c - How to get byte size of multibyte string -

-

मैं दृश्य सी में एक multibyte-character स्ट्रिंग के बाइट आकार कैसे प्राप्त करूं?

या अधिक सामान्य, मैं टीसीएचआर स्ट्रिंग के सही बाइट आकार कैसे प्राप्त करूं?

समाधान: 

  _tcslen (_T ("TCHAR string")) * sizeof (TCHAR)

संपादित करें:
मैं केवल रिक्त समाप्त स्ट्रिंग्स के बारे में बात कर रहा था। / P>

, _tcslen से संगत है strlen जब _ एमबीसीएस परिभाषित है strlen स्ट्रिंग में बाइट्स की संख्या वापस कर देगा। यदि आप _tcsclen का उपयोग करते हैं, तो _mbslen से मेल खाती है, जो कि multibyte वर्ण की संख्या देता है।

इसके अलावा, multibyte तार नहीं करते हैं (एपीएआईके) में एम्बेडेड नल, नं।

मैं पहली जगह में एक multibyte एन्कोडिंग के उपयोग पर सवाल करता हूं, हालांकि ... जब तक कि आप कोई लीगेसी ऐप का समर्थन नहीं कर रहे हों, तब तक multibyte चुनने का कोई कारण नहीं है यूनिकोड।

wpf - Line breaks and indenting for the XAML of a saved FlowDocument? -

-
Is there a way to format XAM generated when a flow document is saved? Currently, all of this is run simultaneously in one line, and I want to break it into my elements, with line break and indenting it makes it a little easier to read. Here is the code I'm using to save a FlowDocument in a WPF RichTextBox as a XAML file: // entire document around TextRange textRange Create a TextRange side = new TextRange (myRichTextBox.Document.ContentStart, myRichTextBox.Document .contentEnd); // save the file using the file (file stream fs = file. Create (filename)) {textRange.Save (fs, DataFormats.Xaml); } Savings work fine, but as I mentioned, JPAM has been generated, all this goes together, no indentation or line breaks for its various elements Is: & lt; Section xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xml: space = "preserve" Tekstelinement = "left" Lainhait = "auto" Hashipineshn = enabled = "false...

gtk - Python Window Resize -

Using Python + PyGTK Is there a signal / event way to change the window size? If so, then what is the easiest way to implement and use this signal. There is also one, so it answers the signal. Here's the minimum sample code: import gtk def (window): print 'I have resized'. W = gtk.Window () w.connect ('check-size', has been changed) w.show () gtk.main ()

c# - read full xml file data over tcp -

I'm developing an application that either the incoming data on the PC and then when I'm trying does it decodes the data to use the software with any sniffing have been stored in the dB and I can read it myself ... but my code .... this came in a format like 1651589240214931398151442251437622947132917620011138147205162160411201699123179148781675713921035101183865895219106213196222741589715384652061681391901278671232822552717812424975221242 11517622131122113236255230254211206911242051832545515823012124925217318223920523316923122925514321122343602492471242 ........ I have tried to use this System.Text.Encoding.ASCII.GetString (tcpHeader.Data) and it is working fine. But when I run it and wait for data (this is in XML format) I have found in many packages that it is difficult to read it again ... What should I do? Do I have to collect data from every packet, then add all to get the whole message? Or there is a library to do that in .net
