View 2 RepliesI 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";
i am looking for some sample code in order to upload and/or retrieve images stored in a database.even the web is full of samples, i was not able to find one without using blobs as i would like to save only the directory of an image when it comes to the place of storing. the reason behind is that i do want to have my database small for some reason and therefore only want to save links to my images inside.

I need to insert a Boolean value into an SQL Server datatable. I'm having a problem with what I'm trying. I don't see the option for a Boolean data type in SQL Server so I used Binary(1). Is this the right data type for storing Boolean in SQL Server?
The lines:
cmd.Parameters.Add(New SqlParameter("@Active", SqlDbType.Binary, 1))
cmd.Parameters("@Active").Value = False
generate the following error on the execute command:
InvalidCastException: Invalid cast from 'System.Boolean' to 'System.Byte[]'
Is there an example somewhere that covers how to store a boolean in an SQL Server table?
What is the best method in T-SQL 2008 for extending a table's records with the criteria of 'repeating' all fields but the Primary KEY e.g. Consecutive Date for the previous n Records.
So you have for example 7 records (Easy...2 Fields. Date and nvarchar) with th Date runing from Jan-01 to Jan-07
We want to extend the table by 21 records...so
Record 1,8,15,22 will look identical apart from the DateField.
Record 2,9,16,23 will look identical apart from the DateField. etc...etc..
I have tried a number of methods ...all coming up short....
I am building an app (ASP.NET 3.5 + SQL 2005) that allow users to schedule meetings and these meeting will show in the users to-do list.
One kind of meeting, when scheduled, should show into ALL users to-do list.
I have 3 tables:
#1 - Users -> UserID
#2 - Meetings -> MeetingID
#3 - Member_Meeting -> UserID+MeetingID
What I need is:
Based on the scheduled meeting, read all users from table #1 and add their info in the table # 3 with the MeetingID (which I can get from the UI, because it will happen when they create the meeting).
I have been browsing about it, but so far, I couldn't find a good source of info to start with.
Im trying to get the ID out of the record that i'm inserting using scope_identity. I've add the following line of code to the Insert statements in the sqldatasource - SET @insID = Scope_Identity() I've add the following line to the Insert parameter list
asp:Parameter
Name="insID"
Type="Int32"
Direction="Output"
I now want to insert a number records into the database using the following:
Dim insID As Object = e.Command.Parameters("@insID").Value ' gets out latest ID
Dim ordernumber As String = "CX" & insID.ToString & DateTime.Now.DayOfYear.ToString
sqlOrders.InsertParameters("orderNumber").DefaultValue = ordernumber
sqlOrders.InsertParameters("orderDate").DefaultValue = DateTime.Now
sqlOrders.InsertParameters("customerID").DefaultValue = userID
sqlOrders.InsertParameters("productID").DefaultValue = productID
sqlOrders.InsertParameters("totalPrice").DefaultValue = "0.00"
sqlOrders.InsertParameters("status").DefaultValue = "Paid"
I currently have this code in the SQLDataSource_Inserting sub but the first line only works once the record is inserted. How can i get the ID out as im inserting the parameters?
I have a table with casenum as primary number and Identity column turned on. I know that the casenum will only auto-generated after a record is written into a table.
The front end to this table is a FormView on an AJAX webform.
Table is linked to the webform via LinqDataSource.
Now, on the webform, how can I display nextval before the record is actually written into a table?
I have two tables cust and order_cust cust table have cust_id, name, addr, zip columns and order_cust have order_id and cust_id columns I take input from user for cust table i.e. name, addr, zip... the cust_id is an IDENTITY column so generates the value automatically Now I want to insert the last generated cust_id into order_cust (order_id is also an IDENTITY column)
How can I achieve that using stored procedure?
I have an editable grid where user can add/edit data. They also have the option to load previously entered data from last month. When the user then clicks save, i want to readd this newly modified data as a new record for this month. So basically I want to call the insertcommand, but it does not work. My 'save' method just 'updates' the records.

I have the logged-in user's Guid stored in a session variable. My understanding is that when the Guid is passed to the session variable it becomes a string. When I use the detailsview control I have to convert the session variable back to a guid and I've been doing it like this and it seems to work fine:
e.values("UserId") = session("LoggedInUserId")
Dim UserId as Guid = New Guid()
When I try to use the Insert() command after the following:
SqlDataSource3.InsertParameters("UserId").DefaultValue = Session("LoggedInUserId")
I get an "InvalidCastException" error with the comment "Conversion from type 'Guid' to type 'String' is not valid." I'm assuming the session variable needs to be converted to a type Guid since that's what I've had to do with the Detailsview control. I've tried a few different ways of converting the session variable back to a Guid so the insert command will work, but no matter which method of conversion I try I get errors such as "value of type system.guid cannot be converted to 'string'. I'm confused because I thought I was supposed to convert it from a string to a Guid. The "UserId" parameter is a non-primary key uniqueidentifier in the database.
I have a table right now with just customer_id and customer_name and I want to add an image field to upload their logo.
I've searched and found articles on how to create a table and to upload an image for a new row but how do I update or add a picture to an existing row.
So if I browse through my table and found a customer without a logo or an outdated logo, how do I replace and update their logo?
