I have two masked text boxes that holds Phone Numbers and Zip Codes.Since they are Masked text boxes and are set not to allow characters or letters, the user must enter numbers.However, how do I add a message telling the user to enter number and zip code since there is no prompt?I don't need to validate the numbers just to add an error message if it's left empty.

I need designing a Windows based computer program that will allow a user to enter some number (n) and a choice of a count up or count down for that many numbers. So for example, the user enters 5 as their number and selects the count down option, the message box displayed would contain the message: "Here are your numbers: 5,4,3,2,1,0"

I need to retrieve multiple objects from an external system. The external system supports multiple simultaneous requests (i.e. threads), but it is possible to flood the external system - therefore I want to be able to retrieve multiple objects asynchronously, but I want to be able to throttle the number of simultaneous async requests. i.e. I need to retrieve 100 items, but don't want to be retrieving more than 25 of them at once. When each request of the 25 completes, I want to trigger another retrieval, and once they are all complete I want to return all of the results in the order they were requested (i.e. there is no point returning the results until the entire call is returned). Are there any recommended patterns for this sort of thing?

Dim query = (From p in Parent _
select _
p.ID, _
Tags = String.Join("|", p.Child.Select(Function(c) c.Tag.TagName).ToArray)).Take(100)
In the above query, when using Take to limit the rows returned, a separate SQL query is executed for each row to return the 'Tags' field. If I remove Take(100), a single query to sent to Sql Server.So, how do I limit the number of rows returned, while preventing a new sub query being executed for each row?

I've made a lot of progress on my project. Only question I have now is how do I limit a textbox to only allow users to input numbers and one decimal point? The point of the decimal point is to make it currency. So if the answer of my calculation is 56.56566 I only want it to be $56.57.

I have a textbox called textbox1. I wanted to limit it to only two characters, so I added the code TextBox1.MaxLength() = 2, however this textbox is for user input and only want to allow numeral values 0-99. And if the user entered a non-numerical value an exception would occur so I need help on to handle that.
