filestream

How could I know the physical location (so I can see it in Windows Explorer) path of a FILESTREAM data that I've just inserted into DB? There is one option for this: method PhysicalPathName(). If you are on SQL Server 2012 or upper now, this code will work for you: SELECT stream.PhysicalPathName() AS 'Path' FROM Media OPTION (QUERYTRACEON 5556) For SQL Server 2008/2008 R2 you will need to enable trace flag 5556 for the whole instance: DBCC TRACEON (5556, -1) GO or for the particular connection in which you are calling PhysicalPathName() method: DBCC TRACEON (5556, -1) GO I know this is an

I wanted to ask if it is possible to redirect writes to a specific file, to a memory stream in my application so I can immediately read it. If it is possible please explain how to do so. Thanks. Make sure your application works with Stream , and then you can use the MemoryStream concrete implementation to accomplish streaming without a file. What you need is a stream which writes to a file as well as to another stream which you are watching - a stream splitter, commonly known in the Unix world as tee . For .NET you can use this implementation of a stream splitter. Pass it a FileStream (so that

I'm trying to send a file in chunks to an HttpHandler but when I receive the request in the HttpContext, the inputStream is empty. So a: while sending I'm not sure if my HttpWebRequest is valid and b: while receiving I'm not sure how to retrieve the stream in the HttpContext Any help greatly appreciated! This how I make my request from client code: private void Post(byte[] bytes) { HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("http://localhost:2977/Upload"); req.Method = "POST"; req.ContentType = "application/x-www-form-urlencoded"; req.SendChunked = true; req.Timeout = 400000;

I have some image-files stored into one file (some kind of archive). That file looks like this: Well, it's separated into two segments - header and data-segment. Header (green) contains various info, such as album name, location, date/time, description, number of photos in the album, etc. Data segment (blue & orange) has simple structure and it contains N x JPEG photo. I can extract that "imagedata" segment into new TMemoryStream object and now I want to show it using TImage. I can use SaveAsFile method of TMemoryStream, set some temporary file-name, load that file from TImage, and later,

I've been using File.ReadAllText to grab some csv, but every time I forget to close the file in Excel, the application throws an exception because it can't get access to the file. (Seems crazy to me, I mean the READ in ReadAllText seems pretty clear) I know that there is File.Open with all the bells and whistles, but is there an 'intermediate' method which doesn't involve messing around with buffers and char arrays? Yes, I'm lazy, so vote me down, just give me the answer first :) Noldorin I think you just want the following: using (var fileStream = new FileStream("foo.bar", FileMode.Open,

I have created multiple csv files using datatable and want to zip all those file into one single zip file. Which is i'm doing all at dynamically. I tried following code List<string> filestream = GenerateCSVfiles(dataSets); //Generate CSV files public List<string> GenerateCSVfiles(List<DataSet> dataSets) { List<string> filestream = new List<string>(); StringBuilder result = null; foreach (DataSet dataSet in dataSets) { result = new StringBuilder(); System.Data.DataTable dataTable = dataSet.Tables[0]; foreach (DataColumn colm in dataTable.Columns) { result.Append(colm.ColumnName+","); } result

I'm trying to load binary file using fstream in the following way: #include <iostream> #include <fstream> #include <iterator> #include <vector> using namespace std; int main() { basic_fstream<uint32_t> file( "somefile.dat", ios::in|ios::binary ); vector<uint32_t> buffer; buffer.assign( istream_iterator<uint32_t, uint32_t>( file ), istream_iterator<uint32_t, uint32_t>() ); cout << buffer.size() << endl; return 0; } But it doesn't work. In Ubuntu it crashed with std::bad_cast exception. In MSVC++ 2008 it just prints 0. I know that I could use file.read to load file, but I want to use iterator
