Alternative path for .elf file

[JohaViss]

Hello,

We have an application that is capable of running from a CD-ROM.
When there is an error there is no .elf file written because you can't write on a CD-ROM.
Is it possible to write the .elf file to the directory of the app when it's allowed to write and to another dir when it's not allowed to write. :)


Second question: :cool:
Is it possible to specify the output dir with a short notation?
We can't be sure what the name of a system dir is ('WINDOWS' or 'WINNT')
We would like to use a style like this {win} to indicate the Windows dir and {sys} for a SYSTEM32 directory.

I think you have to write code to testing this and then set the choosen
directory

You can ask for the registry or environment variable to get the system
directory or temp directory or others...

type set in a command prompt.
exemple:

TEMP=C:\DOCUME~1\perinfo\LOCALS~1\Temp
TMP=C:\DOCUME~1\perinfo\LOCALS~1\Temp
HOMEPATH=\Documents and Settings\perinfo
SystemDrive=C:
SystemRoot=C:\WINDOWS
windir=C:\WINDOWS
....

Yes, it's so! :)

Or use the GetWindowsDirectory/GetSystemDirectory Windows API! :)

NOTE: The problem is not only with CD-Roms. You should design your
application to run as non-administrator user. (For example, at home, all my
kids have their accounts as users and I'm the admin with a password, they
use finger-print reader to log-in. cooool)
non-admin users cannot write to "\program files", where your app is usually
installed to. So I use this piece of code to redirect the ELF file to the
desired path under the user profile


// Direct the log to a reasonable path
procedure MyNotify(ExcRecord: TEurekaExceptionRecord; var Handled: Boolean);
Function Env(Name:String):String;
Var Res: Array[0..255] of char;
begin
Res := #0;
GetEnvironmentVariable(PCHAR(Name), Res, sizeof(Res));
Result := Res;
end;
Var Path : String;
begin
Path := Env('UserProfile');
if Path = '' then Path := '\'; // On Win9x, %UserProfile% is not defined
ExcRecord.CurrentModuleOptions.OutputPath := Path
end;

// this goes inside the project's (DPR) main begin-end block
...
ExceptionNotify := MyNotify;
...


Hope this helps

Perfect! :)

Using your suggestion, I have created a new EurekaLog 5.0.5 RC 2.

This new version check if the file to write is writable and if it isn't
move it to the %UserProfile%\EurekaLog folder.

Also for the Log-File and for the EurekaLog.ini file (used to store the
Exception Dialog state).

Can you test it please?

Hello,

I have tested the solution you have build. :cool:
It works perfect.
Finally I don't have to worry that I lose the error messages and have to ask the users what was wrong.

Thank you very much. :)

When can we expect the final version?
