View 2 RepliesText Phrase Identification - Determine Type Of Input?
Feb 22, 2009I'm trying to identify if the input of a textbox is non numerical, which cannot be converted to an integer/double for calculation. I do this by converting the input1.text to ascii, and looking at the value to determine the type of input. My question is whether there is any way I can analyze the whole input character by character? Asc() only gives the ascii value of the first character, but what if the input is "9W" etc? Such inputs will pass my character test, but cannot be converted to an integer.

MemoryStream Truncating Input - Replace All Instances Of A Certain Character With A Unicode Character?
Jul 10, 2009I am working on a sub that essentially needs to open a text file, and replace all instances of a certain character with a unicode character. I'm trying to do this by reading the original text file byte by byte, converting it to a character, and then either adding that character to a memory stream or writing the unicode character to the memory stream. Then I'm saving the memory stream to the original file.

VS 2008 Random - New Character Out Of The String And Then Remove The Character From The List Of Characters
Dec 12, 2010[Code]...
For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.

User Identification Lost After Login?
Apr 9, 2010I am trying to write a program where a user logs on to the system and then enters predictions for the world cup matches. I have created the login screen which searches the 'users' database for the inputted username and password - it works (kind of) in the fact that users are granted or denied access. After a successful login, however, the system seems to forget who's logged in, therefore any predictions entered cannot be related the the userID of the 'users' table.
Here's the code I have in the 'login' button of the login screen:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim connection As New SqlClient.SqlConnection
Dim command As New SqlClient.SqlCommand
Dim adaptor As New SqlClient.SqlDataAdapter
