My app currently sends GET httpwberequests and parses the content after reading the response stream for each request and the repeats this process over and over. I need to implement a continuous http stream which uses the same GET request but the connection stays open, from what I understand. how would I change my existing code to do this?

i want to type in a name to a textbox like type in "Ben" to textbox1. Then i want to click a button and have correlating numbers, say 126 show up in the textbox2. Im using a function to do this, how would i write a function that takes the string in textbox1, goes through each letter and sends back a numerical value for the letter through the function. I know how to do this with text files with stream reader, but don't know how to do this with strings.

View 3 Repliesi have a webrowser and i need to find about 10 links all begining with [URL], from the html code of that site. The websites in the code wont be clickable, they are usually listed on a forum. The end of the link above can be diferent, so im not sure how you could find the end point. No assumptions can be made as to the code that will be after the link, as every website is different. The link then needs to listed in a listbox for further processing.
View 6 RepliesI already know the basic procedure of how to read specific cells of an .xls file using VB.NET but I can't figure out how to automatically get all the data from such a file.Basically, I'm obtaining the data like this:
Dim xlApp As Excel.Application
Dim wb As Workbook
Dim ws As Worksheet
xlApp = New Excel.Application
[code]....
In this case, I know that there will be content in the first 10 rows of the columns A, B and C but what would I have to do if I had a huge document whose size and content might even change from time to time? I know that there is also an attribute ws.rows.count but this always returns a big value like 60000 even if only a few rows are occupied.So basically, I'm looking for a simple way to loop through all the used rows of an Excel file with the possibility of accessing each cell in that row.

I am trying to create a console application that allows me to read the contents of a text file and saving the data by specific name in a set of files. For example, the text file I am going to read is a tab delimited file. Some content of the file includes full name, school, location, and whatnot. I want to save the content by school name in a set of files that have the school names. In this case, everyone that attends "Central" will be saved in a file named Central.txt.Everyone that attends "Central Park" will be saved in a file named Central Park.txt.These are the sub procedures I came up with so far:
Readfile()
'Use StreamReader
WriteFile()
And I think I am on the right track of reading the text file:
Dim objStreamReader As StreamReader
Dim strLine As String
'Pass the file path and the file name to the StreamReader constructor.

how to create a function that parses the input from a textinput.Text into an array of named reading, as string, and returns the number of arrays, or perhaps a negative number if there is an error in the input.
i am looking for the answer in vb6 and vb.net.
I'm trying to write some code which parses data and then populates a listbox. I'm using the IPWorks IPPort component which basically does the reading of port 30003. The ipport1_OnDataIn event is where all the action is. I parse the data, which works great.. however when I try and do something simple such as add text to a listbox, I get the dreaded error "Cross-thread operation not valid: Control 'lstListBox1' accessed from a thread other than the thread it was created on".I've googled the error and tried copy and pasting some workarounds but nothing seems to fix the issue.
If anyone can offer help, it would be greatly appreciated. If you could possibly show the code already implemented into mine, it would be even better so I can see how it works. It would make more sense to me. My code is below. The part i'm trying to get working is the lstlistbox1.items.add("Test") in Case "2". This is to just get it working.. I'll be adding listbox items in the other cases as well, and they'll be parsed values instead of "Test". This is just to simplify things at the moment.

Is there a more elegant way to structure the following code, which takes a comma delimited string containing certain values in specific positions and assigns the values to the properties of an object?[code]...
View 5 RepliesIs this function as efficient as I can make it or can it be done more efficiently? It takes a line of text and turns it into an array of values.If the value delimiter exists inside a string delimiter, that value delimiter is incorporatedinto that value. String delimiters are removed from the values, and so is any leading or trailing white space:
Public Function ParseStringDelimiters(ByVal Line As String,
ByVal ValDelimiter As Char, _
ByVal StrDelimiter As Char) As Array

View 1 Replies2.0 Framework.Our software does some measurement and then sends the output to our charting program. Right now it is taking 20-30 seconds for the results to print after our chart has sent the data to the printer since the printer is in sleep mode. What we are wanting to do is send a command to wake the printer at the end of our test, before it sends the results to the charting program, so the printer is (hopefully) done "waking up" by the time the chart program auto prints.
I have been looking around and haven't been able to find anything regarding this. The printer we are mainly using is a Brother HL 5250DN. I have contacted Brother but I have yet to hear anything back from them.

Dim SmtpServer As New SmtpClient

The part highlighted is what im having trouble with.

Is there a way to determine if an internet connection is available before attempting to send.
Is there any workaround to the input box sending an empty string when you press cancel? I have a web research function on my program:

Basically, it provides an input box, you type in the album you want information on, and it will take you to a web page to give you information.
But when you press cancel, it does all of that anyway. It just takes an empty string...
Is there a way I can have the user press cancel to the input box and simply nothing happens? As far as I can tell, it ignores the "If windows.forms.dialogresult.ok." line...
