How To Invoke A JavaScript Through A Thread

Feb 23, 2011

I 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?

C# - Invoke A Control To Set A Property?

Mar 23, 2010 can't update page from event handler

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

How To Invoke Code Within A Web App That Isn't Externally Open

Sep 3, 2010

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.

Invoke Asynchronous Method Call From .NET?

Jul 20, 2010

I'm currently working on a web site which involves a data upload process. The file is currently uploaded to the server method is called (in app_code) where ultimately a DTS package is called (via a web method) to load the data into a database and perform some validation on it.The client has specified that they don't want to have to wait for the DTS package to execute (execution time is less than 5 minutes) so it appears that I need to call the method asynchronously. The user will probably logout or close the browser window while this task is running so I believe I'm unable to run this on an thread.

AJAX :: Invoke AutoComplete Extender Using A Button?

I need some serious help here since I have been struggling with this issue since last week.I have a requirement to actually have a drop down which would display only the values matching the text typed in by the user hence yes, the AutoCompleteExtender is a solution.This was based on a feedback to our site in production from our users. Now, the issue is that they also would like to have a functionality of something like "Show All" in the same drop down. Something like when you click the down arrow button in a DropDown control and it shows all the values. I have been trying to fake this using a simillar button with autocompleteextender.So far, I have had success in invoking the webservice using the following code:

Web Forms :: Invoke JavaScript Function From ActiveX Control

Mar 4, 2010

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(){ ..... }

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.

Select Item In CascadingDropDown Via JavaScript And Invoke Update?

Mar 17, 2010

In code-behind I can do this to select something:

// Select item in first DropDownList
myCascadingDropDown_1.SelectedValue = itemValue_1+":::"+itemText_1;
// Select item in second DropDownList
myCascadingDropDown_2.SelectedValue = itemValue_2+":::"+itemText_2;

How can I do this in JavaScript?


I can select my desired item in the first dropdownlist. The problem is however, that new values based on that selected item (it is a CascadingDropDown, remember?) don't show in the second dropdown so I can't select anything there. I would need to somehow invoke the update method of the second dropdown manually.

Security :: Get Custom RoleProvider To Invoke Its Methods On Every Page Load

Jun 18, 2010

I had a post here [URL] that I need to expand on now. I have a few web pages that need to check for a certain role on each page request. I have a custom Membership Provider and a custom Role Provider (called CustomRoleProvider - very original - I know) that I am using to do this. When a user logs in, the CustomRoleProvider.GetRolesForUser() method is called automatically (by the urlAuthorizationModule). When this method gets called, I am currently adding a role to the roles string array that allows/permits the user from viewing the web pages of concern based on certain qualifications that are determined elsewhere in the code (i.e. the database is queried to see if the user has rights to visit certain pages).

This approach only gets me half way because the user's roles are only checked once at login. When I wrote my previous post, I thought the CustomRoleProvider was broken because it wasn't calling the IsUserInRole() method on each page request. According to Microsoft, "The IsUserInRole method is called by the IsUserInRole method of the Roles class to determine whether the current logged-on user is associated with a role from the data source for the configured ApplicationName." (that information comes from this page:

[URL] Reading that description I thought it was being called automatically on each page request. This is not correct. What I need to know how to do is to get a method in the CustomRoleProvider that returns a boolean to be called automatically on each page request so I can update the user's roles if they change while the user is logged into the web site. For example, if the user has rights to visit page A and then five minutes later his rights are revoked, he can't visit page A again unless he contacts an admin to reset his rights.
