I cannot figure out how to incorporate the number of days into the input box then get it to loop and count the number of times the User inputs in the number of days. Then I have to incorporate it into the equation to get the total distance D = MPH * Hours. What I have right now wil not count up the number of days and locks up after I input one number and will not add anything to the listbox. Because I also have to make sure that they cant add nonnumaric values and the number of hours per day cannot exceed 20. I have put things in and taken them out but it has been 2 days and I am lost now

I've been working on some code to add together input from an input box to make a string and display it in a message box. I've put the code in a loop so that it will add all input into the string until nothing is entered in the input box.
Dim stringInput As String
Dim message As String
Do Until stringInput = String.Empty
[Code].....
All I get is just the last input entered to show up in the message box and none of the previous entries. How do I get all the input to be added together and show up in the message box?

I have a data logging application that stores data in a table in a MySQL database. Data with a TimeStamp is logged into the table anytime the data from the sensor changes. This means that there maybe 2 seconds between data points or there maybe 20 seconds between points depending on how the data is changing.
When I need the data I have 2 dates and use this command to fill a table..SELECT FROM myTable WHERE timeStamp > date1 AND timeStamp < date2 This gets all the data that has a TimeStamp between the given dates, but in most case the first date in the returned table will be after date1, so I need to get the data from one row before the date returned in the table to know what the data was at date1.How can I get the data row that immediately precedes the returned data set?

I have a program for school project that has input fields for Name, Address, City, State and Zip. I need to error check so that the fields are not empty.I have used If statements that check to see if the fields are empty and shows a message box if they are but if I leave the whole form empty and click the button that activates it, all the if statements go- one by one instead of pausing for the user to input the required data.How do I check for data and make the program stay there until the data is input? I have tried TRY/CATCH but it won't catch this type of error.
this is the

I have for ex. 5 names i table A in table B i have several rows with 50 names.. But i only want to pull out the records that matches the 5 names in table A! I never know the amount of names in table A so i need to pull out every record in that table..I guess i have to get the names from table A and put them into an array and then in the query get the records from table B that contains the data in the array.. I have tried, but no luck..

I have some code here that connects to my Mysql database. It checks your username and password and if your login was successful and it retrieves the phone number under that account. How would the SQL Query look like for retrieving the phone number once connected? Then how would I be able to display that phone number on a label?
