After the CAB File Extraction
Cab f iles that need to cause a warm reset after cab extraction will need to
create the __RESETMEPLEASE__.TXT file in the “\Windows” directory.
The preferred method to create this file is within the DllMain portion of
the SETUP.DLL file. It looks like this:
#include <windows.h>
#include <Tlhelp32.h>
#include <winioctl.h>
#include <ce_setup.h> // in the public SDK dir
#define IOCTL_TERMINAL_RESET CTL_CODE (FILE_DEVICE_UNKNOWN,FILE_ANY_ACCESS,
2050, METHOD_NEITHER)
BOOL APIENTRY DllMain( HANDLE h, DWORD reason, LPVOID lpReserved )
{
return TRUE;
} // DllMain
//************************************************************************
// $DOCBEGIN$
// BOOL IsProcessRunning( TCHAR * pname );
//
// Description: Get process table snapshot, look for pname running.
//
// Arguments: pname - pointer to name of program to look for.
// for example, app.exe.
//
// Returns: TRUE - process is running.
// FALSE - process is not running.

if ( hProcList == INVALID_HANDLE_VALUE ) {

} // end if
memset( &peProcess, 0, sizeof(peProcess) );

if ( !Process32First( hProcList, &peProcess)){
