Using VB.Net
2 textbox in the Form (textbox1.text, textbox2.text)
Once user entered the value in the textbox1 means automatically textbox1 value should appear in the textbox2 without clicking the buttons.
In which event i have to write a code instead of button clicking event....
Need vb.net code Help
Try this..
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
TextBox2.Text = TextBox1.Text
End Sub
Every time you type a value in textbox1 it will appear in textbox2

I'm using a VB.NET form that contains two panels; I want the user to be able to enter a string value in a textbox on panel 1, and have it appear in a label in panel 2.
Basic Example:
Private Sub TextBox1_KeyUp(sender As Object, e As KeyEventArgs) Handles TextBox1.KeyUp
Label1.Text = TextBox1.Text
End Sub
Don't worry about whether or not they're in different panels.
I have the following:
a listbox called ListBox1 with a couple of random values in it
a couple of rich textboxs called Rit11 up to Rit 154
a button
When I click a rich textbox, I want to set the a variable to the number that the box is called. After this I select a value from the listbox, and when I press the button, I want this value to move to the selected textbox, and be removed from the listview. I made the following code, but it gives an error.
Private Sub Rit12_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Rit12.Click
SelBox = "12"
End Sub
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim BoxName
BoxName = ("Rit" & SelBox)
Me.Controls(BoxName).Text = ListBox1.SelectedItem
ListBox1.Items.RemoveAt(ListBox1.SelectedIndex)
End Sub
It worked fine, till I tried using the variable name. This rule seems to give the problem:
Me.Controls(BoxName).Text = ListBox1.SelectedItem
Example what i want so if i type some keywords to textbox i do not it remove text from textbox
when click on listbox and add that selected item to textbox but only after keywords and do not remove them both just leave as it is ?
How can you do that ?
this is code i have for so far.
Private Sub ListBox2_SelectedIndexChanged(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles ListBox2.SelectedIndexChanged
TextBox1.Text = ListBox2.SelectedItem
End Sub
Thanks.
Private Sub ListBox1_SelectedIndexChanged(sender As System.Object, e As System.EventArgs) Handles ListBox2.SelectedIndexChanged
TextBox1.Text += ListBox2.SelectedItem
End Sub
Add the plus sign before equals to the += sign is an Add AND assignment operator, It adds right value to the left value and assigns the result to left value
I have created the text box, and the generate button.
when I click on the generate button, I want it to display a text box with numbers. How do I do so using the event handler?. Sorry, basic question.
If all that you are trying to do is to set the value of a text box when a button is clicked, then you can do it like in the following example. You'll have to replace the names of the controls with whatever you have called them:
Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
Static count As Integer = 0
count += 1
Select Case count
Case 1
TextBox1.Text = "123"
Case 2
TextBox1.Text = "345"
End Select
End Sub
First, drag a TextBox from your tool box, then double-click on your button and edit your Button1_Click method, like this:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
TextBox1.Text = "12234234234"
End Sub
Ok Here is what I have so far. I am trying to do the checkbox so that way only one is check at a time. But for some reason they both will check. And another thing I have the labels on there but in the radiobuttons no matter which one you check and submit it only stats the bottom one. Can someone help me and tell me what I am doing wrong...
Public Class Form1
Dim Message As String
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load, MaskedTextBox1.TextChanged
End Sub
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
If TextBox1.Text <> "" Then
ErrorProvider1.Clear()
Label1.Text = TextBox1.Text
Else
ErrorProvider1.SetError(TextBox1, "Please enter text")
End If
End Sub
Private Sub MonthCalendar1_DateChanged(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DateRangeEventArgs) Handles MonthCalendar1.DateChanged
Me.Text = Me.MonthCalendar1.SelectionRange.Start.ToShortDateString
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Label2.Text = MaskedTextBox1.Text
Label3.Text = RadioButton1.Text
Label3.Text = RadioButton2.Text
Label3.Text = RadioButton3.Text
Label4.Text = CheckBox1.Text
Label5.Text = CheckBox2.Text
Label6.Text = MonthCalendar1.Text
Dim message As String
message = ""
If CheckBox1.Checked Then
message += "first one clicked"
End If
If CheckBox2.Checked Then
message += " second one clicked"
End If
MessageBox.Show(message)
End Sub
Private Sub RadioButton1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton3.CheckedChanged, RadioButton2.CheckedChanged, RadioButton1.CheckedChanged
Dim radMessage As RadioButton = CType(sender, RadioButton)
If radMessage.Checked Then
Message = radMessage.Text
End If
End Sub
End Class
Ok and this is suppose to be what my commands are suppose to be doing..
Create a new window Project .change the title of the form to Lab3.drag the following controls to your form,textbox,masked textbox (set to phone number),3 radiobuttons in a groupbox(container control),2 checkboxes, Month calendar,all on the left of the form,add a label for each control on the right, add an errorprovider for the textbox and insure it has data entered, add tooltips to every control, add a button
Task
When the user mouses over any control on the left they get a tooltip, change the text on the button to "Submit", when the user clocks the button, the info from the controls on the left appears in the label on the right,if no data is entered in the textbox use the errorprovider control to prompt the user for data, only use 1 label for all three radiobuttons, Only display each check box data if the check boxes checked, make sure to add code to erase the appropriate label if the user UNCHECKS a check box, set the tab order of the controls so you can tab though them in order down the left side, look on the internet to find out how to rettrieve the selected date from the calendar control when the user clicks the button.
I am not expecting anyone to do this for me. I am trying to do the code but i know i mest up some where. I am still a newbie at this so sorry.
I don't expect this answer to solve all of your problems but hopefully it should prove a starting point.
Firstly, why do you want only one checkbox to be selected at any moment? I can't see that as a requirement in your task? By default checkboxes do not exhibit that behaviour (that is what radio buttons are for), but they can be made to. To do this you would need to look at the selected_change event of the checkbox and when one is selected, deselect all the others. However before you do that, make sure it is what you are after before progressing.
With the radio buttons issue, I am assuming you want to set the text of the selected radio button into a label? Well currently you are assigning the selected text into a field, Message, but you are not using this anywhere else. When you set up your labels you have the following:
Label3.Text = RadioButton1.Text
Label3.Text = RadioButton2.Text
Label3.Text = RadioButton3.Text
Whereas I am guessing you need something along the lines of
Label3.Text = Message
At the moment you are setting the same Label text three times and only the third radio button text will be displayed.
On another note I would possibly think about using different variable names that Message as it could result in some confusion later on.
Hope that gets you somewhere
