ms-access - 非阻塞 "toast"类似 Microsoft Access (VBA) 的通知

Question

如何在 Microsoft Access 中显示非阻塞“toast”之类的通知？那确实有某种动画，不应该阻止主机应用程序!

Answer 1

我的 friend 问我关于非阻塞 toast 的问题，比如 ms Access 的通知。我的第一个想法是，检查谷歌你会发现很多样本。他对他得到的 sample 并不满意。

他想要类似(JQuery)非阻塞通知的东西。用户需要知道但不一定需要交互的东西。

由于在 VBA 中无法进行线程处理，我想，如果您可以编写自己的 .dll 会怎样？所以我最终编写了一个 .NET DLL，它可以被(windows)VBA 代码 Access 并显示一个 toast 通知。
(实际 dll 创建和从 vba Access .NET dll 是我稍后将介绍的另一个主题)( You can read more in my blog 根据您的意愿留下评论或建议。)

现在，您可以从这里下载我创建的 DLL:

如果您担心下载未知的 DLL:VirusTotal Scan report

将 DLL 添加到您的应用程序的根文件夹并将以下代码添加到您的应用程序。

'Module level public variable

Public gTOASTER As Object

' to save window metrics
Public Type RECT
    Left        As Long  ' x1
    Top         As Long  ' y1
    Right       As Long  ' x2
    Bottom      As Long  ' y2
End Type

#If VBA7 Then 
    Public Declare PtrSafe Function LoadLibrary Lib "kernel32" Alias "LoadLibraryA" (ByVal lpLibFileName As String) As LongPtr
    Public Declare PtrSafe Function KRISH_VBA_TOOLS Lib "VBA_TOOLS.dll" () As Object
    Public Declare PtrSafe Function GetWindowRect Lib "user32" (ByVal hWnd As LongPtr, ByRef lpRect As RECT) As LongPtr 
#Else
    Public Declare Function LoadLibrary Lib "kernel32" Alias "LoadLibraryA" (ByVal strFilePath As String) As Long
    Public Declare Function KRISH_VBA_TOOLS Lib "VBA_TOOLS.dll" () As Object
    Public Declare Function GetWindowRect Lib "user32" (ByVal hWnd As LongPtr, ByRef lpRect As RECT) As LongPtr
#End If

Public Function FN_TOAST_DLL(iMessage As String, Optional iCLOSE_DURATION As Long = 3000, Optional iType As String = "success", Optional iANIME_DURATION As Long = 1000, Optional iFONT_COLOR As String = "#FFFFFF", Optional iX As Long = 0, Optional iY As Long = 0, Optional iANIME_DIRECTION As Integer = 1, Optional iPARENT_HWND As Long = 0)

On Error GoTo LABEL_EXIT_ROUTINE:

    If gTOASTER Is Nothing Then
        LoadLibrary (FN_APP_GET_BASE_PATH & "VBA_TOOLS.dll")
        Set gTOASTER = KRISH_VBA_TOOLS()
        GoTo LABEL_TOAST
    Else
        GoTo LABEL_TOAST
    End If

    On Error GoTo 0
    Exit Function

LABEL_EXIT_ROUTINE:
    msgbox iMessage & vbnewline & err.description
    Exit Function

LABEL_TOAST:
    'set background color. (pass any html color code)
    Select Case iType
        Case "error"
            iType = "#F76160"
        Case "success"
            iType = "#26ad82"
        Case Else
            iType = "#26ad82"
    End Select

    'if parent object is provided show the toast on top of the parent. if custom x, y is provided use x,y coordinated. if none provided use access app's locaiton.
    Dim mRect As RECT
    If iPARENT_HWND <= 0 Then
        If iX = 0 And iY = 0 Then
            GetWindowRect Application.hWndAccessApp, mRect

            iANIME_DIRECTION = 0 'anim direction 0 to down and 1 to up
        End If
    Else ' iPARENT_HWND > 0 Then 'parent_hwnd is null
        GetWindowRect iPARENT_HWND, mRect
    End If

    'set up some offsets
    iX = mRect.Left + 360
    iY = mRect.Top + 1


    On Error Resume Next
    gTOASTER.FN_SHOW_TOAST iMessage, iCLOSE_DURATION, iType, iANIME_DURATION, iFONT_COLOR, iX, iY, iANIME_DIRECTION

End Function

Public Function FN_APP_GET_BASE_PATH()
    Dim FN As String
    FN = Application.CurrentProject.path
    If VBA.Right(Application.CurrentProject.path, 1) <> "\" Then FN = FN & "\"
    FN_APP_GET_BASE_PATH = FN
End Function

如果要自定义 fn_toast_dll 函数，请从 DLL 中获取参数列表:

'    /// <summary>
'    ///
'    /// </summary>
'    /// <param name="iMessage">Message to display</param>
'    /// <param name="iDuration">Duration in Milliseconds to keep the toast before fading out..</param>
'    /// <param name="iBG_COLOR">HTML color code for your toast background...</param>
'    /// <param name="iANIME_DURATION">Millisecond value used to for fading in and out the Toast.. 1/4 is used to fade in rest to fade out..</param>
'    /// <param name="iFONT_COLOR">HTML Color code for the font..</param>
'    /// <param name="iX">x position on the screen. where the toast should appear</param>
'    /// <param name="iY">y position on the screen where the toast should appear</param>
'    /// <param name="iANIM_DIRECTION">{0,1} 0 will show/add further notifications downwards and 1 upwards.</param>
'    /// <returns></returns>

显示通知调用此方法:

FN_TOAST_DLL "hello this is a green test" ' By default a success message with 3 seconds will be "toasted"
FN_TOAST_DLL "hello this is an error", 15000, "error"

用法 :

您可以将其用于任何非交互警报......例如登录成功，或操作取消警报或用户不需要按 OK 确认您的消息的任何内容。
