Now I want the user to pick first 2 alphabets manually and then on a click it will display the rest 5 randomly generated after subtracting first 2 picked ones from the whole 26 alphabets array. how this can be achieved in lists.

I was playing with ASP.NET MVC 1.0 a couple of days ago. I started out with a single table DB named 'Contacts', with very simple structure e.g. Title, FullName, SurName, Email, Phone, Address etc.I'm using LINQ as my Model.In my main view I wanted to display a list of alphabets that have matching FullNames starting with that alphabet plus the count of FullNames. Someting similar as shown below:
A - (2)
D - (4)
J - (1)
and so on.One particular thing about the display is that i don't want to display those alphabets that have no names starting with them.I tried a couple of queries but didn't succeed.
I'm creating an application that creates a list of 20 ramdomly selected numbers within an array and displaying those numbers in a listbox.

View 2 RepliesI'm trying to create a small program where someone would select one of five items from a list box (Hot, Medium, Mild, Sweet, Zesty). When they select this, they then enter in a qtyTextBox the quantity they want, ie.e, 1, 2, 3, 5,... Then they the Calculate Button, which then the total would go into the preDiscountLabel box, where it would calculate the amount they want * the sale price. Here is the Price Listing:
Hot - 3.19
Medium - 3.09
Mild - 2.98

I'm having trouble creating a global array that i can use in other functions.
I have this code right under "Public Class myClass":
Dim LoadedPlugins As Array
Then in a function I have this:
Dim PluginList As String() = Directory.GetFiles(appDir, "*.dll")
For Each Plugin As String In PluginList
Dim Asm As Assembly
[Code]....
Now obviously that doesn't work, how can I add the tmpPlugin to an array or list so I can use it in other functions?
The main thing I need to be able to do is loop through all the loaded plugins and execute the CustomFunction in a separate function than the one that loads the plugins listed above.
I've read numerous posts and threads about random number generation, but I havent' run across this.If I generate a bunch of random numbers, the results are radically different if I create a new Random generator for each number than if I use on Random generator for all the numbers. The results are much more consistent and evenly distributed if I use the same Random generator.I would have thought the opposite,because creating a new Random generator each time should reduce the number of random repetitions, if a different time slice is used to create the random number.[code]......
View 9 RepliesRecently I have learned visual basic 2008 express edition and developed programs for data crunching and analysis. The VB 2008 express edition has microsoft visual studio 2008 v. 9.0.30729.1 SP and .NET Framework version 3.5 SP1. Now I want to create x-Y (date-Y value) graphs using the crunched data stored in an array list simulating a data base access. I download and installed the "Microsoft Chart Control for .NET Framework " and try to learn to use it within the VB 2008 express edition using the tutorial. It seems that the chart control did not get installed?
1. Do I need at VB 2008 professional to allow using the chart control?
2. Why after installing chart control, there is no change on the items under the NET components within the Toolbox>ChooseItem>.
3. How do I get to use the chart control under VB 2008 express edition.
4. Any code available to generate versatile graphics without using the chart control? Because the chart control has tons of classes already it seems the best is to just use the existing and downloadable chart control?
I'm converting a user generated list box to an array and then generating a user defined number of random strings and placing it in a textbox.The code I have works fine as it will generate the number of random strings the user wants, except sometimes a line is blank at the top of the list but is counted as a string.
View 4 RepliesI 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?

View 4 RepliesI have an application with 6 cars 'racing' across the screen. Ideally I would like the random function to move only 1 of the 6 objects (cars) at one time and then loop until one car reaches a predefined finish line. However I'm not sure if this is achievable. Would I need to create a random number then create if statements?
View 8 RepliesI have a Comma Separated value file in .txt format... simply put, its a bunch of data delimited by commas and text qualifier is separated with ""For example:
"So and so","1234","Blah Blah", "Foo","Bar","","","",""
"foofoo","barbar","etc.."
Where ever there is a carriage return it signifies a new row and every comma separates a new column from another.My next step is to go into VB.net and create an array using these values and having the commas serve as the delimeter and somehow making the array into a table where the text files' format matches the array After that array has been created, I need to select only certain parts of that array and store the value into a variable for later use.... how to make the array and selecting the certain info out of it..
How do I go about doing this? I have currently made this code, but sometimes points are created on the boundaries of this picture box, which I do not want. I want all new random points to be within the bounds of this large playarea (picturebox). Foodarea is my big picturebox which i want all fruit to spawn WITHIN not outside on it's edges.

View 1 RepliesI have an array with 280 items in it. I only want 140 of those, so I want to pick them at random. So I need to generate a random number between 0 and the source array's getupperbound property. I think. Is there a more suitable way to pluck an item from an array. I wonder if there's a way to ensure that you don't choose the same item more than once. I suppose I could randomly sort the source array and choose the first 140 items, that would ensure I don't get a repeat item. But could be inefficient if the source array is much larger than the destination array, because I'd be shuffling more values than I need to shuffle. I suppose it's a sampling problem.

I am trying to get a random word in VB and was wondering if it was possible to do this through the internet some how? For example If there was a website that literally just contains random words (anything over 100 will do) and I could just select a random word from it? I can create random letters and numbers but I want a word that would be in a dictionary.
