  • Referencing both an old version and new version of the same DLL (VB.Net)

    - by ckittel
    Consider the following situation: WidgetCompany produced a .NET DLL in 2006 called Widget.dll, version 1.0. I consumed this Widget.dll file throughout my VB.Net application. Over time, WidgetCompany has been updating Widget.dll, I never bothered to keep up, continuing to ship version 1.0 of Widget.dll with my software. It's now 2010, my project is now a VB.Net 3.5 application and WidgetCompany has come out with Widget.dll version 3.0. It looks and functions almost identical to Widget.dll version 1.0, using all the same namespaces and type names from before. However, Widget.dll version 3.0 has many run-time breaking changes since 1.0 and I cannot simply cut over to the new version; however, I don't want to continue developing against the 1.0 version and therefore keep digging myself deeper in the hole. What I want to do is do all new development in my project with Widget.dll version 3.0, whilst keeping Widget.dll version 1.0 around until I find time to convert all of my 1.0 consumption to the newer 3.0 code. Now, for starters, I obviously cannot simply reference both Widget.dll (Ver 1.0) and Widget.dll (Ver 3.0) in Visual Studio. Doing so gives me the following message: "A reference to 'Widget.dll' could not be added. A reference to the component 'Widget' already exists in the project." To work around that, I can simply rename version 3.0 Widget.dll to Widget.3.dll. But this is where I'm stuck. Any attempts to reference types found in "the dll" leads to ambiguity and the compiler obviously doesn't have any clue as to what I really want in this or that case. Is there something I can do that gives a DLL a new "root" Namespace or something? For example, if I could say "Widget.dll has a new root namespace of Legacy" then I could update existing code to reference the types found in Legacy.<RootNamespace> namespace while all new code could simply reference types from the <RootNamespace> namespace. Pipe dream or reality? Are there other solutions to situations this (besides "don't get in this situation in the first place")?

  • Ignoring build number when referencing dll

    - by brickner
    I have one solution with a .NET 4.0 project (C#) that produces a delayed signed dll, that I dotfuscate and sign. EDIT: This is how I version the dll: [assembly: AssemblyVersion("0.7.0.*")] [assembly: AssemblyFileVersion("0.7.0.0")] I have another solution with a .NET 4.0 project (C++/CLI) that references the signed dll and produces a signed dll (actually, delayed signed and signed in a post build because of a flaw in the C++ build system). The problem is that the reference to the dll contains a specific version number, which includes even the build number (I want to have a build number). Every time I build the referenced dll, I have to change the project settings file (.vcxproj) so it reference the new version dll. Since I work with source control, this is very inconvenient (different computers might have different build numbers since each computer build its own referenced dll - the referenced dll is not in the source control). If I don't change the reference, I get a warning: warning MSB3245: Could not resolve this reference. Could not locate the assembly... And many errors like this: error C3083: 'Foo': the symbol to the left of a '::' must be a type These are resolved once I change the reference. How do I make the reference ignore the build number or even the entire version number?

  • Recover from inadvertent skip during rebase

    - by Benjol
    I just tried to rebase a very old branch with a minor modification onto my master. There was a problem with merging just one of the three files involved, so I did an unthinking --skip, thinking that it would just skip that file, but as it happened, it seems to have skipped all my changes, and rolled forwards. So now the rebase is finished, and my changes seem to have disappeared. I've seen the question about undoing rebase, but it's all greek to me, I see the reflog, but I don't know which commit the branch was attached to before the rebase. In any case, I don't really need to undo the rebase, I just want to be able to recover the changes in the two files. Is there anyway to do this properly (failing this, I'll just have to restore yesterday's backup of my repository and pick the bits out by hand).

  • Javascript AJAX function returns undefined instead of true / false

    - by Josh K
    I have a function that issues an AJAX call (via jQuery). In the complete section I have a function that says: complete: function(XMLHttpRequest, textStatus) { if(textStatus == "success") { return(true); } else { return(false); } } However, if I call this like so: if(callajax()) { // Do something } else { // Something else } The first is never called. If I put an alert(textStatus) in the complete function I get true, but not before that function returns undefined.

  • Grouping DLL's for use in Executable

    - by Peter Turner
    Is there a way to group a bunch of DLL's and still use them at run time (not zipped up). Sorry this question sounds terse and stupid, but I'm not sure what more to ask. I'll explain the situation though: We've had two standalone Windows Applications and now one of our Applications has swelled to such ungainly proportions that the other application cannot run outside of the scope of the first app. We want to maintain some of the encapsulation we had while letting the smaller program in on some of the bigger program's features. There is no problem in running the application, other than we don't want to send out all the 20-30 DLL's that the smaller project has.

  • Sys. engineer has decided to dynamically transform all XSLs into DLLs on website build process. DLL

    - by John Sullivan
    Hello, OS: Win XP. Here is my situation. I have a browser based application. It is "wrapped" in a Visual Basic application. Our "Systems Engineer Senior" has decided to spawn DLL files from all of our XSL pages (many of which have duplicate names) upon building a new instance of the website and have the active server pages (ASPX) use the DLL instead. This has created a "known issue" in which ~200 DLL naming conflicts occur and, thus, half of our application is broken. I think a solution to this problem is that, thankfully, we're generating the names of the DLLs and linking them up with our application dynamically. Therefore we can do something kludgy like generate a hash and append it to the end of the DLL file name when we build our website, then always reference the DLL that had some kind of random string / hash appended to its name. Aside from outright renaming the DLLs, is there another way to have multiple DLLs with the same name register for one application? I think the answer is "No, only between different applications using a special technique." Please confirm. Another question I have on my mind is whether this whole idea is a good practice -- converting our XSL pages (which we use in mass -- every time a response from our web app occurs) into DLL functions that call a "function" to do what the XSL page did via an active server page (ASPX), when we were before just sending an XML response to an XSL page via aspx.

  • Recovery from hell - undeleting partition overwritten by Xubuntu 12.10 installer?

    - by DaimyoKirby
    This is turning into a nightmare - following my initial recovery of my two partitions, I went to install Xubuntu 12.10 (again). At this time I had two partitions - one of ~39 GB had Zorin OS 6 installed on it, and another of ~33 GB had nothing installed, just a few files in it that I had manually backed up (moved) there. When I got to the partitioning step, I chose "Replace Zorin OS 6 with Xubuntu 12.10", along with LVM, naturally thinking that the installer wouldn't touch the second partition, since Zorin wasn't installed on it. I was dead wrong. Upon booting my newly installed Xubuntu 12.10, I found in gparted that there were only two partitions - ~255MB, which appears to have the boot stuff in it (it's flagged boot in gparted), and another of ~74 GB. Question: Is there any way to salvage my old files on the non-Zorin ext3 partition? I'm really upset I made such a dumb move (again...), and any and all help is appreciated very, very much!

  • Downloading anything is hell and arduous without an application. Care to help out an Ubunt-noob?

    - by FilthyCasual
    Torrent from the Pirate Bay even though I have Tixati installed and working? Asks for an application which I don't have (apturl or something similar?) Trying to get the latest AMD Radeon drivers automatically installed? the main file downloads...but just shows up in a window full of files but idk where to drag them. And PlayOnLinux my one hope for gaming since Steam is buggin out without proper drivers? Can't figure out where to "mount" the DVD version it asks for. I'm so lost. I dove head first into the Linux thing thinking it was wildly superior, and maybe it is, but dang if the simplest things aren't hard to do. Any help appreciated. I've been reading guides and manuals but what I need is human experience most of all.

  • PHP Thumbnail image generator works, but consistently awaits 90% of its loadtime! Why?

    - by Sam
    Hi folks, This is the follow-up question from this general page load speed question. This question which will focus only, entirely and specifically on the thumbnail generator PHP code with the question: What's causing the 97% delays on these tiny thumbnails? Measuring only 3 ~ 5 kb each, this is strange indeed! Even after 7 orso bounty-rounds and 100 upvotes, the images are still doing nothing for over 97% of the time. It works allright, but it could be so much faster! ZAM, my pet robot, was so annoyed by not knowing why, he just pulled out some cords! Silly metal box... (I have asked permission from the original author, to put temporarily segments of the code online that I think could be the problem, after which I will remove all code, except the several lines that were the direct cause of this issue here to match the answer. This will be the free opportunity to perfect/speedup his otherwise already to my opinion vert versatile and userfriendly thumbnail generator.)

  • Linux depends hell when installing a small mp3 player...

    - by smwikipedia
    I try to install a small audio player named "Audacious" with the following command: sudo apt-get install audacious and it tells me that it depends audacious-plugins, so I try to install the audacious-plugins, one thing leads to another, there're numerous depends and it is just impossible to install all of them manually... Is it even possible to install a software on ubuntu linux? Is there a way to auto install all the depends? (I have never seen such a stupid software manager.) Many thanks.

  • why the hell does x,y = zip(*zip(a,b)) work in Python?

    - by Mike Dewar
    OK I love Python's zip() function. Use it all the time, it's brilliant. Every now and again I want to do the opposite of zip(), think "I used to know how to do that", then google python unzip, then remember that one uses this magical * to unzip a zipped list of tuples. Like this: x = [1,2,3] y = [4,5,6] zipped = zip(x,y) unzipped_x, unzipped_y = zip(*zipped) unzipped_x Out[30]: (1, 2, 3) unzipped_y Out[31]: (4, 5, 6) What on earth is going on? What is that magical asterisk doing? Where else can it be applied and what other amazing awesome things in Python are so mysterious and hard to google?

  • How the hell do you get clients to use your bug tracking system?

    - by louism
    on larger projects i use a simple bug tracking system thats designed to be used by clients i have a lot of trouble convincing clients to use it (they send bug reports via email) does anyone have any strategies they can suggested? also, i have been playing around with a theory as to why this is the case; it goes like this: asking a client to log a bug is like taking your car to a mechanic for a service, and the mechanic hands you the engine oil and says "here, pop that in". basically, the client has paid you to do the work, logging a bug sounds too much like work, so they want you to do it thoughts? -- LM

  • Drawing an image in Java, slow as hell on a netbook.

    - by Norswap
    In follow-up to my previous questions (especially this one : http://stackoverflow.com/questions/2684123/java-volatileimage-slower-than-bufferedimage), i have noticed that simply drawing an Image (it doesn't matter if it's buffered or volatile, since the computer has no accelerated memory*, and tests shows it's doesn't change anything), tends to be very long. (*) System.out.println(GraphicsEnvironment.getLocalGraphicsEnvironment() .getDefaultScreenDevice().getAvailableAcceleratedMemory()); --> 0 How long ? For a 500x400 image, about 0.04 seconds. This is only drawing the image on the backbuffer (obtained via buffer strategy). Now considering that world of warcraft runs on that netbook (tough it is quite laggy) and that online java games seems to have no problem whatsoever, this is quite thought provoking. I'm quite certain I didn't miss something obvious, I've searched extensively the web, but nothing will do. So do any of you java whiz have an idea of what obscure problem might be causing this (or maybe it is normal, tough I doubt it) ? PS : As I'm writing this I realized this might be cause by my Linux installation (archlinux) tough I have the correct Intel driver. But my computer normally has "Integrated Intel Graphics Media Accelerator 950", which would mean it should have accelerated video memory somehow. Any ideas about this side of things ?

  • What is the right way to do this HTML: header with icon linked

    - by Hell Awaits
    I know how to make these examples look and behave the same. But I would like to know which is the right way to build a HTML structure. <a><img><h1></h1></a> - looks wrong because an inline element is inside of a block element <a><img></a><h1><a></a></h1> - the same a-element is defined twice. Also I'm not sure about markup inside headers Any other solutions ?

  • Python: User-Defined Exception That Proves The Rule

    - by bandana
    Python documentations states: Exceptions should typically be derived from the Exception class, either directly or indirectly. the word 'typically' leaves me in an ambiguous state. consider the code: class good(Exception): pass class bad(object): pass Heaven = good() Hell = bad() >>> raise Heaven Traceback (most recent call last): File "<pyshell#163>", line 1, in <module> raise Heaven good >>> raise Hell Traceback (most recent call last): File "<pyshell#171>", line 1, in <module> raise Hell TypeError: exceptions must be classes or instances, not bad so when reading the python docs, should i change 'typically' with ''? what if i have a class hierarchy that has nothing to do with the Exception class, and i want to 'raise' objects belonging to the hierarchy? i can always raise an exception with an argument: raise Exception, Hell This seems slightly awkward to me What's so special about the Exception class, that only its family members can be raised?
