我的朋友问我关于ms访问的非阻塞吐司通知.我的第一个想法是,检查谷歌你会发现大量的样本.他对他得到的样品不满意.
他想要(JQuery)非阻塞通知.用户需要知道但不一定需要互动的东西.
由于在VBA中无法进行线程化,我想,如果你能编写自己的.dll怎么办？所以我最终编写了一个.NET DLL,可以通过(windows)VBA代码访问并显示Toast通知.
(实际的dll创建和从vba访问.NET dll是我将在稍后介绍的另一个主题)(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：

编辑：以上下载链接和GitHub链接已更新为我认为属于作者的工作链接.
如果您担心下载未知的DLL：VirusTotal Scan report
将DLL添加到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

#If VBA7 Then

#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)

Set gTOASTER = KRISH_VBA_TOOLS()
GoTo LABEL_TOAST

End If
On Error GoTo 0
Exit Function

End Select

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,则从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>
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"

您可以将此用于任何非交互式警报,例如登录成功,操作取消警报或任何用户无需按OK确认您的消息.
目标
我将在GitHub上传Dll项目,并请求其他VBA C#专家的贡献,使其更加更加漂亮,并且可供所有VBA开发人员使用.
