access to a dll problem


I build table inside a loop. Really what you do here are all similar to this in C:

for (i = 0; i< len;="">

{

OPTR = realloc (optr, (i + 1) * 4);

OPTR [I * 4] = 0;

OPTR [I * 4 + 1] iptr = [I * 3];

OPTR [I * 4 + 2] iptr = [I * 3 + 1];

OPTR [I * 4 + 3] iptr = [I * 3 + 2];

}

I think you can see what the problem is with that.

Instead, you want to do something like this:

It's about a factor of 100 faster on my machine than your original idea.

  • Simultaneous access to a DLL using the JNA

    Hello

    I'm working on a Java project where I use JNA to load a library (.dll) that implements several functions for a VME bus. The project works well, without any other application requiring access to the VMEbus (ie using the same dll). However, the project that I am is supposed to be launched with the other applications that use the same dll. In this case, it seems that the FMV locks the dll file, and then other applications no longer work because they cannot access the dll.
    The JVM wants exclusive access to the DLL, but of course that he will never go. How can I get my program to access the dll of simultaneously with other applications without locking?
    I already looked in the java security policy and the Security Manager, but no idea at all, so any help would be appreciated.

    Thank you very much

    Kind regards

    Assuming this is true, there is a point that I still don't understand: how the operating system can grant (read) access to the dll several programs in C++, but it cannot load the dll for java programs and c ++ both ? Is a conflict between java and c ++ at the same time trying to load the same library as possible?

    Because programming is difficult, computers are far from perfect and the operating system doing its best in this imperfect environment.

    Instead of trying to blame the technology (which will be don't get you anywhere), think about it for a minute. Which can be a difference between C++ and Java applications? I can cite one that is likely, but I can't know for sure that this is the case due to a lack of information from you:

    -your C++ applications bind to the DLL at the time of Assembly (IE. you include a lib in your project)
    -Java binds to the DLL at runtime using LoadLibrary

    I'm not saying that it is a possible cause, I just try to open your eyes a little. There are things to discover. To be read on the operating system with the dll works until you can actually find. But whatever you do, stop blaming technology.

    Time machine is unable to perform a backup. Not able to access the sparsebundle. First of all, there is problem with the Snow Leopard operating system. Dragon followed in the upgrade to El Capitan. Only difference was error code 109 changed to 'null '. What about someone?

    We need some info.

    You can access from the finder Time Capsule? If this isn't the case, then Time Machine will not work.

    You upgrade the computer snow to El Capo and keep the same name?

    If you want to backup, it is best to start again... clean the new backup any attempt to add a previous backup failed.

    I recommend that you actually erase the TC... do a complete factory reset and start again.

    The previous backup if necessary can be archived on a USB drive connected to the TC assuming that Airport utility can still access it. Airport utility accesses the TC?

    With update installs all sorts of things can go wrong... so tell me more if you can not get anywhere.

  • Ke24xx.dll problem Keithley

    Hello

    We use the library for the development of a program ke24xx.dll own .vi who commanded the operation and the measures of resistance. However, two days ago, the program has begun to measure evil, i.e. the extent of the window of the façade of the instrument didn t match the value sent to the PC.

    We use a NOR-GPIB-USB-HS and we installed the driver NOR-488. 2 (the same that was used until the occurrence of the gap) and we tested the unit with other programs based on the same library one another NOR-GPIB-HS and another laptop. All the tests were wrong.

    On the other hand, we tested the same configuration by using the supplied 2.0 Labtracer by Keithley (it is developed with Labview so I understand it uses the same driver) and this test gave good results, the measurement from the front of the unit correspond to the extent of the data sent.

    We do not understand what is happening. Has anyone had the same problem? It is possible that the library may be corrupted?

    We used different computers, different GPIB-USB devices and the problem is the same

    Is this what we can test? Could it be related to the pilot (incompatibility between 488.1 (keithley) and NOR-488. 2?)

    Thanks in advance

    Sorry, he worked the problem was the unit GPIB protocol. It should be selected on the mode of the SCPI.

  • No sound, unable to update windows, a variety of error codes and dssenh.dll problems... Help?

    I'm running a Toshiba with Windows Vista. The 24th of this month, I have installed the updates for my computer, but when I rebooted I had absolutely no noise. I double checked to make sure it was not cut, I uninstalled and reinstalled the drivers, and then I tried to do a system restore. None of them worked.

    Then I tried to check updates more see if this would help to solve my current problem and began to find more mistakes, such as "could not find updates, error code: 800 b 0001 ' or 'Code error 8024402F' these are mistakes that I see most.

    Then when I go to open certain programs I get errors that say something about ' bad image: problem with Dssenh.dll "when I try to save it again, I get other errors with about 5 other .dll files.

    Of course, I went to the Microsoft website long enough... and I went through multiple options and steps, but nothing helped. So I thought that my last option is to ask.

    The last thing I can find is to download the "System update readiness Tool" to check for problems.

    Well, I can't download or run because of my error '800 b 0001'.

    I don't know what I would do at this point... Help?

    Before the update from the update began when my computer was being restarted... I had a black screen and had a weird three-step process that was supposed to be recommended. Meanwhile, there was a flood of information that crosses the screen.
    I ran a scan complete antivirus just in case, but it could be a virus that has not been detected?

    If anyone has any information, it is greatly appreciated... I don't know what to do.

    1. download the McAfee Consumer Product Removal, save it to your desktop tool: http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe

    2. close all open applications (that is, anything with an icon on the taskbar).

    3. click right on the file saved in #1 above, and then select run as administrator to run the utility. DO TAP not your keyboard until the race ends, then restart.

  • I am trying to run Halo 2 on windows 7 n 64-bit OS. MFPlat.dll problems

    I am trying to run Halo 2 on windows 7 n 64-bit OS. The game installs properly and is registered. When I start the game it says the the mf.dll and mfplat.dllfiles are absent. I downloaded both of dll.com and install in my system 32 file and file of halo 2. The message I get now is that "point of entry" is missing from the file mfplat.dll.

    Hi, Landon5050,

    If you get to the missing file mf.dll errors or any other errors with the mf.dll file, we suggest that you re-install the program, uninstall and reinstall a newer version, or check to see if updates are available for the program associated with the file instead of trying to copy a new version of the file on the computer. File errors are often caused by more than just a missing or corrupt file and copy a single file could cause more problems.

    http://www.computerhope.com/cgi-bin/process.pl?p=MF.dll

    These dll files exist in Windows, but there are also in the Halo installation directory. The equipped versions of Halo are older and is not compatible with Win7.

    Rename the files in your directory of Halo or replace them with newer versions of your directory %windir%\sysWOW64 or % windir%\system32.
    http://www.computing.NET/answers/gaming/Halo-2-missing-DLL/11709.html

    For re - save these files follow this step:

    1. Click Start, click principally made programs, accessories, right-click Guest, and then click Run as administrator.

    2. type regsvr32 mf.dll and then press ENTER.

    3. new type regsvr32 mfplat.dll and then press ENTER.

    There is a patch for this game as well. Have you tried to install the patch and check if it helped.

    Here is a link to download the update for this game.

  • Microsoft Access with ActiveX control problems

    I did a bit of research on this topic and have found several answers that are nearby, but do not address my real problem.

    I would use ActiveX control Microsoft Access, especially to create new database files without having to copy an empty file that I've stored somewhere I also can't stand it when I don't get something to work, so it's now something personal also.

    Anyway, when I run a simple VI to open the reference can be created, Access._Application, I get the error: "error 3005 occurred at the opening of the Automation: object specified is not can be created in Access.vi. I have tried many of the common responses to this problem, such as navigation for the library in ActiveX window and try to save it with regsvr32, but the file is msacc.olb, which cannot be registered with regsvr32.exe. I have attached the original VI and I tried on 3 different PCs, all with slightly different installs of Office, but with Access 2007. If anyone can help me understand this point, I would be very happy.

    Thank you

    Your vi made the same error on my machine.  Then, I removed the Access._Application reference, click right on the reference entry and chose to create a control.  Then I changed the Active-X class by accessing my version of reference computers ("Access._Application.12").  The same vi took place without error.

    The class is still shows as Access._Application, which indicates that there may be an incompatibility which is not visible.

    When and activeX node does not work when copied from any other machine, it is recommended to replace each node that is generating the error and reselect the properties and methods.

  • 2009 DLL problems

    I am trying to import a dll in 2009,

    I used tools, import, hsared library (.dll), then I do not get a choice on the next window "specify create or update mode" is selected. On the next window, I put the path to the dll and header. There are them an another windo with 'include path' and "preprocessor definitions", if I don't choose anything here and click next then presented dll functions have an x beside them on the next window.

    I have attached the manual which includes some other tips programming but for VB and C++.

    Header to be used with mtb.dll file
                                                                         
    typedef bool (* Type_InitMotoBee) ();
    typedef bool (* Type_SetMotors) (on1 int, int speed1, int on2, speed2 int, int on3, int speed3, on4 int, int speed4);

    typedef void (* Type_Digital_IO) (int * inputs, outputs of int);

    This file has two problems. The first is the use of the bool data type that is only a C++ data type but not a datatype C standard. I do not think that the Import Wizard supports this, but the solution would add a function defined as #define bool char to her sets the framework of the Import Wizard.

    The biggest problem is that it only defines the function pointer types, but not the function prototypes.

    You can fix this by adding following line at the end:

    bool InitMotoBee (void);
    bool SetMotors (int on1, int speed1, int on2, speed2 int, int on3, int speed3, on4 int, int speed4);

    void Digital_IO (int * inputs, outputs of int);

    With that and the bool according to define in the settings of the Import Wizard it should work
