I have a little menu here which i want to execute my functions using it.
So i have problems in entering the process like notepad which i want to create, but then it crushes.
How can i declare the variable which will take care of the input process, because i didn't want to include it in the commandline when running. Part of my code is below

<br />
#include <windows.h><br />
#include <stdio.h><br />
#include <windef.h><br />
#include <winbase.h><br />
#include <imagehlp.h>   <br />
LPVOID lpMsgBuf;<br />
<br />
int menu(void)<br />
{<br />
int choice;<br />
<br />
	 printf ("\n");<br />
	 printf ("*****************************************\n");<br />
	 printf ("*\t\t\t\t\t*\n*\tCHECKPOINTING SYSTEM \t\t*\n");<br />
	 printf ("=========================================");<br />
	 printf ("\n=\t 1: Create a process    \t=");<br />
	 printf ("\n=\t 2: Shutdown the process\t=");<br />
	 printf ("\n=========================================\n");<br />
	 printf ("\n");<br />
<br />
	 printf("\nEnter choice (1-2): ");<br />
	 scanf("%d", &choice);<br />
	 return choice;	<br />
}<br />
int main(int argc, char **argv) <br />
{<br />
	PROCESS_INFORMATION pi ;       /* filled in by CreateProcess */<br />
	STARTUPINFO si;               /* startup info for the new process*/<br />
	LPDWORD lpExitCode = 0;<br />
	HANDLE hProcess ; <br />
	DWORD baseaddr = 0;<br />
	DWORD error = GetLastError();<br />
	LPCTSTR lpApplicationName="";<br />
<br />
int choice;<br />
menu();<br />
<br />
while((choice = menu())!=3)<br />
{<br />
switch (choice)<br />
{<br />
case 1:					<br />
printf("Enter process you want to execute: ",lpApplicationName);<br />
scanf ("%s",lpApplicationName);<br />
printf("Process %d reporting for creation\n",GetCurrentProcessId());//print out our process ID<br />
GetStartupInfo(&si);<br />
CreateProcess(NULL,		/* lpApplicationName */<br />
argv[1],          /* lpCommandLine  assumes to use curent process directory*/<br />
NULL,					/* lpsaProcess */<br />
NULL,					/* lpsaThread */<br />
FALSE,					/* bInheritHandles */<br />
CREATE_NEW_CONSOLE,     /* dwCreationFlags */<br />
NULL,					/* lpEnvironment */<br />
NULL,					/* lpCurDir */<br />
&si,					/* lpStartupInfo */<br />
&pi						/* lpProcInfo */<br />
);  <br />
  hProcess = pi.hProcess;<br />
  printf("New Process ID: %d ",pi.dwProcessId);<br />
  printf("has started \n"); <br />
break;<br />
case 2:<br />
<br />
TerminateProcess(pi.hProcess, GetExitCodeProcess(hProcess,lpExitCode ));<br />
GetLastError();<br />
<br />
break;<br />
default: printf("\nInvalid choice: ");<br />
}//while<br />
}<br />
return(0);<br />
}<br />

Try this:

#include "stdafx.h"<br />
#include <stdio.h><br />
<br />
int menu(void)<br />
{<br />
  int choice;<br />
  <br />
  printf ("\n");<br />
  printf ("*****************************************\n");<br />
  printf ("*\t\t\t\t\t*\n*\tCHECKPOINTING SYSTEM \t\t*\n");<br />
  printf ("=========================================");<br />
  printf ("\n=\t 1: Create a process \t=");<br />
  printf ("\n=\t 2: Shutdown the process\t=");<br />
  printf ("\n=========================================\n");<br />
  printf ("\n");<br />
  <br />
  printf("\nEnter choice (1-2): ");<br />
  scanf("%d", &choice);<br />
  return choice; <br />
}<br />
<br />
void main(int argc, char **argv) <br />
{<br />
  PROCESS_INFORMATION pi ; /* filled in by CreateProcess */<br />
  STARTUPINFO si; /* startup info for the new process*/<br />
  HANDLE hProcess;<br />
  TCHAR lpApplicationName[100]="";<br />
  <br />
  int choice;<br />
  <br />
  while((choice = menu())!=3)<br />
  {<br />
    switch (choice)<br />
    {<br />
    case 1: <br />
      printf("Enter process you want to execute: ",lpApplicationName);<br />
      scanf ("%s",lpApplicationName);<br />
      printf("Process %d reporting for creation\n",GetCurrentProcessId());//print out our process ID<br />
      GetStartupInfo(&si);<br />
      CreateProcess(NULL, /* lpApplicationName */<br />
        lpApplicationName, /* lpCommandLine assumes to use curent process directory*/<br />
        NULL, /* lpsaProcess */<br />
        NULL, /* lpsaThread */<br />
        FALSE, /* bInheritHandles */<br />
        CREATE_NEW_CONSOLE, /* dwCreationFlags */<br />
        NULL, /* lpEnvironment */<br />
        NULL, /* lpCurDir */<br />
        &si, /* lpStartupInfo */<br />
        &pi /* lpProcInfo */<br />
        ); <br />
      hProcess = pi.hProcess;<br />
      printf("New Process ID: %d ",pi.dwProcessId);<br />
      printf("has started \n"); <br />
      break;<br />
<br />
    case 2:<br />
      <br />
      TerminateProcess(pi.hProcess, 0);<br />
      break;<br />
<br />
    default:<br />
      printf("\nInvalid choice: ");<br />
    }<br />
  }<br />
}

And don't be as lazy as to believe anything you see...

Im sorry im using C language and now i'm having a problem with the header file
stdafx.h because i think it works in C++.
the error i'm getting shows this after adding the header file to the project.

<br />
Compiling...<br />
pro.c<br />
c:\program files\microsoft visual studio\vc98\mfc\include\afx.h(15) : fatal error C1189: #error :  MFC requires C++ compilation (use a .cpp suffix)<br />

<br />
pro.obj - 1 error(s), 0 warning(s)<br />

Comment the #include "stdafx.h" line.

well now it works even after re-including the header file.
But now it does not create the notepad process and im amazed that its ID is -858993460 though it doesn't appear

It does. Check out the source again and look for GetStartupInfo(&si). ~~Reinsert it into your code.~~

No, wait! Just replace it with:

<br />
<br />
      ZeroMemory( &si, sizeof(si) );<br />
      si.cb = sizeof(si);<br />
      ZeroMemory( &pi, sizeof(pi) );<br />

I replaced the code lines you suggested but still it doesn't showup the process running, i.e. notepad or cmd. I tried to tackle it anyhow but still... and what i am concern with is that the process ID it shows is the same everytime i try to create it

Ok if you assigned the File Buffer to CString Variable.
Then you can use CString::Replace(..) to replace all text with ""

Some thing like this

[Code] 
 CString szTmpString="CodeProject was Great Site";
 szTmpString".Replace("was","is");

 In your case replace [text to remove] with ""
