this is my first question here and english isnt my language but I'll try to explain at my best.
Im using MS Access 2007.
The form is a "continue form" with a header section where you find an "apply filter" button and a field named "cmpCercaCognome" (italian language for "find surname" plus "cmp" in italian language as field).
This is a cut out of the feature where I am having problems.
The function is fine if the search filter that is set in the field produces at least one result.
The function fails if there are no results.
Private Sub cmpCercaCognome_Change()
If (ActiveControl.Name = "cmpCercaCognome") Then
LunghStr = Len(Me.cmpCercaCognome.Text)
else
LunghStr = Len(Me.cmpCercaCognome)
End if
'Something else but I dont reach it
end sub
The error appear when I'm clicking in the field "cmpCercaCognome" and then Im typing a key there to change the value to use for a filter that I'll apply with a button.
The check "activecontrol" is true still the Len function give error "2185 - Cant read control... without an active status..). How? I just check that have active status! And Im typing just there...
I tryed to modify the IF check so:
"If (ActiveControl.Name = "cmpCercaCognome") And (Me.RecordsetClone.RecordCount > 0) Then"
So I can check just when the count of the record is more than 0.
The problem that so I check the .value of the field that dont contain the last pressed key.
So isnt usefull for me
Is there any way to avoid the problem by keeping control of the temporary value of the field? Or is there a way to make the "temporary value" effective right away so as to avoid checking the .text property?
Thanks for any help you can get on this.

I am trying to get an understanding of what the syntax would be to access a specific field within a query that makes up a subform within another form.
Form > SubForm/Query > Field
The field I am trying to get access to a field called Berthed that operates as a Boolean field. Either the vessel is present or it is absent.
This is what I was trying and it does not work.
Me.Boat_Move_Prior_Week.SourceObject.berthed
In this case here is the breakdown
Me = current form
Boat_Move_Prior_Week = query
Berthed = field I am trying to access through the VBA
My final goal will be to create an If statement, that upon requery of the Form, will look at the Berthed field, and if the field is checked (vessel is present) do nothing, but if the field is unchecked (vessel is not present) then remove the vessel from the query.
To reach the field (on the subform) bound to the field berthed, this is the syntax (assuming the textbox on the subform also is named berthed):
IsBerthed = Me!NameOfSubformControl.Form!berthed.Value
Here an amazing guide to know how to deal with controls in main form and subforms:
Link
Aside from my syntax issues I should have been using False for the value. Thanks to the two posters above for getting me in the right direction.
If Me.Boat_Move_Prior_Week.Form!BERTHED.value = False Then
Me.Boat_Move_Prior_Week.SourceObject = ""
End If
I'm wanting a button to perform multiple actions. when clicked it should:
add 1 to dial attempts field
change the "leagGenOutcome" to "no answer"
the problem is that the "leadGenOutcome" is a dropdown field taking it's options from another table.
I used this VBA code which works for a field with no drop down, but doesn't work on the drop down field.
Private Sub AddDialAttBTN_Click()
DialAttempts = DialAttempts + 1
LeadGenOutcome = "no answer"
End Sub
I know I must be missing something simple to get this to work. any help is much appreciated.
EDIT
by "doesn't work" the DialAttempts counter ticks up as it should but a "run time error" displays stating "the value you entered isnt valid for this field"
LimitToList property is Yes
"no answer" is a listed item
the field that LeadGenOutcome is bound to is called LeadGenOutcome01 in a form called LeadGenOutcomes.
currently it's a test database which I am using to learn how best to arrange and format.
changed "no answer" to "2" which is the ID for that response in the linked form. I had thought that it would display as "2" and not the associated text. this is not the case. thank you June7 for the assist.
I have some very (very) basic MS Access knowledge. I'm trying to expand a bit into either VBA or macros as I'd like to put in some conditional visibility for my form. Basically, I have a checkbox. If it's checked, I want three or four more fields to pop up. Someone was able to point me to a basic VBA formula of if (this checkbox) = true then, (fieldx).visible = true, else, (fieldx).visibility = false, end if.
But I'm so new to this that I need more help and explanation. I tried putting it in but couldn't get it to work (no error message, just nothing changed at all).
Specific questions:
-Does this formula seem right?
-If I want multiple fields to be visible, can I combine them into one formula or should I create a new "if" statement for all?
-Where do I enter this code? I'm running the Office 365 version. For all I know, I'm not even putting it in the right place.
-How do I determine the field names to replace the (this checkbox) and (fieldx) in the formula? I tried entering the name I title the fields as, but with the spaces in the name I got an error message, and without the spaces nothing happened. Is there a specific naming convention to turn the field names into formula-appropriate titles? Is the name listed somewhere?
-Once I get the formula entered, is there something I have to do to get it to run/take effect? I tried saving, closing and reopening with no changes.
-Is this the best way to go about this?
If there's anything else you think I should know, I would love to hear it - but please keep in mind I'm very new to this so if you could keep it at "dummy" or ELI5 levels of explanation, I'd appreciate it!
after creating a form with 4 textboxes and a checkbox put the form in design mode (lower right corner has design mode selected, select a textbox and hit property sheet on the ribbon (or f4).
On the property sheet note the visible property. set the visible property to false. Now the textbox will be invisible when the form starts.
Tip you can select all the textboxes at the same time and set their properties all at once.
Every control on the form and even the various parts of the form have properties you can set and play with. For instance you can give any name you want to any control. On the property sheet go to the other tab and set the name property.
Tip: choose a name you you will remember without having to look it up and describes the controls function.
Next select the checkbox (not the checkbox's label). On the property sheet go to the event tab and select the on click event. hit the ellipsis and choose code builder. Access is Event Driven. We want the textboxes to appear when the checkbox is selected so we put that code in the checkbox click event.
after choosing code builder we get the code window where we can browse among all the events for all our forms. for now all you should see is something like:
Private Sub mycheckbox_Click()
End Sub
So insert some code to handle the checkboxes like:
Private Sub mycheckbox_Click()
If mycheckbox = True Then
txtbox1.Visible = True
txtbox2.Visible = True
txtbox3.Visible = True
txtbox4.Visible = True
Else
txtbox1.Visible = False
txtbox2.Visible = False
txtbox3.Visible = False
txtbox4.Visible = False
End If
End Sub
now when the checkbox is not checked no textboxes are visible.
but when the checkbox is checked they appear
I am relatively new to Access and any SQL and VBA I have picked up is self-taught, so I would really appreciate answers that are not too heavily laden with technical terms...that said, I am having an issue with allowing comboboxes to be left blank on a form if the user chooses not to input data. Also, I am using Access 2016.
Initially the problem I ran into was that if a combobox was entirely skipped and left blank, or if the user selects the combobox and then tries to move on without making a selection from the list, they got the error "You tried to assign the Null value to a variable that is not a Variant data type," and were unable to move on to any other fields on the form or to save the record being entered.
I found this article that details a possible solution, but I can't seem to get it to work. I made an unbound combobox, set the Row Source to:
SELECT EmailID, PersonalEmail FROM EmailT UNION SELECT "<N/A>","<N/A>" FROM EmailT
ORDER BY PersonalEmail;
where PersonalEmail is a field of type short text and the EmailID is an autonumber. I also followed the article's steps for formatting the combobox (column width, etc.) and set it to Limit to List = Yes.
Here is my exact code:
Private Sub Combo62_AfterUpdate()
If Combo62 = "<N/A>" Then
EmailID = Null
Else
EmailID = Combo62
End If
End Sub
Private Sub Form_Current()
If IsNull(EmailID) Then
Combo62 = "<N/A>"
Else
Combo62 = EmailID
End If
End Sub
< N/A> now shows up on my list, but if it is selected I get the error: "The value you entered isn't valid for this field. For example, you may have entered text in a numeric field or a number that is larger than the FieldSize setting permits."
Access's debugger highlights the line:
EmailID = Null
but I am not sure what steps I should take now to try and fix this.
I am completely open to other methods of allowing the combobox to be left blank if someone knows of a better way to do this also. For all I know, I am missing something really obvious! Thanks in advance for any insight!
EDIT: Thanks for your help guys, I never did figure out what exactly the problem was, but I got some advice from another forum to rethink my database design so this ended up being a null issue--it's all totally different now!
If the recordsource for your form contains a query with one-to-many relationships this error may come up. Try to use only the base table as the recordsource for the form. Use subforms if you need to display related data. The rest of the code may then be unnecessary.
Hello kind helpful people,
I am having a major problem in Qlikview. I am just trying to create a button that can increment a variable by +1 each time it is clicked. I thought i could simply write an expression on a button click event but Qlikview is so different. I think it overcomplicates this matter by trying to be too simple.
The only thing i can do is 'Set a variable' to a specific value in the button properties.
Does anyone know how to do this?
Many thanks
Eddy
You can do this like you originally tried with an expression in the button action... the key is to make sure you put the = in there so vCount (or whatever your variable is called) gets evaluated first.
I am unable to add a comment, but I wanted to make sure you knew that macros won't work on server, so if you are doing it just for you it should be fine, but if you have it run on a server it could cause problems.
No that's the thing, as i mentioned in my original post all SET VARIABLE does is set a variable to a specific value that you have to specify but you cannot (as far as I know) set an expression that will increment the variable continiously by +1.
Anyway, I figured it out - and for anyone else whose stuck on the same issue:
I found a long winded way of doing it, although it works well.
1) Create your variable in Qlikview, mine is called 'vIncrement'
2) Set up a macro by going into button 'properties' > 'Add' > action type = 'External' > 'Run Macro'
3) Then name your macro and click on 'Edit Module'
4) Paste the following bit of vbScript:
Sub Increment
TheVal = ActiveDocument.Variables("vIncrement").getcontent.string
TheVal = TheVal + 1
ActiveDocument.Variables("vIncrement").SetContent TheVal, True
End sub
5) Click OK and close
This should do the trick.
I actually figured this out in about 20 minutes and I'm a total Qlikview amatuer whose never had any formal training in it lol, but StackOverflow.com won't let me paste my own answer for atleast 10 hours because I'm new here - I cannot understand why?
Never knew about vbscripting Qlikview Macro's until 10 minutes before - not bad eh for an amatuer?
I have to admit there must be a simpler method than this...but atleast this method works.
Cheers
