VS 2010 ListView / Resize Images / Image Types / Click Action?
Jul 20, 2011
Imports System.IO
Public Class Form3
Const IMAGE_DIRECTORY As String = "C:images"
Dim files As String() = Directory.GetFiles(IMAGE_DIRECTORY)
Dim max_length, i As Integer
Dim s, fname As String
[Code]...
I simply want to have a list of all graphics saved in specified folder displayed as miniatures - this suppose to be a sort of an image browser - it does not have to be done using ListView, so I'm open to any suggestions.

I need to click an image in a webbrowser from a Windows Form in VS 2010.I can click ordinary links using code such as this one:
Private Sub Button14_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button14.Click
Dim lnk As HtmlElement
For Each lnk In Form2.WebBrowser1.Document.Links
If lnk.InnerText = "the_text_of_the_link" Then
[code]....
When it comes to the second variation of the code I often get the following error message (exception):NullReferenceException was unhandled Object reference not set to an instance of an object.
Basically - how do I tell it to click on it only if there are two separate and unique strings of html code in a html tag?

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 a form where i load an image to a picturebox. I open a dialog to prompt the user to grab a file and once that is done i pull the image into a picturebox. Now i want to resize all incoming images but.... because of how it affects my ability to draw lines in the picturebox i am restricted to leaving the picturebox size mode set to normal. So i set out to write a resizing function.
The issue i am having is that eventhough i pass the function an image. I get the Height and with from the image object and it appears that i should be tripping some of my IF/Then statements ... neither Scl or Scl2 ever gets set which in turn keeps nw_height and nw_width from setting themselves properly.
All 4 of those variables stay 0 at all times and im not sure why.

I have 52 listview items in my listview1 and I have a picturebox basically I want it where I can click on a single item in the listview and display an image from a url in the picturebox. I basically have it right now that when you click on any item in the listview it just shows the same image in the picturebox no matter which item it is. I need to figure out how to do it separately for each item.

The object is to load an image into a picturebox, then save a new copy of the image in a different location, but with the height and width of the image box not the original file's height and width but I can't figure it out. I've got the loading and saving working no problem but getting it to adopt the new size is stumping me, it just keeps saving with the original file's size properties

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'd like to make a simple VB utility to resize images using vb.net. I am having trouble figuring out what vb class to use to actually manipulate the images. The Image class and the Bitmap class don't work.

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.

If i type this in:
CODE:
I get an error: Error 1 Operator '=' is not defined for types 'System.Drawing.Image' and 'System.Drawing.Bitmap'.
I have also used 'is' instead of '=' but that doesn't work either.

I'm using a web cam that takes 320 X 240 pictures. This sort of gives the picture a "landscape" look to them, and I need to re-size the pictures to a 169 X 225 "portrait" picture. Its for a badge program. Anyway, when I re-size the pictures, they get all scrunched up because of the difference in aspect ratio. Is there a way to re-size the image and the aspect ratio at the same time? Would this be considered cropping or resizing? I'm a little confused on where to begin. I mainly use VB, but if someone has a good example in C#, ill take the time to convert it.

I'm using VS 2010 and MySQL 5.5. I've got a data grid view displaying the results of queries entered by the user, shown below. It works; the trouble is that if there's an image in the results, you'll only see a cell-sized very long thin strip of it.
So I want to a) resize any images to a reasonable thumbnail height (say, 100 pixels, naturally maintaining aspect ratio) when displaying them, and b) resize the row to fit them.[code]...

I have a Form1 where i can add usercontrols during runtime. I draw their appereance in the OnPaint event using the GDI+ engine. The greate part is that i want to be able to resize these images during runtime wich goes pretty well now cause i draw points in percentage of the control. Unfortunetly it is very difficult to draw nice images/drawings ect with the GDI+ engine. Is there any other way in doing this?

I have been able to associate a listview control with an imageview control to display images. There are a couple of things, I would like to do.
1> How do I display the image in the second column? 2> How do I increase the size of the image getting displayed? My images are all 48 x 48 (pixels), but they keep shrinking.

I'm trying to make a visual map editor, and figured that a DataGridView would be the best way to go. I would like to make it so that you can click one of many buttons to set which new image the grid cell will be set to when you click it. I've set up pretty much everything except that I can't figure out how to set the background image of the cell that I clicked.
