Wrong file name received by my application

[Wim S]

Hello,

When a file with the extension *.log_c is double-clicked, it is automatically opened by my application (I acheived this by adding some registry values). The pathname of the opened file is then received in the variable argv[1] of the main function of my application. However, on most systems it seems that the string I receive is not the same of the pathname, but some abbreviation that reminds me of DOS, where a file name or a directory could only be 8 characters, and a file extension could only be 3.

E.g: when I open the file C:\Documents and Settings\Wim\My Documents\LabWindows\DebugLogDecoder\dbg_20060621_114839.log_c, the string that I receive is C:\DOCUME~1\Wim\MYDOCU~1\LABWIN~1\DEBUGL~1\DBG_20~1.LOG

This problem occurs on some machines. On other machines argv[1] contains the correct pathname.

Why is that and how can I solve this problem?

Thanks for all help,

Wim

Wim, the reason why on some system the long file is passed to the program and on some others the short one will probably reside in some non-evident option of Windows that I don't know at present.

However, GetLongPathName windows API should help you to retrieve the long file name associated to the received command-line parameter.
