• Question about how AppFabric's cache feature can be used.

  - by Kevin Buchan

  Question about how AppFabric's cache feature can be used. I apologize for asking a question that I should be able to answer from the documentation, but I have read and read and searched and cannot answer this question, which leads me to believe that I have a fundamentally flawed understanding of what AppFabric's caching capabilities are intended for. I work for a geographically disperse company. We have a particular application that was originally written as a client/server application. It’s so massive and business critical that we want to baby step converting it to a better architected solution. One of the ideas we had was to convert the app to read its data using WCF calls to a co-located web server that would cache communication with the database in the United States. The nature of the application is such that everyone will tend to be viewing the same 2000 records or so with only occasional updates and those updates will be made by a limited set of users. I was hoping that AppFabric’s cache mechanism would allow me to set up one global cache and when a user in Asia, for example, requested data that was not in the cache or was stale that the web server would read from the database in the USA, provide the data to the user, then update the cache which would propagate that data to the other web servers so that they would know not to go back to the database themselves. Can AppFabric work this way or should I just have the servers retrieve their own data from the database?

• Obj-C Sending Messages Between Classes

  - by user544359

  I'm a newbie in iPhone Programming. I'm trying to send a message from one view controller to another. The idea is that viewControllerA takes information from the user and sends it to viewControllerB. viewControllerB is then supposed to display the information in a label. viewControllerA.h #import <UIKit/UIKit.h> @interface viewControllerA : UIViewController { int num; } -(IBAction)do; @end viewControllerA.m #import "viewControllerA.h" #import "viewControllerB.h" @implementation viewControllerA - (IBAction)do { //initializing int for example num = 2; viewControllerB *viewB = [[viewControllerB alloc] init]; [viewB display:num]; [viewB release]; //viewA is presented as a ModalViewController, so it dismisses itself to return to the //original view, i know it is not efficient [self dismissModalViewControllerAnimated:YES]; } - (void)dealloc { [super dealloc]; } @end viewControllerB.h #import <UIKit/UIKit.h> @interface viewControllerB : UIViewController { IBOutlet UILabel *label; } - (IBAction)openA; - (void)display:(NSInteger)myNum; @end viewControllerB.m #import "viewControllerB.h" #import "viewControllerA.h" @implementation viewControllerB - (IBAction)openA { //presents viewControllerA when a button is pressed viewControllerA *viewA = [[viewControllerA alloc] init]; [self presentModalViewController:viewA animated:YES]; } - (void)display:(NSInteger)myNum { NSLog(@"YES"); [label setText:[NSString stringWithFormat:@"%d", myNum]]; } @end YES is logged successfully, but the label's text does not change. I have made sure that all of my connections in Interface Builder are correct, in fact there are other (IBAction) methods in my program that change the text of this very label, and all of those other methods work perfectly... Any ideas, guys? You don't need to give me a full solution, any bits of information will help. Thanks.

• How to handle javascript & css files across a site?

  - by Industrial

  Hi everybody, I have had some thoughts recently on how to handle shared javascript and css files across a web application. In a current web application that I am working on, I got quite a large number of different javascripts and css files that are placed in an folder on the server. Some of the files are reused, while others are not. In a production site, it's quite stupid to have a high number of HTTP requests and many kilobytes of unnecessary javascript and redundant css being loaded. The solution to that is of course to create one big bundled file per page that only contains the necessary information, which then is minimized and sent compressed (GZIP) to the client. There's no worries to create a bundle of javascript files and minimize them manually if you were going to do it once, but since the app is continuously maintained and things do change and develop, it quite soon becomes a headache to do this manually while pushing out new updates that features changes to javascripts and/or css files to production. What's a good approach to handle this? How do you handle this in your application?

• Opening up process and grabbing window title. Where did I go wrong?

  - by user1632018

  In my application I allow for the users to add a program from a open file dialog, and it then adds the item to a listview and saves the items location into the tag. So what I am trying to do is when the program in the listview is selected and the button is pressed, it starts a timer and this timer checks to see if the process is running, and if it isn't launches the process, and once the process is launched it gets the window title of the process and sends it to a textbox on another form. EDIT: The question is if anyone can see why it is not working, by this I mean starting the process, then when it's started closing the form and adding the process window title to a textbox on another form. I have tried to get it working but I can't. I know that the process name it is getting is right I think my problem is to do with my for loop. Basically it isn't doing anything visible right now. I feel like I am very close with my code and im hoping it just needs a couple minor tweaks. Any help would be appreciated. Sorry if my coding practices aren't that great, im pretty new to this. EDIT:I thought I found a solution but it only works now if the process has been started already. It won't start it up. Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick Dim s As String = ListView1.SelectedItems(0).Tag Dim myFile As String = Path.GetFileName(s) Dim mu As String = myFile.Replace(".exe", "").Trim() Dim f As Process Dim p As Process() = Process.GetProcessesByName(mu) For Each f In p If p.Length > 0 Then For i As Integer = 0 To p.Length - 1 ProcessID = (p(i).Id) AutoMain.Name.Text = f.MainWindowTitle Timer1.Enabled = False Me.Close() Next Else ProcessID = 0 End If If ProcessID = 0 Then Process.Start(myFile) End If Next End Sub

• Is it possible in SQLAlchemy to filter by a database function or stored procedure?

  - by Rico Suave

  We're using SQLalchemy in a project with a legacy database. The database has functions/stored procedures. In the past we used raw SQL and we could use these functions as filters in our queries. I would like to do the same for SQLAlchemy queries if possible. I have read about the @hybrid_property, but some of these functions need one or more parameters, for example; I have a User model that has a JOIN to a bunch of historical records. These historical records for this user, have a date and a debit and credit field, so we can look up the balance of a user at a specific point in time, by doing a SUM(credit) - SUM(debit) up until the given date. We have a database function for that called dbo.Balance(user_id, date_time). I can use this to check the balance of a user at a given point in time. I would like to use this as a criterium in a query, to select only users that have a negative balance at a specific date/time. selection = users.filter(coalesce(Users.status, 0) == 1, coalesce(Users.no_reminders, 0) == 0, dbo.pplBalance(Users.user_id, datetime.datetime.now()) < -0.01).all() This is of course a non-working example, just for you to get the gist of what I'd like to do. The solution looks to be to use hybrd properties, but as I mentioned above, these only work without parameters (as they are properties, not methods). Any suggestions on how to implement something like this (if it's even possible) are welcome. Thanks,

• Qt: How to use QTimer to print a message to a QTextBrowser every 10 seconds?

  - by Aaron McKellar

  Hello, I have working at this for hours and cannot figure it out nor can I find any help online that works. Basically the gist of what I am trying to accomplish is to have a Qt GUI with a button and a QTextBrowser. When I push the button I want it to diplay a message and then keep printing this message every 10 seconds. I figured I would use QTimer because it makes sense to have a timer to diplay the message every 10 seconds. When I originally implemented this into my buttonClicked() SLOT it caused the program to freeze. I looked online for a solution and found QApplication::processEvents(). So basically in my function I had something like this: while(1) { QTimer *timer; connect(...) //omitted parameters for this example timer.start(10000); ui->diplay->append("Message"); while(timer.isActive()) { QApplication::processEvents() } } I figured it would break out of the timer.isActive() while loop but it won't it simply stays in there. So I figured this is a threading issue. So I figured out how to use QThreads but I still can't get it to work. Basically when I create a thread with a timer on it and the thread tells the timer to start, the program closes and the console says "The program has unexpectedly finished". There has to be an easy way to do this but my track record with Qt has always been that th

• Algorithm to determine if array contains n...n+m?

  - by Kyle Cronin

  I saw this question on Reddit, and there were no positive solutions presented, and I thought it would be a perfect question to ask here. This was in a thread about interview questions: Write a method that takes an int array of size m, and returns (True/False) if the array consists of the numbers n...n+m-1, all numbers in that range and only numbers in that range. The array is not guaranteed to be sorted. (For instance, {2,3,4} would return true. {1,3,1} would return false, {1,2,4} would return false. The problem I had with this one is that my interviewer kept asking me to optimize (faster O(n), less memory, etc), to the point where he claimed you could do it in one pass of the array using a constant amount of memory. Never figured that one out. Along with your solutions please indicate if they assume that the array contains unique items. Also indicate if your solution assumes the sequence starts at 1. (I've modified the question slightly to allow cases where it goes 2, 3, 4...) edit: I am now of the opinion that there does not exist a linear in time and constant in space algorithm that handles duplicates. Can anyone verify this? The duplicate problem boils down to testing to see if the array contains duplicates in O(n) time, O(1) space. If this can be done you can simply test first and if there are no duplicates run the algorithms posted. So can you test for dupes in O(n) time O(1) space?

• How do you use a view with arguments as the site front page in Drupal?

  - by Justin

  I have a Drupal site and I have setup a view to power the front page. My goal is to be able to pass 0-2 arguments to the home page, that get passed into the view. However, I still need the normal Drupal pages to work. The list of arguments is known. For example: mysite.com/berlin/birds would pass in "berlin" as the first argument and "birds" as the second argument to the view that powers the front page. mysite.com/berlin would just pass in one argument, "berlin" mysite.com/admin would load the normal admin pages in Drupal I'm not clear on how to achieve this. Is there a hook I can use? I can't find one or think of one. Is there a way to specify this in the argument for the view itself? Perhaps I can write a hook that interjects when the URL is being loaded, and rewrite in the background? The solution I currently have is to add these paths (since my arguments are known) to the menu system. This works, except that when I the pages they aren't the front page, so the pages don't use the node themes I want (they use the node details theme).

• Common methods/implementation across multiple WCF Services

  - by Rob

  I'm looking at implementing some WCF Services as part of an API for 3rd parties to access data within a product I work on. There are currently a set of services exposed as "classic" .net Web Services and I need to emulate the behaviour of these, at least in part. The existing services all have an AcquireAuthenticationToken method that takes a set of parameters (username, password, etc) and return a session token (represented as a GUID), which is then passed in on calls to any other method (There's also a ReleaseAuthenticationToken method, no guesses needed as to what that does!). What I want to do is implement multiple WCF services, such as: ProductData UserData and have both of these services share a common implementation of Acquire/Release. From the base project that is created by VS2k8, it would appear I will start with, per service: public class ServiceName : IServiceName { } public interface IServiceName { } Therefore my questions would be: Will WCF tolerate me adding a base class to this, public class ServiceName : ServiceBase, IServiceName, or does the fact that there's an interface involved mean that won't work? If "No it won't work" to Question 1, could I change IServiceName so it extends another interface, IServiceBase, thus forcing the presence of Acquire/Release methods, but then having to supply the implementation in each service. Are 1 and 2 both really bad ideas and there's actually a much better solution that, knowing next to nothing about WCF, I just haven't thought of?

• Configuration Error , Finding assembly after I swapped referenced dll out. Visual Studio 2003

  - by TampaRich

  Here is the situation. I had a clean build of my asp.net web application working. I then went into the bin folder under the web app and replaced two referenced dll's with two older version of the same dll's. (Same name etc.) After testing I replaced those dll's back to the new ones and now my application keeps throwing the configuration error === Pre-bind state information === LOG: DisplayName = xxxxx.xxxx.Personalization (Partial) LOG: Appbase = file:///c:/inetpub/wwwroot/appname LOG: Initial PrivatePath = bin Calling assembly : (Unknown). LOG: Policy not being applied to reference at this time (private, custom, partial, or location-based assembly bind). I found this issue on the web and tried all the solutions to it but nothing worked. I then went into all my projects that it references under the solution and cleared out the bin/debug folder in each, I cleared out the obj folder under each and also deleted the temporary files associated with the application. I rebuilt it and it still will not work due to this error Not sure what is causing this or how to fix this issue. I have tried restarting IIS, stopping index services which was said to be a known issue. This is .net framework 1.1 app and visual studio 2003 Any suggestions would be great. Thanks.

• C# Linq Select Problem in Method Chain.

  - by Gnought

  Note that the _src inherit IQueryable<U> and V inherit new(); I wrote the following statement, there is no syntax error. IQueryable<V> a = from s in _src where (s.Right - 1 == s.Left) select new V(); But if i re-wrote it as follows, the Visual Studio editor complains an error in the "Select" IQueryable<V> d = _src.Where(s => s.Right - 1 == s.Left).Select(s=> new V()); The Error is: The type arguments cannot be inferred from the usage. Try specifying the type arguments explicitly. Candidates are: System.Collections.Generic.IEnumerable<V> Select<U,V>(this System.Collections.Generic.IEnumerable<U>, System.Func<U,V>) (in class Enumerable) System.Linq.IQueryable<V> Select<U,V>(this System.Linq.IQueryable<U>, System.Linq.Expressions.Expression<System.Func<U,V>>) (in class Queryable) Could anyone explain this phenomenon, and what the solution is to fix the error?

• Should I still be using jquery .getJson in 1.4.2?

  - by chobo2

  Hi I was looking at the 14 days of jquery http://jquery14.com/day-01/jquery-14 and I saw this and it got me to wondering is there a point to use getJson anymore? JSON and script types auto-detected by content-type (jQuery.ajax Documentation, Commit 1, Commit 2) If the response to an Ajax request is returned with a JSON mime type (application/json), the dataType defaults to “json” (if no dataType is specified). Additionally, if the response to an Ajax request is returned with a JavaScript mime type (text/javascript or application/x-javascript) , the dataType defaults to “script” (if no dataType is specified), causing the script to automatically execute. First I can see such a huge benefit of this. In jquery 1.3 I came to a situation where in some cases I would return a partial view and some cases I would return a json result (asp.net mvc). It worked in firefox but in no other browser and one of the problems was I basically had to tell jquery to either do json or text/html. With it automatically detecting I could get away with this. Anyways I found a solution around this at that time. So now it just makes me wonder if there is any point to using GetJson. I am also unsure how to set these JavaScript mime types? I am assuming that if you return a JsonResult from asp.net mvc it will set it. but I am not sure if I was just sending a text result if it would be set( I am not sure if ContentResult would set this).

• Allowing Xform controls for optional XML elements

  - by Cam

  Hi, In designing an XForm interface to an XML database (using eXist and XSLTForms), I'd like to include an input control for an optional element. The XML data records already exist and while some contain the optional element, others don't. To update a record, I'm using the existing XML record as the model instance. The problem is that the form control is not displayed when the optional element is not present, which is logical, but presents a problem when a user wants to add data to the optional element. To be more explicit, here's an example data record, data.xml: <a> <b>content</b> </a> with RNC schema: start = element a { element b { text }, element notes { text }? } XForms model: <xf:model> <xf:instance xmlns="" src="data.xml"/> <xf:submission id="save" method="post" action="update.xq" /> </xf:model> And control: <xf:input ref="/a/notes"> <xf:label>Notes (optional): </xf:label> </xf:input> The problem is that the 'Notes' input control is simply not displayed. An obvious solution is to add a trigger button to allow the user to insert the element if needed, but it is preferable to just have the input control appear, and be empty. My question is: is there some subtle combination of lesser-know attributes/binds/multiple instances/xpath expressions that will cause the control to always be displayed? Thanks

• posting form with file upload

  I am having trouble with uploading a file when using jquery. I have the following HTML in a form. <fieldset> <ul> <li> <div class="field"><input size="35" type="file" name="formFile" id="formFile"/></div> </li> <li> <div class="field"><input size="35" type="text" name="formFileName" id="formFileName" /></div> </li> </ul> </fieldset> To post the data I am using $('#myForm').ajaxForm( When I post the data and the recieved data contains some javascript, the javascript is not recognised. I expected the javscriptcode to run when the data is recieved, but it happens to early. The results indicates that $ or jquery could not be found. If I remove the name attribute from the input type=file element, there are no errors, but that is not the correct solution. How could this happen?

• LNK1104: cannot open file 'kernel32.lib'

  - by Geoff

  I Had VS2010 installed but found that intellisense wasn't working. I looked on the web and found that I wasn't the only one who had that issue. So, I installed VS2008 and everything was fine. Then I decided to clean up my computer and removed VS2010 and immediately started getting this error on my programs (new and old). Even a simple test program that has one cout command. I tried repairing VS2008 and that didn't work so I tried to uninstall and then reinstall and still I am getting the same problem. I have looked online for this issue and though I have found a lot of other people are experiencing this issue it is not the same. They are having problems with other external references, not the ones that should automatically be included like kernel32 and lib32 etc. I also tried the solution that worked for some people with their other references and I included the path (with and without quotes) to my kernel32 directory but still I get the same problem, or in some instances I will get LNK1104: cannot open file 'C:\WINDOWS\system32.obj' with and without quotes in the linker config. Can anyone please help?

• Magento, 1 db field not saved

  Hi there, I have a problem with 1 field of the db. With this code: $expireMonth = Mage::getStoreConfig('points_options/config_points/expiration_period', Mage::app()->getStore()->getId()); if (!is_null($expireMonth) && ($expireMonth > 0)) { $expireDate = date("Y-m-d H:i:s", strtotime("+" . $expireMonth .

If I uncoment the die($expireData), I see the correct value, something like 2012-01-13 13:21:12. The filed is defined as: `expire_date` datetime NULL Any thaughts? edit: the solution is: $expireDate = date("Y-m-d H:i:s", strtotime("+" . $expireMonth .

• How would you update 100+ variables if something is changed in a different class?

  - by N. Lucas

  I have a class Grid which produces a graph paper like grid on in the drawing area. I then have 5 other classes for different shapes to draw with; Line, Polygon, Ellipse, Curve, Arc Now, these 5 classes use an instance of Grid because Grid has a resolution and a scale. Inside Grid I have: public function set resolution(x:Number):void { _gap = (modBy10(x) / 10); _scale = (modBy10(x) / (this.resolution * _scale)); draw(); } public function get resolution():Number { return (_gap * 10); } public function set scale(x:Number):void { _scale = (this.resolution / x); } public function get scale():Number { return _scale; } /**/ public function scaleLength(x:Number):Number { return (x * this.scale); } public function scaleLengthDown(x:Number):Number { return (x / this.scale); } public function scaleArea(x:Number):Number { return (x / Math.pow(this.scale, 2)); } I'm just lost for a solution on how to update every instance of my 5 drawing classes when Grid is changed. For instance, Polygon is made up of multiple instances of Line, Line(length, angle) where "length" is in either in, ft, cm, or m. If the user wishes to change the scale from say 10ft per 100px resolution.. Is there an easier way than re-drawing every Line inside Polygon?

• Is it good practise to blank out inherited functionality that will not be used?

  - by Timo Kosig

  I'm wondering if I should change the software architecture of one of my projects. I'm developing software for a project where two sides (in fact a host and a device) use shared code. That helps because shared data, e.g. enums can be stored in one central place. I'm working with what we call a "channel" to transfer data between device and host. Each channel has to be implemented on device and host side. We have different kinds of channels, ordinary ones and special channels which transfer measurement data. My current solution has the shared code in an abstract base class. From there on code is split between the two sides. As it has turned out there are a few cases when we would have shared code but we can't share it, we have to implement it on each side. The principle of DRY (don't repeat yourself) says that you shouldn't have code twice. My thought was now to concatenate the functionality of e.g. the abstract measurement channel on the device side and the host side in an abstract class with shared code. That means though that once we create an actual class for either the device or the host side for that channel we have to hide the functionality that is used by the other side. Is this an acceptable thing to do: public abstract class MeasurementChannelAbstract { protected void MethodUsedByDeviceSide() { } protected void MethodUsedByHostSide() { } } public class DeviceMeasurementChannel : MeasurementChannelAbstract { public new void MethodUsedByDeviceSide() { base.MethodUsedByDeviceSide(); } } Now, DeviceMeasurementChannel is only using the functionality for the device side from MeasurementChannelAbstract. By declaring all methods/members of MeasurementChannelAbstract protected you have to use the new keyword to enable that functionality to be accessed from the outside. Is that acceptable or are there any pitfalls, caveats, etc. that could arise later when using the code?

• Django: Storing ordered, arbitrary references

  - by Sarah

  I'm new to Django, and I'm not sure what I want is possible: I have a number of items that I want each AppUser (extended User model) to be able to reference. That is, given an AppUser, I want to be able to extract its list of items in the way that AppUser has chosen to order them. In general, these items would actually be references to something else in the database, and this led me to one possible solution: Store the keys for the given objects in a CommaSeparatedIntegerField in AppUser. This way, a user could have stored {7, 3, 232, 42, 1} in their items field and both the references and their preferred order would be stored. However, this feels hacky. Since most db backends store CommaSeparatedIntegerField as a VARCHAR internally, the user is not only limited by a number of objects, but also the number of digits in their chosen items. Eg. "you may store 10 items if you choose items with itemID < 10, but only 5 items if 10 < itemID < 100". Is there a better way to do this?

• Mobile site not rendering mobile within iframe

  - by user2788371

  I'm launching a mobile version of an existing corporate web application that currently loads in an iframe for corporate authentication purposes. When accessing the web app's direct link from a mobile device, it displays beautifully. The problem is that when accessing through the iframe, the site doesn't seem to scale correctly and it looks more like I'm accessing the desktop version of the site. Any suggestions on how make the site within the iframe recognize the mobile device's width and adjust appropriately? I've tried setting the viewport within the HTML and CSS of the site being loaded and even then I'm not getting the change I expect on my iPhone. I haven't had the opportunity to test an Android yet but within our company, iOS is the most important. Some of snippets of code I have tried are listed below. I've also tried 480px and device-width (which I believe I can't access because the iframe is a different domain). Unfortunately, modifying the iframe page and settings are not an option. Also, Javascript cannot be used as a solution for other reasons. Within HTML of web app site: <meta name="viewport" content="width=320px, initial-scale=1.0, user-scalable=no" /> Within CSS of web app site: @viewport { width: 320px; } The above CSS does not seem to render even when not used in device specific @media code.

• IE8, XHTML, position: fixed; and z-index.

  - by Joel

  I have an XHTML 1.0 transitional Doctype. I have a <div> that is position: fixed; bottom: 0px; left: 0px; width: 100%; z-index: 200;. Inside that <div> I have two buttons which are position relative, aligned right, with a set z-index of 201; In Firefox the bar at the bottom and the two buttons are correctly located at the bottom. In IE8 however, the bar is visible and the z-index appears to be overlaying the other content, but the buttons are hidden behind the main div, despite being children and having their z-index set. I'm using the following meta tag; <meta http-equiv="X-UA-Compatible" content="IE=edge" /> to force the document into IE8 mode. If I emulate IE7 (put on compatability mode), the bar and buttons work just fine. I don't understand how IE7's rendering is better than IE8. I don't want to have to force compatability mode due to other things that IE7 cannot render and IE8 can. Is there another solution, or have I missed something? Thanks.

• Complexity of subset product

  - by threenplusone

  I have a set of numbers produced using the following formula with integers 0 < x < a. f(x) = f(x-1)^2 % a For example starting at 2 with a = 649. {2, 4, 16, 256, 636, 169, 5, 25, 649, 576, 137, ...} I am after a subset of these numbers that when multiplied together equals 1 mod N. I believe this problem by itself to be NP-complete (based on similaries to Subset-Sum problem). However starting with any integer (x) gives the same solution pattern. Eg. a = 649 {2, 4, 16, 256, 636, 169, 5, 25, 649, 576, 137, ...} = 16 * 5 * 576 = 1 % 649 {3, 9, 81, 71, 498, 86, 257, 500, 135, 53, 213, ...} = 81 * 257 * 53 = 1 % 649 {4, 16, 256, 636, 169, 5, 25, 649, 576, 137, 597, ...} = 256 * 25 * 137 = 1 % 649 I am wondering if this additional fact makes this problem solvable faster? Or if anyone has run into this problem previously or has any advice?

• How can I prevent the scaling of a UIWebview's content after reorientation?

  - by frankhermes

  I'm building an iOS 5/6 app that has a UIWebView. It loads some HTML that I have embedded in my app. Now when I rotate my device, the WebView changes its size (as I want it to fill the entire width of the screen). And then it gets weird: some content gets scaled up and some content doesn't get scaled up. See this image with some example text in it: As you can see, the header (H6) stays the same, while the paragraph gets scaled up. Does anybody have an idea how to prevent this? I want the html to look the same in landscape as it does in portrait mode. I've tried setting the viewport scaling to 1: <meta name="viewport" content="initial-scale=1.0,max-scale=1.0"> but that doesn't help. The body's font-size style is set to 14px, but changing that to 14pt or a percentage also made no difference. Setting the width of the body to 100% also didn't help. Strangely, removing the line break (<br/>) that's in the text fixes it but I need line breaks to be in there so that's no solution. The only thing that does work is reloading the UIWebView's content after an orientation change, but that doesn't prevent it from looking wrong during rotation, and it resets any scrolling that the user may have done. Any ideas?

• Implementing comparision operators via 'tuple' and 'tie', a good idea?

  - by Xeo

  (Note: tuple and tie can be taken from Boost or C++11.) When writing small structs with only two elements, I sometimes tend to choose a std::pair, as all important stuff is already done for that datatype, like operator< for strict-weak-ordering. The downsides though are the pretty much useless variable names. Even if I myself created that typedef, I won't remember 2 days later what first and what second exactly was, especially if they are both of the same type. This gets even worse for more than two members, as nesting pairs pretty much sucks. The other option for that is a tuple, either from Boost or C++11, but that doesn't really look any nicer and clearer. So I go back to writing the structs myself, including any needed comparision operators. Since especially the operator< can be quite cumbersome, I thought of circumventing this whole mess by just relying on the operations defined for tuple: Example of operator<, e.g. for strict-weak-ordering: bool operator<(MyStruct const& lhs, MyStruct const& rhs){ return std::tie(lhs.one_member, lhs.another, lhs.yet_more) < std::tie(rhs.one_member, rhs.another, rhs.yet_more); } (tie makes a tuple of T& references from the passed arguments.) Edit: The suggestion from @DeadMG to privately inherit from tuple isn't a bad one, but it got quite some drawbacks: If the operators are free-standing (possibly friends), I need to inherit publicly With casting, my functions / operators (operator= specifically) can be easily bypassed With the tie solution, I can leave out certain members if they don't matter for the ordering Are there any drawbacks in this implementation that I need to consider?

• Can anyone provide a good "idiot's guide" to creating an installer in VS2008 (C#) Pro?

  - by paxdiablo

  I have Visual C# 2008 Professional and have developed the first half of a C# application (console mode) with the second half in progress now (GUI). I'm looking for an easy path to creating an installer for it. What are the steps that need to be taken to produce a professional installer? There's a similar question here regarding the Express edition but I have Pro, and I would like as much as possible to stick with just the standard VS stuff (if you think you can convince me that a third party installer creator is much better than a VS-only solution, give it a shot, by all means). Keep in mind that I have no interest in upgrading to VS2010 yet, even if it's a hundred times easier to create an installer. That can come later, when the revenue starts rolling in :-) Also be aware that the GUI component of this application is a totally separate executable from the console part. The console part is a simple "open file 1, do some work on it, write file 2" type and the GUI is a fairly standard "open file, do some stuff" beast so there's no tricky or wildly undocumented behaviour happening. Basically, I'm looking for (at least) the following: professional looking installer. ability to specify where the application files go. changes to the registry to allow double-clicks on my file extension to open the GUI app with the file as an argument. needs to install everything required (my stuff, .Net if required, and so on).
