Memory allocated for music: 5 GB?

• Get the DLL string (memory allocated for DLL)

  Hi, I'm aware there are a lot of discussions around this topic, but there are a lot of variations and I've never used before LabVIEW, and I seem to have a hard time at a very basic level, so I hope someone can help me with the below simple specific test case to put me on the right track before I pull my hair remaining.

  I've created a DLL with a single function "GenerateGreeting". When it is called, it allocates enough memory for the string "Hello World!" \0"at the pGreeting of pointer, copy this string to the pointer and sets the GreetingLength parameter to the number of allocated bytes (in the DLL in the end, I want to use, there is a DLL function to free the memory allocated for this way).

  I created a header file to go with the DLL containing the following line.

  extern __declspec(dllimport) int __stdcall GenerateGreeting(char* &pGreeting, int &GreetingLength);
  

  I then imported the LabVIEW file using the import Shared Library Wizard. That created a "generate Greeting.vi' and everything seems somewhat sensitive for me (although this does not mean a lot right now). When I run the vi, the ' GreetingLength on ' display correctly '13', the length of the string, but "pGreeting out" shows only three or four characters (which vary in each race), place of the string that is expected of junk.

  The pGreeting parameter is set to the 'String' type, the string "String pointer C" format, size currently Minimum of 4095. I think the problem is that the DLL wants to allocate memory for pGreeting; the caller is supposed to pass a unallocated pointer and let the DLL allocates memory for the string the right amount, but LabVIEW expected the DLL to write in its buffer préallouée. How to with LabVIEW? Most of the functions in the DLL in the end, I want to use work this way, so I hope that's possible. Or I have to rewrite all my DLL functions to use buffers allocated by the appellant?

  The vi , header and the DLL are atteched, tips appreciated. Edit - cannot attach the dll or the headers.

  Although char * & pGreeting is actually a thing of C++ (no C compiler I know would accept it) and this basically means that the char pointer is passed as a reference. So, technically, it's a double referenced pointer, however nothing in C++ Specifies that reference parameters should be implemented as a pointer at the hardware level. So free to decide to use some other possible MECHANISM that takes the target CPU architecture support a C compiler constructor. However, for the C++ compilers, I know it's really just syntactic sugar and is implemented internally as a pointer.

  LabVIEW has no type of data that allows to configure this directly. You will have to configure it as a whole size pointer passed as a pointer value and then use a call MoveBlock() or the support VI GetValuePtr() to copy the data on the pointer in a string of LabVIEW.

  AND: You need to know how the DLL allocates the pointer so that you can deallocate it correctly after each call to this function. Otherwise you probably create a leak memory, since you say that the first 4 bytes in the returned buffer always change, this feature seems to assign to each run of a new buffer that you want to deallocate correctly. Unless the DLL uses a Windows such as HeapAlloc() API function for this, it should also export a function according to deallocate the buffer. Functions like malloc() and free() from the C runtime cannot always be applied in the same version between the caller and callee, so that calling free() by calling on a buffer that has been allocated with malloc() in the DLL may not work on the same segment of memory and result in undefined behavior.

• Maximum memory allocation for HP Pavilion dv7-7010us

  HP Pavilion dv7-7010us
  Windows 7 (64-bit)

  Hello!
  As shown in the topic, I'm looking for the maximum memory allocation for my new HP Pavilion dv7-7010us notebook.

  I am aware that my computer has two memory slots filled a 2 GB DDR3 SDRAM and a 4 GB DDR3 SDRAM.
  If anyone could also tell me the perfect combination of chip (2 x 4 GB, 2x16GB, etc.) to get the maximum memory allocation, that would be much appreciated. Thank you!

• Change the memory allocated for the graphics?

  Hi, I have an Equium A60-181 with graphics ATi Mobility Radeon 7000. For the moment, that this GPU is using 64 MB of my system RAM that result with only 448 MB of RAM (512-64) for Windows. For a video resolution of 1024 x 768 32 bit it's a ridiculous amount of memory since it only really requires 4 MB for this. I'm not interested in games or 3d graphics, so my question is if I can change the memory allocated to recover more memory system?

  see you soon,

  Richard S.

  HI Richard,

  ATi drivers include an improved graphics option devices-> display manager that allows the value of the AMU to change. My SA30 supports load 16 MB, 32 MB, 64 MB and 128 MB.

  The same value UMA adjustable in BIOS Setup Panel.

• HP Pavilion 15-n048: maximum memory allocation for HP Pavilion 15-n048

  Does anyone can tell me what is the maximum memory loss for HP Pavilion 15-n048

  Officially, 12 concerts. See the owner's manual here:

  Link repair manuals

  See page 47. Pavilion 15 manuals are often a bit difficult to understand, does not mean that they are sometimes a bit misleading. Some models are configured with one or two memory locations, so the first thing I would do is to open the Bay of memory and see if there are 2 slots for sure. Your laptop came with a single module of 8 GB DDR3 - 1600, then the question is whether you have an open slot. If so, the specs say you can add a module of 4 GB of the same speed and type. Others have reported success with the addition of a module of 8 GB for a total of 16 concerts. Attention to the black blocks how are on the side of the module that you already have. 8 unlikely, what makes low density. Get the same module 8 GB or 4 GB.

  Post back with any problems.

• Memory allocated for mobility radeon on Satellite A100-768 graphics card

  Hello, I am french and I have a Toshiba Satellite A100-768,
  graphics memory of my lapto is like this:

  Graphics processor / vendor: ATI Mobility Radeon X 1400 HyperMemory to 512 MB - PCI Express x 16
  Video memory: DDR SDRAM - 128 MB
  Maximum allowed size of RAM: 384 MB

  I am looking for the location of the adjustment of the exclussive of 384 MB RAM) I want to change this amount (in fact it is 384 and I want to reduce to 128 or 0 in order to keep only the 128 MB) I looked in the bios and I found nothing

  Thank you and excuse my English

  Hello

  It is not possible.
  As far as I know, you cannot change this value manually.
  The graphics card controls the HyperMemory and assigns this value automatically.

  If you want to have more RAM (main memory) and then update the modules of memory on your laptop
  2 GB (2 x 1024MB) are recommended.

  Good bye

• How to change the memory allocated for VCenter server, which is a virtual machine

  I'm trying reclassification of 3.5 to Vsphere 4.1 and I improved VCenter first, making it a virtual machine.  However, when I created the server I did not allocate enough memory for it and I'm getting errors.  How can I allocate more memory for the virtual machine while it is stopped?  I can not allocate more memory, except if it is closed, but with it being the VCenter server if I stopped him so that I can access with the Vi client.  Is there a service console command?  I searched for a few hours and found nothing.

  Thank you!!

  Discover what the vCenter ON WHAT VM ESX host is marked (e), connect directly to the ESX host and find the vCenter VM and make the change.

• Create endpoint network Stream - pre-allocation for strings

  Hello

  I would use really allocation entry mode to pre-allocate memory on my RT goal. My concern is how to allocate memory for the size of the string.

  Because of the documentation

  "pre-allocate specifies that memory allocation buffer occurs when the end point is created. Wired for the type of input data determines the amount of memory allocated for each item. If a greater element is added to the buffer during execution, the extra memory is allocated dynamically. "

  I understand that if I am wiring constant string to the category data, 40 to the size of the buffer I receive buffer to 40 channels. String but how long? A single character?

  I don't want to let the Manager of memory to run after the creation of endpoint, so I would allow large memory space (for example 40 string, 10 characters each).

  Is it possible to do constant connection string (for example with 10 characters) or I have to put my string specific to the cluster size?

  Another question of trival perhaps, is - it possible to check what size buffer was allocated by this VI?

  Kamil

  Hello

  Here is some additional information on the allocation of memory for network streams:

  http://www.NI.com/white-paper/12267/en/

  My guess is that in order to pre-allocate buffers to not scalar data types, you'll write 'false' elements of the size desired in the stream to read or to flush out these elements "dummy" bevore using the flow in normally.

  Best regards!

• Pavilion DV2700: HP Pavilion DV2700 - how to reduce the amout of memory live allocated for video card

  Hello

  Is there a way to reduce the amout of RAM allocated for video card? I don't play games so only 16-32 MB should be more than enough

  I have 4 GB of RAM and only 2.99 are available. I know that 6 GB for a 32 bit OS only 3, 4-3, are available.

  Thank you

  Adrian

  It is actually more like 3 - 3.5 GB so 2.99 is just where you expect to be with a 32 bit OS. There is no way to manually set the memory allocation.

• Memory minimum allocation for Vista Business Edition with Visual Studio 2008 VM?

  Long time listener, first time caller...

  Please excuse me if this question is answered somewhere else, I tried from Google and it came only with a response that was sort of what I was looking for, but was specific to a Macbook with Fusion...

  I want to create a Vista Business Edition (SP1) virtual machine with Visual Studio 2008 (which I think also is delivered with SQL 2005 Dev Edition) and I was wondering what the minimum memory allocation should be for this in order to make it work properly?

  Thank you

  Jim

  Hello and welcome to the forums.

  Amount of minimum support from Microsoft for Vista Business is 512 MB and 768 MB or more recommended for Visual Studio.  1280MB is the minimum.  Personally, I do not want anything less than 2 GB to a virtual machine with Vista and Visual Studio - 1 GB each.

  One of the great benefits of virtualization is that you can start this virtual machine with 1.5 GB and try it.  If the memory is not sufficient, then it is simple to give another 0.5 GB to the virtual machine and try again.

  Good luck!

• Change THE Memory Allocation 6.0.

  I own a 7 '' netbook Sylvania, with 128 MB of RAM and Windows CE 6.0 OS. There the cursor to change the memory allocation between the PROGRAM and the STORAGE, but it won't budge. To get YouTube running on this thing, I need to go 68 MB of RAM allocated to executing programs for about 130 MB, taking storage (use an SD card to make up the difference - easy). Is there a way to unlock the slide or modify the default setting through the registry hive files? I have already made some adjustments with explore in this way and have managed to add a file to it. I understand in hex. Thank you!

  Hello GusCD6,

  The best place to ask your question on Windows CE 6.0 is in the MSDN forums for the development of Windows Mobile. Click here for a link to the Windows Mobile Development Forum.
  They are there, the experts and would be better able to solve your problem of Windows CE and help answer your questions.

• Not enough space for music DB and must free up space

  My Sansa was working fine and then I downloaded music on the sansa. Then it says not enough space for music DB and I need to clear 90 MB. I was downloading music on the sd card in the mp3. Now when I plug it into my computer it will not sync with my Media Player. I deleted all my music from my Media Player and synchronize it manually upwards and it will not always remove the song on the sansa. Please help someone!

  Use the Format function in the settings menu to erase the memory completely and read this FAQ.

• Sansa Fuze 2 GB keeps closing "not enough space for music db" then it stops?

  Not say 'enough space for music DB'... then it stops is not allowing me to remove?

  Connect the player to pc and delete some songs in the player using the pc. Be sure to always leave a reasonable amount of free space on the drive (perhaps 70 meg?) then the player can build the database. If I had written the firmware, I would probably have reserved a certain amount of memory for the database, so when people full of songs as much as possible in the drive it would not encounter this problem.

• Not enough space for music db

  After I reformatted and loaded new firmware, I get a message ' ot enough space for music DB Please free 6 MB storage "when I select my player on my computor it says no disc. In disk manage ment is 0 space used gig s/b 8. Any help would be apprieciated.

  Yes I do in MSC mode. In fact I did it in through the Windows Recovery mode: switch to orange, press record and start at the same time. I'm not aware of sansa.fmt I'll look into it. What worries me the most, is that I'm only seeing 16mg of storage on a 8gig machine, I am afraid I can have blown memory storage. I had all kinds of problems with this machine mainly MTP mode and message code 10 on machines running Vista sp1 and 11 units media center. So I tried to format it and that's how I got here. I tried all the suggestions for the problem of PSG in FAQ nothing helps. It worked fine on XP and Vista A pre - sp1 machine. I think something has changed with media center 11 and PSG maybe a new driver. I have the same problem with my wifes (PSG 10 code) sansa, except that I have not formatted so it always works. I think we can be directed to the ipod if I can't get this resolved.

• The display of file space of total Information System Page after changing virtual memory allocation?

  I thought that I understood that I could set up a file.sys page on any available partition on Windows, if I wished, for example, to create more virtual memory or move a file to another drive. However the changes I make to my computer are not appearing in the system information, after a reboot - why is - this?

  I have successfully configured internal auxiliary training to take on a pagefile.sys when you use the system advanced settings in the computer file system properties. Page created on the auxiliary drive single file memory is equal to once and a half the size of the physical memory of the computer.

  As I had created a larger file of the Page on the auxiliary drive, I then decided to reduce the Page file on the boot up to 300 MB drive. When I did make changes, I clicked on the set then OK and then I rebooted the entire computer.

  After restarting the computer, I tried to check system information for a summary of the changes I had made to the file Page and virtual memory space and I was disappointed to see that the pagefile on the auxiliary drive does not show upward. Information system had just recorded space Page MB 300 in C:\pagefile.sys file, and there is no trace of the larger Page file that I created on the auxiliary drive. How is that?

  If I go back to the virtual memory window in advanced system settings, it clearly shows I changed two files Page. Yet in Information System shows only the boot Page file drive. How is that?

  I always use Internet Explorer with only 300 MB Page file space, and it works really faster than the default virtual memory allocation, however the system soon slows down after opening about 5 instances of Internet Explorer and the system starts asking to close application windows down to save memory. So why does the system not switch to use the Page file on the auxiliary drive?
