Problem with display currency in Listbox on MS-Access - vba

Any time the listbox in MS-Access receives data, it will automatically consider commas, semi-colons or other types of delimiters and separate the values into columns within the listbox.
Therefore, when I format the values to currency the comma it finds in $2,000 (for example) gets delimited to $2 (in column 1) and 000 (in column 2).
I did set column count to 4, so I see why it is doing that but there must be a different way...
I set the column count to 4 because I have 4 values that I want displayed in the list box.
List40.ColumnCount = 4
List40.AddItem (strProduct & ";" & mQty & ";" & format(uPricing,"Currency") & ";" & format(tPricing,"Currency"))
In summary I expect my list to look like this
+---------+----------+-----------+-----------+
| PRODUCT | QUANTITY | UNITPRICE | TOTALCOST |
+---------+----------+-----------+-----------+
| abc | 5 | $500.00 | $2,500.00 |
+---------+----------+-----------+-----------+
Instead I see:
+---------+----------+-----------+-----------+
| PRODUCT | QUANTITY | UNITPRICE | TOTALCOST |
+---------+----------+-----------+-----------+
| abc | 5 | $500.00 | $2 |
+---------+----------+-----------+-----------+

Enclose the value between double quotes (ASCII code 34):
.....& ";" & Chr(34) & format(tPricing,"Currency") & Chr(34))

Excel/VBA/Conditional Formatting: Dictionary of Dictionaries

I've got an Excel workbook that obtains data from an MS SQL database. One of the sheets is used to check the data against requirements and to highlight faults. In order to do that, I've got a requirements sheet where the requirement is in a named range; after updating the data I copy the conditional formatting of the table header to all data rows. That works pretty nicely so far. The problem comes when I have more than one set of requirements:
An (agreeably silly) example could be car racing, where requirements may exist for driver's license and min/max horsepower. When looking at the example, please imagine there are a few thousand rows and 71 columns presently...
+-----+--------+----------------+------------+---------+
| Car | Race | RequirementSet | Horsepower | License |
+-----+--------+----------------+------------+---------+
| 1 | Monaco | 2 | 200 | A |
+-----+--------+----------------+------------+---------+
| 2 | Monaco | 2 | 400 | B |
+-----+--------+----------------+------------+---------+
| 3 | Japan | 3 | 200 | C |
+-----+--------+----------------+------------+---------+
| 4 | Japan | 3 | 300 | A |
+-----+--------+----------------+------------+---------+
| 5 | Japan | 3 | 350 | B |
+-----+--------+----------------+------------+---------+
| 6 | Mexico | 1 | 200 | A |
+-----+--------+----------------+------------+---------+
The individual data now needs to be checked against the requirements set in another sheet:
+-------------+---------------+---------------+---------+
| Requirement | MinHorsepower | MaxHorsepower | License |
+-------------+---------------+---------------+---------+
| 1 | 200 | 250 | A |
+-------------+---------------+---------------+---------+
| 2 | 250 | 500 | B |
+-------------+---------------+---------------+---------+
| 3 | 250 | 400 | A |
+-------------+---------------+---------------+---------+
In order to relate back to my present situation, I am only looking at either the Monaco, Japan or Mexico Race, and there is only 1 record in the requirements sheet, where the value in e.g. Cell B2 is always the MinHorsepower and the value in C2 is always the MaxHorsepower. So these cells are a named range that I can access in my data sheet.
Now however I would like to obtain all races at once, and refer conditional formatting formulas to the particular requirement.
Focussing on "Horsepower" in Monaco (requirement set 2), I can now find out that the min Horsepower is 250 and the max is 500 - so I will colour that column for car 1 as red and for car 2 as green.
The formula is programatically copied from the header row (the first conditional format rule is if row(D1) = 1 then do nothing)
I can't decide what the best approach to the problem is. Ideally, the formula is readable, something like `AND(D2 >= MinHorsepower; D2 <= MaxHorsepower) - I cannot imagine it to be maintainable if I had to use Vlookup combined with Indirect and Match to match a column header in requirements for that particular requirement - especially when it comes to combining criteria like in the HP example with min and max above.
I am wondering if I should read the requirements table into a dictionary or something in VBA, and then use a function like
public function check(requirementId as int, requirement$)
which then in Excel I could use like =D2 >= check(c2, "MinHorsepower")
Playing around with this a little bit it appears to be pretty slow as opposed to the previous system where I could only have one requirement. It would be fantastic if you could help me out with a fresh approach to this problem. I'll update this question as I go along; I'm not sure if I managed to illustrate the example really well but the actual data wouldn't mean anything to you.
In any case, thanks for hanging in until here!
Edit 29 October 2016
I have found a solution as basis for mine. Using the following code I can add my whole requirements table to a dictionary, and access the requirement.
Using a class clsRangeToDictionary (based on Tim Williams clsMatrix)
Option Explicit
Private m_array As Variant
Private dictRows As Object
Private dictColumns As Object
Public Sub Init(vArray As Variant)
Dim i As Long
Set dictRows = CreateObject("Scripting.Dictionary")
Set dictColumns = CreateObject("Scripting.Dictionary")
'add the row keys and positions. Skip the first row as it contains the column key
For i = LBound(vArray, 1) + 1 To UBound(vArray, 1)
dictRows.Add vArray(i, 1), i
Next i
'add the column keys and positions, skipping the first column
For i = LBound(vArray, 2) + 1 To UBound(vArray, 2)
dictColumns.Add vArray(1, i), i
Next i
' store the array for future use
m_array = vArray
End Sub
Public Function GetValue(rowKey, colKey) As Variant
If dictRows.Exists(rowKey) And dictColumns.Exists(colKey) Then
GetValue = m_array(dictRows(rowKey), dictColumns(colKey))
Else
Err.Raise 1000, "clsRangeToDictionary:GetValue", "The requested row key " & CStr(rowKey) & " or column Key " & CStr(colKey) & " does not exist"
End If
End Function
' return a zero-based array of RowKeys
Public Function RowKeys() As Variant
RowKeys = dictRows.Keys
End Function
' return a zero-based array of ColumnKeys
Public Function ColumnKeys() As Variant
ColumnKeys = dictColumns.Keys
End Function
I can now read the whole RequirementSet table into a dictionary and write a helper to obtain the particular requirement roughly so:
myDictionaryObject.GetValue(table1's RequirementSet, "MinHorsePower")
If someone could help me figure out how to put this into an answer giving the credit due to Tim Williams that'd be great.

Excel VBA - How to insert comma after each word in a column

I have a column that contains multiple word strings. Like this:
+---+-------------------------------+--------------+-------------------------------+--------------+-------------------------------+-------------------------------+
| | A | B | C | D | E | F |
+---+-------------------------------+--------------+-------------------------------+--------------+-------------------------------+-------------------------------+
| 1 | Early Summer Lawn Application | Service Call | Early Summer Lawn Application | Grub Control | Early Summer Lawn Application | Early Summer Lawn Application |
+---+-------------------------------+--------------+-------------------------------+--------------+-------------------------------+-------------------------------+
My question is how can I insert a comma after each word in the column, to end up with:
+---+-------------------------------+--------------+-------------------------------+--------------+-------------------------------+-------------------------------+
| | A | B | C | D | E | F |
+---+-------------------------------+--------------+-------------------------------+--------------+-------------------------------+-------------------------------+
| 1 | Early,Summer,Lawn,Application | Service,Call | Early,Summer,Lawn,Application | Grub,Control | Early,Summer,Lawn,Application | Early Summer Lawn Application |
+---+-------------------------------+--------------+-------------------------------+--------------+-------------------------------+-------------------------------+
Its ok to lose the space between the words and its ok if the results are in a different column, I just don't know how to insert the commas.
Won't a simple replace work here?
=replace(A1," ", ",")
replaces space with comma. The other function is
=substitute(A1, " ", ",")
also works, but substitute has another argument that might come in handy. It specifies which occurrence to substitute. For example, if you only wanted to replace the first blank space with comma but leave other blank spaces as is, then try this:
=substitute(A1, " ", ",", 1)
Bottom line, use replace if you know where to replace (position), and use substitute if you know what to replace (content). Either would work for a narrow class of problems as you discovered.
The following example erplaces programmatically all spaces with commas:
Sub example()
Dim s1 As String, s2 As String
Dim pos As Integer
s1 = ActiveSheet.ActiveCell.Value
s2 = ""
pos = InStr(1, s1, " ")
While (pos <> 0)
s2 = s2 & Mid(s1, 1, pos - 1) & ","
s1 = Mid(s1, pos + 1)
pos = InStr(1, s1, " ")
Wend
s2 = s2 & s1
ActiveSheet.ActiveCell.Value = s2
End Sub

make variable as field name sql using vb.net

msg = DS.Tables("t").Rows(0)(0).ToString()
MessageBox.Show(msg)
I got wrong answer with this code because the answer of this code is "2015" but I expect the answer to be "10". Can someone help me the proper code of this?
In PostgreSQL, your column name "2015" is interpreted as a literal value. So when you submit the query:
SELECT 2015 FROM tbl_coll_penalty ...
you simply get the value 2015 back.
In the SQL standard, a column identifier cannot start with a numeral (0..9). Check the documentation here. To have PostgreSQL interpret the string "2015" as a column name, you should double-quote it:
sql = "select """ & asd & """ from tbl_coll_penalty where month = 'february'"

Conditional Sum in Excel with Multiple Sheets

My data looks like this, it has 3 columns: Town Code, Ward Code and the corresponding Population of that Ward :
| Town | Ward | Population |

I am not able to write a code in vba that will be give me the sum of population for all Wards under a Town (ie total Population of a Town). Considerations:- I have a huge dataset. I have multiple sheets over which I have the same kind of data, with different Town ID's (also different number of Wards per Town).

Is there a way to perform a cross join or Cartesian product in excel?

At the moment, I cannot use a typical database so am using excel temporarily. Any ideas?
The
You have 3 dimensions here: dim1 (ABC), dim2 (123), dim3 (XYZ).
Here is how you make a cartesian product of 2 dimensions using standard Excel and no VBA:
1) Plot dim1 vertically and dim2 horizontally. Concatenate dimension members on the intersections:
2) Unpivoting data. Launch pivot table wizard using ALT-D-P (don't hold ALT, press it once). Pick "Multiple consolidation ranges" --> create a single page.. --> Select all cells (including headers!) and add it to the list, press next.
3) Plot the resulting values vertically and disassemble the concatenated strings
Voila, you've got the cross join. If you need another dimension added, repeat this algorithm again.
Cheers,
Constantine.
Here is a very easy way to generate the Cartesian product of an arbitrary number of lists using Pivot tables:
https://chandoo.org/wp/generate-all-combinations-from-two-lists-excel/
The example is for two lists, but it works for any number of tables and/or columns.
Before creating the Pivot table, you need to convert your value lists to tables.
Using VBA, you can. Here is a small example:
Sub SqlSelectExample()
'list elements in col C not present in col B
Dim con As ADODB.Connection
Dim rs As ADODB.Recordset
Set con = New ADODB.Connection
con.Open "Driver={Microsoft Excel Driver (*.xls)};" & _
"DriverId=790;" & _
"Dbq=" & ThisWorkbook.FullName & ";" & _
"DefaultDir=" & ThisWorkbook.FullName & ";ReadOnly=False;"
Set rs = New ADODB.Recordset
rs.Open "select ccc.test3 from [Sheet1$] ccc left join [Sheet1$] bbb on ccc.test3 = bbb.test2 where bbb.test2 is null ", _
con, adOpenStatic, adLockOptimistic
Range("g10").CopyFromRecordset rs '-> returns values without match
rs.MoveLast
Debug.Print rs.RecordCount 'get the # records
rs.Close
Set rs = Nothing
Set con = Nothing
End Sub
Here's a way using Excel formulas:

| 1 | | | |

Formula3: IF(ROW() >= 8 + (3*3*3), "", INDIRECT(ADDRESS(3 + MOD(FLOOR(ROW() - 8)/(1) , 3), 3)))
One* general formula to rule them all!
The result
The formula
MOD(CEILING.MATH([index]/PRODUCT([size of set 0]:[size of previous set]))-1,[size of current set])+1
This formula gives the index (ordered position) of each element in the set, where set i has a size of n_i. Thus if we have four sets the sizes would be [n_1,n_2,n_3,n_4].
Using that index one can just use the index function to pick whatever attribute from the set (imagine each set being a table with several columns one could use index([table of the set],[this result],[column number of attribute]).
Explanation
The two main components of the formula explained, the cycling component and the partitioning component.
Cycling component
=MOD([partitioning component]-1, [size of current set])+1
Cycles through all the possible values of the set.
The modulo function is required so the result will "go around" the size of the set, and never "out of bounds" of the possible values.
The -1 and +1 help us go from one-based numbering (our set indexes) to zero-based numbering (for the modulo operation).
Partitioning component
CEILING.MATH([index]/PRODUCT([size of set 0]:[size of previous set]):
Partitions the "cartesian index" in chunks giving each chunk an "name".
The "cartesian index" is just a numbering from 1 to the number of elements in the Cartesian Product (given by the product of the sizes of each set).
The "name" is just an increasing-by-chunk enumeration of the "cartesian index".
To have the same "name" for all indexes belonging to each chunk, we divide the "cartesian index" by the number of partitions and "ceil" it (kind of round up) the result.
The amount of partitions is the total size of the last cycle, since, for each previous result one requires to repeat it for each of this set's elements.
It so happens that the size of the previous result is the product of all the previous sets sizes (including the size of a set before the first so we can generalize, which we will call the "set 0" and will have a constant size of 1).
With screenshots
Set sizes
Prepared set sizes including the "Set0" one and the size of the Cartesian Product.
Here, the sizes of sets are:
"Set0": 1 in cell B2
"Set1": 2 in cell C2
"Set2": 5 in cell D2
"Set3": 3 in cell E2
Thus the size of the Cartesian product is 30 (2*5*3) in cell A2.
Results
Table structure _tbl_CartesianProduct with the following columns and their formulas:
Results:
Cartesian Index: =IF(ROW()-ROW(_tbl_CartesianProduct[[#Headers];[Cartesian Index]])<=$A$2;ROW()-ROW(_tbl_CartesianProduct[[#Headers];[Cartesian Index]]);NA())
concatenation: =TEXTJOIN("-";TRUE;_tbl_CartesianProduct[#[Index S1]:[Index S3]])
Index S1: =MOD(CEILING.MATH([#[Cartesian Index]]/PRODUCT($B$2:B$2))-1;C$2)+1
Index S2: =MOD(CEILING.MATH([#[Cartesian Index]]/PRODUCT($B$2:C$2))-1;D$2)+1
Index S3: =MOD(CEILING.MATH([#[Cartesian Index]]/PRODUCT($B$2:D$2))-1;E$2)+1
step "size of previous partition":
Size prev part S1: =PRODUCT($B$2:B$2)
Size prev part S2: =PRODUCT($B$2:C$2)
Size prev part S3: =PRODUCT($B$2:D$2)
step "Chunk name":
Chunk S1: =CEILING.MATH([#[Cartesian Index]]/[#[Size prev part S1]])
Chunk S2: =CEILING.MATH([#[Cartesian Index]]/[#[Size prev part S2]])
Chunk S3: =CEILING.MATH([#[Cartesian Index]]/[#[Size prev part S3]])
final step "Cycle through the set":
Cycle chunk in S1: =MOD([#[Chunk S1]]-1;C$2)+1
Cycle chunk in S2: =MOD([#[Chunk S2]]-1;D$2)+1
Cycle chunk in S3: =MOD([#[Chunk S3]]-1;E$2)+1
*: for the actual job of producing the Cartesian enumerations
A little bit code in PowerQuery could solve the problem:
let
Quelle = Excel.CurrentWorkbook(){[Name="tbl_Data"]}[Content],
AddColDim2 = Table.AddColumn(Quelle, "Dim2", each Quelle[Second_col]),
ExpandDim2 = Table.ExpandListColumn(AddColDim2, "Dim2"),
AddColDim3 = Table.AddColumn(ExpandDim2, "Dim3", each Quelle[Third_col]),
ExpandDim3 = Table.ExpandListColumn(AddColDim3, "Dim3"),
RemoveColumns = Table.SelectColumns(ExpandDim3,{"Dim1", "Dim2", "Dim3"})
in RemoveColumns
Try using a DAX CROSS JOIN. Read more at MSDN
You can use the expression CROSSJOIN(table1, table2) to create a cartesian product.
