يك كليد تويه رجيستري ساختم و مي خوام برنامه‌ام وجود اونرو چك كنه

با سلام به همه دوستان من يك كليد تويه رجيستري ساختم و مي خوام برنامه‌ام وجود اونرو چك كنه اگر مي شه كدي كه اين كارو مي كنه به من بديد

اول با اين تابع كليد بالايي رو باز كن.

کد:

---

Public Declare Function RegOpenKeyExA Lib "advapi32" (ByVal hKey As Long, ByVal lpSubKey As String, ByVal ulOptions As Long, ByVal samDesired As Long, ByRef phkResult As Long) As Long

---

بعد با اين api كليدتو سرچ كن.

کد:

---

Public Declare Function RegEnumKeyExA Lib "advapi32" (ByVal hKey As Long, ByVal dwIndex As Long, ByVal lpName As String, lpcbName As Long, ByVal lpReserved As Long, ByVal lpClass As String, lpcbClass As Long, lpftLastWriteTime As Any) As Long

ُسلام دوست عزيز اين فانكشن رو اگه كامل توضيح بدي خيلي ممنون مي شم در ضمن اگه مي شه تين رو به صورت شرطي كه اگر بود يك عمل انجام بده و اگر نبود يك كار ديگه بكنه بنويسي

از msdn كمك بگير ديگه من هم با msdn ياد گرفتم. توضيحش وقت گيره.

متاسفانه من الان msdn ندارم اگر فقط كد شرطيرو بنويسي ممنون مي شم

اين يه مثال
RegOpenKeyExA HKEY_CLASSES_ROOT, "Software\Microsoft\MediaPlayer", 0, KEY_READ, hKey
hKey هندل اين كليد هست: HKEY_CLASSES_ROOT\Software\Microsoft\MediaPlayer
حالا ميتوني اين كليد رو پاك كني يا تو اين كليد دنبال كليد ديگر يا يك value بگردي يا ...
با تابع RegEnumKeyExA ميتوني دنبال كليدت بگردي. به اين صورت:

ممنون عزيزم

قابلي نداشت.
