Array Subscript Have To Be Sequential?
May 6, 2009
First... does the array subscript have to be sequential? (0,1,2,3,4) Or could I pull the system date and use that? i.e. dim Beer() could have Beer(33939) for today, and then not record anything for three weeks and the next entry would be Beer(33960), etc.Along the same lines, and pointless if the answer above is yes...I'm writing a prog to handle inventory for a bar. The bar has 230 different beers at the moment. Could I create a 2-dimensional array using a product number, date for the subscript?
i.e. - for received data... recBeer(a,b)recBeer(229,33939) = 48(Meaning 48 bottles of beer #229 arrived on date 33939)SO... a is the product, b is the date. Any searches for (229,*) would provide me with the complete history of that product being received. any searches for (*,33939) would tell me all of what was received on that date.Will that work?(And yes, I'm stuck with a flat file to make this work. Much rather have a db involved.)

I am trying to copy the values to another sheet but not in any sequence eg.A1,B2,C4,D7 ........and so on. I am trying this slick way of doing it by the code below ( found on the web) without success so far but I got a feeling I am close to the solution. I am new to any kind of Programming. This is my first attempt. (so a chuckle or two is ok after seeing my "difficult" problem)

I need to put 2 different fields on the same line/row/subscript, into a one-dimensional array or list. I've done this before with a delimiter and then parsed it out later, but I wonder if there is a nicer way to do this?
I've done it this way before:
"John,Address1" PERSON_ARRAY(0)
"Greg,Address2" PERSON_ARRAY(1)

Im a college student and this is my first programming class, i am having extremely diffcult time with arrays and sequential file processing. Im not asking for the whole program, just something to get me started and hints along as i progress with it. Please help me get started on my program, its due in 2 days.
Here are the requirements....
1. The program must input any number of individual�s last and first names using two separate textboxes.
2. The array of names must be sorted by the last name using a bubble sort. You must code the sort.
3. The program must be able to recall the names from the file and add to the existing list of names so that more names can be added to, sorted, and written back to the file in sorted order.
4. Sort in ascending order: A to Z
5. All names must be displayed in a listbox in sorted order when the user wishes to see them.
6. In the listbox the last and first names must be separated by a comma and a space. Example: Smith, Mary
7. The user must be able to search for a name in the array, using the binary search algorithm. You must code the search.
8. Do not use module-level variables. Instead you may choose to use Static.
9. The program must be designed using Visual Basic 2008

I need to add a subscript (a little number next to a character, like 2 or 3 - note: not a power of...) to a string [variable]. I don't want the code to be lengthy as I will need to process a lot of formulas, one at a time.

For the past 2-3 weeks, I've been on VB Express working on different word processors, working myself up from the level of the Windows Notepad to Wordpad, and eventually (hopefully) something as good as OpenOffice.org Writer or Microsoft Word.I'm currently stuck on something that I can't quite figure out. My question is basically this, "How do you add subscript and superscript characters (not just the few numbers in the character map) to a richtextbox control?!" I'd be very grateful to anyone who could provide me with some help in this area.

I am using decimal numbers to be able to sort correctly in Excel; however I want to have a column where they are displayed as fractions. I have made a function to convert them to fractions as text ( 1.625 converts to "1 5/8 dia."). I would like to make the 5 superscript and the 8 subscript. I can do this manually by highlighting the number and formatting, but I would like to do this in code.

My teacher as asked me to allow a user to input three pieces of information about a DVD (the ID, the title and the running time) and for the program to add that data to a sequential file. My textbook fails to explain it and I am at a loss as to where my book from last semester is located at the moment.
1. What is a sequential file?
2. How do I display information from it into a messge box?

i am coding an application where I want to populate an array with the contents of a sequential file that is already populated as salary.txt in the debug folder. Basically, I want to copy the contents of that file to an array so that I may use a code to go with the intSubscript of the array. Right now it functions as just an array for this purpose, but I want to populate the array with the sequential file first. All attempts to do this, with stream writer etc and readline, I am just getting the first item in the file. I have tried to loop it and still only the first is accessable. Driving me batty, turning to the masses for guidence.[code]

I have a working piece of code that checks that 4 out of 5 random numbers are in sequence. The numbers correspond to 5 dice rolls. I'm trying to learn VB and I think the code can be improved since it's so cumbersome. The sub checks to see if any of the numbers are duplicated and reassigns one of the duplicates to an arbitrary "11" which is outside of the 1-6 range of a single dice roll. Then the values are inserted in an array and sorted and the sequence check takes place. score of 30 is assigned if 4 of 5 of the (sorted) numbers are in order. If not in order, a score of 0 is set.
Code follows:
Private Sub OtherScores4()
'Check if any of the rolls are duplicated and reset one of the die to arbitrary "11".
If Dice1 = Dice2 Then
Dice1 = 11
End If
If Dice1 = Dice3 Then
Dice1 = 11

I am suppose to create a module level array name Product and populate a list box with the contents of a file (ItemInfo.txt) The file contains the Item ID and price of the item. (Line 1 is an item, Line 2 is a price for Line 1, Line 3 is an item, Line 4 is a price for Line 3, and so on.) The problem i'm having is when i populated the list box, I only wanted to populate the list box with the items, not everyline from the file. I guess I wanted to put elements [0], [2], [4], [6], and [8] from the Product array in the list box, but I am putting everything in there. What am I missing?here is my code so far:
' Name: Glovers Project
' Purpose: Displays the price of an item

My project uses an MS Access Database, and amongst other things records the current cost of a series of categories which are regularly updated, thereby erasing the previous entry. However, I need to retain all previous costs to produce a history graph for given periods. I have considered importing an Excel spreadsheet, but having a functioning database it seems sensible to use it.

I am working on a program in Visual Basic that incorporates using a sequential access file for a ballot type program. Each type the user clicks the save vote button, the amount of votes gets stored.
What I am trying to do is in my access file is to display the number of votes as an actual number. The way my program is written right now, the name of the candidate appears as many times as the vote was saved.
for example, if perez was voted for 4 times, in the access file perez is displayed on 4 different lines. How do I display the actual number of how many time they were voted for. I'm thinking using a counter variable, but not really sure how to really implement it in. this is what i have so far.

I am making an application that requires a sequential search to search the arrays. The search searches the user's input in the array,and if found, then it's valid, else it's invalid. I have initialized the array and done the sequential search, but apparently even the wrong input is coming out to be valid.
'initialize an array

I need to test if each key is being pressed in a specific order. At the moment, I'm just doing a test between 'Escape' and 'F12.'
All works well, until I get to F11. If I enable F11 by itself, it works fine. But if I run it in sequential order, it never fires.
Each button, with the exception of one, is disabled by default. So I have a separate method that checks, when that key is pressed, if the button is enabled and if it is, it disables it and the enables the next button.
VB.NET
Private Sub DisableEnable(ByVal btn As Button, ByVal btn1 As Button)
If btn.Enabled Then
btn.Enabled = False

This is part of the last coding that codeorder helped me with. I didn't include this in the last post because I thought this was something that I was going to be able to do. Unfortunately, it is not working properly. In addition to the controls being removed, the control rows after the removed row should be changed so it's still in sequential order. Private Sub PictureBoxRemove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Dim RowRemove As String = CType(sender, PictureBox).Name.Replace("PictureBoxRemove", "")

Working on my major project for my last year of school worth 30% and am having issues with getting screen elements (buttons, labels, picture boxes, etc.) to update before or during a sequential sub program or function.
For example, I have a series of picture boxes that require to be clicked on to activate certain commands. Here is the code for one of the picture boxes, picX3Y0, when it has been clicked on:
If picX3Y0.ImageLocation <> imageFolder + hiddenImages(3, 0) + ".png" And imagesSelected < 2 Then
If x1 = -1 Then
x1 = 3
