i am trying to create a small program that will calculate the miles between to postcodes.The way im doing this is to fill out a webform for each postcode and collect the returned Long/Lat values (i will then calculate the miles from that)
This all works well until my program freezes with no error message. It's after the same number of records as well and I don't know why.[code...]
I want to create a small delay so that my 1st set of codes run smoothly. How can I do that in vb.net ?
Edit 1 Suppose I have a few lines of code like this
..................Statement Line 1..............
..................Statement Line 2..............
..................Statement Line 3..............
[code]....
Only when the execution of first five statements are complete then only the next five can be executed
Is there a way of using some system online to calculate the distance in miles between to given postcodes? I need it to calculate in my vb.net web application a taxi fair estimation. So in some instances a more precise distance is require. Although not in all as it will specialise in long distances.

View 3 RepliesI have a NameValueCollection in vb.net and I need to be able to iterate through it and create an html form that posts automatically to a 3rd party site.
I have this to go off of as an example, but I am not sure exactly how to do this from code behind and end up with an html page that actually posts.[code]...
On form 1 , i have a number of buttons that open up different websites.What i want to do is when i click a button on form 1 , i want forum 2 to show ( Form2.show() ) , Form 2 will have a list (Buttons) of internet browsers.
View 4 RepliesI use Visual Basic.net to create a program that connects to several websites, logins, then post some data. I can't use the httpwebrequest, some java is required on those sites, so i use the webbrowser control.Now I created a form, some fields for input data and a submit button. The coding part is like this:
Code:
sub website1(vars)
'login here
'post some data
[code].....
The problem is that I can't control what happens after submit button is clicked. I need to pause or stop the process at any time. If I exit the program while processing, I can see that even if the window disappear, the program is still running!I tried to use a thread for this, but the subs only get called if I use begininvoke, or invoke on a starter thread.
I need to create a small program that runs in the taskbar to monitor browser urls for particular words.We are using it at work to catch people going to certain banned websites in the work place.Right now it works if i hand code each banned site into the code directly and run with a timer:[code]This works perfectly. Problem now is the Admins want direct access to add/remove different sites to the list.There is no way I am giving them access directly to my code (a bad day comes to mind).So I am attaching a small database with a small table to the server and allowing them to add URLS there. I am stuck in how to use this data though.I have tried pulling up the database column into a listbox but can not configure the code to check each line in listbox to compare to each browser window.
I also tried listed the items in a one column datagrid and try to loop through each row to compare each window.I need each browser window to be compared to a list of items and trigger events if a match is found.If your wondering why I am building this, our IS security people are all or nothing. Either no Net or Full Access.Also our people are a bit to smart to be tracked through history or simple blocking methods.

View 2 RepliesI ma trying to create a program to calculate my math grade. The way my math teacher explained the grading scale was each test is worth 1 point and each quiz is worth .2 points.
So as an example (add both sides up then divide by both sides)
100 =1
80 = 1
15 = .2
18 = .2
213 divide by 2.4 which equals your grade of 88.75
There are more quizs and tests in the semester and I want the numbers to change with the number of quizs and tests entered. The only problem is I am not sure how to code it. I though I would use IF AND statements but I am not sure where to start.

I need to create a "post office" program that will send html emails thru the system.net.mail framework.
For each job submitted to the postoffice the app would need to read a user created html email string from the database, read a string of email addresses to send to and send out the emails based on a set processing time.
The first step would be to parse out the email addresses to find out how many emails it needs to send out and determine how many it would need to send per minute to complete the job in 20 minutes tops. I.e. if 1000 email addresses are submitted per job it would determine that it needs to send 50 emails per minute to complete the job.
The part I am stuck on is how I should queue the emails. If the app determines it needs to send 50 a minute should I only load up the first 50 on a timer event then get the next 50 queued up for the next timer tick? Or would it be better to load up all 1000 in a loop and build in some kind of wait time after it sends the first 50?

I have an old VB6 application. I want to recreate it in VB.Net using WPF. But I am a bit confused about the "Model View Controller"-pattern. I have two books about design patterns (GoF and J.Bishop) afair this pattern is indeed not mentioned inside one of the two books. I have also searched the internet I found some java-examples. But I have still no clue how I should use MVC-Pattern (should I?) in my new WPF-application.Let's say for example my model (in fact it is more complex) is only a wheel rim (circle) with the properties Manufacturer, Diameter and Depth. The user should be able to modify the properties using textboxes and ComboBoxes.Could somebody create a small example that explaines the MVC-Pattern with WPF?Of course I like reusable classes to have a feasible concept throughout the whole application.

View 1 RepliesI am a beginner on Visual Basic but was able to create the 'skeleton' of the application I need to build. Basically, it is an application dedicated to keeping a check on the vinyl I have. When I buy a new record, I want to effectively 'Add New Record' on Visual Basic and be greeted with a page consisting of various forms such as 'Artist' and Title'. Once these are filled in, I want to click 'Enter' and for all that information to be converted to one of the pages within my application.
Here's an easier look at it...
There are LPs that have 10" and 12" sections.
There are singles that have 7" and 12" sections.
In the 'Add New Record' page I want to also have a drop down list with the above elements in, once 12" LP is selected and all the other forms are filled in and I click 'Enter' - I want the application to send it to the 12" LP section of the application.
I would like to create an application that can browse the DLL file and use the codes inside it. Not by adding it as a reference, or something. Just browsing the DLL file to use the codes inside it.
View 7 RepliesI have been trying, without success, to get rid of a �Blink� at the start of a small program.
My program opens with a title page (Form2, which is visible at 100% Opacity) that I want to fade after a few seconds, this works fine except that at the first reduction of opacity, Timer1's first 'Tick', the whole of Form2 blacks out for a moment. (Blinks)
I have a short demo program to show what I mean but don�t think I can attach it to this question. The code is shown here but I don�t know how to include Form1 and Form2. They are very simple however, they�re both Size 1000,600
Form1 has a single Button (Exit) and a Timer; Form2 has a full-size photo as background.

i have a small program to get text from a DAT file. the program gets all the text and puts it into a rich text box (rtb1) then I click a button (btnformat) to split the text in the dat file into indexes so that I can output the indexes that I want to an excel file. This program works when I use small amounts of data but if I use say 800 lines of text the program crashes/ can't handle the volume of data and just stalls.
