I want to show a tooltip every time I hover a graphics object. I used a bitmap to draw a graphics object in the picture box.
Picturebox does not have a tooltip feature in visual studio, not that i know of anyway. Here is a work around.
imports System.Drawing
Dim varname as new ToolTip()
varname.SetToolTip(PictureBox1, "Tooltip data here")
If you have added the box with WithEvents then use the following code
Private tool As ToolTip = New ToolTip()
Sub OnPictureMouseHover(ByVal sender As Object, ByVal e As EventArgs) Handles PictureBox1.MouseHover
tool.Show("Tooltip", Me)
End Sub
Sub OnPictureMouseLeave(ByVal sender As Object, ByVal e As EventArgs) Handles PictureBox1.MouseLeave
tool.Hide()
End Sub

In my code when the form loads I am trying to create a picture box inside of the form. When the code that includes the picture box in the form is deleted the picture box appears just fine but when I add that code back in it no longer is viable.
Here is my code:
Private Sub frmMain_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Dim picAlien1 As New PictureBox
Me.Controls.Add(picAlien1)
picAlien1.Size = New Size(24, 16)
picAlien1.Location = New Point(pnlRow1.Location.X, pnlRow1.Location.Y + 8)
picAlien1.Image = Space_Invaders.My.Resources.Resources.alien_1_phase_1_pixilart
pnlRow1.Controls.Add(picAlien1)
End Sub
My DataGridView have some columns I want to turn a different color to indicate that they are auto-fill columns and does not need user input.
So I created the code to color columns:
Private Sub autocolumn()
Dim auto_cell As New DataGridViewCellStyle
auto_cell.BackColor = Color.LightSteelBlue
ProjTable.Columns(3).DefaultCellStyle = auto_cell
ProjTable.Columns(5).DefaultCellStyle = auto_cell
ProjTable.Columns(9).DefaultCellStyle = auto_cell
ProjTable.Columns(10).DefaultCellStyle = auto_cell
End Sub
And then place it into form Load event
Private Sub projectentry_Load(ByVal sender As Object, ByVal e As EventArgs) Handles MyBase.Load
autocolumn()
End Sub
On testing the form, the first row is colored no problem. Issue is on the 2nd row the color is white. Then the 3rd row its colored, and thee following white. And it follows this repeated pattern.
I even tried to make a DataGridView Rows Added event to call the sub
Private Sub color_load() Handles ProjTable.RowsAdded
autocolumn()
End Sub
Again same result. What may be the problem here?
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
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
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.
