[ad_1] You can convert your number to a string, split into characters and join these again with spaces: int i = 690110; char[] chars = i.ToString().ToCharArray(); // To get a formatted string: string s = string.Join(” “,chars); // To get the digits: int[] digits = chars.Select(x=>Convert.ToInt32(x)).ToArray(); 3 [ad_2] solved How to give mutiple spaces to … Read more
[ad_1] The first error is because of this: Array myPort;. That’s not how you declare an array, Array is an abstract class that provides methods to operate on arrays. SerialPort.GetPortNames() returns a string array so you can either declare a string array or just remove the Array myPort; declaration and replace the other line with … Read more
[ad_1] The regular expression is: ^((?!(?<ch>.)\k<ch>\k<ch>)(?!012|123|234|345|456|567|678|789|890)[0-9]){8,}$ The (?!(?<ch>.)\k<ch>\k<ch>) will check for the same character repeated thrice. Note that for the various contiguous sequences I had to put them in a list of possible sequences, (?!012|123|234|345|456|567|678|789|890). [0-9] is the character that will be accepted as valid. The {8,} is for the minimum length. 1 [ad_2] solved … Read more
[ad_1] Just to iterate on Jens’ comment, we have to guess: What is your expected output when additional information appears, e.g. http://therealzenstar.blogspot.fr/somedata.html. Is it still blogspot.fr? Are such examples needed to be adresed? You said you want to replace “everything else” with “”. Replace() will replace everything that is matched with what you want.

[ad_1] I’m pretty sure that the problem is the space in the name of your Faculty Name column and that this has nothing to do with the use of AND or OR. Please try: sql = “Update [Sheet1$] set A1 = ‘a’ ” + “where Designation = ‘Prof(senior)’ and [Faculty Name] = ‘bob'”; 1 [ad_2] … Read more

For some you have to go through a series of procedures to get everything to the latest so it’s not necessarily developers that can trudge through this when you … Read more
[ad_1] Get yourself and enum with the values. Easier to handle than strings. public enum Vals { IF, THEN, ENDIF, ELSE, } We have a method for comparing if the next value is correct pair with the current. public static bool IsValidFollower(Vals val1, Vals val2) { if (val1 == Vals.IF) return val2 == Vals.THEN; if … Read more
[ad_1] If your app runs fine on .NET Core 5 in Windows (not full .NET Framework), then by definition it should run on .NET Core 5 on OS X and Linux. However that’s still too optimistic, as file paths and so on are still different enough to impact the way you write your code. Thorough … Read more
[ad_1] When you have declared the column as INTEGER PRIMARY KEY, you don’t need to do anything because the database automatically uses the next value after the largest value in the table. When you have declared the column as INTEGER PRIMARY KEY AUTOINCREMENT, the current counter is stored in the sqlite_sequence table. You can simply … Read more

[ad_1] This is a fairly simple task: string url = @”http://google.com/adi/727412;sz=728×90;ord=$RANDOM?”; if (url.Contains(@”/adi/”)) { int pos = url.IndexOf(“;ord”); //// Find first occurence of Ord parameter url = url.Insert(pos, “;click=$CLICK”); //// Insert text at position } Edit: To accomplish the task for multiple occurences I used a solution from this thread. { string url = “<google.com/adi/727412;sz=728×90;ord=$RANDOM?>; … Read more
[ad_1] Do same null-check as you did when invoked action first time: catch (Exception ex) { if (onError != null) onError(ex); return; } If you want to avoid null-checks – attach dummy handler to Action delegate at the top of your method: onError += (e) => {}; 2 [ad_2] solved Can not pass error via … Read more
