First of all - It`s my first post here so welcome I have a short question.I have an array with strings values, and a datacolumn with values of the same data type. The question is - what is the most efficient method to find values which are in the array, but aren`t in the datacolumn?
View 18 RepliesI got a value which is store in the array and i need to compare it. Which
if my user = 1,2,3,4,5,6 then ignore
if my user = 2,3,4,5,6 then i need to add in a ,1 which become 2,3,4,5,6,1
Here is my coding
user = dr("user_access")
dr.Close()
Dim splitX As String() = user.Split(","c)
For Each item As String In splitX
[Code] .....
Is there other way to compare the array or there is another better way to check?
I'm trying to compare images for a slot game, and I'm pulling images from an array for this, but I get the error message:
"Operater '=' is not defined for 'System.Drawing.Image' and 'System.Drawing.Image'"
If imgSlot1.Image imgSlot2 Or imgSlot1 = imgSlot3 Then
Points = Points + 10

I have a whole bunch of information that has been parsed from a web page and i want to insert the data into a multi-demensional array and the compare the data of a certain array element to another array in the same format to determine which is missing/added.So if i have this:
Type of animal | Color | Age
Cat, Brown, 15
Dog, Pink, 6
Fish, Orange, 4
[code].....
I only want to compare the type of the animal and the color and age is irrelevant.I want it to let me know whats missing and what's been added.Sounds bizarre but yeah. It doesn't need to be arrays, it's the only thing i know of though.
I have a DataColumn and call the MaxLength Property on it to get the length of data that can go into a field ... but it always returns -1 (yes even on a string field).
View 8 RepliesBasically what I'm trying to do is this, I have 20 statements in a Select Case (right now they're just labels for my own testing), I have a random number generator that will generate a number between 1 and 20. Since I don't want the same statement to repeat during the individual run of the program I'm trying to generate a random number, then check it in a dupeCheck method, then if it isn't a dupe I'm trying to return it to the select case and put it in the array so that when I choose the next random number if it's the same the dupe check method will catch it and return a False boolean and then the random method will do a recursive call to itself to generate a new random number and the whole thing starts again. I'm populating the numbers into the select case just fine, but VB keeps telling me that my functions aren't returning values on all paths, and stepping through I can see that the recursion isn't happening and that it's just sending the repeat number back, but I can't figure out where my major issue is. I'll show you my current skeleton code for the "GuessOrDie" as well as the first manifestation of the code I wrote for it a couple of days ago (the old code had infinite recursive calls and array out of bound exceptions)
I would really love it if you guys could take a look and let me know what mistakes I'm making, I'm having big problems moving from FOR loops in java to For/Each loops in VB and I suspect that is a big part of my problem.
Current Code:
Public Class GuessOrDie
Dim questHistoryArray(19) As Integer
Dim indexCount As Integer

I have two array list same size, depending on the information gathered by previous functions. The size of the arrays range from 2 - 45 in length, both arrays always have the same length. I am trying to match one string in one array to another string in the second array. When they match then add Item to List.
Here is my
Do Until i = Arraylenght
info = Replace(myAL(s), " ", "")
SortedArrayList(m) = Replace(SortedArrayList(m), " ", "")
SortedLine = Split(SortedArrayList(m), "Price=")
If myAL(s).Contains(SortedLine(1)) Then
[Code] .....
This code works up to an array of not more then 4 in lenght, when working larger size array then 4, the minute it get to 5 I get this Error:
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
I have a query in Access 07 that identifies the following fields: ContractID, status, start date and end date. For each contract, I've been able to search a network share and upload its corresponding file; however I need to skip the import and write a record to a table for contracts with the same start and end date. I've included a placeholder (in bold below), but how do I make the date comparison work? Do I need to create a multi-dimensional array for that or can it be done with the code I have?

I have a program that reads in lottery results from the past 6 months (from the national lottery site) from a text file
31-Mar-2010,29,18,38,44,14,43,13,3,GUINEVERE
27-Mar-2010,32,38,11,15,42,6,24,2,GUINEVERE
24-Mar-2010,3,49,28,5,23,42,41,4,GUINEVERE
and stores it in an array (n-1,6) where n is the number of lottery lines, so the array looks like
0 1 2 3 4 5 6
0 29 18 38 44 14 43 13
1 32 38 11 15 42 6 24
then, in a 1D array I store the player's numbers, simply as
0 23
1 16
2 19
[code]....
I want it to take each number from the player's number array individually and compare them to each row individually in the lotto results array i.e. the first six cells in each row in the results array will be compared with each user number to find any matches, if a value matches then a count is incremented. if the count is greater than 2 but i'm getting no where with it :( i've been trying to use the For To loops but keep getting index out of range, or else nothing is happening at all!
I've had no issues with this in C++, however, in Visual Basic 2008 (not sure about 2010), when I run a Do loop of any type, and run a comparison to 0, or even 0.0, the code loops a second time.
[Code]...
To my knowledge it should cancel after the 5th line, since the condition is satisfied. However it does not. Instead it runs the loop one last time.If I put in a comparison of any number higher or lower than 0, it works as it should, and cancels properly when the 5th line is written. So 1, -3, 0.0001, etc. works, so the problem lies with 0.
Now I do not know that much about the debugger, but it should be mentioned I'm running express edition, and I could not find anything that lets me see how each line compares. Nor, after an hour of searching online, could I find a single forum where this is answered (though perhaps that is due to how I worded my search).
If someone could explain to me why the comparison does not work as it should and loops a second time when comparing to 0, or even 0.0 (one person thought it was a difference in balance being double and 0 being an integer),
How do I check if 1 file is the same as another file? For example, lets say I have to files. Both have the same name, but different contents. How would I "compare" the files and tell if they are the same or different?

View 9 RepliesI'm wondering if there is another way of comparing two byte arrays, that isn't going through each index of the array.[code]But that would give me false negatives. If I wanted the real results then I would have to add a Not.
View 4 RepliesI try to read the ID3 Info from a .mp3 file by reading bytes, and then i convert it to a string, and try to compare it to a string (that contains the same word(s)) but wasnt a byte stream beforehand anyhow ALL of my converted strings have a length of 31, regardless of if its a string that says "John" or a string that says "Teenage Mutant Ninja Turtles" how can i make my converted string have the correct length? John = 4 NOT 31!!??

I am coding a program for a movie trivia game that randomly shows a movie quote and the the user selects a movie name from a combo box that matches. I used a array for the movie quotes and a comboBox for the movie names. I have coded a portion of the program but I am stuck on how to compare the array quote being shown to what movie the user selects from the comboBox. I have tried numerous different things but none seem to work right. The way I have it coded now it shows that every movie I pick that it is right even if it is wrong. I am going to show part of the code here and also attach the entire solution for anyone that needs it .

This is the code I have in one button and I have 2 listboxes that will be filled with the info it gets.This code should compare 1 avi file to one jpg file and see if they have the same name. If YES then it will add the avi path to one listbox. If they don't have the same name OR the .jpg doesn't exists it will add avi path to another listbox.. But currently it is adding the avi name to both listboxes.

I am making a app that reads options of a ini
dim config as new iniconfigsource("patch.ini")
dim test as string = config.configs("news").getstring("test")
Then I made a dropdown with options
I want my script to compare the values of the dropdown with the string readed from the ini
then uses it as selected value (the so called standard value) the one uc without clicking on the arrow if the none of the values match with the string value of the ini then it executes

I have a combobox that displays saved names from the fullname column of my database. This works fine, all the items under the fullname column are added to the combobox.

I have these list of RS-232 strings declared in my public class
Public Class TouchInterface
Dim WatchTVbtnCmd As String = "rs232command1"
Dim VolUpbtnCmd As String = "rs232command2"

Dim RadiobtnCmd As String = "rs232command5"
Dim MusicbtnCmd As String = "rs232command6"
I then have this private sub. For the sake of this thread, what I would like to do is get the name of the label that was clicked which in the code below is already done, convert it to string (not sure if this needs to be done), this is also done in the code below. Next I want to compare the labelnamestring to all the variables in the public class to find out which one it is equal to and then disply that variable which should be my rs232 string in the message box. I have also added "Cmd" to the variable names above so I also need to work out how to add the text "Cmd" to the string to properly compare.

I was just wondering if a computer would add two numbers together (positive) faster that comparing two numbers.
I was thinking that it would be comparison (best case) due to the fact that the 0th bits could be different right off the bat. Where as when adding, moving from bit 0 to N is mandatory for addition.
But then again a computer may add/compare differently than I am imagining.

I'm trying to make a Lottery program on visual basic 2008, but there's one thing that I am stuck with.Note: My explanation may be hard to understand, so if you would rather have me send you my code and see how it works, I'm fine with that. My code is pretty long so far, so I didn't know if i should post it on here.
My program has 6 picture boxes lined up horizontally, and has one text box underneath each one. There is a play and stop button on the bottom left corner.I've altered my program to have animations for the picture boxes. Instead of having a random picture picked, I have it so that each picture box scrolls through a series of 10 numbers when the user presses play.
When the player presses stop, the picture boxes stops scrolling, and random pictures are displayed in each box. (The picture is really just a black circle with a number in it).The text boxes below the picture boxes are for the user to put numbers in. These are the numbers they select for the lottery. Now this is my predicament. Since the picture boxes decides what the winning lotto numbers are, how can I compare the numbers in the text box to the pictures?

View 2 RepliesBasically I have and array of integers that vary in size. I need to compare each number to each other number and display which number is repeated. For example:
Dim ints() As Integer = {1,2,2,5,4,6}
The number that shows up more than once is 2.
How can I run through the array and compare each integer with the numbers in the array. I tried a for loop but it didn't return the value I was looking for.
How do I go about adding a ButtonColumn to a DataTable.
I am basically using a DataTable as the DataSource of a DataGrid and need to add a ButtonColumn to the DataTable so that when I DataBind it to the DataGrid it all works.
Although when I try
dt.Columns.Add(buttonColumn)
This is not allowed. It has to be a basic DataColumn.
Anyone have any ideas what would prevent my data from not be ing able to be bound to my data column? [code]My error says cant bind to column named SellingPrice? I have many other columns ALL binding the same way and other parts of my program recognize SellingPrice ?
