剪貼簿複製、貼上 文字 for VB
VB.Net 個人不知
這裡適用的是 VB 6以下
一般來講VB要用
剪貼簿複製、貼上 的功能是
Clipboard.GetText
Clipboard.SetText
但如果你要複製的是 日文、簡中...等非 Big5碼 文字
一去一來下 就會多出幾個 ?號
因為 使用Windows 2000/XP 時
系統 <-剪貼簿-> VB APP
剪貼簿會把文字在Unicode 跟ANSI 之間轉來轉去。
如此一些在 Big5字碼裡沒有的字碼
就會變成 ?號
(比如 ウェブ全体から検索 會變成 ???全体??検索)
那如何避免呢？
此時我們選擇捨棄VB的 剪貼簿類
改用API 來個記憶體運作
先看程式
PHP 語法:
Public Function ClipboardCopy_String(hwnd As Long, strText As String, Mode As Integer)
Dim hMemory As Long 'handle
Dim lpMemory As Long '位址
If Mode = 0 Then GoTo SETCLIP
'**獲取剪貼簿裡的字串
If OpenClipboard(hwnd) Then '開啟剪貼簿
hMemory = GetClipboardData(CF_UNICODETEXT) '以UniCode文字格式獲取剪貼簿裡的字串
If hMemory Then '成功獲取的話
lpMemory = GlobalLock(hMemory) '獲取該記憶體位址 (藉由handle)，並鎖住該記憶體空間
strText = Space(lstrlenW(lpMemory) * 2) '配置給字串變數 一固定長度
lstrcpyW StrPtr(strText), ByVal lpMemory '將前面記憶體內容 複製到 字串變數裡
GlobalUnlock hMemory '解鎖記憶體位址
End If
End If
GoTo EXITFUN
'**將字串放入剪貼簿裡
SETCLIP:
If OpenClipboard(hwnd) Then '如果可以開啟剪貼簿的話
EmptyClipboard '清空剪貼簿
strText = strText & vbNullChar '字串尾接一個API字串用 結束識別字元
Mode = LenB(strText) '該字串的長度
hMemory = GlobalAlloc(GHND, Mode) '配置一個 記憶體空間，並獲得 控管ID
If hMemory Then '前一行可行的話...
lpMemory = GlobalLock(hMemory) '與之前敘述雷同
lstrcpyW ByVal lpMemory, StrPtr(strText) '與前敘述雷同，StrPtr是獲取字串之記憶體位址 之VB保留字
GlobalUnlock hMemory '與前敘述雷同
SetClipboardData CF_UNICODETEXT, hMemory '設定hMemory控管的內容 給 剪貼簿，格式是UniCode文字
End If
EXITFUN:
CloseClipboard '關閉剪貼簿的使用
End If
End Function
如何使用
Dim ts As String
ClipboardCopy_String 0, ts, 1 '得到剪貼板的字 到 ts
ClipboardCopy_String 0, ts, 0 '貼ts 到 剪貼板
而
ClipboardCopy_String 0, ts, 0
可以
Clipboard.SetText ts
替換之
P.S. 因為 ts 是Unicode格式， Unicode字串傳給 剪貼板 同樣都是Unicode，正常來說不會有 ?號 字元之問題產生，當然如要避免萬一，建議直接用 ClipboardCopy_String 會比較保險
這裡有用到不少 API函式 及 常數
