In addition to the previous mail:
Using the unc file-name, the file extention is also formatted to the 8.3 dos
notation : my 'normal' extention has a length of 6 characters and normally I do
compare these extention before trying to open the file....
...Is there a way to retrieve the 'old' extention from the 8.3 name ?

Subject: [delphi-en] Pamater logic and unc path names
Hello
Is there some logic when a parameter passes the 'explorer' name and when a unc
name?
I have a strange problems using startup parmeters within my exe.
I would like to start a file using it's assosiated program. Therfor it's using
the register key found in
\hkey_classes_ root\fileextFile \shell\open\ command
I've added a showmessage to my exe to give me an indication on what parameters
arrive at startup:
The original program-exe was installed using an 'installation wizard' and the
key-value found within this register key is pointing to my installation
directory: D:\installation\ CalculatieXE %1
All parameters arriving at this location will be using the unc notation (spaces
will not be used and ~ a lot...). However this location does not provide me
enough debudding options: therefor I've altered the register key value to
D:\delphi\projects\ ontw\WecapXE\ CalculatieXE %1 (my DElphi development
location)
What surprices me is that all parameters arriving at startup not are NOT using
the unc-notation and therfor parameters are not valid if the "file to
open"-path contains spaces.
Files will work as long as the filename does not contain spaces: as soon it
does contain spaces it's pamater become useless: \
e.g. file at c:\te mp\1.ext will arrive as parameter 'c:\te'
I know the solution is to alter my D:\delphi\projects\ ontw\WecapXE\
CalculatieXE %1 to D:\delphi\projects\ ontw\WecapXE\ CalculatieXE "%1" , but
why I sometimes get the unc names and sometimes not, surpices me a lot.
I also now did find out if I change the dir name where the exe is located, it
will force all parameters to use the ~ name...
Is there some logic when a parameter passes the 'explorer' name and when a unc
name? Is this determained by the dirname where the exe is located? Does it
matter if the 'file-to open' is located on another disk?
Hope you have some answers
Regards
Andries
