• Can I show a single country (masked out) in GoogleMaps?

  - by NIclas Lindbegr

  Hello! Is it possible to mask away neighbor countries in GoogleMap? In my case I just want to show Sweden on one view. On a second view just Norway, Denmark etc etc... I know it is possible to draw polygon lines and fill them accordingly on to Maps API. Problem is that or the result sets get huge or the lines get very rough etc... Would be nice if GoogleMaps could deliver a country at the time without neighbors. Does anyone know about a good coordinate database with country borders? Best best regards, Niclas

• OpenGL - lighting of vertices outside clip range

  - by hmp

  I have a problem with lighting in my OpenGL application. When one of the vertices of a drawn polygon goes outside the front clip plane (or has z<0, I'm not sure which), the polygon stops being lighted properly. This however happens on only one machine I tested, with Intel GMA950 card. On nVidia and ATI cards everything looks fine. I guess I am breaking some OpenGL rule here? How should I deal with it? I'd try dividing the scene into smaller polygons, but I'm not sure if it guarantees the case is eliminated (all polygons stepping outside the clipping range are offscreen).

• How to force adodb php library to use lowercase field names

  - by spam

  I'm trying to use adodb for db access in my webapp. However my hosting provider has mysql case sensitive, and I have all my fields in lowercase. But when I call getInsertSQL function, I got them in uppercase. Is there a way to force adodb to use lowercase? I tried with define('ADODB_ASSOC_CASE', 0); $ADODB_ASSOC_CASE = 0; But it seems to be ignored as the constant is suppose to be used only with oracle, MSSQL and other DBMS $conn = &ADONewConnection($this->DbType); $conn = PConnect($dbServer,$dbUser, $dbPassword,$database); $tableName = "sample"; $insertSQL = $conn->GetInsertSQL($tableName,$objDB); And I got the SQL statement with the column names in uppercase.

• Determining a Flex event's default behavior

  - by Jeremy Mitchell

  How can I tell what the default behavior for a cancelable event is? For example, I read somewhere that the TextEvent.TEXT_INPUT has a default behavior and that default behavior includes adding a text character associated with the key that was pressed to a TextInput. That makes perfect sense. But if I hadn't read that, how would I know what the default behavior is? Other than guessing. In this case, it's probably obvious. But in other situations, it might not be. For example, in the docs, look at DataGridEvent.HEADER_RELEASE's cancelable property. It says: cancelable: true so, there appears to be a "default behavior" associated with a DataGridEvent.HEADER_RELEASE event. But what is it? And why would I cancel it if I'm not really sure what it is? :) thanks.

• How can I execute a bunch of editor commands stored in a file in VIM?

  - by LES2

  I have read the other posts, e.g., http://stackoverflow.com/questions/1830886/vim-executing-a-list-of-editor-commands and others. The answer isn't clear to me for my case. I have some editor commands that I generated from an SQL query. It uses :s/foo/bar to change country codes (from FIPS to a non-standard code set). Here's a sample of the file: :s/CB/CAMBO :s/CQ/NMARI :s/KV/KOSOV :s/PP/PAPUA ... I have saved that in a file called fipsToNonStd.vim (unsure about the correct extension). I want to run those commands one after another. What's the easiest way to do so? Thanks a bunch! SO Rocks!

• Distributing a function over a single dimension of an array in MATLAB?

  - by Alex Feinman

  I often find myself wanting to collapse an n-dimensional matrix across one dimension, and can't figure out if there is a concise incantation I can use to do this. For example, when parsing an image, I often want to do something like this. (Note! Illustrative example only. I know about rgb2gray for this specific case.) img = imread('whatever.jpg'); s = size(img); for i=1:s(1) for j=1:s(2) bw_img = mean(img(i,j,:)); end end I would love to express this as something like: bw = on(color, 3, @mean); or bw(:,:,1) = mean(color); Is there a short way to do this?

• Why does concatenating strings in the argument of EXEC sometimes cause a syntax error in T-SQL?

  - by Tim Goodman

  In MS SQL Server Management Studio 2005, running this code EXEC('SELECT * FROM employees WHERE employeeID = ' + CAST(3 AS VARCHAR)) gives this error: Incorrect syntax near 'CAST' However, if I do this, it works: DECLARE @temp VARCHAR(4000) SET @temp = 'SELECT * FROM employees WHERE employeeID = ' + CAST(3 AS VARCHAR) EXEC(@temp) I found an explanation here: http://stackoverflow.com/questions/1044831/t-sql-cannot-pass-concatenated-string-as-argument-to-stored-procedure According to the accepted answer, EXEC can take a local variable or a value as its argument, but not an expression. However, if that's the case, why does this work: DECLARE @temp VARCHAR(4000) SET @temp = CAST(3 AS VARCHAR) EXEC('SELECT * FROM employees WHERE employeeID = ' + @temp) 'SELECT * FROM employees WHERE employeeID = ' + @temp sure looks like an expression to me, but the code executes with no errors.

• Tomcat 6 Realm Config with Windows AD

  - by mat

  We have Tomcat 6 connecting to a Win2k3 Server running AD. The realm is configured as such <Realm className="org.apache.catalina.realm.JNDIRealm" debug="99" referrals="follow" connectionURL="<url>" connectionName="CN=Query Account,OU=Service Accounts,DC=company,DC=com" connectionPassword="<pwd>" userBase="OU=Users,DC=company,DC=com" userSubtree="true" userSearch="(sAMAccountName={0})" userRoleName="member" roleBase="OU=Security Groups,DC=company,DC=com" roleName="cn" roleSearch="(member={0})" roleSubtree="true"/> Our groups in AD are such Security Groups (OU) IT (OU) IT Support (OU) Support Staff (CN) The LDAP security works if in the web.xml, I speficy Support Staff. i.e works for Common names. We want ANY user under Security Groups OU to have access to the application and not just the CN. Tomcat does not search OU's and it just searches CN's in our case. How do we configure our settings so we can do OU level authorization and not just CN level ? thanks Mat

• Inheritance in tables - structure problem

  - by Naor

  I have 3 types of users in my system. each type has different information I created the following tables: BaseUser(base_user_id, username, password, additional common data) base_user_id is PK and Identity UserType1(user_id, data related to type1 only) user_id is PK and FK to base_user_id UserType2(user_id, data related to type2 only) user_id is PK and FK to base_user_id UserType3(user_id, data related to type3 only) user_id is PK and FK to base_user_id Now I have relation from each type of user to warehouses table. Users from type1 and type2 should have only warehouse_id and users from type3 should have warehouse_id and customer_id. I thought about this structure: WarehouseOfUser(base_user_id,warehouse_id) base_user_id is FK to base_user_id in BaseUser WarehouseOfTyp3User(base_user_id,warehouse_id, customer_id) base_user_id is FK to base_user_id in BaseUser The problem is that such structure allows 2 things I want to prevent: 1. add to WarehouseOfTyp3User data of user from type2 or type1. 2. add to WarehouseOfUser data of user from type3. what is the best structure for such case?

• Is it possible to transfer data between html pages driven by spring web flow?

  - by Easwaramoorthy Kanagaraj

  I am aware of passing data between jsp in spring web flow. Is it possible to transfer data between html pages driven by spring web flow. I don't want to use the HTML5 local storage capabilities. Example: Page 1: Search box for an employee id. Page 2: Search result for the employee details. Two ways that I could think: Get the employee details in page 1 by ajax and pass the result to the page two. Pass the employee id to page 2 and get the result by ajax in onload. In both case I need to pass any variable/data. I am confused in doing this. Is there anything in the Spring webflow using which I could do this? Thanks in advance, Easwar

• php search and replace

  - by Dave

  I am trying to create a database field merge into a document (rtf) using php i.e if I have a document that starts Dear Sir, Customer Name: [customer_name], Date of order: [order_date] After retrieving the appropriate database record I can use a simple search and replace to insert the database field into the right place. So far so good. I would however like to have a little more control over the data before it is replaced. For example I may wish to Title Case it, or convert a delimited string into a list with carriage returns. I would therefore like to be able to add extra formatting commands to the field to be replaced. e.g. Dear Sir, Customer Name: [customer_name, TC], Date of order: [order_date, Y/M/D] There may be more than one formatting command per field. Is there a way that I can now search for these strings? The format of the strings is not set in stone, so if I have to change the format then I can. Any suggestions appreciated.

• What's the best way to add tags to the head in Plone?

  - by J. Pablo Fernández

  I want to add the link tags to redirect my web-site to my OpenID provider. These tags should go in the head element. What's the best way to add them in Plone? I understand that filling the head_slot is a way to do it, but that can only happen when you are adding a template to the page and that template is being rendered. In my case I'm not adding any template. Which template should I modify (that is not main_template.pt, which is my current solution, with it's huge drawbacks).

• Linq to NHibernate - How to include parent object and only certain child objects

  - by vakman

  Given a simplified model like the following: public class Enquiry { public virtual DateTime Created { get; set; } public virtual Sender Sender { get; set; } } public class Sender { public virtual IList<Enquiry> Enquiries { get; set; } } How can you construct a Linq to Nhibernate query such that it gives you back a list of senders and their enquiries where the enquiries meet some criteria. I have tried something like this: return session.Linq<Enquiry>() .Where(enquiry => enquiry.Created < DateTime.Now) .Select(enquiry => enquiry.Sender) In this case I get an InvalidCastException saying you can't cast type Sender to type Enquiry. Any pointers on how I can do this without using HQL?

• Split String in C# without delimiter (sort of)

  - by Zach

  Hi, I want to split a string in C#.NET that looks like this: string Letters = "hello"; and put each letter (h, e, l, l, o) into an array or ArrayList. I have no idea what to use as the delimiter in String.Split(delimiter). I can do it if the original string has commas (or anything else): string Letters = "H,e,l,l,o"; string[] AllLettersArray = Letters.Split(",".ToCharArray()); But I have no idea what to use in a case with (supposedly) no delimiter. Is there a special character like Environment.Newline? Thanks.

• Detecting DOM event support in Firefox

  - by Andy E

  What's the best way to detect event support in Firefox. Opera, Internet Explorer and Safari/Chrome all support eventName in object, but Firefox doesn't. My test case is this: javascript:alert("onclick" in document.createElement("a")) Which alerts true when entered into the address bar on the aforementioned browsers, and alerts false for Firefox. I figured out a solution using typeof on an event like so: var a = document.createElement("a"); a.setAttribute("onclick", ""); alert(typeof(a.onclick) == "function"); Is there a better method of detecting event support in Firefox?

• Compare Date objects with different levels of precision

  - by brainimus

  I have a JUnit test that fails because the milliseconds are different. In this case I don't care about the milliseconds. How can I change the precision of the assert to ignore milliseconds (or any precision I would like it set to)? Example of a failing assert that I would like to pass: Date dateOne = new Date(); dateOne.setTime(61202516585000L); Date dateTwo = new Date(); dateTwo.setTime(61202516585123L); assertEquals(dateOne, dateTwo);

• gcc options for fastest code

  - by rwallace

  I'm distributing a C++ program with a makefile for the Unix version, and I'm wondering what compiler options I should use to get the fastest possible code (it falls into the category of programs that can use all the computing power they can get and still come back for more), given that I don't know in advance what hardware, operating system or gcc version the user will have, and I want above all else to make sure it at least works correctly on every major Unix-like operating system. Thus far, I have g++ -O3 -Wno-write-strings, are there any other options I should add? On Windows, the Microsoft compiler has options for things like fast calling convention and link time code generation that are worth using, are there any equivalents on gcc? (I'm assuming it will default to 64-bit on a 64-bit platform, please correct me if that's not the case.)

• Automatic initialization routine in C++ library?

  - by Robert Mason

  If i have a header file foo.h and a source file foo.cpp, and foo.cpp contains something along the lines of: #ifdef WIN32 class asdf { asdf() { startup_code(); } ~asdf() { cleanup_code(); } }; asdf __STARTUP_HANDLE__ #else //unix does not require startup or cleanup code in this case #endif but foo.h does not define class asdf, say i have an application bar.cpp: #include "foo.h" //link in foo.lib, foo.dll, foo.so, etc int main() { //do stuff return 0; } If bar.cpp is compiled on a WIN32 platform, will the asdf() and ~asdf() be called at the appropriate times (before main() and at program exit, respectively) even though class asdf is not defined in foo.h, but is linked in through foo.cpp?

• Is it necessarily bad style to ignore the return value of a method

  - by Jono

  Let's say I have a C# method public void CheckXYZ(int xyz) { // do some operation with side effects } Elsewhere in the same class is another method public int GetCheckedXYZ(int xyz) { int abc; // functionally equivalent operation to CheckXYZ, // with additional side effect of assigning a value to abc return abc; // this value is calculated during the check above } Is it necessarily bad style to refactor this by removing the CheckXYZ method, and replacing all existing CheckXYZ() calls with GetCheckedXYZ(), ignoring the return value? The returned type isn't IDisposable in this case. Does it come down to discretion?

• Database Design for One to One relationships

  - by Greelmo

  I'm trying to finalize my design of the data model for my project, and am having difficulty figuring out which way to go with it. I have a table of users, and an undetermined number of attributes that apply to that user. The attributes are in almost every case optional, so null values are allowed. Each of these attributes are one to one for the user. Should I put them on the same table, and keep adding columns when attributes are added (making the user table quite wide), or should I put each attribute on a separate table with a foreign key to the user table. I have decided against using the EAV model. Thanks!

• Using enums or a set of classes when I know I have a finite set of different options?

  - by devoured elysium

  Let's say I have defined the following class: public abstract class Event { public DateTime Time { get; protected set; } protected Event(DateTime time) { Time = time; } } What would you prefer between this: public class AsleepEvent : Event { public AsleepEvent(DateTime time) : base(time) { } } public class AwakeEvent : Event { public AwakeEvent(DateTime time) : base(time) { } } and this: public enum StateEventType { NowAwake, NowAsleep } public class StateEvent : Event { protected StateEventType stateType; public MealEvent(DateTime time, StateEventType stateType) : base(time) { stateType = stateType; } } and why? I am generally more inclined to the first option, but I can't explain why. Is it totally the same or are any advantages in using one instead of the other? Maybe with the first method its easier to add more "states", altough in this case I am 100% sure I will only want two states: now awake, and now asleep (they signal the moments when one awakes and one falls asleep).

• lists:keyfind problems

  - by dagda1

  Hi, I cannot for the life of me get lists:keyfind to work as I expect in Erlang. I have the following eunit test: should_find_key_test() -> NewList = lists:keystore("key", 1, [], {"key", "value"}), Value = case lists:keyfind("key", 1, NewList) of false -> notfound; {_key, _value} -> _value end, ?debugVal(Value). Whenever I run this test I get the following error message: indextests:should_find_key_test (module 'indextests')...failed ::error:undef in function lists:keyfind/3 called as keyfind("key",1,[{"key","value"}]) in call from indextests:should_find_key_test/0 Can anyone see what I am doing wrong? Is it saying that lists:keyfind no longer exists? Cheers Paul
