How to convert office files (docx, xlsx) to google format in c# -


anyone share way convert docx, xlsx, pptx google format in programmatic. uploading through google drive api , sharing users using c#. every time creating duplicate document when edit file.

i want convert file while upload. can share converted file everyone.

i using google drive v3 api.

download code:

private static system.io.memorystream downloadfile(driveservice service, string fileid)     {         var request = service.files.get(fileid);         var stream = new system.io.memorystream();          // add handler notified on progress changes.         // notify on each chunk download , when         // download completed or failed.         request.mediadownloader.progresschanged += (google.apis.download.idownloadprogress progress) =>         {             switch (progress.status)             {                 case google.apis.download.downloadstatus.downloading:                     {                         console.writeline(progress.bytesdownloaded);                         break;                     }                 case google.apis.download.downloadstatus.completed:                     {                         console.writeline("download complete.");                         //savestream(stream, saveto);                         break;                     }                 case google.apis.download.downloadstatus.failed:                     {                         console.writeline("download failed.");                         break;                     }             }         };         request.download(stream);         return stream;     }      private static void savestream(system.io.memorystream stream, string saveto)     {         using (system.io.filestream file = new system.io.filestream(saveto, system.io.filemode.create, system.io.fileaccess.write))         {             stream.writeto(file);         }     }

here's started friend. check basic uploads , importing google docs types shows how upload , convert file types google formats.

var filemetadata = new file() {     name = "my report",     mimetype = "application/vnd.google-apps.spreadsheet" }; filesresource.createmediaupload request; using (var stream = new system.io.filestream("files/report.csv",                         system.io.filemode.open)) {     request = driveservice.files.create(         filemetadata, stream, "text/csv");     request.fields = "id";     request.upload(); } var file = request.responsebody; console.writeline("file id: " + file.id);

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
