File Read Application Synopsis
The File Read application allows you to look at the contents of any
type of file. It displays the contents in both hexadecimal and ASCII
(if the byte is an ASCII character otherwise a period). Using the
Find option you can search for a string fragment and change that
string information. If an application for example expects to find a
file on the C: drive and you moved it to the D: drive, the
application will fail to find the file it expects if the information
is hard coded in the executable. Using this application you can find
the string fragment in the executable and change it from C to D. The
application will not allow you to increase or decrease the size of
any file. You must match any changes character for character.
NOTE: You will not be allowed to save your modifications until you
have registered the application.
General
File Read remembers the last directory where a file was selected to
read and will default to that directory on the next read.
Additionally, File Read will save up to the last 30 search strings
and allow you to reuse those stings. For those of you who want a
constant start position on your desktop, File Read remembers its last
size and desktop position and will restore itself to that size and
position until you change it. If you position it partially or fully
off the desktop, it will restore itself fully on the desktop.
File Size Limitation
The application was designed to read files up to 4 megabytes. Files
that large take awhile to read and display, even on my Pentium.
Display Frame Paging
With Windows 95, I had hoped that the display limitations for list
boxes et. al. would no longer be a concern. In fact, I assumed that
only to find out that I can only display 32767 lines in a list box.
As a result, files over 500k cannot be displayed in a single display
frame. To overcome this limitation, I allow you to switch display
frames using the Up (cyan) and Down (yellow) arrow buttons on the
tool bar or selecting the Next/Previous Display Frame option from the
View Menu. For those of you who have NT, forget this paragraph.
Finding/Modifying Strings
The built in search facility (Find from the search menu) will only
search for ASCII characters. A search repeat capability has been
provided by selecting Find Again from the menu or pressing the F3
key. Found strings are brought into view and the line highlighted by
a red enclosing rectangle. Double click on any highlighted line to
modify its contents. You are allowed to modify 16 characters at a
time (1-line). The modification line is displayed in hexadecimal
format and any modifications you make must be in that same format.
The ASCII equivalent for each byte in the modification line is
displayed above the edit control. The ASCII character set is
displayed below the edit control with the corresponding hexadecimal
equivalent for each character to assist you.
The application is easy to use. Select the file you wish to read
from any drive/directory on your system and select OPEN to begin.
