Configuration :: How To Give Full Trust To Activex Control By Programmaticallytrust To Activex
Jul 30, 2010Currently 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.

Oct 29, 2010I 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.

View 5 RepliesLegacy ActiveX Control Calls DLL Functions ?
Sep 1, 2010Hint: this one might sound complicated, because I am trying to give as much info as possible, but I suspect that I just want someone to tell me "yes, you are correct".
On this legacy system, which dates from 2002, the user visits a web page and uses an RFID reader to read a tag number, which is then written to an input field on the web page.
The only s/w that comes with the reader is a custom DLL, nop .exe.
The very sparse documentation insists that only MSIE be used and that all security relating to ActiveX be disabled.
When I look into the source of the web page I see calls to functions in the DLL.
Now, here's the fun part: I know zilch about ActiveX, I have to make a minor change to the DLL _but_ the VB6 source code has been lost, so I guess that I have to recreate the (seemingly very simple) DLL from scratch - this week.
Decompiling the DLL shows me the functions (locateReader, getTagVal, closeReader). However, by decompiling I can't really know the number or type of the parameters, nor the return values ... and if anyone knows the API they are refusing to share it, but basically it all seems to have been lost in the mists of time as companies went bust, were bought & sold, merged & demerged and the initial DLL might have been written by an external guy, but no one knows who.
So, can I get the function params & type from the ASP page source?
I see things like
Reader = new ActiveXObject("<dllName>.Reader");
Reader.locateReader();
tagVal = Reader.getTagVal();
Reader.closeReader();
So, I would say that none of the fn()s take parameters, that closeReader doesn't have to return anything; it looks like locateReader doesn't return anything either, so I guess that error handling will have to be in the DLL (loop forever with a popup demanding that a reader be attached; and getTagVal seems to return a string.
Does that sound about right? Any other comments (other than lessons to be learned)?
How To Find What ActiveX Control Is Referred On A Webpage
Mar 4, 2010I have developed a web application (ASP.NET Web Forms). One of my customer has very restrictive policies. When he accesses the web page, IE shows this message:
Your security settings do not allow Web sites to use ActiveX controls installed on your computer. This page may not display correctly.
As far as I know, we don't use ActiveX controls on our page. I did a "View > Souce" and did not find anything suspect.
How can I find what part of my page refers to an ActiveX. The application uses jQuery and a few jQuery plug-ins. Is there a tool/add-in like "Fire Bug" that I can use to list the ActiveX controls referred on a page?
Installing A New Version Of An ActiveX Control In Web Application?
Jan 7, 2011I've been tasked to update and install a new version of an old ActiveX control in our Aspx web application .The actual updating is fairly straightforward, but the installing is giving me headaches. Here is what I tried:
In the VB6 editor, get the properties of the ActiveX project, and check off the "autoincrement" checkbox in the "Make" tab.Set the version to 1.0.12 Create a new CAB with the Package&Deployment wizard. Copy this CAB to my website.
Then in the Aspx itself, I update the version of the activeX as follows:
Me.Page.Header.Controls.Add(New LiteralControl(String.Format("<div style=DISPLAY:none'><object id='PrtLabel' codebase='{0}' classid='CLSID:AB61148E-D4B5-4D4B-8867-9E4CE8229B5E' viewastext></object></div>", "PrtLabel.CAB#version=1,0,0,12")))
After this, I delete the prtlabel.dll and prtlabel.inf files from the "c:windowsdownloaded program files" folder.
Problem is, when I then visit the web page and it asks me to install the activeX, it doesn't actually do it (no error message appears though). When I go back to the "c:windowsdownloaded program files" folder, ONLY the prtlabel.inf file has been copied there, NOT the prtlabel.dll file.
Is there a special procedure to put a new version of an ActiveX control in your website?

Web Forms :: Invoke JavaScript Function From ActiveX Control
Mar 4, 2010I 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 1 RepliesActiveX Control Works In HTML, But Not (quite) In ASPX. What's The Difference
Mar 23, 2011I'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)
http://mysite.mydomain.com/controltest/test.html?msg=123
(complains)
http://mysite.mydomain.com/controltest/test.aspx?msg=123
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.

Configuration :: Deploying An ActiveX Control And Marking It As Safe?

The main code is like the following:
[Code]....
The control works if I turn off a lot of security in IE and manually run regasm on the users machine, but how do I automate the process and let it run without the users having to lower their security levels?
Do I need to get the dll signed? If so how do I get it signed and how do I deploy and install it to users?
Ajax Modal Popup Loads Behind The Activex Control?
Aug 4, 2010In a page there is an activex control as well as a button whose onclick opens an ajax modal popup. The problem i face is that whenever the button is clicked the ajax pop up loads behind the activex control and thus it is hidden.So I am not able to use that control at all. I have not found a proper solution to this. I tried a solution where a browser check condition was removed from the ajaxtoolkit code. but no luck. Am using Ajax toolkit version 3.0.30512.1.

Web Page On VPS Can't Create Word Application ActiveX Object
Nov 7, 2012So I have written as part of an application some code that on my clients website pulls some information from SQL server and uses it to create a new file using a Word with bookmarks as a template. It works fine on my development machine, but not on my production server with the error: "Cannot create ActiveX component.: Word.Application". Now I have been approaching this as if it is an issue with Office, but it occurred to me that this might be another issue. Maybe some security issue with ASP.NET? My original thought was it was some kind of compatibly problem as I had Office 2007 on my machine and 2010 on the server.
Code:
Protected Sub btnCreate_Click(sender As Object, e As System.EventArgs) Handles btnCreate.Click
Dim objWord As Object
Dim objDoc As Object
Dim strContractFile As String = "~Documents" & txtContractFile.Text
Dim strContractFilePath As String = Server.MapPath(strContractFile)

State Management :: How To Use Current Session (webpage) In Client Side ActiveX Control
May 3, 2010I'm curently developing web application which uses standard form authorization and, of course, server session objects (quite classic app). Now I'm developing client side component, which base functionality is to allow users to acquire tiif/jpg/pdf document from scanner (client side) and send it to server. Because of scan complexity and need for very user friendly interface i decided to implement Activex object (object written in .net 2.0). Until now all was ok, so I have got activex which succesfully registers and scan documents on client - but i cannot manage with sending files to server.
My concept of sending files was like that:
- preparing Upload.aspx web page wich is used for reciving files sended by POST method and saving files in database (of course to proper save in database i need some current user context information) - in ActiveX i decided to use System.Net.HttpWebRequest object to prepare and send data the problem was third point:
- i thought that in-proc activex object would "derive" web session form web page activex is placed on - but i was wrong (or i made it wrong). Whenever i send request form Activex, in response i got login.aspx page - so it looks that new session is created and new authorization is needed.
I was trying to pass to my Activex values stored in "ASP.Net_SessionId" and ".ASPXAUTH" cookies, as i found that these are the values identifying session and athorized user - but with no luck.
I think, that becaause HTTP is stateless protocol all information needed to "connect to/share" existing session on IIS server need to be included in request data, so there must be way to add these information to request sended from my activex.
I would be very grateful, if someone could provide me information what should i add (headres/cookies/etc... ?) to my request data so it could share session from "parent" web page.
