BeforeInverse= ((2nd.Text ^2 + 3rd.Text ^ 2 - 1st.Text ^ 2) / (2 * 2nd.Text * 3rd.Text))
Calculation.Text = Math.Acos(BeforeInverse/ Math.PI * 180)
The above is using the cosine formula which has been rearranged to solve for the angle. When i calculate, it comes up with NaN and i'm not dividing by 0. What does NaN mean and is there an error with the above code?

how to code the "from" portion when an email via vb.net. I could easily do "mm.From= email@domain.com"...but for this project it needs to be sent automatically depending on which user is entering the information. So I have lets say a group of 10 users, anytime a specific user sends in an update on a project form, the email is sent to the manager from the person who it's been updated from. Any suggestion? They all have specific ID's. How would I code it to where I could get the program to find them by their ID and then get their email address from their ID?

I have a CheckBoxList on my page that isn't behaving very well.The idea is that once the submit button on the form is clicked, the app should clear the database table of all rows pertaining to the specific user and then re-insert new ones based on the user's CheckBoxList selections.The problem is that regardless of whether or not any (or all) items in the CheckBoxList are selected, the app keeps getting Selected = False.[code]I'm aware of the potential for SQL Injection here. I'll be going over to using Parameters as soon as I have the loop working.

I am new to <acronym title="Visual Basic">vb</acronym>.net but i have been writing my first Application. The application is a customer database. I have a contacts form and in one of the fields the user puter their date of birth. Alk data is writen to a SQL database. I also have a listview on the right when the application lauches. I want this listview to show birthdays that are coming up in say the next 30days. This is so the user can send a card/ present.
Here is my SQL Update
"update Contacts set contactname='" & tbName.Text & "', PostalAddress='" & tbAddress.Text & "', PhoneNumber='" & tbPhone.Text & "',MobileNumber='" & tbMobile.Text & "', Email='" & tbEmail.Text & "',DateOfBirth='" & Format(dtpDOB.Value, "dd MMM yyyy") & "' where contactID ='" & localContactID & "'"
Then my listview has the select
"SELECT ContactName, DateOFBirth, ContactID FROM Contacts"
I did try
Dim todaysdate As DateTime
todaysdate = Date.Now.AddDays(+30).ToString("dd MMM yyyy")
But it is looking at the YYYY and for it to show evey year the YYYY has to be ignored.
make a window change instead of a whole new form coming up(EX: when I press the next button, the layout of the page changes, but no extra forms)Well, If it is not worth it, it is not fun - you say programmers are boring but i say they are worth it.

View 7 RepliesI've created a program that allows a user to input numbers and then outputs the highest and lowest number when the user is done (the user indicates this by using a sentinel value of -99). My only problem is that it keeps putting out the numbers reversed (largest as smallest and vice versa).
The code is below.
Module Module1
Sub Main()
'Declare Variables
Dim number, smallestNumber, largestNumber As Integer
'Get numbers from user

Is it a no-no to have a module within a module like I do there? So far there is no mention of such in the book but I can't find an example of it happening yet either? The instructor wants modules to perform the input and return of information and the only way I could figure out it doing both of those things (rather than using the main module for user input) was to call the module that figures hi/lo within the module that asks for the numbers. I'm really unsure on this part.
I am trying to write a program that captures log information from my Cisco 5510 firewall. I have a service working where it will perodically write text to a file.

I need to know how can vb capture that traffic and write it to the log file. I am a beginner to vb.net so please be patient with me if it seems like I am asking too many simple questions.
