I am fairly new to vb.net, but have quite some experience with Delphi, and did some VBA. Oh, I'm old school. I like DOS.
So, I need to write a program, and chose vb.net (visual studio 2008) as my language to do this in.
What the program is supposed to do is generate a webpage hit (but not necessarily render the html in a browser) and then parge through the returned HTML code, finding links, certain key words etc.
I have tried a few things like converting HTML to XML and then using an XML navigator to get input elements but I get lost whenever I start this process.What I am trying to do is to navigate to a website which will be loaded using textbox1.text.Then download the html and parse out the input elements like . username, password, etc and place the element by type (id or name) into the richtextbox with the attribute beside the name.[code]Any clues or how to properly execute an HTML to XML conveter, reader, parser?
View 2 RepliesI'm working on an app in which the user copy and pastes from a website into a richtextbox then the program uses the phone number, name and "match by string" from the richtexbox. What is copied is like an Excel table type thing but all the data is in Column "A". The data isn't tab deliminated. If i split on spaces then that will give incorrect results since some of the pieces of data have spaces in them. It looks like I'm about to do some really nasty ugly coding to get to the values I need. take a look at this snippet of data and tell me of a graceful way of getting the name, phone number and that last value in the line if such coding exists? This is the info I would need to pickup on in the first row of data. SHEKITA LLOYD, (xxx) 956-80, and Non-Payment of premium.
This is a sample of the data:
Producer Code Policy # Insured Name Insured Phone Policy Status
08xx57 350xxx1xxx Cancelled Non-Reinstateable 01/09/2012 Non-Payment of premium;
08xx57 350xxx1xxx SHEKITA LLOYD (xxx) 956-80 Cancelled Non-Reinstateable 11/18/2011 Non-Payment of premium;
[CODE]...
The info i need extracted is formatted:
<TD><A HREF="http://xxxxx.com/xxxxxx/index.html"><IMG SRC="../xxxxx/thumbnails/xxxxx.jpg"> </A></TD>
<TD>=== <B><A HREF="http://xxxxxxxxx.com/xxxxxxxx/index.html">LINE 0</A></B> ===<BR>
<FONT SIZE="2" COLOR="#400080">
[code]....
how do i extract the info between TD=== and /a and Line 1,2, and 3 and store it into a database from a live website?
Ok so here is the HTML of the page:

I just want to parse simple expressions like IIF(FVAL(PFC) = TRUE, (IIF((ORGVAL(BAS, "2012/12/31") + ORGVAL(DA)) < 6500, (FVAL(BAS) + FVAL(DA)) * 12%, 780)), 0)`After parsing this I should be able to know what functions contains what parameters.
[Code]...
I'm stuck with .Net Framework 2.0, so no Linq or lambda expression goodies for me. Also I want to include the code in my custom library and not just reference it. Can anyone point me to some good library or code.
I just need to parse and not evaluate the expression and find what tokens are in use. After finding the tokens I need to change the expression string before parsing, like if the function ORGVAL is used then the parameter passed has has to be prefixed by an underscore. Like ORGVAL(BAS) will transform to ORGVAL(_BAS). Some functions can have tow parameters like ORGVAL(BAS, "2012/12/31") and this will transform to ORGVAL(_BAS, "2012/12/31")
NOTE: IF THERE ARE OTHER WAYS OF DOING IT PLEASE LET ME KNOW. I WOULD LOVE TO AVOID A PARSER AND LEXER.
What Im making is like a face book and tagged login from my app
1. I have Combobox with 3 urls in there ( Facebook.com Tagged.com and Bebo.com )
2. I have a Form2 with webbrowser
3. I have a Button when clicked it should open up my form 2 and preview of the website which I selected in my combobox in form1
All I'm trying to do is when I select lets say facebook in my form 1 and click load it should open up my form 2 with facebook website in it.[code]Now when I click my button in form 1 it will load Form2 ( named Explorer1) but my form2 is not showing me facebook or tagged page for some reason

View 2 RepliesI have a ASP.NET 2.0 website created in C# that acts as a completely independent site and I am looking to integrate this into an existing ASP.NET 2.0 website created in VB.NET. Unfortunately I just don't know much about the server management side of ASP.NET yet so too much I'm unaware of when it comes to IIS configuration etc. Does anyone have any advice as to how I can go about integrating this? Basically I want to host it in a subdirectory from root so when you hit example.com/myindependantsite/ it will pull up my C# site.
One possible solution I came across mentioned just dropping the project folder into the root directory and setting up that directory as an application virtual directory in IIS? A few other random questions were small things like would my application relative links (~/for-example.aspx) stay relative to my root subdirectory if it's made into an application virtual directory? Just trying to get this running on their site but like I said it's completely independent so want to preserve my websites environment.
I want to create a program to fetch information from a website (that's fine). However, you need to be logged in to get this information. I just want two simple textbox controls that I would type my username and password into and hit submit and the information would be returned to me so I can use it. (I don't want to use a webbrowser control)

I have an app that the user selects information and it writes to an XML file. The user can increase and decrease the information in the XML file so it is dynamic. The other app reads the xml file and uses it to complete tasks. Since the XML is dynamic my code needs to account for that. Right now I have only allowed the XML to have up to four values in a certain node, I would like to allow more but I will need to increase the Select Case function.[code]

View 3 RepliesI may be getting in way over my head, but here it goes. I am developing a small application for use on a helpdesk. The application will be installed on the client pc's and will be used primarily by the end user to assist the technician on the phone if the user's pc is offline or inaccessible. One part of the application gives the user their IP address, DNS address, DHCP address, and gateway address. I have it to where it will put all of those in the corresponding fields inside a form, but it does not work correctly outside of a domain. Outside of a domain it only gives the IP address. I am sure it is probably how I coded it, but I cannot think of any other way to get that info in a user friendly way. Is there a way to parse a command prompt command to specific fields inside of a form such as the command ipconfig /all?

Well ... obviously the split does not work with embedded commas in a field. Looked at TextFieldParser, but it is in the FileIO class and the module is passed a IO.StreamReader. Can it work?
Or how abour a RegEx? Does anyone have any suggestions? I have look around on the internet and it seems like a common questions with a bunch of wild goose chases.

Here is a snippet of an XML file that I need to read with VB.NET[code]...
I am familiar with creating a new XmlDocument and using the Load method to read the file. I know how to get a collection of child nodes and loop through them to get elements and attributes. But in this case, I need to extract all of the data between the two "verse" tags (the starting one with the "sID" attribute and the ending one with the "eID" attribute), including the tags and the data in between as one continuous string. I can loop on the nodes, but I only get the "w" nodes and one final "#text" node for the period, but I don't know how to get the spaces and punctuation between the "w" tags.
I have a comma delimited text file with the U.S. States and their respective state bird listed in the following format.
