VS 2005 - Zooming PictureBox On Mouse Hover
Feb 6, 2010
I've found an example of what I'm trying to do. The form will have 2 picture boxes. The first will be the original image. The second will have the zoomed image. Once I move my mouse over the first image, it must display a zoomed image in picturebox 2. I've attached the code that I found (written in C#) of what I'm trying to do. I've converted the code for me to VB. I want my first picturebox to be smaller than my second one. And the attached example shows that the first picturebox is bigger than the second one. I've never tried something like this, or drawing images etc. Just resize the 1st picturebox to be smaller that the second one, move with your mouse over the first one, and will see what I mean. I don't want to click on the image to have it zoomed or use the mouse wheel. Just want to hover over the image and display the zoomed version..

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
[Code].....

[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.

I have two questions in my mind!
1) What's the difference in mouse hover and mouse enter event in regard of vb.net?
2) Is embedding a resource in application more efficient or linking it on compile time?

I have a picturebox with zooming/pan capabilities. I am now starting with the zoom. I did that by:
getting the mousescroll event( up or down)
add height and width to the picturebox
get the pixel coordinates of mouse inside the image.
my problem is that, when i change the size of the picturebox, the pixel coordinates in the picture is not the same with the previous image without zoom. I need the coordinates to be the same even the picture is zoomed.

I managed to combine two .png images into one, and then display the result in a pictureBox image.However, the pictureBox seems to scale up my image! Makes it bigger!The pictureBox size is 96x128. The two images I have combined are 96x128. The pictureBox's SizeMode is set to "Normal"I have noticed that even though the pictureBox's image seems to be zoomed, it is cut to keep the 96x128 rect. But I don't want it to be zoomed...

I have a DGV that has a hidden column with some text in it. I would like to be able to mouse over any particular row and display the text from that column's field in a tooltip. I thought maybe I could do it in the DGV's MouseHover event, but I did not know how to detect which row the mouse was over. Once I do this, I did not see a .Text property for the tooltip, so how do I set the tooltip's content to be the text from the column field?

I have a program trying to use mousehover to pause the autoscroll. It is a widows form called:
lstOutput System.Windows.Forms.1 Below is how it is in my code.
Public Sub lstOutput_MouseHover(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstOutput.MouseHover
'Public EventMouseHover As EventHandler
lblPauseScroll.Text = "Output Paused" 'display output paused
'Highlight the DataGridView
Me.lstOutput.BackColor = Color.LightGray
[Code] .....
For some reason I have to click on the form to get it to pause the first time and then after that it does pause when I place the mouse over the form. It is that first time that it won't pause. The Public Subs I hand typed the codes in, is there some way that I should have added the mousehover to the form itself or are there other reasons that it won't work the first time?

I have a webbrowser control (in fact, a control inheriting from webbrowser), and added a tooltip control to the main form. Then, I filled the webbrowser tooltip text.But the tooltip never shows. (because the web browsers manage mouse hover with html?)I examined all the events exposed on the webbrowser control, and there is not one about mouse hover.so, the question is: How do I show the tooltip? Should investigate HTML, or there is a .NET control way?

I am using buttons on my vb.net forms. I want a way in which if I drag my mouse onto a particular button it would increase its size and if I click onto it, it can respond to the codes. May be like I want it too look like those Macintosh laptop icons, whereby if u put my mouse on it, it increases its size.

want my application to trigger audio files when the user clicks a word/sentence in a label, and show a tooltip on mouse hover. I use VB. I tried using TTS (SAPI 3.5), but can not know which language the user's operating system will have. Also, I was advise to use pre-recorded sound wav or mp3. I created the audio files, but am not able to link/connect/call.
