I tried to update existing image using the code shown below. Then when I retrieve the image file, my image button only shows "X" icon. What is wrong with this code.
Dim filePath As String = FileUpload2.PostedFile.FileName
Dim filename As String = Path.GetFileName(filePath)
Dim ext As String = Path.GetExtension(filename)
Dim contenttype As String = String.Empty
Dim filestr As Stream = FileUpload2.PostedFile.InputStream
I need displaying my image file stored from my database into the image control. I've had read some articles and watch video tutorial which there were perfectly working and I followed it but I wasn't able to make it work. The image control just displayed blank. I used Generic Handler to retrieve the image file from my database based on the articles and tutorials I've got. here are my codes below:
Generic Handler:
Code: <%@ WebHandler Language="C#" Class="ShowImage" %> using System; using System.Configuration; using System.Drawing; using System.Drawing.Imaging;

Got a problem with regards to the file upload control on database updates. The problem is in my CMS, when a user tries to update content for a page it will add null to the fields containing the image path. What I need is for the system to check if the uploader has no image and if hasn't it has to do nothing. It can't add empty strings or null values as this will remove the original image path. Although they still need to be able to do image updates if the uploader has a file(this bits not a problem).
Here is a snipet of code to demonstrate what I'm trying to achieve.
I have done website using Ms access database and VS2005. actually i store image in system.byte[] format in MS access database..so i want to set that image in rdlc background or image tag. Actually I did the following way. [Code].... But I got following Exception ex = {"Value does not fall within the expected range."} and ex = {Function evaluation disabled because a previous function evaluation timed out. You must continue execution to reenable function evaluation.}
I'm trying to display images in a GridView (yes, still this...). [edit] Before I can come to that I have to upload some images to the database.
I've followed this tutorial for the "upload image to database" code (this worked fine for uploading images, but I don't know if the images were converted to byte):
[URL]
and I've followed this tutorial for the "display images in gridview" code (and "retrieve file" from the tutorial below).
[URL]
It doesn't quite work, the GridView shows but without images
Now I'm trying to change the "save file" code according to this tutorial:

but I don't understand everything in it. When I try to upload an image I get an error on this line:
my application is running in visual studio 2005, i used ajax control toolkit for .Net framework 2.0.but now i want to use ajaxcontroltoolkit latest version which is for .net framework 3.5 in my application which is running on .net framework 2.0 and visual studio 2005.how to integrate or use ajaxcontrol toolkit ?because i have some functionality like there is one file upload control and when click button it will take 2 to 3 min for upload so i need progress bar with loading gif file.because of asynchronous postback fileupload control has not file.so i must assign postback trigger to button if i assign postback trigger to button than loading gif or progress bar not working.so i want to use AsynchFileUpload control of newly release toolkit.

I keep running into a problem when trying to connect to my web service. THe problem only occurs when I try to update the database linq to sql file. When I do this and then upload the wcf services and attempt to connect I get this error: Quote: The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.
Server stack trace: at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs, TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs) at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMess age methodCall, ProxyOperationRuntime operation) at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message) Exception rethrown at [0]: at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type) at IService1.GetPollById(Int32 pollId) at Service1Client.GetPollById(Int32 pollId)
If I then revert back to the old linq to sql file it works fine.
I have struggled with this for the last 2-3 days. I have a tab container control with a update panel surrounding it. On one of the tabs I have allowed the user to upload and download files to a SQL Server database. The upload works fine and the download works fine only when I remove the update panel.
I have tried to implement the solution that's provided at the following location...http://encosia.com/2007/02/23/ajax-file-downloads-and-iframes/I had to modify the code a little bit to fit my scenario but it looks like it would work. Is there another way to download files from a database within a update panel?
If there isn't another way to do this what could be wrong with my code...following the example on the encosia site...
Page starting from [Code]....
The code never gets past the if statement with in this java script. Should I put a trigger on the update panel to force a post back. Any help will be appreciated, java script is not my strong point.
Which is the better alternative when allowing file uploads on a page (through a Gridview populated by a coded DataSet)? Store the image itself in the database or to store only the path name to the saved file in file system. If it matters, I do not expect to have more than a few dozen images stored in the database at any given time.
