• VB.NET function that takes other functions as a parameter, and executes them

  - by rob

  Hello, Is there a way in vb.net to create a sub/function that will take as an argument some kind of pointer to another function, and allow this new sub/function to execute the passed function? What I have are 10-12 xml-rpc functions I am calling against a remote server. Each of these functions has different argument lists (one takes 1 string, another might take 3 strings and one int, etc). All of them return an object. As I am calling these, it seems like it should be able to be factored better. For instance, everytime I call any of these functions, I want to test the return value for a session drop, and do something to try and reconnect to the remote system, etc. Using .net 3.5 Thanks! -R

• Man machine interface command syntax and parsing

  - by idimba

  What I want is to add possibility to interact with application, and be able to extract information from application or event ask it to change some states. For that purpose I though of building cli utility. The utility will connect to the application and send user commands (one line strings) to the application and wait for response from the application. The command should contain: - command name (e.g. display-session-table/set-log-level etc.) - optionally command may have several arguments (e.g. log-level=10) The question to choose syntax and to learn parse it fast and correctly. I don't want to reinvent the whell, so maybe there's already an answer out there.

• Haskell as REST server

  - by Dev er dev

  I would like to try Haskell on a smallish project which should be well suited to it. I would like to use it as a backend to a small ajax application. Haskell backend should be able to do authentication (basic, form, whatever, ...), keep track of user session (not much data there except for username) and to dispatch request to handlers based on uri and request type. It should also be able to serialize response to both xml and json format, depending on request parameter. I suppose the handlers are ideally suited for Haskell, since the service is basically stateless, but I don't know where to start for the rest of the story. Searching hackage didn't give me much hints.

• Dynamic Windows Forms Components (Performance problem)

  - by Svisstack

  I have a problem with performance of my code under Windows Forms. Have a form, her layout is depending on constructor data, because he layout must be OnLoad or in Constructor generated.

Anyone help me in this problem? How solve the dynamic form layout problem?

• TooManyRowsAffectedException with encrypted triggers

  - by Jon Masters

  I'm using nHibernate to update 2 columns in a table that has 3 encrypted triggers on it. The triggers are not owned by me and I can not make changes to them, so unfortunately I can't SET NOCOUNT ON inside of them. Is there another way to get around the TooManyRowsAffectedException that is thrown on commit? Update 1 So far only way I've gotten around the issue is to step around the .Save routine with var query = session.CreateSQLQuery("update Orders set Notes = :Notes, Status = :Status where OrderId = :Order"); query.SetString("Notes", orderHeader.Notes); query.SetString("Status", orderHeader.OrderStatus); query.SetInt32("Order", orderHeader.OrderHeaderId); query.ExecuteUpdate(); It feels dirty and is not easily to extend, but it doesn't crater.

• Windbg pseudoregister expansion

  - by Giuseppe Guerrini

  Hi, I am trying to automate a device driver's debug session in Windows XP with Windbg. My device has an "index" register and a "data" register, both memory mapped. The index register must be filled with the internal register's index, and the value can be read from the data register. So, the followind Windbg command prints correctly the value of the internel register 0x4C: !ed [uc] 0xfa000000 0x4c; !dd [uc] 0xfa000004 L1 Now I would like to dump a range of internal registers, but it seems that the alias expansion doesn't work as expected in the !ed command. I am trying this cycle: .for (r $t0=0; @$t0<0x100; r $t0=@$t0+1) { !ed [uc] 0xfa000000 @$t0; !dd [uc] 0xfa000004 L1 } but it seems that the !ed command is ignored, as if @$t0 was expanded in an empty string. Tried "$t0", "@$t0", "${t0}" and "@${t0}", but without success. What am I doing wrong? Thank you in advance

• Improving the speed of php

  - by cast01

  I'm currently working on a website in PHP, and I'm wondering what the best practices/methods are to reduce the time requests take. I've build the site in a modular way, so a page would consist of a number of modules, and each of these would need to request information. For example, I have a cart module, that (if a cart is set) will fetch the cart with the id (stored in a session variable) from the database and return its contents. I have another module that lists categories and this needs to fetch the categories from the database. My system is built with models, and each model might also make a request, for example a category model will make a request to get products in that category.

• Django, Redirecting staff from login to the admin site.

  - by Francisco Gomez

  So my site basically has 2 kinds of ways to login, one of them is for the common users, who get the regular screen that asks them for username and password, the other way its for staff. The staff login should redirect them to the admin site after logging in, but for some reason the redirect doesnt happen, it stays on the same login page. I use this condition on the login view. if user is not None and user.is_active and user.is_staff: auth.login(request,user) return HttpResponseRedirect("/admin/") The admin site its up and running in my url configuration and everything, but i dont know if this is the correct way to redirect to the admin site already on session. Thanks, any help would be appreciated.

• Do minidump files contain the timestamp of the crash?

  - by Roger Lipscombe

  The MiscInfoStream in a minidump file contains the process create time. I'd like to find out how long the process has been running for before the crash. Does a minidump file contain the exception timestamp anywhere? WinDbg on this dump file displays the following, which implies that it's in there somewhere... Debug session time: Tue Dec 29 15:49:20.000 2009 (GMT+0) System Uptime: not available Process Uptime: 0 days 0:33:03.000 Note that today's Mar 15, so this is almost certainly the timestamp of the crash. I'd like a programmatic way to retrieve that value and the "Process Uptime" value. I found the MINIDUMP_MISC_INFO_3 structure, which contains some timezone information, but it doesn't seem to contain the exception time.

  I have a dynamically generated gridview on page with sorting provided in the code behind also. Now i move from page A to page B using a link, this also works fine. But when i press the browser back button and come back to my page A and again try to sort... page A throws an exception... is there a way to program this back button like we program a button normally.. Thanks ` Cannot find column machinename. Description: An unhandled exception occurred during the execution of the current web request.

• Shark tool on iphone crashes

  - by Joey

  Hi, I am trying to use Shark to profile my app. However, it crashes after I hit "stop" and it analyzes and then goes to "load session". Only once when I decided not to select my app but chose to target "everything" did it actually display some trace. However, I could not reproduce this case. Does anyone have any idea what might be going wrong? Could it be something to do with the wrong version of Shark or my SDK or some other detail? I have the latest SDK and am running 3.1.3 on the phone. The various documentation I've found on google or via Apple's docs don't seem to be terribly helpful, so if anyone has found some that's useful, I'd love to see it. Thanks.

• firefox: getting access to the list of tabs/windows to restore on startup

  - by robb

  Sometimes ffox fails to restore the previously open tabs/windows. This might be happening when some of the urls to be opened are no longer reachable (e.g. behind a vpn) or after the underlying OS (Windows) has been forcibly restarted (e.g. to complete an automated patch installation). Anyway, after restarting, can this list of urls be recovered somehow? Say for example, I was daft enough to have clicked on "start new session". Can I still get access to the old list of open urls? There is the browser history of course, but it contains a lot of stuff - the urls that were open when ffox last exited are not obvious. It would be neat if they were marked in some way - tagged for example. .robb

• Is it bad practice to extend the MongoEngine User document?

  - by Soviut

  I'm integrating MongoDB using MongoEngine. It provides auth and session support that a standard pymongo setup would lack. In regular django auth, it's considered bad practice to extend the User model since there's no guarantee it will be used correctly everywhere. Is this the case with mongoengine.django.auth? If it is considered bad practice, what is the best way to attach a separate user profile? Django has mechanisms for specifying an AUTH_PROFILE_MODULE. Is this supported in MongoEngine as well, or should I be manually doing the lookup?

• Having trouble with event creation using the events.create API with the iPhone SDK

  - by MahatmaManic

  I'm using the FBConnect library in my iPhone app, and I'm trying to create Facebook events. After getting a valid session and verifying permissions, I'm using events.create and getting what looks like a valid event ID back from FB in a success response. Oddly the event isn't showing up on my account's Events page either in current or in past events. I thought the problem might be that the event might not include me as an attendee so I followed the successful events.create call with an events.rsvp call to set my status to "attending". That also gets back success from FB, but I'm still not seeing anything show up. Am I missing a step? Is there something other than Create and then RSVP that I need to do, or is there an error with the api/Facebook? I don't think I'm missing any of the required fields for event creation (name and start_time) and I am populating a lot of the other fields in event_info...

• keeping xmphp bot always online

  - by Gunjan

  I created a simple xmpp bot in PHP which connects to google talk server. I basically modified the cli_longrun example. When I run the script in browser the bot comes online and stays online for a while even after I close the tab on which the script was running (as it is just an infinite loop listening for events on the stream). But after a while the bot becomes offline. The question is how do I keep the bot always online. One way I can think of is to run a cron that would disconnect the earlier one and start a new session. But is there a better approch?

• How to fetch message body and attachments in XML format using php/linux from Lotus Domino server?

  - by too

  Has anybody some information about accessing Lotus Domino server to fetch entire mail contents by http(s) requests from php linux server? The article by Andrei Kouvchinnikov describes well how to fetch message list in notes mail folders; after obtaining session id during login one can for example select top 100 messages by calling: https://your.server.domain/mail_db/mailbox.nsf/($Inbox)?ReadViewEntries&Start=1&Count=100 And this works perfectly. The problem arises when I am trying to get message contents (0A1DA5EEB7B65277C12576F50055D811 is an example message unique Id): https://your.server.domain/mail_db/mailbox.nsf/($Inbox)/0A1DA5EEB7B65277C12576F50055D811/?OpenDocument Such request in IE shows frameset with data hard to parse, in less common browsers like Opera it informs about unsupported browser. Ideally if it is possible to fetch notes message contents and all attachments by requesting it in the url, has anybody some information what request would it be? Link to Lotus web calls reference would be even more beneficial.

• ASP.NET MVC: Is it good to access HttpContext in a controller?

  - by Zach

  I've been working with ASP.NET(WebForm) for a while, but new to ASP.NET MVC. From many articles I've read, in most cases the reason that the controllers are hard to test is because they are accessing the runtime components: HttpContext (including Request, Response ...). Accessing HttpContext in a controller seems bad. However, I must access these components somewhere, reading input from Request, sending results back via Response, and using Session to hold a few state variables. So where is the best place to access these runtime components if we don't access them in a controller? Best regards, Zach@Shine

• dump csv from sqlalchemy

  - by afilatun

  For some reason, I want to dump a table from a database (sqlite3) in the form of a csv file. I'm using a python script with elixir (based on sqlalchemy) to modify the database. I was wondering if there is any way to dump the table I use to csv. I've seen sqlalchemy serializer but it doesn't seem to be what I want. Am I doing it wrong? Should I call the sqlite3 python module after closing my sqlalchemy session to dump to a file instead? Or should I use something homemade?

• Passing hash as values in hidden_field_tag

  - by funkymunky

  I am trying to pass some filters in my params through a form like so: hidden_field_tag "filters", params[:filters] For some reason the params get changed in the next page. For example, if params[:filters] used to be... "filters"={"name_like_any"=["apple"]} [1] ...it gets changed to... "filters"="{\"name_like_any\"=[\"apple\"]}" [2] note the extra quotations and backslashes in [2] when compared to [1]. Any ideas? I'm attempting to use this with searchlogic for some filtering, but I need it to persist when I change change objects in forms. I would prefer not to have to store it in session.

• CakePHP: Why does adding 'Security' component break my app?

  - by Steve

  I have a strange problem -- of my own making -- that's cropped up, and is driving me crazy. At some point, I inadvertently destroyed a file in the app/tmp directory...I'm not sure which file. But now my app breaks when I include the "Security" component, and works just fine when it's not included. I'm thinking it might be related to the Security.salt value somehow, or possibly to the saved session info, but I don't really have a deep enough knowledge of CakePHP to figure it out. Can anyone offer any insight here?

• Nhibernate criteria query inserts an extra order by expression when using JoinType.LeftOuterJoin and Projections

This only happens when I use JoinType.LeftOuterJoin on my Projects criteria. Is this a known nhibernate bug? I'm using nhibernate 2.0.1.4000. Thanks for any insight.
