Hi all,
Just when I thought I'd got my database
application put to bed some-one got smart and ruined it. I need some bright
ideas.
You may remember my hastles having my program
installer create a desktop icon to launch the application. That's now fixed
but I have just been asked to allow for multiple instances of the
program with each having a different directory in which to place its
database.
My thought was to allow the installer to allow
for three options viz:
1. Default directory and by
default the database to be in the same
one
2. Separate directories for other
instances of the program and their associated database files
3. Separate directory(s) for
additional data bases.
The idea being that the one program or copies
thereof can be dedicated to different customers and yet readily
accessed.
First problem is to be able to change the database
table name and location for each separate program. I attempted to do this by
passing the data as a parameter as each program is called, thus
-
if ParamCount <> 0 then
begin MainForm.Table1.Active := FALSE; MainForm.Table1.DataBaseName := ParamStr(1); MainForm.Table1.Active := TRUE; end; It works in a limited fashion but isn't reliable. I need another suggestion. Secondly although I can have the
installer create separate programs with separate parameters for each of the
separate program calls, or even to call the same program with different
parameters for each database being used, they all end up as an alteration of the
same shortcut icon's "Target" and "Start
in" property fields, as each is installed. I want one for each different
database. So that is my second heartache.
Finally, something quite different. How do I set up
a progress bar to show the progress of reading or writing a disk file. It must
be very easy as everyone but me can do it ? Pointer to example
please.
Thanks for your help
Colin.
