Hello,

I have an issue with the Compress-Function. When i want to compress a folder and in the folder path is a dot the function returns -13

(e.g. E:\temp\f.older_name\compress_test). The dot is not in the foldername that has to be compressed, it can be located anywhere in the path. Without the dot everything works fine. Is this a known problem or is there a solution for my Problem?

I am working with Powerbuilder 2021 Build 1506

 

Thank you for your help

Timo

 

integer li_rc
string ls_Foldername
string ls_Source

CompressorObject lnv_Compress

ls_Foldername = "C:\temp\f.older_name\compress_test"
ls_Source = "C:\temp\f.older_name\compress_test\"

lnv_Compress = create CompressorObject

li_rc = lnv_Compress.Compress(ls_Source, ls_Foldername, ArchiveFormatZip!) // returns -13

Sounds like a bug. You should open a bug report.

Hi,

What's in ls_folderName used for?

What's in ls_ExportPath? It should be a path with a filename I think.

regards

I think that your ls_filderName should not only be a path, but also include a filename.zip maybe?

Also, try setting the destination to a different folder as the origin. If not successful, create a Bug ticket as suggested by Mr. Ullrich.

Since you say it works when not dot is in the path, maybe, when you don't include the filename in the destination, powerbuilder assumes that the filename extension is whatever follows the lastpos() of the dot in your path. (would still be a bug maybe).

Hi Timo，

This is because there is a dot in the target directory, the Compress function will not append the file extension. Please report the issue via our standard support ticketing system to ensure it is being properly received and tracked by our tech support:
https://www.appeon.com/standardsupport/. Many thanks in advance.

In your case, it will create file 'compress_test' instead of 'compress_test.zip'. However, 'compress_test' conflicts with the existing folder name 'compress_test', so it failed to be compressed. Please try to work around the issue by specifying the file extension, for example:
ls_Foldername = "C:\temp\f.older_name\compress_test.zip"

Regards,
Kai
