Nov 7, 2011
How can i check the exact word in a sentence.even though it is a alphanumeric.
Example: I have a user define value of "hello! how can i help you?"Then it will automatically check if the user's input type the exact text.if not it will produce a said number of error.
Example:The user input a value is a "Hello. how can i help you." it will produce and error base on the input text of a user.
Error:3 the error is "H,<.>,<.>"

I am making a security app. It searches for personal data as email-addresses and IPs, but the code to search for a ip-address is not working right! My scanner should manage to read the ip out of ex:
"ufyukovgjhsui192.168.0.100tyugfk
uyfkj192.163.7ytigfkidf,tygfnhmyu6"
I made this code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim i As Integer = 0
Do Until i = TextBox1.Text.Count

Ive got a Form application in VB.NET.I have many text boxes on one form (about 20). Is there anyway to check them all at once to see if they are empty instead of writing out a massive line of code to check each one individually such as
If txt1.text = "" Or txt2.text="" Then
msgbox("Please fill in all boxes")

I am using VB.net to create a simple winform. I have the option to save the data I input on that form. I am trying to prevent the user not to save the data if textbox10 is empty. I tried the while loop but I go into an infinite loop. The code is below. The if statement gives the error but allows the user to save.

I've got a program and what I need is for a Timer (running in a different thread) to constantly be checking a TextBox for an entry that is similar to:Quote"(PlayerName)" has joined the server.Where (PlayerName) would be replaced with the players name in the TextBox. What I would need the TextBox to do after it has found this entry is to add (PlayerName) to a listbox. If someone can help me out this far then I can use the same code to get it to remove the player when they leave.Below is a picture of what it should look like inside the program.

I'm struggling with my computing coursework in college and I though My issue is simple but I can't get it right. I need to validate the text into a textbox and check that it contains ONLY alphanumeric characters, but it MUST contain both, not either numeric or alphabetic, but some of each.The textbox should store information about a Street address, that's why both the street Name and the property Number have to be input. Spaces " " and points "." should also be allowed.If it helps, something like "12" or "St. Davis Street" should NOT pass the validation checks, whereas "St. Davis Street 12" will do.I would like to get it done with regular expression as I've been using them throughout my work, but I don't mind other solutions.I'm using Visual Studio 2010 Professional, 4.0 framework and Visual Basic.

I am having trouble using an If statement to check to make sure the value entered in a textbox is a double. I was told to use double.parse to check this but I can't get it to work right. Anytime I run the program and type text into the textbox, it tells me the code is not right.
Here is my
Dim DblFahrenheit As Double
If TextBox_FahrenheitTemp.Text.Length = 0 Then
MessageBox.Show("No temperature was given. Please enter a temperature to convert.")
ElseIf DblFahrenheit = Not Double.Parse(TextBox_FahrenheitTemp.Text) Then
