Currently, I am using Itextsharp PDFStamper to Fill my PDF template. But my problem is, How do I return the completed File in Byte[] so I can open it using Response.BinaryWrite(Byte[]); in outputting the PDF file
View 5 RepliesI 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?

View 1 RepliesI've been reading quite a few tutorials on web services and xml files and one thing isn't quite clear to me. If I want to create an XML file on the fly the tutorials are pretty straight forward but, I want to grab an existing XML file from the web server and return the whole thing. Do I need to read the XML file and send each individual node or is there a way to send the file all at once? The tutorials imply that the whole file could be a node but I'm not clear on what that entails or if it would work. Also do you have a link to an example?

View 4 RepliesI 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.
