Description
Creates an instance of TResourceStream associated with a particular resource name and type.
Call Create to instantiate a TResourceStream, passing in parameters that identify the resource in a specified instance. TResourceStream finds the resource data and loads it into the Memory buffer for the TResourceStream.
The Instance parameter is the instance handle associated with the executable or shared library that contains the resource.
In the first constructor syntax, the ResName is the string associated with the resource in the .rc file that was compiled with the application. If the resource is associated with an integer ID rather than a string, use the string representation of the integer after a pound sign. Thus, for example, a resource with an integer identifier of 128 be identified by a ResName of #128.
Note: Specifying resources by ID requires less memory than specifying resources by name.
The ResType parameter is a string identifying the type of the resource. Applications can define their own resource types and identify them by name in the .rc file. In addition, there are a number of predefined resource types (which reflect Windows resource types). To identify a resource that is one of the predefined resource types, set ResType to the appropriate value from the following table:
