VS 2010 Add More Images To Imagelist?
Aug 26, 2011
I have a picture viewer with listbox,listview,picturebox. I used code snipets and modified them for about 3 weeks now. It works pretty good too i think. But when i add images as thumbnails to my imagelist from openfiledialog i can only add about 75 images any more and i will get a out of memory error. Or if I add say like 50 twice the second 50 added will have the right names but not the right image. My question is. Is there a way to load some images pause then load some more by code for about 250 images so that the loading could clean some memory? And or code where i could add aditional images to the imagelist? And i just cant stop trying to get this Picture viewer to work right.

I use this line of code to add images to a imagelist, and link it to listview, but it is very very slow. Up to 40 seconds to add 100 images.
Private Sub create()
Dim img As System.Drawing.Image
Dim imagepatha As String

How do I use a ObjectListView to show all the images in a image-list ? In the home-site of ObjectListView they have shown how to do this in C# (I am not that good with c# and delegates). But I can't get it to work in VB.net.

As you see the code given below is not very useful. Is it possible to shorten the code. Mousewheel back and forward give the same result (next image). Keydown cannot be configured.
Private Sub Images_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
count += 1
If count + 1 > ImageList1.Images.Count Then

I have about 100 PNG images stored in a Resource. Sometimes I need to have the same images in an ImageList, but I do not want to store the images twice in my application, so I add the images from the Resource to the ImageList during runtime when I need them.
Is there an easier way to do this than having 100 lines of code, like the small example below?
imgItems.Images.Add("A", My.Resources.A)
imgItems.Images.Add("B", My.Resources.B)
imgItems.Images.Add("C", My.Resources.C)
imgItems.Images.Add("D", My.Resources.D)

The code given below works fine. The only problem is mouse wheel/keyup cannot be used after the TOP image is displayed, it fills the keyboard buffer. Then I have to wait awhile to use wheel/keydown. Also the images after wheel/keydown goes beyond last image. It should stop at the last image like it stops at the first image. Code courtesy of Geek On Demand.

No Problem after the adding but restarting program, no thumbs in the items.

I'm building a virtual blackjack game and I'm having difficulty assigning values to the cards. I've set up picture boxes for the dealer's cards and the player's cards, and i've linked those picture boxes to an ImageList that contains all of the cards (+ the picture of the back of the card, since you only see one of the dealer's cards to start out with). When you hit the "Deal" button, I have the following code so far:
Private Sub btnDeal_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDeal.Click
Me.btnHit.Visible = True
Me.btnHit.Enabled = True
I have a section at the top that has labels saying: "Dealer's Showing ______", "You're Showing ________"how to assign values to the indexes/items of the imagelist? For example, items 0-3 have a value of "2", items 4-7 has a value of "3", and so forth...

I was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?

I'm creating a form which is basically an image in a picture box that I use the graphics object to do drawstring's and drawimage's upon.I keep track of where I'm drawing these things so that I can click on them later and do various things (launch external apps - whatever).Is using a picturebox and the graphics object the best way to approach this.

I have inherited a VB.NET project which was created in VS 2003 and is now in VS 2010. It works fine on one macine (32 bit). However, on my Win7 64 bit machine it simply won't build or run.

I need to overlap two images. When overlapped at the correct point, the overlapped portion of both images match exactly (or very closely).Now, I have tried to match the color of each pixel in the images, then move one image a bit and match them again until I get a high match rate, usually 95% or higher. The issue is, this is ridiculously slow. Also, I can't find a way to check the pixels if one I need to check a negative co-ordinate.
For y As Int32 = 0 To bmp2.Height Step 4
If y + StartPos.Y >= bmp1.Height Then Exit For
For x As Int32 = 0 To bmp2.Width Step 4
If x + StartPos.X >= bmp1.Width Then Exit For

I'm in the middle of making a program launcher. I've been able to make a version of it before, but now I want to add more options for viewing the shortcuts. The 2 main views I'm trying to get are: Icon only and Icon with the name.
Here is my original code for only the name:
VB.NET
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Start bottom right of screen
Dim working_area As Rectangle = _

I have switched over to a listview because I assume that's what i will need in order to show images. So I guess my first question will be how do I get only the icon from each file and then show it in the listview.

I've written some code to get an image file from a OpenFileDialog, and then offset the X position of the image by -50, and then display that offset image in a panel. But for some reason, it is displaying the image twice inside that panel. Could someone please tell me how to get it to only display the offset image in the panel? I'm sure it's something simple, but I'm wracking my brain with this one.

So I'm making a program that involves going online and entering a captcha, but the captcha doesn't show up. It just shows the outline of the image and then the name. How do I make it so the browser displays all images. I'd also like to know if there's a way to display the captcha in the main box.
