Web Forms :: Accessing Window Control Library .dll From .aspx Page (ActiveX)

Oct 29, 2010

I have a control in a 'window control library' which handles - 'drag and drop' files from computer to a listbox control, I then reference this .dll in .aspx (See code below). Now, when i try to access this through webserver for drag
and drop files i get following errror - The type of the first permission that failed was : System.Security.Permission.FileIOPermission.

How do I handle this, so that drag and drop of files can happen over the webpage residing at webserver.

Web Forms :: Accessing User Control Property Value Across 2 Aspx Page?

Dec 20, 2010

There is one user control say uControl.ascx. This has a public property Message. There are 2 aspx pages Default.aspx and Home.aspx which has the user control uControl.ascx. When a sumit button from Default.aspx is clicked some action takes place and the value for Message is set and then execution is redirected to Home.aspx. In Home.aspx the value for Message is lost.

Is there anyways that the value of Message is retained for both the aspx pages?

ActiveX Control Works In HTML, But Not (quite) In ASPX. What's The Difference

Mar 23, 2011

I'm trying to use a third-party ActiveX control on our intranet ASP.NET site, and I've run into a problem I can't figure out.

Expected behavior: The control expects to see a specific variable in the URL ("msg"). If you provide it, it works. If you don't provide it, it complains that the value is missing.

If I put the control in an HTML page, it works fine. But if I then change the page's type to aspx, the control acts as if the variable isn't there. The control still loads and runs; I'm not getting any permission or safety messages. But it complains that "msg" wasn't provided on the URL.

In other words, if I try these URLs, the first one works fine; the second one gives me the "you didn't provide the msg parameter" complaint:

(works fine)


I know the aspx version is being processed by the server before being sent to the client, but there aren't any server-side commands or tags (it's the same file, just copied and renamed). As far as I can tell, the resulting page that is sent to the client is exactly the same.

Is there something about aspx vs html that would cause the control to not be able to get that variable? I can see it fine from javascript that I add myself. Here's the content of the page. Not much to it. If I get this working I intend to add some aspx tags and code, but there's no point yet.

ActiveX Control Test
<OBJECT ID="control1" CLASSID="..." CODEBASE="..." >

Configuration :: How To Give Full Trust To Activex Control By Programmaticallytrust To Activex

Jul 30, 2010

Currently I have written the Activex Control for RFID USB reader and calling that one in ASP.NET web application. The Activex Control is working fine when I will give the full trust permission for particular IIS URL in

1. Open Control Panel > Administrative Tools > .NET Framework 2.0 Configuration

2. Expand Runtime Security Policy > Machine > Code Groups > All_Code

3. Right Click All_Code and click New...

4. Create a new code group, I named mine MyProject_FullTrust_Zone

5. Choose the URL condition type and specify the path on the network where the apps will be deployed.

6. Choose Use Existing permission set, and set it to Full Trust.

Alternative way of giving permission for an Activex Control is

1. Open Visual Studio Command Prompt

2. Run the command caspol -machine -addgroup 1. -site <ip address> FullTrust Doing this it works fine.

Whenever my web site will open, it will ask the user to give permission for the Activex Control using Allow or Cancel Button in browser. This type of functionality I have seen some web site which takes input from the user to allow the ActiveX Control.

MochaUI Window Loading ASPX Page In Iframe And Communicating With Window

I am hoping someone has experience with this, but I am loading a window from a link on my main page. The window loads an ASPX page via the window's loadmethod of iFrame. The aspx page has its own update panel on it and I was wondering how I can call the window's "spinner" / process indicator while the page is processing. I have looked at the documentation on some online information about it but I am not sure how to implement it.

Accessing Controls In An Aspx Page?

Jun 28, 2010

We have some code which is designed to build up a key/value pair of controls on a ASP.NET webforms page and their values. We use the "Controls" collection and recursion to build up this key/value pair.

The only issue is that ascx controls don't appear to come back in the "Controls" collection. Instead we get the controls on the ascx.

Something similar to the following code:


The subCtl is never a ascx control. Is there a way to get a list of the ascx controls on page or better still a different collection that contains both types?

Vb.net - Accessing A Windows Application From An ASPX Page?

Aug 2, 2010

I have an aspx page and I want to access an application on the client after seeking user permission. Both the windows application and the website are to be made in VB.NET.

EDIT: Here is the problem. From my .aspx webpage in vb.net, a visitor clicks on a link on my site, and if my winform is not already loaded on their desktop, it is then loaded with the users permission. This application should auto-load on the user's site at boot up time and always be in the background running. Make it an extremely thin client, taking the least cpu and bandwidth from the user, and running as a silent background process until needed.

Whenever the user visits one of my many websites, IN ANY BROWSER, somehow - the app running in the background communicates with the .aspx on one of my sites, and exchanges a silent username password identifying client winform app to the online .aspx app on my website.

Then the .aspx on my site PASSES a url such as "www.somewebsite.com" to the app running in the background, the background app then does a http request from the client's computer, not from my .aspx server, so the client's cookies and ip are visible to "www.somewebsite.com" server. The client collects the html for that page, stores it as a string, and also saves the ascii of that webpage as another string.

Both strings then are PASSED BACK to my .aspx website that the client is visiting, and the .aspx app then stores these results in a database.

Accessing Silverlight Object Data From Aspx Page?

Jul 29, 2010

I am new to silverlight and I am wondering if it is possible to access silverlight object data from the aspx page that host it. Or have silverlight write to a hidden field on the page on client side.

What I am trying to do is to use silverlight to upload file via WCF (client to WCF Service directly instead of posting data back to the web server then forwarded to WCF service). When uploading a large file, user can still do some data entry etc. And once the upload is done have it write some data return by the WCF service to the aspx's hidden field and postback to the server on submit.
