• 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.

• Can I set a PHP class property from an existing variable?

  - by jasondavis

  I am trying to figure out how I want to handle settings in my PHP app. I have pretty much decide that I would like to use a Confg class file so it will be autoloaded and flexible in the future. Below is some stuff I was playing with. I know you cannot set a variable to popluate a Constant so I then try to use a public static property. Why can I not set public static $ip = $_SERVER['REMOTE_ADDR']; ?? <?php // config.class.php class Config { const URL = 'http://www.foo.com'; const DB_User = 'dbname'; public static $test = 'test string'; public static $ip = $_SERVER['REMOTE_ADDR']; } /////////////////////////////////////////////////////// //index.php // works echo Config::URL; // works echo Config::$test; // DOES NOT WORK echo Config::$ip; ?>

• Hierarchy of modules in guice

  - by Niko

  Hi, I'd like to run a unit test where a constant is slightly different than in the standard version. That is, in my default module, the following is bindConstant().annotatedWith(Names.named("number of players")).to(4); but in testing, I'd like to try this line instead: bindConstant().annotatedWith(Names.named("number of players")).to(2); Id like to achieve that without copying all of the rest of the module. What I really want is a "default" module that is "below" a more specialized module, such that in case of conflict, the specialized module wins (instead of throwing an exception, which is what guice does). In essence, my question is: how does anybody arrange for more than one module without lots of code duplication?

• Why does ElapsedTicks X 10 000 not equal ElapsedMilliseconds for .Net's Stopwatch?

  - by uriDium

  I am trying to performance test some code. I am using a stopwatch. When I output the number of milliseconds it always tells me 0 so I thought that I would try the number of ticks. I am seeing that the number of ticks is about 20 000 to 30 000. Looking at the MSDN at TimeSpan.TicksPerMillisecond it says that is 10 000 ticks per millisecond. In that case why are the elapsed milliseconds on my stopwatch not appearing as 2 or 3? What am I missing? I have even outputed the result on the same line. This is what I get. Time taken: 26856 ticks, 0 ms And it is constant.

• QT4, paginated showing elements

  - by matiit

  I am going to write an application that uses QT4 (with C++ or python it isnt important in that moment). One of functionality is "Showing all items in database". One item has a Title, author, description and photo (constant size) And there could be very many items. Let's say 400. There won't be enough space to show'em all at once time. One row will have 200px, so i need at most 4 for once time. How to paginate them? I have no idea. I can use limit and offset in SQL queries, but how to tell window: "that's 5th page"? Any solutions?

• Windows service - supplying arguments in "path to executable"

  - by Jono

  I cannot figure out how to pass (constant) arguments into my Windows service when it is started. I'm using the standard .NET classes like ServiceBase to implement (and ServiceProcessInstaller and ServiceInstaller to install) my service. On the general tab of a Windows Service properties dialog box (once installed), there's a "Path to executable" in which I can see that some of the standard Windows services have command line arguments specified. System.ServiceProcess.ServiceBase.OnStart takes string[] args, which I presume would enable these arguments to be accessed from within .NET code. Are there some properties on ServiceProcessInstaller or ServiceInstaller that I can set to allow me to pass startup arguments to my own service, or does anyone know how it's supposed to be done?

• Giving Users an Option Between UDP & TCP?

  - by cam

  After studying TCP/UDP difference all week, I just can't decide which to use. I have to send a large amount of constant sensor data, while at the same time sending important data that can't be lost. This made a perfect split for me to use both, then I read a paper (http://www.isoc.org/INET97/proceedings/F3/F3_1.HTM) that says using both causes packet/performance loss in the other. Is there any issue presented if I allow the user to choose which protocol to use (if I program both server side) instead of choosing myself? Are there any disadvantages to this? The only other solution I came up with is to use UDP, and if there seems to be too great of loss of packets, switch to TCP (client-side).

• Nested loop with dependent bounds trip count

  - by aaa

  hello. just out of curiosity I tried to do the following, which turned out to be not so obvious to me; Suppose I have nested loops with runtime bounds, for example: t = 0 // trip count for l in 0:N for k in 0:N for j in max(l,k):N for i in k:j+1 t += 1 t is loop trip count is there a general algorithm/way (better than N^4 obviously) to calculate loop trip count? I am working on the assumption that the iteration bounds depend only on constant or previous loop variables.

• Understanding c++ block of code

  - by kotoko

  I was given a c++ main and have to code it so it works. I am having some trouble understanding the code as I am a bit new to cpp. Here is the code int main(int argc, char *argv[]) { Class::setAtribute("string"); Class(Class::CONSTANT) << "starting up..."; } Some questions: How can the first line work with no variables? Is it static? The second line is really strange for me, what I can make out is a Constructor that takes in a class constante and then prints it out somehow? If someone could explain me this bit of code it would be great! Thanks in advance.

• How to validate inclusion of time zone?

• How to detect if breaking an edge will make a graph disjoint?

  - by the_graph_guy

  I have a graph that starts off with a single, root node. Nodes are added one by one to the graph. At node creation time, they have to be linked either to the root node, or to another node, by a single edge. Edges can also be created and deleted (one by one, between any two nodes). Nodes can be deleted one at a time. Node and edge creation, deletion operations can happen in any arbitrary order. OK, so here's my question: When an edge is deleted, is it possible do determine, in constant time (i.e. with an O(1) algorithm), if doing this will divide the graph into two disjoint subgraphs? If it will, then which side of the edge will the root node belong? I'm willing to maintain, within reasonable limits, any additional data structure that can facilitate the derivation of this information. Maybe it is not possible to do it in O(1), if so any pointers to literature will be appreciated.

• C# (ASP.Net) Linking selection values to constants in Codebehind

  - by jasonvogel

  ASPX Code <asp:RadioButtonList ID="rbServer" runat="server" > <asp:ListItem Value=<%=ServerDeveloper%>> Developer </asp:ListItemv <asp:ListItem Value="dev.ahsvendor.com"> dev.test.com</asp:ListItem> <asp:ListItem Value="staging.ahsvendor.com"> staging.test.com</asp:ListItem> </asp:RadioButtonList> ASPX.CS - Codebehind const string ServerDeveloper = "developer"; ASPX Error: Code blocks are not supported in this context. Question: So what is the correct way to tie an dropdown/radio buttion/... ASPX value to a constant that is shared with the CodeBehind code? I know that I could do rbServer.Add.Item("developer") [from the CodeBehind], but is there a way to achieve it from the Presentation side of things?

• What does :this means in Ruby on Rails?

  - by Marco

  Hi, I'm new to the Ruby and Ruby on Rails world. I've read some guides, but i've some trouble with the following syntax. I think that the usage of :condition syntax is used in Ruby to define a class attribute with some kind of accessor, like: class Sample attr_accessor :condition end that implicitly declares the getter and setter for the "condition" property. While i was looking at some Rails sample code, i found the following examples that i don't fully understand. For example: @post = Post.find(params[:id]) Why it's accessing the id attribute with this syntax, instead of: @post = Post.find(params[id]) Or, for example: @posts = Post.find(:all) Is :all a constant here? If not, what does this code really means? If yes, why the following is not used: @posts = Post.find(ALL) Thanks

• Which is the better way to avoid magic string keys? Using string const keys in a class or using enumeration?

  - by user596314

  My idea is to avoid magic string keys in my Asp.Net MVC application. To do so, I want to create string constant keys to be shared in the application. For example, I can write TempData[MyClass.Message] or TempData[MyEnum.Message.ToString()] instead of TempData["Message"]. public class MyClass { public const string Message = "Message"; } and public enum MyEnum { Message, Others } My questions are: Which is the better way to avoid magic string keys? Using string const keys in a class or using enumeration together with ToString()?

• iPhone Accelerometer Values

  - by Mike

  My question is about the iPhone accelerometer. Does the accelerometer measure acceleration or movement of the iPhone? What I mean is if I hold the iPhone and go from 0mph to 60mph, I would expect the measure of acceleration to increase in value from 0 to 60, but once I reach 60, I expect the value to return to 0 since I am "no longer accelerating" but am moving at a constant speed. Now if the accelerometer measure motion, I would expect it to register 0 to 60 and continue to provide a change in value as I move forward at 60mph. Sorry, I looked at a few books, programmed some code (values seemed to small to give a recognizable result over short distances or speeds), and a lot of web searches, and I am trying to get an answer to this question. Thanx!

• I would like to pipe output of find into input list of scp, how?

  - by user13184

  I'm a novice linux user and I am trying to send a long list of files from one computer to another. The argument list is too long, so I am using find. I am having trouble setting up the expression, though. Can someone help? Here is what I would normally type for a short argument list. scp ./* phogan@computer/directory... Here's I think this might translate into with find. scp find . -name "*" phogan@computer/directory... Maybe I could use piping? Any suggestions would help. Thanks in advance.

• drop-down combo box-like functionality for queries.

  - by Frank Developer

  Is it possible to provide the following type of fuctionality with informix client tools? As the user types the first two characters of a name, the drop-down list is empty. At the third character, the list fills with just the names beginning with those three characters. At the fourth character, MS-Access completes the first matching name (assuming the combo's AutoExpand is on). Once enough characters are typed to identify the customer, the user tabs to the next field. The time taken to load the combo between keystrokes is minimal. This occurs once only for each entry, unless the user backspaces through the first three characters again. If your list still contains too many records, you can reduce them by another order of magnitude by changing the value of constant conSuburbMin from 3 to 4.

• How do you manage web navigation info in your application?

  - by Dave

  I’m building an application where different users will have different menu items available to them depending on what they’ve paid for. There will also be multiple levels to the menu hierarchy. What’s the best approach to this problem? I’m assuming I need a database table that represents the menu hierarchy, including the parent-child relationships of the nodes in the navigation as well as the sorting of the items. Then another table which I use to manage whether a user is authorized to access a particular item in that table. When I render the view, I’d reference the menus, and the access rights of the user to output the menu, and I’d also need a function to check that same authorization from each controller in case a user manually types in a URL of a controller they’re not supposed to have access to. Is this the right approach? Any suggestions for caching this to prevent the constant look-ups of this type of info? I’m open to any suggestions on how you may have approached this type of requirement.

• GDI+, using DrawImage to draw a transperancy mask of the source image

  - by sold

  Is it possible to draw a transperancy mask of an image (that is, paint all visible pixels with a constant color) using Graphics::DrawImage? I am not looking for manually scanning the image pixel-by-pixel and creating a seperate mask image, I wonder if it's possible to draw one directly from the original image. My guessing is that it should be done with certain manipulations to ImageAttributes, if possible at all. The color of the mask is arbitrary and should be accurate, and it would be a plus if there can be a threshold value for the transparency.

• Reconstructing simple 3d enviroment(room) from photo

  - by Riz

  I have photo of a room with three walls and floor/ceiling or both. I am trying to reconstruct this room in 3d asking user for minimal input. Right now I use 8 points defined by user, angles of left and right wall(they can be quite different from 90) and one size "InLeftBottom-InRightBottom"(I need to have real size of this room for later use). I have no info about user's camera(I can read EXIF to get FOV and use constant height but this can be only used as additional info). Is this possible to ask user for less info? Maybe it's possible to get wall angles without user interaction? Or maybe I am completly wrong and should use different approach?

• C++ get method - returning by value or by reference

  - by HardCoder1986

  Hello! I've go a very simple question, but unfortunately I can't figure the answer myself. Suppose I've got some data structure that holds settings and acts like a settings map. I have a GetValue(const std::string& name) method, that returns the corresponding value. Now I'm trying to figure out - what kind of return-value approach would be better. The obvious one means making my method act like std::string GetValue(const std::string& name) and return a copy of the object and rely on RVO in performance meanings. The other one would mean making two methods std::string& GetValue(...) const std::string& GetValue(...) const which generally means duplicating code or using some evil constant casts to use one of these routines twice. #Q What would be your choice in this kind of situation and why?

• How do I set ORDER BY params using prepared PDO statement?

  - by Marlorn

  I'm having problems using params in the ORDER BY section of my SQL. It doesn't issue any warnings, but prints out nothing. $order = 'columnName'; $direction = 'ASC'; $stmt = $db->prepare("SELECT field from table WHERE column = :my_param ORDER BY :order :direction"); $stmt->bindParam(':my_param', $is_live, PDO::PARAM_STR); $stmt->bindParam(':order', $order, PDO::PARAM_STR); $stmt->bindParam(':direction', $direction, PDO::PARAM_STR); $stmt->execute(); The :my_param works, but not :order or :direction. Is it not being internally escaped correctly? Am I stuck inserting it directly in the SQL? Like so: $order = 'columnName'; $direction = 'ASC'; $stmt = $db->prepare("SELECT * from table WHERE is_live = :is_live ORDER BY $order $direction"); Is there a PDO::PARAM_COLUMN_NAME constant or some equivalent? Thanks!
