View 6 Repliesfile that requires images as part of technical explanations, so I have a form that opens that contains only a webbrowser control. I have designed my html document that views correctly in IE9 (images and all) and imported that as a resource. I then set that resource as the DocumentText of the webbrowser control. However, when the form opens the text is fine but no images - just placeholders! I am not trying to do anything fancy - the webbrowser control doesn't navigate away from the displayed doc at all and being distributed i don't really want to have to distribute the images seperately (hence using resource)

View 3 RepliesHowever, urldownloadfile will use proxy that internet explorer use. That part is what I want. The thing is the proxy used authentication. The proxy in internet explorer is authenticated. Using urldownloadfile will faile with error. It works without proxy.Anotehr is to copy the image to clipboard. That method is not reliable when user switch to another.
View 2 RepliesI am currently trying to get a WebBrowser object not to download flash and images. This is just to make a lightweight browser. I know this can be done within the IE settings, but i would prefer it on an application level.

WebBrowser1.Navigate(New Uri("http:google.co.uk"))

Is there a method like ebBrowser1.Document.Image(0).SaveImageToFile("C:Image.jpg") ?
I'm trying to make an application that downloads all the images from a photo album on the web. The user will navigate to the first image in the gallery and the program should download all images in full resolution automatically.
I have a working version now, but it is not satisfactory. Here is a simplified version of the code I use now for saving the images:
Private Sub startDownloading Handles WebBrowser1.DocumentCompleted
My.Computer.Network.DownloadFile(WebBrowser1.Document.Images(0).GetAttribute("src"), "C:image.jpg")
End Sub
This way, after the page with the image has fully loaded, it downloads the image using the Network.DownloadFile-method. So, it download the same file twice. But these files are big and websites are slow. Which makes the whole operation take about twice as long as it has to.
Is there a way to directly save the image-file that has already loaded in the WebBrowser-control, without having to download the image again?
Ok you know how our web browsers like Internet Explorer or FireFox has the option to "Save Page As". Is there a way to do this using the Web Browser Control? I wish to save the HTML + Images that are displayed in my Web Browser Within my application. Or say if I go to a website and they have a dynamic image that keeps Changing is there a way to save that image that is displayed on the Web Browser control?
View 6 Repliesi'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.

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.

The idea is to scan a folder of images and then let the user navigate back and forth through the images using a couple of buttons.The problem is, I can only get it to return a single image, and not the whole lot. It's looks to me as though the images are getting assigned to the same index in the array. [code]

View 3 RepliesThe app i am working on is for creating theme for the iPod touch... It has to deal with LOTS of images (100's potentially) There will be the set of default images, and then the user created replacement images. I started loading all the defaults into a resx file... thinking then I could just pull them out. now that I started setting the default, this sucks! lol the app will do this, on load it will set all the images (variables) to the resx images then when a theme is loaded, it will replace the default with the user image (if the user img exists) otherwise, the default stays. Then the "screen" is drawn to show the user. so, here is just the images to build the wallpaper, dock, and status bar...

I was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?

View 1 RepliesI have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree. I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:

Working the first time with a CheckedListBox.
Question: is it possible to disable an item of the box so you can't change the value of the checkbox.
Take the following fundamental code:
Private Sub btnStop_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStop.Click
btnStop.Enabled = False
'Lengthy code procedure
btnStop.Enabled = True
End Sub
I've just notice that when I click on a button, and try to disable it in order to avoid the user clicking on it several times during process (or disable the entire form for that matter), the application somehow records the subsequent clicks and processes them after the button has been re-enabled. But that's not the behavior that I want at all. I just want to disable any user interaction with the button (or the form perhaps) until processing of the Button_Click event is completed. How can I do this?
