Mobiles :: Convert String To Byte (not Byte Array) And Store On RFID Tag?
May 8, 2010I 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;

Each t_b*.text respresents an int. Is there a way I can stored a String in a single byte block?

MVC - Use Byte Array As Source Of IMG Tag Through ViewData?
Dec 16, 2010I have a byte array of an image on the server side.
I have an img tag on my View page.
I'm wondering how to be able to use the byte array as the image source of the img tag.
I'm retrieving the byte array in my model, passing it back to my controller method and then I'd like to store it in ViewData somehow.
Then in the $(document).ready jQuery function of the View page somehow set that byte array as the source for my IMG tag.
Is this possible?

SQL Reporting :: Unhandled Exception Populating Byte Array
Dec 6, 2010This is actually a problem with a local report (RDLC) as opposed to an SQL report but this seemed to be the closest forum. I'm simply trying to have my page programatically open my report in PDF format. Ideally the preview wouldn't have to load at all but the way of doing it in pure code without loading a page with a ReportViewer control seems complicated to me, especially as the report has several subforms, all with different datasources (from an SQL server database).
So I'll settle for a page with a ReportViewer control which automatically opens the report in PDF when the page loads. I can't believe how much code is required for this! There are lots of tutorials on the Internet for this and I've tried several but without success. It seems to always fail at the same line, when adding values to the byte array.

View 3 RepliesConvert Datatable To Byte Array To Send As Email Attachment
May 13, 2014Every morning we send out an email with a text file attached. This is a manual process so I am automating it.I am using an internal mail web service. Its last two parameters are a byte array which is the file contents and a string which is the file name. I passed (...gbytes, "test.txt") and the only thing wrong with it is text.txt is XML. I want it to be text (csv is fine because there is actually four columns that come from a datatable).So I am assuming what's making it XML is this code:
Code:
System.IO.MemoryStream stream = new System.IO.MemoryStream();
System.Runtime.Serialization.IFormatter formatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
formatter.Serialize(stream, ds.Tables[0]);
gbytes = stream.GetBuffer();
I am trying to search the Internet for how to convert a datatable to a byte array, but I can't find how to have it be text instead of XML. Also, another parameter our WS takes is a flag to say if it's XML, and I am setting this to false.

C# - Creating And Save An Image From A Byte[] Causes Parameter Is Not Valid Exception?
Nov 18, 2010I 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!
