I have some web-radio site and i want my program to record the song name from the webpage, i dont really know how,
i made RichTextBox and i made a WebClient....
I dont know how to make it look for the string that shows the name song.
I can now navigate to pages, fill forms, submit forms, click elements etc.My next big step will be collecting html element ID's which are constantly different each time I navigate to a page.On the webpage I am working on, each page contains 10 of these ID's.
ill_btn_20234518
ill_btn_20534538
ill_btn_20174048
Now I am just looking to click on one of them at random for right now. It doesn't matter which one. Or perhaps the first one to appear on the webpage.Here is the code that I tried first........it works fine for clicking static buttons (without the random id #'s at the end)
Dim ill As HtmlElement = WebBrowser1.Document.GetElementById("ill_btn_")
ill.InvokeMember("click")
End Sub
I guess what I am looking for here is some sort of partial id tag, to let it know to search for the first ID that begins with ill_btn_ ?

I have been dabbling in VB before and i played around wiht linq to sql back then but im wondering what i should go with here.I need to have a list of people.. They should all have their own id nr.
The people in the list are supposed to keep a record of values changing over time with a datetime stamp. (In my case its numbers from a test outcome of blood)You have to be able to add people and delete people. All records will be deleted too.A Chart will read information from the records and display changes over time in chart.I was thinking of doing it with linq to sql and i was kinda aiming at Creating datatables with id names from the script
Havent found a way of creating datatables from a script though..I was hoping for a solution like that.. And i was hoping id be able to search databasetable names.
i am making a l337 speak generator..Lets say I input bob12321 (although i can input anything)I would like to make the program replace the "b" with either [code]How would i do that... I tried string.replace - but it says character A cannot be turned into long (on a seperate word)[code]

I read the following question to download a web page whose contents is coded in UTF-8. The page is then converted into a byte array, while I'm using a String to read contents from the page.
I need to turn UTF-8 into Latin1/ANSI since that's what RichText and MessageBox seem to use (I'm getting funny characters).
Is there a more direct way to donwload a UTF-8 page and convert it into ANSI/Latin1?
Edit: When callig MessageBox, accented characters are not shown as expected:
Content = CStr(e.Result)
'Théâtre, Métro
MessageBox.Show(Content)

I am reasonable new to programing and have ventured in to using VB.net after creating macro's etc in excel, as this seemed to be the easiest transition into the world of programing.I am creating a application to work with an access database and before I submit the forms textboxs to the database, I check to make sure each field is filled in and if it isn't then I highlight the field by changing the label back colour to orangered.
What I have is a bunch of textboxes and a label above each saying what the field is. so for example the textbox name is txtBox1 and its label is lblBox1, txtBox2 - lblBox2 and so on.So what I thought I would try and do is, as the user leaves the txtBox after editing, the label background colour would be changed back to transparent.
As I have multiple txtbox's I thought I could do this using sender to get the name of the txtBox on leave, strip the first 3 letters txt and change them for lbl cast it as a label, then change the background color but I cant seem to convert my string to a label control. can someone help me with what am i missing or not doing.

How do you change characters in a particular string and set them to a particular value.

View 1 RepliesMy program so far reads a certain webpage's source code and places it in a textbox. This much has already been accomplished.
Now I need to pick certain strings out of the rather large amount of text data and have the lines stored in variables, but the trick of it is, the exact string is unknown. The exact function should be, that the code finds certain tags from the source code, say <td> and </td> and takes the string data in between those tags, what ever it may be.
For example i have form within the application which shows the connection string in a text box so the user can change it to there database but i cant work out how to save the new string to the connection string within the app.config file
