# helpstringcontext
Specifies the ID of a help topic in an .hlp or .chm file.  
  
## Syntax  
  
```  
  
      [ helpstringcontext(  
   contextID  
) ]  
```  
  
#### Parameters  
 `contextID`  
 A 32-bit Help context identifier in the Help file.  
  
## Remarks  
 The **helpstringcontext** C++ attribute has the same functionality as the [helpstringcontext](http://msdn.microsoft.com/library/windows/desktop/aa366858) ODL attribute.  
  
## Example  
  
```  
// cpp_attr_ref_helpstringcontext.cpp  
// compile with: /LD  
#include <unknwn.h>  
[module(name="MyLib")];  
  
[   object,   
   helpstring("help string"),   
   helpstringcontext(1),   
   uuid="11111111-1111-1111-1111-111111111111"  
]  
__interface IMyI   
{  
   HRESULT xx();  
};  
```
