/ALLOWBIND (Prevent DLL Binding)


The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The latest version of this topic can be found at -ALLOWBIND (Prevent DLL Binding).


## Remarks  
 /ALLOWBIND:NO sets a bit in a DLL's header that indicates to Bind.exe that the image is not allowed to be bound. You may not want a DLL to be bound if it has been digitally signed (binding invalidates the signature).  
 You can edit an existing DLL for /ALLOWBIND functionality with the [/ALLOWBIND](../Topic/-ALLOWBIND.md) option of the EDITBIN utility.
