Sets a custom stream as the underlying stream for RawData

aStream |
|
The custom stream to use as the underlying RawData stream. It can be nil |
Normally, RawData uses a memory stream or the original resource stream (e.g. the original file containing the resource) as its underlying stream. This method allows the user to use a custom stream as the underlying stream. This can be useful when a resource must be created from the contents of an original file as-is.
If aStream is nil, a new memory stream is used as the underlying stream. This can be used to remove a previously set custom stream as the underlying stream.
Sample code
This code creates a resource containing an html file
var aType, aName : TResourceDesc; aRes : TGenericResource; aFile : TFileStream; begin aType:=TResourceDesc.Create(RT_HTML); aName:=TResourceDesc.Create('index'); aRes:=TGenericResource.Create(aType,aName); aFile:=TFileStream.Create('index.html',fmOpenRead or fmShareDenyNone); aRes.SetCustomRawDataStream(aFile); //do something... aRes.Free; aFile.Free; aType.Free; aName.Free; end;
