I'm currently grabbing HTML from my site using webrequest and storing it in a string. I'm looking to take this string, and scrape all of the prices in order to calculate this against my cost price (for a consistent profit spreadsheet). What is the most feasible way to do this? Would using a webbrowser control be a better idea?

View 9 RepliesI have an app that contains a DataTable that I must summarize. In that table is a Status column (also the index order) and I want to write a loop in which I compute the count for each status. So I wrote my loop and tried to use the compute function of the Datatable class, but I cannot get it working due to some constraints - specifically this...
[Code]....
You can see what I am doing here is grabbing the string value of the Status column, and then trying to get a count of how many records have that Status. My ultimate goal was to cycle the Table and count each time the status changes. But the error I get has to do with where I store the Status in a String, and then issue the second parameter on the Compute function which contains a variable (sumString) and this is where Compute is crashing - and of course, I can see why - my Status is not literal and thus not in quotes.
Generally speaking, is there any way to manage this kind of thing? In my (very) old FoxPro days one would use a macro such as "Status = &sumString" and VFP would translate sumString to its literal. I have never discovered a way to do that in .NET.

I am trying to use my web browser control to get retrieve date from a specific page, including all sub-page content. Problem is some of the sub-pages are on a separate domain and thus I am getting a permission deigned error when i try to access the frame [through document.windows.frames(i).document].Is there any work around to do this, even if I have to manually change security settings? I tried turning all my settings in IE to allow and still same error. I will only be running the app locally and no one will be browsing on IE so I can literally change anything needed to get this to work (even install older version of IE which may allow it but can still handle JS processing).
Note the reason I am using web browser is a great majority of data I will be accessing is JS generated, so I need to access the DOM after JS processed / generated the HTML. Because of this, simply using SOCKETS to get the HTML is really not an option. Even if I had the HTML, I still need some type of engine to process all of the DOM elements based off javascript.

I have a listbox where the user can add items to it with the following schema "count, id".I want to take each item from the listbox,use the split function so I can "take" only the "count," part and then add the "count," part of each item into a string.I mean I want something like this:
user adds 3 items in the listbox:
1, 100
2, 200 and
3, 300.
I want to make it,so a string can be formed, and contain the "count," part of each item which in this case is;
in the first item the "count," part is "1,",in the second item the "count," part is "2," and in the third it's "3,".I want those "count," parts to be stored into a string (which will result into having this string "1,2,3,").
