How can I store in a MDI Application (MFC) much data in the Document (CDocument) class? There is no database or something. I've got a dialog where I can type in adresses. This adresses must be stored.
I hope you understand my question.
Sincerely
Your CDocument derived class should access and store the data needed by your app. It can do this with member variables (appropriate data structures) that you add or it can do it via a database if you want a database. For example, the MSDN sample named ENROLL shows a CDocument that manages the connection to a database.

I have embedded Teiid 12.3 in a Spring Boot application. I want to get into the metadata of my VDB in order to generate a diagram using graphviz-java. I assume that if I have a org.teiid.metadata.Table object, I can call getIncomingObjects() to get references to tables that table depends on. I just can't figure out how to navigate from the EmbeddedServer to the Table objects.
I looked into using the administration API available via EmbeddedServer.getAdmin(). From there, I can call getVDBs(), and from there I can navigate down to getModels(), but below that level there is only the model source via getSourceMetadataText(). I also tried subclassing EmbeddedServer to make getVDBRepository() public. I can call getVDBRepository()*.getModels(), but it returns the same Model objects only get me access to the source definition of the models, not the runtime metadata model.
I tried getVDBRepository().getSystemStore() and VDBRepository.getODBCStore(), but those MetadataStores are not for the VDB I have deployed.
I haven't found any examples by Google, Teeid JIRA, Teiid forum, or StackOverflow to help me.
Take look at [1] the getSchema method on Admin API, this method returns the string form of the metadata, however you can grab Schema object for object form. If you do not want that way, Teiid also exposes system catalog using many SYS tables, you can issue SQL queries to grab the metadata of schemas and schema items in a VDB. One for internal access, another is from external access.
BTW one of users created a dependency diagram tool that may be useful if you are trying to do something similar. See [2]. Let me know if you interested in pushing that further.

I am using Vb 2010 in designing my apps. I've connected my database with my application but I didn't use any code in the connection. I used Data source and Databinding property and when I save the data the database is always empty. Please help me with a solution.
Place a BindingNavigator component in your form and set it's binding source property to the same datasource of your other component.
I am writing a shoebox type application wherein a user enters data into a single window. I’ve configured the data model with Code Data. Apple’s documentation states that user data should be stored in a Library Directory, however the auto-generated code seems to make a directory in the Application Support directory where one, the documentation also states, “should never store user data.” Which is correct?
The other question I have is should I not create an instance of NSPersistentDocument in the applicationDidFinishLaunching method?
User-created data should be managed by the user: the user should decide where they are saved, etc.
Application-created data would indeed belong in the application support directory. If your application creates an NSPersistentDocument without user intervention, this would be the correct place to store it. For example, if you were using NSPersistentDocument to manage application data it would belong in a sandboxed directory such as NSApplicationSupportDirectory.
The File System Programming Guide goes into this in more detail.
How do I run/call/kickoff an external program (custom code) whenever certain attributes or objects are added or modified in OpenDJ’s database?
Here is my real world need. (Feel free to change my thought direction entirely).
Whenever a new email address gets created or changed in the OpenDJ database I want to initiate some java code that does some email verification/validation (send the “click here” link with a token to prove the user owns the email they just signed up with).
I know, I could use OpenIDM/AM to accomplish this but to take this a step further I need to validate other information and other credentials (custom) which users supply that are not supported by OpenIDM/AM suites.
Initiating/calling custom code upon ADD or MODIFY of specific objects and attributes is what I want and would like to know how to accomplish this. Preferably without having to scrape logs.
Please Help.

OpenDJ has a plugin interface where you can plug Java calls on Add or Modify. A sample of this kind of plugin is the attribute uniqueness which verifies that some attributes have a unique value in the directory.
The plugin interface javadoc can be found here : http://docs.forgerock.org/en/opendj/2.6.0/javadoc/org/opends/server/api/plugin/DirectoryServerPlugin.html
How would you suggest working with files that is stored on the note of a entity in Crm. Could you write a generic method that will enable you to access any type of file? Or would it be better to have a method for dealing with each type of file?
For example, we are going to be saving a mix of swf files and xml files on the entity, so would it make sense to have a method each for example:
GetXmlFilesOnAccount(accountid)
GetSwfFilesOnAccount(accountid)
When you upload an attachment to CRM the mimetype is also saved as part of the record information.
The following link contains a nice example of how to download the attachemt using a single method. http://crmscape.blogspot.com/2009/10/ms-crm-40-sending-attachments-to.html
The post is missing the actual query needed to retrieve the annotations but you can tell what columns are required from the method signature.
My suggestion using your methods:
* GetXmlFilesOnAccount(accountid)
* GetSwfFilesOnAccount(accountid)
Retrieve account activitypointers by regardingobjectid(in your case accountid guid)
Loop through returned activitypointers
Get attachments for each activitypointer (activitypointer.activityid = activitymimeattachment.activityid)
Store attachments (disk, etc)
You don't even need two methods. You can retrieve all attachment file types for a given note (annotation) with a single method.
Hope this helps.
I recently started an Open Source Project on CodePlex to accomplish exactly that. Feel free to check out the Project's Web Page at:

You can also view the source code under the "Source Code" tab of that same page.
