VS 2010 - Clearing List (Of Image) Storing Images In A List Of Image
Jun 10, 2011
I'm storing images in a List Of Image. When I want to clear/remove all the images it contains should I dispose & set each item to nothing before using .Clear? Or can you just call .Clear? I'm doing it like this for now...
' remove all images in list of image named "images".
For i As Integer = 0 to images.Count - 1
images(i).Dispose()
images(i) = Nothing
Next
images.Clear()
I have got two image folders namely a and b which consist of images of products. All images are save as there productid. how can can i find the images from a folder by passing there productid and save the images in a list.Dim AllImages As New List(Of String)
After saving it , how can i render those images one by one into string builder like
Dim imagecontainer As New StringBuilder For Each image In AllImages imagecontainer.Append("<img src="image" alt="" />") Next image
I am loading a series of JPG images into an image list then using that to fill a list view. My program is using ALOT of memory by doing this. What would be the easiest way to add the images but take up less memory/time?
i have a program with the ability to save view and scan images. i am currently working on making work area's. so i have two list box's. listbox one is for the image area name. listbox2 is to list the pages in selected image area (mouse click). i have created the form to show you and i will post a link below. i have started trying to do it but have got stuck. i use an input box to give the image area's names. but thats as far as i have got at the min.
i need to be able to make image area's and list/view the images in my picturebox. plus i would like to create a folder or how ever many the user makes behind the scene thats called whatever the image area is called and in that folder is the images the user has saved in that folder. sorry if this is hard to understand. i have asked on another forum but i didnt get what i wanted it to do.

i have gave you a link so you can see what my form looks like so you have a slight understanding on what i want it to do. its work in progress so sorry if it looks rubbish.
by the way i can save an image but it only saves it one certaint place and i cant save more thasn one as it replaces the image. and as for the scanned image thats the same.
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'm developing .NET app. and using some vb6 common controlsin design mode I can create image list and attach it to toolbar control but when I'm programatically adding toolbar buttons
I have a listview control. it has an imagelist attached to it with two images in it. I have entered items into my listview, and they are using the first image in my imagelist.... GREAT! Now, there is a variable I have that will tell me which index in the listview is currently active, noting to do with what I select that could be at another index it's just what's being processed by the program at the time in some task.
Create a function that will change the images of all my listview items by looping through them. If the index variable is set to 2, I want the 3rd item in my list view set to use the 2nd image in my imagelist. The rest of the items in my listview need to be set to the first image in the imagelist.
What I'm trying to accomplish is first of all, adding items in a list box, but while doing so, store data into that item so when the user clicks on it, the data will be brought up into the correct text boxes.
My idea on how this will all work out has to do with array lists. I'm thinking each time an item is added to the list box, an array list is generated containing all the data from the text boxes. The array list would be named as the text of the list box item.
So then when the user clicks on one of the items, it can find that array list easily because of the selected index, and then update the text boxes with the data.
Is the way I'm thinking of possible? If not, or if there is an easier what, what would that be?
I get some very generik trouble need to implement List View with Image in SubItem. All can be very fine ....But I need to use Virtual Mode. Whatever I search I haven't still found working solution's.

I'm trying to find a dropdown-style list for images I can use in a program of mine. It's fairly simple, just needs to display a few images in a grid with tooltips for each one, and I need to be able to get whichever one was last picked. For example,[URL] without the tab bar in it. Unfortunately my monetary budget is zero which means I can't purchase any controls?

I have manage, to allow user to browse through their files and insert an image path into a local database. The program will then retrieve the image from the image path and will be stored into ImageList. The Listview1 will then add the pictures of Imagelist into the ListView1.Items. Now my question, how can i retrieve back the path of the image when the users click on the selected image from the ListView?

I'm trying to make a game logger for MW2 so you can enter different stats and it will display those stats along with like your overall KDR for those matches and what not.Right now I'm just trying to do one match at a time meaning you enter your kills, assists, and deaths you hit the enter stats button then you hit the display stats button and a bunch of info shows up in the list box. Then you re enter different stats and it gives you the same stats but updates them for that match only. However, for some reason the list box isn't updating. It just keeps adding the kills, assists, and deaths together however the KDR does update.
vb Public Class Form1 Dim stats As Integer() = New Integer(2) {0, 0, 0} Dim kills As Integer Dim assists As Integer Dim deaths As Integer Dim KillDeath As Double Private Sub btnEnterStats_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEnterStats.Click kills = txtKills.Text '0 assists = txtAssists.Text '1 deaths =
