  • Sending string from class to Form1

    - by Farstucker
    Although there are some similar questions I’m having difficulties finding an answer on how to receive data in my form from a class. I have been trying to read about instantiation and its actually one of the few things that does make sense to me :) but if I were to instantiate my form, would I not have two form objects? To simplify things, lets say I have a some data in Class1 and I would like to pass a string into a label on Form1. Is it legal to instantiate another form1? When trying to do so it looks like I can then access label1.Text but the label isn’t updating. The only thing I can think of is that the form needs to be redrawn or there is some threading issue that I’m unaware of. Any insight you could provide would be greatly appreciated.

  • Can't append space at end of NSString

    - by Sam V
    I have a UITextView in which I want the initial value to be "@username " (notice the space after the username). This way the user can start typing right away without having to tap space. So I do: textView.text = [NSString stringWithFormat:@"@%@ ", username]; But it seems like it's impossible to have an NSString ending with a space (it always gets stripped out). Am I correct? Is there any workaround for this?

  • How to remove the file extension in a zsh completion?

    - by meeselet
    I want to adjust zsh so that I can tab complete: myprog <tab> using all *.foo files in ~/somedir, but have it so that it displays them without the .foo extension. Is there any way to do this? This is what I have so far: #compdef myprog typeset -A opt_args local context state line local -a mydirs mydirs="(. ~/somedir)" _arguments -s -S \ "*:name:->foos" \ && return 0 case $state in (foos) _files -W ${mydirs} -g '*.foo(:r)' && return 0 ;; esac return 1 However, this displays double the output for every file (that is, each .foo file is listed with and without its extension). Is there any way around this?

  • Delphi - Differences between CompareStr and CompareString

    - by Bourgui
    Hi all, I'm hoping someone can shed some light on this for me What are the differences, in Delphi 2009, between the CompareStr (defined in SysUtils) and CompareString (from Windows API) functions? Both let you specify the locale to be used, is the Windows one simply more "complete", due to the available comparison flags? Is one consequently faster than the other? Thanks!

  • string parsing help

    - by sprugman
    I've got a string like this: #################### Section One #################### Data A Data B #################### Section Two #################### Data C Data D etc. I want to parse it into something like: $arr( 'Section One' => array('Data A', 'Data B'), 'Section Two' => array('Data C', 'Data D') ) At first I tried this: $sections = preg_split("/(\r?\n)(\r?\n)#/", $file_content); The problem is, the file isn't perfectly clean: sometimes there are different numbers of blank lines between the sections, or blank spaces between data rows. The section head pattern itself seems to be relatively consistent: #################### Section Title #################### The number of #'s is probably consistent, but I don't want to count on it. The white space on the title line is pretty random. Once I have it split into sections, I think it'll be pretty straightforward, but any help writing a killer reg ex to get it there would be appreciated. (Or if there's a better approach than reg ex...)

  • What is the safest way to pass strings around in C?

    - by chucknelson
    I have a program in C using Solaris with VERY ancient compatibility it seems. Many examples, even here on SO, don't work, as well as lots of code I've written on Mac OS X. So when using very strict C, what is the safest way to pass strings? I'm currently using char pointers all over the place, due to what I thought was simplicity. So I have functions that return char*, I'm passing char* to them, etc. I'm already seeing strange behavior, like a char* I passed having its value right when I enter a function, and then the value being mysteriously gone OR corrupted/overwritten after something simple like one printf() or an malloc to some other pointer. I was thinking maybe declaring a local char[] inside each function, using strcpy() immediately, and then eventually returning a pointer where char *returnval = strdup(localchar[]); This seems...sloppy. Can anyone point me in the right direction on a simple requirement?

  • C++ visitor pattern handling templated string types?

    - by Steve the Plant
    I'm trying to use the visitor pattern to serialize the contents of objects. However one snag I'm hitting is when I'm visiting strings. My strings are of a templated type, similar to STL's basic_string. So something like: basic_string<char_type, memory_allocator, other_possible_stuff> \\ many variations possible! Since I can have very many different templated string types, I can't go and add them to my visitor interface. It would be ridiculous. But I can't add templates to my VisitString method because C++ prevents using templates parameters in virtual methods. So what are my options to work around this?

  • Overloading operator>> for case insensitive string

    - by TheSOFan
    Given the definition of ci_string from cpp.reference.com, how would we go about implementing operator? My attempts at it involved std::read, but it doesn't seem to work (that is, gcount() properly counts the number of characters entered, but there is no output) #include <iostream> #include <cctype> #include <string> // ci_string definition goes here std::istream& operator>>(std::istream& in, ci_string& str) { return in.read(&*str.begin(), 4); } int main() { ci_string test_str; std::cin >> test_str; std::cout << test_str; return 0; }

  • Powershell's import-clixml from string

    - by rocku
    Is there any way to run import-clixml cmdlet on a string or xml object? It requires a file path as input to produce ps objects and can't get input from an xml object. Since there is convertto-xml cmdlet which serializes ps object into xml object, why isn't there a convertfrom-xml, which would do the opposite? I am aware of System.Xml.Serialization.XmlSerializer class which would do just that, however I would like to stick with cmdlets to do this. Is there any way to do this with cmdlets (probably just with import-clixml), without creating temporary files?

  • Using strtok() in a loop in C?

    - by Alex Xander
    I am trying to use strtok() in nested loop. But this is not giving me desired results. Possibly because they are using same memory location. My code is of the form:- char *token1 = strtok(Str1, "%"); while(token1 != NULL ) { char *token2 = strtok(Str2, "%"); while(token2 != NULL ) { //DO SMTHING token2 = strtok(NULL, "%"); } token1 = strtok(NULL, "%"); // Do something more }

  • String.fromCharCode & CharacterSets

    - by jAndy
    Hi Folks, I recently tried to mirror some input within input(text) fields. Using String.fromCharCode(event.which) for instance, translates all 'standard' characters correctly. Well it translates them all to uppercase, but that you can easily catch by looking up the shift key aswell. My Problem is, it can't translate characters like dots, commas, questionmarks etc. First guess was that I have to define a character encoding set, but that does not seem to help. Maybe it'm completly off? Kind Regards --Andy

  • Can't append to array using string field name [$] when performing update on array fields

    - by Haraldo
    rowsI am attempting to perform a mongodb update on each field in an array of records. An example schema is below: { "_id" : ObjectId("508710f16dc636ec07000022"), "summary" : "", "uid" : "ABCDEF", "username" : "bigcheese", "name" : "Name of this document", "status_id" : 0, "rows" : [ { "score" : 12, "status_id" : 0, "uid" : 1 }, { "score" : 51, "status_id" : 0, "uid" : 2 } ] } So far I have been able to perform single updates like this: db.mycollection.update({"uid":"ABCDEF","rows.uid":1}, {$set:{"rows.$.status_id":1}},false,false) However, I am struggling as to how to perform an update that will update all array records to a status_id of 1 (for instance). Below is how I imagine it should work: db.mycollection.update({"uid":"ABCDEF"}, {$set:{"rows.$.status_id":1}},false,true) However I get the error: can't append to array using string field name [$] I have tried for quite a while with no luck. Any pointers?

  • I'm looking for a constraint to prevent the insert of an empty string in MySQL

    - by Marga Keuvelaar
    Ok, in this question I learned how to prevent the insert of a NULL value. But, unfortunately, an empty string is being inserted anyway. Apart from preventing this on the PHP side, I'd like to use something like a database constraint to prevent this. Of course a check on the application side is necessary, but I'd like it to be on both sides. I am taught that whatever application is talking to your database, it should not be able to insert basically wrong data in it. So... CREATE TABLE IF NOT EXISTS tblFoo ( foo_id int(11) NOT NULL AUTO_INCREMENT, foo_test varchar(50) NOT NULL, PRIMARY KEY (foo_id) ); Would still allow me to do this insert: INSERT INTO tblFoo (foo_test) VALUES (''); Which I would like to prevent.

  • Non-string role names in ASP.NET MVC?

    - by MikeWyatt
    ASP.NET MVC has good support for role-based security, but the usage of strings as role names is maddening, simply because they cannot be strongly-typed as enumerations. For example, I have an "Admin" role in my app. The "Admin" string will now exist in the Authorize attribute of my action, in my master page (for hiding a tab), in my database (for defining the roles available to each user), and any other place in my code or view files where I need to perform special logic for admin or non-admin users. Is there a better solution, short of writing my own authorization attribute and filter, that would perhaps deal with a collection of enumeration values?

  • Apache rewrite_mod: RewriteRule path and query string

    - by 1ace
    I currently have a website with a standard web interface on index.php, and I made an iPhone-friendly version in iphone.php. Both pages handle the same arguments. It works fine when I manually go to .../iphone.php, but I'd like to rewrite anything on .../path/ and .../path/index.php to iphone.php if %{HTTP_USER_AGENT} contains mobile, and optionally add the query string (not sure if/when I'd need to add it). So far, this is what I have in my .../path/.htaccess: RewriteEngine On RewriteCond %{HTTP_USER_AGENT} ^.+mobile.+$ [NC] RewriteRule index.php?(.*) iphone.php?$1 [L] RewriteRule index.php iphone.php [L] The problems are, it matches index.php in any subfolder, and it won't match .../path/?args… Special thanks to anyone who can correct/simplify/optimize anything =)

  • Regex to get rid of everything past the first sentence in a string in php

    - by andufo
    I need to get rid of everything after the first dot (if there is more than 1 sentence), but at the same time, cases like e.g. have to be omited. Some line e.g., when people do something. Extra content. Some line (some parenthesis). Extra content. I need to get rid of the "Extra content.". The returning value should be: Some line e.g., when people do something. Some line (some parenthesis). So far I've come with this regex taken from other threads, but it only finds the dots and split the string into an array. preg_replace('/(?<!\.)\.(?!(\s|$|\,|\w\.))/','',$text); Any ideas? Thanks.

  • Use stringWithFormat: as a file path in cocoa

  • Python unicode search not giving correct answer

    - by user1318912
    I am trying to search hindi words contained one line per file in file-1 and find them in lines in file-2. I have to print the line numbers with the number of words found. This is the code: import codecs hypernyms = codecs.open("hindi_hypernym.txt", "r", "utf-8").readlines() words = codecs.open("hypernyms_en2hi.txt", "r", "utf-8").readlines() count_arr = [] for counter, line in enumerate(hypernyms): count_arr.append(0) for word in words: if line.find(word) >=0: count_arr[counter] +=1 for iterator, count in enumerate(count_arr): if count>0: print iterator, ' ', count This is finding some words, but ignoring some others The input files are: File-1: ???? ??????? File-2: ???????, ????-???? ?????-???, ?????-???, ?????_???, ?????_??? ????_????, ????-????, ???????_???? ????-???? This gives output: 0 1 3 1 Clearly, it is ignoring ??????? and searching for ???? only. I have tried with other inputs as well. It only searches for one word. Any idea how to correct this?
