FILESEARCH
Post by Michael Hutton on May 24^th, 2009, 04:30am

While pondering on PROFILER.... I have written a library which will open a dialogue box and perform a recursive file search for you. (The original FNfsearch() routine by RTR). When a specific file is found the WIN32_FIND_DATA structure for that file is sent to a PROC that the user has specified (see PROC_FileSearch(PROC_FileFound()) and PROC_FileFound() in FILESEARCH DEMO). This removes the neccesity of customising the FN_fsearch routine every time you need to do a file search. You only need to update the PROC_FileFound() procedure.

Try out the demo at:

http://tech.groups.yahoo.com/group/bb4w/files/%22Temp%20Folder%22/MDCH/FILESEARCH/FILESEARCH%20DEMO.bbc

making sure you have FILESEARCH in your @lib$ folder.

http://tech.groups.yahoo.com/group/bb4w/files/%22Temp%20Folder%22/MDCH/FILESEARCH/FILESEARCH.bbc

When using it remember the procedure you name when calling PROC_FileSearch must have a pair of parenthesis so:

PROC_FileSearch(PROC_FileFound()) is correct

whereas:

PROC_FileSearch(PROC_FileFound)

will cause an error.

The parameters passed are (index%, WIN32_FIND_DATA{}) so make sure your procedure (PROC_FileFound() in this case) receives two parameters.....

I've added to FILESEARCH :

1. You can fill a FILESEARCH_OPTIONS{} which will allow the programmer to do a user initiated file search (ie opens a dialog box) or a programmer initiate file search.

2. The WIN32_FIND_DATA{} is now converted to a BBCBASIC_FILE_DATA{} of my own design which makes it easier to extract the information you want. See the FILESEARCH DEMO (now a standalone version which should run straight from the website).

The advantage of using this library is that you can customise your search from within the PROC you name.
