ToolTips not being displayed when using an existing ActiveX control in a .Net Form

We have an existing ActiveX control that plots data points over an
image. When the mouse is moved over these points, a tool tip is
supposed to be displayed indicating information about the point.

This control is already deployed in an unmanaged application and works
correctly there. We have been attempting to re-use it in a .Net forms
based application and have gotten all other aspects to work except the
tooltips.

The ToolTips simply do not display when the control is hosted in the
ActiveX form.

Using Spy++ we can observe the message exchange betweeen the control
window and the tool tip control window. As near as we can tell, they
are identical. In the .Net app, we definitely get the WM_NOTIFY
messages for text request and pop.

I haven't found anyone reporting a similar issue, so I'm not sure if I
am doing something wrong or just something bizzarre.

Thanks for any insight,
A

I'm working on a C# Windows Forms application that is leaking memory. I've been using the SciTech NetMem Profiler 2 (A really great tool, BTW) to track down leaks. I've found one related to ToolTips that I've been unable to fix. We have a base form, from which we add and remove panels. When created, the panels create tooltips which they associate with themselves. When removed, the panels and their tooltips are Disposed. The disposed...

Hi All, Does anyone know if and how can someone add tooltips for controls contained in an UserControl ? I see that even if the control has this property, it is not working. The usercontrol is somehow blocking the appearence of the tooltip. And, is there any way I can show the tooltip, even if the control is disabled?

I am using the AxWebBrowser control to display a simple HTML page on a windows form. I want to display tooltips using the title attribute for the hrefs. The tooltips work fine when the HTML is displayed in IE and FireFox, but they don't work at all inside the AXWebBrowser. Does anyone know if tooltips are not supported, or is there a property on the control that needs to be set? Or maybe something else I am overlooking? Any help is...

Hello all, I've created a custom control that draws a monthly schedule (using the Draw function in C#). Basically it draws 31 boxes and writes the day number in every box. This works great. But I now want to show a different tooltip for every day. For now I found out that I can add a tooltip for the entire custom control

Hi all, Using the toolbox I added a tooltip provider to my form, and set the text for each of my buttons using the properties window. When I first show the form using .showdialog the tooltips work. However if I close and re-open the form the tooltips are no longer displayed. Am I missing something obvious or is this a bug ??

How do you set the tool tip property on a button. This was easy in VB6. Here is the code I am trying to use. Dim toolTip1 As New ToolTip() ' Set up the delays for the ToolTip. toolTip1.AutoPopDelay = 500 toolTip1.InitialDelay = 100 toolTip1.ReshowDelay = 50

I have an issue where I have a user control that is launched into a floating form. At some point later, I allow the user to "unfloat" the user control by reparenting it on a split container in another form. Problem is if I wake a tooltip when the window is floated, and then try the same thing when it is reparented, the app crashes with " Cannot access a disposed object.Object name: 'Form'. Presumably, this is a result of the tooltips...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
