View 1 RepliesDataSource Controls :: Saving And Retrieving Images From Sql Server 2005
Jan 5, 2010I am facing a problem with retrieving an image and showing it on asp.net grid. I migrated MS Access database to sql server. Image are visible in Crystal report when fetched from the same database (migrated sql server database). But same images are not visible in ASP.Net grid view or simple asp.net image control. Following is my code
SqlConnection oConn =
new
SqlConnection(ConfigurationManager.ConnectionStrings["csr"].ToString());
oConn.Open();
SqlCommand oraCmd = oConn.CreateCommand();
oraCmd.CommandText = "select top 1 photo from [test] where photo is not null";
SqlDataReader dr =
null;
dr = oraCmd .ExecuteReader ();
if(dr.Read ())
if (dr["photo"] !=
null)
{
Response.ContentType = "image/gif";
Response.BinaryWrite((byte[])dr["photo"]);
}
This function is getting called from another page . "hlopen" is hyper link in the grid. hlopen.NavigateUrl = "GetPhoto.aspx?id=1";

DataSource Controls :: Data Retrieving And Checking Queries?
Jul 28, 2010I'm currently working on a FOREX Live Trading project that I'm implementing.
I already have a database that stores the CURRENCY PAIR, BUY/SELL, PRICE AND QTY.
But I have a huge problem.
Scenario that is:
A person BUYS EUR/USD at a PRICE of 1.29900 @ quantity 100,000. (This will be recorded in the database table)
Then he BUYS EUR/USD at a PRICE of 1.29950 @ quantity 100,000. (This will then be recorded in the database also)
Then he decides to SELL his EUR/USD at a PRICE of 1.31000 @ quantity 200,000 all out. (How can I check from the database if he previously had make a transaction of BUY/SELL, so that I can do my necessary calculations for the P/L Statement)

DataSource Controls :: Retrieving And Displaying Only Current User's Data?
Jan 21, 2010Having trouble with a web page and connecting to SQL DB. Basically I have a form view table connected up to a SQLDataSourceControl and what I want displayed in the form is only data that has been assigned to the user that is logged on now. I have a "ViewAll" page, which lists EVERY field, regardless of who it is assigned to, but the "MyTasks" page should only retrieve the data of the current user.
I have two tables in my DB, the "Users" table, with user data (including an ID number) - this is used again in the "Tasks" table as a foreign key called "AssignTo". Therefore if user Joe Bloggs with ID number 5 logs on, whenever someone assigns a task to him, they will select number 5 in the "Task" table, as this relates to his User ID.

View 3 RepliesDataSource Controls :: Retrieving SQL Filestream Data With Visual Studio SQLDataSource?
Jun 4, 2010Is there anything special you have to do to retrieve Filestream data using a SqlDataSource? I'm using VB and have this as my sqldatasource:

DataSource Controls :: Retrieving Binary Files From SQL And Download It?
Mar 17, 2010My apps required me to store upload files into SQL binary fields. And then allow users to retrieve the files and either chose an apps to view them or save on disk. These files can be in diff formats, not just one type.
I have been reading about using the Response.ContentType method and Response.AddHeader method. The issue is the users can upload anykind of documents, ie: MS words, Xcel, JPEG,TIFF.... So at the time of downloading, I have no way of knowing that type it is to put in the Response.ContentType.
Can't I just stream it to the browser, let the download dialog box handle the type selection? as in when you download a file, the dialog box would ask if you want to select an app to open the file or save it on disk. How would I do so ?
