• Basic SQL query question

  - by user318573

  Hello, I have the following query: SELECT Base.ReportDate, Base.PropertyCode, Base.FirstName, Base.MiddleName, Base.LastName, Person.FirstName, Person.MiddleName, Person.LastName FROM LeaseT INNER JOIN Base ON LeaseT.LeaseID = Base.LeaseID INNER JOIN Person ON LeaseT.TenantID = Person.ID works fine, except there could be 0 to 'N' people in the 'Person' table for each record in the Base table, but I only want to return exactly 1 for each 'Base' record (doesn't matter which, but the one with the lowest Person.ID) would be a reasonable choice. If there is 0 rows in the person table, I still need to return the row, but with null values for the 'person' fields. How would I structure the SQL to do that? Thanks. Edit: Yes, the tables are probably not structured properly, but restructuring at this time is not possible - got to work with what is there.

• problem-configure-jboss-to-work-with-jndi(3)

  - by Spiderman

  Sorry for opening new thread every time for the same problem. It's just that I'd like to refine my question during my investigation and it's hard to do it in stackoverflow structure on the same question (maybe on purpose). Anyway, in continuation to this thread http://stackoverflow.com/questions/2843218/problem-configure-jboss-to-work-with-jndi2 I discovered that when running an application that is deployed on my JBoss 4.2.3.GA, when I perform: Context initialContext = new InitialContext(); Object dataSource = initialContext.lookup("java:/DefaultDS"); I get null as a return value even though DefaultDS is the default datasource that comes with Jboss installation. and generally, how come initialContext return null value? if the datasource is not found it should throw NamingException and in other case it should return real object. What can I do with null? isn't it a bad error handling of javax.naming.InitialContext ???

• Development enviroment for .NET

  - by user137348

  I'm about to create an development enviroment for a little developer company(3-4 developers + some testers). Our development platform is .NET and Oracle. My question is how to structure the whole enviroment.How many servers do I need ? Should be one server for developers and one for testers ? I'd like to have one build server (TeamCity). Where to put the Subversion ? Visual Studio's would be on developers laptops. Do I need one database for development and one extra for build server ? What else could be helpful ??

• Should all presentational images be defined in CSS?

  - by Grant Crofton

  I've been learning (X)HTML & CSS recently, and one of the main principles is that HTML is for structure and CSS for presentation. With that in mind, it seems to me that a fair number of images on most sites are just for presentation and as such should be in the CSS (with a div or span to hold them in the HTML) - for example logos, header images, backgrounds. However, while the examples in my book put some images in CSS, they are still often in the HTML. (I'm just talking about 'presentational' images, not 'structural' ones which are a key part of the content, for example photos in a photo site). Should all such images be in CSS? Or are there technical or logical reasons to keep them in the HTML? Thanks, Grant

• converting tabular structures in a Word document into an actual table or reading data from the tabul

  - by Chris

  I have a macro which can read the last cell/column of all tables in a Word 2003/2007 document and store the data in an MS-Access table. But, some Word documents have the data in structures like a table format but are not actually tables. The structure looks like a table, but the table borders are actually line connectors. These documents were created by a software(VeryPDF PDF to Word converter) which converted the PDF documents(the original format these documents were) into Word documents. Is there a way I can convert/replace the tabular structures with actual tables in Word so that I can use the macro? Or, is there a way I can read the value of the last column from the tabular structures using some VBA code? Any advice would be appreciated.

• Design guidelines for cache mechanism

  - by Delashmate

  Hi All, I got assignment to write design for cache mechanism (this is work assignment, not homework), This is my first time writing a design document, Our program display images for doctors, and we want to reduce the parsing time of the images So we want to save the parsed data in advance (in files or inside database) Currently I have several design key ideas: Handle locks - each shared data structure should be handled, also files Test - add test to verify the data from the cache is equal to the data from the files To decouple the connection to the database- not to call directly to the database Cleanup mechanisem- to delete old files if the cahce directory exceed configurable threshold Support config file Support performance tool in the feature I will also add class diagram, data flow charts, and workflow What do you think I should add to the key ideas? Do you know good link to atricales about design? Thanks in advance, Dan

• Find a variable with a given value in VS2008

  - by Aaron

  I have an instance variable with several members, many of which have their own members and so on. Using the debugger and watch variables, I found a string variable with a specific value that I need by diving into this variable's members. However, after spending some time on other things and coming back to this, I am now unable to find where this value is located. When I have my application paused, is there a way to search the values of variables in the current context for a given value? To clarify, if I have the given structure: myVariable | |--aMember1 | |--subMember = "A value" | |--aMember2 |--subMember = "Another value" Is there a way (possibly using the watch list in VS debugger) to search myVariable for any member or submember with the value "A value", returning to me the path myVariable->aMember->subMember?

• Should I pass the BrainBench Design patterns certification?

  - by Fedyashev Nikita

  I have found Design patterns certification at the Brainbehch. I have heard from people who passed it, that there are many Language-specific patterns questions, mostly from Java and C++. I think that this certification can: force me to improve my skills on Object oriented design and design patterns; improve and structure my knowledge of the domain; give real estimate of my knowledge, which is useful issue itself The only confusion I have about this certification, is that I have to learn C++/Java language specific design patterns, while I mostly do PHP development and don't want to switch to C++/Java. I'm familiar with Java & C++ syntax, read lots of books about different subjects with code snippets in this programming languages. I think, that if I pass well all concepts except language specific patterns at certification, it won't be very good, because this concepts will gain quite low results. What would you recommend in this particular circumstance?

• How to add characters to reach the maximum size of a char[].

  - by Bon_chan

  Hi folks, I have the following part of code : for(int i=0;i<n;i++) { printf("Student %d\n",i+1); printf("Enter name : "); scanf("%s",&(student+i)->name); fflush(stdin); lengthName = strlen((student+i)->name); while(lengthName !='\0') { }} when the length is shorter than 10, it will add hyphens until reaching the maximum size. Ex : John = 6 hyphens will be added I know how to do it in csharp but can't figure it out in c. Could some of you give me some lights please? PS : Oh yes the variable name is char name[10+1] and it a part of the structure called student.

• problem in `delete-directory` with enabled `delete-by-removing-to-trash`

  - by Andreo

  There is a strange behavior of delete-directory function with enabled flag delete-by-removing-to-trash. It deletes files one by one instead of applying move-file-to-trash to the directory. As a result emacs deletes big directories slowly and there are many files in the trash after deleting, so it is impossible to restore the directory. Example: Directory structure: ddd/ ccc/ 1.txt There are three files in the trash after deleting ddd: trash/ ddd/ ccc/ 1.txt instead of one: trash/ ddd/ It is very slow, because emacs traverse directory recursively. I can't restore deleted directory. What i need is exactly the same behavior as of move-file-to-trash. But it should be transparent (i.e. 'D x' in dired mode). How to solve the problem? As a temporary solution i see the making advice function for `delete-directory'.

• dymanic columns in mysql tables?

  - by fayer

  i want to add dynamic columns in a mysql table. but i dont know exactly how. i want to let the user add some columns (fields) in a thread. eg. let him add a integer field and a value (eg. price: 199) or a string field and a value (eg. name: teddybear). the user can add as many field/value-pairs as he wants. i thought i could create a many-to-many table: thread <- thread_field <- field thread: id, title thread_field: field_id, thread_id, value field: id, name is this a good structure? but in this way i have to set a specific column type of thread_field.value. either its an integer or a string. i want to have the possibility to have it dymanic, let the user choose. how can i do this? thanks!

• How do you set a cookie to be accessible across the entire domain in Javascript

  - by Tzarkov

  I suppose there should be a way to set a cookie to be accessible from the entire domain nevermind from which directory you are setting the cookie. Say in mypage.com/blue/index.php y set the cookie "colour=blue;" this way: document.cookie = "colour" + "=" + "blue" + "; expires=" + expireDate.toGMTString() + "; path=/"; Using this code, the cookie retrieval function in mypage.com/home.php can't access the content of the cookie. If it was just from first level directories that the cookie needs to be set, we would be ok by doing path=../ instead of path=/ But how do you go about writing generic code that sets a cookie that is accessible from any page in that domain not minding how deep in the file structure is the page the cookie is being set from?

• Calculating statistics directly from a CSV file

  - by User1

  I have a transaction log file in CSV format that I want use to run statistics. The log has the following fields: date: Time/date stamp salesperson: The username of the person who closed the sale promo: sum total of items in the sale that were promotions. amount: grand total of the sale I'd like to get the following statistics: salesperson: The username of the salesperson being analyzed. minAmount: The smallest grand total of this salesperson's transaction. avgAmount: The mean grand total.. maxAmount: The largest grand total.. minPromo: The smallest promo amount by the salesperson. avgPromo: The mean promo amount... I'm tempted to build a database structure, import this file, write SQL, and pull out the stats. I don't need anything more from this data than these stats. Is there an easier way? I'm hoping some bash script could make this easy.

• Can I write to different jetty databases using JPA that is using the same "entity class"

  - by Per

  I am using Java persistance and there EntityManager class and have it assigned to storage a class object that shall be written to the database. My problem is that I want to write to different databases using the same storage class. My solution to that was to write a StorageManagerfactory that has a Map holding all EntityManagers. The solution looked good until I looked at the databases and realized that all information (undepending of the Map, which gets the correct value) was written to the same database (one of the initialised in the Map). So my question is: Can I write to different databases using JPA that is using the same storage class (the class holding the structure of my database)? Thanks

• How to use SQLiteOpenHelper without or less restrictive use of Context?

  - by Pentium10

  If you extend SQLiteOpenHelper, for the Constructor you have to use a Context. I am wondering if there is a way to leave this out, and be able to work with database tables without a Context. Or at least be least restrictive, I mean a way of project/class structure that will make history the several context passings I have to do now. As it is my application has several level of classes, chained in each other, and there are a few that connects to the database, but have no whatsoever influence on the interface, so they don't actually need the Context. Are you creating your classes in the way that you pass each time a Context to them? If not, how you do, how you reuse a Context in a short class?

• Storing tree data in Javascript

  - by Ozh

  I need to store data to represent this: Water + Fire = Steam Water + Earth = Mud Mud + Fire = Rock The goal is the following: I have draggable HTML divs, and when <div id="Fire"> and <div id="Mud"> overlap, I add <div id="Rock"> to the screen. Ever played Alchemy on iPhone or Android? Same stuff Right now, the way I'm doing this is a JS object : var stuff = { 'Steam' : { needs: [ 'Water', 'Fire'] }, 'Mud' : { needs: [ 'Water', 'Earth'] }, 'Rock' : { needs: [ 'Mud', 'Fire'] }, // etc... }; and every time a div overlaps with another one, I traverse the object keys and check the 'needs' array. I can deal with that structure but I was wondering if I could do any better? Edit: I should add that I also need to store a few other things, like a short description or an icon name. So typicall I have Steam: { needs: [ array ], desc: "short desc", icon:"steam.png"},

• Any tips of how to handle hierarchial trees in relational model?

  - by George

  Hello all. I have a tree structure that can be n-levels deep, without restriction. That means that each node can have another n nodes. What is the best way to retrieve a tree like that without issuing thousands of queries to the database? I looked at a few other models, like flat table model, Preorder Tree Traversal Algorithm, and so. Do you guys have any tips or suggestions of how to implement a efficient tree model? My objective in the real end is to have one or two queries that would spit the whole tree for me. With enough processing i can display the tree in dot net, but that would be in client machine, so, not much of a big deal. Thanks for the attention

• Right-click on a Listbox in a Silverlight 4 app.

  - by AngryHacker

  I am trying to implement what I used to take for granted in Winforms applications. I am a Silverlight noob, so hopefully all this is elementary. I have a listbox in a Silverlight 4 app. I'd like to do the following: Right-click on the listbox Have the item under the location where I click highlight itself I'd like a context menu to popup (with my own items in the context menu) From my research so far, it appears that there is no ContextMenu construct in Silverlight, instead we have to build up a Grid/Canvas structure and attach it to a Popup object, which is what is then popped up. My questions are as follows: To accomplish #2, I need some kind of hit test on the listbox. I can't figure out how to do that and my google-fu isn't helping. Once I do identify the index under the mouse, how do I actually select the item? Is there a reusable Context menu component somewhere that I can use? Extra credit if the component allows arbitrary sub-menus.

• size of structures in .NET

  - by redpaladin

  My problem is very simple. My problem is to send a structure between a program in C to a C# program. I made a struct in C#: public struct NetPoint { public float lat; // 4 bytes public float lon; // 4 bytes public int alt; // 4 bytes public long time; // 8 bytes } Total size of the struct must be 20 bytes. When I do a sizeof() of this struct: System.Diagnostics.Debug.WriteLine("SizeOf(NetPoint)=" + System.Runtime.InteropServices.Marshal.SizeOf(new NetPoint())); The debug console shows: SizeOf(NetPoint)=24 But I expected to have 20 bytes. Why do I see a difference?

• Django model class and custom property

  - by dArignac

  Howdy - today a weird problem occured to me: I have a modle class in Django and added a custom property to it that shall not be saved into the database and therefore is not represent in the models structure: class Category(models.Model): groups = models.ManyToManyField(Group) title = defaultdict() Now, when I'm within the shell or writing a test and I do the following: c1 = Category.objects.create() c1.title['de'] = 'german title' print c1.title['de'] # prints "german title" c2 = Category.objects.create() print c2.title['de'] # prints "german title" <-- WTF? It seems that 'title' is kind of global. If I change title to a simple string it works as expected, so it has to do something with the dict? I also tried setting title as a property: title = property(_title) But that did not work, too. So, how can I solve this? Thank you in advance! enter code here
