Solved: If Structure

[tibby812]

Hi, im trying to write a condition in an Access report. I have a checkbox field in my report that shows me the person owes me money. Now i would like to write an If statement saying that

if the checkbox is checked then
the lable of the checkbox is visible.

Now i've tried

If chkBox.Value = True Then
lblChkBox.Visible = True
End If


Any Suggestions!! Thanx

I forgot to mention, the field in the table is a Yes/No field. It is already populated with data.

Sorry if I'm wrong, tibby. I'm not good with this stuff.

Try this syntax, changing the values, of course:


'checked = 0
'unchecked = -1
If (MyField = -1 Or IsNull(MyField)) Then
Me.MyLabel.Visible = False
Me.MyField.Visible = False

Else
Me.MyLabel.Visible = True
Me.MyField.Visible = True

End If

Hi tibby

Are you trying to hide the CheckBox? if so try:


If CheckBox1 = True Then

CheckBox1.Visible = True

End If

If CheckBox1 = False Then

CheckBox1.Visible = False

End If


If you just want to change the Caption try:


If CheckBox1 = True Then

CheckBox1.Caption = "Visible"

End If

If CheckBox1 = False Then

CheckBox1.Caption = "Hidden"

End If

Im not trying to change the caption or trying to hide it, i can do those things, but dreamboat is on the right track, i basically want to say if the field is yes, then display a lable. When i put

If chkBox.Value = True Then
lblChkBox.Visible = True
End If

it tells me that there is no value

The exact error is run-time 2427 , You enetered an expression that has no value

Thought this might help

I have a table called Main Table

i have 5 fields

Name = txt
ID = AutoNum
Over21 = Yes/No
HasComputer = Yes/No
HasCellPhone = Yes/No

Ok........now enter 5 people in the table and check the boxes.

Now Create a report thats bound to MAIN TABLE

In the detail, add all the fields.

Now field Over21 , HasComputer, HasCellPhone are check boxes. These check boxes have labels.

Now i have code saying

Private Sub Report_Open(Cancel As Integer)
chkOver21.Visible = False
chkHasComputer.Visible = False
chkHasCellPhone.Visible - False

Now this also hides the labels that are bound to these fields, but i want to say if the field chkOver21 is checked , display the corresponding label.

if chkOver21.Value = Yes Then
lblOver21.Visible = True
end if

Now you may ask why i don't try exactly what i wrote to you, but i did, and it gives me a "run-time error 2427, You enetered an expression that has no value"

[Anne Troy]

Did you try the syntax I gave?
What happens then?

PS: See the little VBA button just above the reply box.
Use it to make your VBA code look like code. Click it, and paste the code between the tag sets. :)

Drreamboat,

I tried the code that you gave me and it gives me the same error. 2427 Runtime Error

I placed this in the AfterUpdate event of the checkbox and it works fine (on Off 2003)


If cbox.Value = True Then
lblCbox.Visible = True
ElseIf cbox.Value = False Then
lblCbox.Visible = False
End If

[Zack Barresse]

couldn't you shorten that James to:


If cbox.Value = True Then
lblCbox.Visible = True
End If
lblCbox.Visible = False

???

[jamescol]

Hmm - I think in your example, even when the IF statement executes, the


lblCbox.Visible = False


line will execute every time. So lblCbox.Visible will always be set to False.

It's late, so maybe I'm just not reading it right.

[jamescol]

You could shorten it like

If cbox.Value = True Then
lblCbox.Visible = True
Else
lblCbox.Visible = False
End If

[Zack Barresse]

my line of thinking was, it's checkbox, right? I mean, we're looking at boolean values, so it's either True or False. You only need the one if statement and no Else.

But it's late for me too, so, I could be wrong.

edit: disregard, I'm WAY wrong - too tired. :eek:

Ok, I've scanned this thread a bit quickly so I may have missed something.

Putting code for this in the Report_Open Event isn't going to do a lot of good. You want to set the properties in the Detail_Format Event.

As all your values are Boolean, you can also shorten it something like this ..

chkOver21.Visible = chkOver21
chkHasComputer.Visible = chkHasComputer
chkHasCellPhone.Visible = chkHasCellPhone

lblOver21.Visible = chkOver21
lblHasComputer.Visible = chkHasComputer
lblHasCellPhone.Visible = chkHasCellPhone

[SJ McAbney]

You could shorten it like

If cbox.Value = True Then
lblCbox.Visible = True
Else
lblCbox.Visible = False
End If

Or:

Me.lblCbox.Visible = Me.Cbox

;)

To Tony Jollans, your advice inspired me and i wanted to thank you for your info.

This is what i did,


Private Sub Detail_Format(Cancel As Integer, FormatCount As Integer)

chkOver21.Visible = chkOver21

lblOver21.Visible = chkOver21.Visible

End Sub

One thing:

Try never to imply what you are referred to - always be explicit. Include the reference to the current report's Class (Me.) - it helps the speed of the database once compiled. It simply means that when running the database doesn't have to find where the chkOver21 and lblOver21 objects are. By including the explicit reference to the report's class, it knows immediately reference these objects on that report.

Private Sub Detail_Format(Cancel As Integer, FormatCount As Integer)

Me.chkOver21.Visible = Me.chkOver21

Me.lblOver21.Visible = Me.chkOver21.Visible

End Sub

[Anne Troy]

Hey, tib?
Is this resolved yet?
It appears to be...

[DarkSprout]

Instead of


If Me.cbox.Value = True Then

lblCbox.Visible = True
Else
lblCbox.Visible = False
End If




Try Some Simpler Code:

[lblCbox].Visible = [cbox]
