mierlp Posted December 27, 2012 Share Posted December 27, 2012 Hi, Within my application i have a form which contains a listbox with all tables. The user can select a table he wants to export. When he hits the export button the following code will be executed: // Database if NOT dmArtist.Artist.Active then dmArtist.Artist.Active:=TRUE; // Excel export scExcelExport.DataSet:=dmArtist.Artist; scExcelExport.WorksheetName:='Artiesten'; scExcelExport.HeaderText.text:='Artiesten per ' +DateToStr(Date) ; scExcelExport.ExcelVisible:=false; try scExcelExport.ExportDataset; ExportFile:='Artiesten per ' +FormatDateTime('hhmmss', Time) ; scExcelExport.SaveAs(UniServerModule.FilesFolderPath+ExportFile,ffXLS) finally scExcelExport.Disconnect; // Save export UniSession.SendFile(UniServerModule.FilesFolderPath+ExportFile+'.xls', 'Artiesten.xls'); end; end; I save the file to UniServerModule.FilesFolderPath and every file will be created. Sometimes after 3 or 5 export actions (files are created) i got the followin message : 'Cannot open file C:\Data\Delphi\UniGui\myEventWeb\cache\Artiesten per 133412.xls' The process has no access to the file because it's used by a other proces See attachement...it's in Dutch but the translation is above. I test i local as you can see by the path names. Regards Peter Quote Link to comment Share on other sites More sharing options...

Administrators Farshad Mohajeri Posted December 31, 2012 Administrators Share Posted December 31, 2012 It seems that XLS file is still in use. In next build I will modify code so you can send it even if file is still in use. Quote Link to comment Share on other sites More sharing options...

mmurgas Posted April 27, 2013 Share Posted April 27, 2013 for me this code is correct, but I broke my head trying to export my data // Database if NOT dmArtist.Artist.Active then dmArtist.Artist.Active:=TRUE; // Excel export scExcelExport.DataSet:=dmArtist.Artist; scExcelExport.WorksheetName:='Artiesten'; scExcelExport.HeaderText.text:='Artiesten per ' +DateToStr(Date) ; scExcelExport.ExcelVisible:=false; try scExcelExport.ExportDataset; ExportFile:='Artiesten per ' +FormatDateTime('hhmmss', Time) ; scExcelExport.SaveAs(UniServerModule.FilesFolderPath+ExportFile,ffXLS) finally scExcelExport.Disconnect; // Save export UniSession.SendFile(UniServerModule.FilesFolderPath+ExportFile+'.xls', 'Artiesten.xls'); end; end; Quote Link to comment Share on other sites More sharing options...

mmurgas Posted May 15, 2013 Share Posted May 15, 2013 Thanks Farshad finally perform the export as a file natively. CSV and it worked perfect.
