View 1 RepliesI have an object, say Order where if an error occurs, it raises the ErrorOccurred event. If I'm running some code in say, the codebehind for a .aspx page with an public Order registered as WithEvents and I want to check to see if an error has occurred before I run more code, how do I do this? I can't simply check theOrder.ErrorOccurred. Do I have to create a local boolean flag that switches over in the event handler (OnErrorOccurred)?
Example:
Public WithEvents theOrder As New Order
Public Sub DoStuff()
theOrder.DoSomething()
If theOrder.ErrorOccurred Then

View 3 RepliesThis is not a homework of mine and i had never tried ms access database with vb so i just gave it a shot. so this is my first time and i am just trying not asking anyone to complete my homework. I have been searching for this a lot on internet but couldn't find a solution to this so i decided to ask this question here.
i have this sql code. what i want to do is that create a basic login form where users puts it's username in the UsernameTextbox and Password in the PasswordTextbox. If the the information match then a message box appears saying that the user is valid and if the information does not exist, a mesage box appears saying the users is not valid. now everytime i execute(run) the code, i come up with this error: Syntax error (missing operator) in query expression ''UserName' = 'Admin' 'PassWord' = 'testing123''.
The field names(UserName, PassWord) are also correct they are same as in the database. the information put in the username and password textbox are correct and they match the information on the database. But i dont know why this error comes up.

View 17 RepliesI'm connecting to a MySQL database using the MySqlClient class. When I try to fill a fill a Data List with the Data Set I get an error:#42000You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax

The connection works fine, and I am able to grab values; but I cannot fill this Data List.
I need to validate that a user doesn't leave the name field blank when they add a record in a datagrid. See code below that I wrote to accomplish this. It works fine if the code is under the 'saveitem' event. However, I want to check it each time a row has been entered (the user may add several records before clicking on the save button). I tried putting it under the 'Row Leave' event but apparently that event "fires" when you click the add button and throws up the error message immediately. I thought about doing it on 'cell' leave but then could not figure out how to determine which cell column you are leaving in order to check the appripriate field.[code]...

I am having a problem with this code. I have used this code before on other apps and it works, but I don't have a clue as to what is going on here.
This is the whole event. I get a runtime error msg thats says "Syntax error(Missing Operator) in query expression"
I think this is Legacy SQL coding but I don't know how to make it better.

Basically, in my Tcp Library I'm working on, whenever the system is told to "Stop", the OnClientConnected() Routine fires off, which is only raised under two circumstances: When a Client connects (obviously) When the server is told to shutdown
Now, the first one is handled just fine. But the second one is not. In fact, it has caused me a great deal of headache because it keeps throwing exceptions on this line in particular:
Dim _tcpClient As System.Net.Sockets.TcpClient = _tcpListener.EndAcceptTcpClient(IR)
When I hover over while debugging, I can see a few members that reveal exception data I could utilize; but unfortunately those members are private and I don't want to utilize reflection unless I have to since it could slow down performance where there may not be a real reason to.
I have thought of writing in a Boolean check to see if the server received a shutdown signal and that would indicate that it's time to not accept anything, but I want to avoid that if possible.
Is there any way to see if the TcpListener is no longer accepting connections and has had .Stop() called without reverting to catching the ObjectDisposedException that is raised? (because the Socket that is "accepted" is actually a disposed one)
I am working on a program that gathers test scores from the user in the form of a list box (array preferably). I need to be able to check the user's entries to validate they are between 0-100.
