  • How to use SSRS to retrieve HTML snippets with embedded images the easy way

    - by Ram
    I have a web-app that retrieves reports from our SSRS server dynamically - we hit a URL and out pops some HTML4.0 which I stuff into a div for the user to view. I recently tried adding a report that has an embedded image (in the RDL itself) and the image doesn't make it through. What does make it through is an IMG SRC reference back to the SSRS box but we do not allow end users to hit the SSRS box directly... users query the web-app and the web-app interacts with the SSRS service. There is an option to render in MHTML (note that we typically use rs:command=RenderHTML with rs:format=HTML4.0) - the blob returned appears to be valid MIME but does not seem friendly for stuffing into a DIV... am I missing something obvious? My next step is to parse the MIME, swizzle the references and stuff the whole thing back into the page but I feel like this is the hardway. What is the easy way to retrieve HTML snippet reports out of SSRS with embedded images?

  • Snow Leopard 10.6.3 Freezes Frequently

    - by Abhishek
    Snow Leopard 10.6.3 on my Macbook Pro freezes quite frequently now. It freezes for few seconds and then works fine. During that time trackpad does not work and keyboard works partially (missing keystrokes while I type). Initially it was once or twice in a day but now it has become quite frequent. Is somebody else facing similar issue?

  • Looking for something to monitor an Internet Shared Connection in Windows XP

    - by thenewbie
    If someone knows a software with these features: Works from the tray area Very lightweight Works also in Windows XP (preferably workstation, nothing serverish required) Can show a bandwidth usage graph, where I can easily see each PC's usage I can inspect a computer's connections, find out the ports and applications that are using them (eg, all bandwidth is consumed by PC #3, that's running uTorrent.exe from port 33003) ...I'd happily check it out. I'm only sharing my connection with (at most) 4 computers, I'd prefer not having to add hardware or reinstall my system. Thanks in advance!

  • RSpec: in-depth differences between before(:all) and before(:each)

    - by gmile
    Ok, so I've ran into a very strange issue, directly connected with before blocks. I'm doing a integration testing via Watir and RSpec. For a simple test to check if user can perform a login I'm creating a 'user' record in the db by means of factory_girl. So I put the following code: before(:each) do @user = Factory(:user) end if "should perform a login" do # do stuff end In do stuff I call a browser and see how the user tries to login. Unfortunately, somehow he cannot do that — "Username isn't valid". After some investigation I discovered that if I put the code for creating user in before(:all) block, everything magically works. How's that? What's the difference between :all and :each in this context? Also, If I put the code for creating user actually in the test body, it still doesn't work (i.e. user somehow isn't added to the DB or something).

How can I modify this to first run OfflineFactsheetBase's ExtractPageData() and then GenericOfflineCommentary's?

  • Preparing for a C#, ASP.NET, JavaScript interview

    - by halivingston
    I have an interview I'm prepping for, I've written A LOT of code, specifically in C# and ASP.NET. I've written fair amounts of JavaScript, but no OO stuff in it. So I'm definately going to brush up on that. I remember for a previous job interview, I was asked Java questions, like not super intricate, but detailed stuff. Now I'm looking for a book maybe that I can read through in a day (or two) and known all the crannies of C#, ASP.NET and JavaScript. Different books obviously I'll be honest, for the Java interview, I actually read The J2EE certification book, and it helped A LOT!

  • How to keep a .NET console app running?

    - by intoorbit
    Consider a Console application that starts up some services in a separate thread. All it needs to do is wait for the user to press Ctrl+C to shut it down. Which of the following is the better way to do this? static ManualResetEvent _quitEvent = new ManualResetEvent(false); static void Main() { Console.CancelKeyPress += delegate { _quitEvent.Set(); }; // kick off asynchronous stuff _quitEvent.WaitOne(); // cleanup/shutdown and quit } Or this, using Thread.Sleep(1): static bool _quitFlag = false; static void Main() { Console.CancelKeyPress += delegate { _quitFlag = true; }; // kick off asynchronous stuff while (!_quitFlag) { Thread.Sleep(1); } // cleanup/shutdown and quit }

  • applying a var to an if statement jquery

    - by Dirty Bird Design
    Need to apply a var to a statement if its conditions are met, this syntax isn't throwing errors but its not working. <script type="text/javascript"> $(document).ready(function(){ var action_is_post = false; //stuff here $(this).ready(function () { if ($("#stepDesc0").is(".current")) { action_is_post = true; } }); //stuff here </script> should I use something other than .ready? Do I even need the $(this).ready(function ()... part? I need it to apply the var when #stepDesc0 has the class current.

  • Resizing iframe height using javascript issue

    - by Camran
    I have an iframe which content is a php-file, and that php-file displays some mysql records. The more records, the larger the iframe height should get, otherwise it wont show all of the information in the iframe. Here is a code I have for dynamically setting the iframe height, from the iframes content (the php file): var x = document.body.scrollHeight; x = x + 20 + 'px'; window.parent.document.getElementById("iframe001").style.height=x; iframe001 is the iframe I am referring to above. I am adding 20px of height extra because of borders etc... Now, sometimes this resizing works, sometimes it doesn't. Does anybody know why it works sometimes. If I alert the 'x' variable, it shows different values sometimes, but most times it works. Any other ways you know of setting the iframes height from the content of the iframe? Thanks

  • Weird behaviour with optparse and bash tab completion

    - by PulpFiction
    Hi I am building a script for users new to Linux, so please understand why I am asking this :) My script runs like this: python script.py -f filename.txt I am using the optparse module for this. However, I noticed the following when doing tab completion. The tab completion works when I do: python script.py <tab completion> # Tab completion works normally as expected But it does not work when I do it like this: python script.py -f <tab completion> # No type of tab completion works here. I really don't want my users typing the name of the input file. Tab completion is a must. How can I get it working or what am I doing wrong here?

  • Passing arguments to Shared Function - C

    - by SpyrosR
    I have used dlopen to load an object and dlsym to get a function pointer to a shared object function. Everything works fine. I have tested it calling then the shared function which (for now) only prints and it works-prints fine in the main program calling it. Now I want to pass two arguments to this function. An int and a char * .Can anyone help me understand how can I pass arguments to a shared function? I have searched in the web but I cannot understand how it works.

  • What are parts of a PHP function named?

    - by MikeG
    I am having trouble figuring out a problem and it is because I don't know the correct terms to be searching for. Could someone please name all the parts of a PHP function and if I'm missing something please add it. function my_function( non_variable $variable_one, $variable_two = "", $variable_three ) { /* inside stuff (Statement?) */ } The answer I'm looking for would look something like this function: declaration my_function: name non_variable: Please Answer $variable_one: variable filled with non_variable The one I really need to know about are non_variable and $variable_one, Thanks! EDIT: more detail about the function function my_function(custom_name $company) { $website = $company->company_website; /* Additional stuff */ }

  • How to learn about Make, compiling

    - by drozzy
    Why is Make utility for installing stuff on Linux so complicated? I mean it is really hard to know exactly where stuff goes on the machine. /etc/local? usr local? non-local? It just seems like really chaotic directory structure. Is there some "guide" on how this works? I mean as a new programmer, coming into the world of compiling things - where does on start? Thanks.

  • Javascript clone form?

    - by user202987
    I need to copy a form information with all types of elements and send it with AJAX. Tried these: 1. cloneNode on the form. - Doesn't work with IE, only copies text stuff properly. cloneNode on each element. Doesn't work with IE, only copies text stuff properly. Making new textareas for each element, and copying the value in. Doesn't work for textareas in IE, formatting is lost. I imagine a combination of those 3 would work for IE and FF but is there any decent solution to this? Shortness of code is a priority.

  • Javascript function programming — receiving elaborate parameters

    - by Barney
    I'm writing a Javascript function that would manipulate an array written on-the-fly and sent as a parameter. The function is written as follows: function returnJourney(animation,clean){ var properties = {}; // loads of other inane stuff for(i in animation[0]) properties[animation[0][i]] = animation[0].i; // heaps more inane stuff } The animation in question is a set of parameters for a jQuery animation. Typically it takes the format of ({key:value,key:value},speedAsInteger,modifierAsString). So to kick off initial debugging I call it with: returnJouney(({'foo':'bar'},3000),1); And straight off the bat things are way off. As far as I see it this would have returnJourney acknowledge clean === 1, and animation being an array with an object as its first child and the number 3000 as its second. Firebug tells me animation evaluates as the number 3000. What am I doing wrong?

  • Windows update on netbook requires CD (hint, there's no CD drive)

    - by bwooceli
    An "Important" update for Microsoft Works (via Windows Update) on a Dell netbook gets about halfway through and then pops up with the super-awesome "Please insert Microsoft Works 9.0 disc" message. Of course, the netbook has no CD rom drive, there is no handy folder (that i can find) containing "Works9.msi", and I have no Works9 disc. It wouldn't be so bad, except the update keeps coming up everytime WU runs. Any suggestions?

  • How can I map a String to a function in Java?

    - by Bears will eat you
    Currently, I have a bunch of Java classes that implement a Processor interface, meaning they all have a processRequest(String key) method. The idea is that each class has a few (say, <10) member Strings, and each of those maps to a method in that class via the processRequest method, like so: class FooProcessor implements Processor { String key1 = "abc"; String key2 = "def"; String key3 = "ghi"; // and so on... String processRequest(String key) { String toReturn = null; if (key1.equals(key)) toReturn = method1(); else if (key2.equals(key)) toReturn = method2(); else if (key3.equals(key)) toReturn = method3(); // and so on... return toReturn; } String method1() { // do stuff } String method2() { // do other stuff } String method3() { // do other other stuff } // and so on... } You get the idea. This was working fine for me, but now I need a runtime-accessible mapping from key to function; not every function actually returns a String (some return void) and I need to dynamically access the return type (using reflection) of each function in each class that there's a key for. I already have a manager that knows about all the keys, but not the mapping from key to function. My first instinct was to replace this mapping using if-else statements with a Map<String, Function>, like I could do in Javascript. But, Java doesn't support first-class functions so I'm out of luck there. I could probably dig up a third-party library that lets me work with first-class functions, but I haven't seen any yet, and I doubt that I need an entire new library. I also thought of putting these String keys into an array and using reflection to invoke the methods by name, but I see two downsides to this method: My keys would have to be named the same as the method - or be named in a particular, consistent way so that it's easy to map them to the method name. This seems WAY slower than the if-else statements I have right now. Efficiency is something of a concern because these methods will tend to get called pretty frequently, and I want to minimize unnecessary overhead. TL; DR: I'm looking for a clean, minimal-overhead way to map a String to some sort of a Function object that I can invoke and call (something like) getReturnType() on. I don't especially mind using a 3rd-party library if it really fits my needs. I also don't mind using reflection, though I would strongly prefer to avoid using reflection every single time I do a method lookup - maybe using some caching strategy that combines the Map with reflection. Thoughts on a good way to get what I want? Cheers!

  • Printing Work Items in TFS

    - by user351671
    Hi, I am looking for a fancy way the print individual work items in TFS. OK ... maybe not the work item directly but I need to produce printable forms based on data on a work item. And by fancy I mean: header, footer, formatting, tables maybe ... stuff like that. No, I am not trying to print a list of work items, read carefully, I need an output based on a single work item. For those who are wondering "Why on earth do you need that?" I should say: We are keeping everything on TFS around here. (For now only software development stuff, but I am thinking bigger...) Sometimes somethings need to be on hard copy, to be signed for instance, and that is why I need printable forms.

  • C++ Generic List Assignment

    - by S73417H
    I've clearly been stuck in Java land for too long... Is it possible to do the C++ equivalent of the following Java code: // Method List<Bar> getBars() { return new LinkedList<Bar>(); } // Assignment statement. List<Foo> stuff = getBars(); Where Foo is a sub-class of Bar. So in C++.... std::list<Bar> & getBars() { std::list<Bar> bars; return bars; } std::list<Foo> stuff = getBars(); Hope that makes sense....
