Hi there
I'm using VS2005 (VB.net) and SQL 2005.
We've uploaded files from the web application to the SQL database.
The next thing I want to be able to do is to retrieve this uploaded file(s) from the database and attach it in the email when the user click on the Submit button on the web form.
How can this be done ?
Any help would be greatly appreciated.
TIA

Hi there,
I have inherited a databse and am building a new website to go wiht it.
There is a file upload page which will upload images to a directory. I need to insert into the database retrieve the id just added then upload the image renaming it in the format locID(QueryString)_ImageID(retrieved from database).jpg
The page has a file upload control and a button.
I am trying to write my code behind so that when the button is clicked it inserts location id into the images table retrieves Image id. Renames the file and uploads it to the images folder.
II think i need to call the routine from another routine for the button click but the signatures are different, where am i going wrong? or for that matter have i been pissing into the wind for the last 4 hours?
CODE BEHIND
Imports System.Data
Imports System.Data.SqlClientPartial Class admin_Add_Images

Greetings, I have just arrived back into the country (NZ) and back into ASP.NET.
I am having trouble with the following:An attempt to attach an auto-named database for file (file location).../Database.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
It has only begun since i decided i wanted to use IIS, I realise VWD comes with its own localhost, but since it is only temporary, i wanted a permanent shortcut on my desktop to link to my intranet page.
Anyone have any ideas why i am getting the above error? have searched many places on the internet and not getting any closer.

Hi, I have tried to implement file download option. I can download file which is stored in any folder. Code is... string filepath = Request.Params["file"].ToString(); string filename = Path.GetFileName(filepath); Response.Clear(); Response.ContentType = "image/gif"; Response.AddHeader("Content-Disposition", "attachment; filename=" + filename); Response.Flush(); Response.WriteFile(filepath);This code is working fine. But now I am facing a problem. Files (not the path) are stored in database table. User can download file from the database. How can I do this? The file may be a .txt, .doc, .xls, .jpg or .gif.

I have been trying to store binary file in a folder from the SQL Server.
Here is the code I am using to do this but, it is not working. It doesn't show any error only shows 1 row(s) affected. The folder remains empty after running this query.
I have already configured server using

Here's a table function that returns a table variable containing various file properties (creation date, size, etc.). The one limitation to remember is that it won't work with files on mapped drives; you have to use the full \<Server><Share><Folder1..Folder n><Filename> syntax. Still, it's a pretty useful thing to have around. :)

Hi,
my configuration file provides parameters that are used for an SQL query in my package. However, for these parameters it must be possible to pass NULL to the query.
This seems to be impossible in SSIS..? If the config file provides no value, the package uses a default value - and this default value can not be null.
Any suggestions?
Thanks a lot,

Hi,
Here's my situation. Every day I will be downloading extracts to a folder. The extracts are named:
20070529.Extract1.csv
20070528.Extract1.csv
20070527.Extract1.csv
20070529.Extract2.csv
20070528.Extract2.csv
20070527.Extract2.csv
So, on any given day, I will want to find the most recent versions of Extract1 and Extract2, for example:
20070529.Extract1.csv & 20070529.Extract2.csv
How would I go about doing this?
Thanks much
I need to retrieve data from a flat file and load it to a database table. I know how to do that. But what if I want to retrieve 3 fields from another table for each row read from the flat file source based on a date from each row in the flat file data source.

I would like to extract a file from a database. The file is stored in a BLOB format
Can I extract the BLOB file from the database using an SQL code/command or is there another way in which I can extract the file?
The file is stored as a BLOB but is actually a ZIP file (if that makes any difference)
What is the normal method of extracting a BLOB file?

Hi, Can anyone please help me solve this problem.
My functions works well with this stored procedure:
CREATE PROCEDURE proc_curCourseID@studentID int ASSELECT * FROM StudentCourse WHERE mark IS NULL AND studentID = @studentID AND archived IS NULLGO
But when I applied the same function to the following stored procedure
CREATE PROCEDURE proc_memberDetails@memberID int ASSELECT * FROM member WHERE id = @memberIDGO
I received this message
Exception Details: System.Data.SqlClient.SqlException: Procedure or function proc_memberDetails has too many arguments specified.Source Error:
Line 33: SqlDataAdapter sqlDA = new SqlDataAdapter();
Line 34: sqlDA.SelectCommand = sqlComm;
Line 35: sqlDA.Fill(dataSet);
Line 36:
Line 37: return dataSet;
The function I am using is returning a DataSet as below:
public DataSet ExecuteStoredProcSelect (string sqlProcedure, ArrayList paramName, ArrayList paramValue)
{
DataSet dataSet = new DataSet();
SqlConnection sqlConnect = new SqlConnection(GetDBConnectionString());
SqlCommand sqlComm = new SqlCommand (sqlProcedure, sqlConnect);
sqlComm.CommandType = CommandType.StoredProcedure;
for (int n=0; n<paramName.Count; n++)
{
sqlComm.Parameters.Add(paramName[n].ToString(),Convert.ToInt32(paramValue[n]));
}
SqlDataAdapter sqlDA = new SqlDataAdapter();
sqlDA.SelectCommand = sqlComm;
sqlDA.Fill(dataSet);
return dataSet;
}
If this is not the correct way, is there any other way to write a function to return a dataset as the result of the stored procedure?
Thanks.
I have a stored procedure that return either 1 or -1 : IF EXISTS( ) BEGIN return 1 ENDELSE BEGIN return -1 ENDAnd then I try to retrieve the returned value by doing this:int value = Convert.ToInt32(command.ExecuteScalar());But the value I get is always 0. Anyone see what is wrong?

View 1 Replies View RelatedHello! This is my scenario...
Development - Visual Studio 2005
Database - MS SQL 2005
I have written a stored procedure that has a output parameter whose type is NVARCHAR(MAX). Then I use C# to wrap this stored procedure in OLEDB way. That means the OleDbType for that parameter is VarWChar.
This works fine if the string size is less than 4000. If more than 4000, the remaining part will be chopped off. The situation gets worst if I replace VarWChar with LongVarWChar. There is no error nor warning at compiling time. But there is an exception at run time.
So... Does anyone here can help me out? Thanks in advance.
Hi all,
I am using SQLHelper to run a Stored Procedure.
The Stored Procedure returns 3 variables:
ie:
SELECT @Hits = COUNT(DISTINCT StatID) FROM Stats
...etc...
The SP is currently called as below:
SqlParameter[] sqlParams = new SqlParameter[]
{
new SqlParameter("@FromDate", Request["FromDate"]),
new SqlParameter("@ToDate", Request["ToDate"]),
};
My question is this: How do I retrieve these variables?
I know I need to declare a new SqlParameter and change it's Direction to Output but I am unsure of the exact syntax required to do this.
Thanks in advance,
