send enter key or chr(13) to the external form or messagebox

i am using third party control in my application. that is a .ocx file. when i run the application everytime it shows messagebox / form, when i press enter then it goes ahead with the application.

how can i send enter key through code. so that i dont need to press enter every time.

PopupHwnd will be the handle of the button

Code:

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long

Private Const WM_CHAR = &H102

Call SendMessage(PopupHwnd,WM_CHAR,13,0&)

Code:

Private Declare Function BringWindowToTop Lib "user32.dll" (ByVal hwnd As Long) As Long

Private Sub Command1_Click()
BringWindowToTop hWnd '/// THE OTHER APPLICATIONS HANDLE.
SendKeys "{ENTER}"'/// send the enter key to that window to close the messagebox.
End Sub

in that instance i had a seperate application open with a messagebox saying "loaded!" , then from my vb project i clicked Command1 and closed the messagebox.
hope that helps.
