Public Array Not Clearing Between Runs
May 19, 2008I 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?
View 9 Replies View RelatedTreating String As Array And Correct Array Format For Unicode Characters?
Jul 30, 2012in 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.

Apr 7, 2009Say 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.
VBA To Output From Array Based On Variable In One Element Of Array
May 2, 2013I'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.
Passing Array To OFFSET - Array Height Parameter

{=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)??
Filter An Array (the Longer One) Using The Shorter Array As The Criteria
Aug 26, 2009I 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.

Creating Array From 2-dimensional Array
Nov 28, 2011I'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:
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.

Looking Up Row Array Data In Column Array
Jul 11, 2007On one sheet (KPI) I have either the values "x" or "" in the range A84:A89 to mark wheter to use the corresponding project in the range B84:B89. On the sheet X-ref I have the same project names in range T4:Y4 and a corresponding target value in T8:Y8
What I want is the sum (or average) of the marked-projects target-values. The result should end up in KPI!G31.
In other words I want
=sumif(A84:A89;"x";'X-ref'!T4:Y4)
but it doesn't work since the first range is an column-array and the second range is an row-array.
Return Array Elements From 2D Array
Feb 11, 2008I'm trying to use an array to carry out string function on a range of excel cells.
Here is the code I am using
Dim arrXl As Variant
arrXl = ws.Range("F1:F" & ws.Range("D1").End(xlDown).Row)
For i = LBound(arrXl) To UBound(arrXl)
MsgBox (LBound(arrXl))
'If 1st char is different from 3rd char then remove all of string after 1st char
If Left(arrXl(i), 1) <> Mid(arrXl(i), 3, 1) Then
arrXl(i) = Left(arrXl(i), 1)
End If
'If 1st char is different from 7th char then delete string after 5th char
If Left(arrXl(i), 1) <> Mid(arrXl(i), 7, 1) Then
arrXl(i) = Left(arrXl(i), 5)
End If
The lbound function returns the value of 1 as the lower bound, I do not have "Option base 1" set so I was expecting the lbound value to be 0. The first 2 cells in the F column are blank so this may have something to do with it, I am unsure if cells in excel can be null if they can be null one cell may be null and the other may be a zero length string but I am unsure about this.
The ubound function returns a value of 487.
The code breaks when I try to access an element in the array so it breaks on the line:
If Left(arrXl(i), 1) <> Mid(arrXl(i), 3, 1) Then
and returns the "Subscript out of range" error message.

View 3 Replies View RelatedVBA Find Partial String In Array And Output Found String Array Value?
Mar 31, 2014 I am trying to do a sort of index match thing using VBA. What I am attempting to do is to use the prefix of a long number and try to find that exact prefix in a string array, and output that string array value. So this is what I have so far as a test:
[Code].....
So I can match the text exactly so if I put PREFIXB in cell A1 in this example, i will get the msg box saying "YES", but if I make it PREFIXB1231k4j3jj1kj32cj, it will display "NO". I want to get it so that PREFIXB will be displayed in the cell that I put the formula in. So if A1 = "PREFIX1AAA100CF" and cell B1 = "=ABC(A1)", cell B1 will display "PREFIX1AAA".
Now the thing is that these prefixes can have different lengths, but will never encompass the exact prefix of another. So if I had a prefix of: PRE1AB, I won't have a prefix of PRE1A.

Coding An Array Within An Array
Aug 17, 2007I need to create an array within an array (or loop within a loop). First loop works fine as
x = 0
Dim DirArray(0 To 80) As String
Dim intI As Integer
For intI = 0 To 80
DirArray(intI) = Range("start").Offset(intI, 0).Value
Next
For x = 0 To 80
lob = DirArray(x)
Range("lob") = lob
Calculate
Sheets("WBB LOB Summary").Select
ActiveWindow.SelectedSheets.PrintOut Copies:=1, Collate:=True
Next
At the 'start' point (cell A1), first loop works downward through rows. Second loop (starting in cell B1) would work across columns in each row within the first loop. I will have to use a variable for 'y' (the across value) b/c the number of cells containing data can vary between 3 & 9, but I have a COUNTA in each row setup to use as the variable.
So spreadsheet data would look like this with X data being the 'start' cell:
X 1 2 3
Y 1 2 3 4 5 6
Z 1 2 3 4
I need to pickoff X1, X2, X3, Y1, etc, picking up every sub-category on the sheet.
