VS 2010 Two Separate Arrays And Then Compare Them?
Jul 2, 2011
I want to put the matches from a regular expression into an array or something that i can use to compare it with another array, it being the lines from a txt file names "users.txt". Code A:
[Code]...
And the second code will do the exact same thing. What i want to do is compare each line in the Txt file (Code B) to the reg expression matches (Code A) and for it to alert me if any is missing. So it needs to compare Code B to Code A. (PS. Order is irrelevant, it can be in different places as long as its there) In my other thread i got a little confused and couldn't clearly communicate what i was trying to do.

I have a program that has to store a pre-made array that contains strings (moviename, moviegenre).
I setup all the items in the array already, example:
moviearray(0,0) = "Green Lantern"
moviearray(0,1) = "Action"
For this example, if the user selected "Green Lantern" from my listbox, then the label needs to display "Action". So yeah, it's a 2-column array: first column = movie name, 2nd column = movie genre. Now, I have a listbox containing all of the movie names (not entered by the array, but entered through the Item property of the listbox). When a selection is made in the listbox and a button is clicked, I need to have the genre of the movie output to a label. That is where I am stuck, I just can't figure out to compare what's in the list box with the first column of the array to output the 2nd column to the label.

I have been trying to find out how to do this for days now, so I am finally asking how. I am newish to programming. Here is my problem.
I am trying to extract x,y,z coordinates from a text file arranged as such:
x,y,z
x,y,z
x,y,z
etc.
I need to be able to extract the x column into an array, the y into an array, and the z into an array. I learned how to pull it into a string, and how to split for every line, but i don't know how to split after each comma and separate them.

I have to write an application that has the user input data in 3 separate text-boxes and press "OK" to save it. The user can repeat this as many times as they want.I then need the application to show the information inputted in each of the 3 separate arrays. Now I was told this can either be done by using a print page or by having another form show the information. I was told having another form would work best. I guess my question(s) are: is it possible to show the information from all 3 arrays in another form? Also, is there a link to any code that can help me out in listing information from a

Is it possible to compare 2 arrays without looping? For this example, I need to compare aryFi.Count to currentarraycount. if aryFI.count>currentarraycount, then I need to add the ones in aryFi.count into a public array named pgarraylist. Since aryFi contains more items, I can't just take the .count-the difference in counts, I need a way to get the items contained in aryFi but not in currentarraycount. EDIT - currentarray is the list of currentarraycount Sounds confusing - but here's an example.
Public pgarraylist As New ArrayList
Dim aryFi As IO.FileInfo() = di.GetFiles("*.xls")
cntdif = aryFi.Count - currentarraycount 'currentarraycount is updated after changes occur and when loading program.
For y = cntdif To 1 Step -1

I am trying to make an intelligent stock pick/dispatch location system at the point of invoice from a stock database. Multiple locations are available to dispatch from, and essentially I want to make efficient dispatch, so if all items purchased can be dispatched from one location, they are grouped and dispatched as such, but if not, it groups what it can and dispatches the rest from wherever the highest stock level is available.Because the number of locations has to be variable, this system is scalable.Because the number of items is also scalable So, instead of listing suitable stock locations, I am now listing the quantity of stock available in each location for the respective items.
Items Locations
_________|__1___|___2__|__3__| - this is location IDs
Item 1 | 3 , 4 , 1 - this is the qty of stock available
[code]....
I can turn this into a string which might be used to split and create arrays
ie
stockDetails = "3,4,1|2,4,0|1,3,1|6,1,3"
Here, the comma separated values are quantity of available stock in each stock location and the pipes separate the individual items, so the table above is translated to the string above.I am not keen on multi-dimensional arrays and don't know how I'd create one without knowing how many stock locations there are.
We can safely assume That the stock quantities are in the correct order to correlate back to the stock locations IDs.
Each pipe separate series of comma separated values will have the same number of comma separated values.I just can't work out how to determine the pick locations! In the above example, all four items can actually be picked from stock location 1, providing only one of each item is purchased. Suppose though a customer bought 2 of item 3. Then the pick would have to be from location 2. All kinds of other scenarios can of course be presented depending on the number of items purchased, the quantity of items purchased and how many stock locations there are to pick from.I started off simply picking from the location with the highest available stock, but that made no sense when stock was available to pick from more than one locaton because we ended up with multiple dispatch locations which was not necessary.How can I analyse these variable length strings/arrays to determine the most intelligent way to dispatch.

I declare my 2D lists:
Dim _invoiceitems As New List(Of List(Of String))
Dim _dbitems As New List(Of List(Of String))
Each List is filled like this: Example Code To fill:
_invoiceitems.Add(New List(Of String))
_invoiceitems(0).Add("Code #")
_invoiceitems(0).Add("Quantity")
Well, now i need a third list called (_changesitems) Note that this result with the differences: be the result of subtraction of quantities if this is found (dbitems - invoiceitems).

I have a question about efficient implementation. Lets say I have two arrays:
One array is all possible items in a house: Table, Chair, TV, Fireplace, Bed
The other is an array of items in a particular house: Table, TV, Bed
I also have two list boxes:
1. listbox for items in the house - the "HAS" list box
2. listbox items not in the house - the "NEEDS" list box
I need to list the items already in the house in the "HAS" list box as well as the items that are NOT in the house in the "NEEDS" list box. It seems to me that nested "For each" loops would be a start to solving this problem but I am not exactly sure which case needs to be nested.

This new form will ask the user to enter 10 values into a textbox and click ok after each value. These values are to be stored in an array and displayed in the listbox on the previous form.I am having trouble getting the values of the user to store into my array and displaying into a list box.

I created a telephone number form where the user enters the telephone number in a text box as (nnn) nnn-nnnn. The first 3 digits in parenthesis are the ISD code, the next three are the area code and the last four are the local number. I need to separate out these three fields of the phone number and display in three separate text boxes labeled appropriately. Now, suppose the user enters the phone number in a text box as a continuous string of 10 digits, where the first three represent the ISD code, the next three represent the area code and the last four represent the local number. I'm lost as how to change this string into the form (nnn) nnn-nnnn. This is what I have

I have a TabControl object on my form with many tabs created in code (TabPages) and my problem is that the same objects that are in the initial TabPage needs to be in the other TabPages created in code, I have this done in code when the user clicks the 'New Tab' menu option, however the same code is used for any new tabs created. The problem created here is that I have an event against one of the objects that appear in the other TabPages, but because the same code is used to create any new tab pages, the event will only work on the newest tab page, if that makes sense? By the way these objects that appear on the other TabPages are properties at the top so events can be handled against them in the respective subroutine.

I'll get straight to my problem - I'm currently coding in Visual Studio.I have a table (countries) with the columns ID | Name. The table is filled with around 28 records.I also have a form with 4 combo boxes (set up as 1,2,3 & 4) that I want the user to select. These combo boxes will display the names from the table countries. I then want to use the selected names in the combo boxes to Insert into their corresponding ID into another table. For example England would have the ID 1, USA the ID 2 etc.So, is it possible to have separate combo boxes that will give separate ID values but using the same table? At the moment I can't seem to find a solution.Eventually the form will have more than 4 combo boxes so I don't want to use separate bindingsources for each combo box.

Well need to make a separate update program and I need some way of getting my main application's version. I thought about making a text file with the version but I can't write to the program files folder with permission, thats why I have a second program. I also though about making the update program's version the same as the main application, but that doesn't seem right because I have to update the update program. So is there a way I can get the main applications version inside the update program?

Basically I have a semi-solid idea of how to do this from Googling but it isn't complete as of yet since this is really advanced for my current level - but 'I' must get it done nonetheless.I am aiming to have an application which screenshots another and looks for a picture in that screenshot, compares it to one the user input and then moves the mouse to the location of that picture.
I.e. The large square represents the applications bounds, while the 4 panels are where the images could be. The images in the application will always be the same size, shape etc... and only within that area.
The user will input, into a text box say "XZ1" then the program shall take a sample picture of "X" stored locally, try and find where it is on the 4 panels and store that data. Loop till the end, then move the cursor to those three positions after all have been determined.
So far I have these sources:[URL]..But I don't know what to do for the rest in terms of writing it in code
