I have got one problem by uploading file. I created an aspx file in asp.net then I added a fileupload control and image control. I want to show preview image in image control before uploading. I created a following script.
[code]...
It is not work in every browser. How could I do that?
Is there a way by using ASPxUploadControl to have an image get uploaded automatically when you click the ok button after browsing and then get shown a preview of said image but only upload the image to the server officially after you click an ok button? I found [URL] which looks like it does the automatic upload but thats about all I've found so far.

I am interested in uploading an image to a file field using httpwebrequest or similar however I am stuck on a few things. Would it be a matter of add the file field and the image I would like to upload as the value? I'm not looking for code, I would like to learn how this can be accomplished.

I want to use the http:[url....API function to upload a picture onto ImageShack and then obtain the image_link. The only problem is, how do you place an image with its file name with the form-data along with the API key? This is what is stumping me in trying to implement the function.By the way, OpenDialog is already implemented to select the file to upload.
Update: I tried adapting the existing code to use the Unified API and it still does not work. If anyone knows what's wrong in the code, just make the modifications... Otherwise,
Imports System.Xml
Imports System.Xml.Serialization
Imports System.Xml.XPath[code]......
My idea is to add a entry to the windows context menu "Host File"
Then it will upload it to tinypic.
I assume it would have to be done using httpwebrequest?
I have always used the API for Vb.net from Decaptcher.com and have always sent the Captcha by sending an actual url to them as you see in the code below. Or maybe it uploaded the image anyway to them (I use the Webbrowser Control) [code] But with the current project that I am working on right now I am having to take a screen shot of the captcha image, then save it to my harddrive.I know that through your API Decaptcher allows us to upload the image from our harddrive but I just can't figure out how to use the code to do this. I have tried this but it doesn't work: [code]

I want to be able to kinda like have a timer that will get an image off my Hard Drive, and upload it online, so that all I'd have to do is download the image, even if it's been written over, I want to be able to broadcast an image from my hard drive, using only my IP Address.
127.0.0.1 is my IP Address.8888 is the port.Somthing like if you were to goto http://127.0.0.1:8888/update.html or Update.Jpg If YOU were to go to this address on your machine, you could see the image... Of coarse, it will probably be an image of which I was able to get from Printing my Screen image, and then saving it as like C:Test.Jpg, but the Timer would get my Desktop Image, or Print My Screen and Save it and Overwrite the Test.jpg image on the C Drive... Ya know what I'm talking about?

I want to resize the resolution of an image before uploading it to local storage. Right now it saves the image in its full resolution and I have to manually resize it using width="200" height="200" or a css tag in aspx. I want to reduce the file size of an image before storing it, hence by resizing the image resolution when the user uploads it via button. I've tried using System.Drawing before and setting the int imageHeight and int maxWidth to be resized but couldn't seem to get it to work.
My code so far is:
Protected Sub btn_SavePic_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btn_SavePic.Click
Dim newFileName As String
Dim SqlString As String

I'm attempting to grab an image from a webcam without having to connect a driver to a window. I'm predominately using code from a devx tutorial. On page two of the tutorial, it shows how to grab a frame using WM_CAP_EDIT_COPY. The only problem is, I don't want a preview window. I want to simply grab the image without having to associate a window handle to a PictureBox for previewing.

I have this as code to run the program
Process.Start(ListBox1.SelectedItem.ToString.Split(New String() {" "},
StringSplitOptions.None)(1))
Which used to work but then I added a "Preview image" function like this :
(ListBox1.SelectedItem.ToString.Split(New String() {" Image:"}, StringSplitOptions.None)(1))
I now discovered that the first code is useless, because it selects everything after " " to run, including the "Image:"
This is how a listbox item is stored:
Tomb Raider Level Editor - Original C:Program FilesTomb Raider - Level Editor omb4.exe Image:C:Program FilesTomb Raider - Level Editorload.bmp
As you can see it'll use this
C:Program FilesTomb Raider - Level Editor
omb4.exe Image:C:Program FilesTomb Raider - Level Editorload.bmp
to run
Is there any way I can make it choose the path from " " and when it finds "image:" it stops?

Problem : GetHtml is not a member of 'System.Web.UI.WebControls.FileUpload'
What can I do to fix this? Is it the good way to handle file uploads?
i have made a program that takes info from your registry and uploads it so I can fix it and you can download the new version of a key that makes things work faster.... when someone uploads a file, it works good, and i can look at the ftp's text file and see it, but every time someone ELSE uploads something, it overwrites the previous text file and makes another one, which deletes the first one. i would like so that when another person uploads something, it will just be on the second line then third, so on so forth.
