First one is using of SharePoint Services RPC Methods:
1. Create query in XML format to call NewWebPage method:
<?xml version="1.0" encoding="UTF-8"?>
<Batch>
<Method>
<SetList Scope="Request">DocLib_ID</SetList>
<SetVar Name="ID">New</SetVar>
<SetVar Name="Cmd">NewWebPage</SetVar>
<SetVar Name="Type">BasicPage|WebPartPage</SetVar>
<SetVar Name="WebPartPageTemplate">LayoutID</SetVar>
<SetVar Name="Title">AspxTitle</SetVar>
<SetVar Name="Overwrite">true</SetVar>
</Method>
</Batch>
Where:
- DocLib_ID is ID (GUID) of document library where do you need to create new aspx file.
- BasicPage|WebPartPage type of aspx. Use BasicPage for page without layout (LayoutID =0) and WebPartPage for all other terms
- LayoutID specifies page layout [1...8]
2. Call SPWeb.ProcessBatchData method with this query.
3. If you need to create aspx file in document library subfolder, create it in doclib and move to the necessary subfolder with SPFile.MoveTo method.
But this approach doesn't work for meeting workspace where you can create several pages with access via convenient multi-page web part.
To create new pages there you need to use SPMeeting.AddPage (AspxTitle, InstanceID, out resNewPageUrl) method. Set InstanceID = 0 to create page directly in the Workspace Pages library.
