LibreOffice Base Basic Get form field value on load - forms

This works to get the value of a field at an event (say a button click):
Sub runatevent(Event as Object)
dim form as Object
dim cntrl
form = Event.Source.Model.Parent
cntrl = form.getByName("txtpath").currentvalue
print(cntrl)
End Sub
However when I try to fire this on the Form's "After Record Change" event, I get an error: "property or method not found: Model"
How do I get the value of "txtpath" on the "After Record Change" Form event?

To figure this out, I used XrayTool on the Event object. This is what worked:
form = Event.Source
As in my answer to your other question, I suggest reading the value from the result set:
nameCol = form.findColumn("PATH")
print(form.getString(nameCol))
The idea is that the form is based on a result set, so you can just read from the result set rather than getting a control from the form and then checking the value of the control. Just a little more elegant in my opinion.

LibreOffice Basic get Elements from form

I'm trying to get value from textfield on the form.
sub Test(oEv)
oForm = oEv.Source.Model.Parent
textBox = oForm.getByName("Description")
MsgBox textBox.Text
end sub
There is an Exception: "Type: com.sun.star.container.NoSuchElementException" on the line "textBox = oForm.getByName". I have a text field with the name "Description" on the same form, where is the button I press to run this macro. What is wrong here?
Check that the name is the same case, not description.
Also, use the Form Navigator to determine whether the control is under the form in the hierarchy.
Have you tried using an introspection tool such as MRI or XrayTool to view the properties of oForm? With the tool, expand the form to see if it contains the Description control.
Often in Base, it is better to deal with the form as a recordset rather than reading the controls. Here is some sample code:
Sub ButtonClickHandler(oEvent as Object)
'com.sun.star.comp.forms.ODatabaseForm
oForm = oEvent.Source.Model.Parent
lDescriptionCol = oForm.findColumn("DESCRIPTION") ' from underlying query or table
Print(oForm.getString(lDescriptionCol))
BasicLibraries.LoadLibrary("XrayTool")
xray(oForm)
End Sub

MS Access: Enter a specific text in a form using command button from another form

I would like to ask for your help on the following issue in MS Access.
I had created a form "CustomerListF", filled with command buttons for each client. For each button, I had created the following code:
Private Sub cmd_outlets_ABC_Click()
DoCmd.OpenForm "OrderFormF"
Forms!OrderFormF!Outlets = "ABC"
End Sub
The button would then open another form "OrderFormF" and enter "ABC" in the textbox named "Outlets". However, I realized the second line of code (Forms!OrderFormF!Outlets = "ABC") would always create a phantom record in my subform, which is located in "OrderFormF", and this record would travel to other clients' forms. This phantom record is usually created when the commandbutton is clicked twice (double clicks or subsequent clicks). It is a headache when the record starts to shift around.
enter image description here
I would like to seek your advice for vba code to edit the second line of code.
Thank you.
This approach for filling the field in opened form is not good. OrderFormF initialization and second line of your code with assigning value to the field may be executed in different sequence, they are not synchronized.
In order to avoid this, you should pass the argument to OrderFormF by another way. I would recommend to use OpenArgs parameter:
DoCmd.OpenForm "OrderFormF",,,,,,"ABC"
And then in Load event of OrderFormF assign the value to textbox:
Me.Outlets = Me.OpenArgs
In this case the "ABC" value will be assigned to first row in the form or to new record, if form is empty. Before assigning you can select the row if you need to assign value not to the first row. Also this way will protect you against double click on button, Load event executed only once during first form opening

ACCESS: Ticking checkbox on form if a value beginning with "(REF)" is selected from combobox

I am trying to tick a check box on a form when I select one of many combobox values that begins with (REF) - this is code that stands for Referral closure.
this is what I've done..it's not working
Private Sub ReasonForInappriopriateReferral_AfterUpdate()
If Me.RsnForInappropriateRef.Value Like "(REF)*" Then
Me.Check66 = True
End If
End Sub
Please help, I was previously trying to conditional format a label to a different colour if the closure reason was a Referral closure, but couldn't do that either and think it could be down to the IF Like command.
I added two controls exactly as you indicated. I populated my combo by setting the Row Source Type to a Value List, and the Row Source to "Blah Blah";"(REF) - Jackson";"Two Times";"(REF) - Tyson"
I put this in the Click event of a button:
If Me.RsnForInappropriateRef.Value Like "(REF)*" Then
Me.Check66 = True
Else
Me.Check66 = False
End If
it behaved exactly as expected. I then moved it to the AfterUpdate event of the combobox, and again it worked flawlessly. The only thing I can see is that in your example, the combobox does not have the same name as your sub (ReasonForInappriopriateReferral vs RsnForInappropriateRef). Are you sure your names are right?

refresh vb6 form in background without losing user entered data

I'm working with some old VB6 code and have a scenario I'm trying to correct. I have a form that allows you to enter a person ID (use renters this in a textbox at the top) and click "show" it lists the appointment in the textbox on the same form. There is also a button that loads a new form that allows the user to edit the displayed data and save the change.
E.g. Change persons age from 65 to 64. I make this change, and save it. The save is successful and I unload the form to return to Form1. However, I must click "show" again to refresh the displayed data in the textbox to ensure the change is visible. I cannot figure out how to refresh this form, so the user doesn't have to click "show" to repopulate the textbox with the new value. Can anyone assist? I can't just create a new instance of Form1, because if I did that the person ID field would be blank.
Thanks!
Short version: How do I refresh a form to get latest data while still obtaining the relevant person ID.
There's not enough information here to answer your question. The general pattern you'd use in this situation is as follows:
SearchForm launches ViewForm.
ViewForm launches EditForm. When ViewForm constructs its instance of EditForm, it passes Me to EditForm (perhaps by setting EditForm.Parent).
When EditForm's Save button click event fires, it calls Parent.ReloadData (where Parent is the ViewForm that launched the EditForm).
Here is the approach that should work. In the editor have a public property that returns whether the form was cancelled or not. (.Cancelled). You'll have an object that carries attributes of the person that you are trying to change the age of. Then it's pretty simple. Code in the main form:
dim oPerson as clsPerson
dim oFrm as frmAgeEditor
set oPerson = GetCurrentPerson()
set oFrm = new frmAgeEditor
with oFrm
set .Person = oPerson
.Show vbModal
if not .Cancelled then
' Update Main form with the contents of oPerson
end if
end with
You can just call in "Show" function right after updating.
Call Me.frmParent.Refresh
I used this to refresh the screen without losing data.
I had to dig through a lot of old code to figure it out. This section had been written a long time ago, and worked well.
Public Sub Refresh()
Call cmdDetails_Click
If tvwScreeningSchedule.Nodes.Count > 0 Then
tvwScreeningSchedule.SelectedItem = tvwScreeningSchedule.Nodes(1)
Call tvwScreeningSchedule_Click
End If
End Sub
It's quite a specific function, and "cmdDetails_Click" contains alot of custom validation, but it's not too dis-similar to AngryHackers answer.

How do you edit records from a VBA form that you want to interactively select?

I have a set of ComboBox's in an MS Access 2003 DB that are all bound to fields in a single table. However, the data that they allow you to select doesn't come from that table and instead comes from various other tables. This works fine for the record creation story but now I want to be able to edit the record retroactively. The problem is that I can't figure out how to refill the form elements without writing a bunch of custom code.
My initial inclination is to provide a combo box that limits your choices to record IDs and then do a custom query and use that to set the selected values in all of different form elements. However, I feel like I should be able to do something as simple as DoCmd.GoToRecord , , , ID and the form should repopulate just fine. I'm not opposed to doing the busy work but I'm sure I'm just missing something in my relatively puny knowledge of VBA and Access.
Just to add to the mix, I would offer two approaches, one recommended, the other not.
Approach 1: If you've bound your form to the whole data table (this is the non-recommended approach), you can use the combo box wizard to navigate to the requested record, but I wouldn't recommend it in recent versions of Access:
a. it doesn't allow you to properly name the combo box before it creates code.
b. the code is just WRONG.
Here's the code I just produced in my test database:
Dim rs As Object
Set rs = Me.Recordset.Clone
rs.FindFirst "[InventoryID] = " & Str(Nz(Me![Combo2], 0))
If Not rs.EOF Then Me.Bookmark = rs.Bookmark
This is wrong in so many ways it's just remarkable. This is what the code should be:
With Me.RecordsetClone
.FindFirst "[ID]=" & Me!cmbMyComboBox
If Not .NoMatch Then
If Me.Dirty Then Me.Dirty = False
Me.Bookmark = .Bookmark
Else
MsgBox "Not Found!"
End If
End With
There is no need to clone the form's recordset when the RecordsetClone already exists.
There is no reason to use an object variable when you can just directly use the pre-existing object.
There needs to be a check for a dirty record before departing the record because if you don't force the save, errors in the save process can lead to lost data.
But the better approach is this:
Approach 2: Use the combo box to change the form's underlying recordsource.
The AfterUpdate event of your combo box would look something like this:
If Not IsNull(Me!cmbMyComboBox) Then
Me.Recordsource = Me.Recordsource & " WHERE [ID]=" & Me!cmbMyComboBox
End If
Now, this only works the first time, as on the second resetting of the Recordsource, you end up with two WHERE clauses, which is not good. There are two approaches:
a. assuming that the form opens without a WHERE clause, store the opening recordsource value in a module-level variable in the form's OnLoad event:
Private Sub Form_Load()
strRecordsource = Left(Me.Recordsource,Len(Me.Recordsource)-1)
End Sub
And at the module level, define strRecordsource accordingly:
Dim strRecordsource As String
Then in the combo box's AfterUpdate event, you have this instead:
Me.Recordsource = strRecordsource & " WHERE [ID]=" & Me!cmbMyComboBox
Now, if your form opens with a WHERE clause already defined, it gets more complicated, but I'll not go into that and leave it as an exercise to the reader what the best approach might be.
I presume that you've already set up the row sources for each combo box. So long as you haven't limited the combo box to that list; it should display what you have stored in that column.
However, if your Combo Box changes its list for each row you can do something like this in the record's OnCurrent event or the field's GotFocus event:
Me.combo_box_name.Requery
After re-reading your question, I think I see what you are trying to achieve. You're on the right track with GotoRecord, although I would probably use OpenForm in this case, because it has a WhereCondition property that allows you to use SQL to specify exactly what record to open. It sounds like you want to implement a "jump to record" type functionality in your form, where the user selects a record ID from a list and the form changes to display the selected record.
One possibility is to switch to the new record each time the user selects an item in the ComboBox. You can handle this in the ComboBox's Click event.
I'll use a simple example: suppose you have a Students table, and a StudentForm for viewing/editing records in the Students table. The StudentForm has a ComboBox cboStudentID that is bound to the Students.ID column via it's RowSource property. When you select a student ID in the ComboBox, the StudentsForm will switch to display the corresponding student record.
In the Click event handler for the ComboBox, you can code this "jump to record" functionality with something like the following:
Private Sub cboStudentID_Click()
Dim recordID As Long
'The ItemData property will return the value of the bound'
'column at the specified index.'
recordID = cboStudentID.ItemData(cboStudentID.ListIndex)
'Jump to the record. This assumes we want to use the same form.'
'You can change the form name if you want to open a different form when'
'the user selects an ID from the ComboBox.'
DoCmd.OpenForm "StudentForm", WhereCondition:="Student.ID=" & recordID
End Sub
As David W. Fenton points out in the comments, you can shorten the following line:
recordID = cboStudentID.ItemData(cboStudentID.ListIndex)
to this:
recordID = Me!cboStudentID
or just:
recordID = cboStudentID
since the default value of the ComboBox in this case will be the value of the bound column at the current ListIndex. In this case, you could just remove recordID altogether and code the Click event as follows:
Private Sub cboStudentID_Click()
DoCmd.OpenForm "StudentForm", WhereCondition:="Student.ID=" & cboStudentID
End Sub
