• Dictionary as parameter, where the Value-Type is irrelevant

  - by aaginor

  Hi folks, I have a function, that returns the next higher value of a Dictionary-Keys-List compared to a given value. If we have a Key-List of {1, 4, 10, 24} and a given value of 8, the function would return 10. Obviously the type of the Value-Part of the Dictionary doesn't matter for the function, the function-code for a Dictionary<int, int> and Dictionary<int, myClass> would be the same. How has the method-head have to look like, when I want to call the function with any Dictionary, that has int as key-Type and the value-Type is irrelevant? I tried: private int GetClosedKey(Dictionary<int, object> list, int theValue); but it says that there are illegal arguments, when I call it with a Dictionary. I don't want to copy'n'paste the function for each different value-type that my function may be called. Any idea, how to accomplish that? Thanks in advance, Frank

• How to use multiple restrictions in C# Generics properly?

  - by plouh

  I am attempting to bind c# generics to a class and an interface like this: public class WizardPage<T> where T : UserControl, IWizardControl { private T page; public WizardPage( T page ) { this.page = page; } } And use it with this: public MyControl : UserControl, IWizardControl { //... } Somehow C# doesn't seem to be able to decide that MyControl is a proper instance of T as public class Wizard<T> where T : UserControl, IWizardControl { private WizardPage<T> Page1; public Wizard( MyControl control ) { this.Page1 = new WizardPage(control); } } fails with error The best overloaded method match for 'Controls.WizardPage.WizardPage(T)' has some invalid arguments Am I doing something wrong or is this just not going to work?

• Why does the Win32-API have so many custom types?

  - by sub

  I'm new to the Win32 API and the many new types begin to confuse me. Some functions take 1-2 ints and 3 UINTS as arguments. Why can't they just use ints? What are UINTS? Then, there are those other types: DWORD LPCWSTR LPBOOL Again, I think the "primitive" C types would be enough - why introduce 100 new types? This one was a pain: WCHAR* I had to iterate through it and push_back every character to an std::string as there wasn't another way to convert it to one. Horrible. Why WCHAR? Why reinvent the wheel? They could have just used char* instead, or?

• Using a database/index sequential file independently of the Unix distribution

  - by Helper Method

  What I'm planning to do is a) parse a file for some lines matching a regular expression b) store the match in some sort of database / file so I don't have to do the parsing again and again c) call another program passing the matches as arguments While I can imagine how to do a) and c), I'm a little bit unsure about b). The matches are of the form key:attribute1:attribute2:attribute3 where attribute 2 may be optional. I'm thinking of storing the results in a simple database but the problem is the database needs to available on a number of Unix platform for the program to work. Are there any (simple) databases which can be found on any Unix platforms? Or should I use some sort of index-sequential file?

  - by John

  Hi.... This is a exremely stupid question but i need help with this.... I'm trying to make a small program that i made robust and needed some help with tht.... int num1; int num2 = 0; System.out.print("Enter number 1: "); num1 = kb.nextInt(); while(num2<num1) { System.out.print("Enter number 2: "); num2 = kb.nextInt(); } Number 2 has to be greater than number 1 Also i want the program to automatically check and ignore if the user enters a char instead of an int... Cause right now when a user enters lets say "r" instead of a number the program just exists....

• C++ STL: Array vs Vector: Raw element accessing performance

  - by oh boy

  I'm building an interpreter and as I'm aiming for raw speed this time, every clock cycle matters for me in this (raw) case. Do you have any experience or information what of the both is faster: Vector or Array? All what matters is the speed I can access an element (opcode receiving), I don't care about inserting, allocation, sorting, etc. I'm going to lean myself out of the window now and say: Arrays are at least a bit faster than vectors in terms of accessing an element i. It seems really logical for me. With vectors you have all those security and controlling overhead which doesn't exist for arrays. (Why) Am I wrong? No, I can't ignore the performance difference - even if it is so small - I have already optimized and minimized every other part of the VM which executes the opcodes :)

• Any way to not break on certain errors in Visual Studio 2010?

  - by Vulgrin

  I'm working on a VS2010 project where I'm using DataAnnotations on my objects to handle validation. However, this is sort of a pain in the butt while trying to do interactive debugging because it keeps pausing VS.Net on validation errors. Obviously, I want to break on some errors, but not these particular types. Am I out of luck and I just need to turn on and off my Break on All Errors setting? Or is there some way to tell VS to just ignore these when they happen? (these are errors generated via Validator.ValidateProperty calls.) Thanks

• Split SQL statements

  - by eaZy

  Hello, I am writing a backend application which needs to be able to send multiple SQL commands to a MySQL server. MySQL = 5.x support multiple statements, but unfortunately we are interfacing with MySQL 4.x. I am trying to find a way (hint: regex) to split SQL statements by their semicolon, but it should ignore semicolons in single and double quotes strings. http://www.dev-explorer.com/articles/multiple-mysql-queries has a very nice regex to do that, but doesn't support double quotes. I'd be happy to hear your suggestions.

• Theme the node-create and node-edit template

  - by Toxid

  I'm using drupal 6. I've managed to make a .tpl file for one content type, that is for images in my image gallery. I did that by adding this code in template.php: function artbasic_theme($existing, $type, $theme, $path) { return array( 'galleryimage_node_form' => array( 'arguments' => array('form' => NULL), 'template' => 'galleryimage_node_form' ) ); } And then I created galleryimage_node_form.tpl.php, and was good to go. Now it happens so that I want to have other template files for the forms of other content types, for example link_contrib_node_form.tpl.php. I've tried a couple of ways to change this function to include more content types, but I can't figure it out. Can anyone help?

• SQL Select Upcoming Birthdays

  - by Crob

  I'm trying to write a stored procedure to select employees who have birthdays that are upcoming. SELECT * FROM Employees WHERE Birthday > @Today AND Birthday < @Today + @NumDays This will not work because the birth year is part of Birthday, so if my birthday was '09-18-1983' that will not fall between '09-18-2008' and '09-25-2008'. Is there a way to ignore the year portion of date fields and just compare month/days? This will be run every monday morning to alert managers of birthdays upcoming, so it possibly will span new years. Here is the working solution that I ended up creating, thanks Kogus. SELECT * FROM Employees WHERE Cast(DATEDIFF(dd, birthdt, getDate()) / 365.25 as int) - Cast(DATEDIFF(dd, birthdt, futureDate) / 365.25 as int) <> 0

• MySQL, PHP, and Apache errors while connecting to DB

  - by cypherdelton

  I'm having two errors when I test the "mysql_connect()" function in php. I just installed PHP and MySQL from scratch. These errors may be related, so I will post them both here: Warning: mysql_connect() [function.mysql-connect]: Headers and client library minor version mismatch. Headers:50158 Library:50518 in /usr/local/apache2/htdocs/index.php on line 6 Warning: mysql_connect() [function.mysql-connect]: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) in /usr/local/apache2/htdocs/index.php on line 6 Many websites say to start the mysql server if you are getting error #2. Whenever I execute the command mysqld start --user=mysql I get the error "mysqld: Too many arguments (first extra is 'start'); Adding the "&" to the end of the command makes no difference (I don't know if it is supposed to). Thanks, Cypher Delton

• Problem Making C++ script

  - by Abs

  Hello all, I am not sure if I can post this sort of question (apologies in advance) but I am trying to build something from this blog post. # mkdir wkthumb # cat > wkthumb.cpp # qmake -project # qmake && make # ./wkthumb I have no experience with this, but I download all the files needed in the directory wkthumb using git. I have gone inside this directory and tried to execute cat > wkthumb.cpp - this just hangs for me. In addition, I thought cat was supposed to be used like this: cat file1.txt file2.txt > file3.txt? The above is blank with the first arguments? I am using Fedora Core 10.

• What is XML good for and when should i be using it?

  - by Haroldo

  I'm curious, I've been developing pretty powerful websites/web apps, and I've never learnt XML, even odder I've never really felt the need to. It's not like Curl or Prepared Statements where before knowing what they did and how they worked I had a feeling 'there's got to be an easier way to do this!' or 'there's got to be something designed for this!'. Currently I work with MySQL and JSON and I don't have this feeling of 'I need to learn that' (XML), this must be wrong! I'm really interested to hear some compelling arguments for XML, and learn about things which it can do beter than JSON or MySQL (or some other aspect of web dev) and when i should be using it!

• Replace non-html links with <A> tags

  - by tombazza

  I have a block of code that will take a block of text like the following: Sample text sample text http://www.google.com sample text Using the preg_replace_callback method and the following regular expression: preg_replace_callback('/http:\/\/([,\%\w.\-_\/\?\=\+\&\~\#\$]+)/', create_function( '$matches', '$url = $matches[1]; $anchorText = ( strlen($url) > 35 ? substr($url, 0, 35).\'...\' : $url); return \'<a href="http://\'. $url .\'">\'. $anchorText .\'</a>\';'), $str); Will convert the sample text to look like: Sample text sample text < a href="http://www.google.com"http://www.google.com< /a sample text My problem now is that we have introduced a rich text editor that can create links before being sent to the script. I need to update this piece of code so that it will ignore any URLs that are already inside an tag.

• Array-size macro that rejects pointers

  - by nneonneo

  The standard array-size macro that is often taught is #define ARRAYSIZE(arr) (sizeof(arr) / sizeof(arr[0])) or some equivalent formation. However, this kind of thing silently succeeds when a pointer is passed in, and gives results that can seem plausible at runtime until things mysteriously fall apart. It's all-too-easy to make this mistake: a function that has a local array variable is refactored, moving a bit of array manipulation into a new function called with the array as a parameter. So, the question is: is there a "sanitary" macro to detect misuse of the ARRAYSIZE macro in C, preferably at compile-time? In C++ we'd just use a template specialized for array arguments only; in C, it seems we'll need some way to distinguish arrays and pointers. (If I wanted to reject arrays, for instance, I'd just do e.g. (arr=arr, ...) because array assignment is illegal).

• How do I convert a number (as a String) to an array of bytes in Java?

  - by user1795595

  I'm creating a method specific method for a java project i'm working on. The UML given specifies the return type to be of static byte[] that accepts the arguments (String, byte) So far, looks like this: public static byte[] convertNumToDigitArray(String number, byte numDigits) { } This method is supposed to convert a number (as a String) to an array of bytes. The ordering must go from most to least significant digits. For example, if the number String is “732” then index 0 of the array should contain 7. The last argument (numDigits) should match the length of the string passed in. How do I do this?

• the problem of redirecting stdout in c#

  - by Mher

  Could you please explain why the shell redirection doesn't work with System.Diagnostics.Process class? I am trying to redirect the output streams to file with the following snippet: Process p = new Process(); p.StartInfo = new ProcessStartInfo(); p.StartInfo.FileName = "java.exe"; p.StartInfo.Arguments = @"> c:\Temp\test.log 2>&1"; p.StartInfo.UseShellExecute = true; p.Start(); The similar code works without problems with Python. Reading the output streams programmatically doesn't seem a preferable solution in my case because there will be a bunch of processes launched by my application.

• MySQL Query : Advise Needed.

  - by Rachel

  "SELECT id as Id from dbTable WHERE code = ?

• PHP, better to set the variable before if or use if/else?

  - by DssTrainer

  So a simple one that I just never could find a straight answer on. What is better (performance or otherwise): $var = false; If ($a == $b) { $var = true; } or If ($a == $b) { $var = true; } else { $var = false; } I've heard arguments for both ways. I find the first cleaner to ensure I have it set, and a little less code too. The pro being that you may only need to set it once without conditional. But the con being that if the argument is true, it gets set twice. I am assuming the second way is probably best practice

• What's the difference between => , ()=>, and Unit=>

  - by Malvolio

  I'm trying to represent a function that takes no arguments and returns no value (I'm simulating the setTimeout function in JavaScript, if you must know.) case class Scheduled(time : Int, callback : => Unit) doesn't compile, saying " `val' parameters may not be call-by-name" case class Scheduled(time : Int, callback : () => Unit) compiles, but has to be invoked strangely, instead of Scheduled(40, { println("x") } ) I have to do this Scheduled(40, { () => println("x") } ) What also works is class Scheduled(time : Int, callback : Unit => Unit) but is invoked in an even-less-sensible way Scheduled(40, { x : Unit => println("x") } ) (What would a variable of type Unit be?) What I want of course is a constructor that can be invoke the way I would invoke it if it were an ordinary function: Scheduled(40, println("x") ) Give baby his bottle!

• How to do a random-and-unique generator?

  - by javaLearner.java

  I already wrote a random generator which take arguments a and b, where a is minimun and b is maximum value, like this randomGenerator(int a, int b) What I want to do next is: Using a loop, then generate unique number from a to b. Example: I want to have 8 unique numbers, int a = 1; int b = 10; int value; If I do the loop, there is a high % that same number will appear more than once. Any idea how to do it? My own way is: while(int i <= 8){ randomGenerator(a,b); // if value is not in array, then insert into array } I am stuck at the comment part. Is there any way to check if a variable is exists in an array?

• Problem with Nulls and an UPDATE statement

  - by Dave

  UPDATE TableA SET Value = a.Value * b.AnotherValue FROM TableA AS a INNER JOIN TableB AS b WHERE (Condition is true); Here is the problem. The Value field for TableA does not allow nulls. If the calculation of a.Value * b.AnotherValue yields a null, an error is thrown. Now the question. Is there any way to tell the UPDATE to ignore the SET phase when the result of the calculation is a null and delete the record rather than updating it. This UPDATE is intended to update hundreds of records at a time but will fail if a single null is encountered. Also, please note that using the ISNULL() function and setting the Value to zero is not acceptable. I would like the record to be dropped if a null is encountered. Many thanks in advance for any help rendered.
