Forms :: How To Capture Mouse Enter / Leave Commands

Nov 21, 2009

I want to have a counter that measures when a mouse enters/leaves a form. To that extent I used the .mouseenter/.mouseleave commands. This works to an extent. The problem is that moving the mouse over any controls inside a form count as existing it- I don't want this. Is there a way to define the controls as a part of the form? Meaning- if the mouse was over one of my labels- it would count as being within the form. A less elegant way to measure form access could be to use the form positioning, and define capture any mouse movement within it.

Process Mouse Enter/leave At The Form Level?

Jul 18, 2012

I have a form that consists of only a TableLayoutPanel (which fills the entire form) containing a vertical stack of buttons. The resulting app is used in conjunction with another app. What I would like is to have the vb app do something when the mouse enters the form. Unfortunately, all mouse enter/leave events are trapped by the panel or the buttons.

As a quick test I created a form with a tablelayoutpanel (docked to fill the form) containing one button. I added the following code:
Private Sub Form1_MouseEnter(sender As System.Object, e As System.EventArgs) Handles

Mouse Hover And Mouse Leave To Open And Close The Window Form

Nov 5, 2009

how to raise the mouse leave and mouse hover events for VB when i place my mouse cursor over the button.

When my mouse cursor is over the buttons, it will raise the mouse hover event and open the form, then when the mouse leaves the button, it will close the form upon raising the mouse leave event.

but currently, When i excute this two events, the for will open and close very,very fast. so fast that it is like spamming the VB.

So i am wondering how to change the code that i have to excecute the event one time every time the mouse is over the button which is created at run time.

the codes to execute these two events are:

Private Sub Button_MouseLeave(ByVal sender As System.Object, ByVal e As System.EventArgs)
For Each ctl As Control In PictureBox1.Controls

Mouse Hover And Mouse Leave To Open And Close The Window Form?

Nov 12, 2009

[URL] I have tried heslacher's method which is Hi clzanas, you problems had been the result of calling a for each loop inside the events. If you only want for the button you hoover / leave to call the ShowDetails.Open/close, then you can take the code below:

Private Sub Button_MouseLeave(ByVal sender As System.Object, ByVal e As System.EventArgs)
If TypeOf sender Is Button Then
ShowDetails.Close()

[code]....

But i got the same results as my previous code, resulting in the form opening and closing so fast that it is like spamming the window.

Leave And Re-enter A Control To Make It Pop?

Dec 16, 2010

way to "reset" a tooltip, so you don't have to leave and re-enter a control to make it pop? I have a form that is pretty much entirely taken up by one control. I want to have its ToolTip text change based on which region of the control is being hovered over (which I can do now). I just have to leave the control and re-enter it to make it pop. I'd like to have the Tooltip pop, then if I move the mouse to a different location (still inside the control's bounds) have it pop-able again in the new spot.

Capture [Enter] Key Event

Apr 29, 2010

Ok, so this is VERY simple to do IF I was working with a regular Textbox control. But of course, Microsoft does not have an "AcceptsReturn" property for a MaskedTextbox Control.

So, if the user finishes typing in the MaskedTextbox control and hits the [Enter] key.... How do I capture that key stroke with this type of control? Also, what if this MaskedTextbox is on a UserControl, not a regular WindowsForm?

Capture The Enter Key When The Combo Box Has Items In Its List

Aug 25, 2010

I have been using the combo Box keypress event to capture the enter key when it is being pressed by the user within the combobox. The combo box style I am using is Drop Down. When there are no items in the combo box list the keypress event will capture the enter key. When I add any items to the list portion of the combo box the keypress event not longer captures the enter key. How do I capture the enter key when the combo box has items in its list.

Forms :: Leave Not Being Triggered On Buttonclick (cursor Is Not Moved)

Oct 5, 2010

I am having a problem where I am on a text box and try to click a button that will bring up some reports. Since my cursor is still on the text box it doesn't go through the "Leave" and so what I entered into the text box is not saved (this happens in "Leave"). I have read previously not to use "Lost Focus" because it causes problems when you leave the form it triggers the "Lost Focus" on on the fields and just in general to use "Leave" rather than "Lost Focus". Is there a way to force my way through the "Leave"? I also don't know which field my cursor could be on (there are probably 20 text box or combo box fields on this form.
