I have a VBA Access userform. In this useform there is a textbox with the name txtSearch_POBOX. I'm trying to get its value using the code below:
Private Sub txtSearch_FirstName_Change()
MsgBox ([Form_Client List].txtSearch_POBOX.Value)
End Sub
But this is constantly returning NULL. When even when there is a value inside the text box. Any ideas?
Your reference is wrong. It should read:
MsgBox Forms![Client List]!txtSearch_POBOX.Value
As it could be empty, you should use:
MsgBox Nz(Forms![Client List]!txtSearch_POBOX.Value)
remember that if you want to intercept the text box value while digiting, until you "validate" the content change (e.g. losing focus) the .Value property is not updated.
For instance I used a text box to make a running filter of a submask: I wanted to filter the submask while digiting.
To do this you need to use the .Text property.
In the following example I make a running filter of a list of Publishers:
Private Sub txtNameFilter_Change()
On Error Resume Next
Dim strFilter As String
If Not IsNull(Me.txtNameFilter.Text) Then
strFilter = "Publisher LIKE '*" + Me.txtNameFilter.Text + "*'"
Me.Filter = strFilter
Me.FilterOn = True
Me.txtNameFilter.SelStart = Len(Me.txtNameFilter.Text)
End If
End Sub

I have a text box called [Status] that a user can populate using a combo box.
I want to filter my form based on two potential values in the text box value - Pipeline or Forecast. The filter is activated by a checkbox. Click check box get records where the [Status] is either Pipeline or Forecast.
The checkbox code is easy enough. I am having trouble getting Access to filter on two possible values in the same text box.
I've tried
Private Sub checkboxFilterActive_AfterUpdate()
If checkboxFilterActive = True Then
Me.Filter = "[status]='Pipeline'" And "[status]='forecast'" 'Filter Code
Me.FilterOn = True
Else
Me.FilterOn = False
End If
End Sub
This throws a type mismatch error.
I've tried
Private Sub checkboxFilterActive_AfterUpdate()
Dim strFilter As String
strFilter = "[Status]='Forecast'" & "'AND [Status] = 'Pipeline'"
If checkboxFilterActive = True Then
DoCmd.ApplyFilter , strFilter
Else
DoCmd.ShowAllRecords
End If
End Sub
This throws a Syntax error (missing operator) query expression error.
Any help is much appreciated.
Use OR instead of AND. Also, OR operator is literal text and needs to be within quote marks to build criteria string.
Me.Filter = "[status]='Pipeline' OR [status]='forecast'" 'Filter Code
I have an Access 2016 DB 64bits contain related tables with a search split form that have an txtBox that filtered records accoring to its entered value.
Every thing is just fine with that for months and with thousands of records.
When I want to make it more proffesional to deploy it to other users by re-writing another similar DB but with 32bts Access 2016 and SPLIT it from the start into Tables Back-end and a Front end, the search form didn't show any record when I fire a searching parameter in the after update event!
the search form is linked to a query, I change it to a new one, also try to link the form directly to only one table for testing also not goes right, shows zero results.
when remove the filter, all records showing up again.
when I change the filter directly from the form properties it also fail for string search but when search for a primary key in a form control holding it its working just fine. ( search for Strings show no results, search for Numbers ( ex ID value, show correct results).
And Very strange, when I build another new DB (Same access application) just for testing for what is going on, with a form and joined to split back end tables and a textbox in the form to enter keywords to show the all related records in the that split form, it works fine, both for strings and for numbers?
Private Sub txtSearch_AfterUpdate()
Dim strFilter As String
On Error Resume Next
If Me.txtSearch.Text <> "" Then
strFilter = "[Complaints] Like '*" & Me.txtSearch.Text & "*'"
Me.Filter = strFilter
Me.FilterOn = True
Else
Me.Filter = ""
Me.FilterOn = False
End If
With Me.txtSearch
.SetFocus
.SelStart = Len(Me.txtSearch.Text)
End With
End Sub
when put a string into the txtsearch box , the code must search for any string with in [Complaints] similar to it and shows the records holding it.
with me it works in the old DB 64bits Not splitted, but its not working for the new DB 32bits split to back and front ends.
Be careful using .Text as it requires the control to have focus. So try:
Private Sub txtSearch_AfterUpdate()
Dim strFilter As String
' On Error Resume Next ' Don't use while debugging.
If Nz(Me!txtSearch.Value) <> "" Then
strFilter = "[Complaints] Like '*" & Me!txtSearch.Value & "*'"
Me.Filter = strFilter
Me.FilterOn = True
Else
Me.Filter = ""
Me.FilterOn = False
End If
With Me!txtSearch
.SetFocus
.SelStart = Len(.Value)
End With
End Sub
I have a textbox for username. The format is firstname.lastname and I am trying to check to see if the box has a "." in the name to validate the string. The messagebox works correctly, but whenever "Ok" is clicked, it still goes to the next textbox instead of going back to the txt_Name to edit the name entry.
Private Sub txt_Name_AfterUpdate()
Dim username As String
username = UCase(Me.txt_Name.Value)
Me.txt_Name.Value = username
If InStr(1, txt_Name.Text, ".", vbTextCompare) > 0 Then
Me.cb_Shift.SetFocus
Else
MsgBox ("Please use the following format:" & vbCrLf & _
"FirstName.LastName")
Me.txt_Name.SetFocus
End If
End Sub
For such kind validations please use BeforeUpdate event and set Cancel variable to True if the value is invalid. You won't need SetFocus in this case
Does anyone knows how to filter reports the right way within Access runtime mode?
The usual code with DoCmd doesn't work.
This is what I tried for the report:
Private Sub Befehl217_Click()
DoCmd.OpenReport "Tagesbericht", acViewPreview
End Sub
Private Sub Bezeichnungsfeld26_Click()
DoCmd.GoToControl "DateFilter"
DoCmd.RunCommand acCmdFilterMenu
End Sub
This didn't work. Access complained that "FilterMenu isn't available".
I tried to create a context menu but this only displayed me cut, copy and paste.
You confirmed your report includes a control named Bezeichnungsfeld26 and when the user clicks in that control, you want to bring up the filter menu for that control.
When the user clicks in that control, it has the focus, so there is no need for GoToControl. And you don't want to go to a different control if you want the user to filter on Bezeichnungsfeld26.
Disable the GoToControl line ...
Private Sub Bezeichnungsfeld26_Click()
'DoCmd.GoToControl "DateFilter"
DoCmd.RunCommand acCmdFilterMenu
End Sub
You can use the Filter property:
Me.Filter = "[YourField] = " & somevalue & ""
Me.FilterOn = True
or, to expand on your current method:
DoCmd.OpenReport "Tagesbericht", acViewPreview, , "[YourField] = " & somevalue & ""
If you filter for a date you must pass a properly formatted string expression for the date:
Dim FilterDate As Date
FilterDate = Date
DoCmd.OpenReport "Tagesbericht", acViewPreview, , "[DateFilter] = #" & Format(FilterDate, "yyyy\/mm\/dd") & "#"
So this code is meant to serve as a simple search system to go to certain records in a recordset. I originally had it so they had to click the btnGoToID button in order to perform the search. I decided to just make it a little more user friendly and make it so the search field listened for the Enter button and that would perform the search as well.
The issue that I am running into when the code gets to strID = Trim(Nz(Me.txtSearch.Value, "")) the value will randomly come back as an empty string even though visually I can see that there is a value in the textbox.
I haven't been able to narrow down any pattern for when this issue occurs. At this point I don't really even know how to troubleshoot this problem, nor the words to search for that could yield any results in Google. All I can say is that it SEEMS like changing between records will affect whether or not the search goes through.
This has always worked up until I put in the txtSearch_KeyPress sub procedure.
'============================================================================
' txtSearch_KeyPress
'============================================================================
Private Sub txtSearch_KeyPress(KeyAscii As Integer)
'If user pressed enter
If KeyAscii = 13 Then
Call btnGoToID_Click
End If
End Sub
'============================================================================
' btnGoToID_Click
'============================================================================
' <<Purpose>>
' Allow the user to search for a specific ID
'============================================================================
Private Sub btnGoToID_Click()
On Error GoTo Err_Handler
Dim rs As Recordset
Dim strID As String
Set rs = Me.RecordsetClone
strID = Trim(Nz(Me.txtSearch.Value, ""))
If (strID <> "") Then
'Go to the ID
rs.FindFirst "ID = '" & strID & "'"
If rs.NoMatch Then
MsgBox "ID does not exist"
Else
'If we have a match, set the record as the current record
Me.Bookmark = rs.Bookmark
End If
Else
MsgBox "Please enter a valid ID.", vbOKOnly, "Invalid ID"
End If
Exit_Handler:
On Error Resume Next
Me.txtSearch.Value = ""
rs.Close
Set rs = Nothing
Exit Sub
Err_Handler:
Call LogError(Err.Number, Err.Description, "txtSearch on " & Me.Name)
Resume Exit_Handler
End Sub
After the conversation in the comments I have narrowed down this question to be a whole lot simpler. This yields an "Invalid use of null" error message even after there are several characters in the text field. Why would that happen, and what can I do to make it pick up the values in the textbox?
'============================================================================
' txtUnitNoToSearch_KeyPress
'============================================================================
Private Sub txtUnitNoToSearch_KeyPress(KeyAscii As Integer)
MsgBox Me.txtUnitNoToSearch
End Sub
I think your problem is related to the fact that a text box has 2 properties, .Value and .Text, which appear similar but behave differently.
While you have an edit in progress in the text box, the changing content is available via the .Text property. However, the content of the .Value property has not yet been updated to match.
After the text box's After Update event, .Value will contain the new content. And if focus has moved away from the text box, its .Text property will no longer even be available.
Sorry, I couldn't think how to explain that better. But I think the situation will be clearer with this KeyPress event procedure:
Private Sub txtUnitNoToSearch_KeyPress(KeyAscii As Integer)
Debug.Print "Text: '" & Me.txtUnitNoToSearch.Text & "'"
Debug.Print "Value: '" & Me.txtUnitNoToSearch.Value & "'"
End Sub
Watch the output from Debug.Print in the Immediate window as you make changes to the context of the text box. (Ctrl+g will open the Immediate window.)
One final point is that just Me.txtUnitNoToSearch gets you its default property which is .Value. Keep that in mind as you work through the rest of your code.
