Create An Array In VBA
Dec 20, 2006I am trying to create an Array, and have searched through many threads on this website and realise I don't have a basic understanding of Arrays. Specifically the ReDim Array function.

View 2 RepliesI have a doubt, in VBScript for excel is possible create an associative array?, for example:
PHP Code:
Dim columnValue(26) As Variant columnValue("A") = 1 columnValue("B") = 2
So if I want to know the value that corresponds to the letter B the result must be: 2
MsgBox columnaValor("B")
I have attached a spreadsheet of data that I would like to reduce.
In the workbook there is a set of data (rows 1 - 24) which are defined with random dates (row 2) and number criteria column A.
In the table below that (rows 28 to 37) I have set out how I would like to present the data. how to create an array formula that sums the above data months into the criteria of column A.
Array set for workbooks? I have more than 10 workbooks to update
refer to attachment. the VBA code is in Consolidation SOP.
I have an array which I would like to extract the information and put it in a table in a spreadhseet. Does anybody knows a faster or better way to do it different than using a for next?
View 2 Replies View RelatedAs part of a larger formula, I need a way to evaluate a range row by row and generate an array with the results. More specifically, I need to evaluate whether at least one of the cells in a row has a specific value.
So given the following table:
1
1
1
2
2
1
2
2
3
3
When querying the table for the value "1", it should result in the array {TRUE, TRUE, TRUE, FALSE, FALSE}.
How can I achieve this?

I have the following problem:
In cells A1 to A4 I have 4 numbers (8,7,12 and 15).
In cells B1 and B2 are the numbers 1 and 4
Now I want to use the max function to find the highest value in the cells A1 to A4. But instead of typing =max(a1:a4) I want to use other cells that tell excel where to look. What I exactly want is to say =max("a"&B1:"a"&B2) because in B1 and B2 the rows are indicated from which to which excel shall find the maximum.
I have a dynamic number of rows each with three colums of values. These varaibles I want to fill an array with but I don't know how.
Now I've just "concated" these three variables into a string and then I intend to split the string into rows by the third comma. (see below)
I think it's easier though to use an array and I really appreciate some assistance. Please tell me also the best way to sort the array. It will be sorted by var_Status which is an integer. (sort order: max positive to max minimum)
PreString = PreString & var_StartWeek & ", " & var_Status & ", " & var_Totalh & ", "
I am fairly new to VBA, i require some help creating a Standard Deviation UDF using arrays, i have made a userform that allows a user to select anywhere between 1 to 30 companies (A1: AD1) and its corresponding stockprices (A1:A60) in a sheet called companydata, using the following sub, my problem is that i am unsure how to create a function using the info the user selects. I have also created a returns function (below) but this is vba is saying that there is a out of range error, Will anyone be able to help please.
Below is the code i am using to allow for my sub: ....
I've created a range B3:B12 in which each cell returns TRUE of FALSE. There corresponding values are listed in C3:C12. I have the same thing again in D3:D12 and E3:E12. Checkboxes link to the TRUE/FALSE cells. Attached is a stripped down file to show this.
I want to create a formula that lists each item in the one cell (no spaces required inbetween) for use with a search. I know a long winded way to do this involving many IFs but any array will be much more tidier, thing is I hardly use arrays and have struggled with this one.
I'm thinking it will be along the lines of =IF(B3:B12="TRUE",C3:C12,"")&IF(D3:D12="TRUE",E3:E12,"") but exactly what it should be is beyond me.
EDIT: The original file attached was corrupt for some reason, the new attachedment is the same except instead of TRUE/FALSE cells I've set them to 'x' for quickness (lost my work...!).

I'm trying to create a single array from multiple ranges... I'm not sure what syntax to use:
Code:
Dim dat4() As Variant
Set r = Sheet13.Range("rsqlassetid")
Set r2 = Sheet13.Range("rsqlparentcat")
dat4() = (r , r2)
I can create an array with multiple columns from a range if the columns are next to each other but in this instance they're not.
These 2 ranges both have the same number of rows and I'm trying to combine them into a 2 column array, but not sure how to make it work without looping, rediming the array and using a secondary array to preserve the data...
I got the following code:
Code:
Function DateiAuswaehlen() As Variant
Dim FileOpen As Variant, i As Integer
Dir Left(KonvPath, InStr(KonvPath, ""))
[Code]...
Basically, I want the function to return an array, but also work when the user does not choose any file.
I have a sheet of data that I can filter (e.g. only show male pupils).
On the next sheet I want to display the list of filtered results with no gaps.
As the user will be able to select which column of data to show from the first sheet I am referencing it as follows:
INDIRECT("'Progress Matrix'!"&ADDRESS(MATCH($B$6, 'Progress Matrix'!$A:$A, 0)+1,
MATCH(C$6, 'Progress Matrix'!$1:$1, 0))&":"&ADDRESS(300, MATCH(C$6, 'Progress Matrix'!$1:$1, 0))))
(However this formula no longer seems to work as I think I changed something).
I've tried to incorporate
SUBTOTAL(3,OFFSET(A2,ROW(A2:A100)-ROW(A2),0))
to only show filtered results but with no success.

I am concatenating some cells into an array. The amount fields should always have just 2 rounded digits following the decimal. What should change in the following VBA code to achieve that result?
Currently Cells(r, 6) & Cells(r, 7) could have these values:
1.5
24.78945678
45.2341
What I want is rounded values to 2 decimals:
1.50
24.79
45.23

I'm trying to create a dynamic array so that when a user enters the first sheet name via an input box, excel will know to select the other sheets with ending (2), (3), (4) etc.
Currently this code works only if there are 4 sheets present (as I set this way), anything lower/higher is out of range.
How do I make it so that it will select sheets if there are less than 4 sheets present?
I tried nesting, but I pretty sure this array needs redimming or something. Is ubound a better option?

I am using Excel 2013 on Windows 7. In the above example columns A & B is the given list to process, and Columns C & D contain the result I am trying to achieve. The major part of this that I am having trouble on combining, separating them with commas in another cell, and ignoring a duplicate value. You can see bill has two red values, but I only need it displayed once in column D.
Two part question:
1) I'm relatively new to arrays, but what I need to do is generate a list of file names and the sheets within each one. I would like to use an array for this, but since I don't have much experience.... well....that's why I'm here. Can someone point me in the right direction?
2) And the second part of this.... I was planning on using the FileSystemObject to determine the files in a selected folder and loop through that list of files, opening each one and harvesting the required info (file name and all sheet names). Should I use the FSO or is there something built into Excel that might be better (and also limit the number of dependencies for this little "project" of mine).
in C a string is nothing more than an Array of characters ending with a null character.
in VBA this does not seem to be the case.I am trying to use the BlowFish code from David Midkiff for some encryption, however the code sometimes fails:
When encrypting a string a string of a specific length should be returned. however sometimes one of the characters of the encrypted string is a null character, and the returned encrypted string (with a embedded null character) is causing me problems. I want to check for the null character and if present redo the encryption. But how do I check for the presence of this null character in a unicode (double-byte) string?
Checking with Len(encrypted) gives the correct length (!) but trying to move each (unicode)character into an array fails when using the Mid() function past the null character in the string.
Now I can use
byteArray() = StrConv(unicodetext,vbFromUnicode)
to get the lower byte of each character into an array easily, but how do I do this for both bytes of the unicode characters?
Using an integer array does not work other than through
intArray(j) = CInt(AscW(Mid(Outp, j, 1)))
which fails on the nullstring in my encrypted text.
I have tried with variants but so far no luck. I thought if the string was entered into a variant then I could also address the variant as an array of bytes, but that does not seem to be accepted by VBA.
I am trying to populate many arrays with the same code using something like this. For this test, assume the following data in A1.

Code:
Sub populate()
Dim firstArr(5), secondArr(5), thirdArr(5), fourthArr(5), fifthArr(5) As Integer
Dim r, c, num As Integer

The above code does not work of course and falls over. I am unsure whether I should try and concatenate with something like this eg "" & arrName(i) = Cells (r,c) or go down a different route.
I need to export this to Xcelsius which doesn't support any macros/vba. Btw I can;'t use Row() in xcelsius too.

I have a class module with several private variables, including one that is an array of a user-defined type. I am trying to set the values of a single element of this array with "Property Let ..." from a string array:
View 4 Replies View RelatedSay I have 3 columns of data: A1:C10 and I want to run a Match() function on them all together to see if I get a match any one those cells, say the value of have in X1.
Since, Match only allows a One-Column lookup array.. is there a way to "concatenate" or "append" the 3 columns together within a formula so now I would be looking to Match in an array that is 1 column * 30 rows?
Basically want to convert =Match(X1,A1:C10,0) to =Match(X1,A1:A30,0) without moving around the raw data in the sheet.
And I want to avoid doing an AND or OR formula that uses 3 separate MATCH() for each column.
I have a hunch that the MMULT or MMULT/TRANSPOSE functions are involved, but can't seem to get it right.
I'm only starting to get to grips with arrays. I have what I consider to be a lot of data that I need to 'cut' into separate workbooks. I have written some code that does this by simply looping through each line, 250k+, checking against a variable and copying the row into a separate sheet. This took longer than it would have doing it manually. It was suggested to me that I use arrays to speed up the process. I have managed to store the test data into an array but am struggling to find a way to loop through and pull out an entire 'row' from the array based on a variable. I have looked for 2 days in various places to find some way to loop through the data held in the array, but to no avail.
That code will appear here from about 8am GMT tomorrow. I know that once I've cracked this I'm on the road to some very significant time saving and comprehensive report writing.
I want to pass an array to Offset in the "Height" parameter, without having to type the array.
{=MAX(SUBTOTAL(9,(OFFSET(A1,ROW(1:5),,{1,2,3,4,5}))))}
I can't seem to figure out how to build the {1,2,3,4,5}. I've tried another ROW(1:5) and have tried nesting that like N(ROW(1:5)) but nothing works.
How I can get the {1,2,3,4,5} without having to type it out (so that I can expand this to a larger list)??
I am trying to filter an array (the longer one) using the shorter array as the criteria. I am currently doing this using the following method
IF(LOOKUP(lookup cell, array)=lookupcell, lookupcell, "FALSE")
I then copy and paste 'values' and filter out the 'false' to get my final result.
This has worked in the past, but for some reason that I simply can't figure out, the formula isnt working! I've attached the example, and I've highlighted a number in blue (cell E522 and C103), (that should be being found in the 'LOOKUP' function) but is returning a "FALSE". I have looked over the code and simply can't figure out why Excel isn't returning the right value.
This is obviously happening for a quite a few of my numbers, as my filter result is returning an array that is about 1500 shorter than it should be. I have highlighted E522 as the 'example cell' to look at.
wondering is there a VBA equivalent of --() in excel that turns trues and falses to 1's and 0's?
