how to read the value from excel in c# without using third party dll? -

-

मेरे पास एक एक्सेल फ़ाइल है जिसका नाम strings.xls C:

यहां छवि विवरण दर्ज करें 

  Excel .अनुप्रयोग excelApp = नया Excel.Application (); स्ट्रिंग वर्कबुकपाथ = "c: /strings.xls"; एक्सेल। वर्कबुक एक्सेलवर्कबुक = नल; {ExcelWorkbook = excelApp.Workbooks.Open (कार्यपुस्तिका पृष्ठ, 0, गलत, 5, "", "", गलत, Excel.XlPlatform.xlWindows, "", सत्य, झूठी, 0, सत्य, झूठी, झूठी) का प्रयास करें; } पकड़ {excelWorkbook = excelApp.Workbooks.Add (); } Excel.Sheets excelSheets = excelWorkbook.Worksheets; स्ट्रिंग चालूशेट = "शीट 1"; Excel.Worksheet excelWorksheet = (Excel.Worksheet) excelSheets.get_Item (वर्तमान पत्रक); Excel.Range एक्सेल सेल = (Excel.Range) excelWorksheet.get_Range ("ए 1", "ए 1"); ExcelCell.Value2 = "हाय वहाँ";    
 
 
 आप नहीं कर सकते।  
 चूंकि यह XLS फ़ाइल है (एक बाइनरी प्रारूप), सरल समाधान उस मान को प्राप्त करने के लिए एक्सेल (माइक्रोसॉफ्ट जेट) ओएलई डीबी ड्राइवर का उपयोग करना होगा।  
 यदि आप XLSX फाइलें प्रदान करने के लिए प्रक्रिया बदल सकते हैं, तो आप फिर सादे .NET में खोल सकते हैं और एक्सएमएल फाइलों के मूल्यों को पार्स कर सकते हैं।

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.
