Can you be more specific. Why would you want to open a program then open another program and tell that program to open your program again? Maybe I missunderstood someting. Please, rephrase the question.

Do you mean.. How do I Associate an Extension with my Application?..
Like when you double Click a File ending with .txt it launches it in Notepad?

If so, then here's an example which Asscociates the file Extension .abc with Notepad..

Private Declare Function RegCreateKeyEx Lib "advapi32.dll" Alias "RegCreateKeyExA" (ByVal hKey As Long, ByVal lpSubKey As String, ByVal Reserved As Long, ByVal lpClass As String, ByVal dwOptions As Long, ByVal samDesired As Long, lpSecurityAttributes As Any, phkResult As Long, lpdwDisposition As Long) As Long
Private Declare Function RegSetValueEx Lib "advapi32.dll" Alias "RegSetValueExA" (ByVal hKey As Long, ByVal lpValueName As String, ByVal Reserved As Long, ByVal dwType As Long, lpData As Any, ByVal cbData As Long) As Long
Private Declare Function RegCloseKey Lib "advapi32.dll" (ByVal hKey As Long) As Long

Private Const HKEY_CLASSES_ROOT = &H80000000
Private Const REG_CREATED_NEW_KEY = &H1
Private Const REG_OPENED_EXISTING_KEY = &H2
Private Const REG_SZ = 1

Private Const STANDARD_RIGHTS_ALL = &H1F0000
Private Const KEY_QUERY_VALUE = &H1
Private Const KEY_SET_VALUE = &H2
Private Const KEY_CREATE_SUB_KEY = &H4
Private Const KEY_ENUMERATE_SUB_KEYS = &H8
Private Const KEY_NOTIFY = &H10
Private Const KEY_CREATE_LINK = &H20
Private Const SYNCHRONIZE = &H100000

Private Const KEY_ALL_ACCESS = ((STANDARD_RIGHTS_ALL Or KEY_QUERY_VALUE Or KEY_SET_VALUE Or KEY_CREATE_SUB_KEY Or KEY_ENUMERATE_SUB_KEYS Or KEY_NOTIFY Or KEY_CREATE_LINK) And (Not SYNCHRONIZE))

Private Sub Command1_Click()
    Dim lRegKey As Long
    Dim lResult As Long
    Const sApp = "Notepad.exe %1" 'App to Run
    Const sExt = ".abc"           'Extension to Associate
    Const sExtDesc = "ABC File"   'Descriptive Name of Extension
    
    Call RegCreateKeyEx(HKEY_CLASSES_ROOT, sExt & "\", 0&, "", 0&, KEY_ALL_ACCESS, ByVal 0&, lRegKey, lResult)
    If lResult = REG_CREATED_NEW_KEY Or lResult = REG_OPENED_EXISTING_KEY Then
        'Reg Opened/Created Successfully..
        lResult = RegSetValueEx(lRegKey, "", 0&, REG_SZ, ByVal sExtDesc, Len(sExtDesc))
        Call RegCloseKey(lRegKey)
        If lResult = 0 Then
            'Value set successfully..
            Call RegCreateKeyEx(HKEY_CLASSES_ROOT, sExtDesc & "\Shell\Open\Command\", 0&, "", 0&, KEY_ALL_ACCESS, ByVal 0&, lRegKey, lResult)
            If lResult = REG_CREATED_NEW_KEY Or lResult = REG_OPENED_EXISTING_KEY Then
                'Reg Opened/Created Successfully..
                lResult = RegSetValueEx(lRegKey, "", 0&, REG_SZ, ByVal sApp, Len(sApp))
                If lResult = 0 Then
                    MsgBox "Extension Associated"
                Else
                    MsgBox "Failed to Associate Extension"
                End If
            End If
        End If
    End If
    Call RegCloseKey(lRegKey)
    
End Sub
