Predefined Protocols

Microsoft® Internet Explorer 4.0 implements various protocols that can be used to identify certain information. This document describes the protocols that Internet Explorer 4.0 implements or supports.
res:

The res: protocol specifies a resource that will be obtained from a module. This protocol takes the following format:
"res://resource file[/resource type]/resource id"
The following list describes each element:

resource file Required. Specifies the path and file name of the module that contains the resource.

resource type Optional. Specifies the string or numerical resource type. This can be either a custom resource type or one of the RT_ pre-defined resource types described in FindResource and defined in WINUSER.H. If a numerical resource type is being specified, the actual number of the identifier, not the identifier itself, must follow a '#' character. See the example below for more information. If this parameter is not specified, the default resource type is RT_HTML.

resource id Required. Specifies the string or numerical identifier of the resource. If a numerical identifier is being specified, the actual number of the identifier, not the identifier itself, must follow a '#' character. See the example below for more information.

The following example shows the correct and incorrect way to format the numerical identifier for the resource type:
//winuser.h defines RT_BITMAP
#include <winuser.h>

//this is correct
"res://mydll.dll/#2/MYBITMAP"

//this is not correct
"res://mydll.dll/RT_BITMAP/MYBITMAP"
The following example shows the correct and incorrect way to format the numerical identifier for the resource identifier:
#define MYBITMAP 234

//this is correct
"res://mydll.dll/#2/#234"

//this is not correct
"res://mydll.dll/#2/MYBITMAP"
