请高手多帮帮忙!

简单办法：FindWindow（）；

复杂点儿的：查找系统中相应的进程

//enum process to find a certain module
void CPtbView::IsAppRun(CString modulename)
{
DWORD buf[4096];
DWORD num;
TCHAR filenamebuf[_MAX_PATH+1];
HMODULE hModule;
DWORD cbReturned;
BOOL bret=EnumProcesses(buf,4095,&num);
bool bfound=false;
CString msg;

if(!bret)
{
AfxMessageBox("Error EnumProcesses");
return;
}

for(int i=0;i<(int)num;i++)
{
HANDLE hProcess =OpenProcess(PROCESS_QUERY_INFORMATION¦ PROCESS_VM_READ,false,buf[i]);
if(hProcess ==NULL)
continue;
bret=EnumProcessModules(hProcess ,&hModule, sizeof(hModule), &cbReturned );
if(bret)
{
DWORD dwret=GetModuleFileNameEx(hProcess ,hModule,filenamebuf,_MAX_PATH);
CloseHandle( hProcess ) ;
if(dwret==0)
{
msg.Format("%d",GetLastError());
AfxMessageBox(msg);
break;
}
else
{
TCHAR* pfind=_tcsstr(filenamebuf,modulename);
if(pfind)
{
bfound=true;
break;
}
}
}
}
if(bfound)
AfxMessageBox("Found it");
else
AfxMessageBox("Not found");
}

void CPtbView::OnViewCheckrun()
{
IsAppRun("notepad.exe");
}
