I'm trying to pass an array of UDT from Excel to a C++ dll but I have no idea how. My UDT looks like this
Private Type Student
Age As Integer
Name As String
StudentID As String
End Type
And my dll function declaration..
Declare Function RegisterStudent Lib "SimpleDLL.dll" _
(arr() as Student) As String
.. which will return a unique Id in string
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 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.

View 2 Replies View RelatedI have an excel sheet, in that excel sheet is a command button, once clicked the command button creates a Word document.
Im trying to get my VBA script to bold certain text that will be in the word document. But all my attempts to bold certain cell contents have failed.
Im not getting any errors from the editor, its just not bolding certain text Ive told it too when the word document gets created.
I have included my script below (And Ive tried the following methods already)
1. ActiveCell.Font.Bold & "This Is Function One, This Text Will Appear Bold" & wks.Cells(ActiveCell.Row, 2) & _

I'm trying to pass an array from one userform to another. When I run the script, it says: "Constants, fixed-length strings, arrays, user-defined types, and Declare statements not allowed as Public members of an object module". It explains further that you cant make an array public. How can I pass my array between forms? It suggests using an varient that contains an array, I tried doing this, heres my
Dim multiAry(15) As Range
Public vmultiAry As Variant
'... and later:
vmultiAry = multiAry
'... and on the next userform:
Dim multiAry(15) As Range
multiAry = UserForm1.vmultiAry
With this, I get an error saying "Compiler error: Cant assign to array" with "multiAry =" selected. Am I doing it totally wrong? How can I pass an array between forms?
Okay, I made an epic fail on a previous post that i turned to Solved, a real error on my part of not fully testing before i posted Solved, basically i was so excited that i'd solved it myself, well partially.

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.

View 13 Replies View RelatedI have been searching for hours trying to find a solution to no avail. What I need to do is make sure that when I press a button on a form, the value in a combo-box should be populated as "text format" not as a number. The reason for this is that when my numbers start with a 0, the leading zero gets dropped and I can't run the rest of my code as the items don't match...
I have tried substituting the "Value" to "text" in : Me.cboItem.value and have tried for hours trying to name dim variables as a String and pass this into the cboItem...with no luck...

View 4 Replies View RelatedPassing 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,

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 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 RelatedI have list of strings to be searched in column A2 to A150 (A1 has column title). The array that needs to be searched is in B2 to AG1000 (B1 to AG1 has column title). I want each string in column A to be searched in the full array. If match is found the corresponding column title (B1 or C1 and so.) and cell address needs to written to a new result columns in AY and AZ. it should work for duplicates as well i.e. the string can be in all the columns of array from B to AG. and all of them needs to be written to result column.
View 9 Replies View RelatedI'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.
I have defined array say like this:
Dim myarray (1 to 5, 1 to 2)
Is possible to define something like this?
myarray (x, 1) as string
myarray (x, 2) as integer
x is anything between 1 to 5 .
Say I have a string, "a test array." I want to split this into an array where each character is an element. I was thinking something like
Dim MyArray As Variant
Dim MyString As String
MyString = "a test array"
MyArray = Split(MyString, "", Len(MyString), vbTextCompare)
But this doesn't work because Split() returns the entire string when the delimiter is a zero-length string.
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 = ""
I want to extract data from array string and then sum the values. For reference attaching the excel.
View 14 Replies View RelatedI set out this morning to count duplicates in an array and report a succinct list.... so I went down the route of using a collection with keys to do this.
1. Is there a better way? Else
2. split my collection values? I'm a bit stuck.
I have a series of values in a collection like this
: Item 2 : "Spam|01/07/2013|1" : Variant/String
: Item 4 : "Chips|01/07/2013|2" : Variant/String
So I have 3 key pieces of data delimited by a pipe sign -
Product | Date | Number of Occurrences
Item 4 is of interest to me because it occurs twice.
How I can turn those collection values into something I can work with, else another approach to sum rows in an array which are duplicates (if you only look at 2 columns).
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?
I have a function that will be used across 10K+ records at a time, so I was taking a look at optimizing it a bit. At the start of the routing I have a string with a 9 to 15 digit numeric value in it. I wanted to load each individual digit into a byte array. I started out using:
byVal = StrConv(sVal,vbFromUnicode)
But that actually loads the ASCII Character codes into the array not the digits themselves. From there I considered looping through the array applying CByte(Chr$(byVal(i))) but then I wondered if it would make more sense to just load the array with Mid$(sVal,i,1)... Does anyone have tested knowledge on which performs better? Is there an option C I have missed?
I have a string that I need to sort.
Below code works beautifully but doesn't sort numbers, any advice to get this to sort numbers as well?
