I have an image box full of images , im using a code to select a random image from the imagelist and display it in a picturebox.
My problem now is how can i check what image is in the picturebox and then have it do something else.
[code]...
I'm trying to update pictures boxes with images of controls stored in an imagelist owned by a control. The images stored in the control.imagelist do not showup in the picturebox. I'm working on simplifying the code to post, but for now could use help.If I store the image in a member variable owned bythe control it woks fine.Something to do with persistance of images in control owned imagelist? [code]

I have a Class that has an Image as property. A (possibly very high) number of instances of this class are added to a List(Of thisClass).
In a For Each loop, a new ListViewItem is created for every instance of the class in that List. The Image property of the class should now be the Image of that ListViewItem.
Now, a ListViewItem does not take an Image directly. Instead, I need to assign an ImageList to the SmallImageList property of the ListView, with a specified Key, and assign an ImageKey property to the ListViewItem.
Of course, I could simply add the Image in the Image property of the class to the ImageList, generate a random Key string, and assign that string to the ImageKey property of the created ListViewItem.
That does work, and gives me the correct image for every ListViewItem. However, it is not a very good solution I think, because, in total, there might not be more than like 5 different images! But there may be a LOT of ListViewItems, so there are a lot of duplicate images.
To prevent storing the same image 9183 times in the ImageList, I thought I could generate a Key to use based on the image. If the same image is then encountered later in the loop, I can see that this Key is already in the ImageList, and I don't need to add it a second time. Because they Key is then equal to the 'old' image, already in the imagelist, it will automatically be used for this Listviewitem.
I thought I could use the GetHashCode property of the Image, but apparently not...
Here is my
[Code]....
I thought this would work, but apparently the GetHashCode function returns a different number, even for identical images. I know the images are identical because I tried this by specifying the SAME image object as the Image property of the class, a few times. The GetHashCode is different everytime.
So is there any other property I can use, that is unique for identical images, but different for different images? Or am I going about this completely the wrong way? Or shouldn't I worry that there can be up to 10.000 duplicate images in the Imagelist?
I'm trying to get the image's name from a imagelist..[code]ofcourse that "name" doesn't exists, and I'm trying to find out what another correct way to get the name of that image.

Do i Need to use ImageList?
Does anyone know if it is possible to resize an imagelist/listview image without repopulating the image list? I am using scroll bar to change the image size from 25 point to 256 point. When I leave the scroll bar the imagelist repopulates from the files list. This can be very slow when working with high resolution pictures. I don't want to limit the image size to 2 sizes by using large and small imagelist.

I can not seem to figure out how to change the size of a photo being put into a picture box.I need the photos that are placed in the picture box to come in their original size....I have 4 different pictures in an ImageList and depending on what a Text box from a different form says, one of the photos will be displayed in a picturebox when the form is loaded. Right now all the images show up very blurry and in the predetermined size in the imagelist. Here is my code:[code...]
As you can see I figured out how to autosize the PictureBox (candypic) to the size of the image coming in....just cant get the image to come in as the right size.....
When I created the imagelist all the photos have a default size of 16, 16 when entered into the list.....I see in the imagelist properties how to adjust the image size but it groups them together as one.
I was searching MSDN for a function to grab an image from a website and add to my imagelist control. I could not find any thing on MSDN but did come across this.
image = ImageList.LoadImage(Filepath or URL of image)
http://social.msdn.microsoft.com/For...9-f63e40d2ccce
but there is no property in the imagelist control that does that.
am i missing something? if not what would you suggest best way to grab a url to use in my listview as an icon.
does anybody know how to put an image into a Byte array without specifying a format?
