Dear Petit, Yeah, I figured there was some reference to the source files. But I'm a web developer and not a C programmer. So even if I look through the source code, I wouldn't know what to do. I'm hoping someone here might be able to explain to me if this is infact a bug in Mono or not. I'm thinking it probably is seeing as how my web app works in Windows just fine.
Can anyone please take a look and let me know what the problem is. I'm desperately trying to get my app ported to Linux and Mono and this is stopping me. At least tell me if it is a bug and if it is fixable or not. Thanks. _____ From: Petit Eric [mailto:[EMAIL PROTECTED] To: Wael Zeenni [mailto:[EMAIL PROTECTED] Cc: [EMAIL PROTECTED], mono-devel-list@lists.ximian.com Sent: Tue, 26 Aug 2008 06:09:26 -0400 Subject: Re: [Mono-dev] Controls within a control in ASP.NET I'm not Mono or ASP expert and Mono team should better answer, but it seem you have line number who refer to mono source code "C:\cygwin\tmp\monobuild\build\........."
