Of course you are right.

Adding bad desing with fonts and error in Perl 5.10 you can see my problems... :( But thankfull Jeremy code I fixed the error and using Perl 5.8 version with changes in my application give the result that I have quite stable application now. I tried to do it in 5.12 but I didn't manage. At first ExtUtils::FakeConfig from cpan had no 5.12 version. I thank I corrected it but compilation Win32::GUI with gcc failed (tests showed it). Because I can't find ppm for 5.12 so I think I have made a mistake writing the information about Win32::GUI in Perl 5.12. Sorry for that. > maybe it would be a good idea to add a -backgroundbrush option, so you > can pass a Win32::GUI::Brush object to it and the same GDI object will > be used for all controls, as with fonts. This would be fine for I use them (backgrounds) synchronized in my windows so I can get the same colour to the quite big group of widgets. cheers Waldemar. ------------------------------------------------------------------------------ Enable your software for Intel(R) Active Management Technology to meet the growing manageability and security demands of your customers.
