Any ideas why I am getting an "Enter Parameter Value" input box when running this code?
Private Sub cmdPrint_Click()
Dim str As String
On Error GoTo ErrHandler
If IsNull(Me.Combo_1) Then
MsgBox "Can't print an unsaved record", _
vbOKOnly, "Error"
Exit Sub
End If
str = "Combo_1 = '" & Me!Combo_1 & "'"
Debug.Print str
DoCmd.OpenReport "rptBarCodeLabels(2)", acViewPreview, , str
Exit Sub
ErrHandler:
MsgBox Err.Number & ": " _
& Err.Description, vbOKOnly, "Error"
End Sub
Edit: The button is being used to print a label of what's currently selected in Combo_1. Once the print button has been clicked, I wanted it to display the single record I chose in the label report I have it referencing. I am using Access 2003 if that means anything.
If a field name in a query contains punctuation (Combo_1), you should enclose in brackets, like so:
str = "[Combo_1] = '" & Me!Combo_1 & "'"
The Report is expecting a parameter, but not getting it because it's not being passed through in the correct manner.
I've found a solution by using some coding that was provided here: http://www.techrepublic.com/article/how-to-print-one-or-more-labels-for-a-single-access-record/
What fixed the error was most likely creating a temporary table and temporary report.

I'm currently building a form where a user can look up a tool based on the description or part number.
I want user to be able to type any letters into the combobox that I have tied to a query listing all my tools and the combobox will repopulate itself with the tools most similar to what is present in their combobox. For example, if they start typing wre, then tools that have similar characters will start appearing in the combobox such as wrench, torque wrench, power wrench, etc.
I've tried looking around for other people's solutions to this but either I didn't fully comprehend the existing solution (I'm fairly new to Access) or it wasn't what I was looking for. I've seen that people suggested using a listbox instead but I really don't want to go down that route.
I was thinking about using what the user types in the combobox and my VBA code will pick up the "change event" and requery the combobox on the fly by using their input as the like criteria for the new query.
Is this a possible route? Will it be slower? Is there a better route?
I'm hoping someone can show some examples on how to achieve what I'm looking for.
The search as you type feature is very useful! With a textbox and a listbox, you can setup a dynamic search tool that will filter a list for approximate matches as you type. The textbox has four events associated with it, as seen here.
The code behind the form looks like this. Pay attention to the part in bold. This is where we create a string of SQL commands, and utilize the SQL Like operator, to get dynamic matches as we type. Pay attention to the text in bold below.

Private Sub txtSearch_Change()

Dim strFullList As String
Dim strFilteredList As String
If blnSpace = False Then
Me.Refresh 'refresh to make sure the text box changes are actually available to use
'specify the default/full rowsource for the control
strFullList = "SELECT RecordID, First, Last FROM tblNames ORDER BY First;"
'specify the way you want the rowsource to be filtered based on the user's entry
strFilteredList = "SELECT RecordID, First, Last FROM tblNames WHERE [First] LIKE ""*" & Me.txtSearch.Value &
"*"" OR [Last] LIKE ""*" & Me.txtSearch.Value & "*"" ORDER BY [First]"
'run the search
fLiveSearch Me.txtSearch, Me.lstItems, strFullList, strFilteredList, Me.txtCount
End If
End Sub
Private Sub txtSearch_KeyPress(KeyAscii As Integer)
'NECESSARY TO IDENTIFY IF THE USER IS HITTING THE SPACEBAR
'IN WHICH CASE WE WANT TO IGNORE THE INPUT
On Error GoTo err_handle
If KeyAscii = 32 Then
blnSpace = True
Else
blnSpace = False
End If
Exit Sub
err_handle:
Select Case Err.Number
Case Else
MsgBox "An unexpected error has occurred: " & vbCrLf & Err.Description &
vbCrLf & "Error " & Err.Number & "(" & Erl() & ")"
End Select
End Sub
Private Sub txtSearch_GotFocus()
' USED TO REMOVE THE PROMPT IF THE CONTROL GETS FOCUS
On Error Resume Next
If Me.txtSearch.Value = "(type to search)" Then
Me.txtSearch.Value = ""
End If
End Sub
Private Sub txtSearch_LostFocus()
' USED TO ADD THE PROMPT BACK IN IF THE CONTROL LOSES FOCUS
On Error Resume Next
If Me.txtSearch.Value = "" Then

End If
End Sub
Finally, in a regular module, you will need this script.

I have use "E "0000000000a;0;# in input mask and included this code to check if the employeeCode already exists in the Before Update.
But when i am trying to input a duplicate employee code. It's allowing it.
Any idea?
Private Sub Empl_Code_BeforeUpdate(Cancel As Integer)
If IsNull(DLookup("[EmplCode]", _
"FORM EMPLOYEE", _
"[EmplCode] = """ & Me.Empl_Code.Text & """")) = False Then
Cancel = True
MsgBox "Record already exists", vbOKOnly, "Warning"
Me![Empl Code].Undo
End If
End Sub
Your code looks legit.
Test your IsNull(DLookup... expression in Immediate window (View - Immediate window in VBA Editor) when you are trying to input a duplicate code.
Also you can shorten a bit your expression with DCount like that:
Private Sub Empl_Code_BeforeUpdate(Cancel As Integer)
If DCount("*", _
"FORM EMPLOYEE", _
"[EmplCode] = """ & Me.Empl_Code.Text & """") > 0 Then
Cancel = True
MsgBox "Record already exists", vbOKOnly, "Warning"
Me![Empl Code].Undo
else
' Just for test
MsgBox "Value: " & Me.Empl_Code.Text
End If
End Sub
Thanks in advance for your help.
I am not sure where the problem in my UDF but the excel restarts automatically after executing the program and also shows MsxBox twice with the reference value.
Public queryString As String
Public Function SetIt(RefCell) As String
On Error GoTo CatchBlock
MsgBox RefCell.Value
queryString = RefCell.Value
RefCell.Parent.Evaluate "SetValue(" & RefCell.Address(False, False) & ")"
GoTo Finally
CatchBlock:
MsgBox "Error " & Err.Number & ": " & Err.Description, vbCritical, "Error in Function"
Finally:
SetIt = ""
End Function
// For now I am trying to set the cell reference value in some other cell.
Sub SetValue(RefCell As Range)
RefCell.Offset(1, 1).Value = queryString
End Sub
I am still beginner and need to accomplish another big task based on this program code execution.
Please help !!
Excel 64 bit & Office 365 is my environment
I have a textbox that dynamically filters a listbox on the same form as you type. The listbox filters perfectly, but the selected value is not saving correctly. For example, if you click on the fourth value after filtering the listbox and then close the form, it actually saves what would have been the fourth value had the list not been filtered.
Here is the code:
Private Sub txtSearch_Change()
'CODE THAT HANDLES WHAT HAPPENS WHEN THE USER TYPES IN THE SEARCH BOX
Dim strFullList As String
Dim strFilteredList As String
If blnSpace = False Then
Me.Refresh 'refresh to make sure the text box changes are actually available to use
'specify the default/full rowsource for the control
strFullList = "SELECT [Project ID], [Project Name] FROM [Admin: Projects] ORDER BY [Project Name];"
'specify the way you want the rowsource to be filtered based on the user's entry
strFilteredList = "SELECT [Project ID], [Project Name] FROM [Admin: Projects] WHERE [Project Name] LIKE ""*" & Me.txtSearch.Value & "*"" ORDER BY [Project Name]"
'run the search
fLiveSearch Me.txtSearch, Me.lstItems, strFullList, strFilteredList, Me.txtCount
End If
End Sub
Private Sub txtSearch_KeyPress(KeyAscii As Integer)
'NECESSARY TO IDENTIFY IF THE USER IS HITTING THE SPACEBAR
'IN WHICH CASE WE WANT TO IGNORE THE INPUT
On Error GoTo err_handle
If KeyAscii = 32 Then
blnSpace = True
Else
blnSpace = False
End If
Exit Sub
err_handle:
Select Case Err.Number
Case Else
MsgBox "An unexpected error has occurred: " & vbCrLf & Err.Description & _
vbCrLf & "Error " & Err.Number & "(" & Erl & ")"
End Select
End Sub
Private Sub txtSearch_GotFocus()
' USED TO REMOVE THE PROMPT IF THE CONTROL GETS FOCUS
On Error Resume Next
If Me.txtSearch.Value = "(type to search)" Then
Me.txtSearch.Value = ""
End If
End Sub
Private Sub txtSearch_LostFocus()
' USED TO ADD THE PROMPT BACK IN IF THE CONTROL LOSES FOCUS
On Error Resume Next
If Me.txtSearch.Value = "" Then
Me.txtSearch.Value = "(type to search)"
End If
End Sub
Private Sub Form_Close()
DoCmd.SetWarnings False
End Sub
I've inherited this database and am trying to fix up areas that are not working. I'm definitely a novice and I can't seem to figure out where the error might be in the code that is causing the wrong value to save to the record. Any guidance would be appreciated.
Replace:
'run the search
fLiveSearch Me.txtSearch, Me.lstItems, strFullList, strFilteredList, Me.txtCount
With
me.lstitems.rowsourcetype = "Table/Query"
me.lstitems.rowsource = strfilteredlist
Please, HELP
I have a login form where Combo box contains 3 fields (EmployeeID, Employee Name: [FirstName] & " " & [LastName], JobTitle - qry picked). In dropdown list is only one field shown (properties set 0', 1', 0' width). Also frmLogin contains a text box to enter a password and there are two hidden text boxes (Name and JobTitle for other functions to perform). When I choose the UserName, hidden boxes are populated; however, when I enter password, the popup window shows up with Run-time error ‘2471’ - The expression you entered as a query parameter produced the following error: ‘admin’.
Here is a code to log in.
Private Sub cmdLogin_Click()
If IsNull(Me.cboLoginName) Or Me.cboLoginName = "" Then
MsgBox "You must select an employee name.", vbOKOnly, "Required data"
Me.cboLoginName.SetFocus
Exit Sub
End If
If IsNull(Me.tbxPassword) Or Me.tbxPassword = "" Then
MsgBox "You must enter a password", vbOKOnly, "Required data"
Me.tbxPassword.SetFocus
Exit Sub
End If
'next line is highlighted as error
If Me.tbxPassword.Value = DLookup("Password", "tblEmployees", "[EmployeeID]=" & Me.cboLoginName.Value) Then
Me.Visible = False
DoCmd.OpenForm "frmEntry"
Else
MsgBox "Invalid employee name / password combination. Please try again.", vbOKOnly, "Invalid Entry!"
Me.tbxPassword.SetFocus
End If
End Sub
Query for the combobox
Since I don't know the rowsource of your combobox or the number of columns your control specifies, paste the following code before your DLookup and see which column you should be using:
Dim i As Integer
For i = 0 To Me.cboLoginName.ColumnCount
Debug.Print "Column " & i & " contains '" & Me.cboLoginName.Column(i) & "'"
Next i
