I want my button1 to change the text of my form1 from "My Application name" to "My Application name2" by the click of a button.
What I've tried:
form1.text = (textbox1.text)
But no luck.
Any Help?
If you meant about Main Form caption/text .. It has to be work with
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Text = Textbox1.Text
End Sub
You cannot can change the form name at run time. The name of a Form can be anything you want, but it must stay the same throughout. I can't imagine however why would you ever want to change the name in runtime as its not visible to the users. The form's caption on the other hand is a completly different thing, adressed in #matzone's answer.
Try just with following code:
Me.Text = Textbox1.Text
When you say change "Name" you are talking about changing the word that represents the form throughout the coding. This means it can ONLY HAVE ONE NAME because it woudl be a chaos if it had more than one.
When you say change "Text" you are talking about the "Title" of the form. The text that shows up there in the left upper corner.
To change the Name you just need to click the form on the designer and then go to properties and scroll down until you find the Name option.
You can change Text the same way or programatically writing:
Me.Text = "MyApplicationName 2"
Hope it helps.

In my application for Visual Basic, I have two radio buttons on the third TabPage. I scripted the "No" button to make a message box pop-up if you click it, but when I test it, instead of just showing the message once, it showed the same message again when I selected other option, "Yes".
I tried doing multiple things, but nothing worked. For the radio button, I did a simple line of code like this at first:
MsgBox("insert text here", MsgBoxStyle.OkOnly, "insert title here")
After I found out it appeared when you changed the selection to Yes, I tried doing this:
If RadioButton26_Select() = True Then
MsgBox("insert text here", MsgBoxStyle.OkOnly, "insert title here")
End If
Obviously, that didn't work either. In the first line of code for that radio button, I changed the RadioButton26_CheckedChanged to RadioButton26_Select:
Private Sub RadioButton26_Select(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton26.Select
That line I changed didn't have the () after the Selects, so I put the () after after all the Selects. That didn't work either.
So, I'm really confused here. Any help would be appreciated.
You want to use the RadioButton.Checked property. It indicates whether the RadioButton is "selected" or not.
You should also do it in the CheckedChanged event since that is raised every time the Checked value changes.
Private Sub RadioButton26_CheckedChanged(sender As Object, e As EventArgs) Handles RadioButton26.CheckedChanged
If RadioButton26.Checked = True Then
MessageBox.Show("insert text here", "insert title here", MessageBoxButtons.OK)
End If
End Sub
As you see I'm using MessageBox.Show() rather than the MsgBox() function. I recommend you to do so as well since the MsgBox() function exists purely for backwards compatibility with VB6, whereas MessageBox.Show() is the native .NET-way of doing it.
How can I get a variable in one xaml(when the button is clicked) to appear in another xaml in a textbox.
Basically once the button is clicked in Menu.xaml the name variable is displayed in a text box in Basket.xaml. How can I go about doing that?
Button in Menu.xaml
Private Sub VanButton_Click(sender As Object, e As RoutedEventArgs) Handles VanButton.Click
Dim Name As String = "Vanilla"
End Sub
Variable Name into Basket.xaml textbox once button is clicked in Menu.xaml
Private Sub IcecreamChosen_TextChanged(sender As Object, e As TextChangedEventArgs) Handles IcecreamChosen.TextChanged
End Sub
The app is developed in VB.NET , Visual Studios 2015. I am new to this and have no idea on how to make it work this way.
You have to give a name to your textbox and the in the button click event handle you can write yourtextboxname.Text = variabile
Anyway I suggest you to start using databinding approach. Xaml is databinding based! :)
I write this code for tab-like behavior when user presses ENTER on textboxes for every form, which works fine.
If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Return) Then
SendKeys.Send("{TAB}")
e.Handled = True
End If
However, I need to write the code once, perhaps as a sub or function in a module so that I do not have to write the same for every form. I have checked various forums including
Detecting Enter keypress on VB.NET and
Tab Key Functionality Using Enter Key in VB.Net
BUT all I get is either to write code for each textbox or for every individual form.
Has anyone tried out a single code for ALL or may be several selected forms of the application? If yes, please share with me. Writing for every form still works fine for me but i need to take advantage of OOP. Thanks
There are many ways to implement this, one of those is to create a custom textbox User Control
Adding a control to your project is very easy just right click in your project in the solution explorer ->Add->User Control
Give a name to your control ex. "tabedtextbox"
Add a textbox control to your User Control
Place the code in the keypress event of textbox1 of the UserControl
Private Sub TextBox1_KeyPress(sender As Object, e As KeyPressEventArgs) Handles TextBox1.KeyPress
If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Return) Then
SendKeys.Send("{TAB}")
e.Handled = True
End If
End Sub
Compile once in order to update the whole project with the new user control.
Goto to your form and add your new User Control, you can locate it at the Toolbox panel.
Run your program and you will see the behavior of TAB when you press enter on each textbox.
If You wish to allow the user to press enter in a TextBox, instead of pressing a specific button,
you can use the acceptbutton property.
One good way to use it, is to change the property, on the Enter and Leave events of the TextBox. That you call Click event of the Button, when User press Enter inside the TextBox.
Try this code:
Private Sub tbProject_Enter(sender As Object, e As EventArgs) Handles tbProject.Enter
Me.AcceptButton = bSearch
End Sub
Private Sub tbProject_Leave(sender As Object, e As EventArgs) Handles tbProject.Leave
Me.AcceptButton = Nothing
End Sub
Private Sub bSearch_Click(sender As Object, e As EventArgs) Handles bSearch.Click
'.... actions to perfom
End Sub

I want to be able to edit/delete/insert lines of text from a textfile by using listbox and textbox.
I want to display all the contents of the textfile per line in a listbox and when I click a line of text it will then display it in the textbox giving me the option to either edit or delete that line of text.
My insertion of text would be inserted after the last line of text being displayed in the listbox. Is this possible? I just want a starting point and I will continue it from there. Thanks in advance.
Here is an answer with a listview , button 9 is to fill Listview, listview click sends the text to textbox and button 10 saves it back to the listview
This is probably the simplest way to do what you want to achieve.
Private Sub Button9_Click(sender As Object, e As EventArgs) Handles Button9.Click
ListView1.HeaderStyle = ColumnHeaderStyle.None
ListView1.HideSelection = False
For i As Integer = 0 To 50
ListView1.Items.Add("Line number" & i.ToString)
Next
End Sub
Private Sub ListView1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ListView1.Click
TextBox8.Text = ListView1.SelectedItems(0).Text
End Sub
Private Sub Button10_Click(sender As Object, e As EventArgs) Handles Button10.Click
ListView1.SelectedItems(0).Text = TextBox8.Text
End Sub
Probably a good starting point for you anyway and expand this code from here on.
Yes. It is possible. I would suggest to use already existing text editors rather than re-inventing the wheel. If you still want to go ahead and create a new one from start, then you can try the following.
Create a window form application in vb.net with ListBox control for showing the lines, a textbox control for entering the file name, a button to browse to the given file, a button on clicking on which the file content should get loaded. Refer file objects for this.
Utilise ContextMenu class in vb.net to allow right click to read selected listbox line and accordingly perform add/delete/edit operation by modifying the selected listitem value.
Can I create a tooltip that will show up when a user moves his/her cursor over an image? I can't find such a property in Visual Studio, and I've scoured Google to no avail. I'm using an image in a PictureBox.
Here's to anyone out there on StackOverflow instead of some awesome Halloween party! Yay!
yea, for some reason the Picturebox doesnt have one.
imports System.Drawing
dim tt as new ToolTip()
tt.SetToolTip(picPicture, "This is a picture")
and dont worry, the weekend has only started, plenty of time to party.
Typically I create the interface then throw a ToolTip object from the Toolbox on to the form.
This then gives each object the "ToolTip" property (towards the bottom of the list) which can then be configured to your delight.
Drag a ToolTip control from the toolbox on the left onto your form (the designer will then put it below your form, since it's not meant to be visible normally). By default it will be named "tooltip1".
Then select your checkbox and go over to its properties window. You should see a property labeled "Tooltip on tooltip1" - set this to whatever you want. When you run the app and hold the mouse over your checkbox, you should see the tooltip text.
Assuming that you have added a picture box member with the WithEvents modifier you can use the following
Private tt As ToolTip = New ToolTip()
Sub OnPictureMouseHover(ByVal sender As Object, ByVal e As EventArgs) Handles PictureBox1.MouseHover
tt.Show("the message", Me)
End Sub
Sub OnPictureMouseLeave(ByVal sender As Object, ByVal e As EventArgs) Handles PictureBox1.MouseLeave
tt.Hide()
End Sub
