Excel VBA - Check If String Is In Array?

Sep 2, 2013

I have a test to see if a text string is in an array that mostly works, but sometimes fails and I don't understand why.

The routine calls a Function IsInArray which returns a True/False value depending on whether the search term is in the array.

Code:
Sub TestFilterArray()
MyArray = Array("a", "b", "c")
If IsInArray("a", MyArray) = False Then

[Code]....

In this case the first item in my array is "a - b" (note that this is a text string ), but for some reason because my test value is "a" the routine things it must be in the array.

Thus I am thinking that the ampersand and dash symbols are somehow confusing my routine.

How can I change my routine so that it correctly identifies which text strings are in my array?

VBA 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.

Excel 2007 :: Create String From Array?

Jul 23, 2012

I have this formula, ( which i found the basis of on a You tube video and Richard Scholar was accredited with improving the soloution)

=SUMPRODUCT(--ISNUMBER(F4:AH4)*10^{-29,-28,-27,-26,-25,-24,-23,-22,-21,-20,-19,-18,-17,-16,-15,-14,-13,-12,-11,-10,-9,-8,-7,-6,-5,-4,-3,-2,-1})

This forumla generates a number for each player, the higher the number the more inline they are to get a game

Problems are this works for the 29 weeks of this year but more weeks need added to the end of the year as we get there. Can i generate the array numbers from a formula and shorten.

This is a sample data ignore row 2( just a count of players) and data actually goes back to 6th Jan

Treating String As Array And Correct Array Format For Unicode Characters?

Jul 30, 2012

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.

Check Whether String Contains One Of Many Sub-strings

Nov 11, 2010

I'd like to write a formula that check if a string (contained in another cell - say A1) includes at least one occurrence of one of a set of 5 sub strings. If the substring is included then it should return which one.

For istance, say that the cell A1 = " The colour is BLACK" then I'd like a formula in cell B1 that check if any of the following strings is included in A1 (RED, GREEN, BLUE, BLACK, ORANGE) and that tells me which one.

How to do this with a one cell formula ?

Check If String Contains Only Digits

Apr 19, 2008

I'm working on a project where I need to prevent the user from entering non-digit string inputs. I've tried the using IsNumeric(MyString). but that doesn't prevent , + - signs to be entered. I also had to conditionally enable the input of a string with leading zeros like "01" so what I've ended up with is a rather messy looking' sub that handles this (don't know if forum rules allows me to show it here?). The problem is that I'm not a 100% sure that my sub fit to handle all eventualities so therefore my question is whether there is an easier, fool proof way to check my strings?

How To Check If Array Is Empty

Mar 1, 2014

Secondly, I am struggling to find a solution to something that in PHP, Java and javascript is painfully simple! That is - checking to see if an array contains no elements.

In PHP for example, you can do:

PHP Code:
$arr = array();echo empty($arr)."
";echo (sizeof($arr) == 0)."
"; 

This will produce the following output:

Code:
1
1

But ... I can't seem to find any equivalent of empty or sizeof in VBA.

Check If First 5 Digits Of String Are Numeric

May 23, 2007

I have some code where I need to check if the first five char are numbers and not letters.

I have in a column for example
12345-someone is here
23456-someone else is here
someone is here too

I need to get all of the ones that have 5 digits and not pull in the other into a new list.

I have tried Left(CPHierAll. Cells(CPHierAllRow, 1),5) which will get me the fist 5 char. and then i need to check to make sure that they are all numbers and not char.

if Left(CPHierAll.Cells(CPHierAllRow, 1),5) = "#####" then
But this does not bring anything in.

I also tried if CPHierAll.Cells(CPHierAllRow, 1),5) = "#####" then

I have 3 column that i am checking for different thinks the first two work just find and seperate out on the check but the last one with the numbers is being a pain.

Excel - UDF That Returns String Of Multiple String Objects / Possible To Color Font?

Sep 19, 2012

I have a udf that returns a string to the cell. The string is made up of multiple string "objects". What I am wondering is if I can set the font color of certain objects so that when the final string is built and returned, the font of those portions is set.

Ex. of simple idea (this is not actually my code, just a way to illustrate. I realize there is no point to this UDF):

VB:

Function StringReturn (Str1 As String, Str2 As String, Str3 As String) As String
StringReturn = Str1 & Str2 & Str3
End Function

Now what if I wanted Str1 and Str3 to be blue, and Str2 to be red for example. So that when the UDF calculates it would return: Str1Str2Str3

Array To Check User Input Match

Feb 22, 2007

This is what i want to do: SEE ATTACHEMENT

Write codes to pop up an InputBox to ask the user for a customer name.

The program uses the users input to check whether the name is on the list. If it is, display an msgbox saying that the customer name is on the list, and the corresponding cell will be indicated in boldface and in blue. Otherwise, an msgbox will be displayed saying that the customer name is not on the list.

Dim the customer list as an array (string var. type) and Dim Found as Boolean. You will need the If-Then construction and For-Next or Do-While/Until loop too). Create a button to run and another to restore the formatting to its original style.

This is what i did so far and still having problems with it:

Option Explicit

Sub customers()

Dim Arr()
Dim R As Integer
Dim C As Integer
Dim ReturnColumn As Boolean

Partial String Check In Cell Against Range For Return

Feb 15, 2010

I've posted this query before, not on this forum, but I don't think the replies I've had so far are going to do what I want. Initially I was looking for a formula, but the suggested pile of nested IFs won't work for the number of conditions. I saw a previous post on here for a VBA macro to search for a text value in a cell against the cell contents of a range and it seemed to do at least the first part of what I wanted. I attempted to manipulate it a little to test its applicability for my own nefarious purposes but for the life of me I can't get it working.

This is complicated by the fact that the actual data is commercially confidential, so I can't show you the actual file, but I can fake what I want with two simpler ones. I've attached them to this post. What I want is a fair bit more complex than the other post I found - I want to be able to compare a partial text string from a given cell in a range ('Check Value' in the attached TestBook2 ) against the strings in a range of cells ('Value 1' in TestBook1), and return the corresponding value from 'Test Value' to the corresponding adjacent cell to the tested 'Check Value', with an order of precedence, for example...

Testbook2 contains an entry in C5 of 'a, e, h, z, x, y'. Testbook1 shows that the return for a, b, c, or d is 'moo', for e, f, or g is 'steve' and for g through q is 'fred', all others being no returned value. Moo>steve>fred, so I want the corresponding 'moo, steve. fred or <blank>' cell to contain 'moo'. Conversely, C6 contains 't, u, z' and therefore shouldn't have a value in 'moo, steve, fred or <blank>'. C12 contains 'f, z, s, y, u' and C15 'i, x, z, s', and therefore should display 'steve' and 'fred' respectively.

If String Equals Value In Array?

I'm trying to verify if a cellvalue is available in an array. Here is the code:

First I tried to check if the cellval is in the array by returning a -1, 0 or 1:

Code:
If UBound(txt, cellval) = 0 Then
-> returns zero for value "h3", but also for value "3"
(where cellval the value in the cell is)
(with txt being the array containing "h3,r8,ty657", etc)

But I need only the If to be true when there is an exact match.

But this doesn't work because Split() returns the entire string when the delimiter is a zero-length string.

Sort String Array

Nov 18, 2006

I have a string (PreString) that gets its values from a procedure call (PreResult). The string consists of 4 values for each loop which I then split into the y array.

I then want to transpose the array to the worksheet for sorting.

I don't really get the transpose to work as I want to. I want every 4:th y to be printed on a new row (x). I don't really know how to use the Ubound function to get it right.

Should I make a 2 dimensional array instead ? If so, how is that made ?

Dim x As Integer, z As Integer
Dim var_Status As Integer
Dim var_Week As String
Dim var_HoursPerWeek As Integer
Dim PreString As String

i = var_StartWeekNr
j = var_RangeNumberOfWeeks
z = 0
x = 0
var_Status = 0
var_Week = ""
var_HoursPerWeek = 0
PreString = ""
