Map the physical file path in asp.net mvc

- by rmassart

Hi, I am trying to read an XSLT file from disk in my ASP.Net MVC controller. What I am doing is the following: string filepath = HttpContext.Request.PhysicalApplicationPath; filepath += "/Content/Xsl/pubmed.xslt"; string xsl = System.IO.File.ReadAllText(filepath); However, half way down this thread on forums.asp.net there is the following quote HttpContext.Current is evil and if you use it anywhere in your mvc app you are doing something wrong because you do not need it. Whilst I am not using "Current", I am wondering what is the best way to determine the absolute physical path of a file in MVC? For some reason (I don't know why!) HttpContext doesn't feel right for me. Is there a better (or recommended/best practice) way of reading files from disk in ASP.Net MVC? Thanks for your help, Robin

How do I get a linq to sql group by query into the asp.net mvc view?

- by Brad Wetli

Sorry for the newbie question, but I have the following query that groups parking spaces by their garage, but I can't figure out how to iterate the data in the view. I guess I should strongly type the view but am a newbie and having lots of problems figuring this out. Any help would be appreciated. Public Function FindAllSpaces() Implements ISpaceRepository.FindAllSpaces Dim query = _ From s In db.spaces _ Order By s.name Ascending _ Group By s.garageid Into spaces = Group _ Order By garageid Ascending Return query End Function The controller is taking the query object as is and putting it into the viewdata.model and as stated the view is not currently strongly typed as I haven't been able to figure out how to do this. I have run the query successfully in linqpad.

Grails Remote Function and Ajax

- by WaZ

I am trying to list addresses and onChange event I send the address ID and return a list of users. <g:select name="AddressID" from="${address}" optionKey="id" optionValue="address" onchange="${ remoteFunction(action:'testMe', params:'\'id=\' + this.value' ,update:'show' )}"> </g:select> I call this div "show". <div id="show"> <g:each in="${users}" status="i" var="C"> <h3>${C}</h3> </g:each> </div> However, when I click the item on the list box I get the following error: description The requested resource (/MyTest/WEB-INF/grails-app/views/test/testMe.jsp) is not available. My understanding of an update attribute inside a remoteFunction is that it is the name of the div which gets refreshed after the remoteFunction call is compeleted. Thanks.

Using installshield to replace a same-versioned DLL in the GAC

- by Kevin

We recently put out an update of one of our apps with a "test" DLL from a third party. The third party does not update their assembly versions on the dll's, only the file versions, so multiple apps can reference different "versions" of it. However, the GAC still allows us to keep the newest version, because it also checks the file version which is always updated. What happened is we were not ready to release this DLL, but it got out there on some customer machines. I would like to put our current live version back out there, but it has an older file version (and the same assembly version) as the test DLL. We have multiple apps referencing this DLL, so I can't simply delete it and drop in the new one. Is there a way to replace the DLL in the GAC? I'm using installshield 2009. Perhaps some sort of custom action upon install?

Swapping UIImages causing 'unrecognized selector sent to instance' ?

- by user158103

Error: [__NSCFDate drawAtPoint:]: unrecognized selector sent to instance 0xd251e0 Termininating app due to uncaught exception 'NSInvalidArgumentException' Scenario: for the most part this works. But I notice this error, even on the simulator, when I swapping UIImages, slowly, but consistently. For example, I have a retained reference to a UIImage that im drawing. By the click of a picker control I am changing the face image (this occurs in another view-controller). I can consistently recreate this error by continuously changing the faces. It usually crashes at about the 4th swap or more. My theory: It's not loading the image, therefore the image reference is nil. I know ive read a bit about UIImage being cached, so I wouldnt think im running out of memory. Any ideas? Thanks!

Authlogic auto login fails on registration with STI User model

- by Wei Gan

Authlogin by default is supposed to auto login when the user's persistence token changes. It seems to fail in my Rails app. I set up the following single table inheritance user model hierarchy: class BaseUser < ActiveRecord::Base end class User < BaseUser acts_as_authentic end create_table "base_users", :force => true do |t| t.string "email" t.string "crypted_password" t.string "persistence_token" t.string "first_name" t.string "last_name" t.datetime "created_at" t.datetime "updated_at" t.string "type" end To get auto login to work, I need to explicitly log users in in my UsersController: def create @user = User.new(params[:user]) if @user.save UserSession.create(@user) # EXPLICITLY LOG USER IN BY CREATING SESSION flash[:notice] = "Welcome to Askapade!" redirect_to_target_or_default root_url else render :action => :new end end I was wondering if it's anything to do with STI, or that the table is named "base_users" and not "users". I set it up before without STI and it worked so I'm wondering why once I put in place this hierarchy, it fails. Thanks!

Fake "user initiated" <audio> tag on iPad

- by Alex Ford

I know that Apple's docs say that an mp3 within an <audio tag on iPhone OS can't be played without user intervention (they cite bandwidth concerns, totally reasonable). However, has anyone succeeded in faking a user action to play the audio? Perhaps faking events to off screen native audio controls with JavaScript? I'm using jPlayer right now which works great on desktop Safari, but is silent on my iPad. I'm prototyping a touch interface using WebKit on the iPad, and audio is an integral part of the experience, so yes, I do have a good reason to want to override this convention. I'd appreciate any help. Thanks.

MOSS Collect Data from user custom email

- by nav

Hi, I am trying to send out a custom email, after the Collect Data from user step in my primary workflow which starts when an item in list X is created. I have created a secondary workflow to start when a new Task item is created (this is created by the Collect Data from user action in the primary workflow). But I am having problem how I retrieve the information on the list X. I know the ID of the referenced item in List X is stored in a URL within the "Link" column in the Tasks lists. But can't see any string manipulation function that will grab this ID so I can use it to link back to relevant item in List X. Is there an easier way to do this? Many Thanks, Nav

ASP.NET binding object to Request in asp.net mvc

- by Alxandr

I've created a object that I'd like to have accessible from wherever the request-object is accessible, and to "die" with the request, more or less like how you always in a mvc-application has access to the RouteData-collection. Especially it's important that I have access to this object in the execution of action-filters. And also there need to be created a new object of my class whenever a new request is made to the page (the object needs to be request-safe, ie. only one request modifies that one object). Any thoughts about how to achieve this?

Decoding equivalent assembly code of C code...

- by puffadder

Hi All, Wanting to see the output of the compiler (in assembly) for some C code, I wrote a simple program in C and generated its assembly file using gcc. The code is this: #include <stdio.h> int main() { int i = 0; if ( i == 0 ) { printf("testing\n"); } return 0; } The generated assembly for it is here (only the main function): _main: pushl %ebpz movl %esp, %ebp subl $24, %esp andl $-16, %esp movl $0, %eax addl $15, %eax addl $15, %eax shrl $4, %eax sall $4, %eax movl %eax, -8(%ebp) movl -8(%ebp), %eax call __alloca call ___main movl $0, -4(%ebp) cmpl $0, -4(%ebp) jne L2 movl $LC0, (%esp) call _printf L2: movl $0, %eax leave ret I am at an absolute loss to correlate the C code and assembly code. All that the code has to do is store 0 in a register and compare it with a constant 0 and take suitable action. But what is going on in the assembly ? Thanks in advance.

Web Setup Project - Getting the Current Machine Name

- by Shane Kenney

I've got a web setup project with a custom screen in it that asks for a machine name. Is there anyway to prepopulate this field with the current machines name? For the case that I need it for just including "Localhost" does not meet my requirements. "Environment.MachineName" will return the machine name within a code block which would be fine if I was needing it in a custom action. But it seems custom actions don't excecute until after you go through the installation wizard... So I cant actually use it. Anyway let me know what you think.

How to add uitoolbar to uitableviewcontroller?

I have an UITableViewController which I would like to add UIToolbar to with one button. In the - (void)viewDidLoad; method of UITableViewController I have: - (void)viewDidLoad { [super viewDidLoad]; UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(pressButton1:)]; self.navigationItem.title = @"Some title"; self.navigationItem.leftBarButtonItem = button; } Unfortunately I don't see the toolbar when I run my app. Any hints? Should I do something more?

How can I create a button with a UIActivityIndicator in my navigation bar with the same style as nor

- by Jarin Udom

All of the examples I've seen on here and other sites involved creating a UIActivityIndicatorView and loading it with something like: self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithCustomView:myActivityIndicatorView target:nil action:nil] autorelease]; However, that just creates a plain activity indicator in the navigation bar. What I want to do is have a button that looks just like the normal UIBarButtonSystemItem buttons but with an activity indicator instead of one of the default images. I've tried doing initWithImage and initWithTitle with nil images or titles and then adding the activity indicator as a subview, but that doesn't work. Any ideas?

Artificial Intelligence in online game using Google App Engine

- by Hortinstein

I am currently in the planning stages of a game for google app engine, but cannot wrap my head around how I am going to handle AI. I intend to have persistant NPCs that will move about the map, but short of writing a program that generates the same XML requests I use to control player actions, than run it on another server I am stuck on how to do it. I have looked at the Task Queue feature, but due to long running processes not being an option on the App engine, I am a little stuck. I intend to run multiple server instances with 200+ persistant NPC entities that I will need to update. Most action is slowly roaming around based on player movements/concentrations, and attacking close range players...(you can probably guess the type of game im developing)

How to delete table rows programmatically?

- by Donal O'Danachair

I have a table which I am manipulating with a tableViewController (no nib, and the controller is creating the table behind the scenes) I'm trying to delete a row from the table based on its row number; I can delete it from the array I use to create the cell in cellForRowAtIndexPath, but I get a strange error if I try to do the following, which is the same code as in tableView:commitEditingStyle:forRowAtIndexPath: where it works fine NSIndexPath *indexPath = [NSIndexPath indexPathForRow:i+1 inSection:1] [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; It gives an error -[_WebSafeForwarder forwardInvocation:] and then jumps out of the method but does not crash the app Can anyone help?

Need help understanding _set_security_error_handler()

- by Emil D

So , I've been reading this article: http://msdn.microsoft.com/en-us/library/aa290051%28VS.71%29.aspx And I would like to define my custom handler.However, I'm not sure I understand the mechanics well.What happens after a call is made to the user-defined function ( e.g. the argument of _set_security_error_handler() ) ? Does the program still terminate afterward ? If that is the case, is it possible to terminate only the current thread(assuming that it is not the main thread of the application).AFAIK, each thread has its own stack , so if the stack of a thread gets corrupted, the rest of the application shouldn't be affected. Finally, if it is indeed possible to only terminate the current thread of execution, what potential problems could such an action cause? I'm trying to do all this inside an unmanaged C++ dll that I would like to use in my C# code.

Move entire line up and down in Vim

- by guy.incognito

In Notepad++, I can use ctrl + shift + up/down to move the current line up and down. Is there a similar command to this in Vim? I have looked through endless guides, but have found nothing. If there isn't, how could I bind the action to that key combination? Edit: Mykola's answer works for all lines, apart from those at the beginning and end of the buffer. Moving the first line up or the bottom line down deletes the line, and when moving the bottom line up it jumps two spaces initially, like a pawn! Can anyone offer any refinements?

How to programatically record the start and end of an MVC FileResult for logging of incomplete downl

- by Richard

Hi, I have been investigating how My ASP.NET MVC application can log unsuccessful / incomplete downloads. I have a controller handling the file requests which currently returns a FileResult. What I need to record is the IPAddress, filename and when the download started, then the same data and when it completed. I have looked at intercepting the request start and end with an HttpModule and also IIS7 failed request tracing but am not sure which route would be best and have this feeling that maybe I am missing an obvious answer to the problem. Does anyone have any suggestions or know of any alternatives as this seems like something many people would want to know from their web server? Thanks for your help

SQLBulkCopy used in conjunction with Transaction and firing an event each time a batch is copied

- by Hans Rudel

Im currently uploading data to MS SQL server via SQLBulkCopy and Transactions. I would like to be able to raise an event after each batch has been uploaded (I have already tried SQLRowsCopied event and it doesnt work, see quote below) MSDN quote: No action, such as transaction activity, is supported in the connection during the execution of the bulk copy operation, and it is recommended that you not use the same connection used during the SqlRowsCopied event. However, you can open a different connection. http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlbulkcopy.sqlrowscopied(v=vs.80).aspx So i basically cant have my cake and eat it :( Does anyone know a solution around this as i would like to fire an event after each batch has been uploaded. Thanks for your help.

How do I center a DIV in the exact center of a page using jQuery?

- by sadmicrowave

I need to center a DIV in the exact center of a page using jquery. My CSS style for the DIV is as follows: #page-content #center-box{ position:absolute; width:400px; height:500px; background:#C0C0C0; border:1px solid #000; } and my jQuery for centering is as follows: windowheight = $(window).height(); windowwidth = $(window).width(); pagecenterW = windowwidth/2; pagecenterH = windowheight/2; $("div#page-content div#center-box") .css({top: pagecenterH-250 + 'px', left: pagecenterW-200 + 'px'}); This code does not invoke any action on my page when refreshed. What am I doing wrong?

iOS - conditional compilation (xcode)

- by sol

I have created an additional iPad target for what was originally an iphone app. From the Apple docs: "In nearly all cases, you will want to define a new view controller class to manage the iPad version of your application interface, especially if that interface is at all different from your iPhone interface. You can use conditional compilation to coordinate the creation of the different view controllers." But they don't give any example or detail on what conditional compilation is. Can anyone give an example? And where would I do this?

Twitter Bootstrap Collapsible Navbar Duplicating
