Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (
ByVal hWnd As Long,
ByVal wMsg As Long,
ByVal wParam As Long,
ByVal lParam As String
) As Long
說明
hWnd Handle to the window whose window procedure will receive the message
Msg [in] Specifies the message to be sent.
wParam [in] Specifies additional message-specific information.
lParam [in] Specifies additional message-specific information.
-----------------------------------------------
說明
S為空字串
(1)
SendMessage handle_x , WM_GETTEXT , S , Len(S)
Text1.Text = S
結果：Text1.text仍是空字串
------------------------------------------
改為
(2)
SendMessage handle_x , WM_GETTEXT , Len(S) , S
Text1.Text = S
結果：Text1.text抓到我要的內容
怎麼會這樣，是差在哪？
