Below is the code i am using to create labels on runtime, my question is how can i add tooltips to these labels?


Dim sectortime As DateTime
Dim sectors(250) As Label
Dim sectip As ToolTip
Dim seclength As Integer
Dim secposition As Integer
Dim sectorto As String


With sectors(currentlabelnumber)
                                .Left = secposition + seclength - 5
                                .Top = 131 + (k * 182 - 150 + value)
                                .Text = sectorto
                                .AutoSize = True
                                .BorderStyle = BorderStyle.FixedSingle
                            End With
                            Me.Controls.Add(sectors(currentlabelnumber))
                           
 sectip.SetToolTip(Me.sectors(currentlabelnumber), sectortime)

                            currentlabelnumber = currentlabelnumber + 1

As you can see i have tried adding a tooltip, but on runtime i am informed that object refrence not set to an instance of an object.

Any help is much appreciated.

Hi dr_dudd,

You need to add a ToolTip component to your form and call ToolTip1.SetToolTip(YourControlName, "Your tip")

Cheers!

Hi emoreau

I have already tried this.... if you look closely at the code in the question you will already see the lines...

Dim sectip As ToolTip

sectip.SetToolTip(Me.sectors(currentlabelnumber), sectortime)

Try:

                sectip= New ToolTip
                sectip.SetToolTip(Me.sectors(currentlabelnumber), sectortime.ToString)
                sectip.Active = True

dr_dudd,

but I don't think that your Tooltip as you defined it belongs to the form so the form cannot show it! Try adding a Tooltip component and use that one.
