I am currently developing a web application that receives data from an on-site database. The database developers have developed some web-services that I am able to call and send/receive data to and from the the database.
When I want to display an image the method returns the image in BLOB format. My question is: what is the best way to convert BLOB to .jpg or .bmp so I can display the image correctly?
I have an application where a Word document is filled out and saved as a blob.

We are storing images in a DB2 database and would like to display them on the web page.
View 2 RepliesI am using C#. I am consuming a webservice. The webservice has a method, which has the return type as blob. The webservice serializes the data before sending as blob.I am able to access the webservice method, but I am not sure how to store the value, as the return type is a blob.I have tried this:
Service1.TestService serv = new Service1.TestService();
? = serv.Custom_methodname(true);
How to assign the output as it is a blob variable?

I am pulling word documents that have been stored in our db as blobs and presenting them to the user. As you can see below, I am writing to the http stream via BinaryWrite. This is causing the Microsoft Word application to open in a separate window. My goal was to open the word document inside of the browser instead. Preferably inside of an iframe within the browser. Is there a way to target an iframe by some analog of the method below?

View 3 RepliesCurrently 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
View 5 RepliesMy admin set innodb_buffer_pool_size=512M, innodb_log_file_size=128M, and innodb_log_buffer_size=1M although in mysql query show global variables its showing what the value is set. When i restart my system also its showing what we set the data.(It means we set log file buffer file size to max and its working fine.) but when i try to upload a file of 58 mb again its throwing error as The size of BLOB/TEXT data inserted in one transaction is greater than 10% of redo log size.
View 1 RepliesI have a string I need to convert back to a date. I can call .ToString("yyyyMMdd") and get the string i want. My question is how can I convert that back into a date? I'm trying something like the following with no luck.
DateTime d;
var formatInfo = new DateTimeFormatInfo {ShortDatePattern = "yyyyMMdd"};
if (DateTime.TryParse(details.DetectionTime.Date, formatInfo, DateTimeStyles.None, out d))
{
lit.Text = d.ToShortTimeString(); //would like 07/30/2010 as the text
}
I've never used DateTimeFormatInfo before if that isn't obvious. Can someone point me in the right direction. I know I could probably use substring and create a new DateTime(y, m, d) etc... I'm just wondering since c# interpreted .ToString() correctly, if it can't derive a date from the very same string it output.
