Uploading Images To Sql Server
Aug 22, 2003Hope someone can help with this.
i am trying to upload images from an asp.net or vb.net front end to a sql server db.
I can upload the image fine if I first save the image to a file and then upload but my question is whether I can upload the image without first saving the image file. What i would like to do is to capture an image with a digital camera and without saving it first (an extra step for the user), upload it to a sql server db.
Is this even possible.
Thank you,
Biirir

Uploading Images/writing Info To DB
Feb 6, 2007In my continuing saga with writing my little real estate application, I've got the need to upload images to a folder within the website and then capture some image information in a db. I know there are many ways to do this, and have read lots of them. However most answers don't fit what I'd like to do, or they're too complicated for me. Anyway, thought I'd write it from scratch. So, I have 2 pieces of code, 1 that uploads the image to a folder, and another piece that captures information to a db. The first part works great. The image file successfully gets uploaded. Problem lies in the db insert code. It's not capturing and writing to the db. Here's my code, and thanks in advance for your help!

Uploading A File Into The Db
Feb 27, 2006I have yet to create a query string that works and it is beginning to drive me insane. I am trying to allow a user to upload a word document into my SQL 2000 database. However I always seem to get an error when it comes time to insert the file. The table has 5 fields memnumber, papertitle, and file type are all varchar. Length is an integer and actual_file is of type image. Here is my string
command = "INSERT INTO resumes (memnumber, papertitle, length, filetype, actual_file) VALUES ( '" & TextBox1.Text & "', '" & rightname & "', " & length & ", '" & type & "', " & filer & ")"
I can't tell you how many different versions of this string I have tried to run with none of them working, so the errors I have gotten have been varied. Most of them tell me either I can't use the & operator with file type image or that string or binary data would be truncated.

Dec 10, 2007Hello!!
i need to upload a csv file to sql server, i am trying to load using bcp or bulk load, but the files has null columns, so i guess, that's why the program is displaying error.
my table is as follows:
PK COLUMN TYPE SIZE NULLABLE
-----------------------------------------------
PK Object_id int 4 NO
SO varchar 4 NO

Segment_id varchar 3 NO

WWB_id varchar 3 YES
SC_id varchar 6 YES
PL_id varchar 9 YES
PS_id varchar 12 YES
PSS_id varchar 18 YES
Material_id varchar 18 YES
WWCC_id varchar 2 YES
THE OBJECT ID IS THE IDENTIFIER, SO IT SHOULD UPLOAD AUTOMATICALLY
MY FILE IS SOMETHING LIKE THIS:

Uploading Files To SQL Database
Mar 19, 2006I was following an example from the book "ASP.net unleashed" in Chapter 14, where it describes how to upload a file directly into the database.
I got it to insert the file into my database as described, and with changes created a master and detail form to select the file and display it.. (which I assume had worked).
Except, when attempting to access the file it gives two different errors. For a ppt file it gives:
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.
An invalid character was found in text content. Error processing resource 'http://localhost:3870/SeminarOrganiser/view_file...
and for a simple txt file:
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.
Invalid at the top level of the document. Error processing resource 'http://localhost:3870/SeminarOrganiser/view_file.aspx?...SELECT suggestEvent.suggestID, suggestEvent.uID, users.uFirstName, users.uLastName, users.uEmail, suggestEvent.suggestTitle,...From these two errors, I cannot really make sense of what has gone wrong or even why XML has even been mentioned. Looking around on the net has not allowed me any further progress.In any case, would anyone be able to explain to me what might have gone wrong?Alternatively, any links that may help would be greatly appreciated.Thank you very much in advance.

Apr 4, 2007Can somebody please tell me what I am doing wrong or need to do to resolve my issue. I having problems with one of the columns in an excel spreadsheet that I am trying to upload into the system. One of the columns contain values of both text and numbers such as 'ABC123', 'ABC124', '123456' etc. When I try uploading the sheet into SQL Server 2000 using DTS, the system removes all characters from the one column that I am having problems with. So entry 'ABC123' for example would be truncated to '123'. I tried formatting the column that I am having trouble with in excel to 'General' format as well as tried to transform the column to type varchar in SQL Server while using the DTS wizard but still had no luck. The problem is that SQL server thinks that the column is a float type column from the source and therefore truncates any characters.

SQL Server Express Uploading
Feb 24, 2008Hi All,
I have created my first database in SQL Server 2005 Express and would like to try putting it online.
I asked the web host to create an account. They gave me host name, database name, username and password.
The problem is that i dont know where i enter that information.
I cant find the answer in my books or online. The host said i needed MSSQL Enterprise manager.
Can i get this with the Express or do i need to pay for a different version of SQL Server? If Express has it, where do i find it please?
Any help much appreciated, as i'm completely lost!
Kind regards,
Justin

Connection String For Big Uploading Files
Oct 6, 2006I have a webpage where I want to upload pdf files to my database (arround 2 MB). Putting them inside the database is the choice based on audit definitions the client has.The problem is that for big file uploads, I get the "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding." error.I believe the solution is expanding the connection timeout time in the SQL connection. But I don't want to do that in web.config, as a small timeout is good for every page except this one.What I was thinking about was something like, on button command:- "create new connection string"- use that connection string to upload the file using the datatables and tableadapters- turn back to the default connection string. How do I explicitly tell the system to "use THIS connection string on the next task" ?Alternatively, another way of doing is also appreciated!

Apr 15, 2007HI, I have upladed my application to my remote server but then I get an error message. I am a beginner so any help would be appreciated and if possible explain the solution to me in a simpler format. Here is the error message: Server Error in '/' Application.

The source code that generated this unhandled exception can only be

the below steps, then request the URL:1. Add a "Debug=true" directive at the top of the file that generated the error. Example: <%@ Page Language="C#" Debug="true" %>or:2) Add the following section to the configuration file of your application:<configuration> <system.web> <compilation debug="true"/> </system.web></configuration>
Note that this second technique will cause all files within a given
application to be compiled in debug mode. The first technique will
cause only that particular file to be compiled in debug mode.Important:
Running applications in debug mode does incur a memory/performance
overhead. You should make sure that an application has debugging
disabled before deploying into production scenario.Thanks in advance.
Problem Of Uploading Asp.net Website On Web Server
Jul 16, 2007i have developed a website using asp.net, c# with SQL SERVER EXPRESS EDITION 2005. The database is being used both for retreival and updation purpose. the website is working accordingly when i m running it on my system, ie., data is getting retreived from the database and it is also getting updated on button click. But when i m uloading my site on the httpdocs folder of web server, connectivity with database is failing miserably, ie neither getting retreived from the database nor getting updated. The error message displayed by the web server is given underneath. i have used Grid view for displaying data from the database and Details view for updating the database.
i have used window authentication for connecting with the database.Please help me with finding out a solution for it. give me proper explanation and i need to do

Explain To Noob, Database Uploading
Dec 25, 2007hi,
From my ealier post I learned that a MDF file can be read and written to even if I did not attach the database in the SQL Sever Management Studio.
Is that behavior because of the connection string where is has
AttachDBFilename=|DataDirectory|DNN12_24_07.mdf ,
Is that what "attaches" the database? This runs on SQL Express2005.
Should I change the connection string to:
name="SiteSqlServer" connectionString="Server=(local);Database=ASPNET;uid=;pwd=;" providerName="System.Data.SqlClient" />
?
Is there a statment in the XML of web.config that defines |DataDirectory| of the original connection string that points to APP_DATA where the mdf file physically resides?
Thanks in advance?

Correct Way To Attach Database When Uploading.
Dec 26, 2007hello,
After I FTP a ASP.NET website to a webserver, APP_DATA directory and all, I then use the SQL publishing wizard to create a script on the local machine and run the script on the webserver/SQL server, it builds ok. But I get an error "another database with the same name". Duplicate of the database in APP_DATA directory that is already attached by the connection string. So this isn't correct.
Second attempt: I FTP an ASP.NET website up to a server. Then I open the SQL management studio and attach the database in the website's APP_DATA folder. (never running a .sql script)The database attaches. The name of the database is the complete path to the database in the APP_DATA directory by default. The website functions. But if I try to look at a table I get an errors. It gets to the point the database will not even expand. Then I start getting errors in the browser that NETWORK SERVICE can not open it's default database. So the website fails also. So this doesn't work either....
So I guess my question is, should I remapped the path of |DataDirectory| before I FTP it? To a path where the other common system databases reside, (I don't think that would be necessary.) Then FTP the website without the contents of the app folder(no database). Then use the script built with the SQL Publishing wizard to build the database, and attach the database in SQL Management Studio? ( I'm afraid of over playing and corrupting the server).
If I attach the database to manage it and the connection string attaches the database to run it, will I always get errors? What am I missing here?
Thanks jamesqua for your help so far, I understood the blog you sent me too. But how do I modify it so I can use SQL Management studio to manage the database?
