Visible And Null
Mar 30, 2006
Simple but confusing.
I have a form with several controls. NAME, DOB and AGE.
NAME and DOB have a source to a table while AGE is unbound.
I would like a code that when opening the form, will show the age only if the DOB contains data.
Basically something like this:
If IsNull (Me!DOB) Then
Me.AGE = Null
Else
If Not Is Null (Me!DOB) Then
Me!Age.forecolor = VBWhite 'this hides the data)
End If
End If
Any help what I am doing wrong?
Thanks.

I want my fields on the report to show up if there is data to show and to disappear if no data is avaliable. Also, will the fields format together or will they still stay apart? I need them closer together for the report.
Here we go.
In the report are months 1, 2 and 3 as well as the label box for each. I need the label box and the data(text box) to disappear when the data box is null. This is where I had started:
Private Sub GroupHeader1_Format(Cancel As Integer, FormatCount As Integer)
If Not IsNull(Me.Ctl1_Month) Then Me.Ctl1_Month.Visible = True
Else
Me.Ctl1_Month.Visible = False
End If
End Sub
But when I try and run the report I get this error:
Can't Execute Code in Design Mode.
Can someone help as to what I have done wrong or where I should place this type of format?
Many thanks.

I am building a report that has a header with several details followed by a detail section.
What I need to do is make the entire entry not visible on the report if one of the dates is null.
So it looks like this
last first title id memb # date a date b
1. smith , john fng 8521 2356224
5/12/2012 6/20/2013
10/2/2013 (is null)
2. neckbone, jim dude 2548 85858412
6/20/2013 5/5/2014
8/5/2013 2/31/2013
On the report i want the 1st entry (smith john) not to be visible due to the null (B) Date.... but i want it to be visible once the date is entered...

I have a combobox on my form called TypeOfBusiness, with fields including Corporation, Education, Industry, Non-Profit. In order to make a second combobox called IndustryClassification appear when Industry is selected from the TypeOfBusiness combobox, I have used the following code:
Code:
Private Sub Form_Current()
If Me.TypeOfBusiness = "Industry" Then
Me.IndustryClassification.Visible = True
Else
Me.IndustryClassification.Visible = False
[Code] .....
It works just fine. However, when a user selects both, say, Industry and Education, the IndustryClassification combobox will not appear. What code I can use to ensure the IndustryClassification box will appear regardless if another box is checked in addition to Industry? I am wondering if it has to do with the Column attribute.

I have a Main Form with a Sub-Form, the sub-form is base off a query. on the sub-form i have 8 controls, one of them is "Status' and "Process" and "Review" My Main Form have a Refresh command that refreshes the data in the sub-form.
What i am trying to do is make the "Process" Control only visible is "Status" is a certain status and "Review" visible if "Status" is something else. what i have done works correctly On Open. I run into and issue on the refresh command. I get Run-time error '2165' "You can't hide a control that has the focus"
Code:
If Forms!Main_Form.[Name subform]!Status = "Ready" Then
Forms!Main_Form.[Name subform]!Process.Visible = True
Forms!Main_Form.[Name subform]!Review.Visible = False
ElseIf Forms!Main_Form.[Name subform]!Status = "Reviewing" Then
Forms!Main_Form.[Name subform]!Review.Visible = True
Forms!Main_Form.[Name subform]!Process.Visible = False
End If
I have done similar with a main form and making sub-form visible or not based on a control on a main form and that has worked perfectly. I am not sure how the control is getting focus and cause the error.

I have a form with four subforms set up in a tabs on the form. In the subforms I have a copuple of command buttons which enable/make visible fields when they are clicked (see previous posts but for eg) - if a height and a weight are added in two separate boxes a calculation is done and then a command button pressed to make visible the (label) which shows the mass index the patient falls into. My problem is that the label is then retained so if I click out of the form and re-enter with a new patient then the height and weight boxes are clear but the label from the previous patient remains.
I tried to put the code
Private Sub Form_Load()
If PtWeight = Null And PtHeight = Null And Text60 = Null Then
Label106.Visible = False
Label101.Visible = False
Label177.Visible = False
Label122.Visible = False
Label123.Visible = False
End If
End Sub
in both the open and on load event of the main form (not the subform) but it doesn't help. Any ideas?
(When should code be put on the main form and when on the subform?)

I do not understand what is happening here. I have foll0wing line in a calculated query field:
m: Switch([EmpID]<5,1) ' run Query 18 in attached example, A2007/2010
this produces 1 for all EmpID<5 and Null for all other EmpID's. All as expected.
But if I do this:
m: Switch([EmpID]<5,1,[EmpID]>=5,Null) ' run Query 19 in attached example
then the entire column is set to Null

It might be an easy one but I just wasted the past hour deciphering through my code in order to solve the run-time error '94' that I'm getting when trying to execute the following code:
Code:
Private Sub cmdUpdateDates_Click()
'###################################
'This sub aims at combining the timesheet date and the start and end time into the fields [Start Time] and [End Time].
'###################################
Dim intCounter As Integer
intCounter = 0
Dim rs As ADODB.Recordset
[Code] ....

Hello all,
A bit of a weird one, I've got a query and the criteria for showing records is that one particular field is null. However the query is showing records with the values in the field chosen for the Is Null.
Not sure why this is happening, has anyone come across this problem before?
Thanks.

I think the title pretty much sums it up....
I have a query where data is first sorted by user input; first field's criteria: [fieldname], then by another field's criteria: Is Null.
I know there are records containing null values in the second field, as I have run a select query with the criteria: Like "*", to make sure they are null, and not zero-length-strings.
The query is refusing to return any results...
Any ideas?

This might sound simple to everyone, but it won't work for me. I have a text box on my form that holds the current date, there are also other text boxes that hold other information. Here's what I'm trying to do, if the other text boxes are empty then I want the date text box to be invisible. Here's the code I'm trying to use:
Code:If [EquipmentType1]=" " Then[DateSigned].visible = FalseEnd IfEnd Sub
By the way this is triggered from the Form Load event. Thanks for any help you can provide.

In my form, I have a combo box with one of three options (cash, check, reimbursement). If the user chooses check, I want a text box to become visible, so the user may input the check number.
I thought I could use another invisible text box to store the value of the combo box and then in the code put:
Private Sub Text64_AfterUpdate()
If Text64 = "Check" Then
Me.Check1.Visible = True
Else
Me.Check1.Visible = Refresh
End If
Me.Refresh
End Sub
Text64 is holding the value of the combo box
Check1 is the text box where I want the user to put the check number.
Please help. Thanks

Hello. In my table there is a checkbox column. This box is checked on a form which feeds the table. I run reports from queries which contain both checked results as well as unchecked results. Is it possible for on the report, for the text (the field name, not the checkbox) to only appear when the box is checked? I hope I'm explaining this properly. I want the checkbox title to only appear on the report when the box is checked, otherwise I don't want it visible.
Thanks for your help.

Hello,
I have a form with twa txtboxes named mytxt and txtresult.
The txtresult gets its data from a module (GetInterval).
I have written this statement:
If IsNull (Me.mytxt) then
Me.txtresult) = Null
I get an error as if that control cannot contain null values.
I have done the same with another sample, simply changing the record source of my txtresult to a field of my table and works?
can anyone see the problem?
I have also tried in with this code but still nothing:
If Len(Trim$(Me!USER & vbNullString)) = 0 Then
Thanks.

I have a form with a subform on it, if the user clicks a control on the subform I want to set the subforms visible property to = False.
I have tried Me!Subform.visible=False and Form!Subform.Visible=False but neither are working, I think i have to set focus back to the main form before I can set the visible property of the subform.
