I have to order a table following a logical order but I cannot find the appropriate ORDER BY clause.To simplify I have 2 fields field1 and field2
1 record : field1 contains �2� and field2 contains �1�
2 record : field1 contains �1� and field2 contains �2�
3 record : field1 contains �2� and field2 contains �2�

I have a combo box bound to a datasource. I need to change one combo box (of many) to order the items in descending order.I'm guessing I could order the collection in the dataset, but that will mean all my combo boxes will be reordered?
View 2 RepliesI have a databound Datagridview. The DGV is bound to a datatable of a strongly typed DataSet created using the wizard. Is there any way to re order the columns before displaying them eg: the Columns are displayed in the DGV in this other Col4, Col6, Col3, Col1,Col5, Col2
But I want to it to show as Col1, Col2, col3, Col4, Col5, Col6?
I realise that the display order followed the Column order in the database table and by extension, the datatable. I have re-arranged the columns in the Database but the Datatable still retains the old order.
This might not be so 'VB' as it is 'SQL using VB' I have an application with a built in MS Access DB. I have a table that has a column full of integers, I shoot the DB a SQL "order by 'column name' " string and it returns the table ordered by my column of integers.BUT it returns them like this, and I want them like this

How do I get the OrderBY to do a descending list starting with the highest number?
I'm working on the exercise page 73 (VB 2010 in 24 hours). It's basically a form with 2 text boxes, 2 text labels and a command button. It's really simple and uses this loop to cycle through the items, and tell me the name of them in a Messagebox

I'm using the following code to read in a highscores file with the score written first and the player's name written to the next line, and then display the top 3 scores or fewer if there aren't 3 scores written to the file. A highscores display should have the scores sorted with the highest first so that's what this program tries to implement.
Array.sort() isn't doing a damn thing. In fact, the program's not even reversing the arrays like it should either. I've tested array.sort() this way with the names and scores arrays given explicitly and it works fine. I thought maybe it was still reading the data as string even though it's declared otherwise but it rounds off decimals when I change the array type to Integer so I'm pretty sure it's not that.
I have no idea why reading the data in from a file changes how it's sorted. My teacher didn't understand what was going on either. Does anyone know what's going on here?

if a byte value can go up to 255 and two bytes are used to determine the length of packet payload data, how would I convert the two bytes to create one integer value?

Dim PacketLengthHigh As Integer = state.buffer(13)

When I view the Tab Order in VB 2008, everthing has a tab order number and it is in decimal form. If I click on each item, it appears that I can set the Tab Index but it is hard to see a correlation between the Tab Index and the Tab Order on the form. Most of the items on the form are not going to be tabbed to by the user.
1. Is there a way to clear the tab order and only tab to the items that the user would use and in the order that they would do it?
2. What number should the tab order start with and do you start over with the numbering on each form?
i seem to be having issues with my simple count down project. The count down work how I want it, there is also a pic of a rocket that move up when the count down button (Button4 - the form was set up in class as a quick example, so there was no need to name the buttons) is pressed. The problem is that the count down "10....1...Blast Off" shows after the rocket has moved up, I want the countdown text to show, then the rocket to move.The countdown is outputted to a ListBox.Here is my code thus far: (I have re-worked is a bit, starting to look messy)

View 5 RepliesThe code uses dynamically backgroundworkers which all workers great, but with one problem. If you were to look at line:
For Each folderPath In File.ReadAllLines("file path here")
You would see that it loops the text file, and starts background work.
The problem is that it does not list the files in order.
For example were you see "file path here" that were you put the file path.
The text file itself would look something like this:
C: est
C:VB
The program starts listing file from the C:est then goes back to C:VB then back to C:est.
I know the reason why, but I can't stop it. I tried pausing that code inside the loop, but with no luck. How would be able to list the files in order?

My form contains a datagrid and a checked listbox. The listbox is populated on the form_load event. There's a function called when the datagrid's SelectionChanged event is triggered that modifies the checkmarks in the listbox. It all works fine when I manually click on any item in the datagrid.
However, the very first time the form runs, the checkmarks are not affected, even though the first item in the datagrid appears selected. I discovered that this is because the actual listbox is not yet populated on the form at the time the very first SelectionChanged event is triggered. So when the function tries setting the checkboxes, it doesn't get anywhere, since it doesn't see any items in the listbox.
Somehow the datagrid is getting populated, even before the form_load event is triggered. I need the listbox to be populated before the datagrid is populated, but I have no idea how to control this.
I'm using visual basic 2008 express edition and I'm not sure how to attach my query in order for it to run? I've been using trying to use visual basic to create a form which retrieves data from a Microsoft access database and filters the data to find the record starting with the letter retrieved from the user. When it is run without the query the data grid shows all the records. However when my original query is put in the application changes it and the value shown is null in all fields.
This is what i had before:
SELECT Allergies, Breakfast, Lunch, Supper, FirstName, LastName, MealDate, StudentId

WHERE (LastName LIKE @LastName + '%')
This is what was returned:

View 7 RepliesI would like to ask some questions related some functions i want to make in my program:
1. I am using this function in order to get a the item code from the database Long.Parse(myReader(0)).ToString("2200000000000") the result i get is: 2200000059091. The form that i want the resultset is
22 (fix value) + item code (6 characters right justified) + 00000 (fix value) 2205909100000 how should i change my code to obtain this result?
2. The programs every time it runs creates a text file which i also attached it plu1.txt, when i try to open it with notepad i see all the lines justified, on the other hand when i open the text file with Wordpad or ConTEXT the lines are not fixed, others are longer others are shorter? What should i change in my code in order to have every line fixed lenght... The code i am using is the following
Dim myReader As SqlDataReader = myCMD.ExecuteReader()
Dim fNextResult As Boolean = True

3. third and last question is that my program every time it ends show up a pop up menu which says "Text is created." Instead of this i would like to create a file lets say log.txt and every time the program runs, it will overwrite on the log.txt file a line like this: system date + Text is created + with X lines (where X are the lines of the text plu1.txt) ex. 26-10-2009 14:56 Text file created with 15 lines

Then have that payment psoted as processed back to the DB table. I have a binding satament, but it pulls all payments, and not just per order. How can I get this to select just by order #?
