I have sql server database in which I have lot of contact person and their telephone numbers. these contact numbers is viewed by user on asp.net form in gridview control, its working fine. User filter the numbers dial the numbers to client through telephone set.
Now I am thinking to merge the call dial and receive funcationality through asp.net form like user have asp.net form have some telephone dial up control, search the number and dial the call on button click event. To talk with client user has headphone.
I am having a ASP.net web application which is hosted in an internet server. Now i got a requirement to integrate this website with a computer telephony infrastructure. The details are as follows.
The user will be located in a building having TAPI standard, LAN - CTE infrastructure enabled telephone system and the logged-in user should be able to connect to the phone line (extension no:) within the same building through the browser. When a call comes to that phone line, a popup should appear in the users browser displaying the number of the caller. I am having the following doubts in implementation of this functionality
How should I connect (communicate) my application with this LAN - CTE infrastructure? The LAN - CTE infrastructre is simply an API having no web services exposed from their side for this purpose. So think I will have to write an extra wrapper class just above the LAN - CTE infrastructure to facilitate this.
Do I really need to connect to the telephone line across the internet as this logged user and the extension no: will be in the same local network?
I want to understand the interaction of telephone with webforms application.
In order to do that I want to create a small application which will be able to receive multiple calls at a time, place them in a queue and then forward calls one by one to a call answerer.
It should also be able to retrieve the Caller Id i.e number from which the call is being made.
How this may be achieved?
If there is any ready made solution available with source code pls provide links.
I have a form for the user to add a Contact's details. Within this form I have fields to enter telephone, mobile, fax numbers etc.
Each have a separate textbox for country code, area code and number. Basically, what I want to do is have validation on these fields so that all or none of the textboxes are filled.
So if the user just adds a number in they are required to enter also the country code and the area code. Or if they don't enter any of the details then the validation will not kick in.
When an ASPX page needs to make a call to a potentially long-running operation (lengthy DB query, call to a remote webservice, etc.), I use RegisterAsyncTask, so the IIS worker thread is returned to the pool, rather than being tied up for the duration of the long-running operation. However ASMX webservices don't have a RegisterAsyncTask function. When an ASMX webservice needs to call a potentially long-running operation, how can I implement the same behavior as RegisterAsyncTask? Note: the ASMX webservice is implemented as a script-service: returning json to a direct jQuery/ajax call. Therefore, I cannot use the "BeginXXX" approach described by MSDN, since that implements the asynchronous behavior within the generated client-stub (which isn't used when calling the webservice directly via ajax). EDIT: Adding source code: implemented the BeginXXX/EndXXX approach listed in John's answer. The synchronous "Parrot" function works fine. But the asynchronous "SlowParrot" function gives an internal server error: "Unknown web method SlowParrot"
I've created a C# function which extracts data from an mssql database, formats it to a json string and returns that. Now I need to make a call from my javascript (jQuery) slider through an aspx page that is related to the C# code file. I have actually never done anything like this before, from what I could tell by googling I need to use xmlHttpRequest, but how exactly do I make the function get hold of this string? It would be awesome if someone had some example code that shows how this works.
Am I missing something? I'm trying to do a simple ajax call using jquery to a web service on my site and I get a 500 error every time when I make the call from the master page. Has no one ever made an ajax call from a master page or am I just crazy and extremely deprived of sleep?Example:
I have a try-catch inside a method that is called asynchronously. When an error occurs, inside the catch I have a Response.Redirect because I need to redirect to the login page.
This is my issue.
But my problem doesn't involve things that expire, so the idea of a timer isn't the best way to resolve it.
I have an asmx web service, and every time I try to call a static method in another project (which is a class library), I get an internal server error 500.
I have a list of items that loads when I call the page controller and I have an Ajax.BeginForm that calls the same (Index) Action. If the Action sees that it's an Ajax request (Request.IsAjaxRequest()) then it returns a partial view. I even have a div that contains a message about the results loading. That all works fine, but my results can sometimes take awhile and I'd like to hit the page first and then make the Ajax request so the user sees the page quickly and sees the "loading" message. I know I could click my filter button (triggering the ajax call) using jquery on document.ready, but is there a more MVC way to do this?
using the bing map API, can I make a server-side call and get lat/long for a given city? I can do it on the client side using JavaScript, but I need something more robust in this case and want to use the server side.
When we set allowpaging=true and specify the pagesize=xx, and when we change the page of the gird view then, does paging in gridview make a database call when its page gets changed ?
I have a page, in my web app, that need to make a call to a web service that reside on the same network of the web server, but the machine with the web service is not directly reachable from the internet. can I set a local ip address in the web config file? es: 192.168.9.2 Or I must only set a public ip address?
I have a div called address which as a textarea. When I click a hyperlink, it toggles the div up and down. After clicking a an asp.net button the div collapses which is fine, but I noticed the url turns from [URL] to [URL] and now the toggle does not work. Here is the script:
I have a system set up to lock certain content in a database table so only one user can edit that content at a time. Easy enough and that part is working fine. But now I'm at a road block of how to send a request to "unlock" the content. I have the stored procedure to unlock the content, but how/where would I call it when the user just closes their browser?
I'm having a simple ASP.NET application hosted on my local IIS6, under Vista.It contains a button that when I click I execute a piece of code for recognizing the text in a WAV file (using the System.Speach.Recognition.SpeechRecognition class) and display the text in a label.
The code works great on a desktop application, and it almost works on the web one... I say almost, because if I debug, I can see that the recognizer returns the correct text from the WAV, I can see that I am finishing the handler for the button click with no error, but nothing gets displayed in my page, and the page appears like loading... it's hanging, or something... No errors, no timeout, nothing. Just loading...
I don't know if this detail helps, but in order to make the piece of code that was already working on the desktop application work on the web application, I had to set the identity of the ApplicationPool of my application to LocalSystem (security breach, I know). Otherwise, I would have received a Access Denied error (0x80070005(E_ACCESSDENIED)).
