[Enterpriseservices] Using assembly to define how our components are registered in COM +

Organizer zheng yu @ ultrapower

Use the followingAssemblyDefine our components inCOM +In, where:

ApplicationnameAttribute is"COM +Directory"And"Component Service Management"TheCOM +ApplicationProgram.

[Assembly: applicationname ("mydll. Interface")]

DescriptionThe property is"COM +Directory"And"Component Service Management"ConsoleCOM +The application provides instructions.

[Assembly: Description ("My serviced component")]

ActivationoptionProperty indicates whether a component is activated in the caller's process. Here we willActivation. OptionSet to a server, that is, "The component will be activated in the dedicated server process ".

[Assembly: applicationactivation (activationoption. Server)]

ApplicationaccesscontrolSet the access management and verification level for the attribute. Here we set: Do not force access permission check for this application; The called authentication level is none; the simulated level is delegate.

[Assembly: applicationaccesscontrol (value =False,

Impersonationlevel = impersonationleveloption. Delegate,

Authentication = authenticationoption. None)]

CodeAfter the above definition is implemented, you can simply use

Regsvcs mydll. dll or register our COM + component through the following class definition. The call method is:

"String strcomplusdllfilepath = rootforumsdirectory + @" \ bin \ mydll. dll ";

Ultrapower. installclasslib. installclassregsvcs. Install (strcomplusdllfilepath );"

This saves a lot of trouble.

Namespace Ultrapower. installclasslib

{

Public   Class Installclassregsvcs

{

Public Installclassregsvcs ()

{

}


Install # Region Install

// --- Override the 'install' method.

Public   Static   Void Install ( String Strcomplusdllfilepath)

{

// --- Checkpoint

Trace. writeline ( String . Format ( " Register COM + component {0} " , Strcomplusdllfilepath ));



// --- Action

Process installprocess =   New Process ();

Processstartinfo installinfo =   New Processstartinfo ( " Regsvcs.exe " );

Installinfo. Arguments =   "   "   + Strcomplusdllfilepath;

Installinfo. windowstyle = Processwindowstyle. hidden;

Installprocess. startinfo = Installinfo;


// Run

Installprocess. Start ();

Installprocess. waitforexit ();



}

# Endregion


}

}
