• SForceAPI : unable to find classes listed on API? (Account, Contact, etc)

  - by Firefox

  Hi, API referred : http://www.salesforce.com/us/developer/docs/api/index.htm subsection: reference-standard objects Client side details : partner.wsdl, Axis2 1.5, generated stubs using unpacked option (-u). I was hoping to find some basic objects like Account, Contact, etc (which were listed on above url) so that I can do something like - SObject[] sObjArray = queryResult.getRecords(); for(SObject sObj : sObjArray){ Account acc = [Account] sObj; } [used above approach successfully in another webservice - 'Zuora'] However, I could not find Account class in the generated classes. I guess I am into wrong approach, but atleast I should be finding the classes listed in the reference API. Please help.

• Groovy GDK equivalent of Apache Commons StringUtils.capitalize(str) or Perl's ucfirst(str)

  - by knorv

  Yes/no-question: Is there a Groovy GDK function to capitalize the first character of a string? I'm looking for a Groovy equivalent of Perl's ucfirst(..) or Apache Commons StringUtils.capitalize(str) (the latter capitalizes the first letter of all words in the input string). I'm currently coding this by hand using .. str = str[0].toUpperCase() + str[1 .. str.size() - 1] .. which works, but I assume there is a more Groovy way to do it. I'd imagine ucfirst(..) being a more common operation than say center(..) which is a standard method in the Groovy GDK (see http://groovy.codehaus.org/groovy-jdk/java/lang/String.html).

• How to select the nth row in a SQL database table?

  - by Charles Roper

  I'm interested in learning some (ideally) database agnostic ways of selecting the nth row from a database table. It would also be interesting to see how this can be achieved using the native functionality of the following databases: SQL Server MySQL PostgreSQL SQLite Oracle I am currently doing something like the following in SQL Server 2005, but I'd be interested in seeing other's more agnostic approaches: WITH Ordered AS ( SELECT ROW_NUMBER() OVER (ORDER BY OrderID) AS RowNumber, OrderID, OrderDate FROM Orders) SELECT * FROM Ordered WHERE RowNumber = 1000000 Credit for the above SQL: Firoz Ansari's Weblog Update: See Troels Arvin's answer regarding the SQL standard. Troels, have you got any links we can cite?

• Three State Treeview Windows Forms

  - by alhambraeidos

  Hello everybody people, One of the frustrations with the standard TreeView is that you can't show a partial selection to indicate that some of the children are selected. A partial selection in a complex tree allows the user to easily determine where the selections are, even if the tree is not completely expanded. A similar idea is used in manu backup programs to allow the user to select the files to be backed up. Does anyone know of a way to make the checks in a treeview checkbox gray? I want to gray the check of a parent node when some (but not all) of its child nodes are checked. Kinda like what you see when you are selecting options to install during a software installation. I have seen several post, but is older (2000, 2007 year). I now, in 2010, the better answer possible is required. I use VS 2008 . Net 3.5 , Windows Forms Thanks in advanced, greetings

• Microsoft _stprintf warning

  - by mnh

  Why I get the following warning for the following code :) Code: _stprintf(m_szFileNamePath,_T("%s"),strFileName); warning C4996: '_swprintf': swprintf has been changed to conform with the ISO C standard, adding an extra character count parameter. To use traditional Microsoft swprintf, set _CRT_NON_CONFORMING_SWPRINTFS. I know _strprintf is a macro which if _UNICODE is defined will evaluate to _swprintf else it will be sprintf. Now what is this _swprintf. There is a function swprintf, but why is _stprintf evaluating to _swprintf instead of swprintf. What is the difference b/w the _xxx and xxx functions? EDIT: Okay there are two definitions for the UNICODE version of _stprintf, which one is included? The one in tchar.h or strsafe.h?

• TFS 2012 fresh install on fresh Windows Server 2008 warning that reporting services are not installed

  - by jshin47

  I am attempting to evaluate TFS 2012 for our organization but cannot seem to get past the first step of configuring the server using the "Standard Single Server" configuration wizard. In particular, in the service account selection screen, I am warned that: Reporting services are not installed on this computer. You need to install Reporting Services to complete TFS installation with this wizard. This is disheartening because the way I understand it, this should have been installed with the default TFS installation (in fact, no installation options are even provided) and this is a fresh and up-to-date Windows Server 2008 VM. I know I could install SQL Server 2008 or 2012 from MSDN, but shouldn't this work "out of the box?" I'd really rather use the default, small, integrated version of SQL Server that comes with TFS 2012 rather than rolling my own. If it matters, this server is joined to a domain and I am running TFS installation wizard as a domain administrator.

• How to visually represent file size

  - by Keith Williams

  This will be a bit subjective, I'm afraid, but I'd value the advice of the Collective. Our web application lists documents that users can download; standard file navigator stuff: Type Name Created Size ----------------------------------- PDF Doc 1 01/04/2010 15 KB PDF Doc 2 01/04/2010 15 MB Currently we list the file size as text, but I'd like to improve this by having some way of showing visually whether the file is tiny, normal or huge. The reason for this is so that users can scan the list quickly and spot files that are likely to take a long time downloading. My options currently are: Bigger font sizes for bigger files (drawback: the layout can become untidy) Icons (like a wi-fi signal strength indicator; drawback: harder to scan) Keep all sizes in KB so the number of zeroes indicates size (drawback: users have to calculate the "friendly" size in their heads) I know this is quite a minor thing, but I'd appreciate anyone's thoughts on the matter!

• Endianness manipulation - is there a C library for this?

  - by Malvineous

  Hi all, With the sort of programs I write (working with raw file data) I often need functions to convert between big and little endian. Usually I write these myself (which is covered by many other posts here) but I'm not that keen on doing this for a number of reasons - the main one being lack of testing. I don't really want to spend ages testing my code in a big endian emulator, and often just omit the code for big endian machines altogether. I also would rather make use of faster functions provided by various compilers, while still keeping my programs cross-platform. The only things I can find are socket calls like htons() but they require different #include files on each platform, and some GPL code like this, however that particular file, while comprehensive, seems to miss out on some of the high performance functions provided by some compilers. So, does anyone know of a library (ideally just a .h file) that is well tested and provides a standard set of functions for dealing with endianness across many compilers and platforms?

• How to enable a two-finger drag on a mac in Silverlight?

  - by Edward Tanguay

  In a Silverlight 4 application I have a ScrollViewer which I enable the user to scroll with the mouse wheel by using SetIsMouseWheelScrollingEnabled(): <ScrollViewer x:Name="CodeBoxScrollViewerModelSingular" tk:DockPanel.Dock="Left" Style="{StaticResource ScrollViewerCodeBoxStyle}"> <TextBox Text="{Binding SingularModelFileContent}" Style="{StaticResource TextBoxCodeBoxStyle}"/> </ScrollViewer> CodeBoxScrollViewerModelSingular.SetIsMouseWheelScrollingEnabled(true); However, someone tested it on a Mac and said: The only problem I noticed on a quick test was that I couldn't scroll down by using a two-finger drag, which has been standard UI behavior on the Mac for several years now. Is there any way to enable a "two-finger drag" on the Mac as you can enable mouse wheel scrolling?

• Trouble using SFML with GCC and OS X

  - by user1322654

  I've been trying to get SFML working for a while now and I've been trying to get it working using GCC. I'm on OS X by the way. I followed the standard Linux instructions and using the Linux 64-bit download however when it comes to compiling... g++ -o testing main.cpp -lsfml-system This happens: main.cpp: In function ‘int main()’: main.cpp:7: error: ‘class sf::Clock’ has no member named ‘GetElapsedTime’ main.cpp:9: error: ‘class sf::Clock’ has no member named ‘GetElapsedTime’ main.cpp:10: error: ‘Sleep’ is not a member of ‘sf’ So I thought it could be due to not using includes, so I changed my gcc compile command to: g++ -o testing main.cpp -I ~/SFML-1.6/include/ -lsfml-system and now I'm getting this error: ld: warning: ignoring file /usr/local/lib/libsfml-system.so, file was built for unsupported file format which is not the architecture being linked (x86_64) Undefined symbols for architecture x86_64: "sf::Clock::Clock()", referenced from: _main in ccZEiB7b.o "sf::Clock::GetElapsedTime() const", referenced from: _main in ccZEiB7b.o "sf::Sleep(float)", referenced from: _main in ccZEiB7b.o ld: symbol(s) not found for architecture x86_64 collect2: ld returned 1 exit status** And I have no idea what to do to fix it.

• Should I use DTOs as my data models in MVVM?

  - by JonC

  I'm currently working on what will be my first real foray into using MVVM and have been reading various articles on how best to implement it. My current thoughts are to use my data models effectively as data transfer objects, make them serializable and have them exist on both the client and server sides. It seems like a logical step given that both object types are really just collections of property getters and setters and another layer in between seems like complete overkill. Obviously there would be issues with INotifyPropertyChanged not working correctly on the server side as there is no ViewModel to which to communicate, but as long as we are careful about constructing our proper domain model objects from data models in the service layer and not dealing the the data models on the server side I don't think it should be a big issue. I haven't found too much info about this approach in my reading, so I would like to know if this is a pretty standard thing, is this just assumed to be the de facto way of doing MVVM in a multi-tier environment? If I've got completely the wrong idea about things then thoughts on other approaches would be appreciated too.

• Finding the Formula for a Curve

  - by Mystagogue

  Is there a program that will take "response curve" values from me, and provide a formula that approximates the response curve? It would be cool if such a program would take a numeric "percent correct" (perhaps with a standard deviation) so that it returns simplified formulas when laxity is permissable, and more precise (viz. complex) formulas when the curve needs to be approximated closely. My interest is to play with the response curve values and "laxity" factor, until such a tool spits out a curve-fit formula simple enough that I know it will be high performance during machine computations.

• How do I do multipled level routes best in MVC

  - by Lilja

  I have a site where I would like an URL like: /Some maincategory name/{id}/Some subcategory name/{id}/Some item name/{id} I include the IDs of each level since the name is not unique. This is doable but I have to create a new routing for each level. My Html.ActionLink also looks nasty. Each level has it's own controller since the levels are completely different. The URLs could be something like this: _/Birds/2/Waders/4/Flamingos/23_ _/Mammals/5/Dogs/23/Longeared/25/Somedog/76_ _/Insects/7/Spiders_ This is just an example and not what I'm going to use. My applications has nothing to do with animals. Is there a good way of doing this or should I use the standard routing instead?

• COM port - how to identify a device (.net/c#)

  - by argh

  Hi, I'm programming for Windows CE and I need to connect to a scanner. There is no problem - I know that it is on port COM0, but if I plug in another device earlier it gets another COM port... to get all com ports the easy way is: SerialPort.GetPortNames() But I don't know how to identify a device? Is there any standard way? I can't 'ping' it since there is one device that only sends data... it spams data all the time... and I don't know how to 'ping' a device...

• A Python IDE with Debugging and iPython Integration?

  - by skibum1981

  Does anyone know of a python IDE that has iPython as the interpreter? Using the standard interpreter just drives me nuts, as I've just grown to love using iPython and all the features it provides. To be honest, I'd rather code with a simple text editor + ipython than an IDE, but I love being able to set breakpoints with a click of a mouse, etc., so I'd like to combine both. Sorry if there's something out there and this is common knowledge. Any information/tips you can provide is GREATLY appreciated. Thanks!

• How can I write a power function myself?

  - by Koning WWWWWWWWWWWWWWWWWWWWWWW

  Since I was 12, I was always wondering how I can make a function which calculates the power (e.g. 23) myself. In most languages these are included in the standard library, mostly as pow(double x, double y), but how can I write it myself? I was thinking about for loops, but it think my brain got in a loop (when I wanted to do a power with a non-integer exponent, like 54.5 or negatives 2-21) and I went crazy ;) So, how can I write a function which calculates the power of a real number? Thanks

• PreferenceActivity used as main activity has strange animation

  - by Tobia Loschiavo

  Hi, I have a preference screen (subclass of PreferenceActivity) set as main activity (opened when the application starts). Anyway the animation android uses to open this activity is different from standard activity. It seems that two types of animation run concurrently: the usual fade animation and the right to left one. This is the code of the onCreate() method: getPreferenceManager().setSharedPreferencesName("app"); addPreferencesFromResource(R.xml.preferences); screen = getPreferenceScreen(); How can fix this glitch? Thanks

• java tool for debugging

  - by user269723

  Hi experts, Currently we are studying the java based tool which is primararily Reporting tool.It was developed in 2000/2001 period and uses many open source libraries like Apache Avalon/Mx4J.Adaptor/edu.Oswego(java concurrent package) etc. Tool uses jdk 1.3.1 and goal is to upgrade to jdk 1.5.We have also been asked to remove these 'outdated' packages and replace by standard java packages if possible. Unfortunately we have the code available for study but lacks any documentation and really difficult to track the flow(Total number of classes written might be more than 1000) during debugging. Whats the best way to understand this kind of tool? any Graphical tool to see the relationship between the classes? Thanks SR

• How to force asp.net GridView control to wrap first row within <thead> </thead> tags

  - by burak ozdogan

  Hi, I want to use Christian Bach's tableSorter client-side table sorting jQuery plugin with my asp.Net GridView control. But the problem is, in the documentation it writes: tablesorter works on standard HTML tables. You must include THEAD and TBODY tags: And unfortunately asp.net renders my GridView only with tags and header row stays within as the 1st row. I have tried: dgvRate.HeaderRow.TableSection = TableRowSection.TableHeader; after calling .DataBind(); It only helped to have <TH></TH> within the header . But still everything is inside <tbody> Can I accomplish this, I mean moving my 1st row from <tbody></tbody> to <thead></thead> ? I do not want to add it manually on PreRender stage; I am sure this could be handled much simpler, isn't it? thanks

• Compatibility of x-www-browser

  - by rohit.arondekar

  I want to open html files from a shell script. I know that Ubuntu has a command x-www-browser that will open the default browser on the system. I also found via some Googling that the command is part of the debian system. I was wondering if the command is available on non debian based distros. If it isn't is there a standard way of opening an html file in the default browser on a linux OS via command line? Note that I'm using Bash.

• Spring-Security http-basic auth in addition to other authentication types

  - by Keith

  I have a pretty standard existing webapp using spring security that requires a database-backed form login for user-specific paths (such as /user/**), and some completely open and public paths (such as /index.html). However, as this webapp is still under development, I'd like to add a http-basic popup across all paths (/**) to add some privacy. Therefore, I'm trying to add a http-basic popup that asks for a universal user/pass combo (ex admin/foo) that would be required to view any path, but then still keep intact all of the other underlying authentication mechanisms. I can't really do anything with the <http> tag, since that will confuse the "keep out the nosy crawlers" authentication with the "user login" authentication, and I'm not seeing any way to associate different paths with different authentication mechanisms. Is there some way to do this with spring security? Alternatively, is there some kind of a dead simple filter that I can apply independently of spring-security's authentication mechanisms?

• sampling integers uniformly efficiently in python using numpy/scipy

  - by user248237

  I have a problem where depending on the result of a random coin flip, I have to sample a random starting position from a string. If the sampling of this random position is uniform over the string, I thought of two approaches to do it: one using multinomial from numpy.random, the other using the simple randint function of Python standard lib. I tested this as follows: from numpy import * from numpy.random import multinomial from random import randint import time def use_multinomial(length, num_points): probs = ones(length)/float(length) for n in range(num_points): result = multinomial(1, probs) def use_rand(length, num_points): for n in range(num_points): rand(1, length) def main(): length = 1700 num_points = 50000 t1 = time.time() use_multinomial(length, num_points) t2 = time.time() print "Multinomial took: %s seconds" %(t2 - t1) t1 = time.time() use_rand(length, num_points) t2 = time.time() print "Rand took: %s seconds" %(t2 - t1) if __name__ == '__main__': main() The output is: Multinomial took: 6.58072400093 seconds Rand took: 2.35189199448 seconds it seems like randint is faster, but it still seems very slow to me. Is there a vectorized way to get this to be much faster, using numpy or scipy? thanks.

• Solutions for redundant server and client code?

  - by Fragsworth

  In our system, the code which exists on the client side (in Flash and Javascript) mirrors the code that exists on the server side (e.g. in Python or PHP), normally with respect to the models, the methods available for those models, and the unit tests written for them. This becomes a problem in systems where you want to minimize data transfer (e.g. multiplayer games). I do not want to write the same code and unit tests redundantly for both the client and server, but I don't know of any standard solutions to deal with this. Basically, I want a language/compiler which can produce models and methods for three main languages: Actionscript, Javascript, and any server language. Does something like this exist?

• Shipping GNU/Linux Firefox plugin with shared libraries (for installation with no root access)

  - by Vi

  The application is a Firefox plugin (loaded from $HOME/.mozilla/plugins), so wrapper script that sets LD_LIBRARY_PATH is not an easy option. RPATH, as far as I know, cannot refer to $HOME and can be only absolue path. Firefox tries to dlopen it's plugin from ~/.mozilla/plugins but fails (because it depends on shared libraries installed somewhere in the user home directory). Modifying Firefox menu item to provide a wrapper (with LD_LIBRARY_PATH) around Firefox is too hacky. What should installer script do (without root access) to make standard firefox load plug-ins that depends on out shared library? Should I just try to make embed everything into that .so to remove dependencies? Should I try to make installer script to finish linking or patch RPATH during the installation phase?
