Всем привет!
Пусть моя прога создает файл с расширением ord. Я хочу чтобы по двойному нажатию на файлы с таким расширением запускалась моя прога. И еще когда программа будет запускаться, как она поймет что нужно открыть файл по котороу нажимали? Мне говорили что нужно зарегистрировать расширение в системе, что то вроде этого, вообщем как все это сделать? спс.

В общем, так!!
Не буду тратить время на объяснение, а сразу скажу, что и как делать.
Для начала, создай модуль и помести следующий код(в нем есть что то лишнее, но я думаю что именно ты разберешься сам):
===============================================================
Public Const REG_SZ As Long = 1
Public Const REG_DWORD As Long = 4
Public Const HKEY_LOCAL_MACHINE = &H80000002
Public Const HKEY_CLASSES_ROOT = &H80000000
Public Const HKEY_CURRENT_USER = &H80000001
Public Const HKEY_USERS = &H80000003
Public Const ERROR_NONE = 0
Public Const ERROR_BADDB = 1
Public Const ERROR_BADKEY = 2
Public Const ERROR_CANTOPEN = 3
Public Const ERROR_CANTREAD = 4
Public Const ERROR_CANTWRITE = 5
Public Const ERROR_OUTOFMEMORY = 6
Public Const ERROR_INVALID_PARAMETER = 7
Public Const ERROR_ACCESS_DENIED = 8
Public Const ERROR_INVALID_PARAMETERS = 87
Public Const ERROR_NO_MORE_ITEMS = 259
Public Const KEY_ALL_ACCESS = &H3F
Public Const REG_OPTION_NON_VOLATILE = 0

'Удаление ключа

Dim lRetVal As Long
lRetVal = RegDeleteKey(lPredefinedKey, sKeyName)
End Function
Теперь для того чтобы привязать файлы «.ord» к твоей проги, вот код, можеш поместить его в загрузку формы:
CreateNewKey HKEY_CLASSES_ROOT, ".ord\shell\open\command" ‘создаем нужные разделы в реестре
SetKeyValue HKEY_CLASSES_ROOT, ".ord\shell\open\command", "", "C:\Проект12.exe", REG_SZ ‘"C:\Проект12.exe" - прописываем путь к нашей программы
Вот и всё!!!

Для файлов с расширением .hello
My.Computer.Registry.ClassesRoot.CreateSubKey(".Hello" .SetValue("", "Hello", Microsoft.Win32.RegistryValueKind. String)
My.Computer.Registry.ClassesRoot.CreateSubKey("Hello\shell\open\command" .SetValue("", Application.ExecutablePath & _
" ""%l"" ", Microsoft.Win32.RegistryValueKind. String)
