How to obtain all UniverseFolders and Connections using Designer COM SDK with C++

Hi,

I couldn't find a separate space for the COM SDK but I think this space is really similar and should get my problem fixed as well.

I recently started with the COM SDK and wanted to iterate over all the available folder and connections.

My current approach looks like this (I'm writing in C++):

// init & logon to the application works fine... 
// printer function is just printing to cout  
IApplicationPtr application..... 
IConnectionsPtr connectionsPtr = application->GetConnections(); 
printer(connectionsPtr->GetCount()); // prints 4
for(int i = 0; i<= connectionsPtr->GetCount(); i++){ 
     try{  
          IConnectionPtr connectionPointer = connectionsPtr.->Get_Item(i); 
          printer(connectionPointer->Name);
     } catch (const _com_error& e){ 
          // printException.... 
     }
}
// and the same for UniverseFolders 
IUniverseFoldersPtr folders = application->GetUniverseRootFolder()->GetFolders();
 printer(folders->GetCount()); // prints 3 
for(int i = 0; i<=folders->GetCount(); i++){
     try{
          IUniverseFolderPtr folderPointer = folders->Get_Item(i); 
          printer(folderPointer->Name); 
      } catch (const _com_error& e){ 
          // printException.... 
     }
}

The communication with the COM SDK seems to work because I can get the right count of folders and connections.

However as soon as I try to get the items I'll get a _com_error. I have tried with GetItem(i),Get_Item(i), Items[i].

The really strange what comes on top is for the connections I'll receive a com error telling me that there is no connection (No connection Found).

As soon I'll query the folders I'll receive a com error telling me that the parameter do not match (Invalid parameter: Index must be an integer or a string).

Also assume I have a connection called "shared" when I try to call GetItem("shared") everything works fine and I'll get the connection I want.

However I don't know the connection names.

I already could figure out that I could the folder or connection names by using the BI Query Builder and execute some fancy queries.

In case this is the only solution: How could I utilize the COM SDK (or any other SDK) to execute a query?

Any help on this really strange glitch is highly appreciated.

Thanks,

S
