• 302 Redirect to Images in IE8 do not render image

  - by empire29

  I am helping migrate a legacy application. One of the requirements is we are able to handle requests for old images. What we have is: New site on new.com Old site on old.com Images to links (imported content) point to /imgs/cat.png however the actual image is hosted on old.com/assets/images/cat.png (for now). <img src="/imgs/cat.png"/> I setup a redirect for all png, jpg, jpeg, gif that 302's requests for new.com/imgs/(.*).(png|jpg|jpeg|gif) to http://old.com/assets/images/$1.$2 Everything works find in Chrome, Firefox and IE9 - however it was noted in IE8 the image does not render. Its possible that it has the same issue in IE7, 6 and 5.5 however I have not been able to test this. Does anyone know why this is happening and how to fix? I tried setting the contentType header on the response of the 302's to image/(png|jpg|jpeg|gif) and this did not have any impact. Any insight would be appreciated.

• Visual Studio - how to create two projects using the same sources

  - by mack369

  My solution consists of 2 executable projects and a couple dlls. Project1 is a Smart Device Project, Project2 is a Windows Forms Project. Both projects use the same libraries, the reason of that is I want to test my libraries on PC before I deploy it on the device. The problem is that the DLL project type can be Smart Device Class Library or Class Library, not both. I cannot add a reference from SD project to WF and vice versa. I was able to add reference from SD project to a dll file (generated from Class Library project) instead of the project itself, but for some reason I got the message "cannot load XXX type from YYY assembly". It doesn't depend on my code, because when I created separate project for the same sources, everything was fine. The only solution I've found is to create 2 types of projects for each library, but I don't know how to make 2 projects based on the same sources.

• generating an asp.net web application dll requirement list

  - by Oren Mazor

  I'm trying to set up a web app (32bit on ii7/win7, 32bit setting is enabled, everything is compiled to x86, using vs2008), but there's clearly some dll module loading issue happening. I've been watching procmon and fusion logs but I'm not seeing the name of the missing dll. I'm a complete newbie to asp.net (but fairly heavy experience on other platforms). I know I can call depends.exe on a binary to see what the dependancies are, but how do I do it for asp.net? specifically, is it possible to get a list of the dlls that iis7 loads for my application?

• Session is null when inherit from System.Web.UI.Page

  - by Andreas K.

  I want to extend the System.Web.UI.Page-class with some extra stuff. In the ctor I need the value of a session-variable. The problem is that the Session-object is null... public class ExtendedPage : System.Web.UI.Page { protected foo; public ExtendedPage() { this.foo = (int)HttpContext.Current.Session["foo"]; // NullReferenceException } } If I move the part with the session-object into the Load-Event everything works fine... public class ExtendedPage : System.Web.UI.Page { protected foo; public ExtendedPage() { this.Load += new EventHandler(ExtendedPage_Load); } void ExtendedPage_Load(object sender, EventArgs e) { this.foo = (int)HttpContext.Current.Session["foo"]; } } Why is the Session-object null in the first case??

• Google map blank when used with master page

  - by asp316

  I wrote a google map lookup page. Everthing worked fine until I referenced the page to use a master page. I removed the form tag from the master page as the search button on the map page is a submit button. Everything else on my page appears but the google map div appears with map navigation controls and logo but no map visuals appear. I retested with the previous, non master page version and the map appears correctly. Any thoughts on what I'm missing?

• WP7/silverlight Images does not stay within a grid/stackpanel when using the toolkit to provide gesture support

  - by gforg

  I have few buttons and below that I am displaying an image and have used the WP7/Silverlight toolkit to provide support for Gestures. Everything works fine, until i do gestures like pinch and then moving it up/down. Both these gestures work fine but they do not seem to respect the stackpanel/grid the image is present in and they go over that and on top of the buttons. Do u know how to restrict these? I see the following function when gestures are called. private void OnPinchStarted(object sender, PinchStartedGestureEventArgs e) { initialAngle = ImageScaling.Rotation; initialScale = ImageScaling.ScaleX; } private void OnPinchDelta(object sender, PinchGestureEventArgs e) { ImageScaling.Rotation = initialAngle + e.TotalAngleDelta; ImageScaling.ScaleX = ImageScaling.ScaleY = initialScale * e.DistanceRatio; } private void OnDragDelta(object sender, DragDeltaGestureEventArgs e) { ImageScaling.TranslateX += e.HorizontalChange; ImageScaling.TranslateY += e.VerticalChange; }

• How few a files does it take to load a program on Linux?

  - by BCS

  The (hypothetical for now) situation is the user of my system is going to be given a chunk of C code and needs my system to compile and run it in a chroot sandbox that is generated on the fly and I want to require the fewest files in the box as possible. I'm only willing to play with compiler and linker settings (e.g. static link everything I can expect to be able to find) and make some moderate restriction on what the code can expect use (e.g. they can't use arbitrary libs). The question is how simple can I get the sandbox. Clearly I need the executable, but what about an ELF loader and a .so for the system calls? Can I dump either of them and is there something else I'll need?

• DeleteObject method is missing in Entity Framework 4.1

  - by bobetko

  This is driving me crazy. I am getting error that object doesn't contain definition for DeleteObject. Here is my line of code that produces an error: ctx.Tanks.DeleteObject(Tank); I tried to reference another object from another edmx file that my friend has created and then everything is fine, DeleteObject exists. I don't think I miss any references in my project. And project itself contains edmx file and I used DBContext to create POCOs. Any ideas?

• Problem when reading backslash in Prolog

  - by Jerry

  I'm writing a lexer in Prolog which will be used as a part of functional language interpreter. Language spec allows expressions like for example let \x = x + 2; to occur. What I want lexer to do for such input is to "return": [tokLet, tokLambda, tokVar(x), tokEq, tokVar(x), tokPlus, tokNumber(2), tokSColon] and the problem is, that Prolog seems to ignore the \ character and "returns" the line written above except for tokLambda. One approach to solve this would be to somehow add second backslash before/after every occurrence of one in the program code (because everything works fine if I change the original input to let \\x = x + 2;) but I don't really like it. Any ideas?

• Handling user input in C

  - by Stuart

  In C, I am writing a program which is taking in user input than comparing it to see which output it should use. I am finding it problomatic and was wondering if someone could give me a hand. So far I have: while(cmd[0] != EOF){ fgets(cmd, sizeof(cmd), stdin); /** Takes in user input and stores it in cmd **/ if(cmd[0] == '\n') printf("%s> ", cwd); else if(strcmp(cmd, "ls") == 0) printf("I will list everything"); } Any ideas? Basically it is just ignoring any user input when there is some. P.S. The variable cwd is just a string.

As of now everything works fine but now I want to do 'Forgot Password' functionality. To do this I need to decrypt the password which is saved in database to find original one. How to decrypt using digest/sha1? Or does anyone know any algorithm which supports encryption & decryption as well? I am using ruby on rails so I need Ruby way to accomplish it.

• Including the functionality of a tool within another program?

  - by darren

  Hi there I would like to write an application, for my own interest, that graphically visualizes some network concepts. Basically I would like to show the output from tools like ping, traceroute and nmap. The most obvious approach seems to be to use pipes to call out to these tools from my C program, and process the information they return. However, I would like to avoid this heavy-handed approach if possible. My question is, is it possible to somehow link against these tools, or are there APIs that can be used to gain programatic access instead? If so, is this behavior available on a tool-by-tool basis only? One reason for wanting to do this is to keep everything in a single process / address space and to avoid dependance on these external tools. For example, if I wrote an iphone application, I would not be able to spawn processes to call out to the external tools themselves. Thanks for any advice or suggestions.

• @media queries - one rule overrides another?

  - by John

  I have multiple @media queries all working fine but as soon as i put in a higher max screen-width than 1024px the rules for the higher width gets applied to everything. @media screen and (max-width: 1400px) { #wrap { width: 72%; } } @media screen and (max-width: 1024px) { #slider h2 { width: 100%; } #slider img { margin: 60px 0.83333333333333% 0 2.08333333333333%; } .recent { width: 45.82%; margin: 10px 2.08333333333334% 0 1.875%; } } as you can see 1024px (and also the 800px max-width query) do not change the #wrap width and work fine. As soon as i add the 1400px max-width query it changes them to 72% for ALL sizes and does the same for any element - for instance if i set #slider img to have a margin of 40px it will show at ALL sizes even though it is only in the max-width of 1400px. Am i missing something really obvious? Been trying to work this out for the past 2 days! Thanks, John

• chatbot using twisted and wokkel

  - by dmitriy k.

  I am writing a chatbot using Twisted and wokkel and everything seems to be working except that bot periodically logs off. To temporarily fix that I set presence to available on every connection initialized. Does anyone know how to prevent going offline? (I assume if i keep sending available presence every minute or so bot wont go offline but that just seems too wasteful.) Suggestions anyone? Here is the presence code: class BotPresenceClientProtocol(PresenceClientProtocol): def connectionInitialized(self): PresenceClientProtocol.connectionInitialized(self) self.available(statuses={None: 'Here'}) def subscribeReceived(self, entity): self.subscribed(entity) self.available(statuses={None: 'Here'}) def unsubscribeReceived(self, entity): self.unsubscribed(entity) Thanks in advance.

• Declaring a prototype of type "struct" - C

  - by Jamie Keeling

  I've been racking my brains on this for a while, I'm simply trying to create a method that returns a struct as I wish to return two int's. My prototype for the method is as follows: typedef struct RollDice(); Also the method itself: typedef struct RollDice() { diceData diceRoll; diceRoll.dice1 = 0; diceRoll.dice2 = 0; return diceRoll; } The compiler shows the error: "Syntax error: ')'" for both the prototype and actual method. The struct itself: typedef struct { int dice1; int dice2; }diceData; Is it obvious where I'm going wrong? I've tried everything I can think of. Thanks

• Why browser doesnt recognize jquery when <script src="...jquery.js> is on a html page served by Goo

  - by indiehacker

  jquery.js source code is not being recognised by browser using my page.html served by Google App Engine as a http:some_request to the SDK, BUT when I load the exact same page.html into the browser directly from my local hard drive as jquery.js all works OK, it is recognized, so I know my path is OK.... I don't understand? In the header of my page.html I have the following: <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js" type="text/javascript"></script> I also tried without success in the header this: <script src="/static/jquery.js" type="text/javascript"></script> I am working along with the examples in the [Jquery tutorial][1]. I am sure there is something simple I dont understand about how .html pages served to the browser from app engine interact differently with the browser than what I normally would expect....but I frustratingly just cant get it.....everything else I have with my app engine app is working fine......would love some help so i can move forward....

• Is it possible to use Sphinx search with dynamic conditions?

  - by Fedyashev Nikita

  In my web app I need to perform 3 types of searching on items table with the following conditions: items.is_public = 1 (use title field for indexing) - a lot of results can be retrieved(cardinality is much higher than in other cases) items.category_id = {X} (use title + private_notes fields for indexing) - usually less than 100 results items.user_id = {X} (use title + private_notes fields for indexing) - usually less than 100 results I can't find a way to make Sphinx work in all these cases, but it works well in 1st case. Should I use Sphinx just for the 1st case and use plain old "slow" FULLTEXT searching in MySQL(at least because of lower cardinality in 2-3 cases)? Or is it just me and Sphinx can do pretty much everything?

• Chain dynamically created dropdowns with JQuery

  - by ricardocasares

  I'm building some kind of indefinite filters for an app, and I'm havin this problem when I clone some selects. The things is this selects are chained between them, trough the Chained Selects jQuery plugin. The problem is that every time I clone the selects, the chaining stops working, and I've tryed everything, such as .live() to make it work, but it seems I'm out of luck :D Here you have a sample of what I'm talking about, http://jsfiddle.net/7K2Eu/63/ At first, the selects chain normally, but when I clone the form, they stop working, except for the first row of selects. Thank you!!

• Overloading Controller Actions

  - by DaveDev

  Hi Guys I was a bit surprised a few minutes ago when I tried to overload an Action in one of my Controllers I had public ActionResult Get() { return PartialView(/*return all things*/); } I added public ActionResult Get(int id) { return PartialView(/*return 1 thing*/); } .... and all of a sudden neither were working I fixed the issue by making 'id' nullable and getting rid of the other two methods public ActionResult Get(int? id) { if (id.HasValue) return PartialView(/*return 1 thing*/); else return PartialView(/*return everything*/); } and it worked, but my code just got a little bit ugly! Any comments or suggestions? Do I have to live with this blemish on my Controllers? Thanks Dave

• Why is my CSS tool tip not functioning properly in Google Chrome, but fine in Firefox??

  - by JAG2007

  http://betawww.helpcurenow.org/media/press/ You'll see I have used spans within an anchor, with the span.hover-description set to display:none; by default, and on a:hover that span is set to display block and absolutely positioned to create a tool-tip effect when hovering over the name and email of the "For Immediate Release" contact names. Everything looks as desired in Firefox, but Chrome reveals my unknown blunder somewhere. Any help on what's the problem that is causing Chrome to not display like Firefox? Incidentally, Explorer shows the tool tip as expected, although I'm getting a funky bottom margin issue below the names, and Safari has the same issue as Chrome (must be a webkit rendering setting that I need to accommodate for).

• git undo alias with xargs

  - by ABach

  I have a git alias (git undo) that undoes everything in the working directory, including new files, changed files, and deleted files: !git reset --hard && git ls-files -d | xargs -0 git rm --ignore-unmatch && git clean -fq On OS X, this works great. On Linux, however, I run into the following issue: if no files have been deleted from the repository, the git ls-files -d | xargs -0 git rm --ignore-unmatch command will fail (xargs will be passed nothing). Is there a way to have xargs silently move on if it receives nothing from git ls-files?

• Quality Design for Asynchronous WCF Services Calls in a Middle-Tier and Returning Data to UI Tier

  - by Perplexed

  I have a WPF application with a group of asynchronous WCF service calls all mashed into the code behind, complete with event handlers and everything, that I have to refactor to productionize and maintain. I want to separate concerns here for maintainability and all the other good reasons to do this, but I'm not sure exactly how to achieve this. Anybody have any good ideas on how to do this, or at least some links to put me in the right direction? My thinking: Create an "infrastructure" layer and reference the services there. Move the asynchronous event handlers into this layer. When an update is called, I will bubble up my own event with my own derivation of the EventArgs class that contains the data the UI will need. I'll have a fairly coupled hooking of the UI to the infrastructure layer as it will consume events I fire off upon completion of an asynchronous data call.
