Try this to Register a DLL programmingly:

in a module:

'Public Declare Function DllRegisterServer Lib "ComCtl32.OCX" () As Long

Public Declare Function FreeLibrary Lib "kernel32" (ByVal hLibModule As Long) As Long

Public Declare Function LoadLibrary Lib "kernel32" Alias "LoadLibraryA" (ByVal lpLibFileName As String) As Long

Public Declare Function GetProcAddress Lib "kernel32" (ByVal hModule As Long, ByVal lpProcName As String) As Long

Public Declare Function CallWindowProc Lib "user32" Alias "CallWindowProcA" (ByVal lpPrevWndFunc As Long, ByVal hWnd As Long, ByVal msg As Any, ByVal wParam As Any, ByVal lParam As Any) As Long

Public Const ERROR_SUCCESS = &H0

Public Sub RegisterDLL(ByRef frm As Form, ByVal DLLPath As String, Optional Register As Boolean = True)

On Error GoTo ErrHandler

If Trim$(DLLPath) = "" Then Exit Sub

If Register = True Then

Dim temp As String

temp = GetSystemDir

If LCase$(DLLPath) <> LCase$(temp & "\" & dir$(DLLPath)) Then FileCopy DLLPath, temp & "\" & dir$(DLLPath)

'RegisterServer frm.hwnd, DLLPath, True

RegisterServer frm.hWnd, temp & "\" & dir$(DLLPath), True

' If Dir$(GetSystemDir & "\regsrv32.exe") = "" Then

' Shell "regsvr32 " & Dir$(DLLPath)

' Else

' Shell App.Path & "\" & "regsvr32 " & Dir$(DLLPath)

' End If

Else

'RegisterServer frm.hwnd, DLLPath, False

RegisterServer frm.hWnd, temp & "\" & dir$(DLLPath), False

' If Dir$(GetSystemDir & "\regsrv32.exe") = "" Then

' Shell "regsvr32 /u " & Dir$(DLLPath)

' Else

' Shell App.Path & "\" & "regsvr32 /u " & Dir$(DLLPath)

' End If

End If

Exit Sub

ErrHandler:

ShowErrMsg

End Sub

Public Function RegisterServer(hWnd As Long, DllServerPath As String, bRegister As Boolean)

On Error Resume Next

' going to call the DllRegisterServer/DllUnRegisterServer API of the specified library.

' there's no need to use the Regsvr32.exe anymore.

' Make sure the path is correct and that the file exists, otherwise VB will crash.

Dim LB As Long, pa As Long

LB = LoadLibrary(DllServerPath)

If bRegister Then

pa = GetProcAddress(LB, "DllRegisterServer")

Else

pa = GetProcAddress(LB, "DllUnregisterServer")

End If

If CallWindowProc(pa, hWnd, ByVal 0&, ByVal 0&, ByVal 0&) = ERROR_SUCCESS Then

'MsgBox IIf(bRegister = True, "Registration", "Unregistration") + " Successful"

Else

'MsgBox IIf(bRegister = True, "Registration", "Unregistration") + " Unsuccessful"

End If

'unmap the library's address

FreeLibrary LB

End Function

in your form, try use it like: RegisterDLL Me, myDLLFilePath, True

and you can add the para of "/u" in regsvr32 to make it execute in silent mode:

Example: regsvr32 /u mydll.dll
