Declaring Public 2 Dimensional Array In Userform

Apr 22, 2014

i'm trying to develop an array that is populated when a userform is activated. The userform has a command button that when pressed, will cross check the information filled out in the userform with the entries in the array. If there are no matches then the array is ReDim and the new information is added to the array. Once all the entries have been made. The array is then transposed to a sheet titled "Database". My problem is that vba is not allowing me declare a public array.Below is the first part of the code. Which is when the userform is activated.

Private Sub UserForm_Activate()
With Sheets("Resources")
cbZIP.List = .Range("A2", .Range("A" & Rows.Count).End(xlUp)).Value
cbBED.List = .Range("B2", .Range("B" & Rows.Count).End(xlUp)).Value
cbBATH.List = .Range("C2", .Range("C" & Rows.Count).End(xlUp)).Value
cbSTABRV.List = .Range("G2", .Range("G" & Rows.Count).End(xlUp)).Value
End With

Declaring Public Variables

Apr 19, 2007

how do you declare public variables? In one of my forms I declare the variables but for some reason can not access them in other forms.

Public Rm_new As Integer
Public Angle_new As Integer
Public Pl_new As Integer

Public Sub cal_graph_Click()
'Stating variables
Rm_new = text_rm.Text
Angle_new = text_angle.Text
Pl_new = text_length.Text

Creating A 2-dimensional Array From A 1-dimensional List

Nov 27, 2008

I've been a lurker on this forum for a long while and it's always been able to provide me with lots of excel tips, and for that I am grateful! But this time I have a question that I can't find the answer to here, or anywhere else on the web after a few hours of looking. As a note, I'm not very experienced with Excel, probably somewhere between novice and intermediate.

What I need to create is a 2-dimensional array of data. The vertical (y-axis) are the tools, and the horizontal (x-axis) are the jobs. Where the y-axis and the x-axis intersect, will be the quantity of tools needed for that specific job. There are almost 1500 tools, and 100 jobs.

Declaring A 2D Array

Jan 21, 2007

where the number of rows and columns depend on other variables?

For example: In sheet 1, I have mentioned A = 2 and B = 3.

In the macro, I declare A and B to be integers. Then I try to declare a 2D array as follows:

Dim AB(A, B) As Integer

During compiling, it gives me an error: "Compile Error: Constant Expression Required" with the above line highlighted. What am I doing wrong?

Also, when I declare an array AB(4, 7), 4 is the number of rows and 7 is the number of columns, right?

Creating Array From 2-dimensional Array

Nov 28, 2011

I'm new to arrays. They seem promising for what I want to do though...

Heres where I'm at. I have some data like this:

items freq 1 0.5 2 0.5 3 0.5 4 0.25 5 0.25 6 0.125

Now, I've created a 2 dimensional array, as such:

Sub testarray()
Dim arr1 As Variant
Dim rng1 As Range
Dim lngX As Long

Set rng1 = [A2:A6]
ReDim arr1(1 To rng1.Count, 1 To 2)
For lngX = 1 To rng1.Count
arr1(lngX, 1) = rng1.Cells(lngX, 1)
arr1(lngX, 2) = rng1.Cells(lngX, 2)
End Sub

Now, what I need to do, is create an array for each freq of all the items that share that freq. Essentially I need this:

0.5 {1,2,3} 0.25 {4,5} 0.125 {6}

Now, I was thinking, if I could create a dictionary object and make the key the freq (so my keys would be 0.5,0.25,0.125) then I could assing the "item" an array (or another dictionary) holding the items that apply to that freq.

Variable Declaring. Textbox On Userform To Show Value Of A Cell

Sep 25, 2006

Users select a row number which then opens up a Userform. Comboboxes and Textboxes on this Userform are then populated with coloumn values (dependant on the row initially selected). If the row number was the same each time I could accomplish this by the following.

Private Sub TextBox1_Enter()
TextBox1.Value = Range("a1")
End Sub

but as its a variable I'm trying the following (which I think should work)

Private Sub TextBox1_Enter()
TextBox1.Value = Range("a" & edi & "")
End Sub

I think I need to declare the variable 'edi' as Public. If so where should this be? I've tried 'Genereal Declaration'

Finding A Value In 2 Dimensional Array?

Jan 15, 2014

i have a sheet in template i use in preparing bid packages for electrical relates to locating in a (building) grid the locations of the motor control (mcp) and power panels (cdp).my desire at this point is to find a way to local a unique value (mcp or cdp) in a 2d grid and then return the column and row names from the same grid. eventually this information will populate a table of all the mcp's and cdp's with their locations.

my sticking point appears to be finding a unique value in a 2d table. this value can be anywhere in the table, not just the first column.

i've tried the lookups and index/match. match fails when i extend the lookup_array beyond the first column.
not sure if this is even possible.

Function For 2-dimensional Array

Feb 27, 2007

I am trying to write a public function that fills a table for a 2-dimensional array and am having trouble with my named ranges. The x-axis is based on years (range F2:O2) and the y-axis is a q_factor (range E3:E23) so the data range would be (F3:O23. The following outlines my logic:

Public Function bondValue(years As Range, q_factor As Range, z As Double)

Dim nRow As Long, nCol As Long
Dim bondPort As Range

nRow = q_factor.Rows.Count
nCol = years.Columns.Count
sumTau = 0

Populating A Multi-dimensional Array

Nov 26, 2008

I have a spreadsheet which I will be adding to over time. I need a macro that will look for the last 10 rows and then pull together a summary table based on data from several of the columns on each of those rows.

I've tried to go about this by using an array. The array will always be the same size (it will always be 10 by 11, i.e. EngineArray(10,11)-basically the same size as my summary table). I've also set Option Base 1.

What I’ve got so far is below. It isn’t working properly though. To start with I was getting ‘type mismatch errors’. Now instead of reading the numbers from the selected cells into the array, it just changes all the cells I’m trying to read from to ‘TRUE’?

Summing In A Multi Dimensional Array

May 15, 2007

I've created an array that is 60 pairs of cells wide. Each row in the array represents a different account. The 60 pairs of cells contain up to 60 payments in a payment stream. The first cell of each pair may contain an amount of interest to be paid, or zero if the time band in which it was/will be paid is not within the time range that I'm evaluating. The second cell of each pair may contain a number between 1 and 10 representing the time band in which the interest will be paid, or zero if the payment date falls outside of the time bands.

I need to be able to sum the interest to be paid in each time band for all of the accounts in my database.

Is there an Excel function that I could use or will I need to write some VBA code to loop through each row?

Fill ComboBox With 2 Dimensional Array

Oct 9, 2004

I can set up a 2 dimensional array by using

array = Workbooks("Workbook.xls").Worksheets("Data"). Range("D_all")

as range D-all contains 2 columns and 20 rows

I can send that list to a combo box by using

Me.ComboBox1.List() = array

If I have ColumnCount set to 2 then both columns will be listed

If I have ColumnCount set to 1 then the 1st part of the array will be listed

But how do I list just the 2nd part of the array

How To Dim Array And Its Values As Public

whatever(1) = "somethin else"

Public Array Not Avaiable In Sub?

Jul 17, 2007

I've got two public dynamic arrays being declared in a module attached to my workbook. I then have a sub that runs off a userform in that workbook which populates and redims the arrays preserving the data. Next I activate a PowerPoint application and insert some tables into which I want to put the data in the arrays but when I refer to the arrays (admittedly in a Sub called from the first Sub) I'm getting a 'subscript out of range error'. I can print out the data before I call the second sub and it's fine. I've worked with public variables before and never had this problem. Do I have to call the public variable differently if I'm curretnly in a different application (i.e. PowerPoint)?

Inserting Dictionary Object Into One Dimensional Array?

Mar 30, 2012

What I'm trying to do:

1) I have data that has a header row of 6-10 values (created, action, type, id, ...). The rows are unique records.
Click here to see the data

2) I originally wanted to read the data into one array (DataArray) and the header into another array (KeyArray). Then I would add additional unique information about each record (additional columns of info) into the DataArray.

3) I stumbled upon Dictionaries as a way of storing key/item pairs, which I thought could apply to each record since the headers are all unique and would be a way of storing key/items without needing to:

a) Know the ordering (if I used arrays I had to know the upper bound of the array to insert a column
b) Look up which what position in the array mapped to which column header
c) Resize the array every time I wanted to insert a new column of information on all the records

4) So now that I know about a dictionary object, I believe I need to create one Dictionary object for EACH record (row) of my data and then store those Dictionary objects within a one dimensional array such that each element of the array is a Dictionary.

5) This way I can iterate through each element of the array to access the dictionary inside and perform calculations on each record, depending on which key/item I needed to work with at a later point

Questions for Dictionary experts:
1) Is my approach sound?
2) What is the syntax for putting the dictionary of one row's worth of data into an element of a one-dimensional array?

Retrieve Content / Values Of One Dimensional Array

Sep 15, 2012

I'm trying to make this piece of code work to no avail yet... Every time I run it, the compiler pops up with Error #9: "Subscript out of range". The range consists of hundreds of cells in 1 column with geographic coordinates formatted as "General". Like this: myArr(38.91472, 37.20318, 38.63824, etc.). Tried to re-format the cells to "Number" - doesn't work either.

Dim myArr() As Variant
Dim i As Integer
myArr = ThisWorkbook.Worksheets("Sheet1").Range("G1:G8594").Value

Data Type Of Coordinates Of 2-dimensional Array

Apr 29, 2007

I have a big array "DataArray" and want to access it:

For i = 1 To 4
variable = DataArray(SourceArray(i))
Next i

"DataArray" has two dimensions, so SourceArray has to consist of data like this:

SourceArray(1) = 1,2
sourceArray(2) = 2,4

What data type does Sourcearray have to be? Integer doesnt seem to work, and DataArray doesnt like a string as coordinates. I have a workaround with two different arrays of integer for x and y coordinates, but this cannot be it.

Fill Range From Multi-dimensional Array

Jul 20, 2007

I searched and found a few posts about transposing arrays into a range of cells, but none of them seemed to solve my problem. So, my problem is, I have a .Net assembly which provides various functions to allow Excel to access our Oracle DB stored procedures/tables, etc. This assembly is exposed via COM Interop. I call the GetSPINTypes() method, which returns me a list of type pairs (ID, Name), in a CSV string format.

I split the CSV into rows, and then put each row into a 2-dimensional array.
I then need to dump that array into one of my sheets in Excel, so I try to do the usual Range.Value = Array, but this sometimes tells me there is a type mismatch, and most times just doesn't fill the range. I've checked my arrays in the watch window, and they have definitely been filled in correctly, the values just don't appear when they are put into the sheet. See the code I'm using below:......

Multi-dimensional Array Not Showing In Listbox

Aug 18, 2007

I have made the function below to return a variant multidimensional array. I pass the function an array of folder paths that I wish to search through looking at subfolders within that path where their name matches a search string that I pass to the function. eg., it will find a folder named "Catnap" if you pass the string searching for as "Cat*".

The size of the array it builds depends on how many folders it finds that match the search string and so needs to be built dynamically. Hence, I believe it builds a 2 dimensional array horizontally and I transpose it at the end of the function. In each element I put the folder name that was found in the first dimension and the path to that folder in its second dimension.

I have a 2 column listbox on a form that I set this array to. eg., Me.ListBox1.List = DirPaths("C:","Cat*",vbDirectory,100)

This works fine and shows a list of folder items found by folder and path in the two columns of the listbox if there is greater than 1 search found. However, when the search only finds 1 then the listbox shows the folder name with the folder path in row 2 of the list box. (See below).....

Evaluate Multi-Dimensional Array Matrix

Feb 27, 2008

I'm trying to use VBA to do some matrix processing. I have successfully done matrix processing in the spreadsheet, but I'm looking to port the logic into VBA to more easily reuse central formulas and reduce the amount of code in the spreadsheet.

The function shown below works. I had to hack around the variable declarations to eliminate processing/compile errors but it seems to function (no pun intended).

While debugging I noticed that this function would seem to get called 4 times. I do have other modules running, although I don't think any other modules are affecting this.

After some input from shg, I updated the variable declarations, but I'm getting an "Overflow" error reported. Sometimes (not always) a divide by zero also pops up. I do have the Msgbox for errors at the end, I haven't tried removing that part to see if the error reporting vanishes. I'm not sure 'hiding' error alerts is the best thing to do anyway...

Join Dynamic Multi-dimensional Array

Apr 15, 2008

the built in "Join" function can join all elements of a 1-dimensional array into a string with delimiter. Now, how do I do that with multi-dimensional array if I just want to join 1 dimension of it.

For instance, I have:

m = 10
n = 20
Redim my(m, n)
'assign values to array here...

'I want to join, say, my(5, 0 to n) only
'How to do that without declaring a new 1 dimension array?

Also, I want to write a join sub/function to do the above for n-dimensional array, do I need to write each one for every number of dimension (1 sub for 2-dimension, 1 sub for 3 dimension, etc.)?

Public Array Not Clearing Between Runs

May 19, 2008

I have a public array in a module in my spreadsheet. The array is an array of a class type (not integers, strings, etc). When I run the macro that uses the array for processing the first time, everything seems to work properly. However, if I run the macro a second time WITHOUT getting out of Excel and coming back in, it doesn't come back with the proper results. It seems like either the array isn't being cleared out properly between the macro runs, OR that something in the macro is overwriting memory. Is there a way to make sure the array is being cleared out between runs of the macro?
