Mar 15, 2009i need to be able to get the difference between two strings, i found out how to get the difference with this code:

View 1 RepliesJoining Data From Two Datasets?
Nov 1, 2011All I really want to do is a join. Table 1 and Table 2 both have a number that would link the two together. I want to join two fields from Table 2 onto Table 1. I need to have two datasets because there are two different connections being made.I want to push this onto a DataGridView, which only allows a single datasource. So I'm thinking I would need to make a temp table somehow, but since I'm pulling from two different datasets I don't know if that's possible.

View 7 RepliesJoining Two SQL Server Tables Together
Jul 17, 2011I am not sure if the above title is suitable for what I mean, but basically my application has a login table with entry U_ID and I have also created another field in my other table which will store this ID from the login table.
What I want to do is, if a user with say U_ID = 1 downloads data and stores it in the
second table I would also for trackable reasons be able to store the U_ID of that user
in the second table so that I would know who downloaded the information.
How can I acheive this and if there are any example then point to them.

View 2 RepliesJoining Two Datatables Or Pivoting A Datatable?
Dec 12, 2011I have a datatable that contains 8 columns. To make this more presentable I have managed to pivot three of these columns. That will not do since I then loose 5 columns of information. To overcome this problem, I thought of just joining the two tables in vb.net.This seems more difficult than expected. LINQ are hard to learn compared to SQL. I have tried to pivot the query in SQL but am not able to.Here are the query:
"SELECT t1.Journal,t2.Kunde,t2.Kundenr,t2.Lokalitet,t2.Lokalitetnr,t2.Analyse,t2.Positive,t2.Totalt " & _

Joining LINQ Query Results For Each Item Together?
Feb 3, 2011In my application, I have a search query textbox (txtSearch) that works well with one-word queries with the following LINQ:[code]So how would I make the above query more generic (ie: able to handle any number of words in a query)?I should note that the object being queried is a List of strings pulled from an Access database. As it stands, this application only queries the database once and I'd like to keep it that way if possible.
View 3 RepliesJoining ListBoxes - Selecting Items Automatically
Sep 12, 2009I was just wondering weather it was possible to make it so that if I press the first a item on listbox1 then the first item on listbox 2 is selected aswell. For example I would like to have 2 listboxes lst1 and lst2 and I would like it so that when I select the first item on lst 1 then the first item on lst2 is automatically selected and when I select the 3rd item on lst1 then the 3rd item on lst2 is also selected.

Join Lists Or Arrays Like Outer Joining Tables In SQL?
Jun 27, 2011Basically what I'm having to do is create a program that takes a list of CaseIDs and compares them to a table on a remote SQL server. However, the table holding the CaseIDs on the remote server has nearly 120,000 records.
Currently my plan is to query all records on the remote server, save the query and the current list to tables in an Access DB file and then run an outer join to see which CaseIDs have no matching records on the remote server.
I believe this will be a much slower process than I would like. If I could load both queries into arrays or lists in VB and then compare them (therefore, not having to write 120,000 records to a DB file), it would be much faster.

View 39 RepliesHow An Application Like GameSpy Or GameRanger Launches Applications And Is Able To Sync With Other Users(all Joining Together)
Feb 14, 2010I have been trying to figure out how an application like GameSpy or GameRanger launches applications and is able to sync with other users(all joining together). I have been under the assumption that it was just simple command line switches being used. The more I look into it the more I don't think that is the case. I believe they are hooking into a game's API to do so. My question would be, using OllyDbg I was able to get the memory address of a Text display in the game(The game you are about to create's name).The default is "TEST SESH", and if you highlight the field and hit enter you can edit it. I was wondering if anyone could give me incite on how I could set this text through a DLL injection?
View 1 RepliesPass A Parameter From The Select List Into A Function For Joining A Linq Query?

Prepend 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?
