Receive Upper Bound And Lower Bound Of A Range
Sep 20, 2010
Is there anyone who can tell me the code for the below? Receive a lower bound and an upper bound of a range. Also receive a number of random numbers to generate. You must validate
1) the numbers are integers
2) the lower bound is less than or equal to the upper bound
3) the number to generate is positive (i.e., > 0).
Generate this many numbers in the specified range and keep track of how many of each are generated in an array of counters. Once all the numbers have been generated, display in a List Box the number, the raw count data, and the percentage of how many times the number was generated displayed with two decimal places of precision.

i wanted to create a random number generator that iterates through a series of number between an upper and lower bound. say between 1 and 100. Basically I want the number generator to pick the numbers randomly and then display them until all 100 numbers are picked without any duplicates. so thats easy I can code that. But what I don't know is how to show those numbers in the order they are generated on a windows form. So i have basically a variable that I will let be changed 100 times (or however many times I want, I don't want their to be a size constraint just using 100 as an example) and each time the number is generated I want it displayed on screen (in a list or something not sure what. Hopefully some type of scrollable list) and each successive number also to be displayed in same format beneath it so that I can see the list in its entirety. What type of form control do i use for that? I could do messagebox.show for each iteration but then user is required to hit ok after each iteration and that would obviously be a bad idea if user selected a large number to work through. Anyways, code isn't exactly necessary just point me in the right direction, i.e.what control (if any) to use.how to format the change in data?

I have this code:
Module Module1
Dim x As Integer = 1
Dim y As Integer = 1
Dim arr(x, y) As String
Sub Main()
[Code] .....
And with it I'm trying to change the upper bound of array dimensions. But I get this error:"Index was outside the bounds of the array".

Alright, so I've got my program and it works, but I have to pump out updates every once in a while. If I can get it so the code will let me have my text file with any number of lines for my array, then I can simply send out a text file and update done.So here's what my code does:
Define a record of arrays, two items, a unicode string (Japanese/Korean text) and then an English translation for the text.I read in the file, it's one item per line, unicode string and then the translation.I have it preset with a defined upper bound for my array, but if I just took out the define and leave the upper bound as limitless, then it would work if I just updated the text file. Problem is, I don't know how to do it with stream.reader (I think that's what it is) because I learned a different way in school. I want to do something like Do While Not EOF with this, and loop it reading lines from the file.
Would it work if I change the array to no upper bound and then simply use Do While Not EOF with stream reader?

There is something strange going on with my datagridview.
I've a data adapter that fills the underlying data table from a database. Then I assign this datatable as datasource to the datagridview Then I add a row to the datagridview and immediately I need to update the table in my database (as soon as user leaves the newly created row).
At this moment I have more rows (+2, not +1) in my datagridview than in the underlying datatable (the new row doesn't exists yet in it so the data adapter .Update method doesn't write anything to the database).
When DataGridView's .RowLeave event fires the undelying datatable is not yet updated. I've a question - is this behavior normal?

Here is what ive got:
a1 = inputbox("YES or NO")
If a1 = "YES" Or a1 = "yes" Then
That's all we need to know. There are a variety of choices people could put in the input box:
YES
YEs
YeS
yES
yes
Yes
yEs
yeS
I don't want to do if a1 = "YES" or a1 = "YEs" or ... etc
Is there some way I can do:
if a1 = allcase."YES" then
Or something along the lines of that?

I'm currently using this bit of code to let only Y, N, and Backspace be typed in my textbox: [code] My problem is that when I debug, the "n" has to be capitalized in order for it to show up in my textbox and the "y" has to be lower cased. Is there anyway that I can bypass this to where it doesn't matter wether or not it is upper or lower case?

We are binding most of our text boxes and dropdown boxes to a BINDING NAVIGATOR (with a DATA SOURCE of a DATA TABLE).When the BN is clicked through the text boxes all change immediately.We need to use some non-bound controls as well.First one is 4 radio buttons that when clicked will change a single value in a DATA TABLE.What would be the best method to do this? Should I track when the CURRENTCHANGED event occurs on the BINDING NAVIGATOR.I'm thinking that I could trick this by BINDING the SINGLE FIELD to a HIDDEN TEXTBOX and when that textbox CHANGED event occurs mess with the radio buttons and visa-versa.

lambda - vb.net lamba expression to select all values between lower and upper values plus the next lower and upper value. I need some help with a lamda expression to get a subset of range of values. I have a lower and upper value, and getting everything between them seems easy enough, but I also need the next lower and higher value to be included. I can do each of these separately, but would like to do it in one shot if possible.
The range I need the subset from has 150 values. A small example would look like:
{8.206,8.206,8.201,8.196,8.193,8.192,8.189,8.174,8.171,8.171,8.166,8.163,8.157,8.154,8.153,8.14,8.131}
My lower value is: 8.16
My upper value is: 8.17
I need to get back: {8.171,8.171,8.166,8.163,8.157}

I've got a piece of code in a project (MyProject) that contains early bound object from a referenced assembly (We'll call it CommonAssembly):

now I have another assembly that is dynamically loaded because it is not present in all projects:

This question may be off-topic. If it should be posted in another place (even on another board) For some given curves (see sample below) I have to quantify whether the red dots in some regions of the curve are more dense at the upper or lower edge of the curve. Which algorithm might be adequate to perform this task? The curves are constructed from measurements. (No mathematical formula behind it.) Every data point has two dimensions: A value in the range 4000-7000 and a second value 0-255.

My overall goal is to add fake/unbound items to a listview control (for final HTML Table output reasons). This is a code behind solution. Users will not be adding items as it will be outputted in a rigid table.
I have looked at several examples and while this is easy for a dropdown it is not for listview.
The code below works without error, but my item is not shown on runtime. I think the class is not setting the item fieldname correctly, but I can't figure out the right syntax to fix it.
ColumnNameAList.DataSource = PeriodDataView
ColumnNameAList.DataBind()

I have bound an array of a class with 3 public strings.
When I run the form app and in the form load call I bind the array to the DGV all works fine and the DGV is fully populated. However, if I change an item in the array I had expected it to change in the DGV.. it doesn't. Or rather, it only updates if I click on the cell that should have changed.
