MouseHover delay with PictureBox

1 New Member
I have recently designed a Winform Image drag & drop utility. The approach I took was to have a Panel control serve as a destination for multiple file drop. Once the user dragged & dropped the desired files I do a check to ensure that I only process the image files (".jpg", ".png", etc), while any other files are ignored by the program. For every image file being dropped I programmaticall y create a PictureBox control, do proper resizing of an image in question, load it into the PictureBox, and finally position the PictureBox with appropriate offset within the Panel to ensure it is nicely aligned with the rest of the PictureBox controls.

Now onto my question.... for each PictureBox control I implement a MouseHover event by means of which I am changing the color and thickness of the border for the PictureBox pointed by the mouse. I don't know why but I can't help but notice that there's a considerable delay between the time the mouse is over a given PictureBox control and the time I actually see the new border appear around it.

Has anyone here gone through similar experiences and found a workaround to eliminate this delay? I know the PictureBox is redrawn every time I mouse over it and I believe it's using GDI+ graphics object in the OnPaint() method to redraw the changes, which may account for the slowness. But is there a way of implementing the border change functionality for a PictureBox control to avoid this delay ?

MouseHover by design, doesn't fire until the mouse has been stationary for some time.(Quote microsoft)
If you want immediate results look for MouseEnter and MouseLeave events.
(If need be you can also check out MouseMove, but the other two should be fine)

Receiving a single mouseHover is simple, just move the mouse over my control and wait. However, following this mouse hover event, if I move the mouse around within the control and once again wait, nothing happens. I have to move out of the control's perimeters and come back and wait to trigger a hover event. So, my question is : how do I tell the control that I'd like to receive a MouseHover event everytime mouse stops moving over the...

I am working on the component and would like to change a display when the user stops moving the mouse inside the control. I used the MouseHover and MouseMove to change the status, but the MouseHover does not fire again unless the mouse is moved outside the control. Is there a something I am missing or Is there a better way to do this. Thanks for any help

I want to introduce a one-second delay into the MouseHover event of a label. In other words, I want the user to have to hover over a label for one second before the label's MouseHover event triggers a response from the application. Here's what I've got so far: -- Add a timer control and a bolean DoAction flag to the form. -- Set DoAction flag to false and the timer for a one second interval.

I have a label on a Windows form. I have the following code which doesn't work when I mouse over the label. Any idea why? If I change MouseHover to MouseEnter it works. So, what good is MouseHover? Private Sub Label1_MouseHover(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.MouseHover Label1.Text = "Yo mama" End Sub

Hi All, Using VB.Net with SQL Server.

Hi all, I have a program which will routinely update the image of a picturebox and resize the picturebox to keep the aspect ratio of the image in tact. The problem I am having is that after about 10 or so changes of the image there is a really long delay in updating the image. The size properties will update but the image itself stays the same. I have tried forcing it to revalidate (even though changing the size of the picturebox does this)...

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

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
