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?
I have data in a dictionary object and need to load it into a two column listbox. The VBA help says you can load data into a multicolumn listbox from a 2D array. So my question is how can I extract the data from a dictionary object directly into a 2D array.
The dictionary object stores data in key and item pairs. So the 2D array would have one dimension for the keys and the other for the items. I want to do this without having to extract the items and keys into separate 1D arrays and then loop through them to build the 2D array.
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.
I know the Dictionary Object is confined to the Microsoft Word Object structure though can it be used in Excel. If not, is there a suitable replacement.
I am using a dictionary object from the MS Scripting Runtime library to store a series of arrays and perform operations on the array cells as necessary. There is a for loop to go through the process of creating all of these entries. My issue is that when using the .exists property, it is returning a True even before the item has been added. Closer debugging indicates that the key is being added to the dictionary at the beginning of the for loop, even though no .add command is used and will not be used until the end of the loop. The result is that the values in the arrays do not totalize as intended.
Code for the dictionary build has been included below. I have attached the Excel file which contains the appropriate module which calls that function
VB: Option Explicit[ATTACH]46705[/ATTACH] Function DictAppTable(Loop_Range As Integer, Key_Range As Range, Dim_1 As Range, Dim_2 As Range) Dim DictTable As Dictionary Dim AppElement(0 To 0, 0 To 1) As Variant Dim iD As Integer Dim strAppID As String
[Code].... the previous post, as the pared down excel file which I posted had a slight error which prevented it from running
I already did this with excel formulas and it works pretty good. The problem is that when I work with lots (tons) of data, it takes minutes for the formulas to update and do all the needed calculations.
I have been trying to solve this problem using a dictionary object, since it should work faster. However; I don't even know how to start.
My problem (see uploaded Workbook) is this:
I need to calculate daily profits from different departments. For that I need to subtract daily expenses from daily revenues. Unfortunately, the order of appearance of the departments is random. At the end it should look something like this for every day and department:
Add - add key-item in dictionary object Exists - Check the existence of key in a dictionary object Items - Get the collection of all items. Keys - Get the collection of all keys. Remove - remove particular key-item RemoveAll - Remove all keys-items
Dictionary Object supports Properties Count - gets the count of keys Item - sets or gets the item Key - sets the key in dictionary object
Code: 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) Next 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.
I would like to get data onto my worksheet that looks something like what I have below. I'm pretty set on using Dictionaries to get the data into this format
(row 1 reads): header 1, header 2, header 3 (row 2 reads): value 1, value 2, value 3 (row 3 reads): value 1, value 2, {"property1": property1, "property2": property2, "property3": property3}
I'm close to doing so but having issues with my syntax.
I can refer to: arrExport(1)("key3") to get the value in key3
but I cannot refer to: arrExport(1)("key4")
Because key4 is what contains another dictionary.
Code: Sub DictWithinDict()
Dim dict As dictionary, dictValue As dictionary Dim arrExport() As dictionary Dim i As Integer
ReDim arrExport(1 To 10) 'real data will be in thousands
i have a sheet in template i use in preparing bid packages for electrical installations.it 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.
With a known X and Y, trying to solve for Z from a table. ie: IF a variable X is defined across a row, another variable Y defined down a column, the data field Z fills in-between. What do I need to use to interpolate for both X and Y to solve for Z?
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
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’?
I have a dimensional array / matrix that is current a 9 by X, where x depends on the amount of entries a user makes.
Anyways my question is that I have a sheet called "Database" and I wanted to know if there was a simple code to transpose my array on that sheet starting at cell "A2".
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?
I am currently using a macro which highlights keywords and associated page views from an array in my website stats spreadsheet. Now I need to take it to the next level:
I want to use a multi-dimensional array to pull out any keywords that are duplicated, and display them at the top of my spreadsheet with the totaled page views next to them in a different color (red).
Here is my existing Keyword highlighting Sub Highlight_Keywords()
Dim vntWords As Variant Dim lngIndex As Long Dim rngFind As Range Dim strFirstAddress As String Dim lngPos As Long
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.
Code:
Sub searchArray() Dim myArr() As Variant Dim i As Integer myArr = ThisWorkbook.Worksheets("Sheet1").Range("G1:G8594").Value For i = LBound(myArr) To UBound(myArr) Debug.Print myArr(i) Next i End Sub
I need to declare a two dimensional array that will return the Row and the cell's string value. My only solution is to return the row as a string like this.
Public GlobalArray(2, 100) As String
How to get more control than this? Maybe I should just declare it as a variant but this might open it up for problems later.
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
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 etc
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.
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:......
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).....
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...
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.)?
I have an array with dimensions (5000,30). I want to perform a worksheet function "Percentile" on specific columns within the array. So for instance I may want to know the element falling at the 50th percentile in column 5 of the 30 column array. Is there a way to do this without having to place the array onto a worksheet?
I have two dictionary objects populated with various keys and items - Dict1 and Dict 2. I've read that the items of a dictionary object can be quite varied, even another dictionary! I know how to add items to keys if those items are strings say, but how to add an entire dictionary (Dict2) as the items of another dictionary (Dict1)?
