handlers - not in DoPreparePrinting!
Do'h, so simple when you think about it properly...

what does the post build event do ? register any service or ... ?

Thank you for your reply! You're right, it looks like it just copies the execuatable to another folder. Duh! I must be getting tired. Thanks again.

Hi,
I think its not a serious problem. It might register some service which you can do in command prompt.

Something Wrong here! Is that an error? As Message Header shows you have deleted the message and inside text show that you are arguing with some for Message

No, I was just replying to the first post which has been deleted (that is why the header is: Re: [Message Deleted]).
I mean, why delete the posts when you get an answer ? That's a little bit selfish. Now other people are not able to follow the discussion because they just have an answer to a deleted question.

Hi,
I derived a class from CFileDialog and added a ComboBox manually, in absence of the normal VS dialog editor (as the CFileDialog isn't public). I also add message handling for the ComboBox manually, but I can't make it work.
here's some code.
BEGIN_MESSAGE_MAP(CImageFileDialog, CFileDialog)<br />
ON_CBN_SELCHANGE(IDC_BROWSEBYCOMBO, OnBrowseBySelChanged)<br />
END_MESSAGE_MAP()
The problem is that OnBrowseBySelChanged is never reached.
Is there any blocking of message handling of undocumented MFC classes, and in that case how do I get around it?
Thanx in advance!

Thanx, that was very useful. 
A studier of that sample have to change edt1 to cmb13, though. At least I had to, to make it runnable.

AFAIK, there is no such function... I believe you have to make your own.. you can use CFileFind Class to achieve same...

Something like:
bool IsFolderEmpty( LPCTSTR lpszFolder )
{
CFileFind fileFind;
CString strFolder(lpszFolder);
bool bFound,
bEmpty = true;
bFound = fileFind.FindFile(strFolder + _T("*.*"));
while (bFound != FALSE)
{
bFound = fileFind.FindNextFile();
if (! fileFind.IsDots())
{
bEmpty = false;
break;
}
}
return bEmpty;
}

hi
i am converting a MFC ,MDI application to unicode.
when i run the program in release version it runs fine but once i set the config to Unicode Release it just crashes at the start itself.(doesn't even show error msg but abruptly stops the execution of the program)
There are no compile time and linker errors.
i kept breakpoints and arrived at the conclusion that the crash occurs at following lines of code in InitInstance().
CMainFrame* pMainFrame = new CMainFrame;
if (!pMainFrame->LoadFrame(IDR_MAINFRAME))
return FALSE;
m_pMainWnd = pMainFrame;
is there too much of difference between release and unicode version??
how to go abt solving that error....
Thanx in advance

Hi,
Do you call any other functions from InitInstance(). If yes, check whether you are handling any unicode data.

Is the entry point set to 'wWinMainCRTStartup'? I ended up putting this in builds a long time ago for UNICODE:
#ifdef _UNICODE
#ifdef _AFXDLL
#ifndef _AFXEXT
#ifndef _WINDLL
#ifndef _USRDLL
#ifndef _CONSOLE
#pragma message("Project appears to be an MFC executable, changing entry-point function")
#pragma comment(linker,"/entry:wWinMainCRTStartup")
#endif
#endif
#endif
#endif
#endif
#endif
