  • Service Layer which can switch between Web Service Layer and Data Access Layer

    - by Blake Blackwell
    I am building an application that will function as a client-server application, and also as a disconnected client application. I will be using WPF (browser app for client-server application). When interacting with the server's database, I will need to connect using WCF web services. When connecting with the localized database, I will need to connect using the local db's data access layer. What methods/patterns exist for this sort of architecture?

  • Servlet Session - switch from URL Rewriting to Cookie

    - by lajuette
    Situation: I have a "dumb" Javascript frontend that can contact some kind of SSO middleware (MW). The MW can obtain sessions by issuing requests that contain authentication credentials (username, password). I.e. the session will be created for a certain user. My frontend needs to "restart" the session to gain the user's permissions to the target system. For that i need a valid session cookie. The target system is not under my control (could be a more or less public WFS, WMS, etc.), so i cannot add any SSO mechanism to it. Question: Is it possible to "steal" a Session forging a request which URL contains a valid session ID in the jsessionid parameter? Goal : Issue such a request to a Servlet and make it respond with a Set-Cookie header that contains the same id. That way the frontend joins the session and may do whatever the user, which was used to create the session, is able to do.

  • C/C++ Allegro program causes Windows 7 to switch to Aero Basic

    - by Matt H
    Hi SO, I'm just trying out the allegro library, and here is the code which I've got so far: #include <allegro.h> int main(int argc, char *argv[]) { allegro_init(); // initialize the allegro libraries install_keyboard(); // initialize keyboard functions set_color_depth(16); // set the color depth set_gfx_mode(GFX_AUTODETECT_WINDOWED, 640, 480, 0, 0); // set up 640*480px window BITMAP *pic = NULL; pic = load_bitmap("C:/picture.bmp", NULL); // load the picture blit(pic, screen, 0, 0, 0, 0, 1000, 1000); readkey(); destroy_bitmap(pic); return 0; } END_OF_MAIN() It works fine, but when I run it, while the program's window is open, Windows 7 changes the theme from Aero to Aero basic. If you aren't sure what I mean, this pops up (I got this from Google, which is why it says Vista rather than Windows 7): 1) Why? 2) How can I ensure that this doesn't happen?

  • Trying to set up nested while loops using a boolean switch

    - by thorn100
    First time posting. I'm trying to set up a while loop that will ask the user for the employee name, hours worked and hourly wage until the user enters 'DONE'. Eventually I'll modify the code to calculate the weekly pay and write it to a list, but one thing at a time. The problem is once the main while loop executes once, it just stops. Doesn't error out but just stops. I have to kill the program to get it to stop. I want it to ask the three questions again and again until the user is finished. Thoughts? Please note that this is just an exercise and not meant for any real world application. def getName(): """Asks for the employee's full name""" firstName=raw_input("\nWhat is your first name? ") lastName=raw_input("\nWhat is your last name? ") fullName=firstName.title() + " " + lastName.title() return fullName def getHours(): """Asks for the number of hours the employee worked""" hoursWorked=0 while int(hoursWorked)<1 or int(hoursWorked) > 60: hoursWorked=raw_input("\nHow many hours did the employee work: ") if int(hoursWorked)<1 or int(hoursWorked) > 60: print "Please enter an integer between 1 and 60." else: return hoursWorked def getWage(): """Asks for the employee's hourly wage""" wage=0 while float(wage)<6.00 or float(wage)>20.00: wage=raw_input("\nWhat is the employee's hourly wage: ") if float(wage)<6.00 or float(wage)>20.00: print ("Please enter an hourly wage between $6.00 and $20.00") else: return wage ##sentry variables employeeName="" employeeHours=0 employeeWage=0 booleanDone=False #Enter employee info print "Please enter payroll information for an employee or enter 'DONE' to quit." while booleanDone==False: while employeeName=="": employeeName=getName() if employeeName.lower()=="done": booleanDone=True break print "The employee's name is", employeeName while employeeHours==0: employeeHours=getHours() if employeeHours.lower()=="done": booleanDone=True break print employeeName, "worked", employeeHours, "this week." while employeeWage==0: employeeWage=getWage() if employeeWage.lower()=="done": booleanDone=True break print employeeName + "'s hourly wage is $" + employeeWage

  • How to switch from MSSQL to MySQL for using with Excel pivot

    - by Sim
    Hi all, I have a table that contains sales transaction (~20 mil rows). Previously I used MSSQL and export it to an Excel pivot. Data refresh took 10-15 minutes but still do-able. However, after I migrated to MySQL (using XamppLite & ODBC), it took forever to refresh the data in the Excel pivot. Maybe I didn't optimize the MySQL good enough ? Anyone can share some thoughts 'bout this ? Thanks

  • Reverting CoreData data

    - by ndg
    I have an NSTableView which is populated via a CoreData-backed NSArrayController. Users are able to edit any field they choose within the NSTableView. When they select the rows that they have modified and press a button, the data is sent to a third-party webservice. Provided the webservice accepts the updated values, I want to commit those values to my persistent store. If, however, the webservice returns an error (or simply fails to return), I want the edited fields to revert to their original values. To complicate matters, I have a number of other editable controls, backed by CoreData, which do not need to resort to this behaviour. I believe the solution to this problem revolves around the creation of a secondary Managed Object context, which I would use only for values edited within that particularly NSTableView. But I'm confused as to how the two MOC would interact with each other. What's the best solution to this problem?

  • iPhone TabbarController Switch Transition

    - by user269737
    I've implemented gestures (touchBegan-moved-ended) in order to allow for swiping through my tabs. It works. I'd like to add a slide-from-left and slide-from-right transition. It would be better if it could be part of the gesture if statement which tells me if the swipe is towards the right of left. Since I determine which tab is displayed from that, I could show that specific transition along with the new tab. So my question is this: what's the simplest way to simplement a slide transition at a specific instance. I don't want it to be for the whole tabbarcontrol since this is specifically for the swiping. Thanks for the help, much appreciated. For clarification purposes, this is snippet shows how I'm switching tabs: if(abs(diffx / diffy) > 2.5 && abs(diffx) > HORIZ_SWIPE_DRAG_MIN) { // It appears to be a swipe. if(isProcessingListMove) { // ignore move, we're currently processing the swipe return; } if (mystartTouchPosition.x < currentTouchPosition.x) { isProcessingListMove = YES; self.tabBarController.selectedViewController = [self.tabBarController.viewControllers objectAtIndex:0]; return; } else { isProcessingListMove = YES; self.tabBarController.selectedViewController = [self.tabBarController.viewControllers objectAtIndex:1 ]; return; }

  • SQL Server switch to MySQL/PostgreSQL for startup?

    - by chopps
    I just checked out the licensing for SQL Server and well...i can't afford it since im funding this project myself. I have been tinkering with MySQL and PostgreSQL a bit the past few weeks and at this point I can't really decide which to go with. MySQL has a large user base and lots of people using it so finding out how to do various items will not be to hard o find. I will be using ASP.NET with this project. Anyone have experience going from SQL Server to either of these databases? Is one stronger than the other? Thoughts?

  • How To Switch To A Frame That Appears As A Pop Up Window

    - by chuanl
    I am using the following applications: Selenium 2.0 in C# Firefox I need to write a test that clicks a button and opens a frame as a pop up window. The frame does not have a name nor id. The source code in the frame starts with "html" instead of "frame". However, when you right click on the window, it shows that it is a frame. So, I think it is a frame instead of a window. I have tried the following code, but does not work: driver.SwitchTo().Frame(0) The error I get looks like below: error: No response from server for url http://localhost:7055/hub/session/126a4485-48cb-4230-b0b0-69c4169b1852/element/%7B706f4a88-56a7-4813-af1b-8e137ce676af%7D/click Please help. Thanks.

  • Adobe Air: Read and Write MP3 or JPG from local directory and switch bytes

    - by Max
    I would like to make my local jpg and mp3 files kind of unreadable (without encoding) by just putting the first 100 bytes from the beginning of the file to the end and then saving the file with a .dat extension. I know I have to use the byte array but can't get it work. I would also need then a small function to read that file and put the 100bytes back to the front so that I can play/display the file. It would be great if you could post the whole function because I am quite new to Air so that I fully understand. Thank You!!!!

  • Jetty 7 will not allow me to customize a session cookie path

    - by Bob Obringer
    Using Jetty 7.0.2, I am unable to set a custom session cookie path. I am hosting multiple sites on the same server using apache to proxy requests to the proper context. (replaced http as htp as stackoverflow thinks my multiple links might be spam) <VirtualHost *:80> ServerName context.domain.com ProxyRequests On ProxyPreserveHost Off <Proxy *:80> Order deny,allow Allow from 127.0.0.1 </Proxy> ProxyPass / htp://localhost:8080/context/ ProxyPassReverse / htp://localhost:8080/context/ <Location /> Order allow,deny Allow from all </Location> </VirtualHost> Jetty is running on the same server on port 8080 and my context is available @ /context The user accesses the application @ htp://context.domain.com but jetty is setting the path for the session cookie @ /context. This prevents the browser from accessing the cookie since the the actual path to the context is not being used. I need to override Jetty's default setting to set the cookie for the context, and set the path at the root ( / ). In my Jetty's webdefault.xml I have the following, which is partially working: <context-param> <param-name>org.eclipse.jetty.servlet.SessionCookie</param-name> <param-value>CustomCookieName</param-value> </context-param> <context-param> <param-name>org.eclipse.jetty.servlet.SessionPath</param-name> <param-value>/</param-value> </context-param> The cookie is properly set with a custom name, but it is NOT setting the SessionPath. No matter what I set the value to... it refuses to set a cookie at any path but /context. This has been driving me crazy so any help would be greatly appreciated.

  • Equivalent of Switch Statement in MySql 5

    - by Robert Gowland
    Using MySql 5, I have a task where I need to update one table based on the contents of another table. For example, I need to add 'A1' to table 'A' if table 'B' contains 'B1'. I need to add 'A2a' and 'A2b' to table 'A' if table 'B' contains 'B2', etc.. In our case, the value in table 'B' we're interested is an enum. Right now I have a stored procedure containing a series of statements like: INSERT INTO A SELECT 'A1' FROM B WHERE B.Value = 'B1'; --Repeat for 'B2' -> 'A2a', 'A2b'; 'B3' -> 'A3', etc... Is there a nicer more DRY way of accomplishing this?

  • How does an interpreter switch scope?

    - by Dox
    I'm asking this because I'm relatively new to interpreter development and I wanted to know some basic concepts before reinventing the wheel. I thought of the values of all variables stored in an array which makes the current scope, upon entering a function the array is swapped and the original array put on some sort of stack. When leaving the function the top element of the "scope stack" is popped of and used again. Is this basically right? Isn't swapping arrays (which means moving around a lot of data) not very slow and therefore not used by modern interpreters?

  • Django template tag basic question

    - by ninja123
    It looks like this template tag works like a charm for most people: http://blog.localkinegrinds.com/2007/09/06/digg-style-pagination-in-django/ For some reason I get this error: Caught an exception while rendering: 'is_paginated' I use this template tag in my template like so: {% load digg_paginator %} {% digg_paginator %} Where digg_paginator.py is in my app/templatetags folder and the included template context digg_paginator.html is in my app/templates folder. The queryset that needs pagination is called 'destinations'. If i just specify {% digg_paginator %}, how does it know what variable to paginate?? I feel I am missing something important here or just plain stupid :P Someone please help, or explain to me how this should be done. Thanks

  • how to switch views according to command

    - by Veer
    I've a main view and many usercontrols. The main view contains a two column grid, with the first column filled with a listbox whose datatemplate consists of a usercontrol and the second column filled with another usercontrol. These two usercontrols have the same datacontext. MainView: <Grid> //Column defs ... <ListView Grid.Column="0" ItemSource="{Binding Foo}"> ... <DataTemplate> <Views: FooView1 /> </DataTemplate> </ListView> <TextBlock Text="{Binding Foo.Count}" /> <StackPanel Grid.Column="1"> <Views: FooView2 /> </StackPanel> <Grid> FooView1: <UserControl> <TextBlock Text="{Binding Foo.Title}"> </UserControl> FooView2: <UserControl> <TextBlock Text="{Binding Foo.Detail1}"> <TextBlock Text="{Binding Foo.Detail2}"> <TextBlock Text="{Binding Foo.Detail3}"> <TextBlock Text="{Binding Foo.Detail4}"> </UserControl> I've no IDE here. Excuse me if there is any syntax error When the user clicks on a button. These two usercontrols have to be replaced by another two usercontrols, so the datacontext changes, the main ui remaining the same. ie, FooView1 by BarView1 and FooView2 by BarView2 In short i want to bind this view changes in mainview to my command (command from Button) How can i do this? Also tell me if i could merge the usercontrol pairs, so that only one view exists for each viewmodel ie, FooView1 and FooView2 into FooView and so on...
