• Getting a Method's Return Value in the VS Debugger

  - by Bullines

  Is it possible to get a method's return value in the Visual Studio debugger, even if that value isn't assigned to a local variable? For example, I'm debugging the following code: public string Foo(int valueIn) { if (valueIn > 100) return Proxy.Bar(valueIn); else return "Not enough"; } Since I'm not setting any local variables in Foo, and assuming I'm not setting a break point in whatever's calling Foo, is there a way to see what the return value is if I have a breakpoint inside of Foo (or another way)? I don't have much experience with the Autos or Intermediate windows, so I'm not sure if those are even a valid option or not.

• iPhone Options for reading item from XML?

  - by fuzzygoat

  I am accessing this data from a web server using NSURL, what I am trying to decide is should I read this as XML or should I just use NSScanner and rip out the [data] bit I need. I have looked around the web for examples of extracting fields from XML on the iPhone but it all seems a bit overkill for what I need. Can anyone make any suggestions or point me in the right direction. In an ideal world I would really like to just specify [data] and get a string back "2046 3433 5674 3422 4456 8990 1200 5284" <!DOCTYPE tubinerotationdata> <turbine version="1.0"> <status version="1.0" result="200">OK</status> <data version="1.0"> 2046 3433 5674 3422 4456 8990 1200 5284 </data> </turbine> any comments / ideas are much appreciated. gary

• Is wordpress a good platform for webapp development?

  - by darlinton

  I am planning a webapp to control bank paying orders. In a quick review, the user goes online and creates a payment order. This order goes to other people that pays it and register the payment on the system. The system keeps track of all the payments, keeping the account balance up-to-date. The system needs a login system, bank integration, and to support at some point thousands of clients. We can find articles on the web about the benefits of using wordpress platform to build webapps. However, I could not find discussion with counterarguments to user wordpress. As the platform the most important choice in webapp project, I would to know more about the pitfalls and harms for choosing wordpress. The question is: What are the benefits and harms for choosing wordpress as a development platform for a webapp that need to be integrated with other system (backend systems) and to handle thousands of users (does it scale up?)?

• Creating an iphone book application

  - by ennuikiller

  I have some experience creating iphone applications and would now like to create an iphone book application. Browsing the Book category in iTunes it seems to there is a standard format for building these apps, however, googling for how to build an iphone book app produces no useful results. This type of application is also not addressed in any of the iphone development books I've seen. Is there a standard method fot building these book applications? Or is it simply copying the text is some format (pdf, txt, html?) and then writing a document handling api? It seems there already must exist apis for doing this. Can anyone point me in the right direction. Thanks in advance!

• Installing unsigned x64 driver to work with libusbdotnet

  - by user216194

  Hi all- I am currently in a Windows 7 dev. environment working to get a device to initialize with libusbdotnet. The device (a USB mass storage device) connects and runs using the default USB-MASS Storage driver for Windows. I want to replace this driver with the one created by the .INF Wizard in libusbdotnet. The operating system is a 64-bit, and by default the INF Wizard produces this driver, but I am unable to selected it because it is "unsigned" I believed, when I go to "Pick from a list of drivers" and point to the directory where the newly created device drivers are. I have enabled "TEST MODE" using DESO but I'm still unable to select this file. Anyone familiar with libusbdotnet, or directing devices to work with a specific driver that is unsigned in Window (do I need the .inf file? or the .sys???) do you have any advice about where I'm going wrong? Thanks!

• Verify my form workflow

  - by Shackrock

  I have a form, with some sensitive info (CC numbers). My work flow is: One page to take all form items Upon submission, values are validated. If all is well, all data is stored in a session variable, and the page reloads and displays this info from the session variable. If everything is ok on the review page, the user clicks submit and the session variable is sent to another form for processing (sending payment). Upon success, the session is destroyed. Upon failure (bad CC number, for example) - the user is sent back to the form, with all of the fields filled in just like before, so that they can check for errors and try again (session is NOT destroyed). Does anyone see anything wrong with this, from a security or best practices stand point? UPDATE I'm thinking I can get rid of a step - storing the info in a session EVER. Just have a one page checkout, no review page... makes sense.

• On WindowsMobile, how can i tell what other processes are reserving shared memory space?

  - by glutz78

  On WindowMobile 6.1, I am using VirtualAlloc to reserve 2MB chunks, which will return me an address from the large shared memory area so allocations do not count against my per process virtual space. (doc here: http://msdn.microsoft.com/en-us/library/aa908768.aspx) However, on some devices i notice that I am not able to reserve memory after a certain point. VirtualAlloc will return NULL (getlasterror() says out of memory). The only explanation for this that I see is that another process has already reserved a bunch of memory and my process is therefore unable to. Any idea where I can find a tool to show me the shared mem region of a WM device? Thanks.

• Fossil gpg workflow for teams

  - by Alex_coder

  I'm learning fossil and trying to reproduce a workflow for two people modifying the same source code tree. So, Alice and Bob both have local repositories of some source code. Both have autosync off. Alice hacks some more, does some commits signing check-ins with her gpg key. This part is fine, as Alice I've managed to generate gpg keys, fossil asked me the key password when commiting. I'm also aware of gpg-agent but don't use it yet, because I'm trying to keep things as simple as possible for now. Now, at some point Bob pulls changes from Alice's fossil repo. How would he verify Alice's signed check-ins?

• Do FormViews not respond to commands issued from an ImageButton?

  - by Duke

  I am using ImageButtons in place of LinkButtons in a FormView to issue New/Edit/Delete/Cancel commands, but they don't seem to have an effect on the FormView. The ImageButtons will cause a postback but the FormView mode doesn't change from the current mode. I'm sure the ImageButtons were working at one point, but I've been busy with other pages for a while. The only thing that's changed between now and then are some patches I installed in Visual Studio. I haven't been able to find any information related to this issue other than this: http://www.codeproject.com/KB/webforms/TamingTheFormView.aspx In that article there's an onclick method for an ImageButton that's used to change the FormView mode. Would that be the only way to use ImageButtons instead of LinkButtons in a FormView?

• Split a html string in N parts

  - by Matt Brailsford

  Hi Guys, Does anybody have an example of spliting a html string (coming from a tiny mce editor) and splitting it into N parts using C#? I need to split the string evenly without splitting words. I was thinking of just splitting the html and using the HtmlAgilityPack to try and fix the broken tags. Though I'm not sure how to find the split point, as Ideally it should be based purley on the text rather than the html aswell. Anybody got any ideas on how to go about this? Many thanks Matt

• Silverlight MEF Embedded Resources

  - by Fastidious

  I have two different Silverlight UserControls imported with MEF from two different xaps. The UserControls are simply an Image on a Canvas. Both UserControls have the image marked as 'Resource'. The images are different but their names are the same (key point). I'm not quite sure what's going on behind the scenes of the MEF import but both images seem to end up in the same AppDomain. After the composition when I stick the UserControls on a Canvas, each is an instance of the class it should be, but they both show the same image. Obviously if the image file names are unique across all xaps I import I have no problem but I don't like that solution. Is there a better one?

• ZedGraph labels

  - by eKek0

  In ZedGraph how to show text labels for each point and in the XAxis all together? EDIT: If I do myPane.XAxis.Type = AxisType.Text; myPane.XAxis.Scale.TextLabels = array_of_string; I get labels on the XAxis like this And if I do for (int i = 0; i < myCurve.Points.Count; i++) { PointPair pt = myCurve.Points[i]; // Create a text label from the Y data value TextObj text = new TextObj(pt.Y.ToString("f0"), pt.X, pt.Y + 0.1, CoordType.AxisXYScale, AlignH.Left, AlignV.Center); text.ZOrder = ZOrder.A_InFront; text.FontSpec.Angle = 0; myPane.GraphObjList.Add(text); } I get labels on the curve, like this But if I do both at the same time, labels on the curve disappear. Is there a way to combine both kind of labels?

• How to stop Lean programming becoming Cowboy Coding?

  - by Matt Howells

  My team has been progressively adopting more and more lightweight methodologies, moving from Scrum to Lean/Kanban where there is less and less formal process. At some point we will be back to Cowboy Coding; indeed I fear we may already be on the border line. Where can the line be drawn between a very lightweight Lean and Agile process and anarchy? How will we know when we have crossed the line? And how can we prevent ourselves from crossing the line? The question might also be phrased as, 'what processes cannot be safely eliminated in Lean's drive to eliminate waste'?

• Batch file to wait for other program to load/initialize, then execute command?

  - by Jason N

  I need some assistance writing what should be a fairly basic .BAT file. I load my main program, but that program takes ~20secs to load and be initialized. I have another command-line API I can execute to interact with this above program, but obviously until the above program is loaded and initialized there's no point in trying. If the program isn't running the command-line API returns a string stating exactly this - otherwise it just works and exits. Easy. So I want to wait until the above is loaded/initialized before firing my API command(s) at it. I could place a sleep/wait in there, but I want something more solid. The ~20sec wait is not necessarily consistent. Any way to execute the command-line API over and over until the response is satisfactory, then exit? J

• Exception design: Custom exceptions reading data from file?

  - by User

  I have a method that reads data from a comma separated text file and constructs a list of entity objects, let's say customers. So it reads for example, Name Age Weight Then I take these data objects and pass them to a business layer that saves them to a database. Now the data in this file might be invalid, so I'm trying to figure out the best error handling design. For example, the text file might have character data in the Age field. Now my question is, should I throw an exception such as InvalidAgeException from the method reading the file data? And suppose there is length restriction on the Name field, so if the length is greater than max characters do I throw a NameTooLongException or just an InvalidNameException, or do I just accept it and wait until the business layer gets a hold of it and throw exceptions from there? (If you can point me to a good resource that would be good too)

• Java Google App Engine inconsistent data lose after restarting dev server

  - by user259349

  Hello everyone, I am using Java GAE. So far, i'm just scafolding my data objects and i'm seeing an interesting issue. The records that i am playing around with are getting updated properly as long as my dev server is running up. The second that the my dev server gets restarted, i lose all of my changes. That would be not alarming if i lost all of my records, but, there was a point of time where my data persisted through the server restart. I'm worried that i would lose production data if i launched without fixing this potential bugs? ANy idea on wher ei should look?

• How to set probability for a targetSprite shooting accuracy in shooting game ?

  - by srikanth rongali

  Hi, My code is ion cocos2D. I have written code for generating the bullets from the enemy gun for every 0.3seconds. The enemySprite is in right side of the screen in (land scape mode) at winSize.height/2. the bullet starts from the same point and reach the player's end. I used rand() to generate y-coordinate for the bullet to hit on player side. Now, if the bullet bounded rectangle meets the player bounded rectangle the enemy won. If it misses enemy shoots again after 0.3 seconds. Every thing is fine up to here for me. But I have 10 enemies and each have accuracy of hitting player of probabilities ranging from 0.80 to 1.0. First enemy probability is .80 and 10 enemy's is 1.0. How can I adjust the probability for enemy such that it runs according to its probability. Player also hits the enemy.

• Table-level diff and sync procedure for T-SQL

  - by Ville Koskinen

  I'm interested in T-SQL source code for synchronizing a table (or perhaps a subset of it) with data from another similar table. The two tables could contain any variables, for example I could have base table source table ========== ============ id val id val ---------- ------------ 0 1 0 3 1 2 1 2 2 3 3 4 or base table source table =================== ================== key val1 val2 key val1 val2 ------------------- ------------------ A 1 0 A 1 1 B 2 1 C 2 2 C 3 3 E 4 0 or any two tables containing similar columns with similar names. I'd like to be able to check that the two tables have matching columns: the source table has exactly the same columns as the base table and the datatypes match make a diff from the base table to the source table do the necessary updates, deletes and inserts to change the data in the base table to correspond the source table optionally limit the diff to a subset of the base table, preferrably with a stored procedure. Has anyone written a stored proc for this or could you point to a source?

• breakthrough programming .net era

  - by Andrew Florko

  I wonder what are .net technologies / c# language improvements you consider as breakthrough in .net era for the last 5-10 years. I mean technologies that shifted developers mind. For example direct-x made assembler nearly abandoned for game programming in the end of XX century and JQuery extremely simplified ajax web development as well as javascript code reusability. What kind of breakthrough .net technologies you expect in the future and what modern .net technologies are just a light evolution of well known approaches. Do you consider .net 4.0 parallel extensions and other improvements as breakthrough, or may be we have reached the point when nothing radical is expected in modern programming?

• Design of Business Layer

  - by Adil Mughal

  Hi, We are currently revamping our architecture and design of application. We have just completed design of Data Access Layer which is generic in the sense that it works using XML and reflection to persist data. Any ways now we are in the phase of designing business layer. We have read some books related to Enterprise Architecture and Design so we have found that there are few patterns that can be applied on business layer. Table Pattern and Domain Model are example of such patterns. Also we have found Domain Driven Design as well. Earlier we decided to build Entities against table objects. But we found that there is difference in Entities and Value Objects when it comes to DDD. For those of you who have gone through such design. Please guide me related to pattern, practice and sample. Thank you in advance! Also please feel free to discuss if you didn't get any point of mine.
