Class Module
Feb 15, 2010
I would like to create a class module that it's the same as a connector shape (for example), but with additional custom properties defined by me. For example, I would like it to have a temperature property.
So, for example if I write in a Sub procedure:
Dim Test1 as EnhancedConnector
Set Test1 = New EnhancedConnector
A new connector appears in the activesheet, but this connector must have my custom defined properties available to VBA Code

I've created two modules, card and pack. Card has three variables (value, name, suit) and pack is made up of an array of 52 cards. Referencing it from a test module (NOT a class module) I expected to be able to use debug.print pack.card(32).suit to return the suit of the 32nd card. Instead I get an error message "Object or With variable not set". What am I doing wrong
Private p_strSuit As String
Private p_strName As String
Private p_iValue As Integer
Public Property Let Suit(strSuit As String)
p_strSuit = strSuit
End Property
Public Property Get Suit() As String
Suit = p_strSuit
End Property
Public Property Let Name(strName As String)
p_strName = strName
End Property......................................

What exactly is a Class Module? I've tried doing some searching on Google and haven't really found a straight answer as to what a class module is and what it is used for. How does it differ from a Normal Module?

I have two user forms, each with a checkbox for Jan-Dec. Also, I have a checkbox "All" to check/uncheck the Jan-Dec boxes. I also created a class module so that if any of the Jan-Dec boxes get unchecked, while the "All" box is still checked, it will uncheck the All box. Basically I just don't want the All checkbox to be able to be checked while any single month is unchecked. The only/easiest way I found to do this was with a class module, so I would not need to create individual Checkbox_Jan_Click() events for each month.
Now my issue is, I have 2 userforms like this. I'd like them to share the same class module, but in the class module I need to refer to UserForm1.CheckBox_All. So I need to dynamically refer to whichever userform was active, but as far as I can tell, this is not possible.

i would like to do is create a class module so that when the user double clicks on a label a msgbox will open saying the name of the double clicked label. If someone can get me to this point i can modify the code to suit my needs.
Some other things really quick though. I have 80 labels, but i only need this to work for labels 1 through 40 and the labels are on a multipage control within the userform.

I have written a public function inside a class module. Is there anyway I could call the public function in Excel? What is the exact syntax to do it?

I have a class module (MyCtrlEvents) with a sub (TxtGroup_Change) which I want to handle on a change event for some specific textboxes.
When the form is opening I don't get the correct sum for the textbox "TBSum601". It should be 200 but I get 14464
When I then also change a number in the form for any control like "TB7%", the change trigger event doesn't seem to occur....

I have a userform with a single blank multipage. At runtime additional pages are added, the number of pages depends on input from another userform. Six frames, containing labels, textboxes and comboboxes are then added to each page.
I need to be able to use the textbox and combobox change events of these dynamically created controls to perform lookups and calculations. Although I can name the controls at the time they are created, it is not feasible to write code specifically for each control (I can have over 1,600 text boxes distributed over 9 pages, for example).
Having searched for some time on how to achieve this I believe using a class module is the way to go. However, how to use a class module is just not sinking in I'm afraid.
HTML Private WithEvents mpTextBox As MSForms.TextBox
Private WithEvents mpComboBox As MSForms.ComboBox
Private Sub Class_Initialize()
Set mpTextBox = MSForms.TextBox
Set mpComboBox = MSForms.ComboBox
End Sub
Private Sub mpComboBox_Change()
MsgBox "ComboBox value has been changed."
End Sub...........................................

After all the awesome macros I've obtained with the help of all of you, I now have over 30 macros, each in its own module. I have tried without success to re-name the modules with no luck. How is everyone organizing these?

What i have at the moment is a module that contains code where i call a different module that i use as a procedure.
Module1
Code:
If Sheet1.Range("C4").Value < Sheet1.Range("A2").Value Then
If Sheet1.Range("K4") = "" Then
MsgBox "Please check 06:00 tasks not done yet!"
Cell = "Range(" & Chr(34) & "F4" & Chr(34) & ")"
If Sheet1.Range("C4") + 0.042 < Sheet1.Range("A2") Then
Run "EmailProSheet"
End If
End If
End If
EmailProSheet is what i call but now i want to use the variable "Cell" in the procedure as well?
Module3
Code:
MsgBox Cell
Set OutApp = CreateObject("Outlook.Application")
Set OutMail = OutApp.CreateItem(0)
On Error Resume Next
[Code]........
As it is now everything is working fine but does not return a value in "Cell" if the procedure is called. Is there another way?

I've created a class called CStock. It has 5 standard properties (with Get/Let methods) as explained in that article above. Nothing fancy here.
I also want to create a CPortfolio class that has 3 properties: pName, pNumberofPositions, and pHoldings. the first 2 are stardard, but the last one is different. I want it to somehow keep a collection of stocks.

In my Personal Macro book, I have 2 modules, one for Functions and one for "macros".
Is there a point where it's more efficient to make a new module (or is the opposite true and it's more efficient if they are all in one)?
Does having a plethora of sub routines in a module slow down excel even though the routines are short? or would having them in different modules slow it down more?

I have a Form that when the 'SUBMIT' button is clicked, I would like to validate the information and then write it to a 'MASTER SHEET'. However, the validation has gotten lengthy and I have opted to put the validation code in a separate Module to keep my general code a little cleaner.
PROBLEM:
The original code would kick you back to the form if something was wrong via a 'END SUB', but as now the SUB is on a different Module, it isn't working.
Here is the pertinent code on the general code sheet: ....

I would like to have an email generated when a cell changes to a particular value. I've developed the macro to send the email with a saved attachment.
When I try to OJT-Engineer the text for the module, I can't get it to recognize the macro. It's a syntax issue, it seems.
What I need is for my module to initiate a macro when a cell changes to a value.
This is the code EXACTLY as it appears:

I have 3 modules that all use the same Excel Workbooks, but just perform different actions in each module. It's such a waste of space! I was wondering if there was a way that I could combine all 3 modules into one module.
For example Module 1 is:
Code:
Dim Varbooks
Dim varBook
Dim wb as Excel.Workbook
Varbooks = Array("Fire", "Ice", "Alpha")
For Each varbook in Varbooks
'Run the below code
Next Varbook
Module 2 reads:
Code:
'declare all variables
CurrentPath = ActiveWorkbook.Path
varBook = Array (same varbooks as above)
'Run different code
Next varbook
[code]....
Varsheets (I use varsheets instead of varbooks this time only difference, but they are sheets inside a masterworkbook, as opposed to being workbooks themselves, but exactly the same names)
'Run a totaly different code here
Next varSheet
Is it possible to somehow combine all 3 of those into one module? I have tried, but I keep getting a compile error of "For Control Variable Already in Use"

I have code broken out between two different modules due to size limitations in a single module. I'm not able to figure out how to move to the second module after running the first module. I've tried something like this:
Sub FirstModule()
'Code
'Code
'Code
SecondModule
End Sub
Sub SecondModule()
'Code
'Code
'Code
End Sub
I'm getting an error that says "Compile error: Expected variable or procedure, not module". I understand that it's not allowing me to use the name of a module as a procedure, but I can't find any information on how to call the second module.

I defined function ConcatenateIf() in Module 1, that would take a range and combine the cell contents:
Function ConcatenateIf(iRange As Range, iLook As String, iNum As Integer)
For Each cell In iRange
If cell.Value iLook Then
ConcatenateIf = ConcatenateIf & Chr$(10) & cell.Offset(0, iNum).Value
End If
Next cell
End Function
Works beautifully. Then I save, and close. When I re-open, all the cells that reference this function display #NAME? error, like it can't find the ConcatenateIf() function. Does this have something to do with macro security? If so, why would it work at first, and then stop working?

I've got some code in workbook A that reformats another workbook B. Basically, it moves all the sheets across to A, creates a pivot table and chart, then saves itself as a variant of the original filename B. The last things it does is to delete the one sheet that was originally in A, and then delete the module that the code is running from (using some code from Chip Pearson):
ActiveWorkbook.VBProject.VBComponents.Remove ActiveWorkbook.VBProject.VBComponents("Module1")
The fact that a module can delete itself blows my mind - but there are a couple of things I'm not sure about:
1. Presumably anything that's in my sub after the delete module line won't get executed?
2. If the saved-as workbook (Bvariant) is closed without saving, the module is still there when it is reopened. Is there a way to prevent this without putting new code into Bvariant?

i am going to ask is for my curiosity only and to be sure that no one will break my password.
If the VBA module is locked for viewing and password protected, it can't be cracked??I asking this, because i made an excel application with macros, and i don't want the user of it to crack my password.
I have to mention that the password is 17 letter+spaces long.
I repeat again....i asked this ONLY for my application safety.

This module consists of app. 25 sub routines. Every sub routine is a For-Next Loop, with 70 For-Nexts to work through. The loops check certain input cells and if these cells are empty, the row is hidden. I have the reverse also where I can unhide these rows.
When I had about 8 of these loops in this module, it would work quite fast and it took about a second to run one of these subs. Now that I have 25 if I run one of these subs it takes about 20-30 seconds.
Before I break them all down into individual modules just to find out it doesn't work, is there anything else I should be doing or could try to speed these subs up? If breaking them down into more than one module is the solution, how do I do this best?

I declared a constant like so:
Public Const iFirstRow As Integer = 6
I figured that any time I used this, at least in the same module, its value would be 6, but it was 0.
I changed it to ModuleName.iFirstRow, which seemed to set it straight.
Is this just how it is, or am I doing something wrong that is preventing me from using it without the module name?

I have been trying many different commands to run a module from a userform, but nothing is working. I'm sure it's possible, right?
Basically, I'm trying to run modules based on a selection made via a listbox.
