 |
|
Hello, I want to capture the error message in TDirectoryListBox when you
assign a non-existant drive to TDirectoryListBox->Drive. That way I can
iterate true all 26 letters of the alphabet to get the good drives. So I
dont want the user to see any error messages. I am sure the try/catch block
would work but i dont know how to use it please help.
Thanks

I don't know exactly what exception is thrown, but this should
work:
try
{
DirectoryListBox1->Drive = 'K';
}
catch (...)
{
/* the drive doesn't exist or error */
}
API GetDriveType could be useful as well.
Steve.

It's EInOutError.

Yep, the error is EInOutError. Also using your code causes my personalized
message from catch(...) to come up as planned. Thanks.
However, the BCB exception window below still comes up before my
personalized message. Is there any way to have no exception window come up
at all? Basically, I want the user to see nothing except for wat I choose
them to see.
Thanks

Running the code I posted, no exception comes up. So, I guess
either the problem is somewhere else in your code or you tried
only in debug mode and you have "Stop on Delphi Exceptions"
checked under the "Debugger options..." menu.
