VBプロジェクトをvbマクロから保護解除するにはどうすればよいですか?このコードを見つけました:
Sub UnprotectVBProject(ByRef WB As Workbook, ByVal Password As String)
Dim VBProj As Object
Set VBProj = WB.VBProject
Application.ScreenUpdating = False
'Ne peut procéder si le projet est non-protégé.
If VBProj.Protection <> 1 Then Exit Sub
Set Application.VBE.ActiveVBProject = VBProj
'Utilisation de "SendKeys" Pour envoyer le mot de passe.
SendKeys Password & "~"
SendKeys "~"
'MsgBox "Après Mot de passe"
Application.VBE.CommandBars(1).FindControl(ID:=2578, recursive:=True).Execute
Application.Wait (Now + TimeValue("0:00:1"))
End Sub
ただし、このソリューションはExcel 2007では機能しません。IDEで認証のウィンドウと印刷パスワードを表示します。
次に、私の目標は、このウィンドウを表示せずにVBprojectの保護を解除することです。
助けてくれてありがとう。
[〜#〜] edit [〜#〜]:
これをVBAおよびVB.Netの BLOG投稿 に変換しました。
私はSendkeys
に賛成したことがありません。信頼できる場合もありますが、常にではありません。 APIのソフトコーナーがあります。
目的は達成できますが、VBAの保護を解除するワークブックを別のExcelインスタンスで開く必要があります。
ここに例があります
現在、このようなVBAプロジェクトのワークブックがあるとします。
[〜#〜] logic [〜#〜]:
FindWindow
を使用して、「VBAProject Password」ウィンドウのハンドルを見つけます
それが見つかったら、FindWindowEx
を使用してそのウィンドウで編集ボックスのハンドルを見つけます。
編集ボックスのハンドルが見つかったら、SendMessage
を使用して書き込みます。
Buttons
を使用して、そのウィンドウでFindWindowEx
のハンドルを見つけます。
OK
ボタンのハンドルが見つかったら、SendMessage
を使用してクリックします。
[〜#〜]推奨[〜#〜]:
APIの場合 [〜#〜] this [〜#〜] は、私が推奨できる最高のリンクです。
FindWindow
、FindWindowEx
、SendMessage
のようなAPIを使いたい場合は、システムのプロセス、スレッド、ウィンドウ、ウィンドウをグラフィカルに表示するツールを入手してください。メッセージ。例:uuSpyまたはSpy ++。
Spy ++が「VBAProject Password」ウィンドウに表示するものは次のとおりです。
[〜#〜]テスト[〜#〜]:
新しいExcelインスタンスを開き、以下のコードをモジュールに貼り付けます。

新しい答えのためにこれをロックしたことは知っていますが、上記のコードにはいくつかの問題があり、主にOffice 64ビット(VBA7)で作業しています。ただし、Excelの現在のインスタンスでコードが機能するように作成し、もう少しエラーチェックを追加し、UnlockProject
メソッドのみを公開して別のモジュールに貼り付けるようにフォーマットしました。
完全な開示のために、私は実際には この投稿 のコードから始めましたが、これはテーマのバリエーションです。
また、このコードは条件付きコンパイル定数も示しているため、32ビットと64ビットの両方のExcelを同時に使用できるようにする必要があります。 このページ を使用して、これを理解しやすくしました。
とにかくここにコードがあります。誰かがそれを役に立つと思うことを望みます:
