Recover API – New API in AutoCAD 2015

By Virupaksha Aithal

A long time request by developer community is to recover the drawing files through API. That request has been addressed in AutoCAD 2015. Now, document collection class has a new API “AppContextRecoverDocument” which takes the name of the drawing file to recover. This API is present in ObjectARX and in .NET. In ObjectARX use AcApDocManager::appContextRecoverDocument() API.

[CommandMethod("RecoverTest", CommandFlags.Session)] publicvoid RecoverTest() // This method can have any name {     Document doc =          Application.DocumentManager.MdiActiveDocument;     DocumentCollection docs = Application.DocumentManager;     Editor ed = doc.Editor;      OpenFileDialog file =          newOpenFileDialog("Select file to recover", null,                             "dwg;dxf", "Recover",            OpenFileDialog.OpenFileDialogFlags.DoNotTransferRemoteFiles);                   //show the dialog and take the dwg input     System.Windows.Forms.DialogResult dr =  file.ShowDialog();     if (dr != System.Windows.Forms.DialogResult.OK)            return;     try     {         //call  AppContextRecoverDocument to revover the selected DWG.         docs.AppContextRecoverDocument(file.Filename);     }     catch     {         ed.WriteMessage("Unable to recover the drawingn");     } }
