1. CreateProcess[^] or ShellExecute[^]
2. Google is your friend, but look at this[^].

createprocess() can start a process but cannot restart a running process.

Sorry, i thought by "restart" you meant that the process got killed/exited by someone else, for example by a user action and you wanted to restart it again.

I just replied to your yesterday's post. Ignore it. Answer me here: What *exactly* are you trying to achieve. Why restart a Win32 Process? Why use both Win32 and MFC? None of this makes sense to me.
We may probably be able to suggest you a much better way of doing it, but only if you explain what are you trying to do.

sorry but i could not find my old question.
i created the win32 c++ application long back when i dont have any idea of mfc. it is working fine.
with mfc, i create a gui which accept the some content and save them in text files. these text files are then used by the win32 application. win32 application runs at startup of windows and it takes the information from the files and starts using it (it is socket application so it will not read the file again until it receives some information for the ip which is saved in the text file).
so i want to restart the win32 application when closing mfc application so that win32 application can use the updated text files.
actually i want to use TerminateProcess() and then start it with CreateProcess() function. but i read that TerminateProcess() can create problem with DLL structure.

How hard is it to add MFC support to the console application and send a message to it so that it reads the new file again in response to the message? I understand you are having a trouble communicating from your MFC app to the console app?

the win32 application is not a console application. i dont know how to communication between the two application can be set.
in vs2008, i used win32 project (not win32 console application) for creating the win32 application. also the header files used are ---
#include <windows.h>
#include <winsock.h>
#include <tchar.h>
#include <wchar.h>
#include <iostream>
#include <fstream>
#include <shlwapi.h>

Does you application contain or create a window. If yes, you can use Window Messaging to communicate between two application, just add common message id between two application, and related function in WndProc function for win32 application and between BEGIN_MESSAGE_MAP and END_MESSAGE_MAP for MFC application.

there is no create window function in the win32 application. there is only messagebox().

You could send the win32 app a message and a message handler to it. There are several tutorials on IPC in CP, just take a look at those.

Can Someone help I am not sure whats wrong.
I am getting the following debug message:
First-chance exception at 0x5d0c373e in Capture Data.exe: 0xC0000005: Access violation writing location 0x0043454c.
However on exit I get:
The program '[1284] Capture Data.exe: Native' has exited with code 0 (0x0).
Here is the code I have used:
BOOL CCaptureDataApp::InitInstance()
{
InitCommonControls();
CWinApp::InitInstance();
CCaptureDataSheet sheet("My Very Own Property Sheet App",NULL,0);
sheet.m_psh.dwFlags |= PSH_NOAPPLYNOW;
m_pMainWnd=&sheet;
INT_PTR nResponse=sheet.DoModal();
return FALSE;
In the Capture Data Sheet
IMPLEMENT_DYNAMIC(CCaptureDataSheet, CPropertySheet)
CCaptureDataSheet::CCaptureDataSheet(UINT nIDCaption, CWnd* pParentWnd, UINT iSelectPage)
:CPropertySheet(nIDCaption, pParentWnd, iSelectPage)
{
AddPage(&m_Page01);
AddPage(&m_Page02);
}
CCaptureDataSheet::CCaptureDataSheet(LPCTSTR pszCaption, CWnd* pParentWnd, UINT iSelectPage)
:CPropertySheet(pszCaption, pParentWnd, iSelectPage)
{
AddPage(&m_Page01);
AddPage(&m_Page02);
}
CCaptureDataSheet::~CCaptureDataSheet()
{
}
BOOL CCaptureDataSheet::OnInitDialog()
{
BOOL bResult = CPropertySheet::OnInitDialog();
}

I don't know why you get that exception but try turning on "Break into debugger on exceptions" in Visual Studio, it might show you where exactly the exception gets thrown. (In VS2003 it's under Debug->Exceptions in the menu)

This is where i am stuck in the debgugger. Not sure whats happening?
BOOL AFXAPI AfxDeactivateActCtx(DWORD dwFlags, ULONG_PTR ulCookie)
{
BOOL rc = pfnDeactivateActCtx != 0 ? pfnDeactivateActCtx(dwFlags, ulCookie) : FALSE;
return rc;
}
Why would it exit with a 0 if I haven't changed anything else in the code?
Would it not give me a memory leak or something?

I am sorry I am not trying to be a pain. This is frustratung me...
Here is what I did...Any suggetions...
On a different machine i went down in versions..from 2008-2005-and finally to VStudio 6.
I used the same steps in all ..I got the same exception error except in Vstudio 6..Where I got no exception error...Imported the same project into my Visual Studio 2008 and it works fine...No First-chance error.
I am not sure what to do?...Well for now I can work with this imported project...but is this really a solution?...I have come to the end of the rope on this one...If I did something wrong, would VStudio 6 not complain as well?
Do you think you can advice me as what to do? I don't like to give up, at the sametime I don't want to be hitting my head if it is a bug in VStudio 2008?
I can't see me to be the only one trying or using the property sheet based application?
Thanks, I will really appreciate some sort of feed back, I am new at this and it's frustrating me..Please advice.

Is it possible that maybe all your project needed was a complete rebuild?
