  • Is Silverlight only for eye-candy, or does it have a use in business?

    - by Cyberherbalist
    Granted that Silverlight may make eye-popping websites of great beauty, is there any justification for using it to make practical web applications that have serious business purposes? I'd like to use it (to learn it) for a new assignment I have, which is to build a web-based application that keeps track of the data interfaces used in our organization, but I'm not sure how to justify it, even to myself. Any thoughts on this? If I can't justify it then I will have to build the app using the same old tired straight ASP.NET approach I've used (it seems) a hundred times already.

  • Customers angry, fighting unknown DLL dependencies

    - by wheaties
    I'm a one man show developing a C++ Windows application for a customer. Over the past several months we've been running to the same problems with missing DLL dependencies on customer machines. Despite my best efforts something keeps going wrong and we get angry emails back. My boss and my boss's boss are angry with me and the customers aren't happy. I'm hoping you guys can help out and give suggestions/ideas on how to get the deliverables in order. Before some of the obvious: I have no test machine. That is, I can't replicate the customer environment nor attempt to install the app on a "clean" system to catch gotchas before shipping. I've tried using depends.exe to track down what versions of the DLLs my project is dependent upon. I'm shipping our code with the redistributables I've been able to find that way. After that it's an angry customer email waiting game. I'm required to use a third-party DLL which can not be registered (it's buggy as hell.) I'm not supposed to use Install Shield, any other automated installer, or write an install script. I provide written instructions on how to get the app installed (unzip, double click exe file.) I'm tired of taking heat for this stuff. What am I missing that I could be doing? What should I ask in terms of support from my employer? How should I ask for that support in a way that they'll provide it?

  • Visual C++ overrides/mock objects for unit testing?

    - by Mark
    When I'm running unit tests, I want to be able to "stub out" or create a mock object, but I'm running into DLL Hell. For example: There are two DLL libraries built: A.dll and B.dll -- Classes in A.dll have calls to classes in B.dll so when A.dll was built, the link line was using B.lib for the defintions. My test driver (Foo.exe) is testing classes in A.dll, so it links against A.lib. However, I want to "stub out" some of the calls A.dll makes to B.dll with simple versions (return basic value, no DB look up, etc). I can't build an Override.dll that just overrides the needed methods (not entire classes) and replace B.dll because Foo.exe will A) complain that B.dll is missing if I just remove it and put Override.dll in it's place or B) if I rename Override.dll to B.dll, Foo.exe complains that there are unresolved symbols because Override.dll is not a complete implementation of B.dll. Is there a way to do this? Is there a way to statically link Foo.exe with A.lib, B.lib and Override.lib such that it will work without having to completely rebuild A.lib and B.lib to remove the __delcspec(dllexport)? Is there another option?

  • How to deal with a poor team leader and a tester manager from hell? [closed]

    - by Google
    Let me begin by explaining my situation and give a little context to the situation. My company has around 15 developers but we're split up on two different areas. We have a fresh product team and the old product team. The old product team does mostly bug fixes/maintenance and a feature here and there. The fresh product had never been released and was new from the ground up. I am on the fresh product team. The team consists of three developers (myself, another developer and a senior developer). The senior is also our team leader. Our roles are as follows: Myself: building the administration client as well as build/release stuff Other dev: building the primary client Team lead: building the server In addition to the dev team, we interact with the test manager often. By "we" I mean me since I do the build stuff and give him the builds to test. Trial 1: The other developer on my team and I have both tried to talk to our manager about our team leader. About two weeks before release we went in his office and had a closed door meeting before our team lead got to work. We expressed our concerns about the product, its release date and our team leader. We expressed our team leader had a "rosey" image of the product's state. Our manager seemed to listen to what we said and thanked us for taking the initiative to speak with him about it. He got us an extra two weeks before release. The situation with the leader didn't change. In fact, it got a little worse. While we were using the two weeks to fix issues he was slacking off quite a bit. Just to name a few things, he installed Windows 8 on his dev machine during this time (claimed him machine was broke), he wrote a plugin for our office messenger that turned turned messages into speech, and one time when I went in his office he was making a 3D model in Blender (for "fun"). He felt the product was "pretty good" and ready for release. During this time I dealt with the test manager on a daily basis. Every bug or issue that popped up he would pretty much attack me personally (regardless of which component the bug was in). The test manager would often push his "views" of what needed to be done with the product. He virtually ordered me to change text on our installer and to add features to the installer and administration client. I tried to express how his suggestions were "valid ideas" but it was too close to release to do those kinds of things and to make matters worse, our technical writer had already finished documentation and such a change would not only affect the dev team but would affect the technical writer and marketing as well. I expressed I wasn't going to make those changes without marketing's consent as well as the technical writer and my manager's. He pretty much said I don't care about the product and said I don't do my job. I would like to take a moment to say I take my job seriously and I do my best. I am the kind of person that goes to work 30-40 mins early and usually leaves 30 minutes later than everyone else. Saying I don't care or do my job is just insulting. His "attacks" on me grew from day to day. Every bug that popped up he would usually comment on in some manner that jabbed me and the other developer. "Oh that bug! Yeah that should have been fixed by now, figures! If someone would do their job!" and other similar kinds of comments. Keep in mind 8 out of 10 bugs were in the server and had nothing to do with me and the other developer. That didn't seem to matter.. On one occasion they got pretty bad and we almost got into a yelling match so I decided to stop talking to him all together. I carried all communication through office email (with my manager cc'd). He never attacked me via email. He still attempted to get aggressive with me in person but I completely ignore him and my only response to any question is, "Ask my team leader." or "Ask a product manager." The product launched after our two week extension. Trial 2: The day after the product launch our team leader went on vacation (thanks....). At this time we got a lot of questions from the tech support... major issues with the product. All of these issues were bugs marked "resolved" by our lovely team leader (a typical situation that often popped up). This is where we currently are. The other developer has been with the company for about three years (I've been there only five months) and told me he was going to speak with our manager alone and hoped it would help get our concerns across a little better in a one-on-one. He spoke with the manager and directly addressed all of our concerns regarding our team leader and the test manager giving us (mostly me) hell. Our manager basically said he understood how hard we work and said he noticed it and there's no doubt about it. He said he spoke with the test manager about his temper. Regarding the team leader, he didn't say a whole lot. He suggested we sit down with the team leader and address our concerns (isn't that the manager's job?). We're still waiting to see if anything has changed but we doubt it. What can we do next? 1) Talk to the team leader (may stress relationship and make work awkward) I admit the team leader is generally a nice guy. He is just a horrible leader and working closely with him is painful. I still don't believe bringing this directly to the team leader would help at all and may negatively impact the situation. 2) I could quit. Other than this situation the job is pretty fantastic. I really like my other coworkers and we have quite a bit of freedom. 3) I could take the situation with the team leader to one of the owners. I would then be throwing my manager under the bus. 4) I could take the situation with the test manager to HR. Any suggestions? Comments?

  • What kind of eye wear can I use to protect my eyes from being irritated from staring at a screen all

    - by dr dork
    Many of us stare at computer screens all day. Lately, my eyes have been irritated from prolonged staring at my computer screens. Does anyone use or know of any eye wear technology that helps with this? About five years back, I bought a pair of non-prescription eye glasses that had a no-glare layer put on them by an optometrist. It slightly helped, so I'm considering getting another pair. Is this the best option I have at this point? Thanks so much in advance for your wisdom!

  • Loading a dll from a dll ?

    - by Quandary
    What's the best way for loading a dll from a dll ? My problem is I can't load a dll on process_attach, and I cannot load the dll from the main program, because I don't control the main program source. And therefore I cannot call a non-dllmain function, too.

  • Why use "DLLSelfRegister" in VB deployment package?

    - by Craig Johnston
    Why would you use DLLSelfRegister in a VB deployment package? I am trying to sort out possible conflict problems with a calendar control: msacal70.ocx. Apparently there is a conflict with newer Office calendar controls. I noticed the setup.lst for the VB deployment package uses DLLSelfRegister for this control. What are the effects of allowing a DLL to self-register and would removing DLLSelfRegister cause the ocx to register during installation of the package?

  • How to automatically fix MISSING reference in a dll when a referenced library is broken in VB6?

    - by systempuntoout
    What do you do when you break compatibility on a common library used by many other libraries? What i usually do is: For every dll that reference the broken one Checkout dll Checkout vbp project Open vpb project with VB6 Ide Click on References button Uncheck MISSING reference and OK Click on References button Check references and OK Click on Make dll Close project This can be a pita activity, when you have many Dll to recompile and it can be error prone because you could miss some Dll (anyway we have continuous integration that alert this cases). What's your best practice to handle this scenario?

  • 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

    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!

He adds that process manufacturing organizations such as oil and gas, utilities, and chemicals must manage this level of investment in an environment of constrained capital markets, erratic supply and demand, aging infrastructure, heightened regulations, and declining global skills. In the following interview, Graham explains how the right enterprise project portfolio management (EPPM) technology can help the industry meet these imperatives. Q: Why is EPPM so important for today’s process manufacturers? A: If the industry invests US$38 trillion without proper cost controls in place, a huge amount of resources will be put at risk, especially when it comes to cost overruns that may occur in large capital projects. Process manufacturing companies must not only control costs, but also monitor all the various contractors that will be involved in each project. If you’re not managing your own workers and all the interdependencies among the different contractors, then you’ve got problems. Q: What else should process manufacturers look for? A: It’s also important that an EPPM solution has the ability to manage more than just capital projects. For example, it’s best to manage maintenance and capital projects in the same system. Say you’re due to install a new transformer in a power station as part of a capital project, but routine maintenance in that area of the facility is scheduled for that morning. The lack of coordination could lead to unforeseen delays. There are also IT considerations that impact capital projects, such as adding servers and network cable for a control system in a power station. What organizations need is a true EPPM system that’s not just for capital projects, maintenance, or IT activities, but instead an enterprisewide solution that provides visibility into all types of projects. Read the complete Q&A here and discover the practical framework for successfully managing this massive capital spending.

  • How to set up a personal Apple developer account now with an eye on transferring app ownership to a company later?

    - by Rinzwind
    I have two Mac applications that I wrote for my own personal use, but I'm considering polishing them up and giving selling them on the Mac App Store a try. It seemed very premature to consider what would happen if either app would become successful enough to make it possible to set up a business around it, or to sell it to another developer. That is, until I read that Apple doesn't make it easy to transfer app ownership. I'm not sure how to best register with the Apple Developer program now to avoid any possible hassle in this respect later. From what I understand, one can really only transfer ownership of a developer account. I'm not sure about the relationship between an Apple ID and an Apple developer account. Does this mean I should at least not use the Apple ID I'm already using for iTunes, but create a second one to use for registering as an Apple Developer? Is there any disadvantage to using separate Apple IDs like this on the same Mac (one ID for Xcode development, the other ID for iTunes/iCloud/App Store/...)? Should one go as far as having a separate Apple ID & Apple developer account per app one develops? Or is there some other solution to take into account the possibility of transferring app ownership?
