i uploaded a new version of my website. and some users complained that they see some page i changed very very wrong. anyway after a refresh they see it fine. i think its because my css file got cached by them on an earlier time...why isnt the browser downloading the css file by himself on first load?..

In my application I've allowed users to upload Excel 2003 .xls files, and import them into a Gridview. This has been working fine using the following connection string:
[Code]....
Now my users are using Excel 2003, 2007 or 2010, I need to allow the newer file extensions (.XLSX) to be accessible too.
Therefore, within the connection string above I presume I could change the Excel version from 8.0 to 9.0 or 10.0 respectively, but is there much difference between Excel 2007 and Excel 2010 files?
If so, is it possible to 'detect' the Excel file version so that I can use the appropriate connection string to read the data from the files?
How can you upload the time that the file was uploaded to the database?
And how to show the results that are made that day?
"SELECT x,y,z aspnet_Upload WHERE Date = @Date"; ??
In asp.net, we have uploaded a .jpeg file and saved this as bitmap image using following code
HttpPostedFile uploadFile;
System.IO.Stream stream = uploadFile.InputStream;
using (System.Drawing.Image imgSource = System.Drawing.Bitmap.FromStream(stream))
{
System.Drawing.Image.GetThumbnailImageAbort myCallback = new System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback);
using (System.Drawing.Image imgThumbnail = imgSource.GetThumbnailImage(imgSource.Width, imgSource.Height, myCallback, IntPtr.Zero))
{
imgThumbnail.Save(filePath, System.Drawing.Imaging.ImageFormat.Jpeg);
imgThumbnail.Dispose();
}
imgSource.Dispose();
}
stream.Close();
stream.Flush();
stream.Dispose();
After upload, if we perfrom delete operation it throws error. We are following code to do so;
if (File.Exists(filePath))
{
File.Delete(filePath);
}
The exception says:The process cannot access the file 'abc.jpg' because it is being used by another process.
I have a server control that I developed which generates navigation based on a third party CMS API. Currently I am caching this control using the PartialCaching attribute. The CMS uses cache key dependencies to invalidate the cache when a user makes an edit, however in the case of my server control it does not get invalidated and the updated navigation will not show up until the cache expiration set by the PartialCaching attribute.Here is my two part question:
What is the proper way to programmatically cache a server control, without using the PartialCaching attribute, and adding a cache key dependency?
Is it possible to continue to use the PartialCaching attribute and add a cache key dependency?
I have Visual Studio 2008 installed on this workstation with SQL 2000, 2005 Express, 2008 Express and I think 2008 R2 (not sure if that is a version itselve or not)
I will call that workstation HOME
I created some tables in SQLEXPRESS through VS2008.
I worked on this project on another workstation that I just installed VS2008 annd SQLEXPRESS 2008 and I know that was R2
Installed Visual Studio 2010 trial edition between the thiem I made the tables on HOME and tonight for the first time since that install
I am now getting the "cannot be opened becuase it is version Version 661. This Server supports version 655..."
What to do now?
I can opened SQLExpress 2008 management studio and it is running.
So is my SQL 2000. The problem seems to be that after the VS2010 install neither VS2008 or VS2010 can connect to the SQLExpress 2008
What do I do now?
I can't remove sql 2000 because it is tied to several 3+ gig databases that will not work in Express.
I usually use WebMatrix to manage my database (sdf file). I wonder if it can be possible to manage this database with SQL Management Studio 2008? When I try to open it with SQL Management Studio 2008 I get the error:
Incompatible database version. What's wrong?
BUT When I create a new sdf database with SQL Management Studio 2008, I have no problem for open it again with SQL Management Studio 2008 but if I try to open it with WebMatrix it doesn't work...(server not found?)
I've got a web application that runs of a state server. It looks like soon it may need to distributed and there will be two web servers behind a load balancer.
This works great for session state but my next challenge is Cache
My application leverages heavily of cache. I understand ASP.Net 4.0 will be offering more here but nothing much has been said about the how too.
There are two challenges that I face
1). Each webserver will have its own copy of cache whereas it would be more efficient to put this to a third server the same as session state is put to state server.
2). The real challenge is keeping cache in sync if a simple dataset derived from the database is changed my code dumps that cache item and reloads the cache. That's all well on one webserver but webserver number two wont know to drop that particular cache item and reload it. This could cause some unexpected problems in the application.
For scenario number 2 I could attempt to do some smart coding so server number two knows to dump the cache and reload it.
My guess is someone else has already been here before and there's probably a better implementation approach rather than writing extra code.
Does anyone know how I could achieve the goal of keeping Cache in sync between multiple webservers or even better farm Cache management to another server?

View 5 RepliesI need to create a custom web control which will be a part of a class library. This custom web control implements the upload functionality. I have implemented this with a web user control where I have a fixed path to a page in the web project where the upload of files take place and it works just fine.
The created control in this class library is used in the web project. How do I post the uploaded file to a page, say SomeClass.cs, in the class library.
