Calling a WPF Appliaction and modify exposed properties?

- by Justin

I have a WPF Keyboard Application, it is developed in such a way that an application could call it and modify its properties to adapt the Keyboard to do what it needs to. Right now I have a file *.Keys.Set which tells the appliaction (on open) to style itself according to that new style. I know this file could be passed as a command line argument into the appliaction. That would not be a problem. My concern is, is thier a way via a managed environment to change the properties of the executable as long as they are exposed properly, an example: 'Creates a new instance of the Keyboard Appliaction Dim e_key as new WpfAppliaction("C:\egt\components\keyboard.exe") 'Sets the style path e_key.SetStylePath("c:\users\joe\apps\me\default.keys.set") e_key.Refresh() 'Applies the style e_key.HideMenu() 'Hides the menu e_key.ShowDeck("PIN") 'Shows the custom "deck" of keyboard keys the developer 'Created in the style appliaction. ''work with events and resposne 'Clear the instance from memory e_key.close e_key.dispose e_key = nothing This would allow my application to become easily accessible to other Touch Screen Application Developers, allowing them to use my key_board and keep the functionality they need. It seems like it might be possible because (name of executable).application shows all the exposed functions, properties, and values. I just have never done this before. Any help would be appreciated, thank you in advance.

How to add additional condition to the JOIN generated by include?

- by KandadaBoggu

I want to add additional criteria to the LEFT OUTER JOIN generated by the :include option in ActiveRecord finder. class Post has_many :comments end class Comment belongs_to :post has_many :comment_votes end class CommentVote belongs_to :comment end Now lets say I want to find last 10 posts with their associated comments and the up comment votes. Post.find.all(:limit => 10, :order => "created_at DESC", :include => [{:comments => :comment_votes]) I cant add the condition to check for up votes as it will ignore the posts without the up votes. So the condition has to go the ON clause of the JOIN generated for the comment_votes. I am wishing for a syntax such as: Post.find.all(:limit => 10, :order => "created_at DESC", :include => [{:comments => [:comment_votes, :on => "comment_votes.vote > 0"]) Have you faced such problems before? Did you managed to solve the problem using the current finder? I hope to hear some interesting ideas from the community. PS: I can write a join SQL to get the expected result and stitch the results together. I want to make sure there is no other alternative before going down that path.

Freetype2 (error-)return value documentation

- by Awaki

In short, I'm looking for documentation that would limit the error situations to check for after a Freetype library function failed, much like the OpenGL and Win32 APIs document the error codes generated by their respective functions. I can't seem to find such documentation though, so I was wondering how to best handle translation of Freetype errors to typed exceptions. Background: I am currently in the process of implementing font-rendering capability (using Freetype) for my GUI framework, which makes strong use of typed exceptions to indicate error situations. However, the Freetype docs seem to completely omit what errors can be expected from what functions. That, if such documentation does indeed not exist, would basically leave me with two options: either guessing which errors make sense for a certain Freetype function (obviously prone to mistakes on my part), or considering every error code for translation into appropriate exceptions (less verbose since I would have to write the translation only once). Performance isn't really critical in the code that calls the Freetype library, so even the latter option would probably be acceptable, but surely there must be some kind of documentation on which library calls may return what Freetype error? Is there any such documentation which I just somehow managed to not find? Should I go the route of generically expecting every error code for translation? Or are there other ways to approach this problem? By the way, I wanted to avoid introducing some kind of generic FreetypeException (containing a description of the Freetype error) since I intended to completely hide what libraries I'm using (not from a legal point-of-view, mind you), but I guess I can be convinced to do this anyway if the consensus is that it would be the best option. I don't think it matters for this question, but I'm writing in C++.

Is there a way to capture a bitmap from a WPF window using native C++?

- by Mike Caron

Imagine a document window in a MDI application which contains a child WPF window, say a sidebar for example. How can one get a bitmap containing both the WPF pixels AND the GDI (non-wpf) pixels? I've discovered that when making my thumbnail preview for the Win7 taskbar app icon hover, I get black in the parts of the preview where the WPF pixels should be. My current method simply grabs a bitmap capture of the document window. Then I get a DC for the preview, make a memory DC from it and select my bitmap into it. Then I do some size adjustments and bitblt the memory dc to the real dc. I'm guessing that the BitBlt operation doesn't take into account the fact that the WPF pixels are hardware accelerated and therefore need to be grabbed from the graphics hardware. All the stuff in GDI is managed just fine, though and when there's no WPF child windows, the preview image looks fine. I'm wondering if it's at all possible to grab a bitmap of the WPF window from native C++. Then I can blt that onto the black area of the previous preview.

My website keeps crashing IE, can't debug

- by Ninja rhino

I have a website that suddenly started to crash internet explorer. The website loads and starts executing javascript but somewhere in there the machinery explodes. I don't even get a script error, it just crashes. I've tried to manually step through every single line of js with the built in debugger but then of course the problem doesn't occur. If i choose to debug the application when it crashes i see the following message. Unhandled exception at 0x6c5dedf5 in iexplore.exe: 0xC0000005: Access violation reading location 0x00000090. The top 5 items in the call stack looks like this VGX.dll!6c5dedf5() [Frames below may be incorrect and/or missing, no symbols loaded for VGX.dll] VGX.dll!6c594d70() VGX.dll!6c594f63() VGX.dll!6c595350() VGX.dll!6c58f5e3() mshtml.dll!6f88dd17() VGX.dll seems to be part of the vml renderer and i am in fact using VML. I'm not suprised because i've had so many problems with vml, attributes has to be set in specific order, sometimes you cant set attributes when you have elements attached to the dom or vice versa (everything undocumented btw) but then the problems can usually be reproduced when debugging but not now :( The problem also occurs in no plugin-mode. Is there a better approach than trial and error to solve this? Edit: Adding a console outputting every suspect modification to the DOM made the problem only occur sometimes. (the console is also implemented in javascript on the same page, i'm able to see the output even after a crash as the window is still visible) Apparently it seems to be some kind of race condition. I managed to track it down even further, and it seems to occur when you remove an object from the DOM too quickly after it's just been added. (most likely only for vml-elements with some special attribute, didn't try further) And it can't be fixed by adding a dead loop in front of removeChild(pretty bad solution anyway), the page has to be rendered by the browser once after the addChild before you can call removeChild. sigh

I read 3 pages of a JQuery book and here's my reaction and question

- by George

My jQuery reaction to the language's flexible "selectors" is probably rooted in this experience: I once had managed a project where a developer constructed a web page that was used by users to provide very flexible search parameters for a search screen using dynamic sql string building based on the user's specified search parameter. The resulting queries were usually very complicated and involved joins to many tables. One of the options that the user had was to choose from one of 3 an options. Depending on the user's choice for this option, the resulting SQL would need to query a different set of database columns. For example, if choice option "A" were selected, the resulting database columns queried would be prefixed with "A_"; if option "B" were selected, he resulting database columns queried would be prefixed with "B_" and so on. The developer choice to write all the complete SQL assuming that the user selected, for example, option "A" and therefore first constructed SQLs of this type: SQL = "SELECT A_COL1, A_COL2, A_COL3 FROM TABLE ..." and then after constructing one of a million possible variations on the Query From Hell, did something like this: If UserOption = "B" then SQL = SQL.Replace("A_","B_") 'replace everywhere End if He insisted that this was the easiest was to code it, and while I understood that, I was concerned about maintenance of this code. You see, this worked for a while, but as the search options grew and the database columns evolved, the various "REPLACE small substring" with another small substring had unexpected consequences when applied to an evolving database and new search options. My feeling is that code should be written as much as possible such that you can add to it without fear of breaking what is already there. I feel a better approach, though a bit more work, would have been to write a function to return the appropriate target column based on a common set name and the user selected option. OK, so what does this have to do with jQuery selectors? Are the ultra flexible JQuery selectors kind of like perform a "replace all" on a SQL string? Handy as hell but potentially creating a maintenance nightmare?

How to configure a NSPopupButton for displaying multiple values in a TableView?

- by jekmac

Hi there! I'm using two entities A and B with to-many-to-many relationship. Lets say I got an entity A with attribute aAttrib and a to-many relationship aRelat to another entity B with attribute bAttrib and a to-many relationship bRelat with entity A. Now I am building an interface with two tables one for entity A and another for entity B. The table for entity B has two columns one for bAttrib and one for the relationship aRelat. The aRelat-column should be a NSPopupButtonCell to display multiple aAttrib values. I'd like to set all the bindings in InterfaceBuilder in Table Column Bindings: -- I have two NSArrayController each for one entity: Object Controller Mode:Entity Array Controller Bindings: Parameters Managed Object Context bind to File's Owner -- One Table Cloumn with a PopUpButtonCell: TableCloumnBindings Content bind to Entity A with ControllerKey arrangedObjects; Content Values bind to Entity A with ModelKeyPath aAttrib Selected Object bind to Entity B with ModelKeyPath bRelat I know that this configuration doesn't allow multiple value setting. But I don't know how to do the right one. Getting the following message: HIToolbox: ignoring exception 'Unacceptable type of value for to-many relationship: property = "bRelat"; desired type = NSSet; given type = NSCFString; value = testValue.' that raised inside Carbon event dispatch... Does anyone have any idea?

How to make cycle over cycles in Java?

- by Roman

I would like to make a cycle over the following elements: [1,2,11,12,21,22,111,112,121,122,....,222222] or for example [1,2,3,11,12,13,21,22,23,31,32,33,111,112,113,... 333333333] How can I make it in Java? In my particular case I use 4 digits (1,2,3,4) and the length of the last number can be from 1 to 10. I managed to do it in Python and PHP. In the first case I used list over lists. I started from [[1],[2],] then for every element of the list I added 1 and 2, so I got [[1,1],[1,2],[2,1],[2,2]] and so on: nchips = sum(chips) traj = [[]] last = [[]] while len(last[0]) < nchips: newlast = [] for tr in last: for d in [1,2,3,4]: newlast.append(tr + [d]) last = newlast traj += last When I did it in PHP I used number with base 3. But it was a tricky and non elegant solution. for ($i=-1; $i<=$n; $i+=1) { if ($i>-1) { $n5 = base_convert($i,10,5); $n5_str = strval($n5); $tr = array(); $found = 0; for ($j=0; $j<strlen($n5_str); $j+=1) { $k = $n5_str[$j]; if ($k==0) { $found = 1; break; } array_push($tr,$k); } if ($found==1) continue; } else { $tr = array(); } } Can it be done easily in Java?

Creating serializeable unique compile-time identifiers for arbitrary UDT's.

- by Endiannes

I would like a generic way to create unique compile-time identifiers for any C++ user defined types. for example: unique_id<my_type>::value == 0 // true unique_id<other_type>::value == 1 // true I've managed to implement something like this using preprocessor meta programming, the problem is, serialization is not consistent. For instance if the class template unique_id is instantiated with other_type first, then any serialization in previous revisions of my program will be invalidated. I've searched for solutions to this problem, and found several ways to implement this with non-consistent serialization if the unique values are compile-time constants. If RTTI or similar methods, like boost::sp_typeinfo are used, then the unique values are obviously not compile-time constants and extra overhead is present. An ad-hoc solution to this problem would be, instantiating all of the unique_id's in a separate header in the correct order, but this causes additional maintenance and boilerplate code, which is not different than using an enum unique_id{my_type, other_type};. A good solution to this problem would be using user-defined literals, unfortunately, as far as I know, no compiler supports them at this moment. The syntax would be 'my_type'_id; 'other_type'_id; with udl's. I'm hoping somebody knows a trick that allows implementing serialize-able unique identifiers in C++ with the current standard (C++03/C++0x), I would be happy if it works with the latest stable MSVC and GNU-G++ compilers, although I expect if there is a solution, it's not portable.

How to format dates in Jahia 6 CMS?

- by dpb

I am helping a friend of mine put up a site for his business. I’ve read different posts and sites trying to find the ideal CMS tool, but people have different views of what is the best, so I finally just picked one of them at random. So I went for an evaluation of Jahia 6.0-CE. As you’ve probably guessed by now, I don’t have so much experience with CMS tools. I just want to setup the CMS, write the templates for the site and let my friend manage the content from there on. So I extracted the sources from SVN and went for a test drive. I managed to create some simple templates to get a hang of things but now I have an issue with a date format. In my definitions.cnd I declared the field like so: date myDateField (datetimepicker[format='dd.MM.yyyy']) This is formatted in the page and the selector also presents this in the dd.MM.yyyy format when inserting the content. But how about sites in other countries, countries that represent the date as MM.dd.yyyy for example? If I specify the format in the CND, hard coded, how can I change this later on so that it adapts based on the browser’s language? Do I extract the content from the repository and format it by hand in the JSP template based on a Locale, or is there a better way? Thank you.

Outlook VSTO AddIn for Meetings

- by BigDubb

We have created a VSTO addin for Outlook Meetings. As part of this we trap on the SendEvent of the message on the FormRegionShowing event: _apptEvents.Send += new Microsoft.Office.Interop.Outlook.ItemEvents_SendEventHandler(_apptEvents_Send); The method _apptEvents_Send then tests on a couple of properties and exits where appropriate. private void _apptEvents_Send(ref bool Cancel) { if (!_Qualified) { MessageBox.Show("Meeting has not been qualified", "Not Qualified Meeting", MessageBoxButtons.OK, MessageBoxIcon.Information); chkQualified.Focus(); Cancel = true; } } The problem that we're having is that some users' messages get sent twice. Once when the meeting is sent and a second time when the user re-opens outlook. I've looked for memory leaks, thinking that something might not be getting disposed of properly, and have added explicit object disposal on all finally calls to try and make sure resources are managed, but still getting the functionality incosistently across the organization. i.e. I never encountered the problem during development, nor other developers during testing. All users are up to date on framework (3.5 SP1) and Hotfixes for Outlook. Does anyone have any ideas on what might be causing this? Any ideas anyone might have would be greatly appreciated.

How to convert a byte array of 19200 bytes in size where each byte represents 4 pixels (2 bits per p

- by Klinger

I am communicating with an instrument (remote controlling it) and one of the things I need to do is to draw the instrument screen. In order to get the screen I issue a command and the instrument replies with an array of bytes that represents the screen. Below is what the instrument manual has to say about converting the response to the actual screen: The command retrieves the framebuffer data used for the display. It is 19200 bytes in size, 2-bits per pixel, 4 pixels per byte arranged as 320x240 characteres. The data is sent in RLE encoded form. To convert this data into a BMP for use in Windows, it needs to be turned into a 4BPP. Also note that BMP files are upside down relative to this data, i.e. the top display line is the last line in the BMP. I managed to unpack the data, but now I am stuck on how to actually go from the unpacked byte array to a bitmap. My background on this is pretty close to zero and my searches have not revealed much either. I am looking for directions and/or articles I could use to help me undestand how to get this done. Any code or even pseudo code would also help. :-) So, just to summarize it all: How to convert a byte array of 19200 bytes in size, where each byte represents 4 pixels (2 bits per pixel), to a bitmap arranged as 320x240 characters. Thanks in advance.

SFINAE and detecting if a C++ function object returns void.

- by Tom Swirly

I've read the various authorities on this, include Dewhurst and yet haven't managed to get anywhere with this seemingly simple question. What I want to do is to call a C++ function object, (basically, anything you can call, a pure function or a class with ()), and return its value, if that is not void, or "true" otherwise. #include <stdio.h> struct Foo { void operator()() {} }; struct Bar { bool operator()() { return false; } }; Foo foo; Bar bar; bool baz() { return false; } void bang() {} const char* print(bool b) { printf(b ? "true, " : "false, "); } template <typename Functor> bool magicCallFunction(Functor f) { return true; // lots of template magic occurs here... } int main(int argc, char** argv) { print(magicCallFunction(foo)); print(magicCallFunction(bar)); print(magicCallFunction(baz)); print(magicCallFunction(bang)); printf("\n"); }

On counting pairs of words that differ by one letter

- by Quintofron

Let us consider n words, each of length k. Those words consist of letters over an alphabet (whose cardinality is n) with defined order. The task is to derive an O(nk) algorithm to count the number of pairs of words that differ by one position (no matter which one exactly, as long as it's only a single position). For instance, in the following set of words (n = 5, k = 4): abcd, abdd, adcb, adcd, aecd there are 5 such pairs: (abcd, abdd), (abcd, adcd), (abcd, aecd), (adcb, adcd), (adcd, aecd). So far I've managed to find an algorithm that solves a slightly easier problem: counting the number of pairs of words that differ by one GIVEN position (i-th). In order to do this I swap the letter at the ith position with the last letter within each word, perform a Radix sort (ignoring the last position in each word - formerly the ith position), linearly detect words whose letters at the first 1 to k-1 positions are the same, eventually count the number of occurrences of each letter at the last (originally ith) position within each set of duplicates and calculate the desired pairs (the last part is simple). However, the algorithm above doesn't seem to be applicable to the main problem (under the O(nk) constraint) - at least not without some modifications. Any idea how to solve this?

Parse a CSV file extracting some of the values but not all.

- by Yallaa

Good day, I have a local csv file with values that change daily called DailyValues.csv I need to extract the value field of category2 and category4. Then combine, sort and remove duplicates (if any) from the extracted values. Then save it to a new local file NewValues.txt. Here is an example of the DailyValues.csv file: category,date,value category1,2010-05-18,value01 category1,2010-05-18,value02 category1,2010-05-18,value03 category1,2010-05-18,value04 category1,2010-05-18,value05 category1,2010-05-18,value06 category1,2010-05-18,value07 category2,2010-05-18,value08 category2,2010-05-18,value09 category2,2010-05-18,value10 category2,2010-05-18,value11 category2,2010-05-18,value12 category2,2010-05-18,value13 category2,2010-05-18,value14 category2,2010-05-18,value30 category3,2010-05-18,value16 category3,2010-05-18,value17 category3,2010-05-18,value18 category3,2010-05-18,value19 category3,2010-05-18,value20 category3,2010-05-18,value21 category3,2010-05-18,value22 category3,2010-05-18,value23 category3,2010-05-18,value24 category4,2010-05-18,value25 category4,2010-05-18,value26 category4,2010-05-18,value10 category4,2010-05-18,value28 category4,2010-05-18,value11 category4,2010-05-18,value30 category2,2010-05-18,value31 category2,2010-05-18,value32 category2,2010-05-18,value33 category2,2010-05-18,value34 category2,2010-05-18,value35 category2,2010-05-18,value07 I've found some helpful parsing examples at http://www.php.net/manual/en/function.fgetcsv.php and managed to extract all the values of the value column but don't know how to restrict it to only extract the values of category2/4 then sort and clean duplicate. The solution needs to be in php, perl or shell script. Any help would be much appreciated. Thank you in advance.

How to get jQuery to find the first list-item, rather than all list-items?

- by ricebowl

I'm trying to implement a basic jQuery infinite carousel. As much for the learning process as for anything else (as a rule I'm not a fan of re-inventing wheels, but...I have to learn somehow, might as well start with the basics). I've managed to get the list to animate left happily enough, but I'm stuck when it comes to selecting the first element of the list. I've tried to use: $('ul#services > li:first'); $('ul#services > li:first-child'); $('ul#services > li').eq([0]); (xhtml below), In each case a console.log(first) (the var name used) returns all of the list-items. Am I doing something blatantly, and obviously, wrong? The eventual plan is to clone the first li, append it to the parent ul, remove the li from the list and allow the list to scroll infinitely. It's just a list of services rather than links so I'm not -at the moment- planning to have scroll or left/right functionality. Current xhtml: <div class="wrapper"> <ul id="services">  <li>one</li ><li>two</li ><li>three</li ><li>four</li ><li>five</li ><li>six</li ><li>seven</li ><li>eight</li ><li>nine</li ><li>ten</li> </ul> </div>

C++ and its type system: How to deal with data with multiple types?

- by sub

"Introduction" I'm relatively new to C++. I went through all the basic stuff and managed to build 2-3 simple interpreters for my programming languages. The first thing that gave and still gives me a headache: Implementing the type system of my language in C++ Think of that: Ruby, Python, PHP and Co. have a lot of built-in types which obviously are implemented in C. So what I first tried was to make it possible to give a value in my language three possible types: Int, String and Nil. I came up with this: enum ValueType { Int, String, Nil }; class Value { public: ValueType type; int intVal; string stringVal; }; Yeah, wow, I know. It was extremely slow to pass this class around as the string allocator had to be called all the time. Next time I've tried something similar to this: enum ValueType { Int, String, Nil }; extern string stringTable[255]; class Value { public: ValueType type; int index; }; I would store all strings in stringTable and write their position to index. If the type of Value was Int, I just stored the integer in index, it wouldn't make sense at all using an int index to access another int, or? Anyways, the above gave me a headache too. After some time, accessing the string from the table here, referencing it there and copying it over there grew over my head - I lost control. I had to put the interpreter draft down. Now: Okay, so C and C++ are statically typed. How do the main implementations of the languages mentioned above handle the different types in their programs (fixnums, bignums, nums, strings, arrays, resources,...)? What should I do to get maximum speed with many different available types? How do the solutions compare to my simplified versions above?

Is it possible to limit outside connections to a subdomain with .htaccess or similar?

- by digidave0205

I host a web application. This application serves static html pages that are refreshed at various intervals. Some as often as every 30 secs. At this time I have about 300 unique pages that are accessed via 300 unique subdomains. Some clients have at most 50 visitors to their unique page and it refreshes every 30 secs, no problem. Other clients have up to 1000 or more visitors to their page. These clients are killing my server. There was no predefined limit upon signup but now I have to impose such a limit to remain afloat financially. I would like to define a finite number of connections allowed for each individual subdomain in my hosting account. Connections attempted out of range of this finite value would either be rejected or redirected. I have access to .htaccess and php.ini. Is something of this nature possible? Oh, I have a dedicated/managed server at 1and1.

Using VB6 to search for existence of DataFile in Outlook

- by Graeme

Hi, I am wanting to write an Add-In for Outlook 2003 which, when Outlook is opened, search for the existence of a datafile called DMSDataStore and if it doesn't exist will install the datafile. I have managed to create the Add-In using VB6 and it runs when I open Outlook. However I haven't found the best/easiest way to search for the existence of the datafile. If the datafile exists it is visible within Outlook under the user's mailbox, much the same as an archive folder is. I would like to be able to search for it by name which is DMSDataFile. I did try - Set tmpInbox = parentFolder.Folders("DMSDataFile") This works OK if the datafile exists but will throw an error if it doesn't. I can create an error handler which will then install the datafile but this doesn't seem like a very tidy way of doing things. I guess I might have to recursively search for the datafile. Can someone let me know what is the best / easiest way to search for the datafile using the name of the datafile and give me some code with which to do it. Thanks G

Custom bean instantiation logic in Spring MVC

- by Michal Bachman

I have a Spring MVC application trying to use a rich domain model, with the following mapping in the Controller class: @RequestMapping(value = "/entity", method = RequestMethod.POST) public String create(@Valid Entity entity, BindingResult result, ModelMap modelMap) { if (entity== null) throw new IllegalArgumentException("An entity is required"); if (result.hasErrors()) { modelMap.addAttribute("entity", entity); return "entity/create"; } entity.persist(); return "redirect:/entity/" + entity.getId(); } Before this method gets executed, Spring uses BeanUtils to instantiate a new Entity and populate its fields. It uses this: ... ReflectionUtils.makeAccessible(ctor); return ctor.newInstance(args); Here's the problem: My entities are Spring managed beans. The reason for this is to inject DAOs on them. Instead of calling new, I use EntityFactory.createEntity(). When they're retrieved from the database, I have an interceptor that overrides the public Object instantiate(String entityName, EntityMode entityMode, Serializable id) method and hooks the factories into that. So the last piece of the puzzle missing here is how to force Spring to use the factory rather than its own BeanUtils reflective approach? Any suggestions for a clean solution? Thanks very much in advance.

batch: replace a line in a text file

- by sasamimasas

I'm trying to replace this line: # forward-socks5 / 127.0.0.1:9050 . with this one: forward-socks5 / 127.0.0.1:9050 . this line belongs to a config file that has to be enabled (UN-commented) by deleting the # sign from the beginning and I could not thought of a better way other than replacing the line with another without the # sign. any other thoughts or ways would be very useful. btw, the spaces before the text are there also.I have pasted the text as it was in the original file. thanks in advance EDIT: I have somehow managed to do the line addition and removing using two peaces of code that I've found. my only problem is that the following code removes every bit of exclamation in the output file! @echo off :Variables SETLOCAL ENABLEDELAYEDEXPANSION set InputFile=config.txt set OutputFile=config-new.txt set _strFind=# forward-socks5 / 127.0.0.1:9050 . set _strInsert= forward-socks5 / 127.0.0.1:9050 . set i=0 :Replace for /f "usebackq tokens=1 delims=[]" %%A in (`find /n "%_strFind%" "%InputFile%"`) do (set _strNum=%%A) for /f "usebackq delims=" %%A in ("%InputFile%") do ( set /a i = !i! + 1 echo %%A>>"%OutputFile%" if [!i!] == [%_strNum%] (echo %_strInsert%>>"%OutputFile%") ) type %OutputFile% | findstr /i /v /c:"%_strFind%">config-new2.txt I was wondering if there is any way to do both the find/delete/add line in one step (not two steps as mine)...

Can't authenticate mobile client with node.js (using passport.js)

- by Pazinio

I'm trying to build some CRUD application with node.js as a back-end API (express) and web-app (backbone) and mobile client (native android) as front-ends.(I'm node.js beginner) My server solution is based on the following great tutorial 'easy-node-authentication'. In my android app I have managed to get the user Google-Token after I completed the authentication step with Google Plus SDK.(mobile to google-plus directly request). I'm trying to understand and find right and elegant way to re-use a given google-token and authenticate again my android user through Google-Plus account to ensure the mobile client holds real token, then add a new entry (id, token, email, name) to my users table DB within my node back-end. The question is: what should be my next step in case I want to keep my back-end without changes? should I send a GET request with the token as a cookie to /auth/google? maybe to /auth/google/callback? another URL? Does this make sense at all? Please note: I'm aware to the fact the mentioned above 'easy-node-auth' solution is based on sessions and cookies. having said that, i'm still trying to understand if there is a convenient way to integrate both (android and node) as it works good for my web-app and node. Thanks in advance.
