Description

The UpdateZipDate method sets the date of the archive file to the most recent date among the files it contains.

Examples

 To update the "last modified date" of a zip file in regards to the most recent "last modified date" of the files that it contains:

Visual Basic

Copy Code

xErr = xZip.UpdateZipDate( xutUpdateLastModifiedDate + xutFromRespectiveDate + xutUseNewestDate ) ' Equivalent to: xErr = xZip.UpdateZipDate( xutUpdateLastModifiedDate + xutFromLastModifiedDate + xutUseNewestDate ) ' And to: xErr = xZip.UpdateZipDate( xutDefaultBehavior ) 'To update the "created date" of a zip file in regards to the oldest "created date" of the 'BMP files that it contains: xZip.FilesToProcess = "*.bmp" xErr = xZip.UpdateZipDate( xutUpdateCreatedDate + xutFromRespectiveDate + xutUseOldestDate ) ' Once again, xutFromCreatedData can be used instead of xutFromRespectiveDate ' Update all the dates of the zip file in regards to the current date: xErr = xZip.UpdateZipDate( xutUpdateAllDates + xutFromCurrentDate )

Method UpdateZipDate( xOptions As xcdUpdateZipDateOptions )                    

void XzUpdateZipDate( HXCEEDZIP hZip, xcdUpdateZipDateOptions xOptions )                    

Parameters

Return values

 If no file matches the specified filters, or a date is not specified, error 509  (xerNothingToDo) will be returned.

Remarks

• If xutFromCreatedDate, xutFromLastAccessedDate or xutFromRespectiveDate is used in combination with xutUpdateCreatedDate or xutUpdateLastAccessedDate, the zip file MUST use the "filetimes extra headers" otherwise this information is not available.

• All the filtering properties are applied when using the UpdateZipDate method. It is exactly like calling the ListZipContents method and only looking at the files that have the "bExcluded" parameter of the ListingFile event set to false. Other than the ListingFile event, all other events are the same.

• The UpdateZipDate method cannot be used on archive files created with the SpanMultipleDisks property set to True.
