Asp.net - Parse Data/numbers From Table Cells C#?
Dec 10, 2011
I have a string which contains html code from a webpage. There's a table in the code I'm interested in. I want to parse the numbers present in the table cells and put them in textboxes, each number in its own textbox. Here's the table:
<table class="tblSkills">
<tr>
<th class="th_first">Strength</th><td class="align_center">15</td>
<th>Passing</th><td class="align_center">17</td>
[code]....
As you can see there are 14 numbers. To make things worse numbers like 19 and 20 are replaced by images and numbers lower than 6 have a span class.

Given a string as a form of input (parsed from an input file) which represents a number and a mathematical operator (<, >, <=, >=, !, !=, and a few others), what is a really fastefficient way to chop off that operator, compare it to a list of valid operators, and then set an "operator" variable to a state (i.e., Enum) representing the identified operator, then return just the number (as a string)?I'm open to various ideas and implementations.I've tried several (about 6-7) myself, and find I'm not really satisfied with the speedThe fastest so far is a For Each loop that walks my list of "valid operators", and compares that operator's string representation against the chopped off bit from the numeric string. I determine the amount to chop off by the length of each valid operator in the valid list.
Here's a code example of the fastest implementation. Assume input like <378 and a valid ops list of <, >, !, or >=79 and a valid ops list of <=, >=:

I have a string I want to parse. I could write the code to do so, but I figured that VS.NET has a parser that should do this for me.however, I can't find it. All the searches I do return info on how to parse numeric values in string form into real numbers. It would be nice if the MSDN search had some ways to allow users to enter more details than just search text and 3 ways to filter out irrelevant stuff. In any case, I also tried things like string.parse (nope - although I kinda figured this would be it.) I also looked at Enum.parse, but the code indicates that it works with arrasy of items, not strings.

Here is what we've been trying to do.
We have a button that loads up a form. It opens up a form and there is a Table. Its the history table. Well, the way this table is loaded is we run a function known as HistoryTableSelectSubset. Now, this has worked very fine! Not a problem.
This is our problem. We want three columns in this table. First, QueryDate (WORKS!). Second, SQL (WORKS!). Third, MYNEWCOLUMN (Fail). What we want in this third column is basically the SQL column but with it all word wrapped.
So, instead of seeing only the first line of the SQL on the table if it is written like this:

I am having trouble with automatically filling a table in word from a asp.net app - i use bookmarks in the next top row to determine what data should be inserted into the columns of my tables. However, i am having trouble in getting the individual cells bookmarks and get all the bookmarks from the row instead. This is fine if i have one bookmark in each column as i can use the 3rd bookark and assume that is from the 3rd column, but if i were to have 2 bookmarks in one column, how would i know which column it was that contained the 2 bookmarks?Here is my code that returns all bookmarks for the row even though i am selecting a single cell; and therefore using bookmarks(1) - always the same bookmark(the one in the leftmost

The problem I am having is that It pulls out the 28,900 fine but I need to pull the rest of the information IE the 23,132 and the 170,000 and they will get placed into other Labels. Now they are not Static numbers they change all the time to higher or lower lumbers.

I've searched for this everywhere, but can't find a solution after trying for two days. What I want to accomplish is creating a table in Word (n-rows, and 3 cols,) (which I successfully have) and for each row that has a new date, I want to merge all three column cells just for that one row with the date. For every other row, above and below, I still want to preserve the 3 columns structure. What happens with the Merge() method is that all the rows merge, not just the row I'm currently on. I did a macro and noticed that there is a Selection.MoveRight() option I can do, but I can't yet figure out how to put all these statements together to accomplish this. When I do the MoveRight, trying many variants like the following:
oDoc.ActiveWindow.Selection.Tables(1).Range.Cells(wordRowIdx).Select()
oDoc.ActiveWindow.Selection.MoveRight(12)
I get a member cannot be found for the first statement.

My main goal is to have an excel spreadsheet that automatically plots the overall success of my stock portfolio over time (% change over time). I've been able to incorporate stock data into my spreadsheet by linking it to the web, but the trouble is the spreadsheet will keep no history of what the previous stock values were, so I can't graph how things change over time. This sounds like it might be too complicated to be built in to excel, so I was wondering if anyone knew how to program this in Visual Basic. Maybe something like this.... If refresh then new cell plus new time stamp. Another possibility would be to have a whole bunch of cells that refresh only once but at longer and longer intervals, e.g.,

I am trying to parse a file generated by LGA Tracon that lists the position data for aircraft over a given time frame. The data of interest starts with TRACKING DATA and ends with SST and there are thousands of entries per file. The system generating the file, Common ARTS, is very rigid in its formatting and we can expect the column spacing to be consistent. Here is an image to preserve the exact formatting Here is a reduced text file.

We are using the following code to try to parse some text data from the URL below:
Dim strURL As String = "[URL]"
' *** Establish the request
Dim loHttp As HttpWebRequest = DirectCast(WebRequest.Create(strURL), HttpWebRequest)
' *** Set properties
loHttp.Timeout = 10000
' 10 secs
loHttp.UserAgent = "Code Sample Web Client"

The problem is that the response we are getting in code is incomplete when compared with what actually renders in the browser. The html we are getting shows a javascript function in the body of html where what we really want is the result of the function, which includes the data we need to capture. This is confirmed by loading the page in Google Chrome, clicking on the text "100360" and choosing "inspect element" which allows us to see the full page response with the data we need, specifically the following line:
<pre class="pre-longText-wrap">100360</pre>
How to get this "raw" page response? It may be that the script is taking a few seconds to respond and that we are only seeing the initial page response.

have to write a program/application (which I already started in VB.NET 2010) that connects through Panasonic KX-TEM824 PBX machine via RS232 port (cable already connected : COM15/16 depending on USB I connect) and while it's connected to parse(receive) the data from the PBX itself, data that has caller ID, time of call started and ended, duration of the call and etc. I have found some already application on the Internet that does the work but they are free to try after awhile requires to buy or restart the app again. But I assume there's not much to implement on the code side.
