i have a dice program that will find the random numbers according to user input as regards dice and throws required. My problem is when i have to display all the values in a listbox but in a horizontal type, were if a value came out more than once it displays the number and a bar for each time it come out and also at the end show the count of the times the number came out, to have a better idea the final chart needs to be displayed in the following format in a listbox as in the long run the program needs to run in a web application, but i am writing and testing in a window form application, then i will transfer to web application and use session variables and timers to control the output and the graph.
My code till now is that i have a class were a roll dice method and a similar values method are kept and from the form in the roll button these two methods are called and the results are shown in two listboxes one for how the roll dice random numbers with duplicates is shown and the other listbox displays only the numbers without duplicates.Also another method for the graph is in the class clsNDie but it seems that i have something wrong it this area?

I am having the following problem with a chart displaying a value that is heldwithing a variable but 10 times lager. But this is only happening in my programfor a user that is located in the Netherlands.If I run it from the UK or other people run it from other countries the valuesare displayed correctly, it only seems to be a problem for this one userin the Netherlands.I have checked my code and all is correct and there are no Multipliers added tothe value.To show what I mean see below, as I do not have the code to hand as I am currently at work.
I have to create a cafeteria survey application. Twenty students were asked to reate, on a scale of 1 to 10, the quality of the food in the student cafeteria, with 1 being "awful" and 10 being "excellent." Allow the user input to be entered using a ComboBox. Use an integer array to store the frequency of each rating. Display the frequencies as a bar chart in a list box.
I can get the comboBox and everthing, but it's not displaying the bar chart.
Here is my code.
Public Class Form1
'String array stores ratings Dim ratings() As String = {"1-Awful", "2", "3", "4", "5", "6", "7", "8", "9", "10-Excellent"} Dim studentCount As Integer 'number of student ratings entered Dim frequency(9) As Integer
I have a chart in Excel that I'd like to use a subtitle on. There is no SubTitle Property on the chart object, so I looked in the Excel User interface and found that you can only create a sub-title by using a text box. The text box looks like its associated with the chart, not the worksheet, so how would I access that text box from code?
I bound datagridview to bindingsource. The bindingsource has its datasource a collection Called Rates which is a collection of Rate items. The rate object has a property called VALUE. I need the user to be able to edit different values for the collection; However, on the datagridview, i need to keep displaying on one column called OldValue the existing Rate value before the change while allowing the user to edit that value in a second column called NewValue.
In other terms, One colum OldValue will keep the existing values from the DB before being edited by the user, this column OldValue is readonly. Another column NewValue will display, the 1st time, the old value from the DB (similar to OldValue when we do the Fetch from the DB), but it`s editable column, so the user can modify each value in the column NewValue without overriding OldValue cells. For now, I bound both columns OldValue and NewValue to the same property VALUE of the Rate object,
i have a Chart made in visual designer in vs2010, with some points added like x=3,8,10 Y=2,8,4. Is there any way to extract value for example for x=5 ?
I can't seem to get this code to refill the chart with new dat. The first time it executes, all is great, but when I change the year(numericupdown1.value) it adds a new set of data points instead of re-plotting the original set.

I am working on simple handover process from one mobile station to other. I got three proposed results service disruption time, network entry time, connection set up time. I also have the result of these three as by using some conventional way and got improved these three delay results by proposed way.
Results are store in textboxes. Now i want to show graphically. E.g. I want to show conventional service disruption time on x axis and proposed service disruption time on y axis or vice versa. Let suppose I want to have a scale on axes from 1 to 3000 milliseconds. Then I want to show how purposed scheme is better. I am using VB.Net 2008

How to set up a Chart using the new MS Chart control. I want to be able to populate the data via SQL because the user will be able to dynamically change the values via drop downs. The format of the data will be the same (Qty, Time Period) but the Focus of that data will change. I'm honestly not sure where to start, I can draw the chart but I have no idea how to populate it with data via code so it can be changed dynamically. VBE 2010, and I'm hitting an AccessDB
Is it possible to create a plot from List(Of Decimal) values in Excel with VB? I would like to avoid dumping data directly into a table, then creating the chart from that. Here is what I have so far, but I am getting a data type mismatch when I try to assign .XValues and .Values to the list. Is there some sort of conversion that needs to happen to turn a list into a series?
Dim Series As Excel.Series Dim xVals As New List(Of Decimal)(New Decimal() {1, 3, 4, 5}) Dim yVals As New List(Of Decimal)(New Decimal() {2, 2, 2, 2})

I need to convert hex values aa 01 00 17 f4 2f (as contained in byte array FrameData) to display in a label control as AA:01:00:17:F4:2F
HexDump(FrameData(2)) converts the aa (which has been converted to Decimal 170) into 31 37 30 !
similarly I need to convert hex data ('02 00' contained in byte array FrameData) as 0x0200."0x" & FrameData(1) + FrameData(2) displays the data as 0x20. How would I convert the '02 00' hex data to display as 0x0200?
Normally I've been lucky to find someone who has had the same problem and applied their solution but after hours of searching I'm not able to find a solution to this one. I've got a FormView which is default mode set to Insert. When the page is loading I'm checking to see if the session variable which the formview datasource is set to has a value. If it doesn't I've coded in the onLoad that some of the controls in the InsertTemplate would be set to specified value.
I'm creating a game using vb.net and whenever the user inputs something to my program it displays the time and the time displayed until the user inputs something again the the time changes. I have my program display each individual timestamp but I would like to know if I would be able to save the values and all display at the end of my game in a new form.
The code I have is the following: (in timer1=tmrReadInputs): For I = 0 To 3 If (Convert.ToInt32(DataValue) And CInt((2 ^ I))) <> 0 Then lblBitVal(I).Text = "1" Else lblBitVal(I).Text = "0" TextBox1.Text = Trim(Format(Now, "hh:mm:ss tt")) End If Next I tmrReadInputs.Start()
So when the value changes from 1 to 0, the textbox displays the time. How can I save the different time stamp values? I heard StreamWriter can work but I keep trying that and it doesn't work
I got 100+ textboxes that display record values. Most of the textboxes display correct values but several textboxes doesn't. These are the same textboxes. And they only display wrong values if I edit a record for the first time. After correcting the wrong values in the textboxes the first time, they display correct values in succeeding editing of records. Tried to compare their properties and all but they are the same with textboxes that worked...

I am developing a form which needed to display 2 values from a combo . I have table Account with these fields Account_type, Account_name in this table. Even though I am saving only the Account_type in to a new table but when selecting from the combo, I want the account_name also display since the account_type is a code so that user would understand the mening of the acount_type. vb.net code that would display both the code and the account name to this. I used data binding to do this, it also displayed only the code.
