VB.NET ToolTip Not Showing
Hi
I have an MDI Application and I show another form from a dropdown menu as follows:
Dim MyForm As New FrmMyForm
MyForm.MDIParent = Me
MyForm.Show
FrmMyForm has a ToolTip control in its Component Tray. I use the appropriate ToolTip Property of a Button Control and insert the necessary text representing the ToolTip. When I run the application and hover the mouse over the Button control, the Tooltip does not display.
Any idea what I can be doing wrong.
Thanks
He can Put Your Code (@Dhaest) also in his FrmMyForm Load Event

Hi Dhaest
I am not sure what you mean by the "Code Behind File". However I used your code but instead of the Button_Click Event I used the Button_MouseHover Event. It works, but the ToolTip just flashes and dies. In other words there is no delay. I have the AutoPopDelay set to 5000. Even if I increase it, the Tooltip just flashes by (like a flash of lightning).
Any further ideas.
Thanks

did you try in from load event?

Hi
I tried this code in the form Load Event as you suggested (because I thought it would be much less work for me).
ToolTip1.SetToolTip(Button
There is no evidence at all of the ToolTip when I hover the Mouse over the Button.
Thanks
Where do you put your tooltip?
you should add a tooltip also in your FrmMyForm design to have a tooltip text in your button

Hi itoutou
I think I have mentioned that I dragged a ToolTip control from the ToolBox onto FrmMyForm and it sits in the Component Tray of FrmMyForm. Lets call it MyToolTips. I hope I am responding correctly to your last comment.
Thanks.

yes you are...
Private Sub FrmMyForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.ToolTip1.SetToolTip(But ton1, "i am a tooltipMessage")
End sub
Private Sub FrmMyForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.ToolTip1.SetToolTip(But
End sub
just for testing purposes try :
Private Sub FrmMyForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.ToolTip1.IsBalloon = True
Me.ToolTip1.SetToolTip(But ton1, "i am a tooltipMessage")
End sub
Private Sub FrmMyForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.ToolTip1.IsBalloon = True
Me.ToolTip1.SetToolTip(But
End sub
You might want to just confirm that you can start a new project add a tooltip control and a button to the form. See if the tooltip appears...
If you see the tooltip in the simple project you just made it's something else in your project affecting the tooltip behavior.

Hi
In my initial problem statement, I provided the following code:
Dim MyForm As New FrmMyForm
MyForm.MDIParent = Me (A)
MyForm.Show
It is the line of code in (A) that is causing the ToolTip Control in FrmMyForm to misbehave. When I comment that line, all is well. However, when FrmMyForm is displayed and I click on any Menu Item of the MDI Form, then FrmMyForm is minimized . So I corrected an instance of misbehaviour and created another unique instance of misbehaviour.
Do you have any ideas or shall I close this question and create another.
Thanks
ususally the mdi parent use this :
Dim ChildForm As New yourformname
' Make it a child of this MDI form before showing it.
ChildForm.MdiParent = Me
m_ChildFormNumber += 1
ChildForm.Text = "Window " & m_ChildFormNumber
ChildForm.Show()
with one you will not have a problem
Dim ChildForm As New yourformname
' Make it a child of this MDI form before showing it.
ChildForm.MdiParent = Me
m_ChildFormNumber += 1
ChildForm.Text = "Window " & m_ChildFormNumber
ChildForm.Show()
with one you will not have a problem
it is another subject but just keep this function when you are using mdi parent
Private Function IsOpen(ByVal nameForm As String) As Boolean
Dim childfrm As Form
Dim strName As String
Dim intLastIndex As Integer
For Each childfrm In Me.MdiChildren
strName = childfrm.GetType.ToString
intLastIndex = strName.LastIndexOf(".")
strName = Mid(strName, intLastIndex + 2, Len(strName) - intLastIndex)
If LCase(strName) = LCase(nameForm) Then
childfrm.BringToFront()
Return True
End If
Next
Return False
End Function
Private Sub ShowNewForm(ByVal sender As Object, ByVal e As EventArgs) Handles NewToolStripMenuItem.Click, NewToolStripButton.Click
If blnActive = IsOpen("YourFormName") Then
Dim MyForm As New YoutFormName
MyForm.WindowState = FormWindowState.Normal
MyForm.MdiParent = Me
MyForm.StartPosition = FormStartPosition.CenterScreen
MyForm.Show()
End if
End Sub

Hi itoutou
I have tried this code, but m_ChildFormNumber is being underlined (presumably not defined).
Thanks

I have copied your code into my MDIForm but am battling to understand it. I would like to try it though.
Can you please explain the following to me:
1. How is the Sub Procedure activated. I notice that "Handles" references more than one event. The First being the Menu Item I click. I am not sure what the other event is all about because I have to substiitute something for it viz. NewToolStripButton.Click
I would love to know how it works before I try it.
