ActiveX Component Installation Is Blocked By IE?
Mar 3, 2010
I have created a ActiveX componed and packed into a cab file
1) Created the setup for Class Library that I would like to be exposed for COM access.
2) Create the CAB setup project taking the Project output from the setup created in the setup 1.
3) Embedded the object tag in a sample html file
Now when I launch the sample html from IE, it is showing an security alert, when I accept the security waning the installation was blocked with the following message.
"winows has blocked this software because it can't verify the publisher"

I have been working on an asp.net web application that calls a third party COM application through createObject method. The application works fine (gets initialized) in Win XP but I am having problems getting it to work in WIndows 2003. I get the "Cannot create ActiveX component" error.
The website works fine in visual studio - the application launches fine. The references added were the interop assemblies which were packed inside a tlb file.
I am aware of the change in default user - ASPNET for iis 5 and Network Service for IIS 6.0. Also I have changed the default permission levels in DCOM config for not just this COM application but all the COM applications by changing the default COM security properties of the computer. I gave almost every user the permissionto launch and access remotely including Network service and everyone.
The other thing I have done was to test it out in IIS 5.0 isolation mode but couldn't get the application work - still same error.
The final thing I have tried was to use IIS 6.0 itself but change the application pool to local system and I am just stumped that even this didn't resolve the error.
Another thing to add is that I cannot register the tlb file using regsvr32.exe command as it is not a dll.

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.

I am trying to stop the data flow when certain conditions happen in the script component. Like if a row in the data set has an invalid date, I dont want that dataset to be inserted in the tables or go through OLEDB Destination, rather I want the entire data flow for that dataset to stop and go back to the control flow page.
I have tried mulitple solutions but nothing worked. Conditional Split ends up inserting the correct rows, but I just dont want anyting to be inserted when one row is bad, where as I do want the entire dataset to be inserted if all rows are good.
How can I fail the component when certain conditions happen int eh script component.

I have a web form that will send a message fine to every email address other than gmail (this one I know for sure) the message is " Delivery to the following recipients failed. " I know this email works since it is mine. I have my own e-mail server and when I send to the same gmail account the message goes through fine (using the same e-mail address in for form and in the e-mail client). Is there some coding I need to add to prevent this form message from being blocked?

Sometimes I would like to be able to update during day time my ASP .Net application. I noticed that quite often updating DAL's (.xsd files) that are in used will block my application (and users). The only way, I found to recover, is to restart IIS but my users do not like it.
Is there some more clean way to update an online server without disrupting the users ?
Could I identified the DAL which are in used and the users using them, so that I could somehow disconnect only these users (My application uses Windows authentication).

I am getting an error saying "ASPNET account is not present in this machine" when I try to install Sitecore on my machine after I installed visual studio 2008..
- My machine is running on windows XP sevice pack 3
- I installed Visual Studio 2008 and .NET framework version 3.5 SP1 on that machine
- I can see that ASPNET User group account Under Users and Groups and it doesn't have "Account is locked out" ticked under general tab
- Also I ran aspnet_regiis -i many times but didn't help; actually I red in one post that I should delete ASPNeT account first and run the script but still didn't help
- when I view http://localhost on IE I can view the ASP home page without any problem but Firefox asks me to enter user name and password.

So bit the bullet and installed vs2010 finally. However, when loading an existing vs2008 project, I am getting this error: "The project type is not supported by this installation." the only thing special about this project is that it's a "web application projects" type. what I've tried so far are these steps, but none of these solve my problem:
(1) run "devenv /setup"
(2) regsvr32.exe "%ProgramFiles%Microsoft Visual Studio 10.0Common7IDEProjectAggregator.dll"

I have a button which has a click event but its not firing on the first click. I suspect its something to do with that i am in dropdown box control so when i click the Button the event for the dropdown box occurs (textChanged) but it forgets about the click event
Of course if i click it a second time it works.
Or if i click somewhere else first so that the event TextChange occurs and then click the Button the first time it executes..
Is this normal and what are more workarounds if any?
basically the TextChange event must fire but the button click event must fire as well.
All the events i am talking about are ASP.NET events.
here is some examples of the events i am using - both the button and dropdown
uxGetData is a button and uxToDate is a dropdown box

XP Pro,aspnet 2, IIS, Oracle I have a primary webpage that displays a tab and some summary data. The tab uses an iframe and the summary data is loaded by an async WebMethod call back to C#. The iframe page takes a short while to load depending on how much data is in there (sometimes upto 20 seconds?). The WebMethod call, or at least the content of it, is very fast. BUT, the WebMethod call won't return until basically the iframe has finished loading.
I've verified through Fiddler that the browser is initiating both requests at basically the same time. It's initiating the iframe call first followed immediately by the WebMethod call within the same second. My understanding is that browsers are limited to only two calls at once.
If I set a breakpoint at the end of my WebMethod call (even commenting out ALL it's guts so it just returns an empty string), that breakpoint won't fire until the aspnet page serving up the iframe has finished. Using threads window, I see both calls at the server. I just don't understand why the server won't actually run the Webmethod call until the first call has finished. I've searched the code looking Monitor.Enter, lock, etc to make sure nobody has inserted any other type of blocking code and I can't find anything. I've basically emptied out the WebMethod call and it just returns a string, but no matter what I do, it just won't return as fast as it can. If I comment out the iframe, then the WebMethod call returns within 2 seconds. With the iframe, it "looks" like the the webmethod call won't return until the iframe has finished.
1) Does aspnet only process one request per aspnet session id? Is it FIFO? I figured the webserver would just process requests and return each request as fast as it can.
2) What else can I do to get that summary data to return faster (but not actually loading and putting the data into the very first primary page) ?
