「メモ帳」に書き込む

以下のコードを実行すると、メモ帳に「こんにちは！」と書き込む。メモ帳はあらかじめ起動しておく必要がある。

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As String) As Long
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_SETTEXT = &HC

Private Sub Command1_Click()

    Dim hNotePad As Long
    Dim hEdit As Long

    hNotePad = FindWindow("NotePad", vbNullString)
    hEdit = FindWindowEx(hNotePad, 0, "Edit", vbNullString)
    Call SendMessage(hEdit, WM_SETTEXT, 0, ByVal "こんにちは！")

End Sub
