13. PRINTING DUPLICATE COPIES13.1 OverviewFor legal reasons, it may be useful to keep an identical copy of a report (an invoice for example).Furthermore, due to the large amount of data to process (statistical reports for example), some reports maytake quite a long time to generate.The Duplicate feature automatically proposes a solution to this problem.The principle is straightforward:When editing a report (created in the report editor or by programming), its identical copy can be generatedand stored in a file in ".dpl" format.This allows you to re-edit a duplicate copy of the report. The data is not processed again so it is protectedagainst the modifications and this re-edit operation is performed immediately.The creation of a duplicate copy can be performed:• from the print preview (WinDev only).•by programming.This duplicate copy can be signed or not.Notes:• Printing a report with duplicate copies slows the print down. Indeed, the duration for creating the duplicatecopy is included in the print duration. We advise you to run performances tests.•Printing a page of a report with duplicate copy triggers the creation of the duplicate copy for the entirereport.13.2 Creating a duplicate copy from the print preview(WinDev only)13.2.1 Print available by defaultThe print preview proposes a button allowing the user to create a duplicate copy of the report currently displayed.When this button is clicked, a file picker allows the user to:• enter the name of the duplicate file that will be created.• specify the certificate that will be used to sign the duplicate. The signature of the duplicate is optional.By default, the duplicate:• is saved in the directory of the application.• has no password.• is named: Dupli_YYYYMMDD_HHMMSS.dpl.Note: To modify these parameters, you can use iParameterDuplicate before displaying the print preview window.13.2.2 Customizing the created duplicate copyTo modify the default parameters for the duplicate copies created from the print preview, you have the abilityto use iParameterDuplicate associated with the iDplPrintout constant.130Part 1: Report editor
Example:// Configure the duplicate of the invoiceiParameterDuplicate(iDplPrintout, "C:\Temp", ..."MyDuplicate_%d_%h", "DDDD DD MMMM YYYY", "HH.MM.SS")// Print the duplicate copyiPreview()iPrintReport(RPT_Invoice_Report)iParameterDuplicate allows you to:• customize the options for duplicate copy proposed by default by the button.• automate the print of a duplicate copy from the print preview. Indeed:• the duplicate copy will be generated during the print (performed from the print preview).• if an annotation or an edit control is modified in the print preview, a new duplicate copy will be generatedduring the next print.• if the print is performed on several printers, a duplicate copy will be generated for each printer.Note: The list of duplicate files created during the last print is returned by iLastFile.13.3 Creating a duplicate copy by programmingTo create a duplicate copy by programming:1. Use iParameterDuplicate (associated with the iDplPrintout constant) to configure the options for creatingthe duplicate copies.2. Use iDestination and specify that the print must be performed on a printer. The duplicate copy will becreated during the print.To stop printing the duplicate copies, use iParameterDuplicate (associated with the iDplNone constant).13.4 Signing a duplicate copyThe duplicate copies can be signed via a certificate. This signature ensures the integrity of the reports stored.The signature is included in the duplicate.This signature automatically perform a date and time stamping. If may be required legally for some uses.The signature standard used is PKCS7.You have the ability to sign a duplicate copy via a certificate:• from the print preview (See "Creating a duplicate from the print preview" in this page.•by programming:• The signature of duplicate copies is performed via functions:iDestinationiParameterDuplicateConfigures the print destination of the reportConfigures the automatic creation of the duplicate copy generated during thenext print.• the signature of a duplicate file is checked by CertificateCheckDuplicate.Part 1: Report editor 131
