Modules & VBA :: Creating And Initializing Custom Class / Object
Jun 13, 2013
I've been playing around with creating my own class in VBA but I'm having problems calling its methods. My class is pretty basic, its called cDentist and the properties are just Name, Address, DOB etc and one method AddDentist. AddDentist will add the details to a sql server table.
So I create an instance of the class in a module called Dentist. At the very top of the code i put..
Code:
Option Compare Database
Global Dentist As cDentist
I have a method then in module Dentist, where I initialise the instance of class cDentist and i populate it's properities...
Code:
Sub RecordDentistDetails()
Set Dentist = New cDentist
Dentist.Name = Forms!frm_enterdetails!txtName
[Code].....
When I click 'Save' I get error, Method or data member not found. And '.AddDentist' is highlighted. I'm a little confused why it's not seeing AddDentist as a method of class cDentist.

I have wrote a database in access 2010 and the database works fine for me (I am the db admin with full control).I gave the database to a group in which most of them also have no issue with the file. They are able to use the database with no issues..One of those members gets an error message when completing the initial step in the database: (select a drop down item from a combo box)
Code:
The expression After Update you entered as the event propoerty setting produced the following error: Object or class does not support the set of events
Something I cant seem to understand is why is this happoening on 5 machines but not on the 6th, they all have the same PC set up so there should be no error on one particular machine.

I haven't created classes in a while, and I don't see what is the problem
I'm modifying a function to get fractions from double. It worked well, but it returned a string.
I need it to be in parts, so I created this class
Code:
Option Compare Database
Public Entier As Integer
Public nominateur As Integer
Public denominateur As Integer
Public Function getText()
getText = Entier & " " & nominateur & "/" & denominateur
End Function
I changed the function type and the assignation:
Code:
Function GetFraction(ByVal Num As Double) As nombreEnFraction
Set GetFraction = New nombreEnFraction
If Num = 0# Then
GetFraction = "None"
Else
Dim WholeNumber As Integer
Dim DecimalNumber As Double
[Code] ....
For some reasons, when I get to the end of the function, I get a 91 error, like if it was nothing
But when I use a spy, I see values in the object until the end.

This is the error I'm getting. A little obscure, I know, but this is happening in an executable Access application (2010 accde) when I click the close button on a form.
The code behind the form is checking a lot of stuff (data validation, etc.), but "Object or class does not support the set of events" is the error. Then the application continues as if nothing had happened.
The app was converted not long ago from XP ACC2003 to Win 7 ACC2007-2010.

I am writing a process for a hospital application in the UK
We have a concept of "Takes" which are periods to which patients coming into hospital are assigned to and thus the consultant (specialist) who looks after them.
They are fixed times between 0800-2000 (Day take) and 2000-0800 (+1) Night take.
I have written the following function to try and determine which take a patient should be assigned to based on the time now to power various queries to enable the end user to quickly see "today's day take" and "yesterday's take"
Testing it I seem to not be able to hit the right "Take times" in my output. I suspect it's a problem with the way I'm initiating my variables as Today 0800 and Today 2000
Code:
Function GetTakeStarttime()
Dim StartTime As Long
Dim EndTime As Long
Dim CurrentTime As Long
Dim YestStartTime As Long
[Code] .....

I'm working to put together a shortcut menu for a form that will be viewed as a datasheet. I'm trying to put together the vba to create the menu. I'd like a lot of the standard options i.e. sort a-z, filter toggle etc. I'd also like to add the menu option that is displayed in the default menu called "Text Filters". I've been unable to find the id code for that option, and since it, when chosen opens another menu, I'm not real sure how to code it. Here is what I have so far:
Sub CreateWIPShortcutMenu()
Dim cmbRightClick As Office.CommandBar
Dim cmbControl As Office.CommandBarControl
' Create the shortcut menu.
Set cmbRightClick = CommandBars.Add("cmdWIP", msoBarPopup, False, True)
[code]....

Hello all. I have deleted a Report but the underlying reference in the VBE editor in the CLASS OBJECTS list remains for the report and is giving me errors during run and compile.
Any idea how to delete the Class Object once the object has been deleted?
Any other suggestions?

I have Access 2007 database.
I and trying to link to Outlook 2007 using the "External Data/More/Outlook Folder option and keep getting the "Object Class does not Support the Set of Events" error message.
I can link to a DBF and Paradox file without any problems.
I am running Office 2007 Professional and Access 2007 and Windows 10.
I have also done the following:
1. Removed Office 365
2. Decompiled the Access VBA code and corrected any issues
3. Compacted/Repaired the database
I have attached a screen shot of the references that I have selected.
This is a new setup as I recently purchased a new PC and Windows environment. I still have the old PC running Windows XP with the same configuration and it also experiences exactly the same error message.

I have distributed my front end on the shared drive for users to copy to their desktops.
In one form I have a formula in the query that show's the word 'Gap' if any of the 15 questions on the form is equal to 'fail'. It runs on current when the user is in a record it shows the word 'Gap' at the top header part of the form.
When the user opens the form they get an error message pop up that says "The expression On Current you entered as the event property setting produced the following error: Object or class does not support the set of events."
Once they click 'ok' they are able to work in the form until they attempt to filter records by their name it pops up again.
I've tested on my end and no errors or issues come up.

Couple days ago our database was not opening, Access would open but show a blank workspace. Anyhow, we restored the database from Server and it worked on all 5 shared systems on company's network but this one computer. It is giving the error, "Object or class does not support the set of events."
I tried to copy new local folder but nothing. I checked the links and target folder it looks fine.
I tried to import the everything into new database but it said I don't have permission for that.
what's causing this issue and what can I do to fix it?

I finally got tired of having 100 macros managing my different custom shortcut menus, and decided to figure out how to generate the shortcut menus programatically (because lets be honest, Macros are the devil.)
I found a good tutorial here : [URL] .....
and was able to create some basic shortcut menus like the following:
Code:
Sub CreateCopyShortcutMenu()
Dim cmbshortcutmenu As Office.CommandBar
Set cmbshortcutmenu = CommandBars.Add("CopyShortcutMenu", _
msoBarPopup, False, False)
'ID 19 adds copy command
cmbshortcutmenu.Controls.Add Type:=msoControlButton, Id:=19
End Sub
Nice and simple, now I have a copy command. But the problem is that I also need some custom commands. Most (possibly all?) of these would be function calls.

I have a form that the Training Admin will use to select students to a new class.they select the Class Name from a ComboBox tied to TblClass.they select an Instructor from a ComboBox tied to TblInstructor and then, I am trying to to use some method to select students by identifying information (EmplID, LName, FNAme, MName, EMP# from TblEmployee) one at a time (from a combo box, or some other easy select method) that will pass the students information to a list, viewable and editable (remove a name) before it is committed to a TblCompletedTraining
I looked at a cascading combo-boxes, and that looks like a good method to selecting from the large number of employees in TblEmployee, but I am unsure how to store each selection on the form, and then allow the Training Admin the ability to delete members from the pool prior to committing. I am reluctant to use the multivalue field as a solution for a couple of reasons;
- It explicitly states to be used for relatively short lists only (no value limit given; so I assume 100 or less items)
- will probably need to convert this database sometime in the future.
I thought I had figured this out, by using a combo-box selection to generate a filter, but it leaves me with only one selection in the end..

I am trying to make a special kind of blob chart. It has to mimic the charts I have attached. I have a high number and a low number for everything that someone might want to put on the axes. The eventual goal is to have a form were the user selects what goes on each axis, and have a few other possible choices to limit how much is displayed. What I am making doesn't have to be as fancy, flexablity is more important. Can Access make this kind of graph or am I on my own, making shapes in VBA?

Hi.
Can anybody help?
I would like to create a custom theme for my INPUT page, however within Access 2003 I only have the option of about 20 predefined themes. I want to insert my companies' logo onto the INPUT PAGE.
What I would like is to save a template, like I have done in REPORTS, so that when I build a INPUT PAGE I can select my own theme to use, based upon my companies' logo, type face et al .,
Thanks and kind regards.
Phil Drury.

I'm trying to create an auto generating ID number field that contains a date followed by a sequential number for that date. In example...
YearMonthDay###
070719001
070719002
070719003
tomorrows numbering would be
070720001
070720002 and so on.
Each new day would start a new sequence of 001, 002, 003, etc.
I have searched these forums and haven't really found any answers. Could someone direct me in the correct direction. Also I need this number to be saved in the table and not just displayed or printed.

I get the message "The expression On Click you entered as the event property setting produced the following error: Class does not support Automation or does not support expected interface"
I receive the message on a PC running Windows 7 Professional using the Access 2013 Runtime. This pc does not have Access 2013 installed.On my pc, I do not get the error. I have Access 2013 installed and run Windows 7 Professional SP1. The "code" which gives the error is as follows and is invoked by clicking a button on a form
Code:
MsgBox "1"
Dim rst As ADODB.Recordset
MsgBox "2"
Set rst = New ADODB.Recordset
MsgBox "3"
[code]....
The error takes place after Msgbox "2" and before Msgbox "3".The strange thing is that I can run without a problem a sophisticated software package on the pc which gives the error, using Access 2013 Runtime. This package I converted from Access 2003.

How you automatically initialize a newly instantiated class?
So when you create a new instance it will run a procedure to set attributes.

I have two class variables (both arrays) among about 10 other class variables, that are not returning any values but "" for the string or #12:00:00AM" for a date. Here are my class variables:
Code:
'UPSData Class Module
Private p_LetterArray() As String
Private p_date() As Date
Private p_LetterArraySize As Integer
My Properties
Code:
'Properties
Public Property Get LetterArray(index As Integer) As String
LetterArray(index) = p_LetterArray(index)
End Property
Public Property Let LetterArray(index As Integer, NewValue As String)
[Code] ....
As I said, tLet and tDate result in "" and #12:00:00AM# respectively. When I step through the code, the values for tmp.LetterArray(0) is assigned "src" and tmp.UPSDate(0) stores "12/25/2013" correctly.
When I assign tLet and TDate, the same thing happens when stepping through the code. I'll use the LetterArray property to describe what happens:
Get LetterArray is called. p_LetterArray(0) does equal "src"
Let LetterArray is called. NewValue is "src" and p_LetterArray is "src" when End Property is highlighted in the debugger
Scope returns to Get LetterArray with End Property highlighted. In checking the values, LetterArray(0) = ""
Same steps happen with the same results ("12:00:00AM" vice "")

Any way to make objects to support adjusting continuous form controls making them unique in a sense to be able to change info like captions or whatever.
I've been working with collections for a while now tapping into event handlers such as the mouse inputs and or sizing of objects real time using collections but I can't seem to nail down any un-documented way to serialize controls on a continuos form.
I have tried when the new user creates the record adding another control to the collections class tying it to the id of the record but still this does not seem to be enough.
I do not know if there is a paint method or something of the sort I can override to get the desired results and most people without even trying will tell you this can't be done but how many have said that you can't move and resize objects in access but we are doing that now...

I'm using Access 2003. In "References" (Tools > References > Browse...), I've added in "Microsoft Windows Common Controls 6.0 (SP6)" (c:windowssystem32mscomctl.ocx).
I've then created/inserted an instance of the control "Microsoft ListView Control 6.0 (SP6)" on a Form ("MyForm") and given the listvew control the Name "MyListView".I wanted to decorate MyListView with some custom methods so I've created a new class module ("DecoratedListView") which contains a member field called "lvw".
I want 'lvw' to point/reference to MyListView, but I don't know what reference type to use in its declaration. Importantly, I also want to capture lvw's ColumnClick event.
I've tried:
Code:
Public WithEvents lvw As Object
Public WithEvents lvw As Control
Public WithEvents lvw As MSComctlLib.ListView.2
Public WithEvents lvw As MSComctlLib.ListView
Public WithEvents lvw As CustomControl
and none works when I
Code:
set lvw = Forms!MyForm.MyListView
The first try (Object) doesn't even compile. I get the exception "Expected: identifier"
The second try (Control) doesn't compile either. I get the exception "Object does not source automation events"
The third try (MSComctlLib.ListView.2) doesn't compile and throws the exception "Expected: end of statement"
The fourth try (MSComctlLib.ListView) compiles but fails at runtime with the exception "Type mismatch". Using TYPENAME() on the control returns "CustomControl".
The fifth try (CustomControl) compiles but fails at runtime with the exception "Object or class does not support the set of events".
I can't believe I'm the first person to have tried to capture an ActiveX Control's events in a separate class.

Basically I have a class event that works for all controls on any userform.
Its all working fine but I can't add an event to trap the click or mouse move of the userform itself.
Basically so when the cursor moves away from a control the label clears.
User Form Code
Code:
Option Compare Database
Option Explicit
'Define a collection and initialise the commandbutton event class
Private col As New Collection
Private newCmd As New clsEvents
[Code] .....
And here is the class Module
Code:
Option Compare Database
Option Explicit
'catch the event of Commandbuttons
Private WithEvents C0 As SubForm
'Private WithEvents C1 As CheckBox

I am trying to pass a boolean variable to a class module
Code:
Set rps.ViewS = View
the code in the module that this in theory is calling reads as
Code:
Private ViewC As Boolean
Public Property Set ViewS(ByRef ViewA As Boolean)
Set ViewC = ViewA
End Property
Public Property Get ViewS() As Boolean
Set ViewS = ViewC
End Property
However I am getting the error message
Quote:Definitions of property procedures for the same property are inconsistent, or property procedure has an optional parameter, a ParamArray, or an invalid Set final parameter.
