Summary

Creates a profile object and fills it with the data from the passed string.

Syntax

C++

public Leadtools.Multimedia.WMProfile LoadProfileByData(  
   string Profile 
)

Public Function LoadProfileByData( _ 
   ByVal Profile As String _ 
) As Leadtools.Multimedia.WMProfile

public: 
Leadtools.Multimedia.WMProfile^ LoadProfileByData(  
   String^ Profile 
)

Parameters

Profile
An XML-formatted string that contains the profile data to load.

Return Value

A WMProfile object filled with profile data

Remarks

Creates a profile object and fills it with the data from the passed string. The passed string is an XML-formatted string saved using the SaveProfile method. This method is used to manipulate custom profiles, while system profiles are accessed using the LoadProfileByID or LoadSystemProfile methods. For more information, refer to the Microsoft documentation for IWMProfileManager.LoadProfileByData.
