چطور میشه یک handl یک برنامه رو بدست آورد ؟
البته نمی خوام handl رو به کمک title برنامه بدست بیارم چون ممکنه یک برنامه پنجرش بصورت مخفی (hiden) باشه .
من دنبال روشی هستم که نام برنامه رو بدم مثلا notepad.exe و در صورتی که وجود داشته باشه handl اون رو برگردونه
البته بکمک CreateProcess تونستم که handl برنامه ای رو که داخل برنامه اجرا کردم رو بدست بیارم اما نمیدونم چطور handl مربوط به برنامه های دیگر را بدست بیارم
