With CSharpProvider you have to programmatically add referenced assemblies. Did you have a look at the link I provided?

Yes I did.. and it's a really good article!(I also didn't know how to drag files..)
I'd seen you used the CSharpProvider, i just thought it could be possible also with CodeDom like i did, cause I used it to compile other kind of .cs files.
Ok, I'll switch to the CSharpProvider..
THANKS for everything!
bye

Hey
I have a textbox with values = 1 + 1,3 + 1 + 7
How can i calculate that so when i push the button calculate will give the result = 10,3
Thanks very very mutch
its really importing
|

AFAIK, this things are done by converting the arithmetic expression to it's postfix form. Do some reading on that.
|
|
|
|
|
thaks very mutch but you do not have som method like double.parse(textbox.text) or somthing like that som can help me out of here.
I used Inof.Lundin.Math but this cannon add decimal this can just add 1+1 = 2 but not 1+1,4 = 2,4
|

Just out of curiosity I downloaded the library you mentioned and it works for me. This is my small test:
info.lundin.Math.ExpressionParser exp = new info.lundin.Math.ExpressionParser();
Hashtable h = new Hashtable();
h.Add("x", "1");
h.Add("y", "1,5");
h.Add("z", "0,23");
double result = exp.Parse("x + y + z", h);
MessageBox.Show(result.ToString());
The result is 2,73 -just as expected.
EDIT:
If you want to take the expression directly from a textbox, use this code:
info.lundin.Math.ExpressionParser exp = new info.lundin.Math.ExpressionParser();
Hashtable h = new Hashtable();
double result = exp.Parse(myTextBox.Text, h);
MessageBox.Show(result.ToString());
This also works for me. However (just a guess), you might get that error because you are using incorrect decimal separator for your culture. On my machine the comma is the separator, but for you it might be the dot. Check it.

Thanks very mutch blackjac
But it still not work if i use dot ex. 1.4 then it takes it like 14 and if i use 1,4 coms with error
"No value associated with 1,4"
|
|
|
|
|
2,4 is not a valid decimal/floating-point-number in most cultures.
|
|
|
|
|
i use a culture en US ? in my web.aspx project.
|
|
|
|
|
Then you need a dot '.' not a comma ',' eg 2.453
|
|
|
|
|
Now it works.. thank thanks very much..

do you want to put all together on the screen? 1 + 1,3 + 1 + 7 if not
add a button "="
use:
int total;
click button "=" event (or other) inside put:
total = total + convert.toint32(textbox_x)

Hi,
I am using the MSCOMM for sending and getting the response from hardware in Desktop Embedded Application I am getting the following values in response of MSCOMM port:
Wrong Values :- 0x192,0x20ac,0x201a,0x201e,0x2026,0x2020,0x2021,0x2c6,0x2030,0x160,0x2039,0x152
0x17d,0x2018,0x2019,0x201c,0x201d,0x2022,0x2013,0x2014,0x2dc,0x2122,0x161,0x2039
0x153,0x17e,0x178
Instead the values should the values coming from the hardware are
Correct Values :-
0x80,0x82,0x83,0x84,0x85,0x86,0x87,0x88,0x89,0x8a,0x8b,0x8c,0x8e,0x91,0x92
0x93,0x94,0x95,0x96,0x97,0x98,0x99,0x9a,0x9b,0x9c,0x9e,0x9f
But in Dot Net the Values given above are coming in the Input of MSCOMM.When I use the above values in my code as :-
char chars = Convert.ToChar(response)
MyByte = Convert.ToByte(chars)
where response = 0x192
The 2nd line of getting MyByte is skipped by Dot Net for above values
Can anybody tell why is this happening

Hi,
From your list of expected values you appear to want 8 bit byte values but are receiving 16 bit chars. I've never used the MSCOMM component but surely a good start would be to set the input mode to binary.
com.InputMode = MSCommLib.InputModeConstants.comInputModeBinary;
At the moment it must be set to comInputModeText

You want to cast, not convert.
You serial port settings could also be incorrect.
|
|
|
|

You asked this question previously and it was suggested to you to to alter the way you're casting the incoming values, yet here is the same code. Why are you using the MSCOMM control in C#? Shouldn't you be using the SerialPort class? Anyway, the runtime doesn't SKIP the code, it throws an OverflowException, did you actually attach the debugger and step the code?

Hey Guys Need Help
I created a Console Application to send out mails. The method i used is adding reference of Using System.Web.mail
MailMessage mail = new MailMessage();
mail.To = "xxx@xxx.com";
mail.From = "xxx@xxxe.com";
mail.Cc = "";
mail.Subject = "Testing Console";
mail.BodyFormat = MailFormat.Html;
mail.Body = "Testing";
SmtpMail.SmtpServer = "xx.x.xx.xx";
SmtpMail.Send(mail);
But I gotten this error saying "The transport failed to connect to the server."
Then I used The System.Net.Mail
MailMessage message = new MailMessage();
message.From = new MailAddress("xxx@xxx.com");
message.To.Add(new MailAddress("xxx@xxx.com"));
message.CC.Add(new MailAddress("carboncopy@foo.bar.com"));
message.Subject = "This is my subject";
message.Body = "This is the content";
SmtpClient client = new SmtpClient("xx.x.xx.xx");
client.Send(message);
But I gotten this error saying "Failure sending mail.."
I am running out of ideas. Any solution or advise
Thanks A million
