Imagelist - Function To Grab A Image From Url?
Apr 10, 2011
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 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 have got an imagelist with many images, many of which have a critical name which can be changed in the desinger, however, since Im NOT using this imagelist in another control (e.g. tabcontrol) I am not able to use imagekey. Therefore, how am I able to get the name of an image in my imagelist?

Imagelist1.image.add("DSCF00082.jpg")
I tried using the above code to add an image to an IMAGELIST but it is to no success.
I want to know if there is a way to add an image to an image list via code as opposed to using the collection.

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.

does anybody know how to put an image into a Byte array without specifying a format? I have a Listview with images downloaded from the internet and I want to save them all together to the hard drive as a single file, by using a structure. In order to do this I need to put the Imagelist images into a byte array. When the application starts I reload the images into the Imagelist again.

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?

What I have done is named a bunch of picture boxes "Q," "W," "E," etc. (the whole alphabet) and named picture that correspond to these picture boxes ("Q.png," "W.png," and so on) and added them to my resources.
For example, the following code would give the picture box named "Q" it's corresponding image "Q.png":
vb
Q.BackgroundImage = My.Resources.Q
Of course, it's kind of a pain in the backside to copy and paste this code and change all the Q's to W's and so on, so I was hoping to create a function to do the job for me:
vb
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
'So that I can run the letter as a string through the function,
[Code].....
Hopefully I've provided enough detail so that it is obvious what I'm trying to do.
Obviously, the code I tried above (the second block) doesn't work - it gives a syntax error. I need to change/write to make this function functional.

Does anybody else think that it is just plain STUPID that you can add images to the imagelist at design time but you can't add a key?? What kind of brainless moron designed that?Now, everytime I change (add, delete, etc.) an image in the imagelist, I have to modify my code that accesses any image after the changed image(s). What REALLY boggles my mind is that it is still this way several years later. If I could at least access the image's name from code, then I could get by. But, NOOOOOO! That also would make too much sense

Why these two different ways of assigning a background image work differently?
When I load the image into an ImageList, and then reference the ImagaList.Images collection to set the background Image for a control, it looks llike crap. The smooth blend I had set up is stratified.
When I load the image directly from the Resource, it looks great.
I assume this has something to do with the bit depth of the image once it is stored in the Image list collection? Or some other conversion issue. However, I can't find a way to adjust these properties on the image list (They are read only).
Here is the way that looks like crap:
