注：pe.szExeFile有时候是全路经文件名，有时候只是文件名，原因有待考究，或者请哪位高手指教
DWORD GetProcessIdFromName(LPCTSTR name)
{
PROCESSENTRY32 pe;
DWORD id = 0;
HANDLE hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
pe.dwSize = sizeof(PROCESSENTRY32);
if( !Process32First(hSnapshot,&pe) )
return 0;
do
{
pe.dwSize = sizeof(PROCESSENTRY32);
if( Process32Next(hSnapshot,&pe)==FALSE )
break;
if(strcmp(pe.szExeFile,name) == 0)
{
id = pe.th32ProcessID;
break;
}
} while(1);
CloseHandle(hSnapshot);
return id;
}
