Been working on a function in my program that uses an embedded web browser to take the user to a certain website. In this case, I want it to search www.rhapsody.com for music tracks. The problem is, the parsing is all screwed up. The form can't send a multi-worded parameter.The function is like this:
ElseIf video = True Then
Dim temp2 = InputBox("Enter the artist and song title of the video you are watching, and Crystal Rain will try to find an audio version.")
WebBrowser1.Navigate("http:rhapsody.com/-search?query=" + temp2 + "&searchtype=RhapTrack")
End If
It puts the user input as a search query in the URL. This works fine for songs that are only one word. But when I try something like "I love you," it takes me to rhapsody saying:
Track Search Results: i%20love%20you
It's an annoying %20 parser thing in between each word. Is there a way to address this parsing problem? Somehow get the form to send the search to the web browser without the %20?
I would like to be able to parse vb.net code files, so I can examine the collection of Subs, Functions (and their contents, including comments), private variables, etc. I can be open the actual source code files. So for example, if I have:
I'm creating a vb.net winforms application that will take in user given strings, parse them, and print out labels with variable information. The given string will be used in all the labels, but the variable part of the string will change with each label.
My question is: is it better to parse the strings one time, then store those values in arrays, or to parse the string each time a label is printed? Which will perform better? Which is better practice? What is the proper way to test something like this?
besides still being a newbie to programming. I need to import the information from a xml document into a sql server 2005 database. I have spent the last week searching the web trying to figure out how to do this. From what I can tell I should either use a T-Sql statement or SQL Bulk Copy i'm using vb.net 2008 Pro as the application front end. Here is the Schema and a small part of the xml document.
I have been parsing xml content using the xmlreader and cannot use the xml document but so far it works getting all elementcontent except for the attribute contents. I need to parse the link below found in the following entry;[code]
I am parsing some xml entries using the xmltextreader and looking for the elements I need by using different textreaders for each in a different loop as follows:
Dim treader As XmlTextReader = New XmlTextReader(New StringReader(item.ToString)) While treader.Read If treader.Name = "summary" Then content = treader.ReadElementContentAsString
[code].....
and I do the same for each element I am looking for. Now the problem arises when I get the results for each. I use an arraylist for each element and at times I will have an unequal amount like 100 for summary, 100 for title , 99 for id etc...is there a more efficient way of doing this by checking the entry if all the nodes are there and then just skipping it if it's not.
I'm having some trouble putting the pieces together.First of all, I'm currently using the WebBrowser component, but would be plenty happy with HtmlAgilityPack if it had some decent documentation, but for a newbie as VB.Net, it's a rough road.
What I'd like to do is grab all the h3's with the "this-class" class and stash them into an array (one in each array element).I'd then like to search through each one and see which has "And Another Title" - which I already have the code to do... I just don't know how to do the first bit.
we are trying to use google to get exchange rate prices. they use a csv file which we get the code to go out and get.what im trying to do is pick the first line of the file and just use that. i have the following code but its not just picking the one line.
I am trying to create a program in VB.net to help me fix broken computer systems by parsing log files. I have some ideas but I have only built simple programs previously. I have ideas how to do this but so far my attempts haven't gone so well.Specifically I can either import a txt type file or copy and paste the contents of a txt file into the program and then have it compare what has been posted to a good/bad list then it reprints out what is bad in color coding. Also if their is a way to update the file it uses for comparison by entering in a txt file that would be stellar.
I want to parse text from PDF file. Is this possible only with .NET framework? I was read about some libraries like iTextSharp or PDFBox. What do you recommend?
I am trying to find the value of <media:thumbnail url>. Right now I have an xpathnnavigator set up but if i need to use another method of parsing the xml, I can do that.
what is parse / parsing I often see it used yet i can't reary find any reference on how or what parsing may do or not do. Anyone can explain what the parse method does and is intended for?
In a perfect world my xml feed source would produce perfect xml ..that is not the caseam parsing an XML feed that sometimes has ampersands and dashes in the content that messes up my parsing.I've tried doing pre processing with find/replace to get rid of these characters but then I get another type of error
So when I was getting a null value using selectSingleNode, I found that I needed to declare a namespace because I was using the xmlns attribute. My question is why I need to use a prefix when parsing the xml, if I don't use the prefix in the xml file itself? The reason I have the xmlns attribute, is because the receiving end of my xml output requires it. I would rather read it in from the base xml than have it hardcoded in the program.
Dim myRequest As System.Net.WebRequest = System.Net.WebRequest.Create(url) Dim myResponse As System.Net.WebResponse = myRequest.GetResponse() Dim rssStream As System.IO.Stream = myResponse.GetResponseStream() Dim rssDoc As New System.Xml.XmlDocument() Try rssDoc.Load(rssStream)
[Code]...
Folks this is what I'm using to parse an RSS feed for the last updated time. Is there a quicker way? Speed seems to be a bit slow on it as it pulls down the entire feed before parsing.
Imports System.Web Imports System.Net Imports System.Net.ServicePointManager Public Class GetSource Function GetHtml(ByVal strPage As String) As String tryAgain:
[Code]...
What I got here is a vb.net code where I parse the website for its html This function works fine. The question is this...
1.If I run 100 threads with this function at the same time, Will it work?
2.Won't it affect my internet connection as well?
I don't want to waste time creating threads and codes a hundred times so if you know the answer please advice me on what should I do instead
So the following code will return the version number which currently is 6.59 which is what I'm after. [Code] But then i remembered that releases are done as following: 6.59, 6.59b, 6.59c, 6.60, 6.60b etc. So when the b version of 6.59 is released the parser will still return 6.59. So how can i make this code better?
I have a web app with a form that I am trying to pass to an ASP.NET server (using VB.NET) and then on to a MS SQL Server table. The form uses a jQuery datepicker in several textboxes and formats them as MM/dd/yyyy. The form fields are then passed through a PageMethod to the web server which takes the various field values and combines them into a SQL UPDATE command.
I am constantly getting the following error whenever I try to execute the SQL command:Conversion failed when converting date and/or time from character string.Here is the code on the server:
Using myConn As New System.Data.SqlClient.SqlConnection(CString.ConnectionString) myConn.Open() Dim cmd As New System.Data.SqlClient.SqlCommand("UPDATE table " & _
[code]....
Note: I've tried about twenty different ways of parsing the dates, converting them to dates, changing around the formats and none of it has worked.
Note 2: The conditional statements at the end are simply to prevent empty date fields from being stored in the SQL DB as "1/1/1900", but rather as an actual SQL NULL value. From debugging though, it seems that this is not the issue - it is when there is an actual value that the error is fired.
i am having problems trying to code this application, here is the assignment: Amusing Toys, Inc. wants to store the description and the number of items on hand of its toys in a sequential access file named stock.txt. The company's sales manager wants an application that lets the user enter the descriptions and the inventory in tow list boxes. Then he also wants to retrieve the file so it is possible display the inventory of a toy whose description he selects from a list box. The List box with the description should appear as soon as the application is loaded. Create an application which: initially adds the information to list boxes so the information can be checked, places the data in one or two arrays, saves the information for retrieval later, contains test data for at least 10 items.here is what i have so far i cant get the information to line up correctly in the list box from the text file and also i have no idea on how to get the quantity to show up after i get it to line up correctly i think i need an array.
Public Class MainForm Private Sub addItemButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles addItemButton.Click Dim heading As String = "Department" & Strings.Space(2) & "OnHand" Dim description As String = String.Empty
