View 11 RepliesWay To Concatenate List Of Strings Into A Comma-separated Strings, Where Strings Are Members Of An Object?
Oct 16, 2009Say I have a List(Of Tag) with Tag being an object.

View 39 RepliesPrepend A String To All Strings In A List Of Strings?
Aug 5, 2010I have a list of strings. For each string in that list, I want to prepend another string. I wrote a method to do it, but I was wondering if there was something already in .NET I could use to do this. It seems like something that could be built in, but I was not able to find anything.
Here is the method I wrote:
Private Function PrependToAllInList(ByRef inputList As List(Of String), ByRef prependString As String) As List(Of String)
Dim returnList As List(Of String) = New List(Of String)
For Each inputString As String In inputList
returnList.Add(String.Format("{0}{1}", prependString, inputString))
[code].....
It works, but I would rather use built in functions whenever possible.
VS 2008 Using List Of Strings Or Array Of Strings?
Oct 16, 2009I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?
Find Strings Inside Strings?
Aug 15, 2011I have been looking for examples to find the string between two strings. This top one works fine;
Public Sub ReadData(ByRef keywordStart As String, ByRef keywordEnd As String, ByVal filename As String)
Using reader = New StreamReader(filename)
[Code].....
Now the first one is fine - Ext_Volume is result of the string between the strings <Volume> and </Volume>. <Volume> and </Volume> are unique so this is straight forward.
However the second one - "^FDExp:" is unique, but "^FS" is not unique. There are occurances of "^FS" before and after "^FDExp:".
How do I get the string to search AFTER the occurrence, not before etc?

View 2 RepliesDataGridView - Convert Nulls To Empty Strings And Display It In The Grid As Empty Strings
May 14, 2009I have a DataGridView that has some columns with dates. It binds to an in-memory Datatable which gets loaded from an string array of data passed back from the backend Some of the rows returned have nulls for the date columns. Solution 1: If I define the Date column in the DataTable as "string" I can easily convert those nulls to empty strings and display it in the grid as empty strings (desired results). However, if the user clicks on the date column header to sort by date, it doesn't order the rows as you want. You get a purely string sort order. Not acceptable

Insert To Sql Via OLEDB Connection - Including (already Accomplished Image Insert Directly Into The DB)?
Aug 20, 2009im trying to write to an sql database. im inserting an image, as well as some other information. I am using the following code which works fine, as long as i do not add an extra column/variable "LOCATION" in to the mix and leave "
'Cmd.Parameters.Add("@LOCATION", OleDb.OleDbType., 3).Value = "testing"
commented out. *this is undesireable as im trying to add extra criteria to be saved like LOCATION.
Try
Dim st As New FileStream("\serverfolder1storage" & "pdftemplate.jpg", FileMode.Open, FileAccess.Read)
Dim mbr As BinaryReader = New BinaryReader(st)
Dim buffer(st.Length) As Byte
[code]....
i am trying to store the location e.g "c:file1.jpg" in the sql db. Can anyone reccomend a solution to this using OLEDB? ideally i need to add approx 4 more variables. e,g
firstname
surname
dob
location

Insert An Additional Row On Insert Into SQL Table?
Jun 28, 2010I have a csv file that I need to import into a sql table, this portion is working correctly. The code grabs the data, displays it in a datagridview and then imports it into the sql table. What I need to do is add an additional field that will automatically number itself by the amount of rows inserted at that perticaular moment. Let me explain a little clearer. The data I grab from the csv file is a day snapshot broken down to the hour. So lets use todays date 6/28/2010 will be broken down in the csv file like this:
Date
Time
Num#1
Num#2

Best Way To Manage Strings?
Aug 21, 2010I am writing a program that uses an array with three columns and a varying amount of rows. I need to load info on a list of files in an archive(specifically: file name, size, path), and I am wondering what the most convenient way to store strings(to be loaded into the array) is.
For example: I tried creating a new .resx file in my project, and writing a function to be executed on form1_load that reads the strings from the .resx file and places them in the array in their correct column, but unfortunately had no success.
I really have no idea how resx files work, I can put strings in them using the resource editor, but I don't know how to retrieve them using resourcemanager.
I would just put the info straight into an array, but it's much easier to update a .resx file when the archive changes than it is to update the code.
Could someone please tell me how to use .resx files in vb.net? Or an easier way of accomplishing my goal?
