• .NET Development Delayed send with smtpclient in .net 2.0

  Is there any way to force the smtpclient to send mail immediately with the .send method in system.net.mail 2.0 Right now it takes anywhere from 90 secods to two minutes before the mail is actually sent once the .send method executes. I've tried setting the object to nothing immediately after the .send method call, but no luck. The real issue for me is the send delay is also causing the smtpclient  to hold a lock on attached files that are being sent for that same 90 seconds to two minutes. I need to move the file immediately after emailing it, and right I get an exception telling me two processes can't access the file at the same time ...Show All

• Visual Basic Serial Port Hex CRC Calculation, help please.

  Hi there, My program creates this output: 0xA0+0xAF+0x01+0xAA+0x6F+0x01 which then I need to add the checksum to the end. E.g. "0xC5+0x5F+0x0C+0x00+0x00=0x130 which is therefore CRC=0x30" << from my manual (but doesn't help me). So: A0+AF+01+AA+6F+01 = 2A6 or 618 as Integer. But I need the answer as a Byte. But byte's only go to 255! No where near 618! So help please in converting this 618 into a CRC Byte, please. Thanks in advance.

• Game Technologies: DirectX, XNA, XACT, etc. Device Lost Problem

  I am having a problem with losing the device that I'm not sure about. The window can be minimized, lose focus to another app, and be resized with no problem. The problem occurs if in WinXP the user hits cntl-alt-del and then goes back (either by canceling or by unlocking later). The device can't seem to recover properly from this. Sometimes I can even continue drawing to the device after coming back but resizing it immediately breaks it (when you could resize fine before). Has anyone had this kind of experience and solved it Does somebody have a clear example in C# for how to handle the device lost, resize, and reset events cleanly in MDX ...Show All

• Visual Studio Express Editions CDate function returns 'IndexOutOfRange' error - also in VB.Net 2005 Beta2

  Hi folks, I have already reported this error in the VS 2005 Beta2 forum, but was told that it was not reproducible (VbCity and VBug, and your UK Launch team were also unable to reproduce the problem). I think I now have a lead on the issue! It also looks similar to a problem reported yesterday on the VB Express forum - 'I keep getting the out of range exception'. I have condensed the problem to two lines of code:       Dim myDate as DateTime       myDate = CDate("01/01/2005") The above error is reported on execution of the second line. This has now occurred on 6 different ...Show All

• Windows Forms NotifyIcon tooltips won't pop?

  Hello! I've got a nifty little chat client that pops a balloon tooltip when a new message is received. The problem is, is that once the user clicks the X in the tooltip, they never pop the subsequent messages. If the user never clicks the X , it does continue to pop the messages. How can I force the tooltip balloons to pop every single time Also, does anyone know how to set the timeout, so the balloon disappears after a given time Thanks! Unfortunately no message is sent when the user selects the x button: http://msdn.microsoft.com/library/en-us/shellcc/platform/shell/reference/functio ...Show All

• Windows Forms ¿Why task vision does not use Error Providers?

  "An error provider is a better alternative than displaying an error message in a message box, because once a message box is dismissed the error message is no longer visible".  MSDN Documentation. In the tutorials for validating data in .NET, it says that you should use System.Windows.Forms.ErrorProvider to show the fields that have invalid values, but TaskVision uses ...Show All
