Use MouseEnter Event With An Array Of PictureBoxes?
Dec 2, 2011
I have text for ToolStripStatusLabel1.Text in a file which is read into an array.
There is an array of PictureBoxes, which are used for the MouseEnter event.
I am trying to display different text in the status when the mouse is over a certain image. In the code below, the Array.IndexOf() generates "Index was outside the bounds of the array.". The commented line will change the text when I change the Index but, it changes it for all images.

I need a 'low-coded' way on how to use 'MouseEnter' and 'MouseLeave' event (in Visual Basic 2010) on a Web Browser, but strictly as OBJECT. So I don't need any of those HTML stuff... I just want one small Web Browser to dissapear when I take my mouse off him...

I'm trying to make an image fade in/out when the user hovers over the button. The fadein works when I enter the button but not when I leave it. How can I make this work?
Animation Code:
Private Sub GreenBg_animation()
Dim myduration As Duration = New Duration(TimeSpan.FromMilliseconds(250))
Dim da As DoubleAnimation = New DoubleAnimation
da.Duration = myduration
Dim sb As Storyboard = New Storyboard
[code] .....
Button code:
Private Sub btn_2_MouseEnter(sender As Object, e As System.Windows.Input.MouseEventArgs) Handles btn_2.MouseEnter
GreenBg_animation()
End Sub

I'm trying to make my application become the active window if it currently isn't as soon as the mouse enters the main form of the application (so there is no need to click the title bar of form itself to make the window the currently active one if it's not).
It only sorta/kinda work .... I have to enter the form with the mouse 3-4-5-6-maybe 7 times ... then the window finally becomes the active one.
I know the MouseEnter event is firing each time the mouse enters the app, but the main window isn't becoming active most of the time.
Private Sub frmMain_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.MouseEnter
rtbStatus.AppendText("Just got a frmMain.MouseEnter event" & vbCrLf)
[Code]....

I want to change the background color of an element when the mouseEnter event fires. How to make the color of the background darker?? I thought I can use an opacity mask, but it's a gradient, but I need it to be solid. Also it has to be in visual basic code, not in xaml.

I have an array of picture boxes with images. I want the status bar to change when the mouse enters the image. I am stuck on displaying the correct text when the mouse is over a pictureBox.
hr1StatusText is an array of text read from a text file. Everything works but I can't figure how to iterate through the text for the status bar.
The code below works displaying the text for all PB's as long as the index is changed. What I am looking for is to display hr1StatusText(0) for PB(0), hr1StatusText(1) for PB(1), etc.
Public Sub Tile_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.MouseEnter
Dim TileMouse As PictureBox = DirectCast(sender, PictureBox)
ToolStripStatusLabel1.Text = hr1StatusText(0)
End Sub

When i use my UserControl in a project my Mouse Enter & Leave events aren't firing, i assume i fix this with a raiseevents in my usercontrol. However when i try to do this it says something about "cannot raise base event from derived class".

I have 5 pictureboxes on my form and would like to but then in a collection or array to use them in a loop. I would like to use the FOR EACH loop... but how..
Th pictureboxes are placed in a Table. Here is my code so far.
Dim TableHeaders As String() = {"PERIOD", "GRADE", "SUBJECTS", "POSSIBLE ATTENDANCE", "ACTUAL ATTENDANCE", "% ATTENDANCE", "DISTICTIONS", "NUMBER ENROLLED", "STUDENTS WRITTEN", "STUD PASSED", "% RETAINING", "% PASSED", "TERM MARK", "NAT AVERAGE"}
[Code]...
It says that PictureBox is a type and can not be used as an expression, so how do i do it?

I have this code. credits to jmchiney. My goal is when I press a certain key, the picturebox corresponding to that key should be moved to a certain location. Exactly like in the text twist game.
I have a code running and doing what I want but It is only applicable for single letter. For example the word alabama. all letters without duplicates are placed properly but for letter a, only one letter a is being accepted and moved. that goes for all letters.
Here is the
Dim pb As New PictureBox
Select Case (e.KeyChar)
Case CChar(letterPicbox1.Tag)
[Code].....
Another one. when a certain letter is already placed to the location I set and once I press again the same letter, the location changes. What I want is when I already gave pictureboxA a location and then I press "a" which correspond to pictureboxA again it should be stationary and check if there are other letter "a" in my pictureboxes and move the next detected letter "a" to the next position. Like i said. just like text twist game.

I have a VB2005 project that displays 16 pictureboxes in a 4x4 grid which display CD album covers. In VB6 I could set up a control array i.e. picCD(0) to picCD(15), which made drawing the CD covers a snap. How do I accomplish this in VB2005?
It seems extremely cumbersome to have code like: If Len(path(0)) < 1 Then
If Not IsNothing(PictureBox1.Image) Then
PictureBox1.Image.Dispose()
PictureBox1.Image = Nothing
End If

I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?
Heres the tutorial with my new code encased in asterisks ...

I am having two issues with making my Maze Game in VB.NET. I want the levels to be difficult to solve so I am making some *sliding* (NOT MOVING) Panels to interrupt the players.These are my problems:
1. I want the Panel to slide (Sliding Up and then Down, then Up and Down, then Up...) forever, but it doesn't. It will only slide the times I have written the code.
2. I want the MouseEnter event to work when the mouse touches the Panel during the Panel is sliding.
3. Is it right to use a Timer?
Here are some details and the codes which I have used:
I have first made an Integer = 6 for the speed of sliding.The timer is not enabled and started. It will be started and enabled when Button1 is clicked.
Timer's interval: 100
Panel's name: Panel1
Timer's name: Timer1
When the user clicks Button1, Timer1 starts, which will slide Panel1. (My code is for moving the panel. I need to slide the panel. IT'S WRONG![code].....

In my application I have 4 panels. Each of which have a "mini-app" such as a calculator, sticky notes, etc.My GUI could use improvement so I had an idea of making the Border of a panel glow where if your mouse enters or focuses on the panel or its children the border glows.I have not yet worked with glowing type elements and am not sure how I would do this. I just want the border to glow like the Start button at the bottom left corner of your screen in Windows 7. The start button glows on mouseover and focus. To my knowledge I believe they just use two images, but how did they use the animation for "glow effect"? [code]

setting the form opacity programatically in the MouseEnter and MouseLeave events.The problem isn't with the actual events, the problem is that the events occur in places where I don't want it to happen.So in my project, I have a form with 3 user controls in it. The user controls are docked in the form so no actual space from the form is available to the user.
I have the methods:
Form1_MouseEnter(~) Handles Form1.MouseEnter, UserControl1.MouseEnter, UserControl2.MouseEnter, UserControl3.MouseEnter
Form1_MouseLeave(~) Handles Form1.MouseLeave, UserControl1.MouseLeave, UserControl2.MouseLeave, UserControl3.MouseLeave
when you enter the form, the form opacity is set to 1. And when left, the form opacity is set to 0.7 .However, what happens right now is obviously that when the user changes the mouse position from one user control to another, the form opacity flickers (turns to 0.7 and back to 1 really fast).

I am trying to search the 4 columns of my array by using this click event. The column is determined by a radio button as you can see. I changed my code from last time and now it works, but only for the first column. If i try to search out a string in the second or third columns I get an error based on the line highlighted in blue HTML accutally shows and it is green. the error says Index was outside bounds of array
Like i said It works fine for all values in the first column, accually the second (Numbered 1). If i enter a value in the partsnumBox and it is found in the the 2nd 3rd and 4th columns I want the value in the first column (0) of the same row.

I've found out how to create my arrays with code, instead of the old way (easier way) I'm used to from VB 6. At first I created 10 picture boxes on the left and 10 pictures boxes on the right. Then I coded an array of labels to display the words. However, the text would not show up on top of the picture boxes, even after I sent the picture boxes 'to the back'. So then I created an array of picture boxes as my cards with an array of labels to display the spelling words. This works quite well. I have also used a loop to randomize the first spelling card chosen to display on each side of the screen, so that the 'cards' are in different places. (Its not completely randomized this way, because they will still be in order, but at least I get all 10 words and no duplicates. I doubt my son will figure out that they are still in order anyway. He will just know the words aren't in the same place on each side of the screen.)

I create a dynamic number of PictureBox controls. I keep them inside a List. What I want now is to make them clickable: same event handler for all (opening of the image source file) with a parameter. The question is: how can I do it in practice? How I set the handler Sub for every picbox?
