查找窗口在64位VBA7中不工作

Question

在Unlocking Password Protected VBA project上显示的代码工作在32位以下，而不是64位。具体来说，

Ret = FindWindow(vbNullString, "VBAProject Password")

始终返回0。我试过了

Ret = FindWindow("#32770", "VBAProject Password")

Ret = FindWindow("XLMAIN", "VBAProject Password")

都不管用。我还尝试了以下API:setfore背景窗口、带窗口窗口、setfocus、getactivewindow、getactivewindow线程following。还是失败了所以我不认为这是个焦点问题。也许是时机问题？我试着用

SetTimer

但是我对API并不熟悉，所以我不知道如何实现它。

我是通过我的personal.xlsb内的workbookopen应用程序事件调用这个程序的，我试图在打开任何工作簿时输入密码。

Private Sub AppEvent_WorkbookOpen(ByVal wb As Excel.Workbook)

If wb.VBProject.Protection <> 1 Then
Exit Sub
End If

Call unlockvba(wb)

End Sub

编辑:如果适用的话，我已经将声明设置为PtrSafe和LongPtr。

Answer 1

弄明白了。问题不是64位，而是时间/焦点问题。

Sub unlockVBA(wb)

If wb.name = "PERSONAL.XLSB" Then Exit Sub

Application.VBE.MainWindow.Visible = True

TimerID = SetTimer(0&, 0&, 500&, AddressOf TimerProc)

Application.VBE.CommandBars(1).FindControl(ID:=2578, recursive:=True).Execute

End Sub

Public Sub TimerProc(ByVal hwnd As LongPtr, ByVal wMsg As LongPtr, ByVal idEvent As LongPtr, ByVal dwTime As LongPtr)

On Error Resume Next
KillTimer hwnd, TimerID

MyPassword = "password"

Ret = FindWindow(vbNullString, "VBAProject Password")
ChildRet = FindWindowEx(Ret, ByVal 0&, "Edit", vbNullString)
If ChildRet <> 0 Then
Call SendMessage(ChildRet, WM_SETTEXT, False, ByVal MyPassword)
DoEvents
End If

ChildRet = FindWindowEx(Ret, ByVal 0&, "Button", vbNullString)

If ChildRet <> 0 Then
'MsgBox "Button's Window Found"

'~~> Get the caption of the child window
strBuff = String(GetWindowTextLength(ChildRet) + 1, Chr(0))
GetWindowText ChildRet, strBuff, Len(strBuff)
ButCap = strBuff

'~~> Loop through all child windows
Do While ChildRet <> 0
    '~~> Check if the caption has the word "OK"
    If InStr(1, ButCap, "OK") Then
    '~~> If this is the button we are looking for then exit
    OpenRet = ChildRet
    Exit Do
    End If

    '~~> Get the handle of the next child window
    ChildRet = FindWindowEx(Ret, ChildRet, "Button", vbNullString)
    '~~> Get the caption of the child window
    strBuff = String(GetWindowTextLength(ChildRet) + 1, Chr(0))
    GetWindowText ChildRet, strBuff, Len(strBuff)
    ButCap = strBuff
Loop

If OpenRet <> 0 Then
'~~> Click the OK Button
SendMessage ChildRet, BM_CLICK, 0, vbNullString
Else
MsgBox "The Handle of OK Button was not found"
End If
Else
MsgBox "Button's Window Not Found"
End If
