I've got a list in a Python program that contains a series of numbers, which are themselves ASCII values. How do I convert this into a "regular" string that I can echo to the screen? ...
What is the maximum length for the text string contained in a CEdit control in MFC? I get a beep when trying to add a character after the character 30001 is this documented anywhere? Can I display longer texts in a CEdit? Should I use another control? As "Windows programmer" says down below, the text length limit is not the same when th...
While editing someone else's abandoned Python script, I was trying to use mystring.find("\n", i) to get the index of the next newline in a string. But this consistently returns -1 (even when I try using "\r\n" instead of "\n"). I know there are newlines in the string, because I had just loaded it from a file. I am not very familiar wi...
I have a mysql table with albums. Each album can be a top level album, or a child album of another album. Each album has a foldername which is the name of the folder its pictures are in. Each album also has a field called parent which is the id of the parent album. So, if I have a path to an image like this: root/album1/album2/image1.jp...
I would like to remove the domain/computer information from a login id in C#. So, I would like to make either "Domain\me" or "Domain\me" just "me". I could always check for the existence of either, and use that as the index to start the substring...but I am looking for something more elegant and compact. Worse case scenario: ...
I have a string that looks like this: "Name1=Value1;Name2=Value2;Name3=Value3" Is there a built-in class/function in Python that will take that string and construct a dictionary, as though I had done this: dict = { "Name1": "Value1", "Name2": "Value2", "Name3": "Value3" } I have looked through the modules available but ...
I know this is a bit of a newbie question, but are there equivalents to C#'s string operations in Java? Specifically, I'm talking about String.Format and String.Join. ...
I've just seen this in the MS Visual Studio docs and the part in bold doesn't make sense to me. Is it wrong or am I not understanding it properly? If you run this, b appears to hold "hello" (as I would expect) and not "h". Strings are immutable--the contents of a string object cannot be changed after the object is created, although the ...
If I want to have a case-insensitive string-keyed dictionary, which version of StringComparer should I use given these constraints: The keys in the dictionary come from either C# code or config files written in english locale only (either US, or UK) The software is internationalized and will run in different locales I normally use St...
Does anyone know of a simple way to compare two strings together to generate the "amount of difference" between the two? (in a numeric value) I have been crawling google with little luck on this. And after doing some coding it's not as simple as I had thought. Any clues? ...

It is on a datarecord and I would prefer to be able to do this without assigning a new variable. I was thinking: String.Format("{0:###-###-####}", i["MyPhone"].ToString() ); but that does not seem to do the trick. ** ...

I have a Java application that's very String-heavy - it takes a feed of huge numbers of big, different String objects. Do I need to worry about the String Constant Pool for memory and performance? Is there any way to see how big the pool is at any point? ...

I have a 2 dimensional array, like so: char[,] str = new char[2,50]; Now, after I've stored contents in both str[0] and str[1], how do I store it in a string[] s = new string[2]; ? I tried s[0] = str[0].ToString(); but that seems to be an error: VC# expects 'two' indices within the braces, which means I can convert only a cha...

Hey all. I got one big question. I got a linq query to put it simply looks like this: from xx in table where xx.uid.ToString().Contains(string[]) select xx The values of the string[] array would be numbers like (1,45,20,10,etc...) the Default for .Contains is .Contains(string). I need it to do this instead: .Contains(string[])......
I'm looking for a technique (javascript, CSS, whatever ???) that will let me control the amount of a string that is displayed. The string is the result of a search (and therefore not initially known). A simple Character count approach is trivial, but not acceptable, as it needs to handle proportional fonts. In otherwords if I want to lim...

Say I wanted to get the string "text" from the string "ignore everything except this (text)" in the most efficient manner possible. So far, the best I've come up with is this: $fullString = "ignore everything except this (text)"; $start = strpos('(', $fullStrin...
