c# - Retrieving Building Blocks from user generated Word document -

i've searched far , wide, , haven't found proper solution yet.

first off, winforms application using .net 4.0 , devexpress.

i've been attempting retrieve building blocks (watermarks, cover pages etc) word documents (.docx), or @ least user generated template files (.dotx), user uploads application, saved database.

i must able retrieve building blocks used in file.

i have tried lot of different ways of retrieving them, can retrieve them built-in building blocks.dotx file, located in:

c:\users\<username>\appdata\roaming\microsoft\document building blocks\1033\14\built-in building blocks.dotx 

i haven't figured out how extract them user generated file.

here work in progress code i've been using (many iterations can debug it):

private void savebuildingblock(string savedfile) {   try   {     microsoft.office.interop.word.applicationclass wordapplication = null;     wordapplication = new microsoft.office.interop.word.applicationclass();     microsoft.office.interop.word.document worddocument = wordapplication.documents.opennorepairdialog(savedfile);      object missing = system.type.missing;      database.toolbaritemswordinsertfiledata.filedata = filehandler.filebytelocked(savedfile);     database.toolbaritemswordinsertfiledata.id = 0;     database.toolbaritemswordinsertfiledata.toolbaritemid = toolbarid;     database.toolbaritemswordinsertfiledata.save();      listbuildingblocks(wordapplication, wordpage);   }   catch (exception err)   {     logger.log(err);   } } 

next method:

private void listbuildingblocks(microsoft.office.interop.word.application wordapplication, wordpages wordpage) {   microsoft.office.interop.word.wdbuildingblocktypes type = wordpage == wordpages.coverpage ? type = microsoft.office.interop.word.wdbuildingblocktypes.wdtypecoverpage : type = microsoft.office.interop.word.wdbuildingblocktypes.wdtypewatermarks;   (int = 1; <= wordapplication.templates.count; i++)   {     try     {       if (wordapplication.templates[i] != null)       {         microsoft.office.interop.word.categories categories = wordapplication.templates[i].buildingblocktypes.item(type).categories;         (int c = 1; c <= categories.count; c++)         {           try           {             //category cat = categories.application[0];             microsoft.office.interop.word.buildingblocks buildingblocks = wordapplication.templates[i].buildingblocktypes.item(type).categories.item(categories.item(c).name).buildingblocks;             (int b = 1; b <= buildingblocks.count; b++)             {               try               {                 microsoft.office.interop.word.buildingblock buildingblock = buildingblocks.item(b);                 if (buildingblock != null)                 {                   //saving database occurs here                 }               }               catch (exception err)               {                 messagebox.show(err.message);               }             }           }           catch (exception err)           {             messagebox.show(err.message);           }         }       }     }     catch (exception err)     {       messagebox.show(err.message);     }   } } 

the wordpages parameter [wordpage] used in application specify if it's watermark or cover page (it's property in user control).

you need add current list of add-ins, can open template working building blocks. apart changing attached template , loading way, don't see other way of doing this:

    dim app = globals.thisaddin.application      'load file containing building blocks     app.addins.add("\\path file.dotx")      'get object loaded template     dim template = app.templates(app.addins.count)      'go through each building block in file     = 1 template.buildingblockentries.count         dim bb = template.buildingblockentries.item(i)     next 

if need go down xml route, building blocks stored inside package in word\glossary\document.xml easier if doing server side wont need work word object model @ all, use open xml sdk, it's pretty useful things this!
