I am still learning the ropes of vb.net. Most of the time I get by fine, using google and searching here. But i've run into a road block. I am trying to extract email adresses from the source code of my website, suppose I can populate the Rich text box with all the source code, and the are emails sitting inside. How would I extract the emails from it and put them in a separate box.[code]...

I have an application that receives data input from an automated set of devices. This data stream I have managed to capture & get it into a list box which I can sort based on the Device ID & the time that the response was received.There is a set time window for the devices to transmit their data into the application and during this each device is not limited to the number of responses it can send (ie :- Device 1 can send in 2 responses where Device 3 can send in 40 responses, etc).All of the responses are captured, listed & sorted within the listbox (this bit is working ).I now need to extract the last (ie:- latest) entry in the listbox for each Device ID & this is where I am stuck. I can retrieve the last item in the list but cant seem to extract the last item for each Device ID.[code]

I have the following code to open a webpage:
Dim IE As Object
Dim x As Integer
Dim c As Variant
[code]....
The page that opens is in xml and in that xml there is the "page_count" that I need to pick out so I can tell my macro when to stop looping. I have dimmed it as "c" in the code above. Following is the XML.
<search>
<total_items>360</total_items>
<page_size>100</page_size>
<page_count>4</page_count>
Somehow I need c = "4", which is the "page_count". Does anyone know how I can pick out the "4" from the xml on my page?

I need to convert a VB6 application into VB.Net Windows application. The program pulls data from MS Exchange (UserID, firstname, lastname, etc - not the emails themselves) and places it in a .txt file. The code has been converted, but the program does not work. When the application is run, the .txt file is created, but is blank and I get a pop-up that shows the following, "trying to access email in outlook do you want to allow this?". The popup box is gone in an instant and when I try to click on yes, it does nothing. I always have to end the program as it is non-responsive.

Note the required data from the PDF document is in same each time, just different values.

View 1 RepliesTo simplify what I am trying to do, let's say I have a text file with only one line of data.
The data in this case is color info for one pixel:
Color [A=255, R=255, G=200, B=128]
What I am trying to do is read the text file and extract the hex color info and save them to their own variable.
So once the code has run, these should be the contents of the three variables.
RedData = 255
GreenData = 200
BlueData = 128
I have managed to get something to work but I know the code is terrible and is incredibly slow when I try to run through hundreds of lines in a text file.

I know it's possible to retrieve URL source codes, slice and dice them either through VB.NET or RegEx but that only applies to text/code that are in plain text like HTML code. But how do you extract code from JavaScript that in the downloaded source code doesn't display the data inside the variables, but instead the actual variables?
Below I have an example code of JavaScript variables inside a downloaded .HTML source code that, when the webpage is loaded, displays the information/data contained inside these variables in the web browser. But the data itself isn't "downloaded" or stored in the source code.
So my question is: How do you extract/retrieve the data from within those JavaScript variables?
<td>
<div class="showUserText">
<div class="outerRatingBody" style="display:none;" >

Is it possible through VB.NET to get what ever is inside those variables?

I've used Python on and off for the last decade in a very limited capacity (mostly to do my math homework), but this project I'm working on now is almost overwhelmingly complex and difficult to me. Mostly due to my lack of immersion in programming as a whole.
Anyhoot: here is what I'm trying to accomplish: part of our new VoIP system is an enterprise messaging component that will take a voicemail, embed it into an email (as a WAV stream), and then drop it into the email address associated with that extension. However, if that user is not configured to use enterprise messaging or if they've not opened their email client in awhile, the voicemail+email object just hangs out in a folder on the enterprise messaging server. When an employee is terminated, the EM server continues to take VMs and store them in this folder.
As a part of the directive from management, we've been instructed to deliver these voicemails to the employee's manager for review before we pass the extension and mailbox onto someone else. What we've been doing up until this point is opening the VM+Email objects in Notepad++ one at a time, removing the email data from around the WAV file, resaving it with a *.wav extension, and them attaching them before sending them along.
Suffice to say, this process becomes very tedious and error prone when you have a TON of these to work with. I thought that I could use VB2008 to automate it.
The code I wrote grabs the VM+Email object as a text stream, uses an InStr() and InStrRev() function to identify the beginning and ending points of the WAV stream, and then uses a Mid() function to extract it before resaving it as a WAV file. This works, but the problem is that the WAV file it saves is barely audible and it sounds awful.[code]...
