Retrieve Images From SQL Db: Code Problem.

Aug 1, 2006

Hi,
I want to get an image from a sql server database and display it with an asp:image control. I use C# in MS Visual Studio .Net 2005 and Sql server 2005.
All I've done is:



// and Page Display_image.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
try
{


SqlConnection Con = new SqlConnection(
"server=localhost;" +
"database=;" +
"uid=;" +
"password=;");

System.String SqlCmd = "SELECT img_data FROM Image WHERE business_id = 2";

System.Data.SqlClient.SqlCommand SqlCmdObj = new System.Data.SqlClient.SqlCommand(SqlCmd, Con);

Con.Open();

System.Data.SqlClient.SqlDataReader SqlReader = SqlCmdObj.ExecuteReader(CommandBehavior.CloseConnection);

SqlReader.Read();

System.Web.HttpContext.Current.Response.ContentType = "image/jpeg";

// I write this:
System.Web.HttpContext.Current.Response.BinaryWrite((byte[])SqlReader["img_data"]);

// Or this:
//System.Drawing.Image _image = System.Drawing.Image.FromStream(new System.IO.MemoryStream((byte[])SqlReader["img_data"]));

//System.Drawing.Image _newimage = _image.GetThumbnailImage(100, 100, null, new System.IntPtr());

//_newimage.Save(System.Web.HttpContext.Current.Response.OutputStream, System.Drawing.Imaging.ImageFormat.Jpeg);


Con.Close();

}
catch (System.Exception Ex)
{

System.Web.HttpContext.Current.Trace.Write(Ex.Message.ToString());
}
}

Both work the same way. I mean the image is displayed well but when I view code of the web page I see this:

....
GIF89aåo÷óå݉97)HS¢Å’xL£0¬B´ç¬D(áâK‹†ô²–I€8`È®û l1ãÂ?#KžL(ˆ*X±â€°Î"«M豆Ÿ
....

TOO MUCH characters before the html tag. And any code of the master page used for this page does not work as well!

Can anyone help me with this? I've tried for 2 days but I still fail.

Thanks.

How To: Store And Retrieve Images In A Database As A Byte Array.

Feb 28, 2008

I€™ve inherited a project from one of the guys on our team who will be out sick for a while. He developed two for marshaling data between System.Drawing.Image and System.Byte(). He€™s storing the byte array data in a database image field.

I€™ve retrieved the byte array data from his database image fields and have successfully converted them to images using his ConvertByteArrayToImage method below. I have also converted and image to a byte array with his ConvertImageToByteArray method below and succfully stored the data in a database image field. However, when I retrieve the byte array data that I stored in the database the last line in his ConvertByteArrayToImage method throws an exception (Parameter is not valid). I€™ve not been able to find a working copy of his code that€™s storing the byte array data. Does anyone see anything I€™m overlooking?

Imports System.Drawing
Imports System.IO

Dim lImage As Image

Backing Up / Restoring 20 GB Database With Images Stored As Binary Code

Oct 29, 2015

I am trying to backup and restore a 20GB SQL database from a SQL Server 2012 to another SQL Server 2014, but I have come across the following issues:

1) The developers [against best practice] have stored multiple images in fields within the database as binary code.

This therefore exceeds the 65532 character limit in some fields, so even though the images do show [based upon the data saved within this field], I cannot find the data in the field beyond this 65532 limit, within SQL Server.

How can I export / locate this data after the 65532 character limit?

2) When I have attempted to restore the database I am getting this error message:

Restore of database 'zapkam' failed. (Microsoft.SqlServer.Management.RelationalEngineTa sks)

Additional information:

System.Data.SqlClient.SqlError: RESTORE detected an error on page (1:1592996) in database "zapkam" as read from the backup set. (Microsoft.SqlServer.SmoExtended)

I have managed to restore two other smaller databases using the same technique, but am wondering if it's an issue with the database itself.

3) I have uploaded this database to the new server using FileZilla FTP Client, but it has cut out, painfully at 80% + 90% on a couple of occasions.

Is there a better solution for uploading these big files that I could possibly use? For example, uploading table by table or similar...

Cannot Retrieve Code Page Info...

Nov 20, 2006

Hello again!

I got a problem using an OLE-DB Source in my data flow task. It is an Informix-Server using the newest OLE DB-Driver provided by IBM. However, when I set up the OLE DB-Source with connection manager and SQl-Query, I get the following warning message:

Warning at {2B334CA3-A792-4BC2-93AA-12FADCF1E696} [OLE DB Source [45]]: Cannot retrieve the column code page info from the OLE DB provider.  If the component supports the "DefaultCodePage" property, the code page from that property will be used.  Change the value of the property if the current string code page values are incorrect.  If the component does not support the property, the code page from the component's locale ID will be used.


Later when I try to execute the package, the destination adapter gets errors like

Error 3 Validation error. Data Flow Task: OLE DB Destination [2985]: Columns "antrag" and "Antrag" cannot convert between unicode and non-unicode string data types. Informix_OLEDB.dtsx 0 0 
 

I guess that SQL Server cannot get the data types from the Source.

Has anyone an idea? Thanks in advance!

Unable To Retrieve The @@Error Code In Stored Procedure

Aug 25, 2006

Hi All,

In my application on click of Delete button, actually I am not deleting the record. I am just updating the flag. But before updating the record I just want to know the dependency of the record ie. if the record I am deleting(internally updating) exists any where in the dependent tables, it should warn the user with message that it is available in the child table, so it can not be deleted. I want to check the dependency dynamically. For that I have written the following procedure. But it is updating in both cases.

CREATE proc SProc_DeleteRecord
@TableName varchar(50),
@DeleteCondition nVarchar(200)
As
Begin
Begin Transaction
Declare @DelString nvarchar(4000)
set @DelString = 'Delete from ' + @TableName + ' where ' + @DeleteCondition
execute sp_executeSql @DelString
RollBack Transaction --because i donot want to delete the record in any case
If @@Error <> 0
Begin
select '1'
End
Else
Begin
Declare @SQLString nvarchar(4000)
set @SQLString = 'Update ' + @TableName + ' set DeletedFlag=1 where ' + @DeleteCondition
execute sp_executeSql @SQLString
select '0'
End

End

Thanks & Regards

Way To Retrieve Actual Size Of Ntext Column In Native Code?

Aug 3, 2007

Howdy folks! (I feel im creating too many topics...but all my questions are unrelated :-/)

Dev environment: SSCE, Native c++ OLE code, Win CE 5

I have a routine that calculates the size of a set of columns in order to create a byte buffer for retrieving data from an IRowset and inserting it into a custom class. This method works great for all data types except ntext. When I look at the column information from an ntext field, the DBCOLUMNINFO::ulColumnSize member holds 536,870,911 (the max length of an ntext type). Obviously I dont want to allocate 1GB of memory for each ntext column. Is there anyway (natively) to determine the actual number of characters in a field?

How To Create Apps That Write Code To Retrieve Data With Foreign Keys?

Apr 6, 2007

Hi GuysOff late, I've grown with programming that requires more than a number of tables that has foreign keys with other tables' primary keys. It takes a really cumbersome coding to retrieve the code from another table with the other table having foreign keys. My question is, how do we program VS 2005 such that it does all the retrieval of the data from the database instead of us writing the code all by ourself?Is it really good database technique to bend the normalcy rules and have one to two columns having redundant data?Can anyone tell me how to write code that retrieves the foreign key data when the data from the other table is called?Thanks

How To Write .net Code To Place XML Messages On Queues And Retrieve XML Messages From Queues.

Apr 2, 2008

Hello, please help!!

I have spent days searching the web and forums for an answer to this simple question and cannot find an example.

I have built a service broker application on sql server 2005. The application puts some xml on an incoming queue which is basically a few parameters to be used in a query. This queue will then call a stored proc which does some business logic and puts the resulting results in another queue also in xml.

I have written a test harness in SQL to put messages on the inbound queue and then some sql to retrieve the returned code from the outbound queue.

What I want to do is be able to convert the SQL which does this into .net code to be used by an application. i.e. write in .net some code to put xml on a queue and then write some .net code to retrieve xml from another queue.

I wouldn't have thought this would be a difficult thing to do and would have been done hundreds of times, but unable to find anything to simply send and retrieve XML to service broker queues....

thanks for your help.. its really needed. I found some links, but they are really vague and often doing select statments in service broker or something like this. I don't want to call any sql, just send and recieve XML on the queues.

any example code that does this, would be really helpfull

kind regards,

Help With Converting Code: VB Code In SQL Server 2000-&&>Visual Studio BI 2005

Jul 27, 2006

Hi all--I'm trying to convert a function which I inherited from a SQL Server 2000 DTS package to something usable in an SSIS package in SQL Server 2005. Given the original code here:
Function Main()
on error resume next
dim cn, i, rs, sSQL
Set cn = CreateObject("ADODB.Connection")
cn.Open "Provider=sqloledb;Server=<server_name>;Database=<db_name>;User ID=<sysadmin_user>;Password=<password>"
set rs = CreateObject("ADODB.Recordset")
set rs = DTSGlobalVariables("SQLstring").value

for i = 1 to rs.RecordCount
sSQL = rs.Fields(0).value
cn.Execute sSQL, , 128 'adExecuteNoRecords option for faster execution
rs.MoveNext
Next

Main = DTSTaskExecResult_Success

End Function

This code was originally programmed in the SQL Server ActiveX Task type in a DTS package designed to take an open-ended number of SQL statements generated by another task as input, then execute each SQL statement sequentially. Upon this code's success, move on to the next step. (Of course, there was no additional documentation with this code. :-)

Based on other postings, I attempted to push this code into a Visual Studio BI 2005 Script Task with the following change:

public Sub Main()

...

Dts.TaskResult = Dts.Results.Success

End Class

I get the following error when I attempt to compile this:

Error 30209: Option Strict On requires all variable declarations to have an 'As' clause.

I am new to Visual Basic, so I'm on a learning curve here. From what I know of this script:
- The variables here violate the new Option Strict On requirement in VS 2005 to declare what type of object your variable is supposed to use.

- I need to explicitly declare each object, unless I turn off the Option Strict On (which didn't seem recommended, based on what I read).

Given this statement:

dim cn, i, rs, sSQL

I'm looking at "i" as type Integer; rs and sSQL are open-ended arrays, but can't quite figure out how to read the code here:

Set cn = CreateObject("ADODB.Connection")

cn.Open "Provider=sqloledb;Server=<server_name>;Database=<db_name>;User ID=<sysadmin_user>;Password=<password>"

set rs = CreateObject("ADODB.Recordset")

This code seems to create an instance of a COM component, then pass provider information and create the recordset being passed in by the previous task, but am not sure whether this syntax is correct for VS 2005 or what data type declaration to make here. Any ideas/help on how to rewrite this code would be greatly appreciated!

How To Show Description In Report Instead Of Code (Desc For Code Is In Master Table)

Mar 28, 2007

Dear Friends,



I am having 2 Tables.

Table 1: AddressBook
Fields --> User Name, Address, CountryCode



Table 2: Country
Fields --> Country Code, Country Name


Step 1 : I have created a Cube with these two tables using SSAS.



Step 2 : I have created a report in SSRS showing Address list.

The Column in the report are User Name, Address, Country Name



But I have no idea, how to convert this Country Code to Country name.

I am generating the report using the Layout tab. ( Data | Layout | Preview ) Report1.rdl [Design]



Anyone help me to solve this issue. Because, in our project most of the transaction tables have Code and Code description in master table. I need to convert all code into corresponding description in all my reports.

WHERE (ePRN = @ePRN)
and the code behind which i have to write will be something like thiscmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@eName", ((TextBox)FormView1.FindControl("TextBox1")).Text);cmd.Parameters.AddWithValue("@ePRN", ((TextBox)FormView1.FindControl("TextBox2")).Text);
cmd.Parameters.AddWithValue("@cID", ((TextBox)FormView1.FindControl("TextBox3")).Text);cmd.Parameters.AddWithValue("@eCC", ((TextBox)FormView1.FindControl("TextBox4")).Text);
((TextBox)FormView1.FindControl("TextBox7")).Text = ((TextBox)FormView1.FindControl("TextBox7")).Text + ((TextBox)FormView1.FindControl("TextBox6")).Text + ((TextBox)FormView1.FindControl("TextBox5")).Text;cmd.Parameters.AddWithValue("@sDate", ((TextBox)FormView1.FindControl("TextBox7")).Text);
cmd.Parameters.AddWithValue("@eLOC", ((TextBox)FormView1.FindControl("TextBox8")).Text);cmd.Parameters.AddWithValue("@eTel", ((TextBox)FormView1.FindControl("TextBox9")).Text);
cmd.Parameters.AddWithValue("@ePhone", ((TextBox)FormView1.FindControl("TextBox10")).Text);
cmd.Parameters.AddWithValue("@eMobile", ((TextBox)FormView1.FindControl("TextBox11")).Text);
So is there any way to do it better than this way ??

Nov 21, 2007

I have a report that i've created that has a picture of the image followed by details relating to the image.

What i'm trying to do if possible is for the user to click on the image and for it to open a new window with the full sized image and then close that image and click on a image relating to another image so they could see that full sized.

Is this possible in Reporting Services? or is there a way in which i could do a similar thing?

Storing Images

Jan 24, 2007

Hi, can someone help me with this problem. I have recently downloaded VWD and have been playing around with it a bit. I was windering how do I add an image file to a SQL database. I have used SQL in the past but I have never store an image in it. I can add text data and so forth, but I need some pointers into adding images to the sql database. I want to be able to store the images and then retrieve them to a GridView. I have the images in an image folder within the website, but I do not know how to input the reference or link to the images in an sql table.
A quick example, say I have a table called Images, with the following info:imgID (int)imgDesc (varchar(max)imgFile (img)imgTitle (varchar(20))
To input this in sql I would write Insert Into Images (imgDesc,imgFile,imgTitle) Values ("Large fishy", "", "The Big Fish") what would I need to put for imgFile?
I would really appreciate if someone can point me in the right direction.
