VS 2008 Add A Message Box Or Alert To A MaskTextbox If The User Enters No Numbers?
Mar 21, 2011
I have a MaskedTextbox which takes Us Phone numbers. Using The MaskedTextBox ensures the user can enter only numbers and the number gets formatted right.
Here is the problem I am having: How do I add an error message if the box is left empty? I am not trying to validate the number, just need a way to add: "You forgot to enter a number." Can I add this to a MaskedTextBox?
How do I add a message box or alert to a MaskTextbox if the user hit submit without entering numbers?

I am making a program, where the user enters 6 numbers in 6 different text boxes, and it displays the larger of those 6 numbers. But I also want to make it where if the user enters a string value (like S for instance) in the text boxes, it gives an message and says "please enter the numbers again" and the user gets to enter the 6 numbers again. But when I do try to do that, it gives an error message saying conversion from "w/e the user entered" to Double is not valid. If the user just enters the numbers, it works fine. However, I am trying to make it if the user does enter non numeric value, it gives a message window and the user can reenter the numbers again.
Here is my code Example
CODE:
This is where I am trying to use IsNumeric to show a message if a user does not enter a string so the user can renter the numbers again, but when the user does enter a string value (say in textbox 1) it gives me an error message saying conversion from "S" to 'double' is not valid.
CODE:
Then right here this is where I have my series of ifs statements, this part works fine, it displays the largest numbers of the 6 textboxes every time. Error free.
CODE:
And do this with variable number 2, 3, 4, 5.
I know there are easier ways to do these with arrays and stuff. But I am not there yet. I am still learning about ifs and stuff.

I am writing a program that has to print an alert message in a textbox if the user inputs invalid data. Invalid data would be a negative number. The textbox is the same textbox as the result would be in provided they input valid data. Here is what I have but it will not print the alert.

I am wanting to allow a user to enter a number and depending on what number is entered, it will allow that many entries. For example, if 5 is entered, the user has to enter 5 numbers. Those 5 numbers will then be added together.I 6 is entered, 6 total numbers will be added.I was trying to do this with a for next loop but I wasn't getting anywhere.

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.

I'm using a series of nested if/then/else statements to make sure a user enters information into each text box or chooses a radio button. What would i use to say if no text is entered in textbox1, then ... also what would i use to make a sure the user choose one or the other radio button? for example i also have a combo box, i used "If SubjectComboBox.SelectedIndex <> -1" for the if statement.

I have a vb.net (VS 2005) application which downloads files from my webserver and shows its contents to user. And I make files at my end and upload files to webserver so that the application and download & process it. This happens at fixed intervals. Now I intent to send an instant alert (or message) to users who are using that application. For example: If I type a message and send "Hello everyone" then all those people who are currently using that product should get a popup with this message. My webserver is a hosted on a unix based system. It enables me to show html content and post files & stuff online.

Dim success As Boolean
Private Sub Save_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Save.Click

Normally I just redirect to a custom error page in on the Application_Error event, but I have a specific error for which I'd like to display an alert message while the user is still on the page which triggers the error. How can I make this happen?
I'm open to a modalpopup or any other type of error message, I just want to ensure the user stays on the page where they encounter the error.
This is in reference to this thread: [URL]
Here is the code I'm currently using:

I have a problem where I have maskedtextbox's for Time only that do not show correctly in the datarepeater. Outside the repeater they are fine. In the datarepeater it shows the date instead of the time but in the masked format.
For Example:

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?

Well, 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.
am using vb.net 2008 with sql server database.

i'm currently using VB.net 2005 with an Oracle 10g db.1. Alert the Admin by displaying on the main page a list of users who are due for re-certification if there are any. - I've managed to do this except my date calculation for the alert is wrong. When a user is certified say on 25-06-2010, they will be up for re-certification in 25-06-2011. I need my program to start alerting the Admin a MONTH before the user is due for re-certification. So basically start the alert on 25-05-2011.Currently this is my logic in VB.
Reason = Get value in Reason field (If this field is not empty, then don't raise alert for this record)
Renewal = Get the re-certification date
Sysdate = Get current system date
[code]...
Alert the Admin via email - I've managed to create an email (stored procedure in Oracle) that contains the skeleton. I say skeleton because althought the mail executes fine, I've not managed yet to include the list of users due from the db. I created a Curser and dumped my results in there, but not sure what to do after that.

I've watch the videos on asp.net and I've looked online and have found nothing.
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).
All of these items are in a DataService, which I can query against and get a list of the items they are searching for.
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.
