The caller knows how much data is to be returned so the caller has no need to ask for how much data is available. Therefore, it is acceptable for an implementation of this method to return an error if the `pbData` parameter is `NULL`.

The `.pdata` section of a compiland contains information about exception handling for functions. It appears in the [PE Format](/windows/win32/debug/pe-format) as the "Exception Table" within the "Optional Header Data Directories."

The first time you publish, create a username and password. These credentials are specific to WebDeploy deployment. Once they're created, you can't change them in Visual Studio, but you can reset them in IIS. See [Sites - Set Credentials dialog box](/previous-versions/windows/it-pro/windows-server-2012-R2-and-2012/hh831681(v=ws.11)#set-credentials-dialog-box).

For example, consider publishing to a package from Visual Studio, and then use *WebDeploy.exe* from a command line to deploy the package. With that method, you can use IIS Manager to configure authorized Windows users who can publish to the web server, and run *WebDeploy.exe* under that Windows user account. See [Installing and Configuring Web Deploy on IIS 8.0 or Later](/iis/install/installing-publishing-technologies/installing-and-configuring-web-deploy-on-iis-80-or-later). If you do use password credentials, be sure to use a strong password, secure the password from being leaked or shared, and properly manage password rotation according to a fixed schedule.
