Declare And Initialize An Array?

Mar 23, 2009

I 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.

Initialize A Variable

Jun 11, 2008

Option Explicit

Dim mdNextTime2 As Double
Dim mdNextTime1 As Double
Dim mdNextTime As Double
Dim myCount As Integer
Dim myC As Integer
Sub
If (myCount Mod 5 = 0) Then
end IF
end Sub

Now, when myCount is multiple of 5 it should go inside that loop.
Instead it goes inside immediately, also when myCount = 0
So I decided to initialize myCount to 1.
But the strange thing is that I don't know how?

If I write:
Dim mdNextTime2 As Double
Dim mdNextTime1 As Double
Dim mdNextTime As Double
Dim myCount As Integer = 1
Dim myC As Integer

Or....................

Global Variable Or Pass Variable Between Sub-routines

Jan 26, 2007

The first goes through a directory and opens all the files.. after it opens a given file it goes off into a sub-routine to process the data in that file.

I am trying to create a counter in the first sub-routine and then pass that value into the second sub-routine to tell it to put the values out on the next row down.. so the first time through it puts the values out on row 1, next time it puts them out on row 2, etc.

Setting A Global Variable

May 27, 2008

If I want to set a global variable when I open my workbook which will be used in code on the individual spreadsheets, how would I do this? I want to set the time the workbook is opened to a variable (constant) and then compare that time to current time on each calculation in the worksheets.

I'm using Excel 2000.

Global Variable Declaration

Dec 25, 2007

I have a smattering of experience within various programming languages, but am still coming to terms with the basics of VBA. I am trying to declare a global variable, assign it a value, then use that global variable. Within 'ThisWorkbook' I have the following...

Public myText As String
Private Sub Workbook_Open()
myText = "Hi There"
End Sub

...and in the Microsoft Worksheet Object Sheet1 (Sheet1) I have...

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
MsgBox myText
End Sub

Now, my understanding of this code is that upon opening the workbook, myText variable will be declared, and then assigned the value "Hi There". Then, once I have clicked anywhere on Sheet1, a message box will appear stating "Hi There". Problem is, the message box is blank. This is all fine, except I want the message box to state "Hi There". What am I doing wrong? Is the variable declared (publically) correctly? Am I assigning the public variable the value correctly?
Am I referencing the public variable correctly in the Worksheet_SelectionChange procedure correctly?

How i can resolve that?, i.e., How i can use a global parameter in a userform and the same global parameter in the modulo with the same data?

A Variable Which Is Used By Several Subs In A Worksheet But Is Not Global?

Dec 7, 2008

I am working on a workbook which uses a large number of variables. I am trying to keep them as "local" as possible to keep it simple. Some of my variables are local to the subs they're used in. Some are global as they're used by subs in several sheets. A third type of variable is used by several subs all belonging to the same sheet. Is there a way of declaring them so they're known by all subs in that sheet, but not by every sub in the workbook?

Setting Global Variable From A UserForm

Jul 31, 2009

I have a UserForm that runs when my excel project starts that prompts the user for two pieces of data: a username and a password (these are not for logging into the file itself, I need to use them to call web queries later). I want the UserForm to store both of these data in global variables, so that macros that are run in the future can refer to them and read their values. Unfortunately, I am very new to VBA and I cannot figure out what code I need and where exactly I need to put it. Here is my current code, where "authentication" is the name of the UserForm object, and the textboxes I use for entry are named "user" and "pass": In "This Workbook"

Excel 2010 :: How To Match Worksheet Names Against Global Variable

Jun 10, 2013

I would like to ask the user if when the name the worksheet the same as an already existing spreadsheet tabe if they would like to overwrite it or unload the user form.

I am not sure of two things:

1. how to find the already existing tab?

2. Once I find out how do I programatically delete it, so the code can continue

The code below works with the exception of the last section (trying to achieve the questions stated above).

I am using Excel 2010.

Code:
Private Sub CommandButton1_Click()
If TextBox1.Value = blank Then 'Need name for processing
MsgBox ("Name must not be blank.")
Exit Sub
End If
If Len(TextBox1.Value) > 12 Then

Why Declare The Variables

Sep 17, 2009

I 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, 2008

As 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 Constant

May 15, 2007

what 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.

How To Exit From Userform Initialize

Jun 5, 2013

I have two userform combo boxes, the second follows up on the results of the first.

The second Combo Box looks for incomplete fields and provides them in a drop box. If the data the second Combo Box is looking at (This is different data than the first Combo Box is looking at.) is complete it updates the field, if not then it adds it to the drop down list.

My problem is this, if it finds everything updated and nothing is added to the drop-down list, how do I exit? I just want a complete break where all programming ends.

I am in the Initialize subroutine and I have tried Exit Sub and it still brings up the user form.
