I have several text boxes I need to validate. I am not understanding how to validate in Visual Basic 2008. So I deployed standard If Statements to handle bad data. I am having two problems.
Lets say the user entered wrong data, example, numbers; an error message is displayed. The text boxes cannot contain numbers, be left empty or contained characters, like !@#$. The problem is if the user enter text, and then entered a wrong data again the code does not work or display error message. How can I make the conditions so that they throw out error message even if the user had previously entered good data.
Another example: If the user enter good data in text box 1 and bad data in text box 2, the error message does not work.
Finally, how do I filter out characters to allow only text. Is there a way to use this code on multiple text boxes with out writing the entire code for each form control?
Here are the conditional statements.
Private Sub btnDataSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDataSubmit.Click
If IsNumeric(txtDataEntry.Text) Then
lblErrorDisplay.Text = "Invalid Name!"
lblErrorDisplay.BackColor = Color.Red

This is in MVC3, VB.net. I'm looking for an easy way to validate a users input data into the editorfor field.
I thought I postet this yesterday but I can't find my thread so if this is a duplicate please point me at the original one. Background: I need to create a user account and Modify it's registry before the user logs on the first time. Creating the account is done by using the Winnt provider (works great). To create the profile I'm trying to use Process.start to launch a process as the newly created user. With the use of loaduserprofile property the users profile gets created and i can do my regwrites without problem.

Getting some errors with a loop. It's a log-in app that has username, passwords & account type stored in a SqlCe database. I would like it to sync with a larger database for updates that has not been made so i left it out but I have started to make a loop that would connect it to the larger DB and if connection failed would try a set number of times before stopping the program. I'm coding this project with Visual Studio 08 pro
Dim conndb As New SqlCeConnection("Data Source = |DataDirectory|\Mydb.sdf")
Dim x, y, z As Double
x = 1
y = x + 1
