calling CreateObject from web service...getting exception: Cannot create ActiveX component

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :ADO.Net

I have created a web service in VB 2005 and this ws calls CreateObject to access an api. I can successfully call CreateObject from an application but not the web service(using the same code). I get the following error:


System.Exception: Cannot create ActiveX component.
   at Microsoft.VisualBasic.Interaction.CreateObject(String ProgId, String ServerName)

   at WebServicePAM.getPositionData.getPamString() in  c:\inetpub\wwwroot\WebServicePAM\App_Code\getPositionData.asmx.vb:line 60


WebServicePAM is the web service.


I appreciate any suggestions. I have gone through the IIS settings and but have not been able to make any changes that will allow me to call CreateObject successfully.

ActiveX component can't create object: 'Scripting.FileSystemObject'



I have a problem, on classic asp website.

This line of code is raising an error

Set objFile= CreateObject("Scripting.FileSystemObject")

This is the error

Microsoft VBScript runtime error '800a01ad'

ActiveX component can't create object: 'Scripting.FileSystemObject'

My System

Windwos Server 2003 SP 2

The application pool for this website is using a user with administrator rights.

I already reinstalled Windows Script 5.7 for Windows Server 2003 and restarted the server.

Crystal reports 8 is installed on the server, I read some articles that said Crystal reports 8 could be the problem, buy they dont't say how to solve it.

I have installed RegMon as requested on this article but has been useless, can't find anything.



VS2005 calling VS2010 asmx service returns empty string


Anyone have any experience with this?

We are using VS 2005 for the front end, and vs 2010 for the web services part (asmx), not wcf yet.


Web service works just like the vs2005 when run locally, no problems.


Connecting to it from a test app returns an empty string. Connecting to a 2005 app doesn't!

Anyone run into this before or have a suggestion? Surely vs 2005 can connect to web services from a later version?






Cash Drawer - Method Open threw an exception - Windows Service

Hi All, I'm getting the following exception while calling Open method of Cash Drawer object. Method Open threw an exception.  Could not read the device name key's default value, or could not convert the Programmatic ID it holds into a valid Class ID. Code:   class Class1 { CashDrawer _uniCashDrawer1 = null; DeviceInfo cashDrawerDevice1 = null; PosExplorer posExplorer = new Microsoft.PointOfService.PosExplorer();   public void ClaimCashDrawer() { cashDrawerDevice1 = posExplorer.GetDevice("CashDrawer", "testDrawer"); if (cashDrawerDevice1 != null) { _uniCashDrawer1 = posExplorer.CreateInstance(cashDrawerDevice1) as CashDrawer; if (_uniCashDrawer1 != null) { _uniCashDrawer1.StatusUpdateEvent += new StatusUpdateEventHandler(UniCashDrawer1_StatusUpdateEvent); _uniCashDrawer1.Open(); _uniCashDrawer1.Claim(0); _uniCashDrawer1.DeviceEnabled = true; } } } }   Tha above code works fine if you put the code in WindowsApplication in all POS systems. The same is working if you put the code in Windows Service in all other POS systems. The same is not working if you put the code in Windows Service in Aures Galeo POS systems.  Thanks in advance.

Calling an asp.net web service from jQuery

As I have post it in earlier post that jQuery is one of most popular JavaScript library in the world amongst web developers Lets take a example calling ASP.NET web service with jQuery . You will see at the end of the example that how easy it is to call a web service from the jQuery. Let's create a simple Hello World web service. Go to your project right click->Add -> New Item and select web service and add a web service like following.   Now modify the code of web service like following. [WebService(Namespace = "http://tempuri.org/")][WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)][System.ComponentModel.ToolboxItem(false)]// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. [System.Web.Script.Services.ScriptService]public class HelloWorld : System.Web.Services.WebService{ [WebMethod] public string PrintMessage() { return "Hello World..This is from webservice"; }} Here please make sure that [System.Web.Script.Services.ScriptService] is un commented because this attribute is responsible for allowing web service to be called by Client side scripts. Now to call this  web service from jquery we have to include jQuery Js like following. I am already having in my project so i don't need to include in project just need to add script tag like following. <script type="t

calling a web service on a remote server from an ASPX page

hi, I want to call a web service on a remote server. I've done "add web reference" in my project, and VS2005 has created the .discomap and .WSDL in the App_Web_Reference folder. When I try add the namespace representing the web server (the name I created when I added the web reference) by "using XXXXX;" the code does not compile because XXXXX is not defined. Have I missed any steps? thanks, -me

calling a web service on a remote server from a ASPX page (web site project VS2005)

HI,I am maintaining a web site project in VS2005 and have to call a new web service on a remote server. I've done add web reference, and created the .wsdl and .discomap files in the app_webReference folder.  When I try to create a object representing the web service in the code ( wsnamespace.serviceName ws = new wsnamespce.serviceName(); ) the code wouldn't compile.The web site project is already calling other web services. When I right click on the type representing the web service and "go to definition" it takes me to a proxy class (derived from of course SoapHttpClientProtocol) in the metadata. I think this is what's missing for  the new web service i'm trying to call. Have I missed any steps?Thanks in advance.-me

Error calling WCF service that is returning list.".Debugging resource strings are unavailable ......

Ok.this is just making me frustrated... Here is step by step of what I am trying to do (& not able to) 1. I am calling WCF service hosted in a SharePoint 2010 site from a silverlight app in same domain (So no cross doman I guess). 2. I use Linq to Sharepoint for querying the DB. 3. I am having a list "machines" in Sharepoint 2010 that is having a lookup column from Other list called "part" 4. My WCF method GetAllMachines() works perfectly well when it skips the lookup column "partname" & returns List of type machineitem. 5. But problem occurs when I add machineitemobject.parts.partsname in my Linq to Sharepoint query . My service gives the error not found Async_ExceptionOccurred] Arguments: Debugging resource strings are unavailable." 6. Note that return type of my Method is List<machinesitem> 7. The point to note here is that I use SPMETAL tool to generate the LINQ class that maps the lists . So When I try to query the lookup column it tries to add List item of the type class & that is what causing the error. Is it because I am not using datacontract in my service (but it returns the strings & all private members of machines list e.g. name,title etc) Is it making the attribute Serialisable will solve the error ??? I am kind of lost in it ...Plss help!!   Thanks

WCF Service stops after throwing a unhandled exception :no user is logged on.

Hi All,       I have written a WCF service which is hosted as a Managed windows service. I consume this service in a web application. The service is built using a httpBasicBinding and security Mode ="none". I'm now getting the following exception, after which the service stops  "An unhandled exception ('System.ComponentModel.Win32Exception') occurred in CMMonitorService.exe [1812]. Just-In-Time debugging this exception failed with the following error: Debugger could not be started because no user is logged on." I had tried changing the security mode to Transport/Message. with windows credential then I get a access to the path denied error. Can anyone provide hint on what am I missing and what would be the appropriate security mode and client credential to use along with basichttpBinding?

Service Operation - Get proper data when browsing the service, but not when calling the service from

Hello, I recently implemented a service operation in an attempt to pass some filter parameters to a data service (a user guid and an organization, actually, for impersonation of a user on the service's call to the application). I successfully added the service operation to the data service, and I can browse the service and see the data filtered as I expected. However, when I call the service operation from the Silverlight client, I don't get any results, even though I should. Am I missing something? Code below if it's helpful. Thanks! Service Operation Definition: [WebGet] public IEnumerable<opportunity> filteredopps(string userid, string org) { /*Define the connection with the impersonated user*/ CrmConnection crmc = CrmConnection.Parse("Authentication Type=Passport; Server=https://" + org + ".crm.dynamics.com/" + org + "; User ID=myuser; Password=mypassword; Device ID=mydeviceid; Device Password=mydevicepassword"); crmc.ImpersonatedUser = new Guid(userid); var crmOnline = new DataContext(crmc); List<opportunity> uplist = new List<opportunity>(); crmOnline.UsingService(service => { var query = from o in crmOnline.opportunityopportunities select o; foreach (opportunity thisopp in query) { uplist.Add(thisopp);

Search service is not able to connect to the machine that hosts the administration component

I encounter the error above when trying to set up Sharepoint Server Search. I have tried both setting up search manually through Central admin (just selecting default for everything) as well as through Powershell (using this: http://stsadm.blogspot.com/2009/12/creating-sharepoint-2010-enterprise.html). I'm using the farm admin as Search account as well as account for Application pools, so I guess permissions should not be the issue.Creating new Search service application seems to be successful, but when going to Searchadministration after creation, then System status displays the error above. Event log does add any info and just displays same error message ("SearchApi.cs throws exception:The search service is not able to connect to the machine that hosts the administration component. Verify that the administration component 'db397ab0-d9b0-46c4-9077-dc8be62bf586' in search application 'TNS Enterprise Search Service Application' is in a good state and try again."). I have found this http://blog.fpweb.net/sharepoint-2010-server-search-troubleshooting/ stating that the solution is not to use MSDN version of Windows 2008, but does give any explanation why.Any ideas would be appriciated.Best regardsThomas
