VBA How To Read Cells Into Variables/array And Use In String

Apr 15, 2009

I made the formula work great, however I want to cut it down and simplify it and make it easier to manipulate... as opposed to having the filename written every so many times.. replace with a loop instead.... so:

Private Sub Weeklytestt_Click()
Dim varCurDate As String
If DateYesterday.Value = True Then Answer = "1"
If DateToday.Value = True Then Answer = "2"
If DateTyped.Value = True Then Answer = "3"

Select Case Answer
Case Is = "1"
varCurDate = Format(Date, "yyyymmdd")
varCurDate = varCurDate - 1
Case Is = "2"
varCurDate = Format(Date, "yyyymmdd")..........

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.

Populate Multiple Array Variables With Same Code By Dynamically Changing Array Name

I am trying to populate many arrays with the same code using something like this. For this test, assume the following data in A1.

1

9
10

11
12
13

16
17
18
19
20

21
22
23
24
25

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

[Code]....

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.

Read A Range Into An Array

Aug 10, 2007

In a Worksheet named "Input" and in Cells "B3:G?" I have 6 number groups. How can I ...

( 1 ) Put each of the 6 number groups into an array when I don't know what the last row number is.

( 2 ) Find the maximum value in any of those cells and attach it to a variable named MaxVal.

... so once I have done this I can then loop through each 6 number group and perform some calculations.

Read Entire Row Into An Array

Oct 9, 2007

I have a workbook with about 700 rows and about 40 records on each row. about 2-7 a day of these.
The procedure I currently use a loop for does 2 different things.

1 I collect only a few of the records from the line and place them in a separate sheet .I collect the individual data, identify the ID ( cell F) and then search for the corresponding ID on a nother sheet when I do find it I add the info to the sheet on the last + next row. (I sort later)

2 I collect the entire row and place it on yet a nother sheet.
The whole row has information that is categorised by the content of Cell A (name) so I copy the row and paste it into a separate sheet.

What I would idealy like to do is to copy the entire source sheet into an array once, and then copy the data into each target sheet using a loop to get each record from the array. Using only 1 loop to first read the separate data from the " array row" and place it into the first target sheet (procedure 1) and then switch the workbook and copy the whole "array row" into the target sheet there (procedure 2).

At the moment I read info on 1 row switch to the target sheet and place the information there, then I "copy" the row and switch to the next workbook and paste it there then I go back to the source and do the next row.

Obviously Im no programer and that was the best way of doing what I didnt know how to do better .

Is there a way that a whole row can be stored in an array and then 'copied' onto another row on a nother sheet without reading in the individual cells into separate elements. That would be the worse case scenario but a much faster way of doing what I curently have.

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.

How To Compare Two String Variables

Mar 27, 2014

I am trying to to work out how to compare two string variables that I can see with my eyes are clearly a match but getting the right syntax to convince VBA they are the same is my issue.The first example is:

Direct Credit 158824 BRANDON DONNA C/ Lak30

the second example is:

Direct Credit 158824 BRANDON DONNA C/ 30 Lake Vue Parade

but that still would not get a match that I can find code for.

i am chasing the "holy grail" in VBA and I will leave the records that do not exactly match to manual processing although i hate to give up that easily

Limitation On String Variables

Aug 2, 2006

I have recently come across a VBA macro, which reads from a text box within an excel input sheet, copy the text content, and send it via email. However, when the text content started to go beyond a certain number of characters, the text that comes out of the email, got truncated. I presumed this is something to do with the limitation to the string variables where the string " messagebody$ " which is used to read the text can only take up a certain bytes.

I was looking for VBA help, and somehow, it mentioned something called a variable-length string. Would that be a solution to my problem, or how is that used ?

Sheets("main").Select
ActiveSheet.Shapes("Rectangle 1").Select
messagebody = Selection.Characters.Text

....
email.Body = messagebody

Passing Array Variables In Functions?

Sep 15, 2012

What I am trying to do is to automatically build a "tree" diagram representing the links in a huge model which is dynamically configured. What I have a problem with is the following:

The tree consists of layers, I start off with the top layer and for each entry in the top layer I can add all its subsidiary layers and draw links between them, this uses a function which takes as its arguments the node name and its layer number (how far down the tree it is) and the number of items in that layer so far.

So I start at the first item in Layer 1 and there are as yet no layers below it. I start at the first one and add the first item in layer 2 then I kick the function off again and that adds the first item connected to item 1 in layer 2 in the layer below (3) starting at the first one, and so on. When I reach the bottom I go up one layer and add the second item in the bottom layer and so on. When I have added all the connctions to the first item in the next to bottom layer I go up one layer and add the second item connected to the first item in that layer and then add all the items connected to it and so on and so on.

In this way I build up the network exhaustively (to make things more complex more than one item in a layer may connect to the same item in the layer below).

I can do almost all that, the issue I am struggling with is I need to keep track of how many items there are in each layer (as some layer 1 items connect to 1, 2, 3 ...8 layer 2 items and so on). my idea is to keep a running total of these in an array LevelCount(1), LevelCount(2) etc. so when I add a new item to a layer I know where to put it. However I cant workout how to do this final step.

Currently I have a function that draws the nodes below a specified node this and takes the correct value from the array LevelCount(n) by passing Levelcount(n) (where n represents how far down the tree you are) into the function and the function then updates the value of LevelCount(n) (ByRef) so that next time I use it it is correct. That is fine but what I want to do is to is to call the same function from within itself when it adds each node which would make it work automatically - it would keep calling instances of the function until it reached bottom and then go back one step at a time to the top but I cant work out how to reference the right value in the array to pass into the second (and subsequent) instances of the function.

I don't think I can simply pass (n) into the function and in the body of the function set LevelCount(n) = LevelCount(n)+1

I also dont know ahead of time how many layers the model will have, nor can I tell which layer a node sits in as it depends on the links that are dynamically configured.

Beyond this a node can also be subsidiary to nodes in more than one level so it needs to sit at the lowest level - but I suspect if I can work out how to do the first bit i can do this too.

Variables To Contruct The Name Of The Active Array

Jun 24, 2008

I am trying to construct an indirect array reference as follows;

Dim A10 As Variant
Dim A11 As Variant
Dim A12 As Variant
For i = 0 To 2
String1 = "A" & (10 + i)
String1 = Cells(6, D1_CNum + i).Resize(2995, 1)
Next

But the above doesn't work, what would be the correct way of creating a reference to an Array using variables to contruct the name of the active Array?

I was hoping String1 would equal "A10", so that on the Cells command Array A10, A11 and A12 would be filled using the value of String1??

Create Array Of Variables And Sort

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 & ", "

Pass Array Variables Between Modules

Jun 8, 2007

I am trying to pass a public variable to another module in the same workbook. On Module1 I declare at the top

Public stores
Sub Main()
Dim stores(1 To 100, 1 To 10, 1 To 10)

Reader

...which then calls the procedure Reader in Module2

Sub Reader()
let x=1
let y=1
let z=1
let stores (x,y,z)=activecell.value

I've left out the portions of code that seem irrelevant. When the macro runs, I get a type mismatch error on the "let stores" line. If I move the code from Reader into the procedure Main, it works, so it seems to be an issue with passing the variable. I haven't used multiple modules very often so this is probably a very basic issue.

Range Names Created From String Variables

Aug 30, 2006

I work with data that varies in row numbers but is consisten in column width. I am trying to write code that will create a named range for the data but be flexible to expand or contract based on the amount of data that is pulled in. Below is the

Const lngLastPossRow As Long = 65536
Dim strDataRng As String
strDataRng = ActiveSheet.Name & "!R4C1:R" & Range("a" & lngLastPossRow).End(xlUp).Row & "C17"
Range(Selection, ActiveCell.SpecialCells(xlLastCell)).Select
ActiveWorkbook.Names.Add Name:=("Data"), RefersToR1C1:= _
strDataRng

While the result creates a named range called "Data" , it does not allow me to reference and data in any formulas ( sumif's, etc). Can someone tell me what I am missing. It appears to be returning the wrong data type (string as opposed to range values).

Copy Table Values To Array Variables And Use Them In Another Sheet?

Nov 20, 2012

I have a query about using Array Variables in excel VBA. I have a set of lookup tables and a main data table. The data table will be downloaded everyday. I need to replace the ID's in the main table with actual data from the Lookup tables.

e.g.
Main Data Table
Color Operator
005--325 005
004--326 004
003--327
001--328
002--322

Lookup Color
001 - Red
002 - Blue
003 - Green
004 - Violet
005 - White

Lookup Operator Table
323 - Operator 1
324 - Operator 2
325 - Operator 3
326 - Operator 4
327 - Operator 5
328 - Operator 6

I have a huge amount of data in the main table. So I can't use a lookup formula for automation. Rather I would like to use VBA to create array variables, scan and copy the lookup data into the array and replace the ID's in the main table.

Only that I am unable to achieve this using arrays. I am very basic in executing code related to Arrays.

File May Be Read-Only, Or You May Be Trying To Access A Read-Only Location
