Split Previously Joined Numbers To Original Combination?
May 17, 2010
Number1 = String.Concat(2, 106, 15, 233) Which will be 210615233.I am dealing with a problem in which I want to join some numbers then I come back again and split them up. The problem here I cannot save the original combination. Is there an Anti-concat method with saving the original combinations?For example, if I joined 3, 10, 4, 0 and 323 = 31040323. After some operations in my code I want to come back and split them up to the original combination of (3,10,4....etc). Please note that I am doing this not for one number, it is for many numbers.

I would like to be able to add every combination of a list of numbers to determine which combinations equal a specific result.
Simple Example:
List: 2, 4, 6
Result: 10
How many and which combinations of numbers result in the number 10? The correct anwser is only one which is 4 + 6 = 10. The example is simple but the actual list may contain as many as 10 - 15 decimal numbers.
I have thought of the following as a possible way of checking each combination by using binary:
- There are 3 total number so the possible combinations would be:
123 - Three numbers
000 - Add no numbers
001 - Add the last number
[Code].....
However, I don't know how to actually match up the bitwise bits to the numbers in the array to actually add. Example:
101 - I should check if 2 + 6 != 10 per the example above so this wouldn't satisfy the result... does this make sense? The answer would be 4 + 6 = 10.
how to check and add all combinations from a list of numbers to determine if the result is a specific number?

I'm looking for some function to put together every possible combination of letters and number to create a string that is 14 characters long. I have found ways to make every possible combination of letters and numbers seperately. However, I've never run across anything to come up with them together. Every string created must contain letters and numbers.I just have no idea where to start on this one.

I'm working on a program and in it I need to store all combination's of the numbers 1,2,3,4. I would like each combination to be it's own array, and instead of creating 24 different arrays (there are 24 different combinations 1,2,3 and 4 can be arranged) I was wondering if it's possible to create a nested array like so:
[ [1,2,3,4], [1,2,4,3], [1,3,4,2], [1,3,2,4] .......]
That way, I'd be able to reference index 2 of the above array and have the array [1,3,4,2] returned.I looked into multidimensional arrays, but this would require me calling each index of the row and column.I also looked into making a Structure in which there was an array that could hold 4 numbers, but wasn't sure if going that method would be practical or not.

I need to get information from two tables onto my form. I'm using a DataGrid called SQLGrid which I'm populating in code with the information I need to get out of both tables.
Private connstr As String = "Data Source=MAUDOT3;" & _
"Initial Catalog=ExxColl;" & _
"Integrated Security=True;"
[code].....
I need my application to be able to update the DataGrid, and commit those updates to the database. My problem is that all the research I've done so far has led me to believe that there's no way I can do this because the SqlDataAdapter.Update() method only updates 1 single table.I just had an idea to make my event handler execute a stored procedure that creates a view on the database, populates it with data from my dataset, and then distributes the information between the two tables where needed.I guess another solution would be to use 2 DataGrids and then tie each of them into a seperate DataAdapter/DataSet, and then update each when the Event is called. The problem here would be that it's more work for the end user to make changes, so I'd really prefer to do it another way.

When I update a record at table [Product] with the integer that stands for [Supplier Name] from joined table [Suppliers], this does not appear in my datagridview. Instead, I have to reload the table to dataset to make it visible. What about datarelation? Is it better that loading a joined table over the dataset? Note that I have never dealed with datarelations before.. How can I make a datagrid column to show "Supplier Name" instead of recordID that represents this supplier?

I am using VB 2005 professional and SQL Server 2005 express edition.
For the last two weeks I have been trying to have a datagridview control on a form that will have datasource from a dataset with two tables that are related. I want child the column to be a ComboBoxColumn where userts can select options and update the other data(from the other table).
I have two tables in an sql server 2005 database named computers:-
computers
locations
Table computers looks like thisID is the primary key column)
ID Location
Computer139
Computer240
[Code].....
With the location column being a ComboBoxColumn so that when a user enters a new ID say Computer5,they have a choice of a dropdownmenu for the Location column. In the database table computers the item should be saved as well as the index value(to correspond to the LocationID).

I am trying to split a long string based on an array of words. For Example:Words: trying, long, array Sentence: "I am trying to split a long string based on an array of words."Resulting string array:Multiple instances of the same word is likely, so having two instances of trying cause a split, or of array, will probably happen.

I have multiple tables that I need to pull and display data from. I have created a new query in the TableAdapter of one table to pull data from related tables based on a parameter. In the Query Designer I can run my query and see all of the columns requested in my SELECT statement, however when I bind this table to a DataGridView and call the new query, it only returns the original columns from Table1.How do I see all of the columns I selected in my query?

I'm working on a very basic VB.net frontend for an Access database and have stumbled upon a problem.
Dim ds As DataSet
MaxRows = ds.Tables("Course_assignmentsDataSet.tblCourse").Rows.Count
i = 0
Private Sub Navigate()
txtCourseReference.Text = ds.Tables("Course_assignmentsDataSet.tblCourse").Rows(i).Item(1)
txtCourseName.Text = ds.Tables("Course_assignmentsDataSet.tblCourse").Rows(i).Item(2)
End Sub
I get the error that Object Reference is not set to an instance of an Object. I think this is because I haven't defined the DataSet as "Course_assignmentsDataSet"- the one I want to use- but I'm not sure how to do this.

I need to work with a previously stored listbox. Example: You save a file and it comes in the listbox, I can click it and I see it in all my textboxes. And if I restart the program it's still in the list. The files can be anywhere on the computer, that's why I need this method. The name that need to be in the listbox is the name of the save file.

Not sure exactly what I need to do to make this work, so my description may be lacking at first.Essentially I am writing a program launcher that recreates itself each time on load. It pulls the data regarding the tabs and buttons from an SQLite database and builds itself dynamically at run time. I get my problem when I pass the tab name through to the function that creates the buttons. I need the name to pull the right set of buttons from the database and I then tried to use the name to place the buttons on the right tab when I create them, but the debugger calls it a null reference because it doesn't point correctly to the tabpage that I'm trying to make it point to (at least that is what I'm guessing). Any ideas on how to make this work right?
