Why Declare The Variables
Sep 17, 2009I know that we should declare all variables at the beginning of a subroutine, in fact I'm told it's good practice to use Option explicit to 'force' variables to be declared, my question is why?
If I don't declare a variable the routine still seems to work OK so what is the downside of not declaring them upfront? Is it just for neatness or common practice or is there another reason?
Which Variables To Declare
Dec 10, 2008As a rule which variables should I declare?
Sub checkPO()
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
Application.EnableEvents = False
Dim Rng As Range, MainSheet As Worksheet, item As Variant ', CurrWidth As Integer, UnitWidth As Integer
Set MainSheet = Sheets("Orders To Chase")
Set Rng = MainSheet.Range("B5", MainSheet.Range("B60000").End(xlUp))
totalqueries = MainSheet.Range("B5", MainSheet.Range("B60000").End(xlUp)).Cells.Count
UnitWidth = 282 / totalqueries
With progbar '\displays the please wait box
.Show False
.prog.Width = 0 '\ updates progress bar
.Repaint
End With
If I declare the variable my progress bar goes off screen. remove it and its back to within its box.
I haven't declared any of these variables either. Does this matter?
POnum = .Range("G5").Value
Supplier = .Range("A5").Value
Req = .Range("B5").Value
Ordered = .Range("E5").Value
Declare Set Of Valid Variables Acceptable?
Oct 25, 2013i need to set the range of variables that user can add to the range.
For Example:
AA_*
BB_*
CC_*
ABCD_*
so we accept variables STARTING with AA_ OR BB_ OR CC_ OR ABCD_. If the user enters sth else, then I want to disable the "Enter" key. (If the Cell is Empty than it is also OK!!)
If disabling the Enter key is not possible then maybe i can use Conditioning Formatting? But the question is then if i can use for single condition OR statement.
Match And Copy: Declare The Variables Correctly And Have The Operations Done In A Series Of Do/ Loops Or For/Nexts
Feb 2, 2007I have a series of operations to carry out and, while I can do the code for each individual one, how to declare the variables correctly and have the operations done in a series of Do/ Loops or For/Nexts. Especially the declaring of named ranges as variables. Also a bit uncertain of the best way to find and coy the match. I have attached a simplified version of the workbook, with explanations on it.
Basically what I need to do is loop through a series of named ranges and then loop through the names in each, match each name with a name in a master list (with a flag as an image), add an e-mail hyperlink to that flagged name and copy both to a new cell.
Constant Variables - Declare Name In Separate UserForm As Constant
May 8, 2012I have a userForm (Form1) that contains a persons name that I would like to reference in a separate UserForm (Form2). In the separate UserForm (Form2) I need to reference this persons name many times, so I was wondering if there was a was to declare this name in the separate UserForm (Form2) as a constant. Only thing is that a constant, to the best of my knowledge, must be an expression and not a variable. Mainly, I'm trying to avoid declaring the myName variable in each Sub within Form2, which it will be needed for a ton of Sub's.
Code for Form2: Const myName As String = Form1.txtName.Value
Declare Multiple Subs On 1 Line Just Like Multiple Variables
May 25, 2014I'm making a Form with multiple pages and on every page there are atleast 36 Textboxes.
[Amount] [Description] [price]
I want to run a small sub updating the price on changing the amount. My code now looks like this:
Code:
Private Sub TextBox1_Change()
Call UpdatePrice
End Sub
Private Sub TextBox2_Change()
Call UpdatePrice
End Sub
Private Sub TextBox3_Change()
Call UpdatePrice
End Sub
I have to do this on 8 pages, 24 to 36 times, which makes the code extremely long. Is there a better way to do this?
Something like:
Code:
Private Sub TextBox1_Change(), TextBox2_Change() etc...
Call UpdatePrice
End sub
VB Classes In VBA
Dec 23, 2008I'd like to create a number of classes in a VB.NET DLL and then use them from VBA in Excel 2003+. Is this possible? I wouldn't actually expose any of .NET. These would be simply be classes defined by me (which may wrap elements of .NET but never require VBA to have knowledge of .NET or access to .NET assemblies).
If this is not possible, would it be possible to create a DLL in VB.NET that exports functions and subroutines that can then be linked into VBA by importing them (the same way you would with Win32 API routines)?
MS Training/classes
Sep 21, 2008I am interested to get some opinions/input on where one might obtain Excel training/classes, etc. Our local college infrequently offers classes and when they do, the class is most always entry level which I have already taken. Online or correspondence would be acceptable.

350 People Tracking 24 Dates For Classes Each
Feb 20, 2009I have a spreadsheet with ~350 people tracking 24 dates for classes each. On a seperate tab I have a macro that copies and pastes a pre-defined macro to display the due dates. My question is, can I have a macro run the calculation and put the result in the cell rather than have around 8,400 calculations on a sheet?
View 9 Replies View RelatedRaise Event From One Of Custom Classes Instead Of Calling Sub?
May 2, 2014I can create events in my custom classes. When do I even want to raise an event like this instead of calling the corresponding Sub?
I imagine that I can create an event called OnColorChange or I can create a sub called OnColorChange.
Why would I want to create an event?
Enter & Exit Events In Control Classes
May 11, 2006A lot of people seem to have been having troubles with the fact that if you try to use controls in a class with the "withevents" keyword, some events (like Enter & Exit) are not included in the tracked events. I have been having some troubles with this myself & have not yet seen any particularly satisfying workarounds to this problem.
So here is an idea I just had, I have not made any attempt yet to implement it & so have no idea how complicated doing so would be, but I thought I would just put it out here & get some feedback on the idea before I spend any real time working on it.
The idea is to create a blank, transparent label that covers the entire form, monitor the Click event of this label, & pass it back to the normal controls on the form as necessary. Does this sound doable, or do you all think it would be merely an exercise in futility? If anyone has any better suggestions for how to work around this lack of events,

Mar 12, 2007This is a double IF() to me. I just can't figure it out.
I download a list of classes taught by a number of teachers. I want to summarize how many of classes taught by each teacher.
I have tried many variations of countif() but can't seem to figure out how to do both.

Declare Constant
May 15, 2007what does the symbol # means in VBA? (but I couldn't put the # in the subject of my message )
I'm trying to understand someone's code... at some point he wrote:
sum_LU_Area = 0#
I thought that the # was used to declare a constant but I'm not too sure because in his code earlier he declared
Public sum_LU_Area As Double
Beside, sum_LU_Area is calculated somewhere further in the program.
Declare And Initialize An Array?
Mar 23, 2009I am running into the error, "Procedure too large". I know I need to break the range down into Arrays, so how can I hard code the values into an array? I cannot find an example to follow. Ranges: D:E,K:L,O:P,....etc. I know I can break the rows up into an array too, but one thing at a time. Here is an example of the range for D:E.

Function Back Variables: Function Give Two Or More Output Variables
Jul 27, 2006Can a Function give two or more output variables. e.g.
Sub a()
x = 5
result = Y(x)
End Sub
Function Y (x As Integer) As Integer
Dim B
B = ... * x
Y = ... * B
this will give back Y as a result. But if I want to get 2 or more output variables (let's say I need to get also B into sub) from one function, how should I do that?
I need this because function works with large matrix and I want to extract some values appeared in between.
