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.

View 2 RepliesI 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.

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.

View 6 RepliesI need something like ObjectListView and LGPL, BSD or some license that allow its uses in commercial applicatioTo use ObjectListView commercially, companies normally buy a license. A license to use ObjectListView commercially is 100 euros for small companies or 500 euros for medium sized companies. This license gives the company permission to use ObjectListView in any and all of its closed source applications. The license fee covers the current and all future versions -- there are no upgrade fees
View 1 RepliesI am trying to programmatically add in a ModelFilter to my ObjectListView that will look at two (or more) columns and filters on each separately. Currently, I think that ObjectListView only supports one filter, but I may be missing something in the code/documentation.

I have added a freshly compiled ObjectListView.DLL to my VB.NET project and I've added a ObjectListView control to my form. But, thus far I have been unable to do anything with it except make it throw exception errors of various kinds. I know I'm not supposed to use it using the same syntax that ListView uses, but the documentation for this control is as well developed as MSDN's for ListView--which is to say vague to nonexistent. I can't use ListView because it gives me no control over row height and cell padding. Both need to be minimal, but with the defaults used by ListView, you could move in and and make a living between the entries. Too much space. I need things compact because the application I'm developing needs all the real estate it can get for other purposes.
View 3 RepliesI am writing a program that shows random images in three picture boxes. When I open the program the initial images are in the picture boxes. When I click stop, the program is supposed to select a random image out of five. in each picture box. However, when I click start the images go away and when I click stop, no images appear. There is also a message that is supposed to come up on the screen, which it does. I just can't get the images to show. I am using Visual Basic 2005.
My code is below:
Public
Class videoBonanzaForm
Private images() = {image1, image2, image3, image4, image5}
Private image1 As Image = Image.FromFile("sevenpounds.gif")
Private image2 As Image = Image.FromFile("push.gif")

I am stuck in showing images of a requested webpage using Httpwebrequest/httpwebresponse (VB.net) classes. I can make calls to get the target webpage and display the result but it doens't show the images.
What I come to know through googling, is one way to add <base href="target webpage url"> tag in <head> section of resultant strings received through httpwebresponse and the display the modified result. For this purpose someone suggested me using Html Agility Pack.

I am using a DataGrid, in VB, I have a check box. If it is checked I turn image.visible to true. This is done within the ItemDataBound method.

View 1 RepliesI am trying to setup a treeview control to display all drives and folders on the PC. So far I can display all drives and folders but the images will not show except rarely. I am using an imagelist with 4 images (index 0-3). The code below is used to load the drives in the treeview control. I have tried using every type of image possible from bmp to png and nothing. I have tried the Appllication.EnableVisualStyles() which I now know isn't needed in vs 2008. I am also having problems with a picturebox in another form that shows nothing but a shadow of the image. I suspect this may be a setting somewhere maybe in vs 2008 but am not able to find one.

i'm making an app which uses a webbrowser control to show some offline (not cache) html pages like a slide show. let's say pages in a folder on the desktop etc when it came to testing the whole thing, i figured out that the images in the html are not visible on the webbrowser control. instead there is a space where the image should be, corresponding the actual image dimensions.and when i right click on this empty space where images should be, and click on properties, i see the image size given as -1 byte (minus 1 byte) and there is no image type.
however given any online url's to the same webbrowser control or opening the same html pages with the real internet explorer i got no problem and see the images.i've been googling for almost 10 hours for a solution without success, so any hints are welcome. used vb 2008, .net framework 3.5, ie 7.
Which of the VB controls is best suited to show images in a strip like fashion from an Image Array?I have an Image Array.

View 1 RepliesDoes 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
