I am having trouble to make a form that displays the picture of the student which all his info is in a datagrid. I used the following
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' TODO: This line of code loads data into the 'BdSyngentaDataSet.Training' table. You can move, or remove it, as needed

It worked. But, when i click on the next student and go back to the previous, the picture is not there. When I stop the debugging and start again the picture is there but it stops displaying again after going back and forward.

store and retrieve image in a SQL Server database with vb.net.:Well, the application in vb.net seems to have a database which can accessed by the LAN computers so the SQL Server 2005 database allows remote computers to share its database once the other computer application requests database from the server.So, every other computer has to store and retrieve images in SQL Server 2005. For example, comp1 has to store images taken into the server and retrieve it like tableadapter.
I am using bindings and tableadapters to store the details in database and retrieving information from db. Please if you have code or anything which is working for me, please post it here... how to store image and retrieve it SQL Server through vb.net provided there's LAN computers who are also sharing the SQL Server database.
i found in internet, many examples are regarding insert only one image. but now i want it to have multiple uploaded images that we can delete and view it first before we save it on database. how to store the images uploaded?

I have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree. I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:

In VB6 I could embed a panel or picturebox containing controls or images within an outer panel or picturebox. If I moved the outer control then the embedded panel would move with the outer panel and stay in the same relative position, which is what I require. This doesn't seem to happen in VB.NET, the internal panel stays fixed in its location, even if I have pasted this panel within the outer container. Is there are trick to this or do I have to code to get the internal panel to move with the outer one? How does an internal container remain embedded within an outer one?

I have made a screensaver in VB.NET. I am running into some roadblocks in the code though. The idea first was to have a ball bounce across my screens. It then evolved into spawning new balls that bounce across the screen. I then added collision detection so they would bounce off each other. Here is the problem that came up:
When said balls overlap each other, you can easily distinguish the edges of the picturebox that holds the images. I have made the background of the picturebox transparent, made the bitmap with a magenta background and made magenta transparent (for the image), but I can still see the picturebox edges when they overlap. It seems the transparency is not only making the background transparent, but giving it X-RAY vision to display not the visible area behind it, but the root background color of the form. here is a sample of the code which makes the transparencies.
Private Sub frmscr_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim bmp As Bitmap = My.Resources._smiley_face_image
Dim clr As Color = Color.FromArgb(255, 0, 128)

I have a pictureBox on my form along with two buttons (Back and Forward) but I can not find a viable method of doing what I wish to do: Scrolling through images in a folder like the default Windows Picture Viewer does with Arrow Keys.Is there an efficient way to do this?
I'm using Visual Basic .NET with Visual Studio 2010, if that matters.
I'm trying to accomplish is having a 20x20 pixel image show up multiple times as determined by the grid selected. To keep things simple, what I'm trying to do is create a 9x9 grid of a image onto a form. I'm assuming that a picture box is the way to go, but don't know how to make that happen or if it's even possible.
So it would go something like this:
2D array already assigned:
Sub ShowGrid()
For rw As Short = 0 To 8
[Code].....
But instead of using a text box with values, I want to show a grid of a small image file, like cup.png which is 20x20 pixels or whatever, so what would show up on the form in this case would be a 9x9 grid of the image file over and over to create a grid.
Then the next step I hope to accomplish is to have that 20x20 square picture hold the grid(x,y) value for a mouse click. So if the image at grid(3,5) is clicked, it will give me that value, 3-5.
I would like to have a series of images displayed sequentially in a picturebox (every 10th of a second). I captured the images (image0, image1, etc) and placed them in a temp folder every 10th of a second.
