Looking For Aspose Slides Alternatives
Sep 23, 2010
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 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 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!

All i need is to generate a (x) number of slides on one page the number of slides will depend on the number of rows returned by a dataset.

Im looking for some input on a validation problem i have. My demands for validation are:
1. Able to do database checks
2. Error messages are custom and imported from other localized source as stringvariables(NOT resource files).
3. DRY serverside and clientside validation.
As far as ive seen data annotations dont work well under these cirumstances, custom attributes are needed just to be able to output the strings(wonder why this wasnt thought of). This isnt a dealbreaker but as ive tested sofar custom attributes must be added in the global.asax wich i 1. cannot get to work in the CMS im building this on and 2. i dont want to have to edit the global.asax everytime the scripts are implemented. Serverside this solution works fine though. From what ive read IDataErrorInfo should not be used? So havent really checked how to get this rolling with client-side either.
My thought was using custom service layer validation with xval but documentation is very poor to the extent i could find any(couldnt find any real nfo on how to implement xval with your own code, ie not using the autgened client-side metadata wich leads to the annotation problem described above). So i have a hard time finding any working solution other than to build something 100% custom.
Do anyone have a solution or perhaps some information or can steer me in any direction on the best way to getting this done in a good fashion other than building custom?

I'm considering purchasing a resharper license but would like to know if there are any possible alternatives to resharper and how would you rate these compared to reharper? It doesn't necessarily have to be a free alternative but I would just like to know how good equivalent products are.

I am looking for an alternative to using UDP multicast on the .NET Framework and am looking for suggestions.I need to send messages to several web servers running quite a few ASP.NET applications. These messages would be one-way only, coming from several different machines. UDP multicast would be perfect except that I can't use it due to it requiring administrative rights. Seehttp://stackoverflow.com/questions/1941463/asp-net-multicast-udpclient-problems for details as to why.Is there something else that would work in a similar manner, allowing multiple applications to receive broadcast-type messages?

What is your opinion of DataSets vs. just stubbing out custom classes and working with those? What are other alternatives?

In my web application, I have a dynamic query that returns huge data to datatable and this query is often recalled with different parameters. So database is exhausted. I want to get all record with no parameters to an object, and perform queries (may be with linq) on this object. So database will not be exhausted. Which objects can be used instead of datatable?

Are there any other ViewState alternatives? I've heard a lot Like Session, holding the state of some of the page's controls' state and getting destroyed the moment the user leaves the page. I know I'm describing ViewState itself, but I'm looking for a pattern of sorts or suggestions so I can avoid ViewState altogether. An example of how I'm using it is where I'm storing the contents of my grid (A list of ViewModels) to ViewState. This helps to know which entries are dirty, which ones have been modified, their indexes, the currently selected objects, etc.

title isn't as detailed as I hoped but I have a few questions. Traditionally I've always been a mixed mode person, storing PDFs and other things into the file system with pointers from my SQL DB to them.
Recently I've heard more people storing files into the DB directly and wonder if I'm storing files around 100-200MB in size, will I run into a lot of issues? Are there ways to compress the files other than perhaps zipping them up and storing the zip?
Finally, something I've always wondered about but never really found a good work around for... if I decided to continue with the mixed-mode storage solution, and these I need to retrieve these files for use on a website, how do I secure these files so that someone can't just randomly come and retrieve these files off the server by guessing files names, etc?
I did one work around once where I stored a set of PDFs to a non-web directory like c:pdf and setting permissions for the web account to access them. This allowed me to retrieve them using the references in the DB and provide some garbled filename so people couldn't retrieve it themselves but this all seems rather complicated.

In my experience, web.config files are widely reviled. In particular, I have found them difficult to manage when you have multiple environments to support, and fiddly to update due to the lack of validation at update-time and the verbosity of XML.

I have read a lot of posts describing why it isn't good practice to return heavy objects like DataTable/DataSet to the client from WCF. However, there doesn't seem to be much discussion about the alternatives (or maybe I'm not looking in the right forums).
My problem is this: I've tried to convert my DataReader/DataTable into a List<List<string>>, where List<string> represents the data in each row, but get an error at the point when the data is being sent to the client. A simple List<T> or a one-dimensional array gets returned without any problems. But whenever I try to return a collection of collections, there seems to be an issue. I don't know until runtime what my DataReader would look like as different stored procs are called based on user selection from a web form.
What am I missing here. Is WCF not able to handle collection of collections (I know that multi-dimensional arrays are not supported)?

I have a multiple database operation, Have three tables (MSsql) and need to delete one row in each table in one operation, one after another. (Three functions, three rows of code). Everything is working as it should be, recently I was advised to use a transaction scope, which should guarantee the safety of deletion from all 3 tables together.
Here is my new code:
[Code]....
Locally all worked just fine, the transaction scope worked well, but when I have uploaded my application to my hosting server, I got an error of: The partner transaction manager has disabled its support for remote/network transactions. (Exception from HRESULT: 0x8004D025).I talked with the host support, they tried to do something, then I got this error: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).
After a 2 days, They have contacted me, they said it is not possible to disable some restriction, that will allow an access to this operation, because I'm using shared hosting, and I need to upgrade my plan to VPS. VPS is a very expensive for me, and I can't afford it, What I'm looking is a some similar way of doing the same operation as transaction scope do, that may work at my hosting, At least I would like to try something else. Is there any additional way for the transaction scope?

We are developing a web app that will have a pretty complex user and permission system. The general idea is that we have 3 levels of security:
a simple user - that can only access basic data that is in a data repository
a manager - that can open up data repositories
a superuser - that can open up repository factories.
Each repository contains various data types(text, images, etc etc). We are looking for authentication methods that will allow us:
1. Scalability.
2. Customization.
3. To create permissions that will effect the GUI + deny access to certain pages.
4. To create predefined roles - that will allow for easy setup of new users.
5. To create custom roles for specific users - allowing them permission sets that are different from the predefined roles.

I'm looking at options for rendering PDFs on the server to avoid the user having to download them (they're big docs) and/or have a PDF reader installed and configured (audience is not tech savvy). The Google Viewer and Scribd are nice examples, but I'm not interested in making the PDFs available on the web (for Google) or storing them on another party's servers (Scribd).
My favorites right now are FlexPaper and PDFWebViewer.NET but I wanted to see if I'm missing any other options. Most of the related SO questions on this topic are somewhat dated, so maybe there's something new?
Any other options to check out?

Currently, I'm using a Table control and manually retrieve data from the database and then dynamically create the Table to display the data. However, I find Table control hard to format/style. GridView looks easier because we have a skin created for gridview which will give a uniform look. But the problem is GridView is designed to work with Data components instead of manually data retrieval.
