Parameter.ConnectFromProgID
v2.0
Creates a DataSource
object from a ProgID string and connects it to the parameter.
Note: This method uses output
arguments. C# and some scripting languages (such as JScript,
PerlScript and Python) don't support arguments passed by reference.
Normally for scripting you can get the output arguments via the
ISIVTCollection, but
this method already returns a value (C# cannot use this workaround
because it does not have access to the ISIVTCollection).
The only available workaround in this case is to create a VBScript
custom command which returns both the output arguments and the
return value in one array. For details, see What Happens when the Function Already
Returns a Value?.
DataSource Parameter.ConnectFromProgID( String in_ProgID, Object& out_pvPrevDataSource ); |
oDataSource = Parameter.ConnectFromProgID( ProgID, [PrevDataSource] ); |
Newly created DataSource object, such as a Shader or an ImageClip.
| Parameter | Type | Description |
|---|---|---|
| ProgID | String | The ProgID is a string name that can be used to look up a data source type. Data sources that support ProgIDs implement a ProgID property (for example, Shader.ProgID). |
| PrevDataSource | DataSource object (for example, Shader, ImageClip) | The previously connected data source if any. The method returns "Nothing" if there is no previously connected data source. |
