HTMLInternalDocument "निम्नलिखित कोड के परिणामस्वरूप वस्तु: 

  url & lt; -myURL html & lt; -htmlTreeParse (url, useInternalNodes = T)

अब मुझे मिलना चाहिए उदाहरण के लिए प्रत्येक पंक्ति में वर्णों की संख्या की गणना करने के लिए पाठ स्वरूप में इस html ऑब्जेक्ट से एक विशिष्ट पंक्ति।

मैं आर में ऐसा कैसे कर सकता हूं?

यह देखते हुए कि आप XML पुस्तकालय का उपयोग कर रहे हैं, आपको पुस्तकालय के getNodeSet फ़ंक्शंस जैसे xpathApply । इसको xPaths पर कुछ ज्ञान की आवश्यकता है, जो फ़ंक्शन HTMLInternalDocument को पार्स करने के लिए उपयोग करता है आप ? XpathApply

ios - Subclassing UIView and adding a property -

-
I've tried UIView subclassing. Because I want an enum in my UIView so I can check whether UIView has to tap into my game twice. But I do not have much experience with subclassing and it is not working Make subclasses Build assets within a custom subclass Change sub-squares from UIView in the storyboard Change all UIView announcements from my game class in the subclassic declaration Code: #import & lt; UIKit / UIKit.h & gt; Type-FED NSNUm (NSITF, VISU SATAT) {ENNYMALAPEP, EUNDUBEBELTAP}; @ Interface bannerview: UIView @property (nonatomic, assign) viewStaat staatVanDeView; @end and declare a property in the INIT from the UIVVI. @setuphesize staatVanDeView; - (id) initWithFrame: (CGRect) frame {self = [super initWithFrame: frame]; If (self) {staatVanDeView = ENUMDubbelTap; NSLog (@ "Set"); } Healthy return; } The log is not being called, so I do not know what is wrong.

Powerbuilder 12.1 and DataWindow in Design vs Debug and Executable/Runtime -

-

But when you go into the data window in design mode, it prompts for the values ​​of those parameters, the content is only displayed, it is okay. Edit: Solve. This is due to a powerbiller that uses an integer rather than a long variable. The identity identifier in the database exceeds the upper limit of a PowerBuilder 16-bit integer (32767). I updated the logic for longer use, and resolved this problem # 1. ISSUE # 2: When I run the report code using the same data window mentioned in issue # 1 above, in debug mode, to create a new report file, this work Done - only in DEBUG mode Runtime failure - I got an error -1 during the runtime for the exact same...
