serial port does not exist in current context: c# -

यहां कोड है: 

  सिस्टम का उपयोग कर; System.Collections.Generic का उपयोग कर; System.ComponentModel का उपयोग कर; System.Data का उपयोग कर; System.Drawing का उपयोग कर; System.Linq का उपयोग कर; System.Text का उपयोग कर; System.Windows.Forms का उपयोग कर; System.Threading का उपयोग कर; नामस्थान WindowsFormsApplication1 {सार्वजनिक आंशिक श्रेणी के फॉर्म 1: फ़ॉर्म {सार्वजनिक फॉर्म 1 () {InitializeComponent (); } सार्वजनिक वर्ग थ्रेडवर्क {निजी स्थिर Serialport serialPort1; सार्वजनिक स्थिर शून्य DoWork () {serialPort1.Open (); serialPort1.Write ( "एटी + CMGF = 1 \ r \ n"); //Thread.Sleep(500); serialPort1.Write ( "एटी + CNMI = 2,2 \ r \ n"); //Thread.Sleep(500); serialPort1.Write ( "एटी + CSCA = \" + +४७९०००२१०० \ "\ r \ n"); //Thread.Sleep(500); SerialPort1.डेटा पुनर्प्राप्त + = सीरियल पोर्ट 1_DataReceived_1; }} निजी शून्य फॉर्म 1_लोड (ऑब्जेक्ट प्रेषक, इवेंटएरग्स ई) {थ्रेडस्टार्ट मायट्रेड डिलीगेट = नया थ्रेडस्टार्ट (थ्रेडवर्क। डूवर्क); धागा myThread = नया थ्रेड (myThreadDelegate); myThread.Start (); } निजी शून्य धारावाहिक PORT1_DataReceived_1 (ऑब्जेक्ट प्रेषक, System.IO.Ports.SerialDataReceivedEventArgs ई) {स्ट्रिंग प्रतिक्रिया = सीरियल पोर्ट। रीडलाइन (); This.BeginInvoke (नया विधि Invoker (() = & gt; textbox1.AppendText (प्रतिक्रिया + "\ r \ n"))); }}}

और मुझे इस लाइन पर एक त्रुटि मिलती है: 

  स्ट्रिंग प्रतिक्रिया = सीरियल पोर्ट। रीडलाइन ();

यह कहता है ::

त्रुटि 1 नाम 'serialPort1' वर्तमान संदर्भ में मौजूद नहीं है C: \ Users \ alexluvsdanielle \ AppData \ Local \ Temporary Projects \ WindowsFormsApplication1 \ Form1.cs 44 31 WindowsFormsApplication1

मैं क्या कर रहा हूँ गलत?

serialPort1 की परिभाषा को Form1.ThreadWork वर्ग के बजाय Form1 वर्ग में स्थानांतरित करें।

जहां यह फिलहाल है, Form1.ThreadWork वर्ग में, यह केवल Form1.ThreadWork वर्ग के सदस्यों द्वारा देखा जा सकता है, न कि Form1 वर्ग।

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k])

windows - Heroku throws SQLITE3 Read only exception -

After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's...

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa...
