How can I join more than one integer number to become one integer (Long) number?
e.g. 2, 3, 2 and 5 = 2325
123, 7 and 2 = 12372
10, 0, 5 and 1860 = 10051860
0, 10 and 450 = 10450

I am trying to create double and number format cells in excel using NPOI library. I used code like Dim cell As HSSFCell = row.CreateCell(j) cell.SetCellValue(Double.Parse(dr(col).ToString)) In excel numbers are aligning right but when I check format it is showing in "General" then I changed my code to like below

I've just begun using VB2008 Express. As practice, I'm trying to create a simple program that allows users to practice their basic arithmetic skills. I've just run into one hiccup.
I have a procedure that generates random numbers for the program to spit out as text that the user will then do arithmetic on. I'm trying to create a loop that checks, in the case that a radio button selecting division practice, that the potential quotient [code]...

What i'm trying to do is compute whether an integer number is prime or not. The program performs this analysis for all odd numbers from 3 up to an input integer limit, for example 100. If the integer in the range 3 to limit is prime, a message stating so is printed. Otherwise, a message is printed that lists at least one other integer divisor. The output for each analyzed number consumes one line of text.
A sample output is shown below:
Limit is 100:
Number 3: is prime
Number 5: is prime
Number 7: is prime
[CODE]...
I understand I need to use loops, boolean functions, vbmath(), strings and multi-line out via concatenation. So I can put this is words how I think it should be done but not so great putting the code together
Test all integers up to the SQRT of the number (100)
limit = math.sqrt(100) + 1
Followed by 1 For statement
For c = 0 to 100 step 2?
And an If statement
If ......
result = false

I know there has to be a simple way to do this but I'm not sure how the syntax would go. I need to generate a random number from 1 to 99. How do I do this? I have my attempt that failed below:
Private Sub LoadBoard()
Dim mynum As Integer = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99)
Storage.Slot1 = mynum(Int(Rnd() * 10 Mod 99))
End Sub

How can i format a double number to be like a integer?
for example:
i want to 12.34 to be rounded and displayed like 12 not 12.0.
because when i do String.Format("{0:n0}", 12.34) the number will be displayed as 12.0

I am loading data into excel from datatable using LoadFromDataTable method then changed cell format to integer still it is showing error "The number in this cell is formatted as text or preceded by apostrophe". cell was showing to right side only and number format only on cell property.still I am not understanding why I am getting this error??.
Dim wsManufacturing As ExcelWorksheet = pck.Workbook.Worksheets.Add("Manufacturing")
wsManufacturing.Cells("A1").LoadFromDataTable(dtManufacturing, True)
Using col As ExcelRange = wsManufacturing.Cells(2, 2, 2 + dtManufacturing.Rows.Count, 2)

I am writing a VBA code for testing different combination of 24 variables and recording a result which corresponds to each combination of 24 variables. so I have an equation with 24 variables and one result. In excel I have one column which contains the 24 variables and the column next to it contains a figure which shows the result. what I need to do is to write loops to change the 24 variables between 1,2, and 3 and then record the result of the equation for each combination of 24 variables. I have written the loops (24 loops) and can record the result for each combination, what I have to do at this stage is to record the combinations which relates to each result.
As there is only one result for each combination of 24 variables I was wondering whether I can tag each variable (in each cell) in a way that in the final sheet in the cell next to the result cell I can write for example 111123123111233311121232. This means that after each loop I am taking the values for each variable in 24 cells and put them all together in one cell in the final sheet. These variables are changing in each loop, the label should change as well after each loop so after the completion of the code I can find out which combination relates to which result. I have tried to define an array or matrix but I couldn't fix the problem. This is the input sheet (the code changes the values in the cells in A column after each operation)

I have a program that will round any numbers I give it regardless of the data type I set (I've tried double and decimal) before it saves into the DB. I'm using MS access for the DB and I've set the data types in access to Numeric Double, Numeric Decimal, and Currency and all with decimal places set to 4 -- all to no avail.
What I do know:
1) The textboxes on the form accept the number value as I enter it and after I hit save the value displayed is the same as the number that I entered. However, once I query the database again for that entry the value has been rounded up/down to the nearest integer (whole number). For example: I enter 1000.50 and hit save. I search for that same entry and the value is saved as 1000. If I enter 1000.51 and hit save then search for the entry it shows the value saved as 1001.
2) I can store the desired value directly into the DB by manually entering it. When I search for that entry from within the program it displays the correct amount. HOWEVER, if I try to change the amount and then hit save I get a concurrency violation.
I think that it may be a setting somewhere in the program that doesn't allow for decimal places but I've search everywhere and I cant find anything.

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 read some of the other posts on this and seem to be a little different than my situation. Trying to print out some reports into an excel document on the clients machine - of course it works fine on my local (heard that before right). I went in and set my references Ms.Office.Core and Ms.Office.Interop.Excel to 'Copy Local' = True so the .dll are in the servers bin folder.
