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 have a simple photo viewer application where i want the user to click a "load sequence" button and then i want something like a folderbroswerdialog to appear then the user can pick a folder with images in it then the images get loaded into the picturebox and the user can click a "forward" button to go to the next image in the sequence and a "backward" button to go to the previous image in the sequence, it's kinda like windows 7 photo viewer.
View 17 RepliesThe idea is to scan a folder of images and then let the user navigate back and forth through the images using a couple of buttons.The problem is, I can only get it to return a single image, and not the whole lot. It's looks to me as though the images are getting assigned to the same index in the array. [code]
View 2 RepliesMy app has scrolling images in the background and a picturebox on top. The image in the picturebox has transparent parts. How can It so that the transparent parts show whatever is belo the picture box, not the form background? I have tried taking screenshots and positioning them as background but this just freezes the app.
Dim ScreenSize As Size = New Size(154, 83)
Dim screenGrab As New Bitmap(154, 83)
Dim blank As New Bitmap(100, 300)

can we use images in the resource folder as background images by setting the background image during run-time by coding?

View 1 RepliesI 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:
Dim picLight(2) As
Boolean

I want to do is blend two images together with a varying amount of transparency using a scroll bar/trackbar. In software I can do it by drawing an image into a picture box and blending another image on top with a varying amount of transparency but it is using gdi which of course is very slow. I would have thought that it should be very easy with fairly basic modern graphics cards but I am so bogged down with examples of how to draw fancy rotating rectangles etc with direct x that I can't see through it all. Should I look at directdraw, direct3d, opengl?

View 2 Replieshi there, i have a problem with my picture box which has the facility to zoom and pan with scroll bars, when i zoom in on the image then move the scroll bar down and leave it there and then click my 100% zoom button, the image is only just showing at the bottom of the screen and it is movable so you have to drag it into position when you shouldnt need to because it was fixed.
View 11 RepliesI have application, where is a big image, displayed in picture box, but only a part of image is on the screen (I set display mode "zoom", so it's center). But now, I need to fluently scroll this image using mouse, so when I click on picture box, and move mouse, the visible part of image should be changing.
View 2 RepliesI have a picture box in my form and now I want to add an event so that if the mouse is scrolled up the scale of the picture box gets larger and when the user scrolls down the size off the picture box gets smaller. This way I want to make a zoom in and out effect.So now i have the following code in the mouse wheel event of the Picture box:

But somehow this whole mouse wheel event isn't fired.
I have a picturebox inside a panel, the picturebox is long, and the panel is set to allow scrollbars, which it adds. I can scroll the picture at design and runtime, but how do you scroll it programmatically?
Starting with the picture box with the top set to 0, and then doing this... (using any non-zero value as the lY value)
Dim newLocation As New System.Drawing.Point(0, -lY)
[Code]....
So how do i get the value to change (e.g. to scroll the picturebox!)
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?

View 11 RepliesI've dynamically added 20 pictureboxes to a panel and would like to see the panel scroll when I use the mouse wheel. To implement this I have tried to set the autoscroll to true on the panel control. Here is the code.
For i As Integer = 1 To 20:
Dim b As New PictureBox()
b.Image = Nothing
[Code]....
It works for "button" control, but not for the "picturebox" or "label" controls?
How can I implementthe scrolling affect using 'mousewheel'?

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)
bmp.MakeTransparent(clr)

I also tried to see if changing the image from background to foreground would help...no such luck.

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'm using VB.NET 2005 and mySQL server 5.0. Can i ask how do i retrieve the image from database and display images onto picturebox? mySQL column name is pictures then the data type is varchar. and how should i write on the database? eg. abc.jpg?
