  • PubSubHubBub Hubs

    - by PartlyCloudy
    Hi, I'm currently building a live web application based upon the PubSubHubBub protocol. However, I encountered several issues. First, I'm in search of a hub application that I can run on my server. There are several applications, but most of them are not mature yet, or they don't support the 0.3 spec. The official google hub runs on the Google App Engine and can even be executed locally. Unfortunately, "Tasks will not run automatically. Push the 'Run' button to execute each task." This behaviour is useful for debugging and understanding the workflow, but in some live tests, it would be nice not to invoke all tasks manually. Is there a way to tweak the local app engine due automatically run tasks? Next, I have a question concerning the spec itself. The Google reference implementation provides the initial publish method bound to the outpoint uri + /publish. But this is not reflected in the specs. So are there any mature hubs that can be run locally for debugging? Or are there ways to configure the offical google app engine hub to run locally and to execute tasks directly? Thanks in advance

  • Jmeter is not extracting correctly the value with the reg ex extractor.

    - by Chris
    Jmeter is not extracting correctly the value with the reg ex. When I play with this reg ex (NAME="token" \s value="([^"]+?)") in reg ex coach with the following html everything work fine but when adding the reg with a reg ex extrator to the request he doesn't found the value even if it's the same html in output. <HTML>< script type="text/javascript" > function dostuff(no, applicationID) { submitAction('APPS_NAME' , 'noSelected=' + no + '&applicationID=' + applicationID); }< /script> <FORM NAME="baseForm" ACTION="" METHOD="POST"> <input type="hidden" NAME="token" value="fc95985af8aa5143a7b1d4fda6759a74" > <div id="loader" align="center"> <div> <strong style="color: #003366;">Loading...</strong> </div> <img src="images/initial-loader.gif" align="top"/> </div> <BODY ONLOAD="dostuff('69489','test');"> From the reg ex extractor reference name: token Regex: (NAME="token" \s value="([^"]+?)") template : $2$ match no.:1 Default value: wrong-token The request following my the POST of the previous code is returning : POST data: token=wrong-token in the next request in the tree viewer. But when I check a the real request in a proxy the token is there. Note : I tried the reg ex without the bracket and doesn't worked either. Do anybody have a idea whats wrong here ? Why jmeter can't find my token with the reg ex extrator ?

  • Mac CoreLocation Services does not ask for permissions

    - by Ryan Nichols
    I'm writing a Mac App that needs to use CoreLocation services. The code and location works fine, as long as I manually authenticate the service inside the security preference pane. However the framework is not automatically popping up with a permission dialog. The documentation states: Important The user has the option of denying an application’s access to the location service data. During its initial uses by an application, the Core Location framework prompts the user to confirm that using the location service is acceptable. If the user denies the request, the CLLocationManager object reports an appropriate error to its delegate during future requests. I do get an error to my delegate, and the value of +locationServicesEnabled is correct on CLLocationManager. The only part missing is the prompt to the user about permissions. This occurs on my development MPB and a friends MBP. Neither of us can figure out whats wrong. Has anyone run into this? Relevant code: _locationManager = [CLLocationManager new]; [_locationManager setDelegate:self]; [_locationManager setDesiredAccuracy:kCLLocationAccuracyKilometer]; ... [_locationManager startUpdatingLocation]; UPDATE: Answer It seems there is a problem with Sandboxing in which the CoreLocation framework is not allowed to talk to com.apple.CoreLocation.agent. I suspect this agent is responsible for prompting the user for permissions. If you add the Location Services Entitlement (com.apple.security.personal-information.location) it only gives your app the ability to use the CL framework. However you also need access to the CoreLocation agent to ask the user for permissions. You can give your app access by adding the entitlement 'com.apple.security.temporary-exception.mach-lookup.global-name' with a value of 'com.apple.CoreLocation.agent'. Users will be prompted for access automatically like you would expect. I've filed a bug to apple on this already.

  • Sort and limit queryset by comment count and date using queryset.extra() (django)

    - by thornomad
    I am trying to sort/narrow a queryset of objects based on the number of comments each object has as well as by the timeframe during which the comments were posted. Am using a queryset.extra() method (using django_comments which utilizes generic foreign keys). I got the idea for using queryset.extra() (and the code) from here. This is a follow-up question to my initial question yesterday (which shows I am making some progress). Current Code: What I have so far works in that it will sort by the number of comments; however, I want to extend the functionality and also be able to pass a time frame argument (eg, 7 days) and return an ordered list of the most commented posts in that time frame. Here is what my view looks like with the basic functionality in tact: import datetime from django.contrib.comments.models import Comment from django.contrib.contenttypes.models import ContentType from django.db.models import Count, Sum from django.views.generic.list_detail import object_list def custom_object_list(request, queryset, *args, **kwargs): '''Extending the list_detail.object_list to allow some sorting. Example: http://example.com/video?sort_by=comments&days=7 Would get a list of the videos sorted by most comments in the last seven days. ''' try: # this is where I started working on the date business ... days = int(request.GET.get('days', None)) period = datetime.datetime.utcnow() - datetime.timedelta(days=int(days)) except (ValueError, TypeError): days = None period = None sort_by = request.GET.get('sort_by', None) ctype = ContentType.objects.get_for_model(queryset.model) if sort_by == 'comments': queryset = queryset.extra(select={ 'count' : """ SELECT COUNT(*) AS comment_count FROM django_comments WHERE content_type_id=%s AND object_pk=%s.%s """ % ( ctype.pk, queryset.model._meta.db_table, queryset.model._meta.pk.name ), }, order_by=['-count']).order_by('-count', '-created') return object_list(request, queryset, *args, **kwargs) What I've Tried: I am not well versed in SQL but I did try just to add another WHERE criteria by hand to see if I could make some progress: SELECT COUNT(*) AS comment_count FROM django_comments WHERE content_type_id=%s AND object_pk=%s.%s AND submit_date='2010-05-01 12:00:00' But that didn't do anything except mess around with my sort order. Any ideas on how I can add this extra layer of functionality? Thanks for any help or insight.

  • Sql Serve - Cascade delete has multiple paths

    - by Anders Juul
    Hi all, I have two tables, Results and ComparedResults. ComparedResults has two columns which reference the primary key of the Results table. My problem is that if a record in Results is deleted, I wish to delete all records in ComparedResults which reference the deleted record, regardless of whether it's one column or the other (and the columns may reference the same Results row). A row in Results may deleted directly or through cascade delete caused by deleting in a third table. Googling this could indicate that I need to disable cascade delete and rewrite all cascade deletes to use triggers instead. Is that REALLY nessesary? I'd be prepared to do much restructuring of the database to avoid this, as my main area is OO programming, and databases should 'just work'. It is hard to see, however, how a restructuring could help as I would just move the problem around... Or am I missing something? I am also a bit at a loss as to why my initial construct should even be a problem for the Sql Server?! Any comments welcome and much appreciated! Anders, Denmark

  • Allow selection of readonly files from SaveFileDialog?

    - by Andy Dent
    I'm using Microsoft.Win32.SaveFileDialog in an app where all files are saved as readonly but the user needs to be able to choose existing files. The existing files being replaced are renamed eg: blah.png becomes blah.png-0.bak, blah.png-1.bak and so on. Thus, the language for the OverwritePrompt is inappropriate - we are not allowing them to overwrite files - so I'm setting dlog.OverwritePrompt = false; The initial filenames for the dialog are generated based on document values so for them, it's easy - we rename the candidate file in advance and if the user cancels or chooses a different name, rename it back again. When I delivered the feature, testers swiftly complained because they wanted to repeatedly save files with names different from the agreed workflow (those goofy, playful guys!). I can't figure out a way to do this with the standard dialogs, in a way that will run safely on both XP (for now) and Windows 7. I was hoping to hook into the FileOK event but that is called after I get a warning dialog: |-----------------------------------------| | blah.png | | This file is set to read-only. | | Try again with a different file name. | |-----------------------------------------|

  • Browser freeze while ajax call in action

    - by kaivalya
    I have a ASP.NET Web App. I notice that while a simple ajax call(see below) is in process, web application does not respond to any action that I try on a different browser. $.ajax({ type: "GET", async: true, url: "someurl", dataType: "text", cache: false, success: function(msg){ CheckResponse(msg); } }); This happens when I open two firefox or two IE. I run the function that does the ajax call on first browser and till the response of the ajax is returned, I cannot do anything on the second browser on the same site. No breakpoints are hit on the server from the second browser till initial ajax is completed. It hangs for any click etc.. The hang on the second browser ends immediately after the ajax call is completed on the first one. This behavior is not observed if I try the same on IE and Firefox side by side. Only happen with IE & IE or FF & FF side by side Appreciate if you can help me see what I am missing here.

  • does anyone know of good delphi docking components?

    - by X-Ray
    we'd like to add movable panels to an application. presently we've used DevExpress docking library but have found them to be disappointingly quirky & difficult to work with. it also has some limitations that aren't so great. auto-hide, pinning, and moving of pages by drag-and-drop are all features we'd like to use. the built-in delphi docking doesn't seem to be full-featured enough to do the things we need (also see sample below). perhaps i should dig deeper into delphi's docking abilities...my initial impression is that they seem very toolbar-oriented rather than something i can drop a frame into. i'm not experienced at docking topics. my only experience has been with the DevExpress docking library where i needed to programmatically create & dock panels. is it my imagination or are DevExpress's products unduly difficult to use/learn? the DevExpress Ribbon Bar component compared to the d2009 Ribbon Bar was certainly a useful experience. i will migrate to the d2009 Ribbon Bar as soon as convenient to do so. it was refreshingly straight-forward to learn and use. a sharp contrast compared to the DevExpress equivalent. if it takes 4x as longer to make it using the DevExpress equivalent, it's time to change direction. what would you suggest in regard to the docking library? thank you for your suggestions/comments!

  • Starting with versioning mysql schemata without overkill. Good solutions?

    - by tharkun
    I've arrived at the point where I realise that I must start versioning my database schemata and changes. I consequently read the existing posts on SO about that topic but I'm not sure how to proceed. I'm basically a one man company and not long ago I didn't even use version control for my code. I'm on a windows environment, using Aptana (IDE) and SVN (with Tortoise). I work on PHP/mysql projects. What's a efficient and sufficient (no overkill) way to version my database schemata? I do have a freelancer or two in some projects but I don't expect a lot of branching and merging going on. So basically I would like to keep track of concurrent schemata to my code revisions. [edit] Momentary solution: for the moment I decided I will just make a schema dump plus one with the necessary initial data whenever I'm going to commit a tag (stable version). That seems to be just enough for me at the current stage.[/edit] [edit2]plus I'm now also using a third file called increments.sql where I put all the changes with dates, etc. to make it easy to trace the change history in one file. from time to time I integrate the changes into the two other files and empty the increments.sql[/edit]

  • Templates, and C++ operator for logic: B contained by set A

    - by James Morris
    In C++, I'm looking to implement an operator for selecting items in a list (of type B) based upon B being contained entirely within A. In the book "the logical design of digital computers" by Montgomery Phister jr (published 1958), p54, it says: F11 = A + ~B has two interesting and useful associations, neither of them having much to do with computer design. The first is the logical notation of implication... The second is notation of inclusion... This may be expressed by a familiar looking relation, B < A; or by the statement "B is included in A"; or by the boolean equation F11= A + ~B = 1. My initial implementation was in C. Callbacks were given to the list to use for such operations. An example being a list of ints, and a struct containting two ints, min and max, for selection purposes. There, selection would be based upon B = A-min && B <= A-max. Using C++ and templates, how would you approach this after having implemented a generic list in C using void pointers and callbacks? Is using < as an over-ridden operator for such purposes... <ugh> evil? </ugh> (or by using a class B for the selection criteria, implementing the comparison by overloading ?)

  • How to react when asked a question you already know during an interview

    - by DevNull
    The short story:- If you are asked a tough algorithmic/puzzle question during an interview, whose solution is already known to you, do you:- Honestly tell the interviewer that you know this question already? -- this could result in bursting the interviewer's ego and him increasing the complexity level of the subsequent questions. Do an Oscar deserving performance and act as if you are thinking and trying hard and slowly getting to the solution? -- depending on your acting skills, could majorly impress the interviewer making the rest of the interview easier. Long story:- OK, this question comes as a result of what happened to me in a recent telephonic interview that I gave - the interview was supposed to be all algorithmic. The interviewer started with an algorithmic question which I had luckily already seen here on Stackoverflow. The best solution to that problem is not very intuitive and is more of a you-get-it-if-you-know-it kind. Now, just to not disappoint the interviewer too much, I took a few seconds as if I was pondering on the problem and then blurted out the answer which I knew too well having read and admired it on SO already. But I guess that gave it away to the interviewer that I already knew this question and since then, he started asking me for more efficient solutions and I kept coming up with approaches (even if not correct or more efficient, but I did touch a lot of different data structures and algos) and he kept asking for more efficient solutions and generally seemed put off by my initial salvo which was unexpected. What should I have done? Cheers!

  • Dragging a copy of all selected elements from a select box--possible?

    - by Sean
    I have a picklist web interface: a pair of select elements with a pair of buttons (a left-pointing arrow and a right-pointing arrow) between them. Users can move items between the two columns by, eg, selecting one of options in the left column and clicking on the right-pointing arrow. Now I have an enhancement request: someone wants to be able to drag-and-drop items between the two columns instead of clicking a button. The problem with my initial two-select-box setup is that as soon as I click one of the highlighted options to initiate a drag, all of the other selected options are deselected. Using jQuery, I've attached mousedown event handlers to both the select boxes and each individual option that just call preventDefault() on the event object, but this isn't sufficient. On Firefox 3 the clicked-on option loses focus immediately, but all other options are still deseleted, and on IE6 (which I regrettably still have to support) it makes no difference at all. So I thought I could maybe create a reasonable facsimile of a select box using list elements or divs or something. I can create something reasonable-looking that works on Firefox, but on IE6, if I shift-click on an element of my pseudo-select object (in order to select a range of options), IE selects all of the text between where I click and the last place I clicked. Again, I've attached preventDefault-ing mousedown, mouseup, and click handlers to all of the elements involved, but it doesn't help. I've even tried overlaying transparent divs over both my original select boxes and my pseudo-select objects, thinking to intercept mouse clicks and manage the selections manually, but I can't make it work on IE. If I use a select box, I can't prevent clicks from changing the selection, and if I use text that just looks like a select element, I can't prevent it from selecting a range of text on a shift-click. Is there some general solution, or am I just out of luck?

  • Cache consistency & spawning a thread

    - by Dave Keck
    Background I've been reading through various books and articles to learn about processor caches, cache consistency, and memory barriers in the context of concurrent execution. So far though, I have been unable to determine whether a common coding practice of mine is safe in the strictest sense. Assumptions The following pseudo-code is executed on a two-processor machine: int sharedVar = 0; myThread() { print(sharedVar); } main() { sharedVar = 1; spawnThread(myThread); sleep(-1); } main() executes on processor 1 (P1), while myThread() executes on P2. Initially, sharedVar exists in the caches of both P1 and P2 with the initial value of 0 (due to some "warm-up code" that isn't shown above.) Question Strictly speaking – preferably without assuming any particular CPU – is myThread() guaranteed to print 1? With my newfound knowledge of processor caches, it seems entirely possible that at the time of the print() statement, P2 may not have received the invalidation request for sharedVar caused by P1's assignment in main(). Therefore, it seems possible that myThread() could print 0. References These are the related articles and books I've been reading. (It wouldn't allow me to format these as links because I'm a new user - sorry.)

  • Can I make any ASP.NET/HTML element into form-data that posts back to the server?

    - by Giffyguy
    I am using Javascript to alter the innerHTML attribute of a <td> and I need to get that info back in the form submittal. The <td> corrosponds to an <asp:TableCell> on the server-side, where the Text attribute is set to an initial value. The user cannot enter the value in this particular field. Instead, its value is set by me (via client-side script) based on actions that the user performs. But this field is useless to me if I can't see its value on the server-side as well. I'd like to avoid using a read-only textbox, because those are difficult to resize dynamically. Can an <asp:Label> be used as form data? Is there any way to achive this without letting the user manually enter the data? Or is there a simpler way to store a string as a variable somewhere and send it back as form-data?

  • When developing a Microsoft Office Add-In (for Word), is it possible to store hidden metadata inform

    - by leftend
    I am trying to store metadata (basically a unique id) along with each cell of a table in a Word document. Currently, for the add-in I'm developing, I am querying the database, and building a table inside the Word document using the data that is retrieved. I want to be able to save any of the user's edits to the document, and persist it back to the database. My initial thought was to store a unique id along with each cell in the table so that I would be able to tell which records to update. I would also like to store some sort of "isChanged" flag within each cell so that I could tell which cells were changed. I found that I could add the needed information into the "ID" property of the cell - however, that information was not retained if the user saved the document, closed it, and re-opened it. I then tried storing the data by adding a data to the "Fields" collection - but that did not work and threw a runtime error. Here is the code that I tried: object t1 = Word.WdFieldType.wdFieldEmpty; object val = "myValue: " + counter; object preserveFormatting = true; tbl.Cell(i, j).Range.Fields.Add(tbl.Cell(i, j).Range, ref t1, ref val, ref preserveFormatting); This compiles fine, but throws this runtime error "This command is not available". So, is this possible at all? Or am I headed in the wrong direction? Thanks in advance.

  • How to override the default init.tcl

    - by Sean Murphy
    I'm working on a project where I want to make use of TCL as the command interpreter. I have a working c library object which I can load from within the tcl shell but my problem is finding a way to automatically do this while starting a tclsh. Essentially my ultimate goal is to be able to run a script and have it load my library and run some initial startup tcl code before dropping me back to the tclsh command prompt in interactive mode. e.g. tclsh -f myscript.tcl --then-switch-to-interactive or EXPORT TCLINIT=myscript.tcl tclsh The basic goal is to avoid having to distribute tclsh but rather rely in local user installations of tcl. All I would like to distribute is my library, a startup script and a shell command to launch the tclsh with the library preloaded. I've tried using the environment variables TCLINIT and TCL_LIBRARY but they seem to have no effect. The only workable solutions I've found so far are to add "source myscript.tcl" to either the end of /usr/share/tcltk/tcl8.5.init.tcl or ~/.tclshrc However both of these "solutions" are non perfect as they require modification of the default users workspace. It strikes me that there must be a way to handle this in TCL, but my research so far hasn't yielded anything. Does anyone have any suggestions?

  • Delay before playing embedded mp3 in Actionscript / Flex 3

    - by lacker
    I am embedding an mp3 into my Flex project for use as a sound effect, but I am finding that every time I play it, there is a delay of about half a second from when I call .play() to when you can hear the sound. This makes it weird because I want the sound effects to sync to game events. My mp3 itself is only about a fifth of a second long so it isn't because of the contents of the mp3. I'm embedding with [Embed(source="assets/Tock.mp3")] [Bindable] public static var TockSound:Class; public var tock_sound:SoundAsset; and then playing with if (tock_sound == null) { tock_sound = new TockSound() as SoundAsset; } Alert.show("tock"); tock_sound.play(); I know there's a delay because the sound plays about a half second after the Alert displays. I did consider that maybe it was the initial loading time of constructing the TockSound, but the delay is there on all the subsequent calls as well. How can I avoid this delay on playing a sound? Update: It turns out this delay is only present when playing the swf on Linux. I believe it is a Linux-specific flaw in Adobe's flash player.

  • multiple redirect??

    - by Ryan Pitts
    Ok, i won't go into the full details (too much to explain) but here is what i am trying to do. I have a button on a webpage (we'll call page-1) that links to a page (we'll call it page-2). This page opens in the same window. However, i need the page (page-2) that opens to open up a new window with another page (we'll call this one page-3) when it loads. So virtually when you click the initial button (on page-1) it will go to a new page (page-2) AND a window will open as well with a different page (page-3). This is where it gets tricky. I need page-2 to automatically redirect back to page-1 after it launches page-3. Is this possible and if so, how?? Could it be a JQuery thing? Please just give some answers...i know this is way crazy and a huge workaround - but this is my last resort for this particular website. I have to do it this way because of the lack of control over some of the code.

  • vs10 not deploying all required files - then not over-writing updated files

    - by justSteve
    I'm in the habit of deploying to alternating folders (/inetpub/wwwroot/mySite & /inetpub/wwwroot/mySite2) so if something unexpected happens with the deploy i can quickly swap back to a previous version just by changing the path in IIS So i was deploying an MVC2 webapp to a empty folder figuring that VS would send up all the files it needs. Not even close. Initially, it didn't even upload a couple required nHibernate.dlls. Later, after manually copying files referenced in the thrown exceptions, i just copied all the files from the previous compile and then re-published over the top expecting VS to over-write the changed files. Failed that too. No reports of errors by VS....just failed to over-write a number of pre-existing (but changed/updated) files. Hard to believe these kinds of errors (and lack of feedback that errors were encountered) in a state of the art tool like VS. Clearly, I'm doing something wrong. I'm using VisualSVN for source control and connect to my colocated server via a VPN-based mapped network drive (so I can use FileSystem to publish). (both of which can complicate file properties) VS08 had more choices for which files it would send up - i found i needed to use the 'All files in source' on an initial deployment, the 'Replace Matching'. If I choose 'delete all existing...' I'd be back to square 1 and have to deploy with the 'All files in source project folder'. But VS10 doesn't have the 'All files in source project folder. I ended up manually copying the files - which seems not right in the extreme. Are these known issues others have to deal with? What's best practice for deploying a web-app? thx

  • How to adjust size of programatically created Bitmap to match text drawn on it?

    - by TooFat
    I have the following .ashx page that takes some query string parameters and returns a bitmap with the specified text written on it. The problem I have is that I am currently just manually setting the initial size of the bitmap at 100 X 100 when what I really want is to have the bitmap be just big enough to include all the text that was written to it. How can I do this? public void ProcessRequest (HttpContext context) { context.Response.ContentType = "image/png"; string text = context.Request.QueryString["Text"]; //set FontName string fontName; if (context.Request.QueryString["FontName"] != null) { fontName = context.Request.QueryString["FontName"]; } else { fontName = "Arial"; } //Set FontSize int fontEms; if (context.Request.QueryString["FontSize"] != null) { string fontSize = context.Request.QueryString["FontSize"]; fontEms = Int32.Parse(fontSize); } else { fontEms = 12; } //Set Font Color System.Drawing.Color color; if (context.Request.QueryString["FontColor"] != null) { string fontColor = context.Request.QueryString["FontColor"]; color = System.Drawing.ColorTranslator.FromHtml(fontColor); context.Response.Write(color.ToString()); } else { color = System.Drawing.Color.Red; } using (System.Drawing.Text.PrivateFontCollection fnts = new System.Drawing.Text.PrivateFontCollection()) using (System.Drawing.FontFamily fntfam = new System.Drawing.FontFamily(fontName)) using (System.Drawing.SolidBrush brush = new System.Drawing.SolidBrush(color)) using (System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(100, 100)) { using (System.Drawing.Font fnt = new System.Drawing.Font(fntfam, fontEms)) { fnts.AddFontFile(System.IO.Path.Combine(@"C:\Development\Fonts\", fontName)); System.Drawing.Graphics graph = System.Drawing.Graphics.FromImage(bmp); graph.DrawString(text, fnt, brush, new System.Drawing.Point(0, 0)); string imgPath = System.IO.Path.Combine(@"C:\Development\MyPath\Images\Text", System.IO.Path.GetRandomFileName()); bmp.Save(imgPath); context.Response.WriteFile(imgPath); } } }

  • Proper use of HttpRequestInterceptor and CredentialsProvider in doing preemptive authentication with

    - by Preston
    I'm writing an application in Android that consumes some REST services I've created. These web services aren't issuing a standard Apache Basic challenge / response. Instead in the server-side code I'm wanting to interrogate the username and password from the HTTP(S) request and compare it against a database user to make sure they can run that service. I'm using HttpClient to do this and I have the credentials stored on the client after the initial login (at least that's how I see this working). So here is where I'm stuck. Preemptive authenticate under HttpClient requires you to setup an interceptor as a static member. This is the example Apache Components uses. HttpRequestInterceptor preemptiveAuth = new HttpRequestInterceptor() { @Override public void process( final HttpRequest request, final HttpContext context) throws HttpException, IOException { AuthState authState = (AuthState) context.getAttribute(ClientContext.TARGET_AUTH_STATE); CredentialsProvider credsProvider = (CredentialsProvider) context.getAttribute( ClientContext.CREDS_PROVIDER); HttpHost targetHost = (HttpHost) context.getAttribute(ExecutionContext.HTTP_TARGET_HOST); if (authState.getAuthScheme() == null) { AuthScope authScope = new AuthScope(targetHost.getHostName(), targetHost.getPort()); Credentials creds = credsProvider.getCredentials(authScope); if (creds != null) { authState.setAuthScheme(new BasicScheme()); authState.setCredentials(creds); } } } }; So the question would be this. What would the proper use of this be? Would I spin this up as part of the application when the application starts? Pulling the username and password out of memory and then using them to create this CredentialsProvider which is then utilized by the HttpRequestInterceptor? Or is there a way to do this more dynamically?

    Hello everyone, I am using VSTS 2008 + C# + .Net 3.5 + ADO.Net. Here is my code and related error message. The error message says, @Param1 is not supplied, but actually it is supplied in my code. Any ideas what is wrong? System.Data.SqlClient.SqlException: Procedure or function 'Pr_Foo' expects parameter '@Param1', which was not supplied. class Program { private static SqlCommand _command; private static SqlConnection connection; private static readonly string _storedProcedureName = "Pr_Foo"; private static readonly string connectionString = "server=.;integrated Security=sspi;initial catalog=FooDB"; public static void Prepare() { connection = new SqlConnection(connectionString); connection.Open(); _command = connection.CreateCommand(); _command.CommandText = _storedProcedureName; _command.CommandType = CommandType.StoredProcedure; } public static void Dispose() { connection.Close(); } public static void Run() { try { SqlParameter Param1 = _command.Parameters.Add("@Param1", SqlDbType.Int, 300101); Param1.Direction = ParameterDirection.Input; SqlParameter Param2 = _command.Parameters.Add("@Param2", SqlDbType.Int, 100); portal_SiteInfoID.Direction = ParameterDirection.Input; SqlParameter Param3 = _command.Parameters.Add("@Param3", SqlDbType.Int, 200); portal_RoleInfoID.Direction = ParameterDirection.Input; _command.ExecuteScalar(); } catch (Exception e) { Console.WriteLine(e); } } static void Main(string[] args) { try { Prepare(); Thread t1 = new Thread(Program.Run); t1.Start(); t1.Join(); Dispose(); } catch (Exception ex) { Console.WriteLine(ex.Message + "\t" + ex.StackTrace); } } } Thanks in advance, George

  • ECM (Niche Vs Mass Market)

    - by Luj Reyes
    Hi Everyone, I recently started a little company with a couple of guys. Ours is the typical startup, a lot of ideas, dreams, talent and work hours :P. Our initial business plan was to develop a DM (Document Manager) with several features found on DropBox and other tools but with a big differentiator. Then we got in the team this Business Guy (I must say that several of us could be called 'Business Guys' but we are mainly hackers, he is just Another 'Networking Guy'), and along with him came this market analysis for a DM aimed at a very specific and narrow niche. We have many elements to believe in his market study and the idea is the classic "The market is X million, so if we grab a 10%...", and the market is really there to grab because all big providers deemed it too little and fled, let's say that the market is 5 million USD and demand very specific features. If we decide to go for this niche product we face a sales cycle of about 7 months, and the main goal of these revenue is to develop more ambitious projects. (Institutional VC is out of the question if you want to keep a marginal ownership of your company in my country). The only overlap between the niche and the mass market product features is the ability to store documents; everything else requires that we focus all of our efforts towards one or the other. I've studied a lot about the differences between Mass and Niche Markets, but I want to hear from people with actual experience. So everything comes down to this: If you have a really “saleable” idea what is the right thing to do: to go for the niche or go for the big prize and target primarily the mass market? Thanks for your input

  • database design suggestion needed

    - by JMSA
    I need to design a table for daily sales of pharmaceutical products. There are hundreds of types of products available {Name, code}. Thousands of sales-persons are employed to sell those products{name, code}. They collect products from different depots{name, code}. They work in different Areas - Zones - Markets - Outlets, etc. {All have names and codes} Each product has various types of prices {Production Price, Trade Price, Business Price, Discount Price, etc.}. And, sales-persons are free to choose from those combination to estimate the sales price. The problem is, daily sales requires huge amount of data-entry. Within couple of years there may be gigabytes of data (if not terabytes). If I need to show daily, weekly, monthly, quarterly and yearly sales reports there will be various types of sql queries I shall need. This is my initial design: Product {ID, Code, Name, IsActive} ProductXYZPriceHistory {ID, ProductID, Date, EffectDate, Price, IsCurrent} SalesPerson {ID, Code, Name, JoinDate, and so on..., IsActive} SalesPersonSalesAraeaHistory {ID, SalesPersonID, SalesAreaID, IsCurrent} Depot {ID, Code, Name, IsActive} Outlet {ID, Code, Name, AreaID, IsActive} AreaHierarchy {ID, Code, Name, PrentID, AreaLevel, IsActive} DailySales {ID, ProductID, SalesPersonID, OutletID, Date, PriceID, SalesPrice, Discount, etc...} Now, apart from indexing, how can I normalize my DailySales table to have a fine grained design that I shall not need to change for years to come? Please show me a sample design of only the DailySales data-entry table (from which all types of reports would be queried) on the basis of above information. I don't need a detailed design advice. I just need an advice regarding only the DailySales table. Is there any way to break this particular table to achieve granularity?

  • Error handling in PHP

    - by Industrial
    Hi guys, We're building a PHP app based on Good old MVC (codeigniter framework) and have run into trouble with a massive chained action that consists of multiple model calls, that together is a part of a big transaction to the database. We want to be able to do a list of actions and get a status report of each one back from the function, whatever the outcome is. Our first initial idea was to utilize the exceptions of PHP5, but since we want to also need status messages that doesnt break the execution of the script, this was our solution that we came up with. It goes a little something like this: $sku = $this->addSku( $name ); if ($sku === false) { $status[] = 'Something gone terrible wrong'; $this->db->trans_rollback(); return $status; } $image= $this->addImage( $filename); if ($image=== false) { $error[] = 'Image could not be uploaded, check filesize'; $this->db->trans_rollback(); return $status; } Our controller looks like this: $var = $this->products->addProductGroup($array); if (is_array($var)) { foreach ($var as $error) { echo $error . '<br />'; } } It appears to be a very fragile solution to do what we need, but it's neither scalable, neither effective when compared to pure PHP exceptions for instance. Is this really the way that this kind of stuff generally is handled in MVC based apps? Thanks!
