  • Sharing memory between modules

    - by John Holecek
    Hi, I was wondering how to share some memory between different program modules - lets say, I have a main application (exe), and then some module (dll). They both link to the same static library. This static library will have some manager, that provides various services. What I would like to achieve, is to have this manager shared between all application modules, and to do this transparently during the library initialization. Between processes I could use shared memory, but I want this to be shared in the current process only. Could you think of some cross-platform way to do this? Possibly using boost libraries, if they provide some facilities to do this. Only solution I can think of right now, is to use shared library of the respective OS, that all other modules will link to at runtime, and have the manager saved there.

  • Struts 2 - Accessing different properties on the ValueStack sharing the same name

    - by veggen
    Struts 2 will resolve all property names during view rendering against the top object in the ValueStack first. But how can one access a property with the same name on the object lower on the stack? Example: Let's say I have an Action class called MyAction and it has a a logDate property. In the view rendered after this action is invoked, there's this: Now imagine a User object also has a logDate property. During the iteration, Struts 2 will always push the current user object to the top of the ValueStack effectively resolving all property names against it. But, what if I wanted to access logDate from the action? What's the correct way to do this?

  • Sharing Eclipse directory on Dropbox between Windows and Mac OS X

    - by sowbug
    This question was close to mine, but not quite. I have a Windows desktop and a MacBook Pro. I'd like to be able to keep my Eclipse workspace in my Dropbox folder. The problem is that many project settings change between platforms: references to JREs, JDKs, and other libs. Every discussion I've seen of this problem seems to suggest taking advantage of the source control system's ignore functionality, so that such-and-such file remains local-only and thus able to remain platform-specific. But when you're working with a real single shared folder, that class of solution doesn't apply. Have you had luck working with a Java Eclipse project living in a single folder shared over the network, cross-platform?

  • Sharing class member data between sub components

    - by Tim Gradwell
    I have an aggregate 'main' class which contains some data which I wish to share. The main class also has other class members. I want to share the data with these other class members. What is the correct / neatest way to do this? The specific example I have is as follows. The main class is a .net Form. I have some controls (actually controls within controls) on the main form which need access to the shared data. Main Form - DataX - DataY - Control1 -- Subcontrol1 - Control2 -- SubControl2 SubControls 1 and 2 both wish to access DataX and DataY. The trouble is, I feel like better practice (to reduce coupling), would be that either subcontrols should not know about Main Form, or Main Form should not know about subcontrols - probably the former. For subcontrols not to know about Main Form, would probably mean Main Form passing references to both Controls 1 and 2, which in turn would pass the references on to SubControls 1 and 2. Lots of lines of code which just forward the references. If I later added DataZ and DataW, and Controls 3 and 4 and SubControls 3 and 4, I'd have to add lots more reference forwarding code. It seems simpler to me to give SubControls 1 and 2 member references to Main Form. That way, any sub control could just ask for MainForm.DataX or MainForm.DataY and if I ever added new data, I could just access it directly from the sub controls with no hassle. But it still involves setting the 'MainForm' member references every time I add a new Control or Subcontrol. And it gives me a gut feeling of 'wrong'. As you might be able to tell I'm not happy with either of my solutions. Is there a better way? Thanks

  • Sharing base object with inheritance

    - by max
    I have class Base. I'd like to extend its functionality in a class Derived. I was planning to write: class Derived(Base): def __init__(self, base_arg1, base_arg2, derived_arg1, derived_arg2): super().__init__(base_arg1, base_arg2) # ... def derived_method1(self): # ... Sometimes I already have a Base instance, and I want to create a Derived instance based on it, i.e., a Derived instance that shares the Base object (doesn't re-create it from scratch). I thought I could write a static method to do that: b = Base(arg1, arg2) # very large object, expensive to create or copy d = Derived.from_base(b, derived_arg1, derived_arg2) # reuses existing b object but it seems impossible. Either I'm missing a way to make this work, or (more likely) I'm missing a very big reason why it can't be allowed to work. Can someone explain which one it is? [Of course, if I used composition rather than inheritance, this would all be easy to do. But I was hoping to avoid the delegation of all the Base methods to Derived through __getattr__.]

    I am a big fan of OneNote. Few weeks back I came across a forum where people had shared their OneNote notebooks. Now I am trying to search but unable to find that link. Does anyone know of any such/similar forum? Note: Can anyone add Tags oneNote or Microsoft-OneNote to this. Thanks.

  • Sharing folders with VirtualBox, Win7 Host and Ubuntu 9.10 Guest [closed]

    - by user225890
    I have a development setup from this tutorial: http://www.sitepoint.com/blogs/2009/10/27/build-your-own-dev-server-with-virtualbox/ But what I can't figure out is how to share a folder on my Ubuntu virtualized machine with the host Win7. I want to use a Windows text editor to edit code that's on my Ubuntu server. I've tried using the Shared Folders setting, adding "/var/www" but it says that the path is not absolute. When I click on "other", it only allows me to browse folders on my Win7 host. Both the host and guest are 64-bit OS. Thanks in advance!

  • Sharing Code, Images and Core Data models across iPhone and Mac project

    - by Robert
    Hi, I am maintaining a fairly large mac project and an iphone client for this project. Some code as well as some images and core data models are shared between these two projects. I want to create a shared framework containing this shared components but to my surprise, frameworks like we cocoa developers known them are not supported on the iphone os. Currently I see the following options: a) Include the files in both projects (much tedious work) b) Create a static library for both projects and manually copying the images/core data models c) Create a static lib for iphone and a framework for mac Any suggestions?

  • Sharing data between two instances in a load balanced java web application

    - by rabbit
    I want to cache data in a java web application deployed on multiple instances. We are using spring 2.5.6. What is the easiest caching library to configure and use with spring? I have heard of EH Cache, but the configuration is too cumbersome. The requirement is that a spring scheduler will run and set some flags. These flags are accessible from all load balanced instances. But since the scheduler runs only on one instance the flag is set only on that jvm. So how do i make these updated flag values available to all load balanced instances?

  • GIT sharing configuration data

    - by user569980
    Hi, I just started using GIT for my versioning and I want to program some tools that work on top of it. Here is my question: Which information in the .git/config is shared to a remote repo? Is any? Is there a special way to push information to that repo? The reason I am asking is that I would like to add a "unique stamp" to the config of a repo. Also the remote repo and everybody pulling that project should have the stamp. Is that possible? If not, is there any other way to identify a repository? Having a .git folder, I want to decide whether this git repo is the same as a previously specified remote repo (the same means created by pulling the remote repo, changes are okay, of course).

  • How to set up a file server in a restricted corporate environment

    - by Emilio M Bumachar
    I work in a big corporation, and the disk space my team gets in the corporate file server is so low, I am considering turning my work PC into a file server. I ask this community for links to tutorials, software suggestions, and advice in general about how to set it up. My machine is an Intel Core2Duo E7500 @ 3GHz, 3 GB of RAM, Running Windows XP Service Pack 3. Upgrading, formatting or installing another OS is out of the question. But I do have Administrator priviledges on the PC, and I can install programs (at least for now). A lot of security software I don't even know about is and must remain installed. But I only need communication whithin the corporate network, which is not restricted. People have usernames (logins) on the corporate network, and I need to use them to restrict access. Simply put, I have a list of logins of team members, and only people in the list should access the files. I have about 150 GB of free disk space. I'm thinking of allocating 100 GB to the team's shared files. I plan monthly backups on machines of co-workers, same configuration. But automation of backups is a nice, unnecessary feature: it's totally acceptable for me to manually copy the contents to a different machine once a month. Uptime is important, as everyone would use these files in their daily work. I have experience as a python and C programmer, but no experience whatsoever as a sysadmin, and almost nothing of my programming experience is network programming. I'm a complete beginner in this. Thanks in advance for any help. EDIT I honestly appreciate all the warnings, I really do, but what I plan to make available is mostly stuff that now is solely on DVDs just for space reasons. It's 'daily work' to read them, but 'daily work write' files will remain on the corporate server. As for the importance of uptime, I think I overstated it: a few outages are OK, it's already an improvement over getting the DVDs. As for policy, my manager is kind of on my side, I will confirm that before making my move. As for getting more space through the proper channels, well, that was Plan A, and it's still on the table... But I don't have much hope. I'm not as "core businees" as I'd like.

  • Share Folders & Files Between Vista and XP Machines

    - by Mysticgeek
    Since Microsoft has three operating systems in use, chances are you’ll find yourself needing to share files between XP, Vista, Windows 7, or some combination of the three. Here we take a look at sharing between a Vista and XP on your home network. Share Without Password Protected Sharing If you’re not worried about who’s accessing the files and folders, the easiest method is to disable Password Protected Sharing. So on the Vista machine open Network and Sharing Center. Under Sharing and Discovery make sure Network Discovery, File Sharing, and, Public Folder Sharing are turned on. Also turn off Password Protected Sharing… Now go into the Vista Public folder, located in C:\Users\Public, and add what you want to share or create a new folder. In this example we created a new folder called XP_Share and added some files to it. On the XP machine go into My Network Places and under Network Tasks click on View Workgroup Computers. Now you’ll see all of the computers on your network which should be part of the same Workgroup. Here we need to double-click on the Vista computer. And there we go…no password to enter so we can access the XP_Share folder or anything else that is located in the Public folder. Share with Password Protected Sharing If you want to keep Password Protected Sharing turned on, then we need to do things a little different. When it’s turned on and you try to access the Vista machine from XP, you’re prompted for a password, and no matter what you think the credentials are, you can’t get access…very annoying. So what we need to do is add the XP Machine as a user. Right-click on Computer from the Start Menu or desktop icon and select Manage from the context menu. The Computer Management screen opens up and you want to expand Local Users and Groups, then the Users folder. Then right-click any open area an select New User. Now create a new user name and password, you can also fill in the other fields if you want. Then make sure to uncheck User must change password at next logon and check the box next to Password never expires. Click the Create button and close out of the New User screen. You’ll then see the new user we created in the list and you can close out of the Computer Management window. Now back on the XP computer when you double-click on the Vista machine, your prompted to log in. Just type in the username and password you just created. Now you’ll have access to the Public folder contents. Set up Sharing on XP If you want to access a shared folder from the Vista computer located on the XP machine, it’s the same process in reverse. On the XP computer in Shared Documents, right-click on the folder you want to share and select Sharing and Security. Then select the radio button next to Share this folder and click Ok. Go into Computer Management and create a new user… Now from the Vista machine double click on the XP machine icon, enter the password, then access the folders and files you need. If you have multiple versions of Windows on your home network, you’ll now be able to access files and folders from each of them.

  • Running sfc /scannow provides the error The specific error code is 0x000006ba [The RPC server is una

    - by leeand00
    I think that my mup.sys file is corrupted, I received the following error when trying to access a network share that was located on my Windows 7 box, from my Windows xp box: No network provider accepted the given network path. After reading this I attempted to follow the directions by entering my computer into safe mode. After I run "sfc /scannow" I receive the following error message: The specific error code is 0x000006ba [The RPC server is unavailable]. Additionally when I go into Services, it says that the Remote Procedure Call (RPC) service is running but that the Remote Procedure Call (RPC) Locator is not running. When I try to start the Remote Procedure Call (RPC) Locator, it gives me an error saying: Error 1084: This service cannot be started in Safe Mode So what can I do about this exactly? If it can't find the Remote Procedure Call service in safe mode?

  • Windows7 - “The specified network password is not correct.” when the password is in fact correct.

    - by Win7 Home User
    I have a samba server setup for some time now. It is a Hardware NAS - which unfortunately does not provide access to the Samba logs. (the exact model of the NAS is called Addonics NAS Adapter ) I also have a Windows Vista and a Windows XP machine - from both I am able to map \\192.168.0.20\Smd with no errors ( net use l: \\192.168.0.20\Smd works, after asking for my username and password). I also bought a brand new computer, with Windows 7, and when I try to execute the same exact net use command on it - using the exact same username/password pair, I get a "The specified network password is not correct." message. I also tried mapping from the Windows explorer menu, and got the same error. I synchronized the clocks of the two machines, tried again... and yet the same error persists. So what is really surprising here is that mapping works from WindowXP and Windows Vista machines, but fails from a Windows7 machine using the exact same command and username/password - Anyone has any idea of what could be causing this or how to solve the problem? Thanks

  • Install Additional Printer Drivers (x86) on Vista (x64) - Can't find suitable (x86) ntprint.inf

    - by jmohr
    I have a printer connected to my computer that I'd like to share on my home network - shouldn't be a problem. The computer the printer is connected to is running Vista Ultimate x64. The computers I'm trying to share with are x86 Windows XP Professional and x86 Vista, so I need to install additional (x86) drivers. I checked the box to add x86 printer drivers and then it asked for the location of the drivers. I browsed to the location and clicked OK. It then prompted "Please provide path to Windows media (x86 processor). When I click "Browse..." it wants the location of a file named ntprint.inf It looks like it's asking for a Windows (x86) installation disk. I put one in but I can't seem to find this file on the 32-bit Vista install disk Where is the proper place to find this file?

  • Adding an user to samba

    - by JustMaximumPower
    I'm trying to setup some samba shares in my home network on an Ubuntu 12.04 machine. Everything works fine for my user account (max) but I can not add any new user. Every time I try to add new user they can not use the shares. It's likely that the error is very basic to the concept of samba but please don't just tell me to read the docs. I've been trying that for about 2 weeks now. I've set up the server with my user max who can mount transfer and the share max. Than I added the user simon with sudo adduser --no-create-home --disabled-login --shell /bin/false simon because the user should not be able to ssh into the machine. I did an sudo smbpasswd -a simon and set an (samba) password for simon and added an share for simon. I also added simon to transferusers to give him access to the share transfer. But simon can't connect to transfer or simons. ---- output of testparam: ------- Load smb config files from /etc/samba/smb.conf rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384) Processing section "[printers]" Processing section "[print$]" Processing section "[max]" Processing section "[simons]" Processing section "[transfer]" Loaded services file OK.
