I have a for each item in listbox:
try
'code goes here
catch ex as exception
end try
next
now, in my code, i also have if ex = certain error. i'd like it to go back to the top of the try. reason for not letting it do its thing is, i am wanting it to retry it, under the same item. So, is there a way to goto a portion of the code.
i was trying to make a free microsoft word plugin in vb.net. It automatically fills a web form. The main problem with the plugin is that it uses web browser control and once it has filled a form it will need to navigate another form. The form can only be filled once it has completely been loaded.so my approach is
1. navigate to first site when form loads
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
WebBrowser1.Navigate("http://google.com")
End Sub
2. use an integer i and use if statements to check which form to fill :
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEv entArgs) Handles WebBrowser1.DocumentCompleted
If (i = 1) Then[code].....
3. this is the main step. you see when main form loads, i=1 so browser goes to google.com (first form), when form is completely loaded, itchecks for value of i. Since i=1, it fills google. After filling and continuing i=2 and browser goes to my personal account page. This means browser again loads the document. Now i=2, so it fills my personal detalis. Now the timer starts. Since i=3, browser navigates to second site and fills the details.
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If (i = 3) Then
WebBrowser1.Navigate("http://blogger.com")[code]...
now the problem arises. The browser does not go to the third site. Once the timer has been stopped and started, the following code does not goto the elseif part (i.e. i=5) why is that so?
I've seen a few people on here saying that you shouldnt use GoTo in VB.NET and to be honest I've tended to agree as I have never needed to use it and there is always another way of doing something without using it. However, I'm just wondering what is so bad about it? I actually noticed that Microsoft seem to use it a fair bit in the internal .NET framework code, which is what makes me wonder why people are so against it.

View 2 RepliesI am trying to make a program which outputs an Invoice Number, which consists of the first 3 letters of a person's first name and the last 3 digits of their zip code. The user enter their first and last name, then enters their city, state, and zip such as:
Name: Billy Jones
City, State, Zip: Chicago, Illinois 42349
Therefore, the invoice would look like:
Invoice: Bil349
I can get the first 3 letters of the first name fine using the substring function, but I have been stumped on how to get past all of the text to get the last 3 digits of the zip code entered.
I'm currently making a code that will login to a cisco router, and show the version, then return the version to me. The connection to the cisco router is using telnet, and I'm using Dimac's w3Sockets code to Connect, login, and return data. Reference
But currently I'm having some problems, since the router sometimes need the login typed 2 times, or having a key pressed to update the terminal(telnet),meaning i have to check if it gets logged in or not. But the problem is that using dimac code, i can only wait() and waitFor(), and if it none data comes whilst waiting, it keeps on waiting. Is there away to do like: "if wait fails goto"
I've tryed "on error goto", but since its not a error, but just keeps waiting, that dont work. Also, To locate where it gets stuck I have it write to my textbox everytime it takes a step in the code, but its like the dimac code overtakes vb.net. ex: If i send some text to a textbox in the same sub as the connect code is, and it gets stuck at a wait, it dont even write to the textbox, eventhough the textbox.text command was suppose to execute before the wait().
Code:
Private Sub telnet(ByVal port)
TextBox3.Text = TextBox3.Text & Environment.NewLine & "Telnet func Called" 'Cant execute this if it gets stuck at login below. ??

I want to be able to read ONLY the link from the file.. In the first file above it would be after the "File1=" text in the file.. And in the other file it should be whats written after the "<ref href="" part..
And as you see in the second file there are three links, so to start with it should only read the first line, maybe later i could make a selection window popup or something..

View 3 RepliesI've got a DateTimePicker control on my form. The normal behavior is for it to allow the user to "move" between value fields with the arrow keys and remember the last date part that was highlighted when the control loses focus. Then, when the control gets focus again, that date part is highlighted. We all know this, I'm sure.What I want to know is how to access the control's selection properties/methods in order to have my DateTimePicker control always highlight the month portion when a user enters the control, regardless of what the last date part highlighted was.
