I am trying to write the code for a conference:
1 person costs $695.00
2-4 people costs $545
5-8 people costs $480
8 or more costs $395
If the company has been before they get a 15% discount and no company can have more than 16 people. The program asks that the user enters valid data.?? (error msg boxes)
Using VB2008, Access
I have 2 fields defined as date/time (short date).
I need to store dates fields which may at times be blank (null), how do I go about that?
I tried using:date.minvalue and that stores the value of 12/30/1899. I would like the field to be blank until the user enters a valid date.
I have a login form that I made. The user enters a username in textbox1 and then enters a password in textbox2. The user then hits the submit button (button2) and from there it works beautifully. The problem is, I would also like the user to be able to hit the "enter" key after they fill out the password textbox (textbox2) and have it be like they pressed the submit button. When the user hits enter right now, the form hides.
View 4 RepliesWell, I have a form called customers. Login form and mainform.
So my clients want to have an option that explains this: If a user enters information in the customer form, then that information has to be confirmed by admins panel.
Get me well. When application program loads with a limited user, I set some buttons hidden so that only admin can see it when they log in. so in that case, users are not capable of inserting anything in the customer form.
But this time they want users to insert information then the information goes to administrators to confirm the information...if admins accepts the information, then information is then goes to customers table in database. If they don't confirm it, then that information will be ignored.

View 9 RepliesOk so i made a program where the user enters 3 inputs in a 3 textboxes (First Name, Last Name, Bday) and when the person presses enter a check list is made under the checklistbox with the Lastname.

View 11 Repliesso my program takes what the user enters into a textbox and searches through the data i have stored and if it matchs one of the peices of data it displays the apropriate data to the user. This all worked fine till i changed the textboxes to be added dynamicly to the form when it is load and i put all textboxes in a collection. So now when the text is sent to the search sub it sends the data over but always returns that it didnt find a match. But if i go into the search sub and just tell it what to search for automaticly it finds it no problem.

View 1 RepliesI have to make a basic program that: Create a program with a simple interface that
1. Asks the user type his/her email address into a textbox.
2. When the user clicks the "Evaluate Email Address" button, one of two message boxes pops up: "That is a valid email address!" with an "Information" icon, or "That is an invalid email address!" and on a second line, "Please retype your email address.", with an "Exclamation" icon
3. To be considered valid, the email address must -include an "@" symbol, and -it must end in either ".com", ".net", or ".org" or ".edu" (I don't know how to check a string and test if its last four characters end with any of these and make it say not valid email address.

My code works correctly if I do not have the DO WHILE statement, however we are suppose to have it loop. Which it will continue to ask for the salesman's name, code, etc. but when the user enters the name "eugene" the program is suppose to calculate and output the total monthly sales and the total commission dollars. What is happening is that when a user enters "eugene" the program is not recognizing it to do what it is suppose to do(calculate and output the total monthly sales and the total commission dollars) I am stuck and need assistance on how to make it recognize eugene. I am also having trouble with trying to figure out how once eugene is entered to tell the program to add the salespersoncommission and monthly sales of each case to get the totals to output to the user. Can you add the cases?

I was developing my own project in the university so what i am stack is to have save button which firstly validates what the user enters the form. for instance if the user skips the text fields, i wanted to restrict the user to fill all the form and when he completes, the save must be accomplished.

I've been using KeyPress to help limit what the user enters into certain textboxes. e.g. here's my code for a Phone number. It only allows for numbers and dashes: [code]It's all working fine; however, the thing I hate about using it is that when ever have to do debugging of the screen, for each keypress into this textbox, it goes into debug.I'm wondering if it's possible to do something similar when the user clicks the save button. Has anyone done any type of validation like this?

I have a search box on a site, that searches for recipes. Each recipe has a what you're making image, a title, and type(dessert, lunch, dinner).

Now I'm using VB's ASP.NET MVC3 w/ Razors for the site and I'm trying to get some auto completeness going on when the user enters text.
What should happen is when the user enter text, it will call an ActionResult in the Search Controller. Which queries the DataService and puts all the search results in a model. With that model I return a PartialView, results, with the Model included.[code]...

I have two textboxes on the screen. They are used for startdate and enddate. If the user does not enter anything in the textboxes I pass nothing (VB.NET) to the webservice. When the webservice receive it on the other end it shows the value "#12:00:00 AM" which I think is the default for the datetime field. Anyway, now I do not want to pass this value to Stored procedure since it will not work. How can I check before sending values to sproc that the value is not the default datetime.

You will need to make use of the RichTextBox, along with concatenation to make the output format correctly within the box.When you have created the working program, document it properly by printing out and annotating the code to explain how it works."

I'm playing with XML, DataGridView control, DataSet and DataTable. [code] the user can edit/add records via DataGridView control. So, when the user enters a string value where it is expected to give an integer value(first column and third column), it would give a big error message. Instead of showing that, I would like to apply custom validations.
View 3 RepliesI'm using a bindingnavigator. My datasource has the column "key1" marked as unique = true. The user presses the "+" button on the screen. A blank form is presented as expected to allow entry for the new record. The user enters "A" in the "key1" field, "A" already exists in the dataset as all records have been returned by the fill command of the tableadapter, the user then, without attempting to click the save button, clicks in the "PositionItem" textbox in the bindingnavigator. They then enter a number (say "1" for instance to go to the first record in the bindingsource), when they press enter an unhandled exception of type ContraintException is thrown. The exception is expected since the Constraint is not met. But how can I handle this exception, or how to I reimplement the code to do the work of the "PositionItem"? I know how to override the "movenextitem", "movepreviousitem", etc.
