C# - Retrieving Many Huge Sized EPS Files And Converting Them To JPEG In Application?

Mar 23, 2010

I have many (>600) EPS files(300 KB - 1 MB) in database. In my ASP.NET application (using ASP.NET 4.0) I need to retrieve them one by one and call a web service which would convert the content to the JPEG file and update the database (JPEGContent column with the JPEG content). However, retrieving the content for 600 of them itself takes too long from the SQL management studio itself (takes 5 minutes for 10 EPS contents).

So I have two issues:-

1) How to get the EPS content ( unfortunately, selecting certain number of content is not an option :-( ):-

Approach 1:-

foreach(var DataRow in DataTable.Rows)
{
// get the Id and byte[] of EPS
// Call the web method to convert EPS content to JPEG
}

or

foreach(var DataRow in DataTable.Rows)
{
// get only the Id of EPS
// Hit database to get the content of EPS
// Call the web method to convert EPS content to JPEG
}

or

Any other approach?

2) Converting EPS to JPEG using a web method for >600 contents. Ofcourse, each call would be a long running operation. Would task parellel library (TPL) be a better way to achieve this?

Also, is doing the entire thing in a SQL CLR function a good idea?

EDIT :- Unfortunately, I have to do this in the ASP.NET application itself and doing that in a separate process like Windows service is not an option.

Web Forms :: Uploading Multiple Files Using Single Insert Query?

Web Forms :: How To Upload Multiple Files Using Single FileUpload Control

May 7, 2015

I had implemented FileUpload code. In which for every particular Id, it creates Folder/Directory (if not exist) on Page _load.Then inside that particular Id's folder it will upload single or multiple files.

HTML:

<asp:Label ID="LFileUpload" runat="server" Text="Upload File"></asp:Label>
<asp:FileUpload ID="FileUpload1" runat="server" Width="300px" AllowMultiple="true"/>
<asp:Button ID="btnUpload" runat="server" Text="Upload" OnClick="UploadFile" ValidationGroup="none"/>
<asp:Label ID="LMsg" runat="server" Text="" Visible="false"></asp:Label>

C# - Why Does ReSharper Need To Scan All Files When Converting A Property To An Auto Property

Mar 4, 2011

Is there any difference between accessing a property that has a backing field

private int _id;
public int Id
{
get { return _id; }
set { _id = value; }
}

versus an auto-property?

public int Id { get; set; }

The reason I'm asking is that when letting ReSharper convert a property into an auto property it seems to scan my entire solution, or at least all aspx-files.

I can't see any reason why there should be any difference between the two from outside the class. Is there?

Forms Data Controls :: Using Multiple Tables Within A Single DataSet And Single SqlDataSource?

May 19, 2010

I have a stored procedure that returns 3 tables within the single recordset it returns. If I set a SqlDataSource to get data from this procedure, it works, but it only returns the first table. I want to have a GridView display the data from the 2nd or 3rd table using a SqlDataSource, but I can't figure out how to specify a particular table.

While there are some posts discussing this out there, I can't get a definitive answer about whether or not this is even possible (?). In a worst-case scenario, I can create another SP that only returns the 3rd table - but that creates a little maintenance headache that I would prefer to avoid.

DataSource Controls :: Using LINQ To Pull Out A Single Value From A Single Result Row Of A Join Query?

May 25, 2010

For context: First of all, I am new to LINQ, as I have been using SubSonic for quite some time now.

I have two tables, Users, and Affiliates. They both have a very typical schema. The FK that joins them is the UserId field, which is in the Affiliates table. I want to create a LINQ query that pulls the Username from the Users table using the AffiliateId value. The AffiliateId is a primary key of the Affiliates table.

I have tried to accomplish this using many variations of the following code:

[Code]....

In the above query, I expect to get a single row result set. However, I instead receive the entire table of results.

How can I make this work? I have yet to see an example or article out there to do what I am trying to do.

Can Server .html Files Using Razor As If They Were .cshtml Files Without Changing The Extension Of All My Pages

Feb 24, 2011

I manage a large asp.net site which has previously been converted from static html site to asp.net. For several reasons (mainly SEO) we decided not to rename all the files to .aspx back when we originally converted the site. This was very easy to do by simply adding the buildProvider and httpHandler to the web.config.

<buildProviders>
<add extension=".html" type="System.Web.Compilation.PageBuildProvider"/>
</buildProviders>
<httpHandlers>
<add path="*.html" verb="*" type="System.Web.UI.PageHandlerFactory"/>
</httpHandlers>

Now I am upgrading the site to use Asp.net WebPages with Razor cshtml files. I can rename all the files if necessary, and use url rewriting to make the urls stay the same, however it would be much easier if I could just configure the web.config to tell it to parse .html files as if they were .cshtml. I have searched around quite a bit, and could not find anything equivalent to the PageHandlerFactory for razor pages. It appears as though it is just an internal mechanism in the .net 4.0 ISAPI handler.

The site is currently running on Windows 2003 server and IIS 6. We will be upgrading to 2008/IIS 7.5 in the near future, but I'd prefer not to wait for that. Is there any way to get the .html files to be parsed by razor as if they were .cshtml files?

Configuration :: ResourceManager And Resx Files - Files To Display Items In Multiple Languages

Oct 13, 2010

I have an application that uses resource files to display items in multiple languages. My app uses quote a lot of javascript and the alerts need to display in the local language. To do this, I have created an http handler which will read the keys and values of the culture-specific resource file and write them to a JSON array which is then embedded in the page in a script tag, the messages can then be accesses using, for exmaple:

Message.Error (en-GB = "Error", fr-FR = "Erreur")

The messages http handler works great in development, however when I run the application on a test server, I get the error: Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "Resources.Alerts.resources" was correctly embedded or linked into assembly "App_GlobalResources.b0n9j90e" at compile time, or that all the satellite assemblies required are loadable and fully signed. The code that I use to acccess the resource file is:

ResourceManager manager = Resources.Alerts.ResourceManager;
ResourceSet resourceSet= Resources.Alerts.ResourceManager.GetResourceSet(Thread.CurrentThread.CurrentCulture, true, true);

Where Resources.Alerts is the type that contains my multi-lingual definitions. The build action for the Alerts.resx file is set to "Embedded Resource". Any ideas why this works locally but not on my test server, am I missing something?

Send Form Files To The Server Just To Get Summary Filesize Without Sending The Whole Files?

Dec 24, 2010

I have a form with 10 file inputs. They can contain 10 random files with random sizes. If I send these files to ASP.NET server with this code:

var count = HttpContext.Current.Request.Files.Count;
var TotalSize = 0;
for (int i = 0; i < count; i++ )
{
HttpPostedFile postedFile = HttpContext.Current.Request.Files.Get(i);
TotalSize += postedFile.ContentLength;
}

And as you can see I didn't save the files on the server, will this code just calculate the summary of files without need to receive the whole file from the client (And therefore it would be very fast)?
