Re: Memory Leak [EDITED] Dave Kreskowiak27-Jul-05 6:33 Dave Kreskowiak 27-Jul-05 6:33  It's not really the memory that's the problem, but the unmanaged handle-based resources that the form holds onto. If used frequently enough, and not freed by explicitly calling .Dispose(), they can be exhausted, causing an "Out of memory" exception, even though memory is not what you ran out of. The GC doesn't track handle usage, and so, can't tell when the system is running low. If the GC can't tell this, it can't speed up Disposing and Finalizing the objects it's supposed to collect.

Re: Non-Standard port configuration for SmtpMail S. Senthil Kumar26-Jul-05 5:13 S. Senthil Kumar 26-Jul-05 5:13  No, unless you are running the mail server. All standard mail servers listen on port 25, so I guess that leaves you with no option but to use 25. Regards Senthil _____________________________ My Blog | My Articles | WinMacro Re: Non-Standard port configuration for SmtpMail WetRivrRat26-Jul-05 5:48 WetRivrRat 26-Jul-05 5:48  I thought that it didn't matter what outgoing port you sent on it would still connect on the proper incomming port. but I guess not? does that mean that the smtpmail uses the configuration of the local smtp server to send? so if i were to load it on a local client and set the local smtpserver at the non-standard # it would work, but other wise won't?

Re: Non-Standard port configuration for SmtpMail S. Senthil Kumar26-Jul-05 6:35 S. Senthil Kumar 26-Jul-05 6:35  Sorry, I misread your question. You're right, the outgoing port doesn't matter.

Regards Senthil _____________________________ My Blog | My Articles | WinMacro Re: Non-Standard port configuration for SmtpMail WetRivrRat26-Jul-05 7:28 WetRivrRat 26-Jul-05 7:28  yes, it should be, i don't know for certain. but even if i send it out on say 26 it should still receive right, if it is recieveing smtp. in otherwords if i were to send mail on port 80 to mail.blah-blah.com it would know (if the router/firewall it's setup properly)to accept incomming traffic to mail.blah-blah.com on internal port 25 right? so i should be able to send outgoing mail on whatever port i want, as long as the recieveing server is configured to recieve mail from mail.whatever.whatever. or am i just really off in my thinking here?

Port 80 is for HTTP, it most certainly won't be expecting SMTP messages there. So, the answer for your question is, yes, you should use port 25 for sending mails. I got sidetracked because I thought you were talking about the port number of the client which is sending the mail.

But I figured out a way. It seems it will still send outgoing mail if I relay off another server. So i'm up now. thanks!

WetRivrRat26-Jul-05 4:33 WetRivrRat 26-Jul-05 4:33  Is it possible to configure the SmtpMail.Send(); to send mail without having to have smtp installed locally? I need to be able to send mail internally(intra-net) without having to install smtp on every client, as well without having to access the local mail client, as we don't have outlook or outlook express installed on the clients. We are however in a Novell / Groupwise environment and I don't know anything about how to intergrate with GW, so I would like to stay away from trying to intergrate, but if it is the only way then i'm open to making it work.

No, the .NET Framework doesn't have built in support for masked text boxes as of version 1.1 (I think 2.0 will.)

Comparing Doubles Using Epsilon in C# Member 197084526-Jul-05 4:09 Member 1970845 26-Jul-05 4:09  The help in Visual Stuio on double.Epsilon states the following: "Two apparently equivalent floating point numbers might not compare equal because of differences in their least significant digits. For example, the C# expression, (double)1/3 == (double)0.33333, does not compare equal because the division operation on the left-hand side has maximum precision while the constant on the right-hand side is only precise to the visible digits. Instead, determine if the two sides of a comparison are close enough to equal for your purposes by comparing whether the absolute value of the difference between the left and right-hand sides is less than Epsilon." Epsilon is still going to be way smaller than the error due to the precision of the double's mantissa. Instead of trying to use epslilon I compare my doubles like this: if (Math.Abs(exp-det) > Math.Abs(exp/Math.Pow(2.0, 64.0-12.0))) { throw new MyException(" BufferComparison failed " + det + " != " + exp); } Is there a better way? -or- Is there a correct way to use Epsilon?

I am able to get the entire folder emails detail but not exactly the selected email. Thanks, Inba S. dialog access problem Dan Neely26-Jul-05 3:23 Dan Neely 26-Jul-05 3:23  I have an app with 3 major dialogs. The parent dialog, a modal work dialog, and a help dialog. Since I only want a single copy of help open at a time I had the work dialog call a method of the parent which only created a new help dialog if there wasn't already one open. This works fine if the help button in the work dialog is clicked and the help dialog isn't open. In that case Help's freely available and the user can switch between the help dialog and the work dialog at will. The problem is if the help dialog is first opened in the parent it's inaccessable from the work dialog. The only workaround I can think of is to have the work dialog first kill the help one, and then reopen it but that's a kluge and looses the users place. Is there a more graceful way to do it? Re: dialog access problem Patric_J27-Jul-05 4:38 Patric_J 27-Jul-05 4:38  Interesting problem, how do you unlock a modeless dialog locked by a modal dialog? Sorry to say, I have no good answer and looking at the lack of responses to your question the community seams to have problems with it also. Can't you make the help dialog as a standalone application which you kill when the parent dialog is shutdown? Only problem I see with this solution is if you need to communicate with the help application, which is more difficult than communication within an application, so then it might not be worth it. Here's a link how to make a single instance application: www.codeproject.com/csharp/singleinstance.asp /Patric My C# blog: C# Coach Re: dialog access problem Dan Neely27-Jul-05 5:28 Dan Neely 27-Jul-05 5:28  That's an solution I hadn't thought of. It wouldn't be a problem now, but context sensitive help is in the features wishlist so it could become an issue in the future.
