VS 2008 Return Variable From A Webpage?
Apr 7, 2009
excuse my stupidness, i'm fairly new to VB and i've only done a little bit with it before. Basically i am making a little application that i want to run on my machine. Standalone not via a web browser.I have a web page which is generated using php, there is no html code on the page simply a number, e.g. "9995" when you view source.
All i want to do is return this value from the web page (without actually opening the page in a browser) and display it in a text box in VB or store it as a variable that i can use later. point me in the correct direction or right keywords to research, or if you have a simple example that would be even better

I am writing a program with multiple forms (for inputing loan/financial information - so they are set up exactly the same albeit a form number (ie: 1-6)) that feed into a summary page form to display each individuals form's information. When the user closed a financial form, it then feeds the information to a summary page using the code I have below: [Code]. I am new to working with functions, and have not been able to find anything that can show me how to fill multiple textboxes with them (I only know how to return a variable using the function to work a calculation). Any way that I can write a function (or any other call) for this would save me a tremendous amount of coding, and make debugging worlds easier.

When i press the button3, i want the webbrowser change site after how mutch the clock is. Is the clock between 9:00 and 17:30, the webbrowser is gonna change to swedish sites. If the clock is between 17:31 and 21:30, the webbrowser is gonna changes to american sites. But the webbrowser is only choose ONE swedish site and ONE american site.

I am making an application that will save all the names of the movies in my "movies" folder on my computer. I am able to make a list of all the names quite easily, but how would it be possible for me to search The Internet Movie Database (IMDb) for the title of the movie, click on the link of the name of the movie and grab information of the movie off the imdb database (Run time, rating, and plot?)

I decided it's time to migrate from VB6 to VB.NET and am currently translating my radio player but have run into several issues so I might be on this forum for the rest of the day... Anyway, in VB6 I used Inet to get the source of a PHP page that had the current song that was playing on the SHOUTcast stream. I can't seem to get Inet to work and figured I would just look for another method so I wouldn't need to pack msinet.ocx along with the finished product.
How can I get the source of the PHP page and store it in a variable or textbox/label.

This is my simple code that calls a function from a class I created called "clsNetwork". The function simply pings a computer from a computername I pass it and returns the results.
Dim PingStatus As String
PingStatus = clsNetwork.PingComputer(ComputerName)
txtbox.text = PingStatus

I was wondering if there's a way I can make my objects return their own variable name as a string, something like this:
Public Class MyClass
Public ReadOnly Property VariableName() As String
Get
[Code]....
Is this possible? I'm fairly sure it should be possible through the System.Reflection namespace, but I can't figure it out.

I wrote the following two functions in a class to take a gpib reading and also take a measurement from an LCR meter.
HTML
Public Function gpibRead(ByVal Channel As Integer, ByVal buffer As Integer) As String
Dim readingBufferA1 As String
Select Case Channel
Case 1
readingBufferA1 = gpibLCRA1.ReadString(buffer)
Return readingBuff
[Code] .....
When on the main form I call the funtion takeMeasurement(1) how can I get the LCR readings back. If I try and use readingBufferA1 on the mainform it doesn't recognize that as a variable. I know that it is taking the reading and storing the correct numbers because I am monitoring on NI Spy.

Can't seem to figure out how to use a function return variable in global Dims[code]...
I have also tried adding "FixPath()" under Sub On_load() but got same result. Also the reason I have to have these global is because I have around 30 Subs that refer to "Path" Variable.

Say I've got the following variables:
Public Shared x As String = "100"
Public Shared y As String = "text"
Public Shared z As String = "something"
[Code]....
But this doesn't do what I want, naturally. What I want is that my function giveVar returns the value of the variable that holds giveVar. For example I call giveVar("x") I want my function to return "100".
Of course this can be done by a Select Case but thats not what I like to do. Is it even possible to call a value based on a string?
[edit:]
Namespace i18n
public NotInheritable Class Settings
Public Shared LanguageCode As String
[Code]....
I think this works so far, BUT I get the following error on the CallByName(Me, varName, vbGet) at the Me : "me is only valid within an instance method"

When trying to register a new user on the server, the server will post back messages such as "OK" and "usernameTaken". Upon comparing this returned string with another string (to perform an action based on the returned value), the compare isn't working.
Dim backupX As New CBackup
backupX.startSocket("127.0.0.1", 8888)
Dim str1 As String = backupX.registerUser("user1", "testpass")
Dim str2 As String = "usernameTaken"
[code]....
Looks to be like the socket code is working just fine.. each Function returns the corresponding Functions' Return value (registerUser -> SocketSendAndReceiveMSG -> sendAndReceiveMSG -> receiveMSG).

It's often the case that I can write a nice tight little VB.NET function, and when it comes time to do the Return statement, it's really natural to just return the result of a quick calculation or a method call. However, this makes it difficult if I need to step through the debugger to see what is going to be returned from that Function. For example, take this simple method to illustrate the concept[code]...

What's best practice (in VB.Net):
Function GetSomething() as String
GetSomething = "Here's your string"
End Function
or
Function GetSomething() as String
Dim returnString as String = "Here's your string"
Return returnString
End Function
Obviously, neither of these implementations make any sense, but they're just meant to illustrate my point. Is there anything to be gained by using GetSomething itself to store the return value instead of declaring returnString locally and then returning that (does it avoid having an extra string allocated/instantiated - and if so, are there any performance/memory benefits)?

I am trying to use the value of one variable to call another variable of the same name.I have 2 variable one called VAR1 and VAR2.
The variable VAR1 has a value of "VAR2"
The variable VAR2 has a value of "HELP"
I want to be able to get the value VAR2 from the variable VAR1 I have defined the value of VAR2 early in the code and now I want to call that value by using the value of VAR1.The reason I am doing it this way as I have a list of 50 variables that are pulled from one system. Each of these variables have the same name as the columns of a spreadsheet. The total number of Variable stay the same but the total column headers may vary each time. I need to loop through each of the column headers match them with the variable names and add the data to the spreadsheet.
VAR1 = "VAR2"
VAR2 = "HELP"
i =1
[code]....
This is the tricky bit...if the value of the cell(1,i) = "VAR2" How do I get it to display the value of the variable of the same name In this case how will I get it to display "HELP" when I only have from the VAR1 value "VAR2" I know my code will bring back the value as a string but I want it to bring back that string as a variable and display the value of that variable?
