Brief Information about the November 2005 CSIG Meeting

StringsW.exe - A Strings Display Program for Windows

3rd Tuesday of the month. 7:30PM - C/C++ Group, SPRS

Welcome to the C++ Users Group. This group is a "Special Interest Group" of the ACGNJ devoted to discussing programming languages in general and C, C++, and C++ for Windows programming in particular. Each month a small but hopefully useful program (complete with source code) is presented for discussion.

OBJECT ...

The object of this utility is to display the strings contained within any file. (A string is simply a group of characters.) The typical usage is for the recovery of information contained within damaged files that fail to open in their original applications. A word processor file, for example, will often contain most of the text of the document even if it can't be opened. Any discovered text can be copied using Ctrl-C and then pasted elsewhere. Use "Drag and Drop" from Windows Explorer to open any file.

C++ Language Elements

At the meeting on Tuesday night we will be discussing the utility and the source code.

Addendum - Bad Floppy Fix

I decided to see if I could copy all the sectors off the disk using "Sector Access" which I had downloaded from www.simtel.net (cool site). Here is the link for "Sector Access":

I used the string of sectors feature and copied every sector starting at "00000000". I entered "2847" for the number of sectors. A complete disk image went into a file I named, "DISK.IMG" without any errors!!! This file was then dropped into StringsW.exe to recover ALL of the text on the floppy via the clipboard. WoW.
