I am trying to calculate a field in an Access 2010 query that takes the number in volumes and either uses the default URL (for values of 1) or loops as many times as there are volumes to create a series of URLs (it's OK if they're all together, it will be text output in a report in the end).
If 1 volume, http://blah.com/1. If 2 volumes, http://blah.com/2/vol1, http://blah.com/2/vol2 .
I was thinking of something like this:
=IIf([volumes]="1",[URL],for i=1 to [volumes] output [URL] & "/vol[i], " next)
but I can't figure out if I need a variable for volumes or how to assign it or how to generated the output. Any advice on how to go about this would be greatly appreciated.
URL Item volumes
http://blah.com/1 Book1 1
http://blah.com/2 Book2 2
http://blah.com/3 Book3 10
Thanks,
Sandy
A simple loop will do:
Public Function PrintUrlVol(ByVal Url As String, ByVal Volume As Integer) As String
Dim UrlList As String
Dim Index As Integer
If Volume = 1 Then
UrlList = Url
ElseIf Volume > 1 Then
For Index = 1 To Volume
If UrlList <> "" Then
UrlList = UrlList & ", "
End If
UrlList = UrlList & Url & "/vol" & CStr(Index)
Next
End If
PrintUrlVol = UrlList
End Function

I have a csv as shown in the image below. The data is a set of separate tables, separated by a blank line, that I require to be in separate csv files.
After importing to R, I'd like to split the data into the various separate tables, and then write these tables to separate csv files. I had the idea of using some kind of string detect, as a 'new' table is signified by the first instance of 'Area' in the first column. Any ideas of how to approach the code for this in R? There are a bunch of tables and doing this manually isn't advisable.
There's a truncation problem too it seems, as the tables will be required to have a differing amounts of columns, however I don't expect that getting rid of NULL or NA data should be too difficult with this.
Thanks for any help.
I don't think R is the right tool for this kind of thing. You should always try to use the right tool based on the task. Since you have Excel installed run this VBA script. That will do what you want.

You should take each different table to the uppermost part. All in all, you have 5 tables with different dimensions (Table1: 11x13; Table2: 11x9; Table3: 3x12; Table4: 10x5; Table5: 6x7). Take them side-by-side in the above (A1:M11; N1:V11 etc.). The headings of tables would be in 1st row.
library(readxl)
# Use the path returned from getwd() function that is R's working directory
df <- as.data.frame(read_excel("C://Users//User//Documents//Revolution//Your.xlsx"))
Then, you can handle these 5 tables as:
Table1 <- df[,1:13]
Table2 <- df[,14:22]
Table3 <- df[1:3,23:34]
Table4 <- df[1:10,35:39]
Table5 <- df[1:6,40:46]
By caring dimensions stemmed from different row numbers in the assignmets, you do not face any NA or NULL value in Table1...Table5.
I have a data set with several hundred rows. Most rows have complete information, but in some cases two rows share the same key while some attributes are repeated, others are not. Here is an example:
Key Campaign Message Stat1 Stat2 Stat3 Stat4
123 Fun yay 1 2
123 temp yay 3 4
Intended result
123 Fun yay 1 2 3 4
Issues:
Needs to search the entire dataframe of hundreds of records, most of which are not duplicates. Ignore the non-duplicates
Has to specify that when combining rows to accept the Campaign data that is NOT "temp"
All other columns where data matches is ok
Columns where one value is null will result in the non-null value being used in the new record
I am open to solutions in R, SQL or excel (vba)
Appreciate any help!
Turned out to be a bit more involved than I thought, but here it is. I am using a collection to merge duplicate keys. Change IGNORE_TEMP constant to include or exclude temp records.

Dim key As String
Dim arr() As Variant
Dim v As Variant
Dim vv As Variant
Dim i As Long
Dim isChanged As Boolean
For Each rw In data.Rows
key = rw.Cells(1) ' the first column is key
If IGNORE_TEMP And rw.Cells(2) = "temp" Then
DoEvents ' pass temp if enabled
Else
If Not contains(cMerged, key) Then
' if this is new key, just add it
arr = rw
cMerged.Add arr, key
Else
' if key exists - extract, merge nulls and replace
arr = cMerged(key)
' iterate through cells in current and stored rows,
' identify blanks and merge data if current is empty
i = 1
isChanged = False
For Each c In rw.Cells
If Len(Trim(arr(1, i))) = 0 And Len(Trim(c)) > 0 Then
arr(1, i) = c
isChanged = True
End If
i = i + 1
Next
' collections in vba are immutable, so if temp row
' was changed, replace it in collection
If isChanged Then
cMerged.Remove key
cMerged.Add arr, key
End If
End If
End If
Next
' output the result
Dim rn As Long: rn = 1 ' output row
Dim numRows As Long
Dim numCols As Long
With ActiveSheet.[a6] ' output start range
For Each v In cMerged
numRows = UBound(v, 1) - LBound(v, 1) + 1
numCols = UBound(v, 2) - LBound(v, 2) + 1
.Cells(rn, 1).Resize(numRows, numCols).Value = v

I am using a text box for input to my SQL query. Based on the input I create a certain query and display the data in a gridview.
However I wish to make an adjustment for my users.
They often make an input like PL26... However this is not a valid name in the database to search for. Therefore I want to CHECK their input, and alter it accordingly, so they don't have to think about it.
I happen to know that when they type PL26 the correct input would be PL000026 ... The entity to search for is always "PL" + 6 characters/numbers... so if they wrote PL155, the number/string I pass to the sql query should become PL + 000 + 155 = PL000155.
I hope someone can help me how to accomplish this. That is if it is possible?
My idea/Pseudo code would be something like
If tbInput.txt's FIRST 2 CHARS are PL, then check total length of string
if StringLength < 8 characters, then
if length = 2 then ADD 4 0' after PL...
if length = 3 then add 3 0's after PL...
if length = 3 then add 3 0's after PL..
etc
....
...
Here we go:
Private Sub Button21_Click(sender As System.Object, e As System.EventArgs) Handles Button21.Click
Debug.Print(formatCode("PL1"))
Debug.Print(formatCode("PL"))
Debug.Print(formatCode("PL01"))
Debug.Print(formatCode("PL155"))
End Sub
Private Function formatCode(userInput As String) As String
Dim returnVal As String
If userInput.Length < 8 Then
returnVal = String.Concat(userInput.Substring(0, 2), userInput.Substring(2, userInput.Length - 2).PadLeft(6, "0"))
Else
returnVal = userInput
End If
Return returnVal
End Function
You may need to add some validation ensuring it starts with PL etc.
The following will work as long as there are no other non-numeric characters in between the PL and the numbers. You can always add it in your validation.
Dim newInput As String
If (input.StartsWith("PL")) Then
input = input.Remove(0, 2)
End If
' If this fails then it means the input was not valid
Dim numberPart = Convert.ToInt32(input)
newInput = "PL" + numberPart.ToString("D6")
Exctract a number by removing prefix "PL"
Parse to Integer
Use Custom Numeric Format Strings(zero placeholder) for adding zeros and prefix
Const PREFIX As String = "PL"
Dim exctractedNumber As Int32
If Int32.TryParse(tbInput.txt.Replace(PREFIX, String.Empty), exctractedNumber) = False Then
'Error nahdling
Exit Sub
End If
Dim finalFormat As String = String.Format("'{0}'000000", PREFIX)
Dim finalValue As String = exctractedNumber.ToString(finalFormat)
I would make use of the handy PadLeft method:
Dim input As String = "PL26"
Dim number As String = input.Substring(2, input.Length - 2)
If number.Length <> 6 Then
number = number.PadLeft(6, "0"C)
End If
MSDN String.PadLeft
I have one data table in VB page which contain bulk data.In that data table one column named as vType and values in that column is one of Pr defined values such as 'A','B','C','D' etc , which comes from one Datable.
Now I want count of each type at the end.
For ex : CountA = 20,CountB=25 and so on .
Till now I have compared Each value using If condition which is static
For each dr as dataRow in dsType.rows
If dr("vType") = 'A' Then
CountA += 1
ElseIf dr("vType") = 'B' Then
CountB +=1
Next dr
and this If condition will repeat depend upon no of types in that data table (at max 8 fix values) I want to do this in single if condition ( Dynamic if Possible) Can I Count these values and store the same into single varaible? appreciate for you prompt reply.
You can use Linq-To-DataSet and Enumerable.GroupBy + Enumerable.Count on each group:
Dim typeGroups = dsType.AsEnumerable().
GroupBy(Function(row) row.Field(Of String)("vType")).
Select(Function(g) New With{ .Type = g.Key, .Count = g.Count(), .TypeGroup = g })
Note that New With creates an anonymous type in VB.NET with custom properties. So like a class on-the-fly which you can use in the current method.
Now you can enumerate the query with For Each:
For Each typeGroup In typeGroups
Console.WriteLine("Type:{0} Count:{1}", typeGroup.Type, typeGroup.Count)
Next
I cannot use Linq, i need to use simple vb only
Then use a Dictionary:
Dim typeCounts = New Dictionary(Of String, Integer)
For Each row As DataRow In dsType.Rows
Dim type = row.Field(Of String)("vType")
If (typeCounts.ContainsKey(type)) Then
typeCounts(type) += 1
Else
typeCounts.Add(type, 1)
End If
Next
Now you have a dictionary where the key is the type and the value is the count of the rows with this type.
why not getting the pretend result from the db itself?
Like so:
select count(*), vType
from someTable
group by vType
Not so sure about your question .. but this is what I've considered ..
You can make it as Sub ..
Sub AssignIncr(ByVal ds as DataSet,byval sFi as String,byval sCrit as String,ByRef Counter as Integer)
For each dr as dataRow in ds.rows
If dr(sFi) = sCrit Then Counter += 1
Next dr
End Sub
So you may use it by ..
AssignIncr(dsType,"vType","A",CountA)
I am copying a question and answer from elsewhere as it partly goes into what I need but not completely.
In ASP classic, is there a way to count the number of times a string appears in an array of strings and output them based on string and occurrence count?
For example if I have an array which contains the following :
hello
happy
hello
hello
testing
hello
test
happy
The output would be:
hello 4
happy 2
test 1
testing 1
The answer that was given was this:
I'm assuming the language is VBScript (since that's what most people use with classic ASP).
You can use a Dictionary object to keep track of the individual counts:
Function CountValues(pArray)
Dim i, item
Dim dictCounts
Set dictCounts = Server.CreateObject("Scripting.Dictionary")
For i = LBound(pArray) To UBound(pArray)
item = pArray(i)
If Not dictCounts.Exists(item) Then
dictCounts.Add item, 0
End If
dictCounts.Item(item) = dictCounts.Item(item) + 1
Next
Set CountValues = dictCounts
End Function
This is great but I can't work out how to grab the top 2 most used words, display them and be able to put them in their own variable for use elsewhere.
Can anyone help with this?
You can loop through the dictionary object using this method. Inside that loop keep track of the top two keys and their counts in either a new array or two new variables.
You can't sort a Dictionary object in VBScript, so you have to use something else.
My advice is using a disconnected Recordset object to hold the items and their occurrences. Such object natively support sorting and it's pretty easy to use. To achieve this have such function instead:
Function CountValues_Recordset(pArray)
Dim i, item
Dim oRS
Const adVarChar = 200
Const adInteger = 3
Set oRS = CreateObject("ADODB.Recordset")
oRS.Fields.Append "Item", adVarChar, 255
oRS.Fields.Append "Occurrences", adInteger, 255
oRS.Open
For i = LBound(pArray) To UBound(pArray)
item = pArray(i)
oRS.Filter = "Item='" & Replace(item, "'", "''") & "'"
If (oRS.EOF) Then
oRS.AddNew
oRS.Fields("Item").Value = item
oRS.Fields("Occurrences").Value = 1
Else
oRS.Fields("Occurrences").Value = oRS.Fields("Occurrences").Value + 1
End If
oRS.Update
oRS.Filter = ""
Next
oRS.Sort = "Occurrences DESC"
oRS.MoveFirst
Set CountValues_Recordset = oRS
End Function
And using it to achieve the output you want:
Dim myArray, oRS
myArray = Array("happy", "hello", "hello", "testing", "hello", "test", "hello", "happy")
Set oRS = CountValues_Recordset(myArray)
Do Until oRS.EOF
Response.Write(oRS("item") & " " & oRS("Occurrences") & "<br />")
oRS.MoveNext
Loop
oRS.Close
Set oRS = Nothing
Don't forget to close and dispose the recordset after using it.
