Every time I try to make an Event OnClick for a Button in my
application, I do doubleclick by mouse on it ....
Every time it raises an exception message:
 "The component editor of class "TDefaultComponentEditor" has created
the error: "Unable to find method. Please fix the error shown in the
message window."
Is this a normal behavior, or I have some bad luck ?
Thanks!

Hi

This happen in general in this case
Code: [Select]procedure TForm1.Button1Click(Sender: TObject);
begin
  end;
end;

begin without end, or end without begin or another case too.
Fix your code and try again.

I did describe the error message with the bold black text above.

My code is:
var
  Form_TMPSM:  TForm_TMPSM;

implementation

initialization
  {$I unit_tmpsm_.lrs}

end.

1. I did uninstall the Lazarus ( It was installed at D:\#LAZARUS );
2. I did install new Lazarus at D:\LAZARUS;
3. The above error message does not appear anymore;
4. It appears new message informing me that Lazarus can not find
debugger at D:\#LAZARUS\mingw\bin\gdb.exe
5. I did copy from D:\LAZARUS\mingw\bin\gdb.exe to
D:\#LAZARUS\mingw\bin\gdb.exe
6. There is no more errors !!!! 

May be I need to unistall the Lazarus again, and install it at
D:\#LAZARUS ....
I will do this ...

It is possible that something doesn't like the "#" in your path.
There are known issues with spaces in the path too.

If you uninstall/reinstall lazarus your settings are kept. They are in
your user's home folder:
C:\Users\martin\AppData\Local\lazarus

The will contain the old debugger and fpc path (which all can be
adapted through Environment / options

If you want a fresh install with complete new settings you can delete
the folder.

You can also keep more than one set of settings by using --primary-
config-path="C:\foo" (add to commandline, using a windows shortcut)

Thanks Martin_fr,
1. I did uninstall the last installed LAZARUS
2. I did delete the directory:
 D:\Documents and Settings\emo\Local Settings\Application Data\lazarus
3. I did install a new LAZARUS at D:\LAZARUS
4. Everything works fine
