Is there a better, more elegant (and/or possibly faster) way than boolean isNumber = false; try{ Double.valueOf(myNumber); isNumber = true; } catch (NumberFormatException e) { } ...? Edit: Since I can't pick two answers I'm going with the regex one because a) it's elegant and b) saying "Jon Skeet solved the problem" is a tau...
I need to compare 2 strings in C# and treat accented letters the same as non-accented letters. For example: string s1 = "hello"; string s2 = "héllo"; s1.Equals(s2, StringComparison.InvariantCultureIgnoreCase); s1.Equals(s2, StringComparison.OrdinalIgnoreCase); These 2 strings need to be the same (as far as my application is concerned...

My question is, I'd like to minimise (if ...
FromIp contains "192.168.1.1". I want to get the last number, but I can't figure out what's wrong here: Dim str As String str = FromIP.Text.Substring(FromIP.Text.LastIndexOf("."), FromIP.Text.Length).ToString() MessageBox.Show(FromIP.Text.Length) ...

I'm trying to split a string up into words and punctuation, adding the punctuation to the list produced by the split. For instance: >>> c = "help, me" >>> print c.split() ['help,', 'me'] What I really want the list to look like is: ['help', ',', 'me'] So, I want the string split at whitespace with the punctuation split from the wo...
Hey guys. Currently I am working very basic game using the C++ environment. The game used to be a school project but now that I am done with that programming class, I wanted to expand my skills and put some more flourish on this old assignment. I have already made a lot of changes that I am pleased with. I have centralized all the dat...

What I need to do is convert a C# character to an escaped unicode string: So, 'A' - > "\x0041". Is there a better way to do this than: char ch = 'A'; string strOut = String.Format("\\x{0}", Convert.ToUInt16(ch).ToString("x4")); ...
My users will import through cut and paste a large string that will contain company names. I have an existing and growing MYSQL database of companies names, each with a unique company_id. I want to be able to parse through the string and assign to each of the user-inputed company names a fuzzy match. Right now, just doing a straight-...
I have a shell script with this code: var=`hg st -R "$path"` if [ -n "$var" ]; then echo $var fi But the conditional code always executes because hg st always prints at least one newline character. Is there a simple way to strip whitespace from $var (like trim() in php)? or Is there a standard way of dealing with this issue?...
Using Java, I need to encode a Map<String, String> of name value pairs to store into a String, and be able to decode it again. These will be stored in a database column, and will probably usually be short and simple, so the common case should produce a simple nice looking line, but shouldn't corrupt the data, even if it contains unexpe...
How can I remove the very first "1" from any string if that string starts with a "1"? "1hello world" => "hello world" "112345" => "12345" I'm thinking of doing string.sub!('1', '') if string =~ /^1/ but I' wondering there's a better way. Thanks! ...
Requirements: Must be able to use C strings as well as C++ strings Fast No maps No templates No direct lookup, i.e. index might be out of bounds. Index is not consecutive Enums and strings contained in one header file Only instantiate what you use. This is what I have come up with so far: - test.hh - // Generic mapper // // The id...
I'm looking to build a query that will use the non-clustered indexing plan on a street address field that is built with a non-clustered index. The problem I'm having is that if I'm searching for a street address I will most likely be using the 'like' eval function. I'm thinking that using this function will cause a table scan instead o...

I need to lowercase everything with lower() Find where the comma is and track it's integer location value Get the first character after that comma and put it in front of the string Then get the entire last name and stick it after the first init...
Does string immutability work by statement, or by strings within a statement? For example, I understand that the following code will allocate two strings on the heap. string s = "hello "; s += "world!"; "hello" will remain on the heap until garbage collected; and s now references "hello world!" on the heap. However, how many strings...
I'd like to split a string using one or more separator characters. E.g. "a b.c", split on " " and "." would give the list ["a", "b", "c"]. At the moment, I can't see anything in the standard library to do this, and my own attempts are a bit clumsy. E.g. def my_split(string, split_chars): if isinstance(string_L, basestring): ...
Hi, I am trying to create a DLL for authentication using Java and JNI. To create the DLL, I have created a Win32 application whose Character Set and Runtime Library information are Multi-Byte String and Multi-threaded (/MT) respectively. I have tested the DLL on WinXP with valid and invalid user credentials. Both work fine. I need t...
