I think iocreatefile should be called by the system. It will call the obcreateobject function. Both iocreatefile and iocreatedevice call the obcreateobject function. In iocreatefile, Status = obcreateobject

In order to better learn reactos, deliberately found a very early version, removed with SVN, http://svn.reactos.org/reactos/tags/ReactOS-0.0.10/ The Make version in the reactos compilation environment is a bit problematic. For example, calling

Reactos logs are disabled by default. In the system, select "reactos (Debug)". At this time, logs are output through the serial port. To print logs, you can use the dbuplint function. The ndebug macro controls the output log in the dbg version.

First, observe the MAKEFILE file in the reactos root directory. Include lib/lib. MakInclude tools/tools. Mak # Here are some pre-prepared tools such as rbuild-Include $ (ros_automake) # This file uses rbuild to generate the makefile. Auto File

ListBox control vs ComboBox Multiple lines can be selected for ListBox. ComboBox is similar to the combination of ListBox and edit, saving the size compared with ComboBox. ComboBox can be set to three States: simple (similar to ListBox at this

Your new class can be made up of any number and type of other objects, in any combination that you need to achieve the functionality desired in your new class. because you are composing a new class from existing classes, this concept is called

Obinit is called twice. When the values of obpinitializationphase are true and false. When obpinitializationphase = ture, create the root directory \ and \ objecttypesWhen obpinitializationphase = false, call obcreateobjecttype to create type,

The dual interface is an excuse for this class to implement the idispatch interface and self-implemented ixxxx. At the same time, let ixxxx inherit from the idispatch interface. This ensures that the ixxxx interface is compatible with idispatch.

Begin_msg_map macro generates a class function, which is called by window functions. When debugging, you will find that when the message comes, the debugger will track between begin_msg_map and end_msg_map. Another macro is better. It is

Symmetric algorithms use the same key for encryption and decryption. The advantage is that they are fast, but the disadvantage is that they are difficult to manage and are easy to leak. Asymmetric keys are also called Session keys. Asymmetric
