VS 2008 : Email Program Not Responding?
Jun 3, 2011
I am making a mass emailing system that reads off of a xml document and sends an email based on the stored object made from the XML tags.This program will have to send hundreds if not thousands of emails out. I made a test XML document with 160 emails to be sent out to my address.The program gets a (not responding) after about 10-15 emails, (although it keeps sending). Also the email sent counter lable doesn't change at all during the sending, the progress bar works however.Also, when I tried running it it stopped at 140 emails.
' Algorithm
' Show the progress bar
ProgressBar.Visible = True

I've been working on a program that generates a batch file, then when you press a button, it executes that batch file. There are multiple batch files attached to each item in the list box.
[code]...
The only thing that it does when I press the button, is starts the batch file, then goes to function searchtitle, which executes the batch file again when it finds out it didn't work properly.The button text doesn't change, none of the items are being added to my first list box, and I can't do anything to the window after pressing the button. It constantly opens the batch file every 5 seconds or so.

I have written a very simple program to simulate the operation of some electrical relays which respond to buttons pressed on a form.The important thing in the program is the pick and drop times of the relays so I use about 40 timers to simulate the operation
of the relays each stimulated either by another timer or the operation of a mousedown operation over an area of the window which has a GIF background.
The program works great when simulated within VB2010 Xpress but when I publish and install on either of my 2 laptops it freezes and does not respond to the mousedown procedures. It seems slightly better if I don't enable XP visual syles but still does not respond enough to be used. I am running 12 procs each time a continous timer runs out but altering the value of the timer does not make any difference. I've also noticed if I minimise the window and reopen the window it does move on slightly but still never responds to the mouse.
Also the timers in the program for the relay times seem to work at strange values and not those set sometimes? It seems to work OK on my main PC if I install it

I have a form with 3 background workers. On the click of a button all three start async. Once they all finish my program stops responding. If I run one at a time I encounter the same error.
'Background worker 1

Try
Dim source As String = _Topsource("[URL]" & gamertag.Text)
Dim statstbl As String = source.Remove(0, source.IndexOf("<div class=""statWrap"">"))

I have created a little program that helps me keep track of tons of data by inserting it into sql. I created 5 forms and all 5 can insert data at the same time, but mostly just 1 of these is working continuously. I have noticed that the program will run, then at random times it will stop responding (can't minimize/click on anything/data entry stops), and the only way to stop is to kill the task. I can't even click in the debugger to set a break point when it happens, and setting breakpoints before debugging is useless as the program could run 2 hours and stop, or 10 minutes and stop. 5 forms, they open different excel files, insert data into sql, and repeat.

I'm trying to get my program to send very simple text email messages. I did do a search beforehand, and found that I was having the same issue as someone else, but the specific question I have was not answered --
I've learned that if you're trying to send mail, you need an SMTP server... I found this list here but every one of them I've tried yields the same "Failure sending mail" error.
Here's my
Dim mail As New MailMessage()
mail.From = New MailAddress("me@mycompany.com")
mail.To.Add("destination-email@whatever.com")
[CODE]...
Is the problem that I need to show "credentials" (i.e. user/pass)? If so, what would those credentials be? Can I use my yahoo email SMTP server with my login info to do it? And is this all I'd need to add to add the credentials?
smtp.Credentials = New NetworkCredential("MyUsername", "MyPassword")
(before the smtp.Send, of course)

I have to make a basic program that: Create a program with a simple interface that
1. Asks the user type his/her email address into a textbox.
2. When the user clicks the "Evaluate Email Address" button, one of two message boxes pops up: "That is a valid email address!" with an "Information" icon, or "That is an invalid email address!" and on a second line, "Please retype your email address.", with an "Exclamation" icon
3. To be considered valid, the email address must -include an "@" symbol, and -it must end in either ".com", ".net", or ".org" or ".edu" (I don't know how to check a string and test if its last four characters end with any of these and make it say not valid email address. I think I might have to use a case statement)

I have a user app written in VB which up till now has relied on winsock to connect to another device we have. The user app logs onto the device and then send / receives status reports from it which are used to set the controls on the apps forms.
This has all worked well for a long time but I'm now looking to move away from Winsock as I know it's not 'the right way' to do things and I also need to be able to send non ascii characters between the app and the device it's connected to (implementing multi language support).
The issue is with Winsock it would simply throw the DataArrival event when a message was received and I could then process the message and act upon it. When using a TcpClient socket connection I'm running into problems as all responses are on the socket thread which means I can't simply change controls on the main form without using the Invoke check.
What I want to be able to do is have the thread running the TcpClient simply alert the main form thread when it receives data and make that data available to the main thread so it can start processing it and triggering all the other functions etc required (these also interact with the Form). Whilst this is happening the TcpClient monitors any further messages and sends response messages as requested from the main thread.

I'm uploading an image to url... etc. The trouble is my application stops responding for 5-10 seconds while the image is uploading. I want to use multi-threading to stop it doing that but I'm confused with the whole way to use controls with backgroundworker. [code] I guess its the textbox which is causing the problem.

I'm trying to send my program (a very small program) to a friend by email, but the two methods I've tried are both causing errors at his end. I've tried the two methods described in the helps files - firstly, just finding the exe in it's folder, compressing and sending it by email. That worked for the first few files but now it no longer works. Secondly I've tried publishing the file using the build option to a DVD/CD (i.e file). The file works fine to install the program on my own machine, but when I send it to my friend (compressed again) he gets errors.
