I have to fullfill a requirement where my activeX control (developed in c#) need to invoke a callback JavaScript function asynchronously (or) synchronously (or) in both ways. I can handle the context using threads. JavaScript:
function handler_1(){ ..... }
myActiveXObject.registerCallBack(handler_1);
Where in ActiveX control, I need a function "registerCallBack" to accept the argument. But I have no clue how to invoke that registered JavaScript function from my ActiveX control. By digging MSDN forum, I found something as script.GetType().InvokeMember("myJSFunctionName", BindingFlags.Instance | BindingFlags.InvokeMethod | BindingFlags.Public, null, script, null);
the above line throwing me an exception Unknown Name etc. I do have the definition for "myJSFunctionName" in javascript and I got the script object from the document object.

View 3 RepliesI've just finished implementing a modal dialog login popup for my ASP.NET website. The experience is similar to what you get with [URL]. When you log in, you get a fancy popup modal dialog (provided by the JQuery Tools Overlay control). The dialog is an ASCX file in the Master Page, so it's available globally. It uses a PageMethod to validate the current user. If the validation succeeds, I call window.location.reload(); in the PageMethod's success callback.
This works great when logging in on a page that doesn't require authentication, but what about when non-auth users are trying to navigate to a page that requires auth?
Is it possible to modify my web.config file so that instead of redirecting to a SignIn.aspx page for non-authenticated users I simply invoke the modal dialog instead?
Let's say a non-authenticated user is on Default.aspx which doesn't require auth. He wants to navigate to "Add.aspx" which does require auth. What's the best way to handle this with a modal dialog popup?
If I have to use a dedicated page, I guess I'll just have a SignIn.aspx page that invokes the dialog when it loads and if authentication succeeds, it'll use JavaScript to redirect to the destination page.
But ideally, I'd like to do the login from the Default.page and then redirect to "Add.aspx" with script.

View 1 RepliesI have a thread that runs querying a DB and returning some values. If this values satisfyes a condition, I want to raise a message box (javascript alert) for the client side.
In my system, users can post some tasks in DB, and the thread is going to constantly query the database to check if user has things to do. If user has, the system must alert him through a message box.
I've done javascripts invokings with ClientScript.RegisterStartupScript, and Attributes.Add for buttons. But now I want to call the javascript functions (wich will alert the user that he has things to do) from the midle of a sub (that is executed in a thread), without a submit, load or click event. How can I do it?

and it's been answered! My only problem is I don't really understand the solution. How does one Invoke the control when setting the property.
I have a label control but there doesn't seem to be an Invoke property/method on it.
I tried this...
PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(Label1);
PropertyDescriptor myProperty = properties.Find("Text", false);
myProperty.SetValue(Label1, "my value");
but that seemed to be the same as
label1.text = "my value"
which didn't work
Is it possible to invoke setup file in asp.net web application? for example, run the web application (like [URL], select the setup file and upload to server and invoke it(from the server setup will be executed), user enter the required details and install it, after installation completed site will be refereshed.
Note: I think not possible to use process.start method, because error will be produced in IIS (after hosting in IIS). from the development point its working (run the code using VS2010).
On my local machine with the default ASP web server I am able to browse my web service's methods, which have with prompts and an invoke button.But when I deploy this same code to an IIS server and I browse the asmx page I just get a descritpion of the methods.
The web server is running windows 7 and IIS 6.
for example, you are caching data within your ASP.NET web app that isn't often updated. You have another process running outside of the app which ocassionally updates this data, when you do this you would like the cached data to be cleared immediately so that the next request picks up the new data straight away.The caching service is running in the context of your web app and not externally - what is a good method of calling into the web app to get it to update the cache?
You could of course, just hack a page or web service together called ClearTheCache that does it. This can then be called by your other process. Of course you don't want this process to be externally useable or visible on your web app, so perhaps you could then check that incoming requests to this page are calling localhost, if not throw a 404. Is this acceptable? Could this be spoofed at all (for instance if you used HttpApplication.Request.Url.Host)?
I can think of many different ways to go about this, mainly revolving around creating a page or web service and limiting requests to it somehow, but I'm not sure any are particularly elegant. Neither do I like the idea of the web app routinely polling out to another service to check if it needs to execute something, I'd really like a PUSH solution.Note: The caching scenario is just an example, I could use out-of-process caching here if needed. The question is really concentrating on invoking code, for any given reason, within a web app externally but in a controlled context.
