Getting Letters Instead Of Numbers In Extracting Area Codes
Jan 30, 2012
I'm brand spanking new to coding (as well as this forum). And I'm learning Visual Basic 2010 in School. Right now I am working on the following problem: "Use a masked text box to as a user to enter a phone number in a format as follows: (604)323-5819. Make sure you add input mask to the area code and phone number. Both the phone number and the area code are required. Then extract the area code and display it in a text box when a button is clicked." Here is my code, I've got it where I can input the number, and when the button is clicked (things actually appear in the text box!) however instead of getting the area code, I get "als" or alternatively if I put (0,3) I'll get "fals" I don't understand what I'm doing wrong or even where "fals" is coming from. Can someone please explain to me what I'm doing wrong? I've literally been at this since 4pm today and only just (midnight) able to get it to this point and I'm incredibly frustrated as to where these letters are coming from. [code]

This is my second post on this topic. I included all the code this time. In calculate click event the value is zero and I don't understand where I went wrong. My work is due tomorrow, if anyone can tell me why I can not extract the price from the string. What this program is doing is taking items from the stockListBox and adding them to the shoppingList Box then extracting the price from the shoppingListBox and adding the prices together.t a note- in public class I changed the string and seperated the price from the item, not sure if I was suppose to do that.lso, everything works except the calculate event.

I'm looking for some function to put together every possible combination of letters and number to create a string that is 14 characters long. I have found ways to make every possible combination of letters and numbers seperately. However, I've never run across anything to come up with them together. Every string created must contain letters and numbers.I just have no idea where to start on this one.

I am trying to extract numbers from string text. e.g. 1 day (8 hours)' I need the one and the eight integers pulled out I would like to extract then store each number separately for use later. I am aware of techniques to count string text, but not pulling certain information from it.

im a student still learning and im stuck. im writing a program that returns the ip address, splits it in to parts, and now i need it to return a string of letters for other parts to use. EX.
ip address 127.0.0.1 will look like ABG.XXX.XXX.XXA
( i would like to set 0=X so it is easier to pick out the actual
numbers)
I am able to split it and display each part and rewrite it to textboxes without the "." but i dont know where to begin to change the numbers to the letters i need.

I'm on VS 2008 I have one form contains many textboxes,when I write in one textbox (UserName) the letters and numbers should distribute to the other texts where each textbox has only one letter or number from the original text to get them ready to be encrypted.
What code I can use in text change event that takes the whole text and throw it in the other textboxes so each textbox has only one value ?

1. allow the user to specify a folder in which to find a specific text files,
2. to read a few specific numbers within each of those few text files, (eg. in txt file A, #A = '1', in txt file B, #B = '2', etc)
3. place those numbers into multiple comboboxes, (eg '1' into CB1, '2' into CB2, etc)
4. allow the user to change the number from the combobox drop down list, (eg CB1 change to '2', CB2 change to '1', etc)
5. Click to overwrite the old numbers in the text file with the new numbers and save the text files
My main problem is no. 2, how do I read a specific string in the text file and display it in the combobox?(Win XP, MS Visual Basic 2008 Express Edition with sp1)

I have a textbox which controls the interval of a Timer control. How do I filter out letters? Is it possible to restrict entry to numbers only (like if you enter a letter or a space, nothing happens)? Is there a property of the textbox that can accomplish this?

What I am trying to do is create a form with a button and a list box. When clicked the button will generate a list of 3 or 5 characters that have alternate letters and numbers...eg.
q2h
a6j
z4p

[Code].....
To complicate things a little, each combination needs to be different, ie. randomised but still according to the 'letter,number, letter' formula. There are plenty of examples of randomising strings such as passwords but I cannot understand how to achieve the above.

I have to (for class) make a program that generates a safe passwords for people to use. My teacher wants us to make the passwords vary in length, include numbers, letters and upper case letters. I've been able to write code that prints out a random string but it includes unrecognized characters for most passwords. How would I write the code to create a random string that has parameters? (in this case upper case lower case letters and numbers).

How should I use linq to sort my data when my data contain both numbers and letters? For example my current linq
Dim MyQuery = From c In XDoc.Descendants() _
Where c.Attribute(Y) IsNot Nothing And c.Attribute(Str) IsNot Nothing _
Order By Val(c.Attribute(Y).Value), Val(c.Attribute(X).Value) _
Select Str = c.Attribute(Str)
Returns something like the following
13
167
172
231
44
49
Which is not what I would like it to be...
The output should be like the one below:
13
44
49
167
172

The app uses several forms to let the user enter information. In each form the info is entered into textboxes and dealt with elsewhere when the "Enter" button is clicked. A lot if the info entered is used in calculations and so must not contain alpha characters, only numbers. What is the best way of examining each entry and identifying any that are not numbers, so that I can ask the user for a correction with a MsgBox?Prevent Users Entering Letters Instead of Numbers?

I made a small license generator app with a datetimepicker, a textbox and a button on the form. When I ran the app and clicked the button to generate a license I got - 16DDD-06DDDD-09DDDDD, and each subsequent button click would get me a license with a different generated character (16444-064444-0944444, etc...).
I thought this was unusual as it should be generating a random character not a repeating one, so I stepped through in debug and the characters generated were random (161g2-06T5ip-0957H9k). I thought perhaps that I needed to seed the value with Now().Milliseconds, no luck, that still resulted in repeating characters. So I tried sleeping the thread and that generated the random values I wanted.
