I am using web services to retrieve one record from database. here in this record there is one image field.In web service, the record is converted to xml document and sent to client
when i send this record to client thru webservice , this photo is converted as byte[].
to check before giving to client, i checked my webservice. for that i took a new .aspx page and i retreived my record in to dataset and binded that to gridview. In gridview, I could see my image in byte[] format
I want to change this byte[] to previous image format in my asp.net page.
I am unable to change. I searched in google, I am unable to solve my problem.
Not sure if this is the correct section to ask this but this is regarding storing datatype problem.im trying to convert an image file retrieve from a folder and convert it to Byte so that i can save into database
In below function i retrieve and convert the image from a folder to byte
I'm retrieving a binary file from the database, a .pdf file that I would like to let the user open and view. From what I can tell, there are two steps to do this:
1. Convert binary file to byte array
2. Convert byte array to file content
Here's what I've got so far:

This isn't working and I'm having a heck of a time trying to find a solution. I'm getting a blue squiggly under c1.docData in the Dim bArray line.
i am store ms word resume to image(BLOB) data type in sql server 2005. now i want to display this resume in HTML page or in text area. and for that i use
I have a working application to save an image file to my sql database (Saves as "Original_Image" in the DB TBL_ImageGallery). I have a file limit on the upload of 1 MB. This also works great and the image is being saved beautifully. I found a bit of an issue. Being i am working on a network with 2 bonded T1 connections the streaming of images to my site, when tested internally, is effortless. I am not sure that this will be the same with a generic bandwidth. I want to store the original image size into the databse (already done) but also store a smaller sized (in bytes not actual size [Width, Height]) to my database in a "ThumbNail" column. This will allow the browser to only have to pass the "Thumbnail" sized image, obviously this needs to be much smaller than the original (ex: 1MB orignal I want to save as 12KB image in the thumbnail column), to the thumbnail img control in the user's interface.
I am not sure if this is possible or if there is a need of third party controls. I am interested in doing this as either a stored procedure or in the C# code on an event fire. There may be a better / other solution to this and if that is the case I am also interested
Is there a control that you can use? It can be done by fetching a binaryread from an aspx page but why there isn't a simple free image control that you can put in the page and feed it a byte array?
I am develping an application that integrates with an RFID kit. The problem is, the kit comes with an .cs class that accepts data stored in a byte array however, each information stored in the array respresents an int. I wanted to store String information in each array but, my research suggest that a String itself can be converted to a byte array and not a byte....here the code from the .cs class:
I have implemented the following functionality that connects to webservice and downloads a favicon from a given site and saves it to a byte[] which I store in our database. I now want to set it up so that it saves the icon to the disk. However I am getting a "Parameter is not valid" when I try and create the image from the byte[].My code is as follows..
The exception occurs on the middle line. This code works perfectly 9 times out of ten, but for some favicons, even thought the icon is a valid image (or at least it appears to be and it shows in the browser when point at it) I get this exception. Does anyone have any ideas? I am pulling my hair out here!

My texteditor will contain both text and image as seen in the string.
Now i want to store it in database and retrieve and display in a gridview.
I got a variable of type System.Drawing.Image and need to convert it to a variable of type byte so I can store the image in the database. Can someone show me how to do that in VB.NET code.
Here's a nice one for a Pro to bite into I have a web form that generates a set of reports including asp chart controls. Clicking on the black title loads the report section into the ajax enabled panel below it. Beautiful! Two Problems though: Sometimes, when the ajax is loading the next report section, all the other charts on the page flicker and sometimes even show a red x (the image disappears). They can then reappear again when another chart loads! 2nd Problem: If I use the html-to-pdf converter, I tell all the panels to bind to the data source (they are repeaters) on page load and show content. I Then convert the resulting datastream to PDF. All the other images on the page load, but the ones for the charts don't. I have looked at the generated code, and they are all linked fine to the correct address of the site and the chart generator url. A sample image of the working page is below:
