Hi, Well, story goes like this: I need mechanism for authentication/authorization for .NET 2.0 based web service. There is a webservice exposing number of methods. I want only authorized users to call its methods. Authorization is done against custom database. I have very short time - can anybody suggest quick + EASY tutorial / book reference using which I can easily implement the solution? I do not want to send Soap Auth headers/ user name - password with each and every request. Regards,

Good evening, Well I am responsible for designing the architecture of an application which is supposed to extract data from a web service, cache is locally and perform analysis and show results to the user. Initially the team has tried to make the application in ASP .NET, but due to large size of results, it is not feasible to operate over HTTP mode. Now I am working on following idea: - Application will download the data from website (using web service) and cache it locally with expiry time marked - I will perform analysis in off line mode and show results to the user. User then can run what-if scenarios of the data as well Functional requirements includes, data security (as data is pretty sensitive) and ROLE based web service access. I am reading : WSE 3.0, CAB and Smart Client Architecture. Any other suggestions? Regards, :: Platform = Microsoft .NET 2.0

Here I have gathered all the things which should be considered or performed during the development planning phase and during development of an enterprise application. Here by development planning phase I mean the time when all the client requirements are well understood by the team and they have finished the RS and are now just about to kick start the development. Please note that these observations are based upon my limited knowledge and experience. I will highly appreciate if you review them and extend the list. If you think, any other step is required, please edit this post and add accordingly. Also, please do not confuse them with standard software development practices. It is something, a bit different. All software houses have their processes defined, shouldn’t there be one for such activities? Rather I think many places do have got some. Anybody to share any experience? To read the list, please visit my blog. http://weblogs.com.pk/fahad/archive/2005/02/02/1333.aspx[^] If you want to comment/add anything, please visit the wiki at http://www.asquare.info/wikka/ThingsToDo[^] I am looking forward for positive additions. ------------------- Therez No Place like ... 127.0.0.1

hmmm... Response.Redirect send the redirection instructions for the respective page only. Whenever a browser encounters a page containing frames, it reads the sources of frames and then request them separately. During request, if it gets redirection instruction, it changes the source and palce the new page. You can use JavaScript to complete this tast. The script may look like... window.frames("FRAME_NAME").document.location = "new_page.aspx"; or window.frames("FRAME_NAME").src = "new_page.aspx"; or window.frames("FRAME_NAME").source = "new_page.aspx"; or window.frames("FRAME_NAME").location = "new_page.aspx"; I can't remember the exact code, please try both... eff_kay ------------------- Therez No Place like ... 127.0.0.1

Salam All, ASP .NET came up with a revolution in web development. PostBack is one the features ASP .NET which enables developers to write server side event handlers. The inherited problem of this feature was losing the focus after PostBack. This problem becomes very annoying if you are developing a business screen on which almost every text box requires a PostBack. This problem has been solved in ASP .NET Whidbey.

Hi Frankly speaking, what ever one says, Microsoft technologies will always remain problem-matic.. specially with versions... they don have seamless integration. Deployment is always always an issue. But I still love .NET!! Anyway folks, my problem goes like this... I am reading and updating excel sheet using ADO .NET. Everything is working fine on machine, but on server it is all messing up... I connect to sheet using the string called... Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties='Excel 8.0;HDR=YES;' But whenver I try to execute insert command, following error occurs...

I think... - to avoid security mishaps - to avoid delay in service (i.e. what if a local account is logged off, service will have to shut down with it) - to impose security constraints and limitations on resource access Good Day; fadee !! ------------------- Therez No Place like ... 127.0.0.1

Hi... If one wants to access ODBC DataSource in ASP .NET, it must be "System DSN". Reason: ASP .NET WP is executed under separate limited right based user. If you will create the "User DSN", it would be fine for the windows based applications but not for ASP .NET as ASP .NET user (which is kind of passive) will not be able to access it. However, if you use "User DSN", it is accessible under Windows Application for the particular user for whom DSN is defined. fadee... ------------------- Therez No Place like ... 127.0.0.1

www.salcentral.com www.xmethods.com and there was another very cool webservice which provides delayed FX rates. I can't remember it at the moment but I will let ya know as soon as I remember it. Btw, check out the above said. They are basically kinda brokers. They also present some free FX Rate services. Have Fun, fadee!! ------------------- Therez No Place like ... 127.0.0.1

hmmm... yes, I there is no need to install Access driver on client machine. If no office is installed, it will work. I remember that I have tested this and it was working fine. MS Access installation would be required if you are creating objects of certain ActiveX components exposed by Access. But I am very much sure you are not doing so. So, I think it will work fine. Also, another guess, I think to access Access Database, MDAC (or watevva it is) is required on client machine, and Windows XP by default contains this. Another supporting argument: What MS Access installation has got to do with database connectivity? On servers, Microsoft discourages the installation of MS Office products. And all MS based servers still support Access connectivity. So bottom line: No need to worry about. Good Luck fadee! ------------------- Therez No Place like ... 127.0.0.1

Yes I know Microsoft has provided provider for OleDB ... but still I must use ODBC to connect to a foxpro database file. The file is called clients.DBF The DSN created using Microsoft FoxPro VFP Driver (*.DBF). The DSN is called ClientDB. I am using following to connect to the ODBC source... ---------------------------------------- Dim c As New Odbc.OdbcConnection("BackgroundFetch=Yes;DSN=ClientDB;UID=;SourceType=DBF;Collate=Machine;SourceDB=c:\Inetpub\wwwroot\App\foxpro_files;Exclusive=No") ---------------------------------------- When I use this code in Windows Based application, it works fine. Connection is opened and my application can read the data. But when comes to Web Base application... it gives following error which is Way Beyond my intellect ... ------------------------------------------------------------ ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Data.Odbc.OdbcException: ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified ----------------------------------------------------------- Can Anyone Help me ...

there exists two ways to solve such problems. Iteratively Recursively Iteration is very difficult to write and VERY difficult to cover all the cases. Iteration is efficient and have less memory consumption. Recursion is very easy to implement (atleast for geeks) and easy to cover all cases. But it eats up the resources. But, I still prefer recursion. good luck. eff_kay ------------------- Therez No Place like ... 127.0.0.1

If you still are facing this problem and do not seem to find the solution, try re-installing .NET Framework... and its still does not work, try re-installing IIS. Good Luck. eff_kay ------------------- Therez No Place like ... 127.0.0.1
