View 3 Repliesi need to save multiple documents stored in SQL server as Image type to disk.
What i want to do is "backup" all files in a table (column) to disk, zip them and Response.TransmitFile(FilePath) to client.
I could use C# ot VB but that would require a lot of connections to database or a lot of server memory and i don't want that, becauze there are a lot of files to be saved Since SQL can write files to disk i was thinking about saving those files to disk directly from sql. Something like when u're doing a backup

View 6 RepliesI'm using Cute Editor for ASP.NET for the first time, and it's occasionally refusing to insert or update a record. Basically the records are just composed of a bunch of HTML and text. So far I can't detect a pattern to the problem and I'm wondering about my data type.
I tried VARCHAR(MAX), NVARCHAR(MAX), and NTEXT, doesn't seem to fix it.
So what is the best SQL data type for HTML?
And could that be causing CuteEditor to refuse to insert/update records? Or something else?

In the VS2005 environment, when I test my session to make sure the page redirects to the main page (itself) if the session is null, it works. There is no error.
The function I use for this is:
[code]....
However, when it is in the production environment in IIS 6.0, when the session has timed out, and I then do a postback by doing some slider control, I see the page reload but immediately thereafter, it throws a Server Error exception of : Object reference not set to an instance of object.
Looking at the stack trace, the event occured:
AJAXEnabledWebApplication1._Default.Slider1_TextChanged(Object sender, EventArgs e)
however, why is it that the Slider1_TextChanged event fired even even after during page_load, the page was told to do a response.direct ?? shouldn't the entire page have gone through a full-page refresh life cycle ? why did it continue on to attempt to raise the Slider1_TextChanged event?
I have a webservice, it has few webmethods. when i create a client proxy and invoke the methods to check its response, i am getting this error. Can someone tell me what things can i check to know the cause of this? The error is not saying much hence blocked on this.
