• Visual Basic 2013 String Replacement

  - by user3707612

  I found this code that replaces a string in a text file. But, I am trying to make it so that it replaces several strings in a text file. My.Computer.FileSystem.WriteAllText("C:\windows\PrinterList2.txt", My.Computer.FileSystem.ReadAllText("C:\windows\PrinterList.txt").Replace("IT", "ADM-IT"), False) For example, I need it to replace "IT" with "ADM-IT" and "AR" with "ADM-AR" and possibly a hundred or so more. How can I get it to loop to do them all? Running this line of code over and over just overwrites the file with the last item for replacement. Thanks in advance.

• How to create simpliest PHP Get API with UTF-8 support?

  - by Ole Jak

  How to create simpliest *(less lines of code, less strange words) PHP Get API *(so any programm made in .Net C# could call url like http://localhost/api.php?astring=your_utf-8_string&bstring=your_utf-8_string ) with UTF-8 support? What I need Is PHP API with one function - concatinate 2 strings so that a simple .net client like this would be able to use it: public string setStream(string astring, string bstring) { string newAstring =Uri.EscapeDataString(astring); string newBstring = Uri.EscapeDataString(bstring); WebClient client = new WebClient(); var result = client.DownloadString(("http://localhost/api.php?" + string.Format("astring={0}&bstring={1}", newAstring, newBstring)).ToString()); return result; }

• WPF/C# - Sometimes my dropdowns/datepickers will stop functioning?

  - by BlargINC

  Q: Where should I check to track this down? Issue: Opening a view model in my application sometimes makes dropdowns/datepickers nonfunctional. ie. dropdown won't drop and the datepicker calendar won't come up I suspect a binding issue but don't see one. Dropdowns have normal things like strings, numbers. One drop has a list of mini views. Datepickers are bound to nullable dates set in the constructor of the viewmodel. Note: These same things work in other viewmodels/views. I can paste code, I'm just not sure what code is relevant here. Thank you for helping me :)

• Parsing through Arabic / RTL text from left to right

  - by Dan W

  Let's say I have a string in an RTL language such as Arabic with some English chucked in: string s = "Test:?????;?????;?????;a;b" Notice there are semicolons in the string. When I use the Split command like string[] spl = s.Split(';');, then some of the strings are saved in reverse order. This is what happens: ??Test:????? ????? ????? a b The above is out of order compared to the original. Instead, I expect to get this: ?Test: ????? ????? ????? a b I'm prepared to write my own split function. However, the chars in the string also parse in reverse order, so I'm back to square one. I just want to go through each character as it's shown on the screen.

• Ruby (with Rails) convert a string of time into seconds?

  - by Ryan

  So, I've got a string of time... something along the lines of '4 hours' '48 hours' '3 days' '15 minutes' I would like to convert those all into seconds. For '4 hours', this works fine Time.parse('4 hours').to_i - Time.prase('0 hours').to_i => 14400 # 4 hours in seconds, yay However, this doesn't work for 48 hours (outside of range error). It also does not work for 3 days (no information error), etc. Is there a simple way to convert these strings into seconds?

• Regular Expression

  - by equilibrium

  Ohh! this regular expression thing is eating my brain up. I have been reading it from Introduction to Automata Theory, Languages and Computer by Hopcroft, Motwani and Ullman. I have solved a few exercises too but could not solve the following even after trying for almost one hr. The problem is to write a regular expression that defines a language consisting of all strings of 0s and 1s except the substring 011. Is the answer (0+1)* - 011 correct ? If not what should be the correct answer for this?

• compare two characters based on subset

  - by schultem

  I have a simple dataframe with two columns: df <- data.frame(x = c(1,1,2,2,3), y = c(rep(1:2,2),1), target = c('a','a','a','b','a')) I would like to compare the strings in the target column (find out whether they are equal or not, i.e., TRUE or FALSE) within every level of x (same number for x). First I would like to compare lines 1 and 2, then 3 and 4 ... My problem is that I am missing some comparisons, for example, line 5 has only one case instead of two - so it should turn out to be FALSE. Variable y indicates the first and second case within x. I played around with ddply doing something like: ddply(df, .(x), summarise, ifelse(as.character(df[df$y == '1',]$target), as.character(df[df$y == '2',]$target),0,1)) which is ugly ... and does not work ... Any insights how I could achieve this comparison? Thanks

• what is regular expression not generated over {a,b}?

  - by Loop

  Hello all, I am really stuck with these 2 question for over 2 days now. trying to figure out what the question means.... my tutor is out of town too.... write a regular expression for the only strings that are not generated over {a,b} by the expression: (a+b)*a(a+b)*. explain your reasoning. and i tried the second question, do you think is there any better answer than this one? what is regular expression of set of string that contain an odd number of a's or exactly two b's................(a((a|b)(a|b))*|bb).... coz i know to represent any odd length of a's, the RE is a((a|b)(a|b))*

• Is it possible to achieve string localization inside of a statically linked lib?

  - by user3696003

  I am working on building an SDK which will be built out as a statically linked library that third party applications can then drop in to their applications. Inside of this SDK, I was looking to be able to perform some "localization." Basically, I would like for the code in my SDK to be able to access some ".string" files to perform some string lookup and language translation capabilities. Then I could propagate these strings outward to implementing App layers through my exposed API's. Is this even possible? I thought it was but now that I have actually been trying, I am seriously having doubts.

• Which MySQL Datatype to use for storing boolean values from/to PHP?

  - by Beat

  Since MySQL doesn't seem to have any 'boolean' datatype, which datatype do you 'abuse' for storing true/false information in MySQL? Especially in the context of writing and reading from/to a PHP-Script. Over time I have used and seen several approaches: tinyint, varchar fields containing the values 0/1, varchar fields containing the strings '0'/'1' or 'true'/'false' and finally enum Fields containing the two options 'true'/'false'. None of the above seems optimal, I tend to prefer the tinyint 0/1 variant, since automatic type conversion in PHP gives me boolean values rather simply. So which datatype do you use, is there a type designed for boolean values which I have overlooked? Do you see any advantages/disadvantages by using one type or another?

• How do I create substrings from an array using PHP?

  - by mike

  I have an array of data that looks like this: 2008, Honda, Accord, Used, Car And I'm trying to figure a way to make a number of sub strings from each item in the array. For example, I would like to loop each item and create the following substrings: 2008 2008 Honda 2008 Accord 2008 Used 2008 Car 2008 Honda Accord 2008 Honda Used 2008 Honda Car 2008 Accord Honda 2008 Accord Used 2008 Accord Car 2008 Used Honda 2008 Used Accord 2008 Used Car 2008 Car Honda 2008 Car Accord 2008 Car Used Honda Honda 2008 Honda Accord Honda Used Honda Car Honda 2008 Accord Honda 2008 Used etc ... I need to make sure that there are no duplicates created and I need to prevent it from adding the same word twice (ex: Honda Honda OR 2008 Honda 2008 - i dont want that). Has anyone wrote anything like this or know where I can find a script that works the same way?

• SQL - logical AND among multiple rows

  - by potrnd

  Hello, First of all sorry that I could not think of a more descriptive title. What I want to do is the following using only SQL: I have some lists of strings, list1, list2 and list3. I have a dataset that contains two interesting columns, A and B. Column A contains a TransactionID and column B contains an ItemID. Naturally, there can be multiple rows that share the same TransactionIDs. I need to catch those transactions that have at least one item ID that exists whithin each list (list1, list2 AND list3). I also need to count how many times does that happen for each transaction. I hope that makes enough sense, perhaps I will be able to explain it better with a clear head. Thanks in advance

• In Django, using __init__() method of non-abstract parent model to record class name of child model

  - by k-g-f

  In my Django project, I have a non-abstract parent model defined as follows: class Parent(models.Model): classType = models.CharField(editable=False,max_length=50) and, say, two children models defined as follows: class ChildA(Parent): parent = models.OneToOneField(Parent,parent_link=True) class ChildB(Parent): parent = models.OneToOneField(Parent,parent_link=True) Each time I create an instance of ChildA or of ChildB, I'd like the classType attribute to be set to the strings "ChildA" or "ChildB" respectively. What I have done is added an _ _ init_ _() method to Parent as follows: class Parent(models.Model): classType = models.CharField(editable=False,max_length=50) def __init__(self,*args,**kwargs): super(Parent,self).__init__(*args,**kwargs) self.classType = self.__class__.__name__ Is there a better way to implement and achieve my desired result? One downside of this implementation is that when I have an instance of the Parent, say "parent", and I want to get the type of the child object linked with "parent", calling "parent.classType" gives me "Parent". In order to get the appropriate "ChildA" or "ChildB" value, I need to write a "_getClassType()" method to wrap a custom sql query.

• Which substring of the string1 matches with the string2.

  - by Harikrishna

  There are two strings. String str1="Order Number Order Time Trade Number"; String str2="Order Tm"; Then I want to know that str2 matches with which substring in the str1. string regex = Regex.Escape(str2.Replace(@"\ ", @"\s*"); bool isColumnNameMatched = Regex.IsMatch(str1, regex, RegexOptions.IgnoreCase); I am using regex because "Order Tm" will also matches "Order Time".It gives bool value that matches occurred or not. Like str2="Order Tm" then it should return like in the str1,Order Time is the substring where matches is occurred.

• In Perl, is there a built in way to compare two arrays for equality?

  - by Bill

  I have two arrays of strings that I would like to compare for equality: my @array1 = ("part1", "part2", "part3", "part4"); my @array2 = ("part1", "PART2", "part3", "part4"); Is there a built-in way to compare arrays like there is for scalars? I tried: if (@array1 == @array2) {...} but it just evaluated each array in scalar context, and so compared the length of each array. I can roll my own function to do it, but it seems like such a low-level operation that there should be a built-in way to do it. Is there? Edit: sadly, I don't have access to 5.10+ or optional components.

• Creating methods with infinite overloads ? (.NET)

  - by MarceloRamires

  In C# you can do this: foo = string.Format("{0} {1} {2} {3} ...", "aa", "bb", "cc" ...); This method Format() accepts infinite parameters, being the first one how the string should be formatted and the rest are values to be put in the string. Today I've come to a situation where I had to get a set of strings and test them, then I remembered this language functionality, but I had no clue. After a few unsuccessful web searches, I've realised it would be more prudent to just get an array, which didn't make me quite satisfied. Q: How do I make a function that accepts infinite parameters? And how do I use it ?
