Re: How to change Language?

You factor out all of your display strings into a config file, and then create a different file for each language. Then, once your code selects what file to get it's values from, it's just going to work everywhere.

A different solution could be:
- Use the visual studio designer to localize the form (search for "localizing vb.net forms" on google)
- Then set the System.Thread.CurrentCulture to the value you want in the combobox selection changed event.
- On every control you could reapply the localized resources: (translated to vb.net, not compiled so it may contain some small errors)

<br />
Dim resources as System.ComponentModel.ComponentResourceManager = _<br />
    new System.ComponentModel.ComponentResourceManager(GetType(YourForm))<br />
For Each c as Control in Me.Controls<br />
    resources.ApplyResources(c, c.Name)<br />
Next <br />

I am doing a recent files menuitem. I am using a zero based array of 4 items, which i have displayed everytime you load the form. The problem i have now is, how do i limit the datafile to 4 entries? i can append the data file, but thats it. Any suggestions would be most welcome.

Well, just count how many entries you have, and once you have four, you drop one from the bottom when you add one at the top.

How do you store them ?

Hello,
I am new to visual basics and I am taking a class in it. I am trying to write a code for this and I am so confused on what to do. If anyone could help I would appreciate it.
Here is the question in my book:
Write a program that requests a complete phone number in a text box and then displays the area code in another text box when a button is pressed.

Thanks if you can help.. WTF | :WTF:

I am able to put the phone number in my text box, but when I push the button for it to extract only my area code it doesnt do anything. Here is my code:

Private Sub btnPush_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPush.Click
Dim txtPhone As Double
Dim xxx As Double
Dim xxxx As Double
Dim phone(11) As String

txtPhone = CDbl(xxx) & (xxx & xxxx)
phone(11) = CStr(xxx) & (xxx & xxxx)
phone(3) = CStr(xxx)

This is pretty strange code. How dod you expect it to extract anything ? It declares an double, does not assign a value, then does some things that will achieve nothing.

You need to use a regular expression, or the string methods that extract substrings.

Forgive me, but I know that otherwise I wouldnt be writting in to this forum. Smile | :)

I changed it to this: this is better but it still is only giving me "xxx" instead of the input of the phone number:

Private Sub btnPush_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPush.Click
Dim txtPhone As String
Dim phone(11) As String

txtPhone = CStr("xxx - xxx - xxxx")
phone(11) = CStr("xxx - xxx - xxxx")
phone(3) = CStr("xxx")
btnPush.ToString.Substring(0, 3)
txtArea.Text = ("xxx")

This code is useless. Get rid of it. why do you need an array of strings ?

buzz5958 wrote:

This code gets a string from a button ( presumably 'Button' ) and returns a substring ( presumably 'But' ).

buzz5958 wrote:
txtArea.Text = ("xxx")

The brackets in this code are superfluous, and this code sets the area code to be three x's.

It seems to me that you're wildly guessing, which is both not going to work, and not going to teach you anything if it manages to. You've got the substring method, so what do you want to get the substring of ? I assume you have a control which contains the phone number ( txtPhone is a good name for this control ). It has a Text property. This gives you the entered string. If you're allowed to assume a very specific input format, then the Substring method, on the text property of this control, will return the area code.

In future, I recommend you read through your textbooks and try to understand the process, instead of making wild guesses.

Yep. Why do arrays of strings?

Sounds like the OP is pretty new to this stuff and that would be too much for him.

Well, at that point, I was keen to give a full answer, he may well have said 'Oh, regex, yeah, I googled that and found Expresso and it helped me build what I needed'. that doesn't seem so possible, now....

When I was first learning, I'd have made a note that regex was a better solution, gone with what got me through the day, bought a book on regex and learned it.

Yes, I am sorry but I am new to all of this and the string thing just doesnt make since to me at all. I just thought that I might get some help to understand. I am taking an introduction to programming using Visual Basic 2005 and I am only in my 3rd week of the class. I did read the chapter, I just don't understand. Maybe I am trying to over think the process.

Thanks for all of your help,

Hey, it happens to all of us (well, those of us who will admit it). If you know that the area code is in a standard format such as (xxx) xxx-xxxx, you can always use the SubString method to pick out the area code. Once you have mastered working with strings, look at regular expressions as Christian said. They are really powerful and advanced Smile | :)
