• Override l() function in Drupal

  - by Marco

  I'm currently working on a Drupal site (6.*), which when in production mode will be accessed through some kind of http proxy, which means I will have to rewrite all the links for my custom theme if the $_SERVER['HTTP_X_FORWARDED_SERVER'] variable is set to the domain people will access the site from. The site has a lot of internal linking, mostly through Views. My thought is that the easiest way to solve this would be to hook into the url() and/or the l() functions and post process the url before returning it if HTTP_X_FORWARDED_SERVER is set. My problem is that I can't figure out how to hook into these functions, or if it's even possible without touching the core, has anyone had to do this? How did you solve it?

• How do I parse a templated string in Python?

  - by mLewisLogic

  I'm new to Python, so I'm not sure exactly what this operation is called, hence I'm having a hard time searching for information in it. Basically I'd like to have a string such as: "[[size]] widget that [[verb]] [[noun]]" Where size, verb, and noun are each a list. I'd like to interpret the string as a metalanguage, such that I can make lots of sentences out permutations from the lists. As a metalanguage, I'd also be able to make other strings that use those pre-defined lists to generate more permutations. Are there any capabilities for variable substitution like this in Python? What term describes this operation if I should just Google it?

• Check user authentication at page load

  - by Shrewd Demon

  ok i have another question ! (god! i have so many questions) i have an application and a user must log-in before he/she can access pages. now once the user logs in i keep the user details in a session variable (say Session["CurrentUser"]). now if a user tries to jump to a page directly i will check if the Session["CurrentUser"] has a value or not...if not then the user will be directed to the login page... my problem is that i have done this or rather say written this "Checking Code" on almost all the pages. what i want is this code to stay on a particular location and i will just access that method all the time on all the pages...now where should i write this method ?? thank you.

• Cant free memory.

  - by atch

  In code: int a[3][4] = {1,2,3,4, 5,6,7,8, 9,10,11,12}; template<class T, int row, int col> void invert(T a[row][col]) { T* columns = new T[col]; T* const free_me = columns; for (int i = 0; i < col; ++i) { for (int j = 0; j < row; ++j) { *columns = a[j][i]; ++columns;//SOMETIMES VALUE IS 0 } } delete[] free_me;//I'M GETTING ERROR OF HEAP ABUSE IN THIS LINE } int main(int argc, char* argv[]) { invert<int,3,4>(a); } I've observed that while iterating, value of variable columns equals zero and I think thats the problem. Thanks for your help.

• I have to generate PL/SQL using Java. Most of the procedures are common. Only a few keeps changing.

  - by blog

  I have to generate PL-SQL code, with some common code(invariable) and a variable code. I don't want to use any external tools. Some ways that I can think: Can I go and maintain the common code in a template and with markers, where my java code will generate code in the markers and generate a new file. Maintain the common code in static constant String and then generate the whole code in StringBuffer and at last write to file. But, I am not at all satisfied with both the ideas. Can you please suggest any better ways of doing this or the use of any design patterns or anything? Thanks in Advance.

• how to remove trailing and leading whitespace for user-provided input in dos?

  - by OopOop

  I know how to do this when the variable is pre-defined. However, when asking for the user to enter in some kind of input, how do I trim leading and trailing whitespace? This is what I have so far: @echo off set /p input=: echo. The input is %input% before ::trim left whitespace for /f "tokens=* delims= " %%a in ("%input%") do set input=%%a ::trim right whitespace (up to 100 spaces at the end) for /l %%a in (1,1,100) do if "!input:~-1!"==" " set input=!input:~0,-1! echo. The input is %input% after pause Thank you! :)

'"'; } else $mInput = "null"; return $mInput; } I have a string "0004", which is going in a "varchar field", is cought by is_numeric, and is saved as "4" and not "0004". Is there a way to detect the padding and process it as a string? Thank you!

• What to do with twitter oauth token once retreived?

  - by mcintyre321

  I'm writing a web app that will use twitter as its primary log on method. I've written code which gets the oauth token back from Twitter. My plan is now to Find the entry in my Users table for the twitter username retreived using the token, or create the entry if necessary Update the Users.TwitterOAuthToken column with the new OAuth token Create a permanent cookie with a random guid on the site and insert a record into my UserCookies table matching Cookie to User when a request comes in I will look for the browser cookie id in the UserCookies table, then use that to figure out the user, and make twitter requests on their behalf Write the oauth token into some pages as a js variable so that javascript can make requests on behalf of the user If the user clears his/her cookies the user will have to log in again to twitter Is this the correct process? Have I created any massive security holes? thanks!

• ASP, My SQL & case sensitity suddenly broken

  - by user131812

  Hi There, We have an old ASPsite that has been working fine for years with a MY SQL database. All of a sudden last week lots fo SQL queries stopped working. The database has a table called 'members' but the code calls 'Members'. It appears the queries used to work regardless of case sensitivity on the table names, but something has changed recently somewhere to enforce case. This has me stumped as the site has not been touched in years, the server config hasn't changed & the database provide has not changed anything. Is there any simple way to ignore case for an ASP site (without editing lots fo files :) Thanks Ben

• Grails - Need to restrict fetched rows based on condition on join table

  - by sector7

  Hi guys, I have these two domains Car and Driver which have many-to-many relationship. This association is defined in table tblCarsDrivers which has, not surprisingly, primary keys of both the tables BUT additionally also has a new boolean field deleted. Herein lies the problem. When I find/get query on domain Car, I am fetched all related drivers irrespective of their deleted status in tblCarsDrivers, which is expected. I need to put a clause/constraint to exclude the deleted drivers from the list of fetched records. PS: I tried using an association domain CarDriver in joinTable name but that seems not to work. Apparently it expects only table names, not maps. PPS: I know its unnatural to have any other fields besides the mapping keys in mapping table but this is how I got it and it cant be changed. Car domain is defined as such - class Car { Integer id String name static hasMany = [drivers:Driver] static mapping = { table 'tblCars' version false drivers joinTable:[name: 'tblCarsDrivers',column:'driverid',key:'carid'] } } Thanks!

• Iterator in Java.

  - by theband

  What is Iterator and collections? Does these two have any relations? // the interface definition Interface Iterator { boolean hasNext(); Object next(); // note "one-way" traffic void remove(); } // an example public static void main (String[] args){ ArrayList cars = new ArrayList(); for (int i = 0; i < 12; i++) cars.add (new Car()); Iterator it = cats.iterator(); while (it.hasNext()) System.out.println ((Car)it.next()); } Does the Interface Iterator has these method names alone predefined or its user defined?. What does these four lines below actually tell? cars.add (new Car()); Iterator it = cats.iterator(); while (it.hasNext()) System.out.println ((Car)it.next()); Thanks i am going through a book in collections.

• Using locks inside a loop

  - by Xaqron

  // Member Variable private readonly object _syncLock = new object(); // Now inside a static method foreach (var lazyObject in plugins) { if ((string)lazyObject.Metadata["key"] = "something") { lock (_syncLock) { if (!lazyObject.IsValueCreated) lazyObject.value.DoSomething(); } return lazyObject.value; } } Here I need synchronized access per loop. There are many threads iterating this loop and based on the key they are looking for, a lazy instance is created and returned. lazyObject should not be created more that one time. Although Lazy class is for doing so and despite of the used lock, under high threading I have more than one instance created (I track this with a Interlocked.Increment on a volatile shared int and log it somewhere). The problem is I don't have access to definition of Lazy and MEF defines how the Lazy class create objects. My questions: 1) Why the lock doesn't work ? 2) Should I use an array of locks instead of one lock for performance improvement ?

• UILabel with custom font displays *wrong* custom font

  - by winsmith

  I'm using this method to embed custom fonts in my iPhone app. The embedding works: When I run the following code, the fonts are listed. (Currently, I'm embedding all family members of Myriad Pro in OTF format) for( NSString *familyName in [UIFont familyNames] ){ for( NSString *fntName in [UIFont fontNamesForFamilyName:familyName] ){ NSLog(@"%@", fntName); }} When I try to set the font of a label to MyriadPro or MyriadPro-Bold, this works just as expected. However, when I set the font to MyriadPro-BoldCond, the label is still set in MyriadPro-Bold instead of the condensed version. (The font names are correct, I checked.) My Code: [recommendationLabel setFont:[UIFont fontWithName:@"MyriadPro-BoldCond" size:140]]; recommendationLabel.adjustsFontSizeToFitWidth = YES; What's the deal?

• How to make form validation in Django dynamic?

  - by Oli

  I'm trying to make a form that handles the checking of a domain: the form should fail based on a variable that was set earlier in another form. Basically, when a user wants to create a new domain, this form should fail if the entered domain exists. When a user wants to move a domain, this form should fail if the entered domain doesn't exist. I've tried making it dynamic overload the initbut couldn't see a way to get my passed variabele to the clean function. I've read that this dynamic validation can be accomplished using a factory method, but maybe someone can help me on my way with this? Here's a simplified version of the form so far: #OrderFormStep1 presents the user with a choice: create or move domain class OrderFormStep2(forms.Form): domain = forms.CharField() extension = forms.CharField() def clean(self): cleaned_data = self.cleaned_data domain = cleaned_data.get("domain") extension = cleaned_data.get("extension") if domain and extension: code = whoislookup(domain+extension); #Raise error based on result from OrderFormStep1 #raise forms.ValidationError('error, domain already exists') #raise forms.ValidationError('error, domain does not exist') return cleaned_data

• Populating a WPF listbox with items from an SQL (SDF) database

  - by xplinux557

  I have been searching on how to do this for a very long time, and I have not managed to get a straight answer on the subject, so hopefully one of you StackOverflow users will be able to help me here. I have a WPF ListBox named CategoryList and a SDF database called ProgramsList.sdf (with two tables called CategoryList and ProgramsList). What I wish my program to do is get the category names from the CategoryList table and list them in the ListBox control called CategoryList. Here's the code that I tried, but it only caused my program to crash. SqlConnection myConnection = new SqlConnection("Data Source=" + AppDomain.CurrentDomain.BaseDirectory + "ProgramsList.sdf"); SqlDataReader myReader = null; myConnection.Open(); CategoryList.Items.Clear(); SqlDataReader dr = new SqlCommand("SELECT Name FROM CategoryList ORDER BY Name DESC", myConnection).ExecuteReader(); while (myReader.Read()) { CategoryList.Items.Add(dr.GetInt32(0)); } myConnection.Close(); Can anyone help me? Thanks in advance!

• Binding to object properties in C++

  - by Rich.Carpenter

  I've seen in WPF where you can bind control values to properties of other controls. How is that binding accomplished in C++? For example, if I have a class called Car and a guage control called RPM, how do I tie the value of RPM to the member variable Car.RPM, so that when Car.RPM changes, it is automatically (as in without a specific update call coded by me) reflected by the RPM control? General answers or directions to pertinent resources would be fine also, as I'm just beginning to dabble in C++ and haven't had much Google luck with this particular question.

• I'm having a hard time wrapping my head around handling the Activity Lifecycle...

  - by kefs

  So it seems i've created a fatal flaw and coded an app before understanding/handling rotation/lifecycle events.. Currently, all of my code is in onCreate of each activity. I've read a lot of lifecycle tutorials online, including the official dev guide info, but i'm still having an almost unbelievably hard time trying to wrap my head around the rotation/lifecycle events/methods and when to use them correctly. For example, my app currently has an activity that opens the db, inserts a record, then closes the db.. if i rotate my screen on this activity, the data is re-entered into the db. Using the available lifecycle events (onPause(), onResume(), etc..), how would I prevent this db call from happening again? Would I have to pass a variable through the state saying that the db call has been done, and not to do it again? Thanks in advance..

• Setting precision on std::cout in entire file scope - C++ iomanip

  - by Ivan

  Hi all, I'm doing some calculations, and the results are being save in a file. I have to output very precise results, near the precision of the double variable, and I'm using the iomanip setprecision(int) for that. The problem is that I have to put the setprecision everywhere in the output, like that: func1() { cout<<setprecision(12)<<value; cout<<setprecision(10)<<value2; } func2() { cout<<setprecision(17)<<value4; cout<<setprecision(3)<<value42; } And that is very cumbersome. Is there a way to set more generally the cout fixed modifier? Thanks

• Creating parameterized type object using annonymous class

  - by Andrei Fierbinteanu

  This might be a stupid question, but I just saw a question asking how to create a Type variable for a generic type. The consensus seemed to be that you should have a dummy method returning that type, and then use reflection to get it (in this case he wanted Map<String, String>). Something like this : public Map<String, String> dummy() { throw new Error(); } Type mapStringString = Class.forName("ThisClass").getMethod("dummy").getGenericReturnType(); My question is, not having used reflection that much, couldn't you just do something like: Type mapStringString = new ParameterizedType() { public Type getRawType() { return Map.class; } public Type getOwnerType() { return null; } public Type[] getActualTypeArguments() { return new Type[] { String.class, String.class }; } }; Would this work? If not, why not? And what are some of the dangers/problems if it does (besides being able to return some Type like Integer<String> which is obviously not possible.

• Why are my JavaScript variables not persisting across functions?

  I have the following JavaScript in my HTML page referencing an HTML form on the page: <script type="text/javascript"> <!-- var myForm = document.myForm; function validateForm() { if (myForm.myInput == "") alert("Please input some text."); return false; } myForm.submit(); } function showFormInput() { myForm.reset(); document.getElementById('myInput').style.display = 'inline'; } //--> </script> ... <form name="myForm" id="myForm" action="..." method="post"> <input id="myInput" name="myInput" type="text" value="" style="display:none;" /> </form> Both functions are throwing an exception when trying to access the variable myForm, saying that "myForm is null or not an object".

• Environment Variables in C

  - by tpar44

  I know this type of question has been asked a lot but none of the answers seem to help. I set an environment variable through setenv() function call in Ubuntu Linux. However, the program doesn't seem use this environment variables. If I use getenv() it gets the correct value but the output to the program is wrong. However, when I use export BLOCKSIZE=512 in the shell, the output to the program is correct. I am not spawning different processes from the program. Below is only a code snippet of what I am doing, it is not my whole program. Is there any reason for this?
