What do you mean by groupbox here?
A groupbox control is meant to group other controls, most of the time radiobuttons.

yah..that one...i am going to put there the english equivalent of the input word text...

Are you sure you mean GroupBox? Other than serving to group other controls (encompass, contain), and especially RadioButtons as ddanbe pointed out, I don't know how you would use a GroupBox the way you describe. Changing the GroupBox.Text is easy though: groupBox1.Text = "My GroupBox Text...";

As far as the database retrieval, more info is needed to direct you on how to do that, like: type of database (Access, Sql Server, SQLite, etc...); method of retrieval (SELECT *... or scaler query with WHERE condition, etc...). The basics steps for querying DB are:

1) Establish connection
2) Create a command
3) Execute command

but, there are specific classes for interfacing that functionality depending on the DB and type of query. You will find many examples of such data retrieval inside this forum.

ahmm okay..
but about the groupox...
my leader gave us the screenshot of our project that's why i am keep on mentioning that the english equivalent word of the other word that the user entered in the textbox will be displayed in the groupbox..the english word will be obtained in the database that was created...is it not possible?

Possible?--don't know what the screenshot looks like, but probably anything possible.... Can you attach the screenshot so we can see what you are talking about?

sorry, but how can i attach it?

ok thanks...

here it is..

the user will enter a word in the textbox particularly Tagalog word for example 'aso' then, when he clicks the speak button the software will give the spoken form of the word then the english equivalent word will be displayed in the groupbox as 'aso-dog',something like that....
