  • MS Access 2003 - Help understanding the structure of mdb, mde and be.....

    - by Justin
    Hi. I was just wanting some explanation as to what is going on once you have split your tables out into a back end file, and set an mde out for use. When a user accesses the mde, is the mdb still required to get to the tabes (or in order to make it work)? Let say I put these access apps on a shared drive for folks to use. If I split the be end on to the shared drive, and placed the mde on the shared drive, would I the mdb have to exist for that version mde to work (communicate with the tables)? Or does the mde sort of speak to the mdb which speaks to the tables? Hope this question makes sense. Thanks

  • How to relink existing shared library with extra object file

    - by awy
    I have existing Linux shared object file (shared library) which has been stripped. I want to produce a new version of the library with some additional functions included. I had hoped that something like the following would work, but does not: ld -o newlib.so newfuncs.o --whole-archive existinglib.so I do not have the source to the existing library. I could get it but getting a full build environment with the necessary dependencies in place would be a lot of effort for what seems like a simple problem.

  • win8: access denied to external USB disk; update access rights fails

    - by Gerard
    I use to work with 2 laptops (vista and win7), my work being files on an external usb disk. My oldest laptop broke down, so I bought a new one. I had no option other than take win8. 1/ I suspect something changed with access rights, as my external disk suffered some "access denied" problem on win8. I was prompted (by win8) somehow to fix the access rights, which I tried to do, getting to the properties - security. This process was very slow and ended up saying "disk is not ready". Additonnally, the usb somehow was not recognized anymore. 2/ Back to win7, I was warned that my disk needed to be verified, which I did. In this process, some files were lost (most of them i could recover from the folder found00x, but I have some backup anyway). Also, I don't know why, but under win7, all the folder showed with a lock. 3/ Then back again to win8. Same problem : access denied to my disk + no way to change access rights as it gets stuck "disk is not ready". Now I am pretty sure there is some kind of bug or inconsistence in win8 / win7. I did 2/ and 3/ a few times. At some point, I also got an access denied in win7. I could restore access rigths to the disk to "system" (properties - security - EDIT for full control to group "system" ...). But then I still get the same access right pb on win8, and getting stuck in the process to restore full control to "system" -- and "admin" groups. Now, after I tried for more than 3 days, I am losing my patience with that bloody win8 which I did not want to buy but had no choice. I upgraded win8 with the windows updates available. Does not help. Anybody can help me ?

  • Can't connect to SQL Server 2008 - looks like Shared Memory problem

    - by Proposition Joe
    I am unable to connect to my local instance of SQL Server 2008 Express using SQL Server Management Studio. I believe the problem is related to a change I made to the connection protocols. Before the error occurred, I had Shared Memory enabled and Named Pipes and TCP/IP disabled. I then enabled both Named Pipes and TCP/IP, and this is when I started experiencing the problem. When I try to connect to the server with SSMS (with either my SQL server sysadmin login or with windows authentication), I get the following error message: A connection was successfully established with the server, but then an error occurred during the login process. (provider: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.) (Microsoft SQL Server, Error: 233) Why is it returning a Named Pipes error? Why would it not just use Shared Memory, as this has a higher priority order in the list of connection protocols? It seems like it is not listening on Shared Memory for some reason? When I set Named Pipes to enabled and try to connect, I get the same error message. My windows account is does not have administrator priviliges on my computer - perhaps this is making a difference in some way (as some of the discussions in this post about an "SuperSocketNetLib\Lpc" registry key seems to suggest).

  • Instantiating class with custom allocator in shared memory

    - by recipriversexclusion
    I'm pulling my hair due to the following problem: I am following the example given in boost.interprocess documentation to instantiate a fixed-size ring buffer buffer class that I wrote in shared memory. The skeleton constructor for my class is: template<typename ItemType, class Allocator > SharedMemoryBuffer<ItemType, Allocator>::SharedMemoryBuffer( unsigned long capacity ){ m_capacity = capacity; // Create the buffer nodes. m_start_ptr = this->allocator->allocate(); // allocate first buffer node BufferNode* ptr = m_start_ptr; for( int i = 0 ; i < this->capacity()-1; i++ ) { BufferNode* p = this->allocator->allocate(); // allocate a buffer node } } My first question: Does this sort of allocation guarantee that the buffer nodes are allocated in contiguous memory locations, i.e. when I try to access the n'th node from address m_start_ptr + n*sizeof(BufferNode) in my Read() method would it work? If not, what's a better way to keep the nodes, creating a linked list? My test harness is the following: // Define an STL compatible allocator of ints that allocates from the managed_shared_memory. // This allocator will allow placing containers in the segment typedef allocator<int, managed_shared_memory::segment_manager> ShmemAllocator; //Alias a vector that uses the previous STL-like allocator so that allocates //its values from the segment typedef SharedMemoryBuffer<int, ShmemAllocator> MyBuf; int main(int argc, char *argv[]) { shared_memory_object::remove("MySharedMemory"); //Create a new segment with given name and size managed_shared_memory segment(create_only, "MySharedMemory", 65536); //Initialize shared memory STL-compatible allocator const ShmemAllocator alloc_inst (segment.get_segment_manager()); //Construct a buffer named "MyBuffer" in shared memory with argument alloc_inst MyBuf *pBuf = segment.construct<MyBuf>("MyBuffer")(100, alloc_inst); } This gives me all kinds of compilation errors related to templates for the last statement. What am I doing wrong?

  • shared memory STL maps

    - by user306963
    Hello, I am writing an Apache module in C++. I need to store the common data that all childs need to read as a portion of shared memory. Structure is kind of map of vectors, so I want to use STL map and vectors for it. I have written a shared allocator and a shared manager for the purpose, they work fine for vectors but not for maps, below is the example: typedef vector<CustomersData, SharedAllocator<CustomersData> > CustomerVector; CustomerVector spData; //this one works fine typedef SharedAllocator< pair< const int, CustomerVector > > PairAllocator; typedef map< int, CustomerVector, less<int>, PairAllocator > SharedMap; SharedMap spIndex; //this one doesn't work I get compile time errors when I try to use the second object (spIndex), which are someting like: ../SpatialIndex.h:97: error: '((SpatialIndex*)this)-SpatialIndex::spIndex' does not have class type It looks like the compiler cannot determine a type for SharedMap template type, which is strange in my opinion, it seems to me that all the template parameters have been specified. Can you help? Thanks Benvenuto

  • User Independant Share Folder

    - by ell
    At the moment, I have a folder in my home directory that is shared on my laptop and can also be accessed by the other windows desktop pcs in my network but now I have decided to make my home folder inaccessible by other users on my laptop so other people cannot look at my files if they have a user on my laptop. I set the permissions to none for everyone apart from me. I then changed the share folder (/home/elliot/Shared) to allow all access but my windows computers and other users on my laptop cannot access it even though they have the right permission, I think this is because they don't have access to the home folder in which the Shared folder is stored. Where should I store a new Shared folder on my laptop? Should I put it as /home/Shared? Or, alternatively is there a way I can allow other users to access my /home/elliot/Shared folder even if /home/elliot is inaccessible? Thanks in advance, ell.

  • Apache .shared folder

    - by Kevin
    There are already a bunch of rules in my Apache configuration. What I want to add is the following. There are some shared folders (.shared): /var/www/.shared/ and /var/www/.include/.shared/ and /var/www/.include/(.*)/.shared/. Now when someone visits http://domain.com/test.png it first executes the existing apache rules and will (when the file/folder was not found) look in those .shared folders. So suppose I've got this filesystem: /var/www/.shared/dog.png /var/www/.shared/test.gif and /var/www/domain.com/dog.png. Now when someone visits http://domain.com/test.gif, it must load the test.gif from the .shared folder. Now when someone visits http://domain.com/dog.png it must load the dog.png from the domain.com folder (because the existing apache rules will be executed first).

  • Access Denied using TakeOwn.exe

    - by Magnus
    I have got this file that I can't delete. It happened after a system crash, so the CHKDSK kicked in upon next reboot. After that, I can't delete the file. THis is on Windows Home Server, and the file is one of those hidden Thumbs.db, and my WHS reports a "File conflict" on the file, the reason: Access Denied" What I have tried so far, running as an Administrator: Delete: Access Denied TakeOwn.exe : Access Denied Attrib.exe -s -h : Access Denied Icacls.exe : Access Denied Re-boot in to safe mode and tried the above: Access Denied I have used the CHKDSK /f again, rebooted since some suggestions is that the file has been corrupted, but that didn't change anything. Any suggestions ?

  • Shared Data Source name error underscore characters added

    - by mick
    The name of our shared data source in RS (report server) is "AF1 Live Database" (no underscore characters - just spaces between words) and is the same in report builder in VS. However, the following error pops up when the RDL of this report is uploaded onto our company site and run. (error we are receiving...) The report server cannot process the report or shared dataset. The shared data source 'AF1_Live_Database' for the report server or SharePoint site is not valid. Browse to the server or site and select a shared data source. (rsInvalidDataSourceReference) We have no idea why the error reports the shared data source as 'AF1_Live_Database' with underscore characters? As this appears to be the problem that keeps the report from running we are seeking your help, thanks.

  • Cannot Open Shared Object cygmpfr-1.dll

    - by Nathan Campos
    I'm testing CeGCC, that is a gcc built to cross-compile applications to Windows CE devices. As everyone do to test compilers, I've done a Hello World program: #include <stdio.h> int main() { printf("Hello, World!"); return 0; } As I'm using Windows now(because this is my other laptop), I'm using Cygwin. But when I tried to compile I got some errors, as you can see on the terminal log: C:\Dev\WinCE\Testarm-mingw32ce-gcc test.c /opt/mingw32ce/libexec/gcc/arm-mingw32ce/4.4.0/cc1.exe: error while loading shared libraries: cygmpfr-1.dll: cannot open shared object file: No such file or directory C:\Dev\WinCE\Test What can I do?

  • Enumerate shared folders on Windows with low privileges

    - by Phil Nash
    Using C++ (VS2008) I need to be able to enumerate all shared folders on the current machine and get or construct the local and remote names. We've been using NetShareEnum for this fairly successfully, but have hit a problem where we need to run with a user account with low privileges. To get the local path using NetShareEnum we need to retrieve at least SHARE_INFO_2 structures - but that requires "Administrator, Power User, Print Operator, or Server Operator group membership". I've been trying to use WNetOpenEnum and WNetEnumResource instead but I don't seem to be getting the local name back for that for shares either - and I can't seem to get it to enumerate just local resources - it goes off and finds all shared resources on the local network - which is not an acceptable overhead. So I'd either like help on where I'm going wrong with WNetEnumResource, or a suggestion as to another way of doing this. Any suggestions are much appreciated.

  • how to automate upsizing from Access to SQL Server?

    - by Arne
    Hi, I need to automate the migration from an Access (2003) to an SQL Server DB (2005 or 2008). The upsizing should be done automatically as part of a build process. I need that because there are 2 versions of the software, a single user rich client and a web version. Access DB is used for single user to minimize setup effort, SQL Server to improve performance and scaling with many simultanious users. Access should be the "leading" DB, meaning devs do changes in Access DB and those are propagated to the SQL server within the build process. Many changes will occur, so doing it manually is not an option. I am new to the Microsoft world, so I dont know appropriate tools for that. What tools can I use and how? I know how to do it (by clicking) with the upsizing assistant. Perhaps I can automate that somehow? Thanks in advance for your answers. Cheers, Arne

  • Shared library linking and loading in BusyBox 0.61

    - by Alex Marshall
    Does anybody know how the dynamic linking and shared library loading works in BusyBox 0.61 ? I can't seem to find how this is done. There's no 'ld' present on the embedded system I'm dealing with, nor is there an LD_LIBRARY_PATH variable set anywhere. My motivation for this is to be able to create a symlink in the /lib directory to another directory on a different device (with considerably more storage space) for adding in more shared libraries, as the file system that contains /lib is a ramdisk that gets reloaded on startup and is within a few kb of being completely full (so we can't add more libraries to the image, nor can we obtain devices with more memory for the ramdisk)

  • How to create Shared VB Array Initialisors for NerdDinner

    - by David A Gibson
    Hello, I am trying to work my way through the NerdDinner tutorial - and as an exercise I'm converting it to VB as I go. I'm not very far in and after having gotten past the C# Yield statement I'm stuck on Shared VB Array Initialisors. static IDictionary<string, Regex> countryRegex = new Dictionary<string, Regex>() { { "USA", new Regex("^[2-9]\\d{2}-\\d{3}-\\d{4}$")}, { "UK", new Regex("(^1300\\d{6}$)|(^1800|1900|1902\\d{6}$)|(^0[2|3|7|8]{1}[0- 9]{8}$)|(^13\\d{4}$)|(^04\\d{2,3}\\d{6}$)")}, { "Netherlands", new Regex("(^\\+[0-9]{2}|^\\+[0- 9]{2}\\(0\\)|^\\(\\+[0-9]{2}\\)\\(0\\)|^00[0-9]{2}|^0)([0-9]{9}$|[0-9\\- \\s]{10}$)")}, Can anyone please help me write this in VB? Public Shared countryRegex As IDictionary(Of String, Regex) = New Dictionary(Of String, Regex)() {("USA", New Regex("^[2-9]\\d{2}-\\d{3}-\\d{4}$"))} This code has an error as it does not accept the String and the Regex as an item for the array.

  • A quick design question about C++ container classes in shared memory

    - by recipriversexclusion
    I am writing a simple wrapper around boost::interprocess's vector container to implement a ring buffer in shared memory (shm) for IPC. Assume that buf is an instance of RingBuffer created in shm. Now, in its ctor, buf itself allocates a private boost::interprocess::vector data member to store values, e.g. m_data. My question is: I think m_data should also be created in shared memory. But it this a necessity? What happens if buf that was created in shm itself, allocates standard memory, i.e. using new. Does this get allocated on the calling process's heap? I don't think buf is allocated there so how come a data member that is private to an object not on a process's heap gets allocated there. I'm confused.

  • Shipping GNU/Linux Firefox plugin with shared libraries (for installation with no root access)

    - by Vi
    The application is a Firefox plugin (loaded from $HOME/.mozilla/plugins), so wrapper script that sets LD_LIBRARY_PATH is not an easy option. RPATH, as far as I know, cannot refer to $HOME and can be only absolue path. Firefox tries to dlopen it's plugin from ~/.mozilla/plugins but fails (because it depends on shared libraries installed somewhere in the user home directory). Modifying Firefox menu item to provide a wrapper (with LD_LIBRARY_PATH) around Firefox is too hacky. What should installer script do (without root access) to make standard firefox load plug-ins that depends on out shared library? Should I just try to make embed everything into that .so to remove dependencies? Should I try to make installer script to finish linking or patch RPATH during the installation phase?

  • Database caching on a shared host

    - by tau
    Anyone have any ideas how to increase MySQL performance on a shared host? My question has less to do with overall database performance and more to do with simply retrieving user-submitted data. Currently my database will create caches at timed intervals, and then the PHP will selectively access the static files it needs. This has given me a noticeable performance boost, but I am worried about a time in which I have so much data that having to read in big files in PHP will actually be slower. I am just looking for ideas for shared hosting solutions; I am not going to get my own server anytime soon. Thanks!

  • What's a good, threadsafe, way to pass error strings back from a C shared library

    - by PerilousApricot
    Hello, all- I'm writing a C shared library for internal use (I'll be dlopen()'ing it to a c++ application, if that matters). The shared library loads (amongst other things) some java code through a JNI module, which means all manners of nightmare error modes can come out of the JVM that I need to handle intelligently in the application. Additionally, this library needs to be re-entrant. Is there in idiom for passing error strings back in this case, or am I stuck mapping errors to integers and using printfs to debug things? Thanks!
