Sending Uploaded Image To Data Access Class When Storing Image In SQL Server 2005
Apr 20, 2007I am using the 3-tiered architecture design (presentation, business laws, and data acess layers). I am stuck on how to send the image the user selects in the upload file control to the BLL and then to the DAL because the DAL does all the inserts into the database. I would like to be able to check the file type in the BLL to make sure the file being uploaded is indeed a picture. Is there a way I can send the location of the file to the BLL, check the filetype, then upload the file and have the DAL insert the image into the database? I have seen examples where people use streams to upload the file directly from their presentation layer, but I would like to keep everything seperated in the three classes if possible. I also wasn't sure what variable type the image would be in the function in the BLL that receive the image from the PL. If there are any examples or tips anyone can give me that would be appreciated.

Database Access Via COM Objects - V- Database Access Via Stored Procedures
Aug 17, 2000We have been asked to look into using stored procedures with SQL Server 7.0 as a way to speed up a clients site. 99% of all the articles I have read along with all the books all say Stored Procedure should be used whenever possible as opposed to putting the SQL in your ASP script. However one of my colleagues has been speaking to Microsoft and they said that that they were surprised that our client wanted to use Stored Procedures as this was the old method of database access and that now he should really consider using COM objects for data access as itis much faster. Has anyone got any views on this or know of any good aticles regarding this matter ?

Aug 17, 2006Hi,
I want to store an image hyperlink in a sql database but don't seem to be able to do it..is this do-able?
I can store a hyperlink in text format, no problem, but how do I do the same with an image?
I want to use images in my images folder. I can create an image field and set the required options to display images all that is pretty straight forward but trying to display the image as a hyperlink ( actually it's a mailto: link I want to use) seems not to be an option.
The purpose of this is to allow users to upload an image together with their email address and when other users click on the image it fires up their email app. I do not want to have to use a text link.

Retrieving Image From SQL Database
Jul 3, 2007Ok, again, I'm reasonably new to this. I've been trying to display an image stored in SQL in a ASP.NET page. Pretty simple stuff I would have thought. I've read countless examples of how to do this online, and many of them use the same method of displaying the image, but none seem to work for me. The problem seems to lie in the following line of code:
Dim imageData As Byte() = CByte(command.ExecuteScalar())Which always returns the error: Value of type 'Byte' cannot be converted to '1-dimensional array of Byte'.Here's the rest of my code, hope someone can help. It's doing my head in!

I have read many solution over the net, but since I am unable to utilize anyone according to my needs I am seeking help from you people.
I have a table imagedata in sql server 2005 having fields name and imageperson. Name is string and imageperson is Image field. I have successfully stored name of the person and his image in database.
I have populated the dataset from codebehind and bind it to the repeater.
By writing <%# DataBinder.Eval(Container.DataItem, "name")%>I am a able to retrieve the name of the person. But when I pass photodata as
<%#photogen((DataBinder.Eval(Container.DataItem, "imageperson")))%>
where photogen is function in code behind having structure
public void photogen(byte[] dataretrieved)
{
Response.BinaryWrite(datarerieved)
}
But it is giving error at <%#photogen((DataBinder.Eval(Container.DataItem, "imageperson")))%>
The best overloaded method match for '_Default.photogen(byte[])' has some invalid arguments
AND
Cannot convert object to byte[].
Can anyone please provide me working solution with code for aspx page and code behind.

Upload Image To SQL Database
Apr 3, 2006I am creating a update, delete, edit form for my web database. The form works in everyway except that when I try to upload the image to the database it does not go into the database. (I know the pros and cons of storing images in a database. In this instance it is what makes the most since. )
I have to admit I have never uploaded anything to my server or database before (other than plain text). I have read through several articles and have a high level of understanding.
I found an example on a website that used the OnInserting/OnUpdating command. But it is not working. I tried to find another similar example so that I could better understand it and try to fix what must be wrong. I can't find a similar example.
I am posting the code I have below. Any help would be most appreciated.
