I need to build a comma-delimited string from an array.
For i=0 to ubound(arr)
str+= arr(i) & ","
Next i
The trouble is that I end up with an extra comma at the end.
My current method for removing the comma is:
If str<>"" then
Left(str, Len(str) - 1)
End if
But it seems pretty untidy, and non-generic. I have to do this so often, it's become a pain.
I'm having a little trouble with this... I have a Session variable which contains a string of comma separated ID's which needs to be passed to a stored procedure but if it is more than 8000 characters, it needs to be split into more comma separated strings. For example;

I have a simple question about string concatenation. Following is the code. I want to ask why s6 = "abcde" and not "akcde"? I have change the s2 value to "k".

I am manually building up a SQL UPDATE statement out of "SET Column = @param," strings. The problem I have is that the last one of these SET statements before the WHERE, should not contain a comma, as that is as syntax error.
So my code looks like this:
Public Sub Update(byval id as Integer, Optional byval col1 as String = Nothing, Optional byval col2 as Integer = -1)
Dim sqlupdateid As SqlParameter
Dim sqlupdatecol1 As SqlParameter
Dim sqlupdatecol2 As SqlParameter
[Code]....
Can anybody suggest a better algorithm to remove the last comma before the WHERE in the SQL statement, keeping in mind that the number of SET statements before it will vary?
As I'm adding a comma after each set, since another one can follow or not follow, so I have to after building up the UPDATE, go find that last comma and remove it.
So it should look like this:
UPDATE dbo.MyTable SET Col1 = @col1, SET Col2 = @col2 WHERE id = @id
I have the following code:
FormatNumber(.Item("Class_RAmt").ToString(), 2)
It able to convert the string to number, but the result is 1,200.00. How can I remove the comma within the number for example, 1200.00 instead of 1,200.00.

View 1 RepliesI need a regular expression that can validate that a string is an alphanumeric comma delimited string.
Examples:
123, 4A67, GGG, 767 would be valid.
12333, 78787&*, GH778 would be invalid
fghkjhfdg8797< would be invalid
This is what I have so far, but isn't quite right: ^(?=.*[a-zA-Z0-9][,]).*$
when i clicked the final button to display my results "as string" it still showeed the number?? here is the code i wrote, is relativley simple, but the theory doesnt make scence to me Basicly its a box with 3 lables, (first name, surname and age), 3 text boxes (for the user to input this info) and a button at the bottom called "display in message box" so when i click the button, it displays the users input in the form as a message box. [code] what i dont get is if i said to VB that vaiable "Complete" was STRING then howcome it still displays the AGE which is an Integer (a number) not a string??
View 3 Repliesi would like to split my data from string and put it into integer and invidual string as sample below:
this is the data i want:
Private total() As Integer = {10, 6, 2, 1} 'here consider length = 4
Private towns() As String = {"A", "B", "C", "D"} 'here consider length = 4
below is the data i get it now:
Dim total2 as string = "10,6,1" 'here consider length = 1
Dim towns2 as string = ""A,"B","C","D"" 'here consider length = 1
how to split the total2 and towns2 i get and split into total() and towns() i want.
it is i need to write a for loop to split the string by comma?
I used a built in function to create comma separated string using List easily.(It is not split and join but new function) I'm not able to recollect or find it. If some one knows about it and uses it please post a link to that. Framework - .net 2.0
(It is not Join or split - I know about this, .net has new built in function to create CSV format)
Check Jacob G Answer below for what i was looking for let me know your thoughts on it compared to join ;)
And whoever gave me -ve rep need to keep some patience and not hurry

View 1 RepliesI've got this string which looks like this:
Gabriel, Peter
And I want this string to look like this:
Peter Gabriel
I know about the replace and split functions, but I'm not sure how I can make this as simple as possible without messing around too much?
Here's the code
Dim strDisplayName as string
strDisplayName = "Gabriel, Peter"
Dim strTemp() As String
strTemp = Split(strDisplayName, ",")
strTemp(1) = Replace(strTemp(1), " ", "")
strDisplayName = strTemp(1) & " " & strTemp(0)
I'm trying to parse csv file with VB.NET.csv files contains value like 0,"1,2,3",4 which splits in 5 instead of 3. There are many examples with other languages in Stockoverflow but I can't implement it in VB.NET.Here is my code so far but it doesn't work...
Dim t As String() = Regex.Split(str(i), ",(?=([^""]*""[^""]*"")*[^""]*$)")
I'm trying to write two regex's - you'll need to tell me if they're even possible. Both are based on VB.net syntax.
Regex 1:
The string I'm testing against -
Size on disk: 25,754,900,936 bytes
It has a handful of leading spaces, but the text is ALWAYS the same. I'm trying to extract out just the number (25,754,900,936).
I've tried a handful of regex's, but I can't get everything on one line. The commas are messing me up and returning multiple matches (For example, d+W+ gives me four matches, one for each set of numbers separated by commas.)
The best I've done is [0-9/,]* but that gives me 25 empty matches and one match (On match 19) of the number. I need this to match on match 1.

I am reading a csv file in VB.net and saving the line to a SQL database. At a later point in my code, the SQL line is retrieved in the application, and the Split function is used to get 'field' values. The Split is done taking comma as the separator. The application processes many other files (including excel), and the split function is used for all of them. The problem I am now facing is that one of the csv files I read, has a field value that starts with " followed by multiple values separated by a comma and ends with another ". The normal reading of the csv file results in each of those single field values is taken to be a separate value.
An example line is:
Elker,MissB,"Bus, Taxi, Train, Ferry, Parking, Toll",800253
Where there should only be separated to 4 columns, they get separated to 9 columns instead. What I want to do is replaced the commas after 'Bus' and until 'Toll' with a '?' instead. I have tried using Replace, including the overloaded one with starting position, but it ends up replacing ALL the commas in the line with '?'
Attempt 1:
If vstrLine(intStartPos) = "," Then
strRetVal = Replace(vstrLine(intStartPos), ",", "?")
end if
Where vstrLine is Elker,MissB,"Bus, Taxi, Train, Ferry, Parking, Toll",800253
and intStartPos is the first instance of a comma after the "
It returns only the '?' and not the string with 1 comma replaced by '?'
Attempt 2:
If vstrLine(intStartPos) = "," Then
strRetVal = Replace(vstrLine, ",", "?", intStartPos)
end if
It returns a string with all commas replaced with '?'
What i want to do is take particular values from a list of strings and store them into variables for that particular index.

VB.NET 2010/ASP.NET 4. I am using a web service which returns a string like this:
US,"UNITED STATES",MN,MINNESOTA,"MAPLE GROVE",45.1234,-93.4947,613,763,AMERICA/CHICAGO,NA,55311,"COMCAST CABLE","COMCAST CABLE",COMCAST.NET,"AS13367 COMCAST CABLE COMMUNICATIONS HOLDINGS, INC",CABLE/DSL,RESIDENTIAL,3,99,35,96,,
If I split by comma it's usually fine except in the above string I have the following:
"AS13367 COMCAST CABLE COMMUNICATIONS HOLDINGS, INC"
Which contains a comma and splits into two. This I don't want.
How to see if this field (array(15)) contains a comma & if it does to leave it intact into one array field? It's always constant in the same place in the array
Example:
(14) = COMCAST.NET
(15) = "AS13367 COMCAST CABLE COMMUNICATIONS HOLDINGS"
(16) = "INC"
(17) = CABLE/DSL
But I wish to keep it so it's:
(14) = COMCAST.NET
(15) = "AS13367 COMCAST CABLE COMMUNICATIONS HOLDINGS, INC"
(16) = CABLE/DSL
I have string 12.3.2010,13.3.2010,14.3.2010,15.3.2010
And how to check for example: is 12.3.2010 member of this string up.
If it is, messagebox ("true")
If it isn't, messagebox ("false")
It's important to say that size of the string is not specified, so it can have more dates.
