Registry Macros
These macros define useful type library and registry facilities.
| Name | Description |
|---|---|
| _ATL_STATIC_REGISTRY | Indicates that you want the registration code for your object to be in the object to avoid a dependency on ATL.DLL. |
| DECLARE_LIBID | Provides a way for ATL to obtain the libid of the type library. |
| DECLARE_NO_REGISTRY | Avoids default ATL registration. |
| DECLARE_REGISTRY | Enters or removes the main object's entry in the system registry. |
| DECLARE_REGISTRY_APPID_RESOURCEID | Specifies the information required to automatically register the appid. |
| DECLARE_REGISTRY_RESOURCE | Finds the named resource and runs the registry script within it. |
| DECLARE_REGISTRY_RESOURCEID | Finds the resource identified by an ID number and runs the registry script within it. |
Requirements
Header: atlcom.h
_ATL_STATIC_REGISTRY
A symbol that indicates you want the registration code for your object to be in the object to avoid a dependency on ATL.DLL.
#define _ATL_STATIC_REGISTRY
Remarks
When you define ATL_STATIC_REGISTRY, you should use the following code:
#ifdef _ATL_STATIC_REGISTRY
#include <statreg.h>
#endif
DECLARE_LIBID
Provides a way for ATL to obtain the libid of the type library.
DECLARE_LIBID( libid )
Parameters
libid
The GUID of the type library.
Remarks
Use DECLARE_LIBID in a CAtlModuleT-derived class.
Example
Non-attributed wizard-generated ATL projects will have a sample of using this macro.
DECLARE_NO_REGISTRY
Use DECLARE_NO_REGISTRY if you want to avoid any default ATL registration for the class in which this macro appears.
DECLARE_NO_REGISTRY()
DECLARE_REGISTRY
Enters the standard class registration into the system registry or removes it from the system registry.
DECLARE_REGISTRY(
class,
pid,
vpid,
nid,
flags )
Parameters
class
[in] Included for backward compatibility.
pid
[in] An LPCTSTR that is a version-specific program identifier.
vpid
[in] An LPCTSTR that is a version-independent program identifier.
nid
[in] A UINT that is an index of the resource string in the registry to use as the description of the program.
flags
[in] A DWORD containing the program's threading model in the registry. Must be one of the following values: THREADFLAGS_APARTMENT, THREADFLAGS_BOTH, or AUTPRXFLAG.
Remarks
The standard registration consists of the CLSID, program ID, version-independent program ID, description string, and thread model.
When you create an object or control using the ATL Add Class Wizard, the wizard automatically implements script-based registry support and adds the DECLARE_REGISTRY_RESOURCEID macro to your files. If you do not want script-based registry support, you need to replace this macro with DECLARE_REGISTRY. DECLARE_REGISTRY only inserts the five basic keys described above into the registry. You must manually write code to insert other keys into the registry.
DECLARE_REGISTRY_APPID_RESOURCEID
Specifies the information required to automatically register the appid.
DECLARE_REGISTRY_APPID_RESOURCEID(
resid,
appid )
Parameters
resid
The resource id of the .rgs file that contains information about the appid.
appid
A GUID.
Remarks
Use DECLARE_REGISTRY_APPID_RESOURCEID in a CAtlModuleT-derived class.
Example
Classes added to ATL projects with the Add Class code wizard will have a sample of using this macro.
DECLARE_REGISTRY_RESOURCE
Gets the named resource containing the registry file and runs the script to either enter objects into the system registry or remove them from the system registry.
DECLARE_REGISTRY_RESOURCE( x )
Parameters
x
[in] String identifier of your resource.
Remarks
When you create an object or control using the ATL Project Wizard, the wizard will automatically implement script-based registry support and add the DECLARE_REGISTRY_RESOURCEID macro, which is similar to DECLARE_REGISTRY_RESOURCE, to your files.
You can statically link with the ATL Registry Component (Registrar) for optimized registry access. To statically link to the Registrar code, add the following line to your pch.h file (stdafx.h in Visual Studio 2017 and earlier):
#define _ATL_STATIC_REGISTRY
If you want ATL to substitute replacement values at run time, do not specify the DECLARE_REGISTRY_RESOURCE or DECLARE_REGISTRY_RESOURCEID macro. Instead, create an array of _ATL_REGMAP_ENTRIES structures, where each entry contains a variable placeholder paired with a value to replace the placeholder at run time. Then call CAtlModule::UpdateRegistryFromResourceD or CAtlModule::UpdateRegistryFromResourceS, passing the array. This adds all of the replacement values in the _ATL_REGMAP_ENTRIES structures to the Registrar's replacement map.
For more information about replaceable parameters and scripting, see the article The ATL Registry Component (Registrar).
DECLARE_REGISTRY_RESOURCEID
Same as DECLARE_REGISTRY_RESOURCE except that it uses a wizard-generated UINT to identify the resource, rather than a string name.
DECLARE_REGISTRY_RESOURCEID( x )
Parameters
x
[in] Wizard-generated identifier of your resource.
Remarks
When you create an object or control using the ATL Project Wizard, the wizard will automatically implement script-based registry support and add the DECLARE_REGISTRY_RESOURCEID macro to your files.
You can statically link with the ATL Registry Component (Registrar) for optimized registry access. To statically link to the Registrar code, add the following line to your stdafx.h file (pch.h in Visual Studio 2019 and later):
#define _ATL_STATIC_REGISTRY
If you want ATL to substitute replacement values at run time, do not specify the DECLARE_REGISTRY_RESOURCE or DECLARE_REGISTRY_RESOURCEID macro. Instead, create an array of _ATL_REGMAP_ENTRIES structures, where each entry contains a variable placeholder paired with a value to replace the placeholder at run time. Then call CAtlModule::UpdateRegistryFromResourceD or CAtlModule::UpdateRegistryFromResourceS, passing the array. This adds all of the replacement values in the _ATL_REGMAP_ENTRIES structures to the Registrar's replacement map.
