So i am trying to create a simple string, the code is pretty simple
Sub Macro1()
Dim yr As Variant
Dim site As Variant
yr = Array("2013", "2014")
site = Array("SHR", "SHW", "SHH")
q = 0
a = 0
Range("D3").Formula = "\\shared\Export\STA30\" & site(q) & "\" & Year(a) & "\XL\"
End Sub
pretty basic, and it works, but the output is:
\\shared\Export\STA30\SHR\1899\XL\
I'm presuming something has happened to my excel settings? I have used arrays like this in the past and have never encountered this problem. Does anyone know why this might be happening?
You have to use yr(a) insted of Year(a).
Year(int) return the converted int into year.
You have declared an array as yr and when you are printing in the output string you are using year(a).
Just change the year(a) to yr(a) and you would get the desired output.

I would like to convert a range of numbers (and single digits) from a number-only format to alpha-numeric format. Entire statement is in a single, excel cell and would like the converted version to be in a neighboring cell.
As an example:
Assuming 1-24=B1-B24
Assuming 25-48=C1-C24
INPUT—
screen 1-3,5,7-9,11-30,32-37,39-40,41,44-46
DESIRED OUTPUT (all acceptable)
screen B1-B3,B5,B7-B9,B11-C6,C8-C13,C15-C16,C17,C20-C22
OR
screen B1-B3,B5,B7-B9,B11-B24,C1-C6,C8-C13,C15-C16,C17,C20-C22
OR
screen B1-B3,B5,B7-B9,B11-B24
screen C1-C6,C8-C13,C15-C16,C17,C20-C22
Using excel functions is proving quite cumbersome so excel macro would be better. I've looked for examples of requested conversion but haven't found anything.
Any help is greatly appreciated.
Cheers,

Hey here is a solution that i tested out. Not sure if "screen" needs to be in the string or not. Let me know and I will tweak it if that's the case.
Its a user defined function. So drop this vba in a module and then go to a worksheet and type in "=AlphaConvert(" + the cell reference.
Assumption here is that only one cell will be referenced at a time.
Last this could easily be converted to a sub routine and probably run a bit faster than the function.
Public Function AlphaConvert(TargetCell As Range)
Dim v As Long
Dim vArr() As String
Dim i As Long
Dim iArr() As String
Dim a As String
vArr = Split(TargetCell.Value, ",")
For v = LBound(vArr) To UBound(vArr)
If InStr(vArr(v), "-") > 0 Then
iArr = Split(vArr(v), "-")
For i = LBound(iArr) To UBound(iArr)
If i = LBound(iArr) Then
a = AlphaCode(iArr(i))
Else
a = a & "-" & AlphaCode(iArr(i))
End If
Next i
vArr(v) = a
Else
vArr(v) = AlphaCode(vArr(v))
End If
If v = LBound(vArr) Then
AlphaConvert = vArr(v)
Else
AlphaConvert = AlphaConvert & "," & vArr(v)
End If
Next v
End Function
Private Function AlphaCode(Nbr As Variant)
Select Case Nbr
Case 1 To 24
AlphaCode = "B" & Nbr
Case Else
AlphaCode = "C" & Nbr - 24
End Select
End Function
I have this code where ttlMtrs is an integer < 7000
diffFormula = "=1-(" & ttlMtrs & "/7000)*1200"
Debug.Print diffForumla
I am trying to build a string that will evaluate once printed to a cell in excel.
When I Debug.print to check the string I only get blank lines. One time I got long string of garbage characters.
I am trying to figure out what I am misunderstanding in building this string. Any ideas are appreciated.
you have mispelled the variable name in the debug statement
Debug.Print diffForumla
should be
Debug.Print diffFormula
note the changed position of the u
Public Sub Test()
Dim ttlMtrs As String
Dim diffFormula As String
diffFormula = "=1-(" & ttlMtrs & "/7000)*1200)"
Debug.Print diffFormula
End Sub
This should be the result:
=1-(/7000)*1200)
I am writing VBA code for an Excel workbook. I would like to be able to open a connection with an Access database, and then import a txt file (pipe delimited) and create a new table in the database from this txt file. I have searched everywhere but to no avail. I have only been able to find VBA code that will accomplish this from within Access itself, rather than from Excel. Please help! Thank you
Google "Open access database from excel VBA" and you'll find lots of resources. Here's the general idea though:
Dim db As Access.Application
Public Sub OpenDB()
Set db = New Access.Application
db.OpenCurrentDatabase "C:\My Documents\db2.mdb"
db.Application.Visible = True
End Sub
You can also use a data access technology like ODBC or ADODB. I'd look into those if you're planning more extensive functionality. Good luck!
I had to do this exact same problem. You have a large problem presented in a small question here, but here is my solution to the hardest hurdle. You first parse each line of the text file into an array:
Function ParseLineEntry(LineEntry As String) As Variant
'Take a text file string and parse it into individual elements in an array.
Dim NumFields As Integer, LastFieldStart As Integer
Dim LineFieldArray() As Variant
Dim i As Long, j As Long
'Determine how many delimitations there are. My data always had the format
'data1|data2|data3|...|dataN|, so there was always at least one field.
NumFields = 0
For I = 1 To Len(LineEntry)
If Mid(LineEntry, i, 1) = "|" Then NumFields = NumFields + 1
Next i
ReDim LineFieldArray(1 To NumFields)
'Parse out each element from the string and assign it into the appropriate array value
LastFieldStart = 1
For i = 1 to NumFields
For j = LastFieldStart To Len(LineEntry)
If Mid(LineEntry, j , 1) = "|" Then
LineFieldArray(i) = Mid(LineEntry, LastFieldStart, j - LastFieldStart)
LastFieldStart = j + 1
Exit For
End If
Next j
Next i
ParseLineEntry = LineFieldArray
End Function
You then use another routine to add the connection in (I am using ADODB). My format for entries was TableName|Field1Value|Field2Value|...|FieldNValue|:
Dim InsertDataCommand as String
'LineArray = array populated by ParseLineEntry
InsertDataCommand = "INSERT INTO " & LineArray(1) & " VALUES ("
For i = 2 To UBound(LineArray)
If i = UBound(LineArray) Then
InsertDataCommand = InsertDataCommand & "'" & LineArray(i) & "'" & ")"
Else
InsertDataCommand = InsertDataCommand & LineArray(i) & ", "
End If
Next i
Just keep in mind that you will have to build some case handling into this. For example, if you have an empty value (e.g. Val1|Val2||Val4) and it is a string, you can enter "" which will already be in the ParseLineEntry array. However, if you are entering this into a number column it will fail on you, you have to insert "Null" instead inside the string. Also, if you are adding any strings with an apostrophe, you will have to change it to a ''. In sum, I had to go through my lines character by character to find these issues, but the concept is demonstrated.
I built the table programmatically too using the same parsing function, but of this .csv format: TableName|Field1Name|Field1Type|Field1Size|...|.
Again, this is a big problem you are tackling, but I hope this answer helps you with the less straight forward parts.
I'm learning for loop and I cannot get this problem fixed.
The problems are in the following codes.
dim rt as integer = 2
dim i As Integer = 0
dim currentpg as string = "http://homepg.com/"
For i = 0 To rt
currentpg = currentpg & "?pg=" & i
messagebox.show(currentpg)
next
'I hoped to get the following results
http://homepg.com/?pg=0
http://homepg.com/?pg=1
http://homepg.com/?pg=2
'but instead I'm getting this
http://homepg.com/?pg=0
http://homepg.com/?pg=0?pg=0
http://homepg.com/?pg=0?pg=0?pg=0
Please help me
Thank you.
You probably need something like this:
Dim basepg as string = "http://homepg.com/"
For i = 0 To rt
Dim currentpg As String = basepg & "?pg=" & i
messagebox.show(currentpg)
Next
Although a proper approach would be to accumulate results into a List(Of String), and then display in a messagebox once (or a textbox/file, if too many results). You don't want to bug user for every URL (what if there are 100 of them?). They would get tired of clicking OK.
First of all, you went wrong while copying the output of the buggy code. Here is the real one.
http://homepg.com/?pg=0
http://homepg.com/?pg=0?pg=1
http://homepg.com/?pg=0?pg=1?pg=2
It does not work because currentpg should be a constant but it is changed on each iteration.
Do not set, just get.
MessageBox.Show(currentpg & "?pg=" & i)
Or you can use another variable to make it more readable.
Dim newpg As String = currentpg & "?pg=" & i
MessageBox.Show(newpg)
Also, your code is inefficient. I suggest you to change it like this.
Dim iterations As Integer = 2
Dim prefix As String = "http://homepg.com/?pg="
For index As Integer = 0 To iterations
MessageBox.Show(prefix & index)
Next
before I start I want to point out that I tagged this question as VBA because I can't actually make a new tag for Winwrap and I've been told that Winwrap is pretty much the same as VBA.
I'm working on SPSS V19.0 and I'm trying to make a code that will help me identify and assign value labels to all values that don't have a label in the specified variable (or all variables).
The pseudo code below is for the version where it's a single variable (perhaps inputted by a text box or maybe sent via a custom dialogue in the SPSS Stats program (call the .sbs file from the syntax giving it the variable name).
Here is the Pseudo Code:
Sub Main(variable As String)
On Error GoTo bye
'Variable Declaration:
Dim i As Integer, intCount As Integer
Dim strValName As String, strVar As String, strCom As String
Dim varLabels As Variant 'This should be an array of all the value labels in the selected record
Dim objSpssApp As 'No idea what to put here, but I want to select the spss main window.
'Original Idea was to use two loops
'The first loop would fill an array with the value lables and use the index as the value and
'The second loop would check to see which values already had labels and then
'Would ask the user for a value label to apply to each value that didn't.
'loop 1
'For i = 0 To -1
'current = GetObject(variable.valuelist(i)) 'would use this to get the value
'Set varLabels(i) = current
'Next
'Loop for each number in the Value list.
strValName = InputBox("Please specify the variable.")
'Loop for each number in the Value list.
For i = 0 To varLabels-1
If IsEmpty (varLabels(i)) Then
'Find value and ask for the current value label
strVar = InputBox("Please insert Label for value "; varLabels(i);" :","Insert Value Label")
'Apply the response to the required number
strCom = "ADD VALUE LABELS " & strVar & Chr$(39) & intCount & Chr$(39) & Chr$(39) & strValName & Chr$(39) &" ."
'Then the piece of code to execute the Syntax
objSpssApp.ExecuteCommands(strCom, False)
End If
'intCount = intCount + 1 'increase the count so that it shows the correct number
'it's out of the loop so that even filled value labels are counted
'Perhaps this method would be better?
Next
Bye:
End Sub
This is in no way functioning code, it's just basically pseudo code for the process that I want to achieve I'm just looking for some help on it, if you could that would be magic.
Many thanks in advance

Winwrap and VBA are almost identical with differences that you can find in this post:
http://www.winwrap.com/web/basic/reference/?p=doc_tn0143_technote.htm
I haven't used winwrap, but I'll try to answer with my knowledge from VBA.
Dim varLabels As Variant
You can make an array out of this by saying for example
dim varLabels() as variant 'Dynamically declared array
dim varLabels(10) as variant 'Statically declared array
dim varLabels(1 to 10) as variant 'Array starting from 1 - which I mostly use
dim varLabels(1 to 10, 1 to 3) 'Multidimensional array
Dim objSpssApp As ?
"In theory", you can leave this as a variant type or even do
Dim objSpssApp
Without further declaration, which is basically the same - and it will work because a variant can be anything and will not generate an error. It is good custom though to declare you objects according to an explicit datatype in because the variant type is expensive in terms of memory. You should actually find out about the objects class name, but I cannot give you this. I guess that you should do something like:
set objSpssApp = new <Spss Window>
set objSpssApp = nothing 'In the end to release the object
Code:
'loop 1
For i = 0 To -1
current = GetObject(variable.valuelist(i)) 'would use this to get the value
Set varLabels(i) = current
Next
I don't exactly know why you want to count from 0 to -1 but perhaps it is irrelevant.
To fill an array, you can just do: varLabels(i) = i
The SET statement is used to set objects and you don't need to create an object to create an array. Also note that you did not declare half of the variables used here.
Code:
strVar = InputBox("Please insert Label for value "; varLabels(i);" :","Insert Value Label")
Note that the concatenation operator syntax is &.
This appears to be the same in WinWrap:
http://www.winwrap.com/web/basic/language/?p=doc_operators_oper.htm
But you know this, since you use it in your code.
Code:
'intCount = intCount + 1 'increase the count so that it shows the correct number
'it's out of the loop so that even filled value labels are counted
'Perhaps this method would be better?
I'm not sure if I understand this question, but in theory all loops are valid in any situation, it depends on your preference. For ... Next, Do ... Loop, While ... Wend, in the end they all do basically the same thing. intCount = intCount + 1 seems valid when using it in a loop.
Using Next (for ... next)
When using a counter, always use Next iCounter because it increments the counter.
I hope this reply may be of some use to you!
