This is what I'm trying to do: I have a listbox to display a list of costs that the user inputs. I want to use some kind of loop to add those numbers from the listbox sequentially, then display the total in a label.
How do I set up a loop (and what kind of loop is best) to pull the numbers and add them to a total? give an example of what the code might look like. I'm new to VB

I'm trying to create a for loop that will display the values (favorite programming languages) a user selects for a listbox.
So far I have this:
Dim selectedLanguages As String = ""
For intLoopIndex As Integer = 0 To languageListBox.Items.Count - 1
[code]....
So far, no matter how many items they select it will display a comma even if only one item is selected, example "C#,"However this is what I need it to do:
1. If the user selects one programming language than it should just printout the selected course with a period right after it. Example: C#.
2. If the user selects two languages it needs to have the text "and" between them followed by a period. Example: VisualBasic.Net and C#.
3. If the user selects three or more languages it needs to seperate them like this for example (again with a period at the end): VisualBasic.Net, C#, and Asp.net.
i want to convert text box inputs into a list box. i have 7 text boxes like; fname, lname , email, phone, etc
how would would i call those textboxes into a list box. also it it possible to make headers for the the listbox.
I have several text boxes that I will input answers into and I want them to catch the values if they are incorrect or correct.
Example: the user will input a Letter for the answer, A or a, and I was curious to how the correct input can detect if the answer is correct.If the answer is A B C or D then no message should display but when it's some other value this message will come up.How do I use true or false in this code?

i have created a simple form which takes some input from the user. Now, I want that the input should be saved to my harddisk and can be seen later as well. Can you please tell me how to save the inputs as a record on my harddisk.
I mean the first time the form appears, it has four options. All the four options will be a record. The next time the form is re-loaded, then the same four fields will have data for someother client. It should be saved as another user.
I have several text boxes which a user is supposed to input a numeric value and the program will use an array to verify whether the input in each text box falls within the numeric range allowed for that text box. So one text box will only accept number 3-7 and i'm supposed to create an array that will verify the input in that text box falls within that range. Personally, I would just do:
Dim intInput1 as Integer
intInput1 = CInt(txtInput1.Text)
If intInput1 >= 3 or <= 7 Then
messagebox.show("Input Verified")
Else
messagebox.show("Input must be a numeric value between 3 and 7")
End If
But this isn't what the assignment asks.

View 4 RepliesI am building a program where all the inputs (10) required from the user are asked on one form. Since it is not possible to let fields blank on the database, I would like to know how can I build an 'IF' saying that if all fields are full, then the database CAN save all the input. So that if there are any field blank, it won't save. I just dont know how to do the database condition. Thats all.
View 3 RepliesI'm currently trying to improve the speed of my program. Basically the user inputs min and max values for a, b, c, and d and a constant n, and then it tries to find the curve/line in the form a (x/b + c) ^ n + d. However for large ranges (1-100 for a,b,c, and d; total of 100 million values to try), it would take around 100 minutes at the current rate (approx 800k values/minute). I'm wondering whether I can further improve the speed. [Code]

View 11 RepliesIs it possible for you to loop a block of code until the user provides a valid input? Like, when I click the save button, the program will prompt the user for an integer value, and I would like to validate if the user has inputted a valid value. If the user fails to input a valid value, then the program will re-prompt the same message again until the user inputs a valid value. Eg:
If MsgBox("Add copies to this book?", MsgBoxStyle.YesNo, "Adding Book Copies") = MsgBoxResult.Yes Then
Dim CopyQty As String = InputBox("Amount of copies to generate:", "Add Book Copy")
If IsNumeric(CopyQty) = False or (CopyQty < 1) Then
