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
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.
How can I save image in db as byte array and show the saved image as slide show in my web page with C# asp.net 3.5
View 1 RepliesIs 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?
View 15 Repliesi got an image display in my system, note that it is not an uploaded file, it is display in <asp:Image> form
My question is, how do i use that image and convert it to a byte data so that i can save into database?
I get the data of the stored image on database as byte[] array;then I convert it to System.Drawing.Image like the code shown below;
public System.Drawing.Image CreateImage(byte[] bytes)
{
System.IO.MemoryStream memoryStream = new System.IO.MemoryStream(bytes);

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:
byte BlockNo = 0;
byte[] BlockData = new byte[16];
byte ReturnCode = 0;
[code]....
Each t_b*.text respresents an int. Is there a way I can stored a String in a single byte block?
i am not getting the output. I can able to display the image using generic handler.What i need is to display without using generic handler.
View 1 RepliesI 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..
stream.Write(imageByteArray, 0, imageByteArray.Length);
Image i = Image.FromStream(stream); // EXCEPTION HAPPENS HERE.
i.Save(@"C: mp" + filename + ".ico");
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!
if (Session["image"] != null)
{
ImageButton1.ImageUrl = "~/IMAGE/pic.jpg?" + DateTime.Now.Ticks.ToString();
}
The session key image is from another aspx page
{
string strPhoto = Request.Form["imageData"]; //Get the image from flash file
byte[] photo = Convert.FromBase64String(strPhoto);
FileStream fs = new FileStream(Server.MapPath("~/IMAGE/pic.jpg"), FileMode.OpenOrCreate,
[Code]....
The issue is
Operand type clash: nvarchar is incompatible with image.
ArrayList lstEndPoints
0 element "0x01"
1 element "0x82"
byte b = (byte)(lstEndPoints[0]); //Error cannot convert

i am failing to get the Base64 string and show it as an image in the output pdf file.
I have a signautre canvas that saves the output directly into the sql database.
