  • Loading from pickled data causes database error with new saves

    - by hibbie
    In order to save time moving data I pickled some models and dumped them to file. I then reloaded them into another database using the same exact model. The save worked fine and the objects kept their old id which is what I wanted. However, when saving new objects I run into nextval errors. Not being very adept with postgres, I'm not sure how to fix this so I can keep old records with their existing ID while being able to continue adding new data. Thanks, Thomas

  • Detect if Visual Studio Test is running

    - by RTigger
    Is there an easy way to detect if you're running in the context of a Visual Studio Test as opposed to debug or release? Here's the scenario - we have a factory class that we use heavily throughout our existing codebase, and I figured instead of refactoring it out in each class so we can substitute the default factory with one that would return mock/fake objects, I could add something in the factory class itself to return those mock objects if it detects it's running in "test" mode.

  • suddenly can't connect to Windows 7 PC from xbmc

    - by Damon
    I have xbmc installed on a softmodded classic xbox and all of a sudden I cannot connect to the shared folders on my Windows 7 PC. Well, it can connect but it wants a username and password, but none exist on my computer. It's been several weeks since I last used it, but it was working fine then! and no particular changes I can think of aside from I guess a few Windows updates. I've seen reference online to Windows Live essentials causing issues with file sharing, but I don't even have that installed. And I made sure to tick 'turn off password protected sharing' in my advanced network setup. I had the guest account turned off and working fine before, and tried turning it on but no luck. I can access my shared folders fine from other Computers and a ps3. I've read a couple threads of similar situations on various folders and none of their solutions have worked.

  • Repeating a object that only occurs couple of times and has different values with htmlagilitypack c#.

    - by dtd
    I have a problem I cant seem to solve here. Lets say I have some html like beneth here that I want to parse. All this html is within one list on the page. And the names repeat themself like in the example I wrote. <li class = "seperator"> a date </li> <li class = "lol"> some text </li> <li class = "lol"> some text </li> <li class = "lol"> some text </li> <li class = "seperator"> a new date </li> <li class = "lol"> some text </li> <li class = "seperator"> a nother new date </li> <li class = "lol"> some text </li> <li class = "lol"> some text </li> I did manage to use htmlagility pack to parse every li object seperate, and almost formating it how I want. My print atm looks something like this: "a date" "some text" "some text" "some text" "some text" "a new date" "some text" "a nother new date " "some text" "some text" "some text" What I want to achive: "a date" "some text" "a date" "some text" "a date" "some text" "a date" "some text" "a new date" "some text" "a nother new date " "some text" "a nother new date " "some text" "a nother new date " "some text" But the problem is that beneath every seperator, the count of every lol object may vary. So one day, the webpage may have one lol object beneth date 1, and the next day it may have 10 lol objects. So I am woundering if there is an smart/easy way to somehow count the number of lol objects in between the seperators. Or if there is another way to figure this out? Within for example htmlagilitypack. And yes, I need the correct date in front of every lol object, not just infront the first one. This would have been a pice of cake if the seperator class would have ended beneath the last lol object, but sadly that is not the case... I dont think that I need to paste my code here, but basicly what I do is to parse the page, extract the seperators and lol objects and add them to a list, where I split them up to seperator and lol objects. Then I print it out to a file and since the seperator only occure 3 times(in the example) I will only get out 3 seperate dates.

  • Django context processor gets AnonymousUser

    - by myfreeweb
    instead of User. def myview(request): return render_to_response('tmpl.html', {'user': User.objects.get(id=1}) works fine and passes User to template. But def myview(request): return render_to_response('tmpl.html', {}, context_instance=RequestContext(request)) with a context processor def user(request): from django.contrib.auth.models import User return {'user': User.objects.get(id=1)} passes AnonymousUser, so I can't get the variables I need :( What's wrong?

  • Checking an empty Core Data relationship (SQLite)

    - by rwat
    I have a to-many relationship in my data model, and I'd like to get all the objects that have no corresponding objects in the relationship. For example: Customer - Purchases I want to get all Customers that have 0 Purchases. I've read somewhere that I could use "Purchases[SIZE] = 0", but this gives me an unsupported function expression error, which I think means it doesn't work with a SQLite backing store (which I don't want to switch from, due to some performance constraints). Any ideas?

I an sharing this printer on all clients with windows XP. All other computers are fine only 1 HP laptop.

  • "Device not ready" on a network share in Windows 7

    - by user60689
    I have two computers C1 and C2 runing Windows 7 and both of them are members in a domain. On C1 I have an USB hard-disk which I shared for the users U1 and U2 giving them Read-Only permissions on the entire drive. However, even if I can see and browse the hard-disk localy (IOW from C1), from the other computer (C2) where I'm logged with U1, trying to access the C1's shared device, the C2's Windows 7 throws an error saying "Device Not Ready". Why? How can I fix this? PS: Tried to un-share and re-share again. No luck.

  • Boost any usage

    - by Ockonal
    Hello, how can I insert my own class objects into ptr_map from boost. The objects are templated so I can't use some static typename in the map. So I did: ptr_map<string, any> someMap; My class inherits the boost::noncopyable. someMap.insert("Test", new MyClass()); The error is: error: no matching function for call to ‘boost::ptr_map.

  • Trouble adding event listeners via JavaScript

    - by Jack Roscoe
    Currently I have a function which loops to create multiple HTML objects. Each time an object is created, I want to add an onClick function listener to that object so that I can trigger a function when each one is clicked. What's the best way to do this? Here's the code which creates my objects: RenderMultipleChoice:function() { this.c = paper.rect(this.x, this.y, this.shapeWidth, this.shapeHeight); }

  • Two method for linking a object using GCC ?

    - by bluewater
    I've known that I should use -l option for liking objects using GCC. that is gcc -o test test.c -L./ -lmy But I found that "gcc -o test2 test.c libmy.so" is working, too. When I use readelf for those two executable I can't find any difference. Then why people use -l option for linking objects? Does it have any advantage?

  • Using build with a has_one association in rails.

    - by espinet
    This is a really noob question but im having trouble finding the answer, is there a way in rails to have 0 or 1 association? For example, I create a user with no objects, than later on create an object for that user. I tried using build with a 'has_one' association but that blew up... The only way I see this working is using 'has_many'. The user is suppose to only have at most one of these objects, is there any way to do this?

    - by mamu
    We have serialized value of some objects persisted. Now we want to make substantial changes to some objects. So what i want to do is load older version of object using old assembly then deserialize and serialize again with newer version of the object. I can have convert method which can transform old object to new one. i have been converting object on fly on deserializer but in this case it's almost new object with same name.

  • MS Access 2007 end user access

    - by LtDan
    I need some good advise. I have used Access for many years and I use Sharepoint but never the two combined. My newly created Access db needs to be shared with many users across the organization. The back end is SQL and the old way to distribute the database would be placing the db on a shared drive, connecting their PC ODBC connections to the SQL db and then they would open the database and have at it. This has become the OLD way. What is the best (and simpliest) way to allow the end users to utilize a frontend for data entry/edit reporting etc. Can I create a link through SharePoint and the user just open it from there. Your good advise is greatly approciated.

  • Repairing a TFS 2005 install or starting anew.

    - by Johan Buret
    Following : Installing Team Foundation Server on a shared database instance We did use a shared database instance setup for TFS 2005, and that was not a good idea, because of the Reporting Service dependency. The reporting instance on the server gives error code 404. What works now Basic source code control. We're able to check in and out source code. What doesn't work : Everything else, including : Opening and creating new team projects. Build automation. Internal bug tracking. Goal setup Having a fully working TFS install, and keeping the history. 1) A full install of TFS 2005 on the same server, but within its own database and reporting instance. 2) Using another server might be an option, but it's really not prefered Downtime should be minimum, my colleagues needs to be able to work on the source Readings I've read the MSDN page about moving/restoring TFS 2005, but I'm still unsure about what to do. Thanks in advance for help
