Validation Before Focus Enters Subform

Aug 25, 2004

When I click on my subform after entering some data in the primary form, I get this error message:

"The Microsoft Jet database engine can't find a record in the table <name> with key matching field(s) <name>. (Error 3101)"

This is because I have not filled in a ItemCode, a combobox, on the parent form and ItemCode is part of a one-to-many relationship that involves automatic filling in of other fields such as ItemDesc, UnitPrice, etc. How do I code the validation that handles such an error?

Thanks in advance,
Swee

Set Focus To A Sub-sub-subform

Jan 2, 2007

I have 4 nested forms:
DataEntryMaster
DataEntryMainSub (subform on DataEntryMaster)
DataEntrySub2 (subform on DataEntryMainSub)
DataEntrySub3(subform on DataEntrySub2)

In the AfterUpdate even of DataEntrySub2, I have code that checks to make sure the field on DataEntrySub3 (it has only one field) has been filled in. If not, I want to set the focus to DataEntrySub3.

The code in the DataEntrySub2 afterupdate event:
if isnull(me!dataentrysub3.productbarcode then
msgbox "You must enter a product barcode!"
forms!dataentrymaster!dataentrymainsubform!setfocu s
forms!dataentrymaster!dataentrymainsubform!dataent rysub2.setfocus
forms!dataentrymaster!dataentrymainsubform!dataent rysub2!dataentrysub3.setfocus
end if

I've used this most-wordy syntax because I couldn't get the shorter syntax (eg, me.dataentrysub3.setfocus) to work at all. However, this STILL doesn't work.

What's really puzzling is that if I run those exact same 3 setfocus statements from the immediate pane, they work fine. But in the afterupdate event, my focus always ends up on a control in dataentrysub2.

Any ideas???

Subform Won't Surrender Focus

Mar 9, 2005

Well, the title says it all really. After I click into the subform and type something in a text box, the focus will not return to the parent form, via mouse or tab. I can't even switch the form back into design view, it appears to be totally locked. Has anyone run into this before?

Set Focus To Subform But Do Not Activate

Sep 28, 2006

i won't go into details except i am doing databases for cemeteries - very complicated
example
i have come across two people who have the same name, date of death, buried in the same grave on the same day but are not related and must have seperate records!!
my main table has 6 primary keys. [even then i have 2 duplicates who are not related]
anyway one of the problems is this
i have a main form with 2 subforms. the main form is unbounded. i need to copy information from 1 of 4 queries run by the main form [QBF] to one of the subforms. i don't know which query untill i view the data.
when i know which one, i press a command button which copies the information to one of the subforms. when i repeat the actions above instead on the new query data going into a new record on the subform it overwrites the existing data instead of pasting it into a new record.
i have tried setfocus command - this works only if i click on the subform and activate it [this defeats the object of the command as i might just as well click in a new record box on the subform].
in essence i do not need to activate this subform at all. i just need to check if a record exists and if it does goto a new record [again this works only if i physically click on the form]
any ideas how i can force the cursor to goto a new record without physically clicking on the subform??

thanks

Forms :: Set Focus On Subform Control?

Mar 7, 2014

I have a form with a subform on it. The subform has subforms. I need to set the focus on a control on one of the subforms. Here is what I am using.

START OF CODE
Forms!frmMain!frmMainSub.Form.frmContactLog.SetFoc us
Forms!frmMain!frmMainSub.Form.frmContactLog.Contac tMethod.SetFocus
END OF CODE

I use Code 1 to get to the third level. Code 1 works.

Code 1
Forms!frmMain!frmMainSub.Form.frmContactLog.SetFoc us

When I add the second line, Code 2, it doesn't work. I get the message "Run-time error 438: Object doesn't support this property or method."

Code 2
Forms!frmMain!frmMainSub.Form.frmContactLog.Contac tMethod.SetFocus

Forms :: Set Focus To Last Line Of Subform

Jan 21, 2015

I have a single main form with a datasheet subform. When I scroll through the records shon in the main form, each has a different set of child records shown in the subform.

I want the focus to be on the last record of the subform each time.

On the main form, I have a button and this code

Code:
Private Sub cmdLast_Click()
Me.frmRevisionsSub.Requery
Me.frmRevisionsSub.SetFocus
Me.frmRevisionsSub.Form.txtRevTag.SetFocus
DoCmd.GoToRecord , , acLast
End Sub

which works perfectly, when I click the button.

If I call this code from main form's OnCurrent, focus remains on the first line of the subform instead of going to the the last. I have an inkling that it has to do with when the requery of the subform takes place, when I scroll through the records on the main form.

Forms :: Subform - Set Focus To Other Record

Jan 2, 2014

I have a form with a subform which is sized to show several records at the same time. If Record A has the focus, and I click anywhere in Record B, then Record B gets the focus, as expected. ... Except if I click on an Image field in Record B, when the focus stays on Record A.

How I can force it to set the focus to the other record ? I don't think this can be done with Events handlers, as they need to have the focus set first.

Multiple Picture Change Subform Focus

Apr 22, 2015

Is it possible for an image control to change to a different picture on a form when focus changes to a different record on a subform? I am developing a simple database to record my ever growing collection of TV shows. The form that I use to view my TV show records has an image control on it, I previously had a single image for the entire series (box art for first season). I now want that image control to change to a different picture when the focus changes to a different record on the subform. i.e. when the focus changes from the first season on the subform to the second season; the picture on the main form changes with it.

Forms :: How To Lose Focus From A Subform When Selecting Record

Dec 17, 2014

I have a form, with a subform,

When a user selects a record from the subform i use this to view the record in the main form

Private Sub Txt_Support_Name_Click()
DoCmd.ApplyFilter , "ID =" & Me.ID
End Sub

However when i select the record from the subform, it populates the form as required, however then the top record of the subform is highlighted.

Any way to either - highlight nothing, or highlight the selected row?

Forms :: Subform Takes Focus From Top Of Main Form?

Jun 29, 2014

I have a form that I created that has a tab control. When the form loads, it automatically sets the focus to a field in the subform. This wouldn't be a problem, except when it does it hides the tabs at the top of the form so I have to go and scroll back up every time I click a tab so that I can see the tabs. Is there a way to adjust this? I have tried hiding a field and setting the focus to it and that didn't work. I also tried setting the focus to the actual tab, but that also did not work.

Button Press Enters A (calculated) Figure On Form?

Jul 5, 2005

I'm sure this is really simple... apologies, but a search hasn't thrown up any clues.

I have a table with Invoice Value, and Commission Value in it. On the associated form I enter the Invoice Value, and also the Commisison value [which 99% of the time is set at 20%.

I am trying to make a button which, when pressed, enters the calculated commission in the form field (and underlying table) - I realise this could be in the 'On Click' property on the form, but in VBA I am after something like.

Private Sub btnCommCalc_Click()
tblSales.Commission = tblSales.Invoice * 0.2
End Sub

Could someone help me with the syntax? (I can then move on to using a variable, rather than hard-wiring the 20% ;-)

Many thanks

Subform Control Validation

Nov 4, 2014

I have a form that incorporates 2 subforms. I have all but 1 thing working as intended. I have setup a button to submit the entries (and handle a few other control functions) but I need to validate a single control within the first of the 2 subforms. This should be simple but it seems I am missing something. I just need to check for null or blank and if true open a message box to explain that it is a required field and to then exit the sub without any further execution. My problem is that no matter how I type the code I cannot get it to recognize the control (which is a combo box). Even identifying the from the control is on does not seem to work.

Forms :: Adding Value Of Combobox To Hidden Column When User Enters A New Record

Aug 14, 2013

I'm very new to access so I'm not sure about the correct way to go about this. I have a table with a 'category' column, a form which hides the category column, and a combobox to filter the category, let's say R, C, and F.

What I want accomplish is to have the value of the comobox applied to the hidden 'category' column when a user enters a new record into the form.

Is there I way I can get an instance to the record as it's being entered and modify the data using VB? Or would I have to write a sort of pop() function and have it run afterInsert and then modify it that way? Can I even alter the table using VB like this?

How "hide" A Subform That Is In Focus

May 6, 2005

I have a mainform (f1) and a subform (f2). The subform normally is not visible ([Fomrs]![f1]![f2].visible = Fasle). When I click on a command button on the main form, the subform wiill show up on the main form ([Fomrs]![f1]![f2].visible = True). There is another command button on the subform. When I click on the button, it opens up a third form (f3). The relationship between f1 and f2 is master-child, and the relationship between f2 and f3 is also master-child.

After I open the third form, I want to close (hide) the subform (f2), but I got an error saying that I can not "hide an object that is in focus".

Do you know any trick to do that? Thanks a lot.

Forms :: Prevent Duplicate Values With Alert After User Enters Duplicate Value

Dec 30, 2013

We are working on an Access (2007) database that is on a SharePoint Site (2007).

Currently the form is operational, but there is one last thing that would be nice to have.

The table is "Updated Headcount" which contains "EMP_ID" which are unique numbers stored as text.

In the event a new employee is entered in the system by another user on this site we would like to prevent any duplicate "EMPID"s from being entered and saved on the SharePoint, we would also like to alert the user and prevent the data from being saved.

All data is currently bound, so once the user makes a change it is made, no submit button is required.

We are running into some difficulties in doing a dlookup from the value entered and comparing to a column in the table.

TABLE - UPDATED HEADCOUNT
COLUMN in UPDATED HEADCOUNT - EMPID
FORM CELL user will input an EMPID - newEMPID
FORM CELL used for a dlookup to compare what user has entered to what is already in the table - duplicateEMPID

So below is what we are trying to do, we are sure there are a few commands missing....

=IIF(newEMPID=dlookup([UPDATED HEADCOUNT]![EMPID]), newEMPID, "Error, EMPID already exists")

Set Focus

Jan 9, 2006

I am having trouble getting the cursor to change focus after updating a field in my tab control subforms. I have a main form with a tab control and 4 related subforms for each record in the main form.

I have a calendar that pops up with the On Click of my Date field. When the date is selected, it enters it into the field and the calendar closes. For some reason though the user cannot simply go to the next record with the mouse and has to tab to or select another field in the same record first and then click on the Date field in the next record.

I have tried SetFocus to "Hours" (the next field after "Date")and "NextRecord" on every Event I can think of but it does nothing, it just stays on the changed field and the only way to get out of it is to go to another field. I've tried saving, requery, etc. I've also tried the options shown in the forum with no luck and using different events associated with the Calendar form - On Close, Lost Focus, etc.

Any suggestions? Thanks

Could Not Set Focus

Hi

I have a problem with setting focus to a text box. There is a listview on the form. Double clicking on a row will search the database for that record using SNo field and then display the contents on the respective control. When I click on a row the first time, it works.
