मेरे पास डेटाबेस तालिका & gt; & gt; 

  (स्ट्रिंग) (फ्लोट) (फ़्लोट) ) (फ्लोट) व्यापार नहीं | Buy_Sell | ट्रेड_क्टी | Market_Price 205412 1 50 300 205487 2 30 350 208754 1 20 200   
 इस तालिका में कॉलम Buy_Sell है खरीदें = 1, बेचें = 2  
 जब मैं ग्रिड को बाँधता हूं, तब मान दिखाए जा रहे हैं।  
 लेकिन, मैं उन्हें ग्रिड में & gt;  <पूर्व> <कोड> व्यापार नहीं | Buy_Sell | ट्रेड_क्टी | Market_Price 205412 खरीदें 50 300 205487 30 350 205487 बेचें 20 200 खरीदें   
 मैं ऐसा कैसे कर सकता हूं?  
 मैंने निम्न कोड के साथ बस ग्रिड को बाध्य किया है & gt;  <पूर्व>  प्रयास करें {con.Open (); Da = नया SqlDataAdapter ("चुनें ..., ट्रेड नोवो, खरीदें_जेल, ट्रेडक्टी, मार्केटप्रस", कॉन); डाटासेट डीएस = नया डाटासेट (); da.Fill (डी एस); // gvTradeFile.DataSource = ds.Tables [0]; GvTradeFile.DataSource = ds.Tables [0]। एएनएनमेरेबल ()। चयन करें (डी = & gt; नया {TradeNo = d.Field & lt; स्ट्रिंग & gt; ("ट्रेड नो"), Buy_Sell = d.Field & lt; float & gt; ("Buy_Sell") == 1? "खरीदें": "बेचना", ट्रेड क्वालिटी = डी। फ़िल्ड & lt; float & gt; ("ट्रेडक्टी"), मार्केट_Price = डी। फ़िल्ड & lt; float & gt; ("मार्केटप्राइस")}); } पकड़ (अपवाद पूर्व) {संदेश बॉक्स। दिखाएँ (ex.Message); }   
 यह कोड मुझे कोई अपवाद नहीं दे रहा है, लेकिन मुझे ग्रिड में भी न दिखा रहा है।  
 क्या LINQ क्वेरी के अलावा कोई अन्य तरीका है जो इस तरह का परिणाम है ?   
 
 
  चुनें  विधि एक  IQueryable  परिणाम देता है । यह डेटा बाध्यकारी के लिए सही तरीके से काम करने के लिए पर्याप्त नहीं है, क्योंकि  DataSource  संपत्ति  आईआईएलआईटी ,  IListSource ,  IBindingList  के ऑब्जेक्ट का इंतजार कर रहा है > या  IBindingListView ।  
 रिज़ॉल्यूशन काफी आसान है, हालांकि - बस अपने परिणाम डेटा सेट को कुछ ऐसे इंटरफ़ेस में परिवर्तित करें, उदाहरण के लिए बस  toList < कोड>:  
 । चुनें (d = & gt; नया {...})। ToList ();

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from. NSString will be used instead of NSMutableString . - (UITableViewCell *) TableView: (UITableView *) Table View CellForOutPath: (NSIndex...
