Web Scrapping (getting Output From The Web)
Feb 7, 2011
I am trying to extract some data from the webpage's element. Since it is based on the input I type in, the length of the output is different for every different input.
CODE:
I want what ever word/phrase of any length that is between "0.6em;">" and "</div>" earlier methods I've used for inputs was WebBrowser1.Document.GetElementById("Text").SetAttribute("value", TextBox1.Text)
I was wondering if there is something as simple for extracting the output.

I am working on a project that somehow uses the web request technique. But I'm facing a tough problem, my application is a web scrapping application. The website I'm scrapping has a combo box list and which of course fires a do post back on change. I want to use the web request to raise or fire the event of the do post back with the value I want and extract the web source page. is that possible?

What I am trying to do: There are three powershell scripts with different time delays as shown below.I am trying to run them asynchronously in .NET and I followed this article to implement Asyncrhonous programming. Where I am stuck:The I am not able to retrieve output after the events are invoked.The scripts are being called but then the program ends and it shows "Press any key to continue" in console windows.I don't what I am missing here.
Info: JobRequest is a class that I use to pass around information keep track of jobs.
Sub Main()

OurAsyncFunctionCalling("psDelayScript1.ps1", "-arg1 2 -arg2 3", 2)[code]......

I'm just going to throw all my code in here in case there's something wrong with a piece of the code not in the "SelectName()" sub.
Module Module1
Dim selectednames As String = ""
Dim index As Short = 0
Dim inarray As Boolean = False
[code]....
Here's an image of what it does (I suppose you can see what went wrong)13 inputs, 3 outputs expected, only 1 output given.As from what I've figured out so far, it's doing the correct amount of loops etc. It's just as soon as it starts generating the "winner" for the 2nd game key it doesn't get a string value from namesarray.Also, why is
For x = 0 To totalnames - 1
Debug.Print("namesarray(" & x & ") = " & namesarray(x))
Next
not giving me a debug output?

1. (Add) Create a program that will output the sum of all the odd numbers between 1 and 99 inclusive.
2. (Cash) Allow the user to key in any number of item prices for items purchased in a discount store. Display the grand total amount of all items including an addition of 8% tax on all items.
3. (Pumpkin) Allow the user to input any number of pumpkin weights in pounds into the program. Output the average of all pumpkin weights, the largest pumpkin weight, and the total number of pumpkins.
Right now I am not even sure where to start. I attempted #1 and I started by making a variable of sum = 0 and using a For Loop with a variable of Sum and Initial value of 1 and final value of 99 with a Step of 2.

From my application I need to run a command and parse the output. I can do this with no problem but I don't want the command to be displayed. I hoped WindowStyle = ProcessWindowStyle.Hidden would work but it doesn't. Take the sample code below for example. It works fine but the command window still visibly opens and closes very quickly and I need it to never show its ugly face. How can I fix this?

I've got a micro controller with 4 channel ADC that I want to make a program for. It will be for data logging. I want to take each channel and display it in 4 textboxes to begin with.Later I like to do some conversions of the data to show temperature , use a lookup table and a few other things in each of these boxes, but at first I'd just like to concentrate on getting the data split into each box.The chip output is 8 bytes . The first two are the channel select and the next two is the data. Output of the chip is in ASCII. I don't want to send to the chip, just receive.If I view the output in decimal I get 1xx 2xx 3xx 4xx (xx being the data to display).

Is there a way to add to the "Show Output From" dropdown list. I've been going in circles on MSDN looking at Listeners, Writers, Trace, Debug, ConsoleTraceListeners etc. with no luck. I really would like my own pane for debug output because I don't want to disable any of the messages in the debug pane, and a lot of stuff gets pumped out there.
I found a way to add a new pane to the output tab through a macro/addin but don't know how, or if, it can be written to through code.
Short of that I'm really just looking for a better/more intuitive way do display debug output. Colored would be nice. I've tried very unsuccessfully to use nLog - but the configuration/documentation left me scratching my head.
Is the output window really what most people settle for?

How is it posible to align each "Column", so that, no matter the size of each value, the columns line up perfectly under each other. I'm using a listbox for the output, I thought I had an understanding of this but apparently I don't. I am using a fixed width font and the screenshot shows my results. I have done this before but not in awhile.how to set up the zones. I know the minus sign in front will left justify the column results but I'm having trouble with the other columns.
