VBA Control Array
Aug 15, 2006
I have a form that launches when a user wants to confirm an order from a customer. It loads a drop-down combo box with our current customer list. When the user selects a customer, a checkbox array is loaded with the items that a customer has ordered. The checkboxes confirm (or un-confirm) that the order has been processed. Everything works fine up to this point. Let's say the user selects a customer, and this customer has 7 orders. 7 checkboxes appear on the form, either checked or unchecked.
The problem is:
when the user selects another customer from the drop down that only has 3 orders. The 3 checkboxes appear just fine, however, the balance of the previous customer (orders 4-7) also still show on the form. How do I remove the previous checkboxes from the form and prepare for a new recordset (or new checkbox array). I have tried to run backwards through the code that creates the array using Me.Controls.Remove instead of .Add, and this is just not working.

I need to make a vlookup which returns values for many 1000 material numbers. The values is located several other files. My problem is that i dont want to update all vlookups every time the other files (with my values) are getting updated.
e.g.
i want to have en cell A1: FileNameVersion1 and when someone updates the file the only thing i have to do is to change the name in cell A1 to FileNameVersion2.

Passing an array from a sub to another sometimes works, sometimes not. But when I call the same sub twice, it definately gets stuck at least at the second time. Seems as if I tend to lose some of my items of the array. And I cannot figure out why it happens, at what pace it happens or how I could stop this from happening.
1.Could it be that a control perishes as soon as it is set to 'ctrl.enabled=false'? 2.Or could it be that a declared array 'ary=array(tb1,cb1,frm1)' can not be handled without having had its items initialized with some lines of code, although the items visibly exist within the user form? 3. Can it be that a Sub 'remembers' the former values passed to it, if set to 'optional'?
However, I have added a cleared/minimized version of my userform as a file to this post, hoping that some of you out there might find the time to have a look at it.... I would really appreciate it. I have added the decisive parts of the macro below here, as well,
Private Sub UserForm_Initialize()
Dim elem As Variant
Dim wSht As Worksheet
Dim ctrl As Control
'set control arrays
'[...]
ctrlAllStep2 = Array(cbTimeOnly, cbIntensityOnly, cbAreaOnly) '[...]
ctrlAllStep3 = Array(tbIntensityTotal, tbIntensityBleached) '[...]
MsgBox "Two Controls exist now: 1." & ctrlAllStep2(0). name & ", 2. " & ctrlAllStep2(1).name, vbInformation, "Note: controls exist..."
'disable Controls in Step2 and in Step3....................

Is there any way in VBA to refer to a control in its own event procedure without referring to it by name/hard-coding?
It might be clearer to explain by a dummy code example:
[Code] ......
I'm seeking what I would need to replace Line1 with.

Within the ComboBox properties, is there anyway to control after "enter" his hit, you move to the right instead of down (similar to the edit under Tools/Options)?

I have created a userform within VBA which has a TreeView Control and a Spreadsheet control on it.
I have populated the TreeView control with data and what I want to be able to do is to drag the nodes off the TreeView control to the spreadsheet control.
I can drag onto a normal worksheet but not onto the spreadsheet control (the no drop mouse pointer keeps showing).

How do I determine which control the user is currently modifying on a multipage form (either changing, enterying or exiting the specific control). when I use "userform1.activecontrol" i get "multipage1" as the control name but I need the actual control on the specific active multipage. (also the .TABINDEX is for the multipage regardless of the on-page control) I use a generic data-field change SUBroutine so need the control name (and the TABINDEX) to provide my SELECT CASE. (so every fieldname_CHANGE calls the same SUB [with no parameters])

Has anyone out their ever seen an Calendar type of control totally built in an Excel vba UserForm?
My problem that I’ve tried to resolve for some time is utilizing some type of pop-up calendar to eliminate format issues in my published Excel forms. I have tried a number of calendar controls but all have to be registered on the local machine and this cannot be guarantied for every machine.
If someone could direct me to a vba UserForm that has this built in that might do the trick. Or is their another way to deal with this?

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.

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.

Say 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.

I have 2 macros: 1 controlled by a checkbox activex (PA_03) and the other a combobox (PA_03_rows) in a worksheet. I display the results from PA_03, and the user than then increase or decrease the number by using the combobox. But when I change the value (PA_03_rows.value = x) it causes the macro to jump to the macro.
I don't think it did initially, but it does now. According to another post, I saw it shouldn't do it! Is there something I'm just not seeing here?
Private Sub PA_03_Click()
Dim message, title, default, numberRows
Dim PA_rows As Integer
Application. ScreenUpdating = False
TakeFocusOnClick = False
Worksheets("sheet1").Select
ActiveSheet. Range("a15").Select
If PA_03.Value = True Then Goto Unhide:
If PA_03.Value = False Then Goto Hide:
Unhide:
message = "Enter the number of input rows required (1 to 50)"
title = "Non-Featured Standard Input"
default = "1"

Assume that I have in Sheet2 a list of CUSTOMIZED name.
[Code].....
Now in Sheet1, I have data in column A that has strings consist of the customized name.
For example
[Code] .....
What function should I use that could give me the result of the CUSTOMIZED name?
I was thinking of a formula i.e.
[Code] ......
Obviously, the above formula give me error. Even if it works, it'll not give me the customized name ...

I'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.

On 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.

I'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.

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.
