I have a database which stores .png images as the sql "image" type. I have some code which retrieves these images as a byte[], and sends them to the page via the FileContentResult object in .Net. Performance is key in this application, and the images have to be retrieved and displayed as quickly as possible. My question is, can this operation be performed quicker by passing a byte stream from the database to the browser, and not at anytime storing the whole byte array in memory. If this is possible and worthwhile doing, how do I do it?
I will keep checkbox for each one to select. Suppose a user selected the four files and clicked the button,which I kept under. Then I instantiate clasees for each type of file to convert into pdf, which I wrote already and converted them into pdf and return them. My problem is the clases is able to read the data form URL and convert them into pdf. But I don't know how to return the streams and merge them.
My company has just purchased a .net version of Cete Pdf Merger (great product btw). We use both .Net & asp code and will likely use java in the future as well.
The scenario is that one technology (asp, java, .net) would have a list of raw data such as an array of field names & values. This data would be posted to the web service that would then open a given pdf, match pdf form fields to the field names array, grab the corresponding value, populate it on the pdf, and then stream the pdf back to the user to download.
I'd like to write and read TCP Streams directly without any modifications by ASP or IIS. Is this possible?
Edit: Goal is to provide communication between a program and a server. Data exchange between them is less then 25 bytes per connection (in default case). So Headers will cause more traffic then the real data. I need to use ASP.Net because the owner of the server will not let me execute my programs.
I am about to get my sites hosted with a local host company. They are offering me their lowest cost MSSQL server, which is the web edition. So my question is what is the difference between that and 2008 express edition? Can express edition be used for a full fledge in production website? And does Web implies that I will be interacting with it via the web correct. Lastly, if the web version is not chosen what is the typical protocol for uploading and maintaining a site when you have a dedicated server. Do you normally have to go to the data center or is there like a web portal that can be used. I will be asking the guys at the company these questions as well, but I want to make sure I get another opinion on the issue.
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 asked plesk the following question:I've been through the documentation and scoured various forums, but I can't find a defintive guide to uploading an mssql db (contained in a app_data folder) to the server and conecting it via the Plesk control panel. I've created a db and user via the panel but how do I get the actual db to the server and get it to work?"and they replied:"For database restoration please upload your database backup file ( i.e. .bak ) under your hosting space and update us the exact path where you place this file + your database login details ( i.e. database name , database user name and password ). So we restore this database for you. "
I often hear the term database driven web app and just wanted to make sure using that description is the most accurate when describing an asp.net web app that relies on an SQL Database for all of its dynamic information.
I have created a C# registration page that includes a secret question and answer. The secret questions are in a dropdown list. When the form is submitted, all field information gets written to my mssql database successfully but the value selected in the dropdown ListItem gets NULL inserted instead of the question.
This may not the best place for this question, but I'm going to give it a shot. I have a large (3GB) file that contains maybe 100 fields, CSV. ALL FIELDS are surrounded by double quotes, a standard CSV file. So, it looks like this:
"12345678", "SMITH", "JOHN", "GARLAND, TEXAS", "75043","","","","37" (and so on)
I need to import this into SQL server but have been unable to find any simple way of doing so using the BULK INSERT. I could obviously do it with some coding [a lot, given the number of fields] but one would think a product like MSSQL would have this most basic of functionality built in.
my question is that i actually want to make a table in a database and update delete the recordsin that table The thing is that i dont want to make the database table in the sql server but i want to make it in the visual web developer (the editor i am using) can any body gimme any idea abt how i can do this orany link regarding to this
I was wondering what you guys thinks is the most efficient way to select data from a msSQL database.. I tend to use a sqldatareader, but is this really the best way? - It is particularly impractical if one also must take into account, that the table may be "Null"?:

I have a page, there is a pre-created checkboxlist, for certain people it should be possible to add new checkboxes to the list.How should they do that? Here is what I have in mind.
Next to the checkboxlist there is a button (Add new items), when clicked a popup should be shown, there the name for a column (in a pre-created table MSSQL) can be entered (this column is only a text column), column is created and when clicked ok, the checkbox is added to the list (checkbox binded to the just created column).

I am new to asp programming and have inherited an old website that was connected to an SQL 2000 server. The SQL 2000 server is being retired and replaced with a SQL 2008 server. We moved the DB to the new 2008 server with no problems. However the web site does not function (Database Connection error). I believe the problem is with the old asp code being written for mySQL vice SQL. It may have worked on SQL 2000 but it does not seem to work on SQL 2008.. The code is below:
<% function write_it(mystr) if not isnull(mystr) then
On the internet we bought/hired a CRM product. When we enter a new project this datarecord (on their MSSQL DB) is transferd to our local MSSQL DB.
Internally we got a seperate application that uses the project information.
So after an insert project on the CRM side (on the internet) the data is transferred to our DB. When i check the internal application I see the project. All nice and sweet.
BUT when I alter (UPDATE) a project in the CRM internet application this data is pushed to our DB and i see the data in the table. But it doesnt show up in the internal webapplication. When i restart the website in IIS it still doesnt. Only when i restart the entire IIS the data is updated in my internal application.

We need to send out about 10.000 letters each month. They will be sent via postal services so I have to print them out with a new label/address on each letter. The envelope does have a window so the letter will be printed with the address.
All addresses will be found in a MSSQL database. I know how to make a SQL connection. I really need some input on how I would start doing this. The letter will be a twosided letter with the address in the upper right corner. How can I make a connection so that it loops trough the database for address and adds one by one. It should also add a new letter/page for each address found in the database.
