Web Forms :: How To Convert Pdf File Into Binary Data Using File Streams

Nov 28, 2010

My files are stored on a data repository in different formats like .doc,.docx,.pdf,.jpeg,.jpg,.tiff. I want to get those files in binary format(i.e byte[]) so that I can able to see that file to the user using a radbinary image control.I am able to get .jpeg and .jpg files and I can show those to users.But while I am trying to show .doc,.docx,.pdf files I am getting "Not valid parameter" exception.How can I solve this problem? My doubt is that pdf,doc,docx files are having no of pages. So while converting this total pages in to binary data I am getting error. So How can I show first page of .doc,.docx,.pdf files using radbinary image control.Here is my code.RadBinary Image controlis a telerik control,it only deals with binary data.

Feb 13, 2010

I am outputing a text file of 1s and 0s. I want to shrink the file so I'm going to convert it to ascii. Its going to be used on a clientside web application so I can convert it back to binary with some scripting later on.

So, I want to convert the string of binary to a string of ascii serverside in vb.net. I have spent much time searching the web for a vb.net solution, and, what a mess!! everyone thinks they know how to do it, but none of the solutions have worked so far!!

File Upload String Or Binary Data Would Be Truncated

May 17, 2010

I have a website that uploads different file types, creates thumbs from the files and saves the file and thumbs to their respective folders. every so often it throws an exception string or binary data would be truncated, Ive never encountered this locally. I have a problem pinning down the circumstances that it happens, I thought it was documents with spaces in the name but that works sometimes as well. This is really bugging me and I need to fix this. The db table fields are long enough, trust me . Has anyone else ever encountered this issue?

Mobiles :: Read Binary File Into String

Mar 27, 2011

i am working on the mobile application, and i want to read binary file .. its just contains the string.. e.g "hi Wel come". I have opened that file using filestream and try to read that file using binaryReader.. but it didn't read that file correctly. if i use

Response.BinaryWrite(buffer);
Response.flush();
Response.close();
Response.end();

it shows me the correct result as i want ..i.e it shows the "hi wel come" on browser. like this i want to store that content of file into string
