AutoComplete Textbox - Start Again When User Hits Enter

VS 2010 - Add One Textbox So The User Can Enter A Distance Measured In Feet
Mar 31, 2012I started learning vb 2010 over the internet for about an a week and got stuck on this assignment that I got from the internet
1.Add one textbox so the user can enter a distance measured in feet. Add labels as needed.
2.Add a button control which when clicked is converts the feet to meters (1 foot = 0.3048 meters), accepting floating point values and preserving them (no integer conversions) and display the output as shown next. 1 Points
3.Display the conversion result using a MessageBox (not msgbox) using this format: x feet is y meters, where x is the value entered and y is the result of the conversion to meters with up to 2 decimal places only. Then show an extra line of "Would you like to start another distance conversion?" and make the No button the default in the message popup and display the question icon.
4. If the user chooses Yes, cleanup the controls as in the Reset button. 0.5 Point
5.If the user clicks no, ask in another MessageBox if the user wants to quit.
6.If the user chooses to quit, close the window, otherwise no action is required.

Mar 28, 2012My homework assignment is to create a project where a user enters a password that must be at least 3 characters long with at least 1 number and 1 alphabet character. After that the password has to be encrypted so that vowels become X, numbers Z, and it reverses. For example, a password of CS2301 would be ZZZZSC. There's supposed to be Loops to extract 1 number/letter at a time and search for them in the string to validate, and I don't know what to do. The form itself has a Text Box to enter a password and a label to display the new one, and a Go button.
This is what my code looks like so far.
