Set Time outs on Serial Port - C# Discussion Boards

Re: How to send .xlsx file as an email attachment in C#?

29-Sep-15 3:50

Hi,

I am trying to send a *.xlsx file as an email attachment in #c for that we write the below code

Attachment item = new Attachment(fileName.xslx,MediaTypeNames.Application.Octet);
item.TransferEncoding = System.Net.Mime.TransferEncoding.QuotedPrintable;
mail.Attachments.Add(item);
mail.IsBodyHtml =true;
mail.BodyEncoding =Encoding.UTF7;
mail.HeadersEncoding =Encoding.UTF7;

stmp.Send(mail);

By doing this in some machines we are able to send the mail successfully,but in some machines we are not able to send and also from those machines we are getting a mail with junk characters as body of the mail.

Please help us if anybody knows anything related to this(we are suspecting it might be machine settings problem,but we dont know what settings we need to change)

Why are you using UTF7? That's probably the issue. You should be using UTF8.

There are only 10 types of people in the world, those who understand binary and those who don't.

Hi We tried with UTF8 also that is also not working,but strangely as mentioned above even with UTF7 it is working on some machines

I have this C++ code for setting timeouts on serial port

C++

COMMTIMEOUTS *timeouts = new COMMTIMEOUTS ;
memset(timeouts, 0, sizeof(COMMTIMEOUTS)) ;
timeouts->ReadIntervalTimeout          = ReadIntervalTimeout ;
timeouts->ReadTotalTimeoutMultiplier   = 5 ;
timeouts->ReadTotalTimeoutConstant     = readTimeOut ; //...
timeouts->WriteTotalTimeoutConstant    = 0 ; //
timeouts->WriteTotalTimeoutMultiplier  = 2*BaudRate/8 ;
const bool ret = SetCommTimeouts(*hDev, timeouts) != FALSE ;
delete timeouts ;
m_currentTimeOut = readTimeOut ;

I need to rewrite this in C#. For SerialPort class I found these properties:

C++

_serialPort.ReadTimeout = 500;
_serialPort.WriteTimeout = 500;

Are they equivalent? It seems there are more parameters in play in the C++ code. How can I approach this? Or maybe other parameters are not needed? What is the best way to transform that C++ code to C#?

Yes, I believe you are correct. See https://msdn.microsoft.com/en-us/library/system.io.ports.serialport(v=vs.110).aspx[^] for the SerialPort class. And yes, C# will be easier than C++, that is intentional.

Not really, see on C++ there are more parameters about time out whereas on C# there is only 2. So it means I can't do exact mapping...?

Yes exactly, C# is a much easier language than C++ and is a high level language; whereas, C++ is a low-level language. C++ will likely always give equal to or greater control to the developer.

I think we don't understand each other. Please see here: http://stackoverflow.com/questions/32844940/rewrite-serial-communication-on-c-sharp[^], I asked similar question. My problem is I have C++ code which establishes serial communication and I need to rewrite this to C#.
Which approach should I take? If I take SerialPort, it seems I can't duplicate and tune all the parameters which C++ structures allow like DCB.
Should I take Pinvoke way (http://forums.codeguru.com/showthread.php?182234-serial-ports-C[^]) instead - and make 100% duplicate? Is that necessary?

Yes, I understand that. And I'm telling you that C# does not expose all the same features that you can access in C++. So, either do it in C++ with the code you have or write it in C# and let the OS handle some of those properties for you that C++ does allow you to set.

In C# you mean to write it using SerialPort class and see if it works?

And if not, then try Pinvoke calls and duplicate the C++ code? (as in here for example? http://forums.codeguru.com/showthread.php?182234-serial-ports-C[^])

It all depends on what you are doing and what environment it is. If this is a windows application also written in C#, then yes, use the C#.

Original application is written in C++ (see for more code on the other question I linked above), and I need to rewrite to C#

Help with what? You haven't shown us the code that builds the email message so it's pretty much impossible to tell you what you did wrong.
