c - CheckSum for a struct - 


  UInt16 चेकसमअपडेट (LOG_ENTRY_TYPE * पॉइंटर, UInt16 आकार) {UChar * डेटा; डेटा = सूचक; UInt16 chk = 0; जबकि (आकार -) {chk + = * डेटा ++; } वापसी chk; } // मेसेज डेटा स्ट्रक्चर टाइपिंगफेप टाइपएफेफ स्ट्रीट {TIMESTAMP_TYPE oTimeStamp; ASSERT_ID_TYPE ucAssertID; इंट 16 iData1; इंट 16 iData2; UInt16 UIChecksum; } LOG_ENTRY_TYPE;

TIMESTAMP_TYPE एक संरचना है जिसमें एक 16 बिट मिलीसेकंड काउंटर और 32 बिट सेकंड काउंटर है और ASSERT_ID_TYPE केवल उन चीजों की एक एन्यूम सूची है, जिन्हें मैं ऑपरेशन में देखना चाहता हूं।

तो इस प्रकार का काम करता है, लेकिन एक बार जब मूल्य 255 से अधिक हो जाता है तो कुछ बुरा हो रहा है। मुझे पता है कि एक अहस्ताक्षरित चार (UChar) 255 तक संख्या का प्रतिनिधित्व कर सकता है, लेकिन अगर मैं UChar को UInt16 में बदलता हूं तो मुझे सही उत्तर नहीं मिलता है क्या कोई मेरी समस्या को यहां बता सकता है? 

  UInt32 chk = 0; Chk + = डेटा- & gt; iData1; Chk + = डेटा- & gt; iData2;

sqlite3 - UPDATE a table from the SELECT of another one -

I have the first table article where some data is missing. In the table, articles_tmp I have a part of the missing data. So I want to update the articles. Where the path path is data in articles_tmp.path where the path is not zero . With SQLite , it does not work: update article SET path = (SELECT at.path FROM Articles_tmp as AS, WHERE at.article_id = a.id and a.asp, the text is in the form and not on. It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help? Sin CE SQL Server Syntax, which I provided, was not working, here this solution With whom I have come. A little modification of your original query, but with my "correlation" suggestion added. There is a SQL Bella for this: Here is the code: update article SET path = (SELECT path from articles_tmp AS T WHERE t.id

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ

javascript - Render HTML after each iteration in loop -

I'm trying to gradually increase the font size of text on a web page. The code works in my place, although the new HTML / CSS does not render after every iteration of the loop and when all this is done, then display only the text of 100 px size. To see the text as if it is slowly zooming, I need to do this JavaScript is down because it is being used from a different file here is what I have ... < Pre> & lt; P class = "game-title" style = "font-size: 50px" & gt; Test & lt; / P & gt; Function sleep (milliseconds) {var start = new date (). GetTime (); For (var i = 0; i & lt; 1e7; i ++) {if ((new date). GetTime () - start) & gt; Milliseconds {break; CSS ('font-size', 'parseInt ($ (' game-title '). CSS (' font-size ')) + 1 + "pixels"); } While (parasont ($ ('# text'). Css ('font-size')) & lt; = 100) {sleep (1000); IncreaseSize (); Using CSS: Use of jQuery (sample):
