Hello

I have a problem whereby I wish to setup a custom tooltip. I have the code attached to do this, it all works very wel
if you have the following code in a button click event on the form

toolTip1.SetToolTip(BtnProjSearch, "Search for a Project"
toolTip1.SetToolTip(cboSelect, "select the number of projects that you wish to select"
Dim tp As New CustomTi
tp.CustomBalloon(toolTip1

However the user shouldn't have to click on a button in order to see all the tooltips

I can't put the code in the form_load event because it doesn't work there, this is because I have the following code in my
New event, particular the calling of another form which is the database connection form

Public Sub New(
MyBase.New(

InitializeComponent(

Dim c As Component = M

Dim Myform As For
Myform = New FrmAnotherFor
Myform.Show(

End Su

Any ideas as to how I could run the tooltip code so that the tooltips will appear as soon as the form is loaded without the
user having to click on any buttons

Thanx in advanc

Hi David,

(Sorry for my blank posting...eager trigger finger.)

It sounds like you are leaning toward creating your own inherited ToolTip
class. However, an easier solution (conceptually) may be to just add labels
to your form. You can easily display them as ToolTips by decreasing the
font size, changing the backcolor, and setting the BorderStyle to
FixedSingle.

Take care,

Eric
