Form1.button2.text.. is not accessible in this context because its private - visual-studio

What I would like to do is after clicking the button14 which is login it would change all the button in all forms text to "sample" I already change the class where the button2 is from private to public but I still get an error
Public Sub button14_Click(sender As Object, e As EventArgs) Handles button14.Click
If textBox2.Text = "sample" And textBox3.Text = "****" Then
Form1.Show()
Me.Hide()
button2.Text = ("sample")
Form1.button2.Text = ("sample")
Else
MsgBox("Sorry, Username or password not found", MsgBoxStyle.OkOnly, "Invalid")
textBox2.Text = " "
textBox3.Text = " "
End If
End Sub
this is form 1
Public Sub button2_Click(sender As Object, e As EventArgs) Handles button2.Click
Login.Show()
Me.Hide()
End Sub

Do people still write VB code? Anyway, the error message is quite clear. You need to make the button public (not just the class).
But, for security reasons, instead of making the button public...I would recommend you to expose a method to change the text of the button, after all, that's all you're doing. You can even mark this method with the Friend access modifier...I think it is the same as internal in C#?

My guess this is winform project.
You can change the access modifier of your button in the form designer. Select your button press F4 for the property grid, find Modifiers and change it to whatever.

Outlook add-in mailitem.display not working Visual Basic

I'm in the process of converting some outlook VBA macros to an Add-in. I am having difficulty with my macros that create emails based on a template. I decided to code a simple button to create and display a new email with the subject test.
Everything is working up to displaying the email which doesn't happen.
Private Sub ButtonGenEmail_Click(sender As Object, e As EventArgs) Handles ButtonGenEmail.Click
Me.Close()
Dim objApp As Outlook.Application
Dim objMail As Outlook.MailItem
objApp = Globals.ThisAddIn.Application
objMail = objApp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem)
objMail.Subject = "test"
objMail.Save()
objMail.Display(False)
End Sub
At one point I added msgbox "Done" after objMail.Display(False) and the message never appears.
Thanks in advance
This should obviously work. I'm not so skilled in Outlook but I guess the problem here is that you run it from a form (I see the Me.Close)
Isn't then Outlook blocking to display the mail because the form is still open (I guess modal = ShowDialog())?
I think you will have to either change the form to be not modal (use Show() instead of ShowDialog()) or handle the event after the form is closed, something like
All code below written from top of my mind, so I may miss something
A method from where you initialize the form
Dim frm as new YourForm()
frm.ShowDialog()
if frm.MyState = TheyClickOnButton Then
' Run your mailItem code here
End If
in the form code
Public Enum State
Unknown = 0
TheyClickedOnButton
End Enum
Public Property MyState as State
Private Sub ButtonGenEmail_Click(sender As Object, e As EventArgs) Handles ButtonGenEmail.Click
MyState = TheyClickedOnButton
Me.Close()
End Sub

visual basic multiple toolstripmenuitems to perform the same on click

I am new here. So apologize in advance if not wording question properly.
I am developing an application (VS2013, Visual Basic) that using multiple menu items in the MenuStrip. When item is clicked the identical function is called - the Tab is created and appropriate form is loaded.
i.e.
Private Sub XXXMNU0039_Click(sender As Object, e As EventArgs) Handles XXXMNU0039.Click
Dim f1 As New frm_B05_01_SalesQuotes
Dim imgnm As String = "XXXMNU0039"
Call XXXTabPages("Sales Quotes", f1, imgnm)
End Sub
Private Sub XXXMNU0040_Click(sender As Object, e As EventArgs) Handles XXXMNU0040.Click
Dim f1 As New frm_B05_03_SalesQuotesReports
Dim imgnm As String = "XXXMNU_Reports"
Call XXXTabPages("Sales Quotes Reports", f1, imgnm)
End Sub
....
I am wondering is there is a way to create a "global" default "on click event" for all menu items that will accomplish the same thing by default. I have all the relevant information for each menu item stored in a table and hope to avoid creating "on click" for each item.
Thanks in advance.
You could have the same handler for the click event of your ToolStripMenuItems.
Just add, after the first Handles XXXMNU0039.Click the event to handle for another ToolStripMenuItem and so on
Oviously, then problem is how to differentiate the various ToolStripMenuItem that calls the same event handler. But in the event arguments there is the Sender object that represent the current ToolStripMenuItem that has called the event.
Just DirectCast to a ToolStripMenuItem and read its name to pass the correct parameter to the XXXTablPages method
Private Sub menuItemHandler_Click(sender As Object, e As EventArgs) _
Handles XXXMNU0039.Click, XXXMNU0040.Click
Dim f1 As New frm_B05_01_SalesQuotes
Dim itm = DirectCast(sender, ToolStripMenuItem)
Dim imgnm As String = item.Name
Call XXXTabPages("Sales Quotes", f1, imgnm)
End Sub

Change text of selected textbox on button click

I've got a problem that involves, on a button click event, changing the text of the currently selected textbox on the form. Is this possible? If so how do I go about doing it?
EDIT: I do not know the name of the textbox, but it will always be the currently selected or 'focused' textbox.
The main problem is that when you press the button, the Textbox is no longer the focus.
By solution appears here, You can do this:
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
If lastTextBoxFocused IsNot Nothing Then
lastTextBoxFocused.Text = "Bla bla, bla!"
End If
End Sub
Dim lastTextBoxFocused As TextBox
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
'find all TextBox's in the Form.
For Each Ctrl In Me.Controls
If TypeOf Ctrl Is TextBox Then
'attach a lambda expression to each Enter event, to "remember" the last enter
AddHandler CType(Ctrl, TextBox).Enter, Sub(o, ev) lastTextBoxFocused = o
End If
Next
End Sub

Copy event handler assignment to another instance

I am trying to create a clone of an object instance.
Creating the new instance and copying property values is no problem but the original object instance has some event handlers assigned to its events. How can I copy event handlers to the new instance?
Thanks..
Here is a code sample...
Public Sub ButtonClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
MessageBox.Show(sender.Name + "was clicked")
End Sub
Public Sub CloneButton()
Dim newButton = New Button
newButton.Name = Button1.Name + "_Clone"
newButton.Text = Button1.Text
newButton.Width = Button1.Width
newButton.Height = Button1.Height
'Some code here to copy Button1's event handler ButtonClick,
'so when the new button is clicked "Button1_Clone was clicked" is displayed.
End Sub
This is freakin' old, I know, but I can't believe this guy didn't get an answer, it's been answered on SO before, right here.
Just one thing; in the example code given, miHandler will be Nothing if there is no event handler attached to the sourceObject, you should test for that.

ModalPopupExtender + ASP.NET AJAX: Can't page grid

I'm trying to page and sort my DataGrid which is inside a ModalPopupExtender but I can't page it in any way, already tried with <Triggers>, put the UpdatePanel inside, outside, in the middle, and it does NOT work. Modal popup does not get closed but the grid just disappears. Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
BindData()
End If
End Sub
Private Sub btnSearch_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSearch.Click
SqlServerDS.SelectCommand = "SELECT * FROM emp WHERE name LIKE '%" & txtSearchName.Text & "%'"
BindData()
End Sub
Private Sub BindData()
grdSearch.DataSource = SqlServerDS
grdSearch.DataBind()
End Sub
Private Sub grdBuscaPaciente_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles grdSearch.PageIndexChanging
grdSearch.PageIndex = e.NewPageIndex
BindData()
End Sub
Inside the Designer, this is the code h:
<modalpopupextender>
</modalpopupextender>
<panel>
<updatepanel>
<gridview>
</gridview>
</updatepanel>
</panel>
Tommy is right, so what you just have to do is re-show the popup.
After the BindData() in the PageIndexChanging event show the panel again with the Show() method of the popup extender.
This code is in c# but is pretty much the same.
gvHorarioPB.DataSource = (DataTable)Session["Prueba"];
gvHorarioPB.PageIndex = e.NewPageIndex;
gvHorarioPB.DataBind();
//mpePB is my modalpopupextender
this.mpePB.Show();
If you are using the .NET AJAX toolkit, keep in mind that each time you click someting (paging, sorting, etc.), the page performs a postback, even if it looks AJAX-y. Meaning that you will need to rebind the data each time. Try removing the IfPostback in your page load and see what that does for you.
