Outputing A Text File Of 1s And 0s - Convert Binary To Ascii?
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!!
In .net streams are by default encoded in utf-8. so what i want to do is to simply read the text in a textbox in which i paste the russian characters and then convert them to ascii. but when i debug the code then in my resulting string ? appears. how i can convert the string into its ascii equivalent. my code is given below
string inputString = txtName.Text; ASCIIEncoding ascii = new ASCIIEncoding(); Encoding encoder = ASCIIEncoding.GetEncoding("us-ascii", new EncoderReplacementFallback(string.Empty), new DecoderExceptionFallback()); byte bAsciiString = encoder.GetBytes(inputString); string cleanString = ascii.GetString(bAsciiString);
Currently we are saving files (PDF, DOC) into the database as BLOB fields. I would like to be able to retrieve the raw text of the file to be able to manipulate it for hit-highlighting and other functions.Does anyone know of a simple way to either parse out the files and save the raw text on save, either via SQL or .net code. I have found that Adobe has a filtdump utility that will convert the PDF to text. Filtdump seems to be a command line tool, and i don't see a way to use a file stream. And what would the extractor be for Office documents and other file types?-or-Is there a way to pull out the raw text from the SQL Full text index, without using 3rd party filters?Note i am trying to build a .net & MSSql solution without having to use a third party tool such as Lucene
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.

I am saving user uploaded PDF files in SQL server using varbinary datatype. There is totally no problem in saving in binary and retrieving in PDF. But due to one specific requirement (which i cant change) i to need to fetch binary PDF and display in HTML or atleast get in string form.

I want to read and write excel file . it can do with oledb , there is a limitation maximunm characters < 255 solution is mono data type , now create table become second sheet (when open excel it is shown as hidden.)
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?
