VS 2008 Numeric Input Format?
Aug 25, 2009Is it possible that a user input to a textbox like '12500', but vb shows it
'12,500' at the time of input.

Get The App To Accept Numeric And Operator Input While Ignoring All The Alpha Input?
May 10, 2010I am writing a calculator app in VB Express 2008. I'm trying to get the app to accept numeric and operator input while ignoring all the alpha input. In other words taking input from the numeric keypad and the top of the keyboard and ignoring all the letters.
Here's the block of code I have so far:
Private Sub TextBox1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
If (e.KeyCode >= Keys.D0 OrElse e.KeyCode >= Keys.NumPad0) And (e.KeyCode <= Keys.D9 OrElse e.KeyCode <= Keys.NumPad9) Then
Select Case e.KeyCode

I can't get vb to recognize the above code it seems to skip right over it. BTW, is 'Keys.Crsel' the same as the caret '^' symbol?
VS 2008 - Input String Was Not In Correct Format
Dec 23, 2010When I attempt to read my Xml file when using a schema file I get the following error message:

VS 2008 Input String Was Not In Correct Format?
Nov 15, 2009I am building a program for my CINS-113 class where it allows the user to enter a number 1-15 in a masked text box and then hit OK and it will display that number in a ListBox as such:
Say they enter 1...
1 X 1 = 1
1 X 2 = 2
1 X 3 = 3
...
1 X 12 = 12
I have gotten everything to work great, but when you enter anything but numbers 1-15 it properly provides a message popup telling you that your entry is basically not the right value, but then I get a build error that says "Input string was not in correct format" and it highlights my line: "intInput1 = Convert.ToInt32(strInput1)"

[2008] Checking Time Format From Textbox Input?
Mar 8, 2009I have been trying to check if a user has input a specific time format into a textbox.For example
1- User enters time in hhmm format
2- Checks the input
3- If wrong, MessageBox.Show("Need hh:mm time format")
I have only used IF statement with IsNumeric to check for number input but was unsuccessful with various attempts I can think of for checking a time format as I need Option Strict On and have the following error: Option Strict On disallows implicit conversions from 'String' to 'Date'.Is there a way to like check if the hh:mm has the ":" separator too?

Page Calculator - Converting Input To Numeric Variables
May 16, 2009Description of Program/Events. I would like to come up with a number generator that takes the Total number (for this example I'll say 20), divides it by 2, and does alternating additions so the end result will generate a list like this:

Sep 17, 2009I'm having an issue with a page I created that was working fine two months ago. Nothing has changed in structure of the SQL tables and I have even done an insert within SQL to the table and all works fine with SQL. So the problem lies within the code. I'm getting this error:
