View 9 RepliesI need to grab some data from a webpage but for me the main problem is I can't grab the data the way I want. I want to grab the data in a listview control but my code is fetching all data within any span tag (span class "inputFieldLabel" which is not required) in a single column of a listview control. I am giving the format (source) of the webpage below and my coding in vb.net (2008),
<br>
<span class="inputFieldLabel">Following Are ...</span>
<span class="inputFieldLabel">01/02/2011</span>

I am building the 'TheBeerHouse' project in vb.net (the book is written in C#). Once I understand the concepts, I can usually convert it to vb. However, there are a few areas that give my some problems (which I will address individually). The first issue I have is the C# 'base' to VB 'MyBase'. [code] My understanding of this conversion is that I need to grab the attributes of the <articles> element under the <theBeerHouse> custom section in the web.config file.This code does not compile and the get the following error: 'MyBase' must be followed by '.' and an identifier.
View 4 RepliesI'm making a program for a class, as usual. I need it to grab the smallest number, of the 2 inputted numbers.Well, there is 4 inputted numbers. For instance the user inputs the following:
Price Ounces
20 4
12 4
I divide the numbers, and get 5 and 3.The better buy is going to be item 2, as it is $3 per ounce.But I need the program to grab the smallest number AFTER dividing, and then display that in a label. I need to know how to grab the smallest number. What statement do I use?Odds are, it's something simple and I'm overlooking it.

How to get id by class?

I got the solution as to how I could associate more to the elements within a combo box in VB. NET. (Not understood the code though, which is the reason for this topic)Suppose I wanted to associate each of these with a minimum few attributes while loading the combo, is that possible? .i.e I want An id as well as a count to get associated with each of these elements.1 Apple 192 Guava 123 Tomato 1094 Carrot 9..With only the names appearing in the drop down?? and not the other attributes..
View 3 RepliesI still can't understand classes in VB.net and I fell myself like a child.. I have found on MSDN example:Almoust everything is clearly, but DataGridView1 is created in this code in programm. If I have already DataGridView1 that created in designer - how can I override it events and ground it on other class?
View 4 RepliesI know that in a WebBrowser you can use Document.GetElementById to find an element by its name attribute, but I want to search the webpage for an element using the id or class atributes, how would it be possible to do this in a WebBrowser? I want to make it click on an image tag.
<td id="button1-cell"><img src="/static/button1.png" alt="Button 1" id="but1"></td>
Also, is it possible to InvokeMember("click") on divs?
there are any nifty in-built .net methods that can essentially return either the number of occurrences of each element in an array, or simply return the modal value.
View 7 RepliesI work in MS Visual Studio 2008, I have a VB.NET Solution which has three Projects, BusinessObjectLibrary (object properties), DataAccessLibrary (object functions such as selectAll, exportToExcel) and WindowUserInterface (UserForms c/w Controls)In my WindowUserInterface (project) I have a form called "rolFormGrid.vb", on this form, I have a DataGrid that gets filled with a function called "selectAll" when the form is loaded, I also have a button that calls the function "exportToExcel" and I have a Progress Bar called "rolProgressBar" ***.
In my DataAccessLibray (project) I have a class called "ROL_Adapter.vb", and in this class resides the function called "exportToExcel" which has all the code to create an Excel Workbook. When this function is being called, it can takes close to a minute to export to excel. We all know how users can be impatient if they do not see anything happening in the foreground when an application is working, that is the reason I want the progress bar.

Think of it as a way of highlighting certain areas of text in a TextBlock where the Run element is located, but applying an individual effect to that area instead.

I have a number of rewrite rules for a lot of things that I did in IIS7, like removing trailing slashes, canonnical URLs, lowercase lettering, and such. IIS altered my web.config, and everything works fine on the website, like it should. But in the Visual Studio web.config, the opening < rewrite > statement is underlined in blue, and at the bottom of VS, it says that the element 'system.webServer' has invalid child element 'rewrite'. But this is how IIS made it. I didn't do this manually. Should I be concerned with this VS error, or should I just leave as be, since it's working how it should work? Here's an example of my web.config:

I want to be able to reference an element in an array of structures by the name of the element in a visual basic 2010 function. For example
Public Structure myStruct
Public element1 as string
Public element2 as integer

Is it possible to reference a structures element by the element's name in a similar way to that shown above. The code shown above does not work, as the expression obj(i).[elementName] does not work as hoped.
I recently had the problem of trying to store an enormous amount of decimal places in a variable. Someone suggested that I create my own class to handle this. However I have researched extensively and can't seem to find a suggestion as to how I would do this. Would I read each digit into a list? How would I get each digit as to loop through a decimal, for example, and add each digit would still only give me 28 decimal places
