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 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.
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!
I am able to export an Excel file from Bytes and prompt the user to download/save when clicking an Export button (asp:button#btnExport). The download works fine when testing in VS2008 but when I deploy on the server (HTTPS), the browser returns the error"Unable to download showReport.aspx" from www.myserver.com Unable to to open this internet site. The requested site is either unavailable or cannot be found. Please try again later"Below is the code. Any suggestions please?PS:byteArray contains the Excel data I am sending to the client.
