Excel VBAで他アプリへのテキストデータ貼り付け

#1です。

いい加減にしろと、お叱りを受けそうですが、別の方法をWEBでみつけました。元は他のアプリをスクロールするコードなのですが、アレンジしてみました。このコードだと、複数起動したメモ帳に、ワンクリックで貼り付けられます。マウス動作をフックするため、左クリックでUserFormが閉じられませんので、ALT+F4で閉じて、テキスト貼り付けを終了してください。なお、貼り付けエラーを検出しようとしてうまくいっていません。

#1,#3です。

もう誰も見ていないと思いますが、「自アプリケーション外のマウスのイベントを拾える様にするAPI」を、VBAで使う方法を模索していて、以前断念した、VBAからCreateWindowを使う方法を再度調べてみると、みつけてしまいました。これで、真っ当な？Windowが作れますので、上記APIが使えます。
下記コードの使い方は、貼り付けたいデータ列の最初のセルをアクティブにし、mainを実行すると、ウィンドウが表示されます。click hereと表示されたらそのボタンをクリックし、click controlと表示されたら、貼り付け先のコントロールをクリックします。メモ帳を沢山表示させておいて実行したら動作しました。メモ帳→エクセルをアクティブにするのがうまくいかないので、都度ボタンをクリックするという２アクションになってしまいます。Windowを消さずにVBAを終了させるとフリーズする等、色々と不安定なところがあり、趣味の世界です。VBAでWin32プログラミングもおつではないでしょうか。

#1です。

少々遊んでみました。拙い切り貼りで識者からは笑われそうですが、
１．ワークシートにコマンドボタンを一個置いて、シートモジュールに下記のコードを書き込みます。
Private WithEvents myTimer As myTimerClass
Private Declare Function GetClassName Lib "USER32" Alias "GetClassNameA" (ByVal hWnd As Long, ByVal lpClassName As String, ByVal nMaxCount As Long) As Long
Private Declare Function WindowFromPoint Lib "user32.dll" (ByVal x As Long, ByVal y As Long) As Long
Private Declare Function GetCursorPos Lib "USER32" (lpPoint As POINTAPI) 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 Type POINTAPI
x As Long
y As Long
End Type

Private Const WM_PASTE As Long = &H302
Private Const WM_CLEAR As Long = &H303
Private Const EM_SETSEL = &HB1

Private Sub CommandButton1_Click()
Set myTimer = New myTimerClass
Call myTimer.TimerTask(1000)
DoEvents
End Sub

Private Sub mytimer_UpdateTime(ByVal lngJump As Long)
Dim nhWnd As Long
Dim ClassName As String * 255
Dim Poi As POINTAPI
Dim lngRet As Long
Dim wName As String

GetCursorPos Poi
nhWnd = WindowFromPoint(Poi.x, Poi.y)
Call GetClassName(nhWnd, ClassName, 255)
　　wName = Left(ClassName, InStr(ClassName, Chr(0)) - 1)
Debug.Print wName
If wName = "XLMAIN" Then Exit Sub
Select Case wName
Case "Edit"
lngRet = SendMessage(nhWnd, EM_SETSEL, 0, -1)
lngRet = SendMessage(nhWnd, WM_CLEAR, 0, 0)
lngRet = SendMessage(nhWnd, WM_PASTE, 0, 0)
End Select
End Sub
２．クラスモジュールmyTimerClassを定義します。
Public Event UpdateTime(ByVal lngJump As Long)
Private Declare Function GetTickCount Lib "kernel32" () As Long

Public Sub TimerTask(ByVal Duration As Long)
Dim lngStart As Long

lngStart = GetTickCount
Do While GetTickCount < lngStart + Duration
Loop
RaiseEvent UpdateTime(GetTickCount - lngStart)
End Sub
３．使い方
適当なセルの内容等をコピーした後、コマンドボタンをクリックし、他のアプリケーションのEditコントロールの上にマウスポインタを置きます。クリックしてから1秒後にマウスポインタがあるEditコントロールの内容を消去して、クリップボードの中味を貼り付けます。相手がメモ帳程度なら動作しました。相手のコントロールのクラス名を、Debug.Printする様になっていますので、相手に応じて拡張可能です（物好きな方はどうぞ）。相手によっては、ハンドルを取得できない事もある様です。
（注）自アプリケーション外のマウスのイベントを拾える様にするAPIを、VBからは使える様ですが、VBAのフォームからは無理な様です。という事で、VBAのヘルプのサンプルを改造した怪しげなタイマーを使っています。
これが呼び水になって達人の方々の反応があると嬉しいです。

こんばんは。

直接の解答にはなりませんが、#1さんのリンク先のsendmessage か、postmessage か、どちらかを使うのが良いのですが、問題は、

「他アプリケーション（Excelの次にアクティブな状態）のテキストボックス」
のハンドルが取れないことには、難しいのではないかと思います。

それをするためには、Spy++ などのツールが必要です。(擬似ツールは、Vectorにあります）テキストボックス自体はそのままでも、そのアプリケーション自体を決めなくてはなりません。

そういうのが出来なって思うなら、うみうみ屋さんの、UWSCがあります。
この中に、すでに、Win32 APIと同様の機能も含まれていますが、Win32 APIのような難しい書き方は必要ありません。後は、位置関係だけ動かさなければ、そのまま、キーボードマクロが完成します。Excelから呼び出すことも可能です。

このマクロのプログラミングは、VBAの出来る方なら簡単に出来ますが、記録マクロも可能です。

http://www.uwsc.info/

なお、このシェアウェアは、会社でも正規ツールとして認められるものです。

こちらがご参考になるのではないでしょうか。

> C# のスレッドなのに VB でサンプルコードを書いてしまいました。
だ、そうですし。APIを使うのは一緒だと思いますので。
