UserForm ListBox Being Double-loaded
Jul 16, 2009I'm having problems loading data into a listbox. When the form first opens, it loads the data twice. I can then kill the form and restart it and the data is in there three times. I can't see any loading problems with the userForm_initialize routine. How can I ensure that the listBox is empty before I start adding data? This would also seem to be necessary prior to loading a different set of data into the form - correct?

Macro To Force Format And Check Barcode Check Digit
Nov 27, 2009My company uses 4 types of barcodes 8, 12, 13, & 14 number barcodes for our products my problem is that I can't figure out how to force the barcode to format properly no matter how somebody enters it if they don't use spaces or put them in the wrong spots, I can't use custom formats because there is 4 different layouts
8 digit should be "#### ####"
12 digit should be "###### ######"
13 digit should be "# ###### ######"
14 digit should be "# ## ##### ######"
these barcodes are in columns L, M, & N also right now 'm using a formula in another cell to verify the barcodes by calculating the check digit and comparing it to the check digit typed the formula i'm using is

Check All Check Boxes With CheckBox
Sep 9, 2007I am creating a userform with 10 checkboxes. The first 9 checkboxes are user options. I want the 10th check box to be a "Select All" option i.e. if the 10th checkbox is checked all the other 9 options are deemed to have been selected.
The way I want the display to work is that if the 10th checkbox is ticked all other checkboxes are cleared. Also if the 10th checkbox is ticked and any of the other check boxes is selected then the 10th checkbox should be selected.
I have tried coding this up but the checkboxes don't seem to operate as desired. I placed some code on the click event for the last option button to set the vlaue for all other buttons to false. This works but the 10th check box doesn't get ticked itself. When I try to code up the other bit I get similar issues.

Jul 28, 2009I have written a class that can be used as a replacement for Application.FileSearch in Excel 2007, that will take the same parameters etc. with no, or minimal code adjustments.
How do I now alter this so that it can be used as an AddIn by others?
I think that I have to remove all the sheets apart from 1 from the document, and save it as an .xla, but I am struggling with making this an addin, and then being able to use the addin from other code.
Does anyone have some instructions or a link to a website that could direct me? I have done a google search, but search for Excel, VBA, and classes (as well as AddIns), just gives lots of links to classes (as in teaching).

Class Module
Feb 15, 2010I 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.

A new connector appears in the activesheet, but this connector must have my custom defined properties available to VBA Code
Class Of Permutations
Jul 23, 2007I am creating a class of permutations. The problem is that there are many ways to describe what a permutation does. for example.
Dim aPerm As New clsPermutation
Dim bPerm As New clsPermutation
aPerm.DoesTranspose(2,3) : Rem aPerm.Action({a,b,c}) = {a,c,b}
MsgBox (aPerm Is aPerm.Inverse)
I want the message box to return True. But since aPerm and aPerm.Inverse are different instances of clsPermutaion, it returns False. (.Inverse is a read-only property that returns a clsPermutation.). What I would like to do is have a collection, myPermutations. When I specify the action that aPerm does, I would like
1) if nothing in myPermutations does the same thing as aPerm, then add aPerm to myPermutations.
2) if something (xPerm) does the same thing as aPerm, then
Set aPerm=xPerm
so that "xPerm Is aPerm" returns True.

Determining Class Using Grades
Nov 25, 2013I am trying to figure out a simple formula on determining class for students according to their achievement /grades.

Calling Routine From A Class In Add-in?
Feb 4, 2014I've got three workbooks that end users will be using for data entry. The VBA code for the three workbooks is identical.
I'm trying to encapsulate the code into an add-in so I only have one copy of the code that I have to debug/maintain.
Furthermore, I've also encapsulated the code in the add-in into a class. The class isn't really a "usual" object modelling some data; rather, it's a utility class processing Worksheet_Change and Worksheet_Activate events. Hopefully this isn't a really bad idea, rather than keeping the code in standard modules in the add-in.
The application is called "Midas". Here are some code excerpts:
Midas.xlam:
Standard Module:
[Code] ......
Class Module:
[Code] .....
And in the end user workbook:
[Code] .....
The Wbk_SheetChange event handler is triggering, but it's looking for the code in the end user workbook, instead of the class. Is there a way I can change
[Code] .....
to call the private routine "Cases_Changed" (where "Cases" is the sheetname) residing in the class instead of looking for it in the workbook?
