The SetSourceNameValidation method specifies how the render engine validates file names.
Syntax
object.SetSourceNameValidation(
FilterString As String,
pOverride As MediaLocator,
Flags As Long
)
Parameters
FilterString
String containing pairs of filter strings formatted as required by the lpstrFilter member of the Microsoft® Win32® OPENFILENAME structure. The media locator uses this filter if it displays an Open dialog box.
pOverride
Optional MediaLocator object to use in place of the default. To use the default media locator, set the value of this parameter to NULL. See Remarks for more information.
Flags
Bitwise combination of flags taken from the File Name Validation Flags, specifying the behavior of the MediaLocator object. The SFN_VALIDATEF_CHECK flag must be present. The SFN_VALIDATEF_IGNOREMUTED flag has no effect with this method.
Error Codes
If the method fails, an error is raised, and Err.Number can be set to the following value:
| Value | Description |
| E_MUST_INIT_RENDERER | Render engine failed to initialize. |
Remarks
Using the pOverride parameter, you can supply your own custom implementation of the MediaLocator object.
Currently, this method does not validate dynamically loaded sources. See SetDynamicReconnectLevel.
