IMMComponent::Init
|
|
|
|
This function is called when the framework actually wants you to create your

display window and be ready to play back media.
|
|
|
|
If at all possible, you should delay loading anything that will increase your
|
|
memory footprint (i.e. support DLLs) until this call is made. That will allow
|
|
the framework to load much more quickly and only take the hit if the user actually
|
|
decides to use your component. Once the Init call is made, however, you will not
|
|
be asked to unload until this object's refcount is 0, which may or may not be when

the framework itself unloads.

|
component should be child windows of this one, so when the framework calls
|
|
show / hide on this main window, all of your childen will show / hide as well
|
|
This window should be created as a child of the "main" window sent into this
|
|
function, and it should be created without the WS_VISIBLE flag set.

IMMComponentAutomation::OnAction

|
|
|
If the component supports IMMComponentAutomation, it is able to respond to transport
|
|
control requests without having its UI pressed. This is handy to allow the user to
|
|
script the component via VBScript or JavaScript on a web page. The framework will
|
|
handle all of the necessary details; the component just needs to respond appropriately
|
|
to this method.
