AJAX :: How To Detect When A Media File Has Finished Loading In Modalpopupextende
Dec 8, 2010
I embed wmp, swf, and qt in a modalpopupextender. Some of the video files take a long time to load so a given player's window stays empty for too long. I think I should be able to have the player hidden initially and display an animated gif in the modalpopupextender and then when the video files completes loading I'd hide the gif and show the player (or simply manipulate the corresponding z-indexes).

Is there a way or a browser that would tell me which media or code in my website that would cause the "Security Warning" in IE or FF browser?

I have an UpdatePanel with a repeater in it that is re-bound after a user adds an item to it via a modal popup. When they click the button to add a new row to the repeater the code-behind looks something like this:
protected void lbtnAddOption_Click(object sender, EventArgs e)
{
SelectedOption = new Option()
{
Account = txtAddOptionAccountNumber.Text,
Margin = chkAddOptionMargin.Checked,
Symbol = txtAddOptionSymbol.Text,
Usymbol = txtAddOptionUsymbol.Text,
};
Presenter.OnAddOption(); // Insert the new item
RefreshOptions(); // Pull down and re-bind all the items
mpeAddOptionDialog.Hide(); // Hide the modal
// ... Make call to jQuery scrollTo() method here?
}
This works fine and the new row will show up quickly via the UpdatePanel. However, there are often hundreds of rows and where the new one is added is based on the current sorting column used. So, I wanted to take this as a chance to use the sweet jQuery ScrollTo plugin. I know that if I give it the ID of my overflowed container div and the ID of an element within it, it will smoothly scroll straight to the users newly added row. However, there are two problems:
I need to find the appropriate row so I can snag the ClientID for it. I need to execute the jQuery snippet from my code-behind that will cause my newly updated repeater to scroll to the right row. I've solved #1. I have a reliable method that will produce the newly added row's ClientID. However, problem #2 is proving to be tricky. I know I can just call ScriptManager.RegisterStartupScript() form my code-behind and it will execute the JavaScript on my page.
The problem I'm having is that it seems that it is executing that piece of JavaScript before (I'm guessing) the newly refreshed DOM elements have fully loaded. So, even though I am passing in the appropriate jQuery line to scroll to the element I want, it is erroring out for me because it can't find that element yet. Here is the line I'm using at the end of the method I posted above:
string clientID = getClientIdOfNewRow();
ScriptManager.RegisterStartupScript(this, typeof(Page), "ScrollScript", String.Format("$("#optionContainer").scrollTo("{0}", 800);", clientID), true);
What do I need to do so I can ensure that this line of JavaScript isn't called until the page with the UpdatePanel is truly ready?

I might be wrong about what is actually happening here but i have 3 Html.dropdownlists. And im using jquery to handle filtering which does actually work. However, there is some odd behaviour which i think might be because data isnt finished loading before the next function is called. For instance: Some background. Company: Owns several field offices Field Office: Owns several facilties So logically, when you change company, field offices should change, which then changes facilities.
$(function () {
$(document).ready(function () {
var cid = $("#CompanyId").val();
$.post("/ManifestSearch/GetFilteredFieldOffices", { id: cid }, function (data) {
$("#FieldOfficeId").loadSelect(data);
});
var fid = $("#FieldOfficeId").val();
$.post("/ManifestSearch/GetFilteredFacilities", { id: fid }, function (data) {
$("#FacilityId").loadSelect(data);
});
});
});
Now, when the page loads, everything looks fine. All the dropdownlists have the correct data.
When i change company, this calls.
$(function () {
$('#CompanyId').change(function () {
var cid = $(this).val();
$.post("/ManifestSearch/GetFilteredFieldOffices", { id: cid }, function (data) {
$("#FieldOfficeId").loadSelect(data);
});
var fid = $("#FieldOfficeId").val();
$.post("/ManifestSearch/GetFilteredFacilities", { id: fid }, function (data) {
$("#FacilityId").loadSelect(data);
});
});
});
This changes the field offices to the correct list, however facilities changes to whatever field offices was set to before the company change occured. I dont know enough about jquery to figure out exactly what is going on, but my instinct tells me that the two posts are happening at the same time, and the second post happens before the first one is finished.

I'm writing an ASP.NET webapp that will copy the contents of a CD to a network share. I need to check periodically if the copy job is finished.
One way of doing this is checking the network share folder to see if the file size has changed since the last check, but that seems kind of dodgy. Does anyone have a better idea how to do this?
EDIT
some more explanation: Basically I'm calling a JsonResult action method every 5 seconds, called getStatus(source,destination). This method needs to check the following:
- if the source dir is still empty, copy cannot start --> return status "waiting"
- if the source dir contains files, copy can start -_> call copy method + return status "copying"
- if the destination dir contains files, and file size stays the same, copy is finished --> return status "finished"

I want a Javascript function to be called automatically after the UpdatePanel has finished updating its contents. I don't want to use:
Sys.WebForms.PageRequestManager.getInstance().add_endRequest
and then call a JS function. This is because I have more than one update panels and I'll have to write all the condions to check which UpdatePanel was actually called and then do something. Can something be done using Triggers in UpdatePanel. Kindly let me know how this can be done.
It would be great of you could post a sample code too.

I have an ASP .NET 2.0 (4.0 is an option) page that I've embedded the Windows Media Player to using OBJECT tags.
The player is connecting to a Windows Media Services publishing point on the Web server. This is on a 2008 server.
Everything works great, see it here: [URL]
If I understand correctly, the information the player is showing in its status bar comes from the ID3 tags of the current track. Continuing on this line of thought, the ID3 information must be coming to the player from the media server. Correct?
What I want to do is collect and use the information about the track that's current being played. I'd like to be able to create a custom display for the current track information. I'd also like to put a custom value in the track information to look up additional information about the artist/track from a database.

I've been thrown into the middle of this project without knowing all the background. If you've got WTF questions, trust me, I have them too.
Here is the scenario: I've got a bunch of files residing on an IIS server. They have no file extension on them. Just naked files with names like "asda-2342-sd3rs-asd24-ut57" and so on. Nothing intuitive.
The problem is I need to serve up files on an ASP.NET (2.0) page and display the tiff files as tiff and the PDF files as PDF. Unfortunately I don't know which is which and I need to be able to display them appropriately in their respective formats.
For example, lets say that there are 2 files I need to display, one is tiff and one is PDF. The page should show up with a tiff image, and perhaps a link that would open up the PDF in a new tab/window.
The problem:
As these files are all extension-less I had to force IIS to just serve everything up as TIFF. But if I do this, the PDF files won't display. I could change IIS to force the MIME type to be PDF for unknown file extensions but I'd have the reverse problem.

Is this problem easier than I think or is it as nasty as I am expecting?

I am using VSTS 2008 + C# + .Net 3.5 + Silverlight 3.0 + ASP.Net to develop a Silverlight application (a video media player) in browser and the function is simple, just use MediaElement to play a remote video file.The remote server is Windows Server 2008 + IIS 7.0 + IIS Media Bit Rate Throttling Control.Since the request media URL can be discovered (e.g. from traffic sniffer), and I want to know how to prevent from download directly from the Url? i.e. I want end user to use my Silverlight media player application in browser to play the file, prevent them from download to local directly. Any easy and quick solution or reference code/documents?

In Visual Studio 2008 I have a Class Library project (called Media) to which I added a Web Reference (not a Service Reference) to a third-party web service (wsdl). In the Class Library project a proxy class is created for using the service along with several classes for the types used in that service.
I also have a second Class Library (called Sync) that references the first one. And then I have a Web Site project that references the second class library. All of this is .NET 3.5
So Web Site > Class Library (Sync) > Class Library with web service reference (Media)
I want to step into the generated code, so I fire up the web site in IIS 7.5 and trigger the call to a method in the second class library (Sync) that in turn should call the web service proxy. I was fully expecting to hit the breakpoint, but instead got an exception:
Unable to generate a temporary class(result=1). error CS0029: Cannotimplicitly convert type Media.WebService.multiValuedAttribute to Media.WebService.multiValuedAttribute[]
Why is ASP.NET trying to generate a temporary class? Don't I already have the generated class from the first Class Library (Media)?

I'm developing a website that has modular section. I would like it that when a new aspx (and aspx.cs) file is placed in a subdirectory of the application that I can ask the class some information...The idea is that when the file is placed in the directory a new menu item is added to the menu. To do that I need to "ask the class" for its name, icon, description, etc. Is there a way to determine the class that is defined in codebehind file and to instantiate an instance of it?I know I could look for and parse a config file for each plugin but I would rather not have to go that route.

using vb.net/asp.net 2005
I am opening and reading and I need to detect the encoding of the file that I am reading. There are different system users who will be using different encoding in their files so I have no control over this.
[Code]....
While the default encoding normally works there are special foreign language (non-English) characters that are not being read correctly, instead there are garbage characters in their place that I see "myString" above. Good foreign characters are visible in the file but the result in myString are unreadable garbage characters that are not valid.
I have researched this and it has been suggested to determine the encoding of the file and then use that encoding, but I have not been able to find out how to to do this.
so in a nutshell: how can I use vb.net to detect the encoding of an excel file?

My question is similar to http://stackoverflow.com/questions/194579/how-to-detect-when-a-user-has-successfully-finished-downloading-a-file-in-php but I have to do the same using IIS, ASP.NET and C#.
None of the methods in the HttpResponse class provide feedback if the data was sent or not, TransmitFile just does its job (or not) and does not provide any means of knowing the result.I was thinking of using the .Filter property but then again, the filter is based on the HttpResponseStream which does also not provide any feedback.
