Program That Will Compare Array Of Grocery List Items Glist And Array Of Coupon Item List

May 27, 2012

I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?

VS 2010 Compare Image Byte Array?

Dec 25, 2011

and i need to convert the image into a text.now anyone thinking that i can just use ocr is unfortunatly wrong i have tried about 5 of them and they dont work because the text in the image is to small for it to recognise it.so i need to search the above image for a smaller image such as this.so by doing this if i get a result saying true then i will be able to go from be there and convert to text.now i know of two way to search an image for a smaller image. first is by going by pixel search and well i can get that to work but it is to slow.the second method is to convert the image to a byte array(beig an image it will be a 2d byte array) and convert the other image to a byte array and then compare.

Compare Field Values Based On The Value In An Array Using Access07?

Aug 11, 2009

I have a query I'm using to identify a group of contracts that have expired. The query has a ContractID, Status, Start Date and End Date. For each contract, I need to go to a directory and search for a file to import. That part works just fine, but how can I put a qualifier in to check for contracts that have the same start and end date? Do I need to create a multi-dimensional array for this or can I use the query I have? The part in bold text is where I need to identify identical start/end dates. Comments identify pieces to be developed and message boxes to help me confirm what's happening as I run the code:

Private Sub cmdRefreshList_Click()
DoCmd.SetWarnings False

'Create an array based on the true-up contract IDs.

Dim db As Database, TUrst, PYMTrst As Recordset

Compare The Value Of Two/multi Column Array And Add Into Listbox Without Duplication In Visual Basic?

May 2, 2012

I've small project to do and now I'm stuck in middle. The program is to read the sequential text file and load it into a array/array of structure.The data information is like this (sample):

ID | Name | Type
1 | Cat | Animal
2 | Dog | Animal

[code]....

This is Just as sample data, my original data is more than this.I've open the DATA.txt file using FileStreamReader:

Dim FileStreamReader As StreamReader = New StreamREader(DATA.txt)

Read all the elements in the list and pass through ReadArrayString.Split the string using:

DataString.Split(New Char() {";"c})

Pass through

ReadArrayString(0)
ReadArrayString(1)
ReadArrayString(2)

Where index 0 is the ID, index 1 is the name, and index 2 is the Type Then I load the types in the dropdown combobox menu from the array with out duplication. Like this:

If TypeComboBox.FindString(ReadArrayString(2)) < 0 Then
TypeComboBox.Items.Add(ReadArrayString(2))
End If

Now When you click TypeComboBox it will show drop down menu with following list only.

Animal
Bird
Fish

After this, when Animal type is selected/clicked from combobox dropdown menu then it should only add the Id and Name of Animal type in the ListBox.Pseudocode may looks like this:

If Animal is selected/clicked from TypeComboBox then
Add Cat into listbox
Add Dog into listbox

[code]....

I've only figure out load items from only one column/array into combobox with out duplication.But can't figure out to compare the value of one column/array with another column/array and load it into listbox. I don't want to hardcode or write matching value inside the code. What I want is use the Array.

Parsing Through List, Compare 2 Dimensional Array Element And Replace With Higher Value?

Mar 23, 2008

unordered text file of 3 columns to assign into 2 arrays. I've been given a graphing component which expects a two dimensional array for a scatter graph for the set of values in the last column.

How would I parse through the list given an indexed array of 215 possible 'zone alarm locations' and if an alarm log list item, of which there can more than one for any given zone location, compare in the two dimensional array any previous value and replace it with the higher valued one? The following are my declarations for the 2 arrays. It isn't clear to me why the array for the scatter data was defined as (999,1) knowing there are only 215 possible x values (alarm zone locations)

Changing The Value Of An Array Through A Foreach Statement?

Jun 13, 2012

I am making a program that automates the seperation of a csv file. We read the csv in through and then assign the "line" using a split command to an array. After that we go through each "cell" in the array and put an = in front because this causes leading zeros not to be lost. Here's the code.

arLine = line.Split(replace)
For Each cell As String In arLine
cell = cell.Replace(",", "")
cell = String.Format(cellFormat, cell)
Next

arLine is the array and replace is the delimiter, in this case a pipe not that it matters.'

When it goes through, the arLine is correct but the values in each cell are not changing, any thoughts? newer to VB.net and need direction

VS 2008 Coding An If Statement From An Array To An Event?

May 1, 2010

I'm trying to make a show/hide button. I want the show hide button to be attached to an object on a form. Right now I just have separate show/hide buttons set the 'visible' property to true/false respectively. I want to code something that will consolidate the two properties. But I don't know how to code an if statement into an event, in this case the click event.

I'm thinking I'd have to do something like create an array (which I'd have to read a tutorial on first) that would hold two numbers. So, if the object on my forum's default visible property is true then if the button was clicked once it would be set to false (1) and clicked again it would be true (2). So, the array would only remember two values (1 and 2) and I'd have to create something else that would remember the previous value (say, 2) and than get the array to spit out the only other value (say, 1) it holds. Then finally strip the value the array spit out and have it go through some kind of if statement that would set the true/false value.

Without posting the exact code I'd need to pull it off, how would I go about doing this? Am I on the right track, or is there a simpler way? I'm new to programming.

I'm in the middle of making a battleship game, and I'm trying to get picture boxes .visible=True based on the coordinates (that have already been given a nice Try/Catch/Finally error handeling block) of the ships. Example: I have picture boxes in a grid formation that are all red, and my naming convention for them is picR00 for the coordinates (0,0), picR01 for the coordinates (0,1)... et al. Because I'm using a(10,10) for my boolean array, I want the stuff thats false (not marked), those coordinates' red picture box to become visible, and the true have the green ones become visible. Here is what i have so far:

Dim a(10, 10) As Boolean, b(10, 10) As Boolean, c As Integer, x As Integer, y As Integer, ox As Integer, oy As Integer
For c = 1 To 3

Structure Statement Using Module Level Array To Read File

Nov 27, 2008

Define a structure named product, The structure should contain 2 variables one as a string and the other as a decimal. The decimal is used to store the price and the string is used to store the item number.

Declare a module level array that contains 5 product structure variables

Code the main forms load event procedure so that it reads the item number and prices from the itemInfo.txt file The procedure should store the item numbers and prices in the module level array. It also should add the item numbers to the list box.

When the user selects an item in the list box the items price should appear in the xPriceLabel. code the appropriate procedure.

The code I have is as follows

' Project name: Glovers Project
' Project purpose: The project displays the price of an item.
' Created/revised: <your name> on <current date>

[Code].....

Seems the problem I am having is this line is returning a value less than 0.

If <expression> Then <statement [:statement]> Else [statements] In Concrete Form?

I was convinced that If <expression> Then <statement [:statement]> Else [statements] in concrete form of If a = b Then SayHello() Else SayBye() End has sense. I read article on msdn on If-then-else, but I forgot why I was reading, so I concluded, that snippet above means this

If a = b Then HelloIsSaid : IsNotEnded Else ByeIsSaid : IsEnded But I have tested it now, and I see, that Else without statement is nothing more than decoration. It would be pretty good if it had function I described. Do you think its good request? Or do you know any circumstance where this Else has some function?
