Web Forms :: Possible To Synchronize Video With Presentation Slides
Jun 22, 2010
I found a good website to show presentation with video and slides at the same time. The video is nicely synchronized with the slides. I would like to know whether it can be done in ASP.NET web form. If yes, how to do it? What is the logic to implement this feature?

I have what I consider a pretty complex situation that I am not sure if it can even be accomplished via an ASP.NET web application. (I am using aps.net 4.0) But what I want to do is design a "online auction site" that can handle many autions running at the same time. So I can only imagine eBay and all the other millions of auction sites out there are all doing this someway or another. My biggest concern is that I want to make sure the design here to make the site as effiecent as possible. Here is specifically what I am trying to figure out.
I think I need to create an object (per active auction) that stays in memory for the life of the auction. This object would have at least the following information:
Aution ID, time remaining, highest bidder id, bid price, Thread Control Variable, etc...
Now here is the tricky part that I think is vital for auction sites. Lets say you have 500 users on my website that are all watching the same auction and it is getting down to the last second of the auction and they all click to place a bid at the same time. Keep in mind this may also be at the same time hundreds of other users are placing bids for other auctions going on all at the same time.
How do I get all these requests (bids), for a single auction, lined up so that they are processed "one at a time"? But some how I need to be able to make all requests wait in a queue until it is their "turn" then I would need to be able to update the in memory object, write a record into a SQL database and then begin returning information back to each user.
Based on other development languages I have used in the past I know their were objects that I could create that could be used to get multiple threads to run in order (in other words syncronized). Usually it would be a case where I would be listening on a server socket and could do something like ThreadVariable.Lock, <process the request>, thenThreadVariable.Unlock. What that would do, is force all threads that tried to call ThreadVariable.Lock to wait until no other threads had the variable locked then it could proceed. Obviously the code it processes between the lock and unlock should be as quick and effecient as possible so it does not create a major traffic jam.
Because my thinking is this "object" I am referring to as being in memory, most likely will play a big role in answering the question about getting the requests in a "one at a time" situation it may be the focus of the question is more like how would I create "an object" and store it in memory to be quickly and easily accessed?
And even more generically does this even sound like I am on the right track
I think the topic of "communication to and from users" will need to be a completly different thread.

I have a Gridview that is populated with and ObjectDataSource set up to allow anonymous users to populate it. After logging in, the database is filled with the Gridview's data using the following:
[Code]....
The database's primary Key is filled by the "lblItemID" string at the beginning of the loop.
deleting the item from the database keying on this primary key. The gridview deletes the proper row using it's DeleteMethod, but obviously I don't have it set up properly to delete the same PK row from the database.
I really don't want to mess with the DataSource's DeleteMethod (and I'm not sure if this would help at all anyway), so is there a way to look for these deleted ItemId's and remove them from the database while executing this Loop statement?

I'm developing an ASP.NET website that will allow users to view and print Microsoft PowerPoint slides. Right away, I knew that Aspose had a product that would likely allow me to do this. What I'd like to do is look at alternatives just to say to management, "Yes, I've looked at the alternatives and they are". I can't seem to find any other than the open source project on Source Forge which seems to be mostly dead and I'm not even sure if it's something that would meet my needs anyway: [URL]. Is anyone aware of any alternatives to Aspose Slides .NET? Please list them if so. If you are aware there are no decent alternatives, I would find that information useful as well.

We have an ASP.net site where we need to generate PowerPoint slides of the data. The slides will need to include charts and tables. I have come across Aspose.Slides online which seems a good option. What are your experiences with Aspose.Slides? Are there any other options we can pursue?

I need idea of new implementation. I have a client application which will interact with my application. My application needs to count how many slides are available in the powerpoint presentation file and it needs to provide it to the end user. And also user can ask this application to provide only first two slides or 3 and 4th slides to retrieve from the PPT file. How do I approach this. If any one has answer and source code please provide it.

I have this slideshow extender that works perfectly with hard coded images in the page method. However as soon as I try to make the page method get its images from the database it stops working; no images are returned.
I have tried to declare the datatable that the pagemethod uses both inside the pagemethod and in the on_load event. When in the last case I test the datatable contents by hooking it up to a gridview, it shows that it does get its proper data.
Declaring this dataTable as a private static dataTable, outside the page_load, to make it accessible in the page method (like in this --- post http://forums.asp.net/p/1115257/1726736.aspx---) also does not work.
So the page method with hard coded images works and also the query to the database works!

I'm looking at a site with horizontal menu and sub-items for each item. When an item is clicked, a second horizonal menu is presented under the first, with all the sub menu items for that particular main item. I can do this with the asp.net menu? Almost seems like it would require a second menu control under the first.

I have multiple nested GridView controls where I have one field/column that always have one of three values only (0, 1, and 2) and this is editable field. Now, instead of putting this field as a DropDownList for the end-user to choose either one of these values (0, 1, or 2), I am representing each value with a specific clickable image, so the user can click the image to switch among the mentioned field states (0, 1, or 2).
I managed to do this with ImageButton and AJAX. However, the volume of this field is too high, the page is quite big, and the end-user needs to do change the state/value of this field most frequently, which causing a flicking issue in the page and slowness (because the code is done by AJAX, so in the server side) where the customer is not accepting it.
how we can rectify this issue; for example using javascript coding (but I need to get the selected value from code-behind)? I found the AJAX Toolkit ToggleButtonExtender which is very good and not causing the flicking/slowness issue, but unfortunately, this ToggleButton has only two states while I need three states option.

I have the following scenario:
A server with a number of different clients on different networks. Clients will have to synchronize data with the server.
Just imagine we have a simple data table on the server. The client has the same table schema and works locally but at a certain time of the day it must upload and synchronize with the server.
Was thinking maybe in doing the following. On the client have two extra columns:
Ej:
- synchronized (Boolean, default to false)
- Time it was synchronized (date time).
- Have a wcf service on the server.
Whenever it needs to synchronize it calls the service. The service then updates data on the server. The client will wait for a response which will inform whether the synchronization took place or not. If it did it updates its local table, setting synchronized to true and the time.

I know that when working with a session in Java, you were always supposed to surround use of the session with a synchronized block incase the user would load your page with two browsers at the same time.

how can I synchronize sessionID over multiple second-domain servers? For example, I've got servers(you can log-in into server swarm at any of these), [URL], [URL], [URL] and if you log in at one of them, the login information (+anything else) should persist along them. How can I provide SessionID to other domains? (session itself is stored on sql server shared across the services).

I used the Database Publishing Wizard to create a copy of my live SQL Server database for testing purposes. Both the live and test databases are hosted by my ISP.
What is the easiest way to transfer design changes from one database to the other without altering the data (assuming that the design changes are compatible with the existing data in the target database)?
Any proposed solution would have to be available via Visual Web Developer 2008 Express or SQL Server 2008 Development Edition.
