I have a form (split form) and i want to prevent access from creating a new record when the user reaches the final field of form and hit the enter key. I already tried to change the Cycle property in the Other tab and didn't work
By split form i mean a form that has Split Form on Default View in the Format tab
On Access Form,
Form.AllowAdditions = False
Will forbide adding new record.
You can set this property in both the design view and at the running time.

I have a continuous form which displays a small amount of data from each record in my table ProjectT (i.e. project name, status) and a command button in the footer which I would like to open the selected record in its expanded single form (where all of the relevant info is displayed).
At first I set this button up using Access's wizard, but realized that Access opens a selected record by filtering the data on the form. The problem with this is that once the expanded form is opened, I want a user to be able to move to other records without having to select to unfilter the results. If I change the button on my continuous form to simply open the expanded single form, is there code I can run to make the form open to the selected record without putting a filter on?
Initially I thought to set the expanded form's (named ProjectF) default value to Forms!ProjectListF!ProjectID (where ProjectListF is the continuous form and ProjectID is the autonumber primary key for ProjectT), but this was not successful, I think because there is more than one ProjectID displayed on ProjectListF.
Another thing to consider is that I have another button on my Main Menu form which opens the ProjectF form in data entry mode to prevent the user inadvertently changing/deleting an existing record when they are trying to add a new one; I have no idea if this might be important when trying to find a solution to my issue.
I'm open to any suggestion--I have an okay handle on SQL, and have delved into a little VBA but am completely self taught. Any ideas? Thanks!
You can open the detailed form with this command:
DoCmd.OpenForm "ProjectF", , , "[ProjectID] = " & Me!ProjectID.Value & ""
I have an Access 2010 application that has a form with a text box and a command button on it. Clicking the command button places a default value in the text box.
Question: When a user clicks the command button I can either:
Run an SQL update to save the new text box value in the data source that it is bound to plus set the me.textbox1.value to its new value, or
Run the same SQL update to save the new text box value in the data source that it is bound to plus do a form.requery?
Which is better? Would changing the bound value in the data source initiate a current event and an automatic requery?
Thanks in advance.
If you want to save the entry immediately, I would write the value to the text box, and do
Me.Dirty = False
to save the record in the bound form.
I see no point in doing this via SQL.
Would changing the bound value in the data source initiate a current event and an automatic requery?
No, that would actually be the worst method. The form wouldn't know about the changed data source, and once the user would start editing, he would get the "Write Conflict" message.
Your 1. would have the same problem.
I have a database that was create in Access 2010. We recently updated our systems to Access 2013. In Access 2010 I have no errors accessing a form object with
Form_frmName.txtFieldName.Value
However, when using Access 2013 I get a runtime 2424 error stating that "The expression you entered has a field, control, or property name that Microsoft Access can't find. I am accessing from a module.
The module sets these fields visible using
With Form_frmName
.txtFieldName.Visible = True
End With
before attempting to access them.
Has there been any changes in the way form objects are accessed between 2010 and 2013? Is this an issue others have faced?
In Response to #WayneGDunn's questions below
QUOTE:
I need to know exactly what and how you are using this.
1. You have a bound textbox named 'txtFieldName' on a form. As #brad asked, is there a subform, and if so, is this field on the subform?
2. You said the code is in a module, but is the code in the form where the field is defined?
3. Please explain where/what form 'frmQAtab' is (you said your form name was 'frmName', so what is the other, how related?)
4. Is the code in an event? Can you share the entire subroutine?
5. Have you tried creating a dummy query and using the builder to reference the field?
RESPONSE:
1. I have a form (frmMain) with multiple tabbed pages. frmName is one of those tabs, containing the bound field txtFieldName.
2. The module is run from the form the field is in.
3. My apologies frmQAtab is frmName, I just neglected to make that generic in my copy-paste.
4. The event is a button click. The button click runs a sub from a module. That sub makes visible the fields, runs a query based on user input (two date fields), populates the bound fields with the returned record set, then attempts to access them for processing (another query is run to process a complete other set of fields). To post the entire subroutine would be a bit more than I would ask you to chew on. This is legacy code I'm trying to fix, and it's rather large.
5. I have not tried a dummy query. Access is not my field (I'm mainly a C#, scripting, guy.) Is there some suggestions in this area you could give?
One of the following references to your fields should work. I created a form (named 'frmMain'), then created a Tab Control with two tabs. On the first tab, I inserted another form (named 'frm3197'). I also created a text box on the tab control named 'txtFieldName' AND in form 'frm3197'. From a button click on 'frmMain', the following will reference each of those fields.
Private Sub cmdButton1_Click()
Forms![frmMain]![txtFieldName] = Now()
Forms![frmMain]![frm3197].Form![txtFieldName] = Now()
End Sub
I made a windows form which contains a listbox (named VenueList). The listbox is pulling it's values from a list provided by a binding source VenuesBindingSource which is pulling in a ID for the value and a name for the text.
There is a button which is causing a DialogBox to appear which is asking for values to store in the database for a NEW venue. Once the values are filled and insert the database, what's supposed to happen is that the dialog box closes and goes back to the original form which invoked it.
However, instead of updating the list. The list stays the same. But if you close the form and reopen it, you see that a new value was added.
TournamentSettings.VenuesTableAdapter.InsertVenueQuery(Trim(VenueNameTxt.Text), Trim(VenueAddress1Txt.Text), Trim(VenueAddress2Txt.Text), Trim(VenueCityTxt.Text), Trim(VenueProvinceTxt.Text), Trim(VenueZipTxt.Text), Trim(CountryBox.SelectedValue), Trim(VenuePhoneNo.Text), VenueType.SelectedText, VenueWebAddress)
TournamentSettings.VenuesTableAdapter.Fill(TournamentSettings.VenueNameList.Venues)
In the above code, InsertVenueQuery is the name of a query from the designer which is invoked to add the values onto the tableadapter VenuesTableAdapter which is used to fill the combo box on load. I also sent the Fill command to refill the table with the new value.
So the question is, should I go about doing this another way, rather than feeding the Table adapter and sending a fill command on to the datatable? Or is there something that I'm not doing here which I should to force that value into the list. I'm tempted to redo everything outside of the designer but that's a lot of code since I have to essentially run two commands (one to insert the data, and another to get the ##IDENTITY value since this is run on an access database.)
Okay. This one I had to think about for a moment.
Instead of me creating a block of done on the load event, I instead created a sub function called "FillVenueList".
I used the following block of code:
Public Sub FillVenueList()
' Adding values from database to a datatable.
' From there will add to the list box.
Dim VenueConnection As New OleDb.OleDbConnection(DBconnection)
VenueConnection.Open()
Dim VenueConnectionQuery As New OleDb.OleDbCommand("SELECT VenueID, VenueName FROM Venues", VenueConnection)
Dim VenueDataAdapter As New OleDb.OleDbDataAdapter(VenueConnectionQuery)
Dim VenueDataSet As New DataSet
VenueDataAdapter.Fill(VenueDataSet, "Venues")
TrnVenueLst.DataSource = VenueDataSet.Tables("Venues")
TrnVenueLst.DisplayMember = "VenueName"
TrnVenueLst.ValueMember = "VenueID"
VenueConnection.Close()
End Sub
From there I called THIS sub on both the form AND the Add Venue window and I can safely see that this works. SO THAT is how you get a new value onto the form, don't use it as a part of the Load Event but rather call it from the load event block, then call it when you want to add to the list.
I'm currently creating a WinForm in VB.NET bound to an access database.
Basically what i have are two forms: one is a search form used to search the database, and the other is a details form. You run a search on the searchForm and it returns a list of Primary Keys and a few other identifying values. You then double click on the entry you want to view, and it loads the details form.
The Details form has a collection of databound controls to display the data: mostly text boxes and checkboxs. The way i've set it up is i used the UI to build the form and then set the DataBindings Property of each control to "TblPropertiesBindingSource - " where value name is one of the values in the table (such as PropertyID or HasWoodFloor).
Then, when you double click an entry in the searchform, I handle the event by parsing the Primary Key (PropertyID) out of the selected row and then storing this to the details form:
Note: Detail is the details form that is opened to display the info
Private Sub propView_CellDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles propView.CellDoubleClick
Dim detail As frmPropertiesDetail = New frmPropertiesDetail
detail.id = propView.Rows(e.RowIndex).Cells(0).Value
detail.Show()
End Sub
Then, upon loading the details form, it set's the filter on the BindSource as such:
TblPropertiesBindingSource.Filter() = "PropertyID=" & id
This works great so far. All the controls on the details form will display the correct info. The problem is updating changes.
Scenario:
If i have the user load the details for say, property 10001, it will show a description in a textBox named descriptionBox which is identical to the value of the description value of for that entry in the database. I want the user to then be able to change the text of the text box (which they can currently do) and click the save button (saveBut) and have the form update all the values in the controls to the database.
Theorectically, it should do this as the controls are DataBound, thus i can avoid writing code that tells each entry in the database row to take the value of the aligned control.
I've tried calleding PropertiesTableAdapter.Update(PropertiesBindingSource.DataSource), but that doesnt seem to do it.
Ok, I was able to figure this out picking apart some code I pillaged from a friend.
Everything was ok, the problem was the updating
When I was saving the data, i was calling just:
Me.TblProptertiesTableAdapter.Update(Me.TblPropertiesBindingSource.DataSource)
The correct code, without changing anything else is:
Me.Validate()
Me.TblPropertiesBindingSource.EndEdit()
Me.TblPropertiesTableAdapter.Update(Me.RentalPropertiesDataSet.tblProperties)
Me.RentalPropertiesDataSet.AcceptChanges()
Where RentalPropertiesDataSet is the database where TblProperties comes from. Inorder for this to work, make sure TblPropertiesBindingSource.DataSource is RentalPropertiesDataSet.Properties This was autosetup for me by VS08 when it created the BindingSource.
Basically, I needed to tell teh BindingSource to stop allowing the fields to be edited. Then we save the changes to the database, and lastly we tell the DataBase to accept the changes.
