• WiX: Define made in included file not avaible from wxs-file.

  - by leiflundgren

  I have a defines.wxi-file which contains some good definitions used in all my wxs-files. When I attempt to reference the defined value I get Undefined preprocessor variable '$(var.MAGE_FOLDER)' back in my face. I guess there is something trivial I am missing here... Any ideas? defines.wxi <Include> <?define IMAGE_FOLDER="Images" ?> </Include> Product.wxs <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"> <?Include defines.wxi ?> <Product ... > <Component Id='c.Images' Directory='$(var.IMAGE_FOLDER)' />

• How to define cell width for 2 HTML tables with different column counts?

  - by DaveDev

  If I have 2 tables: <table id="Table1"> <tr> <td></td><td></td><td></td> </tr> </table> <table id="Table2"> <tr> <td></td><td></td><td></td><td></td> </tr> </table> The first has 3 columns, the second has 4 columns. How can I define a style to represent both tables when I want Table1's cell width to be 1/3 the width of the full table, and Table2's cells are 1/4 the width of the table?

• How can I define pre/post-increment behavior in Perl objects?

  - by Zaid

  Date::Simple objects display this behavior. In the case of Date::Simple objects, $date++ returns the next day's date. Date::Simple objects are immutable. After assigning $date1 to $date2, no change to $date1 can affect $date2. This means, for example, that there is nothing like a set_year operation, and $date++ assigns a new object to $date. How can one custom define the pre/post-incremental behavior of an object, such that ++$object or $object-- performs a particular action? I've skimmed over perlboot, perltoot, perltooc and perlbot, but I don't see any examples showing how this can be done.

• Is there a way to formerly define a time interval for configuring a process?

  - by gshauger

  Horrible worded question...I know. I'm working on an application that processes data for the previous day. The problem is that I know the customer is going to eventually ask to it for every hour or some other arbitrary time interval. I know that languages such as Java or SQL have masks for defining dates. Well what about a way to define a time interval? Let me ask it this way. If someone asked you to create a configurable piece of software how would you allow the user to specify the time intervals?

• Is it possible to define a virtual directory in IIS and make the files relative to the physical dire

  - by Mikey John

  Is it possible to define a virtual directory in IIS and somehow make the files in that directory relative to the physical directory and not to the virtual directory ? For instance on my server I have the following folders: D:\WebSite\Css\myTheme.css, D:\WebSite\Images\image1.jpg I created a virtual directory on IIS resources.mysite: Inside my website I reference the sheet like this resources.mysite/myTheme.css But inside myTheme.css I reference pictures from ../Images/images1.jpg. So the problem is that image1.jpg is not found because it is relative to the physical folder and not the virtual folder on IIS. Can I solve this problem without modifying the style sheet ?

• When defining a class as internal, do you define what would usually be public fields as internal?

  - by devoured elysium

  When defining a class as internal, do you define what would usually be public fields as internal? Or do you leave them as public? I have a set of classes with public/private methods that I have decided to set as internal. Now, should I change the class' modifier to internal and let the rest of the methods/properties as they are (public/private) or switch them to (internal/private)? I don't see a big point in changing it to internal, and if by some reason later I want to set them back to public it's going to give a lot of work to have to put them back to public again. Any other thoughts on this?

• Where is the appropriate place to define inflector rules in CakePHP 1.3?

  - by Daniel Wright

  In CakePHP 1.2, custom inflector rules could be defined in a file app/config/inflections.php. This file was removed in CakePHP 1.3. Instead, the documentation prescribes using the Inflector::rules function to load custom inflections. There's adequate documentation of how to define the custom inflections themselves, but the documentation gives no context—where to use Inflector::rules. Should any custom inflections be defined in the bootstrap.php script? At the top of applicable corresponding controllers? Somewhere else? See also: Configuration: Inflections in the documentation Inflector::rules definition in the API documentation

• typedef boost::shared_ptr<MyJob> Ptr; or #define Ptr boost::shared_ptr

  - by danio

  I've just started wrking on a new codebase where each class contains a shared_ptr typedef (similar to this) like: typedef boost::shared_ptr<MyClass> Ptr; Is the only purpose to save typing boost::shared_ptr? If that is the case why not do #define Ptr boost::shared_ptr in one common header? Then you can do: Ptr<MyClass> myClass(new MyClass); which is no more typing than MyClass::Ptr myClass(new MyClass); and saves the Ptr definition in each class.

• How do I define an implicit typecast from my class to a scalar?

  - by Delan Azabani

  I have the following code, which uses a Unicode string class from a library that I'm writing: #include <cstdio> #include "ucpp" main() { ustring a = "test"; ustring b = "ing"; ustring c = "- -"; ustring d; d = "cafe\xcc\x81"; printf("%s\n", (a + b + c[1] + d).encode()); } The encode method of the ustring class instances converts the internal Unicode into a UTF-8 char *. However, because I don't have access to the char class definition, I am unsure on how I can define an implicit typecast (so that I don't have to manually call encode when using with printf, etc).

• How to define supported BlackBerry OS versions and models for application?

  - by Lyubomyr Dutko

  After company wins a project it is usual to mention in contract what devices are supported and what OS versions are supported. But taking into account BlackBerry it appears sometimes to be tricky, as you can have the same device model, but two and(or) more different OS versions (or within same OS different package versions). And in this situation application may need to be updated. So the main question here is what is expected to be mentioned in contract? Could you please share some your experience of resolving such problems? So as a good example can be case of video playback issue on Storm: some issue exists on 5.0.0.XXX (network provider A) and doesn't exist on 5.0.0.YYY (network provider B), or could be following: 5.0.0.XXX1 (network provider A) - issue exist 5.0.0.XXX2 (network provider A) - issue doesn't exist The point here is to define some boundaries of development company responsibility

• How to define a static array without a contant size in a constructor of a class? (C++)

  - by Keand64

  I have a class defined as: class Obj { public: int width, height; Obj(int w, int h); } and I need it to contain a static array like so: int presc[width][height]; however, I cannot define within the class, so it it possible to create a pointer to a 2D array (and, out of curiosity, 3, 4, and 5D arrays), have that as a member of the class, and intitalize it in the constructor like: int ar[5][6]; Obj o(5, 6, &ar); If that isn't possible, is there any way to get a static array without a contant size in a class, or am I going to have to use a dynamic array? (Something I don't want to do because I don't plan on ever changing the size of the array after it's created.)

• Using static strings to define input field names in JSPs - good idea or not?

  - by Derek Clarkson

  Hi all, I've just be asked to work on a large portal project and have been looking through the established code. I keep finding this in the jsps: <input class="portlet-form-button" name="<%=ModifyUserProfile.FORM_FIRST_TIME_LOGIN_SUBMIT%>" type="submit" ... The authors are using static strings defined in classes to define the names of input fields and buttons in jsp forms. I've never seen this done before and was wondering if this is common practice. I'm inclined to think not, but I'm asking because, apart from centralising names which I would have thought are not likely to change, I can't see the reason why. Any thoughts on this?

• How do I define the default background color for window instances in a shared ResourceDictionary?

  - by Nicholas

  I can't seem to set a default background color for all of my windows in my application. Does anyone know how to do this? Currently I'm setting a theme in my App.xaml file like this. <Application> <Application.Resources> <ResourceDictionary Source="Themes/SomeTheme.xaml" /> This basically styles my entire application. Inside of SomeTheme.xaml I am trying to set a default color for all of my windows like this. <Style TargetType="{x:Type Window}"> <Setter Property="Background" Value="{DynamicResource MainColor}" /> </Style> This syntax works on a type of Button, but is completely ignored for Window. What am I doing wrong? Is there something special I have to do for a Window type.

• What are the implications of using static const instead of #define?

  - by Simon Elliott

  gcc complains about this: #include <stdio.h> static const int YY = 1024; extern int main(int argc, char*argv[]) { static char x[YY]; } $ gcc -c test1.c test1.c: In function main': test1.c:5: error: storage size of x' isn't constant test1.c:5: error: size of variable `x' is too large Remove the “static” from the definition of x and all is well. I'm not exactly clear what's going on here: surely YY is constant? I had always assumed that the "static const" approach was preferable to "#define". Is there any way of using "static const" in this situation?

• Does TCP actually define 'TCP server' and 'TCP clients'? [closed]

  - by mjn

  In the Wikipedia article, TCP communication is explained using the terms 'client' and 'server'. It also uses the word 'peers'. But TCP actually does not define "TCP clients" and "TCP servers" - In the RFC 675 document (SPECIFICATION OF INTERNET TRANSMISSION CONTROL PROGRAM), the word "client" never appears. The RFC explains that TCP is used to connect processes over ports (sockets), and that 'A pair of sockets form a CONNECTION which can be used to carry data in either direction [i.e. full duplex]. Calling the originating party the "client" seems to be common practice. But this client/server communication model is not always applicable to TCP communication. For example take peer-to-peer networks. Calling all processes which open a socket (and wait for incoming connections from peers) "TCP servers", sounds wrong to me. I would not call my uncle's telephone device a "Telephony server" if I dial his phone number and he picks up.

• In WPF XAML how can I concatenate 2 constants so I can use pre-define paths?

  - by toaster24

  I'm new to XAML, so presume I'm missing something simple. I want to replace the path part of the source path with a c# constant for easier path management, for example I have: <Image Source="/Images/Themes/Buttons/MyPicture.png" /> and in another class I have my constant defined: public static readonly string UriImagesButtons = "/Images/Big/PNG/"; I want to have something along the lines of: <Image Source="{static:UriImagesButtons + MyPicture.png}" /> This means that I can change the path globally at a stroke if the need arises. What's the syntax to do this?

• How can I call a Perl package I define in the same file?

  I need to define some modules and use them all in the same file. No, I can't change the requirement. I would like to do something like the following: { package FooObj; sub new { ... } sub add_data { ... } } { package BarObj; use FooObj; sub new { ... # BarObj "has a" FooObj my $self = ( myFoo => FooObj->new() ); ... } sub some_method { ... } } my $bar = BarObj->new(); However, this results in the message: Can't locate FooObj.pm in @INC ... BEGIN failed... How do I get this to work?

• Why people define class, trait, object inside another object in Scala?

  - by Zwcat

  Ok, I'll explain why I ask this question. I begin to read Lift 2.2 source code these days. In Lift, I found that, define inner class and inner trait are very heavily used. object Menu has 2 inner traits and 4 inner classes. object Loc has 18 inner classes, 5 inner traits, 7 inner objects. There're tons of codes write like this. I wanna to know why the author write it like this. Is it because it's the author's personal taste or a powerful use of language feature?
