AJAX :: Running Web Service From Javascript?
May 18, 2010I'm trying to learn AJAX but I am having trouble getting things working. I downloaded an example app from the web that was written in C# and have got it working perfectly, the next stap was to convert it into VB but for some reason this does not work. I keep getting a "Error: 'myServices' is undefined " error message on the web page. Try as I might I cannot cure this and I know it is something so simple i'm just looking past it.
I'm trying to get some autotext functionality working but I've cut the code right down just to try and get it working, everything seems to work fine apart from the webservice call which returns the 'undefined' error. If I click the button on the web page the code behind is invoked and the webservice code is also run without problems. I just can figure out why I can't run the webservice directly from the web page.
The code
Default.aspx html/javascript
<%@ Page Language="VB" AutoEventWireup="True" CodeFile="Default.aspx.vb" Inherits="_Default" %>

AJAX :: Update Page From Long Running WCF Service
Jan 12, 2010I have a long-running WCF service that I need to call, but I would like to do is to open modal window (modal popup extender) that simply shows progress and stops the user from interacting on the page until the service returns. What I was trying to do was the following:
1. Click button to activate the process which calls a method in my code-behind.
2. This method opens my modal panel with some pretty animation.
3. I call my WCF service asychronously so that the UI will refresh.
4. Service ends which calls my delegate I setup.
5. My delegate method would then refresh the page with results, and dismiss the model popup.
WCF / ASMX :: Running A Web Service User Service / Domain Account?
Mar 28, 2011Is it possible to run a web service as a particular user/service account in the same way a Windows service can?I have a service account used for connecting to the DB and want to run the webservice under this account as the users using the webservice won't have DB access.The way I see to do it is to include the Impersonate option in the Web.config file, but is there any better way to do this?
View 1 RepliesAJAX :: How To Update Label When We Are Processing Code In The Background For Long Running Process
Aug 25, 2010I have Requirement to update the label text as we are processing the code (Long running).
Example:
I have Label and button on aspx page.
On button Click Iam calling the AppCode which is going to do long work for me.
I want to update the label text from the appcode (which should reflect in the page then and there.)
I have tryed to pass the text value to the label but it shows the changed text only after the event for the button click is finished.
I tryed using timer but as soon as i click the button the refreshing stops.
I tryed progress template and UpdateProgress without success. (I know we can update at the start and end of proccess using this)
I dont want to use iframe (I know we can do using iframe)

View 2 RepliesVisual Studio :: Running Service Based App?
Apr 16, 2010here's my issue. I'm trying to run service based applications from Visual Studio. My previous workstation died, and I got a replacement, and I can no longer run the service based apps from Visual Studio, so obviously there's something that I neglected to reload. The specific error I'm getting is:
Cannot start service from the command line or a debugger. A Windows Service must first be intstalled ( using installutil.exe) and then started with the ServerExplorer, Windows Services Administrative tool, or the NET START command.Going through debugger, I eventually get the error "Service <appname> was not found on computer .."The DOS environment does not seem recognize the installutil.exe command.
Separate Service For Processing Long Running Tasks?
Jan 12, 2011I would like to makea windows service. whenever the user of my ASP.NET application has to do a time-consuming task, the IIS would give the task to the service which will return a token(a temporary name for the task) and in the background the service would do the task. At anytime, the user would see the status of his/her task which would be either pending in queue, processing, or completed. The service would do a fixed number of jobs in parallel, and would keep a queue for the next-incoming tasks. In addition there would be a WinForms application for system administrator that would allow adding special ADMIn tasks such as "Clean orphaned files" or "archive data of inactive users".
Can you point me to something that can jump start me on this as a whole concept - I know I can google for windows services and I am able to do it myself from scratch but time is of the Essence so maybe you know of something that is already there and i can use block to build out of.
