【问题描述】:
我正在使用 Excel 2016,而且我是 VBA 新手。用户表单initialize 功能正常工作,然后停止。我正在尝试找出原因。
我想在工作表上按下一个按钮,弹出一个接受一些输入(文本和下拉列表中的选择)的表单,以及表单上的另一个按钮来创建另一个弹出窗口以接受更多输入(条形码扫描或文本输入)直到它最终根据确定的条件退出(用完扫描的条形码填充插槽)或用户退出。
我在工作表上有按钮。我有用户表单。但是,在某些时候,我不得不将 userform_Initialize 重命名为 <formName>_Initialize,因为我收到了有关缺少对象的错误,以及错误 424。这样做之后,“编译器”很高兴,但从未调用过初始化函数,所以用户表单上没有任何工作。
我认为我看到的内容与 this other question 非常相似,但我不确定,如果我尝试这样做,我也不确定在哪里粘贴我的代码。
我是否采取了错误的方法?
Private Sub UserForm_Initialize() 在我单击命令按钮以调出用户窗体时在运行时给出错误 424。切换到Private Sub warehouseCheckinForm_Initialize(),在填充用户表单时永远不会调用初始化函数,从而导致表单上的功能损坏并导致其他问题..
这是用户窗体上的代码:
Public initialsInput As String
'*Initials of user scanning in stuff
Public modelSelected As String
'*Model selected for scanning
Public numItemsModel As Integer
'*Keep track of how many of the selected model are available to check in to the warehouse
Public searchBOMRange As Range
'*Range for search operations
Private Sub ModelComboBox_Change()
modelSelected = ModelComboBox.Value
numItemsModel = Application.WorksheetFunction.CountIf(searchBOMRange, modelSelected)
numItemsModelLabel.Caption = numItemsModel
End Sub
Private Sub setInitialsButton_Click()
If Len(InitialsTextBox.Value) = 2 Then
initialsInput = InitialsTextBox.Value
ElseIf Len(InitialsTextBox.Value) < 2 Then
MsgBox "Enter in 2 letters for your initials"
Else
MsgBox "You entered in too much data!"
End If
End Sub
Private Sub UserForm_Initialize()
'*Start with empty inputs
numItemsModel = 0
searchBOMRange = Sheets("BOM").Range("C11:C2000")
modelSelected = ""
initialsInput = ""
InitialsTextBox.Value = ""
ModelComboBox.Clear
numItemsModelLabel.Caption = numItemsModel
'*Fill the Combo Boxes
Dim oDictionary As Object
Dim cellContentModel As String
Dim rngComboValues As Range
Dim rngCell As Range
Set rngComboValues = Sheets("BOM").Range("C11:C2000")
'*The first ~2000 items because there probably won't be BOMs bigger than that. Test case was <1000
'*Doing C:C took 5+ seconds to load the window
Set oDictionary = CreateObject("Scripting.Dictionary")
For Each rngCell In rngComboValues
cellContentModel = rngCell.Value
If Not oDictionary.exists(cellContentModel) Then
oDictionary.Add cellContentModel, 0
End If
Next rngCell
For Each itm In oDictionary.keys
Me.ModelComboBox.AddItem itm
Next itm
Set oDictionary = Nothing
'For Each cell In Sheets("BOM").Range("B:B")
' If cell.Value <> "" Then
' MakeComboBox.AddItem cell.Value
' End If
'Next cell
End Sub
Private Sub warehouseScanButton_Click()
For Each modelSelected In searchBOMRange
If Len(initialsInput) < 2 Then
Beep
MsgBox "Enter your initials first!"
End
ElseIf Len(modelSelected) < 1 Then
Beep
MsgBox "Select a model first!"
End
ElseIf Len(initialsInput) >= 2 And Len(modelSelected) >= 1 Then
scannedInput = InputBox("Scan a serial number, or type it in and mash the ENTER key")
If scannedInput = "NA" Or scannedInput = "N/A" Then
Beep
MsgBox "You can't search for 'not applicable', it doesn't apply!"
End
End If
End If
'//Searches for empty serial number cell
'// Model is in C, serial is in O (letter)
'//offset is row, column; down is positive, right is positive
Set matchedCell = modelSelected.Offset(0, 12)
If matchedCell Is Nothing Then
'//do stuff
scannedInput = InputBox("Scan a serial number, or type it in and mash the ENTER key")
matchedCell.Offset(0, 2).Value = initialsInput
matchedCell.Offset(0, 3).Value = Now '// Checked in to Warehouse
matchedCell.Offset(0, -2).Value = Now '// "Recv'd date"
matchedCell.Offset(0, 1).Value = "W"
numItemsModel = numItemsModel - 1
'If Len(matchedCell.Offset(0, 4).Value) >= 2 And scannedInput <> "" Then
' Beep
' MsgBox "Serial Number " & scannedInput & " is already checked in to The Lab!"
'ElseIf Len(matchedCell.Offset(0, 4).Value) < 2 Then
' matchedCell.Offset(0, 4).Value = initialsInput
' matchedCell.Offset(0, 5).Value = Now
' matchedCell.Offset(0, 1).Value = "L"
End If
If Not matchedCell Is Nothing Then '//If the cell has something in it
'//Beep
'//MsgBox "Error! This is unpossible!"
'//End
End If
End If
Next modelSelected
End Sub
这是工作表上命令按钮的逻辑:
Private Sub WarehouseCheckinCommandButton_Click()
'*Brings up the form
WareHouseCheckinForm.Show
End Sub
我认为以某种方式涉及关键字或其他内容。当我更改函数的名称时,我看到窗口顶部的一些内容发生了变化。它从“用户表单”到“常规”。我认为这很重要。
编辑 2
(编辑 1 是偷偷加入的)好的,听起来我需要将初始化函数保留为 Userform_Initialize。这是我单击命令按钮run time error 91 object variable or With block variable not set 时得到的结果,我可以选择调试。如果我调试,我会得到这个:

您是否厌倦了使用“Private Sub UserForm_Activate()”?或在您的循环之前添加“On Error resume next”,然后在循环之后添加“On error goto 0”。我知道这不是最安全的解决方法,但它可以帮助缩小您真正的问题所在。打开弹出窗口时也可以尝试“WareHouseCheckinForm.Show False”。希望有帮助

你说的我都不知道该怎么办了。

我无法理解您通过重命名子来修复错误 424 的想法。 VBA 中的事件处理程序必须具有特定名称,这就是它们被理解为事件处理程序的方式。在上一个屏幕截图中,您可以在左侧下拉列表中看到
UserForm,在右侧下拉列表中看到Initialize,这就是您知道 sub 是 事件处理程序的方式。您永远不会手动键入事件处理程序名称,您从两个下拉列表中选择事件并为您生成名称。重命名 sub 并以适当的方式修复您遇到的任何错误。 -
将
Option Explicit作为代码模块的第一行。 -
@DanWhaley:小提示:您不应该将解决方案放入问题中。由于您已经发布了相应的答案,因此它也是多余的。
