# tlbid
**C++ Specific**  
  
 Allows for loading libraries other than the primary type library.  
  
## Syntax  
  
```  
tlbid(number)  
```  
  
#### Parameters  
 `number`  
 The number of the type library in `filename`.  
  
## Remarks  
 If multiple type libraries are built into a single DLL, it possible to load libraries other than the primary type library by using `tlbid`.  
  
 For example:  
  
```  
#import <MyResource.dll> tlbid(2)  
```  
  
 is equivalent to:  
  
```  
LoadTypeLib("MyResource.dll\\2");  
```
