VBForums Visual Basic Visual Basic .NET Make textbox announced after a push button is clicked Nov 14th, 2009,06:57 PM #i Thread Starter Member Make textbox appear later on a button is clicked Hi How practice I make a textbox appear inside rich text box by clicking on a push button. I want the new textbox to appear where the cursor is Thank you Nov 14th, 2009,07:08 PM #two Re: Brand textbox announced after a button is clicked Maybe by explaining to us what you are trying to do, we tin can provide a better solution. For at present, as far as I know, you can't place a TextBox within of a RichTextBox because it is non a container.

November 14th, 2009,07:23 PM #3 Re: Brand textbox appear after a button is clicked I very much doubt that you actually want a TextBox to announced inside a RichTextBox. Presumably yous want the text that is in the TextBox to be added to the text that is in the RichTextBox. For any control derived from TextBoxBase (TextBox, RichTextBox, MaskedTextBox, etc.) yous only set the SelectedText property to insert text at the current caret position. If text is currently selected information technology will be replaced. E.g. vb.internet Code: myRichTextBox.SelectedText = myTextBox.Text Nov 14th, 2009,07:27 PM #four Thread Starter Member Re: Make textbox appear afterwards a button is clicked Originally Posted by weirddemon Perhaps past explaining to united states what you are trying to do, we tin can provide a better solution. For at present, equally far every bit I know, you tin can't place a TextBox inside of a RichTextBox because information technology is not a container. I want to make a program that allows to utilise maths symbols etc hands. For example for now it has 3 buttons, 1 which allows to enter sqrt symbol, one with powers, and one with fractions. So I desire two textboxes to announced (one on top of the other) in one case the fraction push button is clicked so that its easy to type in the numbers Nov 14th, 2009,07:48 PM #5 Re: Make textbox appear after a button is clicked Well, that but goes to show that a complete explanation is required, considering my assumption was incorrect. I just did this and it worked OK: Code: Public Class Form1 Individual Sub Button1_Click(ByVal sender As Arrangement.Object, ByVal e As System.EventArgs) Handles Button1.Click With Me.TextBox1 .Articulate() .Location = Me.PointToClient(Me.RichTextBox1.PointToScreen(Me.RichTextBox1.GetPositionFromCharIndex(Me.RichTextBox1.SelectionStart))) .Show() .BringToFront() .Select() End With End Sub Private Sub TextBox1_Leave(ByVal sender As Object, ByVal e Every bit System.EventArgs) Handles TextBox1.Leave Me.RichTextBox1.SelectedText = Me.TextBox1.Text Me.TextBox1.Hide() Terminate Sub End Class When the Button is clicked the TextBox appears and when information technology loses focus the text it contains is inserted into the RTB. EDIT: Note that I added the TextBox to the form commonly and set up its Visible belongings to False. I would also advise setting the Tab gild such that the RTB follows the TextBox. That way, when you're entering text into the TextBox you can but striking the Tab central and the TextBox will disappear and the RTB will have focus.

EDIT: Notation that I added the TextBox to the class normally and gear up its Visible belongings to False. I would also suggest setting the Tab lodge such that the RTB follows the TextBox. That way, when you're entering text into the TextBox you lot tin just hit the Tab cardinal and the TextBox will disappear and the RTB will accept focus. Thanks for the long code, but it doesnt work. It just clears all the text in the RTB Nov 14th, 2009,08:xviii PM #7 Re: Make textbox appear afterwards a button is clicked Originally Posted past oyeioyei Thanks for the long code, just it doesnt work. It just clears all the text in the RTB I tested it myself before I posted it and it works in VS 2008. Either you've done something wrong when implementing it for yourself or else you have selected all the text in the RTB first and then you lot haven't entered anything into the TextBox. Setting the SelectedText will replace the current selection. If nix is selected then the new text is inserted simply if something is already selected then information technology will be replaced. If the entire contents of the RTB is selected when the TextBox is shown and and so no text is entered before the TextBox is hidden, the entire contents of the RTB will exist replaced with an empty cord. Feel free to adjust the lawmaking equally you run across fit but, every bit is, it does exactly what it's supposed to do.

Feel free to suit the code as you run across fit only, as is, it does exactly what it'southward supposed to practise. That is the thing, I have never used this kind of code before and when I was implementing information technology I just did it the way I constitute best even though I have no thought what it is. Dont empathise this code at all. Equally i said i am new to this so please Conduct with me. The code...

Nov 14th, 2009,09:04 PM #11 Re: Brand textbox appear after a push is clicked You tin merely do in a RichTextBox what is supported past the RTF specification. It basically just supports text, but allows you to add together markup to format the text with different fonts, colours, etc. What you're talkingabout goes beyond what RTF, and therefore the RichTextBox control, supports. If you want to display fractions like that and so yous'd have to employ GDI+ to describe them yourself because they cannot be represented that way in RTF.
