Creating DCOM object of a VI in MATLAB fails

Hi,
I've been trying to remotely control a LabVIEW VI within MATLAB from another PC.
My specifications are as follows: I use LabVIEW Base Development System 8.6.1 and Windows XP Pro on both computers.
I used the application builder from LabVIEW to create an executable file of my VI and an installer to install it on both computers. Of course I checked the two for ActiveX relevant checkboxes "Enable ActiveX Server" in the "Advanced" tab in the executable build and the "Register COM" in the "Source File Settings" in the installer build.
When I try to create a DCOM object in MATLAB, I get the following error:
>> lab2 =actxserver('Dummy.Application','192.168.0.2')
??? Error using ==> actxserver
Server Creation Failed: Access denied
Dummy.Application is the progID of my VI and 192.168.0.2 the IP of the server computer.
In the system log in the event viewer I get
Event ID: 10006.
Description: DCOM got error "General access denied error " from the computer 192.168.0.2 when attempting to activate the server {82417BDE-2542-41FE-A2D7-A372EBA55A60}
where {82417BDE-2542-41FE-A2D7-A372EBA55A60} is the application ID of my VI.
Interestingly enough I manage to start other programs on the other computer such as the internet explore, but it doesn't work with my VI, although I use exactly the same settings in the DCOM configuration in the system administration (Start->Execute "dcomcnfg". So I think it is a problem of LabVIEW, i.e. my VI, and not a problem of the DCOM settings of the two computers. What is confusing me is, that I manage to start the VI via ActiveX on the same computer, i.e. the computer with MATLAB.
Any advice would be highly appreciated. Thank you.

First of all, let's get your terminology correct. You are not creating multiple instances of a class. You are creating Objects of the class.
Use autoindexing to create an array of your class type.

Hi,
The maximum length supported by one CHAR type infoobject is 60. Check whether you have assigned more.
If you have to load more length ( more than 60) split the total thing into different infoobjects. Create different infoobjects and split the total thing into them - like 1st 60 char in 1st infoobject, char 61-120 in 2nd infoobject and so on. Then you can again concatenate them.

What is the diffrence between extends and creating new object?

HI ALL,
what is the diffrence between extends and creating new object?
meaning
class base{
class derived extends base{
class base{
class derived {
derived(){
base var = new base();
can u people tell me diffence from the above examples.
THANKS.
ANANDA

When you create a new object you have to supply the class to which that
object belongs. A class can extend from another class. If it does so
explicitly you can define the 'parent' class from which the class extends.
If you don't explicitly mention anything, the class will implicitly extend
from the absolute base class named 'Object'.
Your example is a bit convoluted: when you create a Derived object,
its constructor creates another object, i.e. an object from the class from
which the Derived class extends.
Extending from a class and creating an object don't have much in common.
kind regards,

Ho do we use Activity object of a Service Request object. I am trying to
create an Activity object for a existing Service Request object.
I am looking for some sample code.
I greatly appreciate your help.

drangineni, assuming you know the service requestid or externalId of the
Sr you are dealin gwith you would first set that value.
ServiceRequest1[] objSRList =new ServiceRequest1[1];
objSRList[0] = new ServiceRequest1();
objSRList[0].ServiceRequestId = <YourSRId>;
Then you create an array of activities and initialize the first one:
objSRList[0].ListOfActivity = new Activity[1];
objSRList[0].ListOfActivity[0] = new Activity();
Now set the data fields
objSRList[0].ListOfActivity[0].Subject ="My Subject";
objSRList[0].ListOfActivity[0].Description ="My Description";
objSRList[0].ListOfActivity[0].Display = "Task"; //valid values are either
"Task" or "Appointment"
Then call the ServiceREquestInsertOrUpdate method on the ServiceRequest
WebService and pass in the above variable.

Ah yes, I forgot you also need to specify a unquie Id for the activity.
It's kinda strange.
Try adding this:
ServiceRequest[0].ListOfActivity[ActivityLength].ActivityId = "DummyId";
//OD will overwrite this with a real Id
Or if you have a unquie ID for your Activities you can use:
ServiceRequest[0].ListOfActivity[ActivityLength].ExternalSystemId = <Your
Unique Value>;
Hope that helps,

Hi all,
I have a similar problem, but mine is returning a message that field
"Display" is required. Looking at this post and the documentation it is
obvious that Display is a required field, but my WSDL did not include a
field called "Display", so my proxy did not generate one.
I tried adding a field called Display to the WSDL and the proxy class, but
I get a different error... I figure I maybe cannot add it manually like
that - but I think the bigger problem is it is not part of the WSDL that
Siebel OD generates for me in my admin account.
On top of that Display is not shown in the list of fields for Activity
through the admin interface.. is it possible my account is bugged? Am I
missing something simple here? BigSlick, I see you mention a .Display in
your code sample so I thought you might understand what is wrong. Here is
my code (I am trying to add a activity to a lead).
Thanks for any insight into this!
private void InsertLeadActivity(Session session, NameValueCollection data,
string leadID)
try
if (blnDebug)
Response.Write("Setting up Activity ";
// instantiate the proxy service
Activity_Service.Activity activityProxy = new Activity_Service.Activity();
// set up the target URL
activityProxy.Url = session.GetURL();
activityProxy.CookieContainer = session.GetCookieContainer();
// set up input argument
ActivityNWS_Activity_Insert_Input input = new
ActivityNWS_Activity_Insert_Input();
input.ListOfActivity = new Activity1[1];
input.ListOfActivity[0] = new Activity1();
if (blnDebug)
Response.Write("Getting Data ";
// dg note: name value
// input.ListOfActivity[0].MrMrs = data["MrMrs"];
input.ListOfActivity[0].LeadId = leadID.ToString();
input.ListOfActivity[0].Description = DataToString(data);
input.ListOfActivity[0].Subject = "Website Submission Activity";
input.ListOfActivity[0].Priority = "3-Low";
//input.ListOfActivity[0].DueDate =
DateTime.Now.AddDays(7).ToShortDateString();
input.ListOfActivity[0].Owner = this.defaultLeadOwner;
input.ListOfActivity[0].Type = "Call";
//input.ListOfActivity[0].Display = "Task";
input.ListOfActivity[0].ActivityId = "DummyId";
input.ListOfActivity[0].ExternalSystemId = "web";
activityProxy.Activity_Insert(input);
catch (Exception exInsertActivity1)
if (blnDebug)
Response.Write(" Error inserting activity. " +
exInsertActivity1.ToString() + " ";

Figured it out.. the field "Display" is also known as "Activity"........
Here are some notes for other people.. good luck and feel free to write me
at raskawa-at-gmail-com if you want a code sample.
Some unpublished nice to knows for Siebel On Demand Activities....
In summary:
- .Activity is also known as Display in documentation and on the error
messages coming back from the WS. Also, it appears based on these boards
some people actually have a .Display field. Maybe different accounts
generate different WSDL's.... buggy.
- If a error message is thrown saying "Description is required" it really
means "Subject is required" (make sure .Subject has a value)
- If a error message is thrown complaining that ActionType is not right..
that is really .Type.. make sure it's lookup value is valid for the
dropdown values in your CRM OD system.
My code/values that worked..
input.ListOfActivity[0].LeadId = leadID.ToString();
input.ListOfActivity[0].Description = DataToString(data);
input.ListOfActivity[0].Subject = "Website Submission Activity";
input.ListOfActivity[0].Priority = "3-Low";
//input.ListOfActivity[0].DueDate =
DateTime.Now.AddDays(7).ToShortDateString();
input.ListOfActivity[0].Owner = this.defaultLeadOwner;
input.ListOfActivity[0].Type = "Call";
input.ListOfActivity[0].ActivityId = "DummyId";
input.ListOfActivity[0].ExternalSystemId = "web";
//input.ListOfActivity[0].Display = "Task"; //doesn't work
input.ListOfActivity[0].Activity = "Task"; //does work.

Hi,
This is surgientweb (under my own login now..)
Anyway, I wanted to add that I figured out that there are two ways to add
a Activity to a Lead. Via the Lead object (by getting a ListOfActivities)
OR by creating a Activity directly and just adding your "LeadID" to it (or
you can also add a "ContactID" to relate the activity to a Contact.)
Feel free to email me for a code example (raskawa....at....gmail)

Hi Stephane,
You can definitely read the categories using Tables in CRM. The logic is a bit complicated though.
Use the following steps to retrieve Categories using Std. CRM Tables:
1. Pass transaction GUID in field GUID of table CRMV_REPORT_SUBJ and get KATALOGART, CODEGRUPPE and CODE field values in lv_catalog, lv_codegrp and lv_code.
2. Now you need to concatenate these 3 fields values carefully like this:
CONCATENATE lv_catelog lv_codegrp ' ' lv_code into lv_category1.
Remember there are 4 spaces between lv_codegrp and lv_code.
3. Now pass this lv_category1 in field OBJEXT in table CRMC_ERMS_CAT_OK and get OBJGUID in field lv_objguid.
4. Pass this lv_objguid in field OBJ_GUID and LNK_TYPE = 'IS_CODE' in table CRMC_ERMS_CAT_LN and get value of CAT_GUID in lv_cat_guid.
5. Pass this lv_cat_guid in field CAT_GUID in table CRMC_ERMS_CAT_CA and get value of CAT_ID in field lv_cat_text.
Remember this lv_cat_text is the text value of your last level of category of transaction.
6. To get its upper cateogry level value, simply use table CRMC_ERMS_CAT_HI and get parent guid value and pass this as CAT_GUID again in table CRMC_ERMS_CAT_CA to get its text.
Alternatively, you can also use class method cl_crm_ml_category_util=>get_parse_all to get all levels of categories.
Hope this helps.
Thanks

When I try to open an embedded PDF file I get an error "The program used to create this object is AcroExch.exe.

When I try to open an embedded PDF file (Word doc) I get an error "The program used to create this object is AcroExch.exe. That program is either not installed on your computer, or is corrupt..." I've tried about everything from unchecking
protected mode at startup to removing & reinstalling Adobe. Nothing seems to fix this issue. Any other ideas?
This is happening on Adobe reader 9, 10 & 11 with MS Word 2010 & 2013. I've uninstalled, cleaned & reinstalled Reader 9, 10 & 11, as well as Acrobat 10 Pro & 11 Standard. Removed "Protected mode at startup, and changed
the default program for viewing from reader to Acrobat. This will not go away. It is affecting production at our company.

" Help > Troubleshooting Information > Profile Directory: Open Containing Folder" . i can't find open containing folder in profile directory. it does give me the option to open the places.sqlite file using graphic converter. when i try that, graphic converter gives me a window saying that it can't be opened because it is corrupted or is not a file type supported by graphic converter.
i appreciate your help with a workaround to get the old bookmarks. that works. however, the problem has morphed from that concern to why adobe reader [the default app.] won't open firefox .sqlite files. is the problem in adobe reader or firefox? also, how can i tell if the places.sqlite file is corrupt?
i'm getting in over my head here and do appreciate your help.

How to create multiple objects within a class

I have a item.lvclass which has an item.ctl (contains a cluster of class private data). I need to add another object (item2.ctl) within that same class so that I can reuse the code for that class.
So how do you create additional objects within the same class?

Well... right now... I've cornered myself going down this path: http://forums.ni.com/t5/LabVIEW-Idea-Exchange/LVOOP-Interfaces/idc-p/1314637#M8918
Seems like the solution in the idea was not implemented yet....
Okay. I will try to describe the situation differently...
Let's say I have a Car.lvclass
I want to have two objects: sedan & roadster
both have similar properties, but also have different properties:
4 doors vs 2 doors
hardtop vs convertible
silver vs white (color)
I want the two objects to be of the same class so that they can share the same private and public VI's. As a matter of fact, I want to have both objects in the VI's within the Car.lvclass.

How do I create multiple objects during runtime?

I don't know how to create multiple objects during runtime, here's my problem:
I get a String as input. Then I create an object called newobject. I put the object in a hashtable with the above string as key.
Then comes the problem, in order to create a new object, I have to rerun the same class, which uses the same name (newobject) to create a 2nd object. Now my hashtable doesn't reference to my 1st object anymore...
Is there anyway I can fill up the hashtable with different objects, and make each key point to each object it was supposed to?
For those who want to see a bit of the program:
public class PlayBalloon{
public Hashtable ht = new Hashtable();
for(){
Balloon pB = newBalloon;
newBalloon=new Balloon(pB);
ht.put("Some input from user", newBalloon);
for(){
ht.get(s).draw;<= s=string, draw=own meth. in Balloon
}

I think i can see the problem that you are having. You have, in effect, duplicate keys in your hashtable - ie, two strings used as keys with the same name.
The way that a hashtable works is as follows...
When you ask for a value that is mapped to a key it will go through the table and return the first occurence it finds of the key you asked for. It does this by using the equals() method of whatever object the key is (in your case it is a String).
If you cant use different Strings for your keys in your hashtable then i would consider writing an ObjectNameKey class which contains the String value that you are trying to put in the hashtable and an occurrence number/index or something to make it unique. Remember to override the equals method in your ObjectNameKey object or else the hash lookup will not work. For example
class ObjectNameKey {
 private String name;
 private int occurence;
 public ObjectNameKey(String name, int occ) {
 this.name = name;
 this.occurence = occ;
 public String getName() {
 return name;
 public String getOccur() {
 return occurence;
 public boolean equals(Object o) {
 if (!(o instanceof ObjectNameKey)) {
 return false;
 ObjectNameKey onk = (ObjectNameKey)o;
 if (onk.getName().equals(name) && onk.getOccur() == occurence) return true;
 return false;

Can you create an object from a string

I have been working on creating a dynamic form, creating the
form items from an xml file. I am getting very close to conquering
this task. I will share it when it's complete.
However, I am stuck at the moment trying to create an object
from a string. For example, if the xml item is an HBox I want to
create an HBox. Like this: parentObject = new arrayOfFormItems[
index ]..type ()
This isn't working. First, is this possible using some syntax
I am unaware of in Flex? I don't want to use a large if or case
statement if possible.
Thanks in advance for your help!

Thank you very much. Indeed that did solve the one problem. I
missed the casting as a Display Object. That is awesome!
I do still however, have to instantiate one of every item I
want to dynamically create or I get the following error when I try
to create a dynamic object that I have not instantiated before.
ReferenceError: Error #1065: Variable HBox is not defined.

at
flash.events::EventDispatcher/flash.events:EventDispatcher::dispatchEventFunction()
at flash.events::EventDispatcher/dispatchEvent()
at flash.net::URLLoader/flash.net:URLLoader::onComplete()
I read that you have no choice but to instantiate one of each
type to force the linker to link the code for that class into the
.swf. Unless you know another way to force it.
This is what I have in my Application mxml to get it to work:
<mx:HBox>
<mx:Text visible="false"/>
<mx:TextArea visible="false"/>
<mx:TextInput visible="false"/>
<mx:DateField visible="false"/>
</mx:HBox>
And those are the types I'm using to test with. . . I will
have to add all the others I want to use as well . . .

How can I create a object for a note?

Hi experts,
I need to apply the note 501905 but when I try in the SNOTE transacction I receive this error:
Object REPS Z_MRM_DELETE_PP does not exist; create it
Diagnosis
The SAP Note that you want to implement contains changes to an object that does not yet exist in your system.
SAP Notes contain only changes to objects that already exist. This means that the the system cannot automatically create new objects during the implementation of this SAP Note.
Procedure
1. Cancel the SAP Note implementationl.
2. Create an empty object REPS Z_MRM_DELETE_PP with the corresponding object editor.
3. Restart the SAP Note implementation.
How can I create that Object??
Thanks for the help!

Hi Carlos,
It says that you have to create a new program with a name Z_MRM_DELETE_PP.
Once you create and activate the program you can execute the SAP Note.
All this processure will be written in the SAP Note.
Please Go through the Note using below:
Step1: Use T.code SNOTE.
Step2: Use menu GOTO --> NOTE BROWSER. Provide the Note no and EXECUTE.
Step3: Double click on the displayed line.
Here you will get the information to do before implementing the note.
Go through all the documentation, and once you did all the development given in the note then you can implement the note.

Creating remote objects and passing the retrieved data to modules

I found at this Adobe tutorial a nice "RemoteService" class that creates a RemoteObject and contains the functions for handling the result and fault events. If I wanted to use this approach, how could I pass the data from the result handler to interfaces that modules from the main application could use?
I could put the RemoteService/RemoteObject in the modules, but (in my opinion- and I could be wrong) the best design seems to be using the remote calls in the main app and passing the data along to the modules.
Ultimately, I would like to know what the "best practices" are for creating remote objects and passing the retrieved data to modules
Thanks!

public void mouseClicked(MouseEvent e) {
X x = new X(e.getX(), e.getY());
}I don't see the difficulty.

Error while creating DiscoveryClient object

Hi,
i have an issue creating DiscoveryClient object. I tried to solve this by granting all permissions and THEN generating the secret but i still the same Exception.
public string discoveryId = "https://api.office.com/discovery/";
public string cmmAth = "https://login.windows.net/Common";
public async Task<OutlookServicesClient> EnsureClientCreatedAsync()
try
string authority = cmmAth;
_authenticationContext = new AuthenticationContext(authority);
DiscoveryClient discoCli = new DiscoveryClient(async () => await GetTokenHelperAsync(_authenticationContext, discoveryId));
CapabilityDiscoveryResult discoResult = await discoCli.DiscoverCapabilityAsync("Calendar");
var outlookCli = new OutlookServicesClient(discoResult.ServiceEndpointUri, async () => await GetTokenHelperAsync(_authenticationContext, discoResult.ServiceResourceId));
return outlookCli;
catch (AdalException e)
MessageBox.Show(e.ToString());
if(_authenticationContext != null && _authenticationContext.TokenCache != null){
_authenticationContext.TokenCache.Clear();
return null;
public async Task<string> GetTokenHelperAsync(AuthenticationContext context, string resourceId)
string accessToken = null;
AuthenticationResult result = null;
ClientCredential cliCred = new ClientCredential("xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx", "yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy=");
result = await context.AcquireTokenAsync(resourceId, cliCred);
accessToken = result.AccessToken;
return accessToken;
and my AdalException is
AADSTS70001: Application with identifier xxxxx-xxxx-xxxx-xxx-xxxxx was not found in the directory api.office.com
thx for any Help

Hi,
What the application type did you develop with: Web Application or Windows Client Application?
To use Office 365 API in ASP.NET Web Application, I suggest you referencing the sample project
O365-ASPNETMVC-Start.
internal static async Task<OutlookServicesClient> EnsureOutlookServicesClientCreatedAsync(string capabilityName)
var signInUserId = ClaimsPrincipal.Current.FindFirst(ClaimTypes.NameIdentifier).Value;
var userObjectId = ClaimsPrincipal.Current.FindFirst("http://schemas.microsoft.com/identity/claims/objectidentifier").Value;
AuthenticationContext authContext = new AuthenticationContext(SettingsHelper.Authority, new ADALTokenCache(signInUserId));
try
DiscoveryClient discClient = new DiscoveryClient(SettingsHelper.DiscoveryServiceEndpointUri,
async () =>
var authResult = await authContext.AcquireTokenSilentAsync(SettingsHelper.DiscoveryServiceResourceId,
new ClientCredential(SettingsHelper.ClientId,
SettingsHelper.AppKey),
new UserIdentifier(userObjectId,
UserIdentifierType.UniqueId));
return authResult.AccessToken;
var dcr = await discClient.DiscoverCapabilityAsync(capabilityName);
return new OutlookServicesClient(dcr.ServiceEndpointUri,
async () =>
var authResult = await authContext.AcquireTokenSilentAsync(dcr.ServiceResourceId,
new ClientCredential(SettingsHelper.ClientId,
SettingsHelper.AppKey),
new UserIdentifier(userObjectId,
UserIdentifierType.UniqueId));
return authResult.AccessToken;
catch (AdalException exception)
//Handle token acquisition failure
if (exception.ErrorCode == AdalError.FailedToAcquireTokenSilently)
authContext.TokenCache.Clear();
throw exception;
return null;
For Windows client application, you could get the token by using the code as following:
private async void GetToken()
string authority = "https://login.windows.net/Common";
AuthenticationContext authenticationContext = new AuthenticationContext(authority);
string discoveryResourceId = "https://api.office.com/discovery/";
String clientId = "{Client ID}";
Uri redirectUri = new Uri("http://localhost/{return GUID}");
var token = authenticationContext.AcquireToken(discoveryResourceId, clientId, redirectUri);

Getting Error while creating Document object after parsing XML String

Hi All,
I have been trying to parse an XML string using the StringReader and InputSource interface but when I am trying to create Document Object using Parse() method getting error like
[Fatal Error] :2:6: The processing instruction target matching "[xX][mM][lL]" is not allowed.
seorg.xml.sax.SAXParseException: The processing instruction target matching "[xX][mM][lL]" is not allowed.
Please find the code below which i have been experimenting with:

          System.out.println("contents >> "+file);
          parseQuickLinksFileContent(file);
public static void parseQuickLinksFileContent(String fileContents) {
PWMQuickLinksModelVO objPWMQuickLinksModelVO = new PWMQuickLinksModelVO();
     try {
DocumentBuilderFactory factory =           DocumentBuilderFactory.newInstance();
     DocumentBuilder builder = factory.newDocumentBuilder();
     StringReader objRd = new StringReader(fileContents);
     InputSource objIs = new InputSource(objRd);
     Document document = builder.parse(objIs); // HERE I am getting Error.
     System.out.println(document.toString());
What is happening while I am using builder.parse() method ???
Thanks,
Rajendra.

Error in creating triangle object

I am getting an error message of " cannot resolve symbol"..when i tried to create an object for the triangle class.It points at the 'Triangle' class itself when the program is compiled.
I just hope that I have imported the right package.Can somebody help me with that.

OK, Triangle isn't a standard class.
Is it something you wrote, or is it something that was provided to you?
If it's something you wrote, you'll either need to compile it first, or compile it at the same time as what you're compiling now. If you already have compiled it, you may need to specify the classpath to include it.
If it was provided to you, you'll need to check the docs to see what its full package name is, and to include it in the classpath. Did it come as a class file or in a jar file?

Hi,
Please check the following settings in SPRO:
Plant Maintenance & Customer Service - -Master Data in Plant Maintenance & Customer Service --Technical Objects --Functional Locations --Alternate Labeling of Functional Locations - - Activate Alternative Labeling --
In this setting pls inactive the setting for Alt.Label.Then go to ES55 and try.It will work.
