allocation of memory for the pointer in the dll

• Allocation of memory for a class system (avoid new/delete)

  My plugin has been crashing a lot, but only under Windows. I realized that the culprit is in my code for the creation of a bitmap GDI + drawing.

  The code I use is:

  ...

  Bitmap image * tempImg = NULL;

  try {}

  tempImg = new Bitmap (width, height, bitmap_bytes_per_rowL, PixelFormat32bppPARGB, reinterpret_cast < BYTE * > (bitmap_dataP));

  } catch (A_long & e) {}

  Return PF_Err_OUT_OF_MEMORY;    Assuming that...

  }

  If (tempImg! = NULL) {}

  canvas = Graphics::FromImage (tempImg);

  delete tempImg;

  }

  In this case, bitmap_bytes_per_rowL has been calculated before, and bitmap_dataP refers to the memory correctly allocated (via host_new_handle()) where the drawing will happen. tempImg is an object Bitmap GDI + Windows, that is only used to create the object Graphics "canvas." Once it has achieved its objectives, it will be deleted.

  I'm 99% sure that it is the cause of my crashes. It crashes all the time and it is more likely when the code is compiled in release mode.

  So, I have two options:

  -Allocation of memory for the Bitmap object using host_new_handle (sizeof (Bitmap)), and lock up the handle to get a pointer to my bitmap object. Problem, it is, how to initialize, because I will no longer use the keyword "new"?

  -Create my Graphics 'canvas' object without starting by creating a Bitmap object. That would be my preferred method, but the only other way to create a Graphics object is via an HDC and HWND, neither of which I know how to access and then how do I associate my (real) memory of drawing?

  Thanks for the tips!

• recommendation of the memory for the guest operating system

  Hi guys,.

  I need some advice

  I have a pile of vsphere 5 made of 2 servers on each server that I have on 5 VM

  (1) domain contoller 2008 standard edition + dhcp + dns

  2) exchange 2010

  (3) file server

  My question is what is the recommended memory and cpu for these VM configuration? I'm a bit confused

  What happens if I don't set up the limits and booking hotel and leave all default? What is the point of the week in this configuration? If I leave all default each VM does not use memory a cpu as it needs?

  Thank you specify in advance

  To add the tips of memory... Many people allocates memory for the virtual machines that will never be used, and ultimately you consume the memory of your host much faster than necessary. Start low when allocating memory to a virtual computer. Adding memory is simple to make, after you have collected on the functioning of your host performance data. The Performance tab will show you what is happening.

• Installation Partition problem (allocated too expensive for the Service Console?)

  Installation Partition problem (allocated too expensive for the Service Console?)

  RAID1 (15K 146 GB SAS) on Dell R710 and VMFS is on table EQL.

  What I did during the ESX4.1 excavation, it's that I have used ALL the space in 146 GB (mainly for / and / var), after adding this ESX host to vCenter, VC and EQL ASM/VE started to complain about the following points:

  1 VC: health check of localstorage warning (only has 245 MB left on 146SAS localstorage)

  2 EQL ASM/VE: warning rootFolder folder (due to the above)

  I thought that he is authorized to use all the space for / (50 GB) and / var (50 GB) in my case for only 146 GB, I don't think I need to leave any space on the installation disc.

  Could someone share some lights here?

  Thank you

  As you can see SDS use all the SDC VMFS partition space.

  This create the alarm.

  The thing really confused me why I have to leave a space on the disk at all?

  Technically there is no reason to let the space... but also no reason to have a big service console

  Usually, you need 10 to 20% free space for each snapshot data store and Exchange files... but in your case, you will not have these files.

  If you have any problems, but you receive the alarm until you do not disable them on this specific data store.

  PS: I suggest you switch to ESXi, is quite simple and it doesn't have this strange vmdk for the "console".

• Allocation of memory to the VM

  I have a Windows 2003 virtual machine with memory following values:

  Memory active: 357MB, granted memory: 2 GB.

  When I look in the Task Manager I see a process uses 1.2 GB of RAM.

  How it is possible to have a process consuming 1.2 GB if Active memory is 357 MB? The VM not the paging memory inside the guest OS.

  What you see in the Task Manager, is the amount of virtual memory is allocated/paid to the process.  This does not mean that memory is very active.  In addition, memory is granted in pieces, and therefore generally a page is marked in memory for the entire piece.  Thus, pieces is awarded under a page are marked.  Thus, memory granted to a process does not always mean memory actively used.

• HP recovery D needsrepairs says not enough memory for the backup

  need to know which files can be deleted or how re-branded more memory for this partition without damaging it.

  Do not delete anything and do not write something here! And do
  do not try to assign any disk space more (it is not called 'memory' on a
  hard drive) to it.

  It is a recovery partition; its purpose is to provide what you need
  to reinstall Windows if it should be necessary. Anything for her and
  you will lose this ability.

  Your computer comes with instructions on how to write its contents
  on a DVD so that you would be able to reinstall Windows if your drive is dead.
  Which should have been the first thing you did when you got the
  computer, then do so immediately as soon as possible.

  And another point: backup to a second partition is by far the
  form of backup is the lowest. It's better than no backup at all,
  but barely. I do not recommend backup a second not removable
  hard drive (or worse, a second partition on your hard drive only)
  because it leaves you likely to be simultaneously the original losses
  and backup for many of the most common hazards: severe defects of power,.
  nearby lightning, virus, attacks even the theft of the laptop.

  In my view, secure backup must be on a unguarded and removable media
  in the computer. For backup really secure (required, for example, if the)
  the life of your company depends on your data), you should have several
  generations of backup and at least one of these generations must be
  stored off-site.

  My computer is not used for business, but my personal backup plan
  use two identical removable hard disks, I alternate between the two,
  and use Acronis True Image to create a complete copy of the primary
  drive.

  I also use a 1 GB USB key pair to make more frequent backups
  my most sensitive data (for example, financial information). For this, I just
  Drag and drop.

• Fingerprint memory for the LabVIEW 7.1 development system

  Hello

  I would like to know the size memory for LabVIEW 7.1 full development System.Both during the installtion and to develop applications later.

  If anyone can help. Thank you.

  There is no one answer for this, as this varies considerably.

  For what is on the disk, if my memory serves, the 7.x base takes a few hundred MB, but which could greatly inflate according to the modules and drivers you add.

  For the RAM, I believe than 7.0 used to identify approximately 20-50 MB immediately after loading, but this number then would also change a lot over time depending on what you are doing. Loading, editing and execution of code just regularly change the amount of RAM used.

  Why do you ask? Also, are you aware that 7.1 is relatively old now (came out 7 years ago)?

• Reservation of memory for the server sqql

  Hello

  I am running two SQL servers with 4 virtual CPUs and each has 12G of RAM available.

  We have noticed that sql process uses only 180MB of RAM while SQL is designed to use all available memory... We decided to use a reservation of memory for these boxes and grant a full 12 GB for each booking.

  (1) that would be really useful?

  (2) I noticed that after having reserved memory, that the system has taken something like 10 minutes to start, can anyone explain to me why?

  Thank you

  The shares of resources can be adjusted if necessary. I don't think that you need. As well as the host has only a single virtual machine now, who knows what the future may bring. You add multiple virtual machines and you will start to do the math. ESX let his work resources and balance. If you see performance degradation then start looking at the distribution of resources.

  As for the CPU that the virtual machine is not the only object on the system might compete for processor resources, you also have the SC. When you give the VM 4 vCPU find the system to wait on the availability of all hearts.

  You can reduce the number to 2 and even play with the processor affinity if you want, you should try to determine the weather your SQL system really needs the CPU/MEM tweaks (in my experience IO is the cause of the headache of performance most SQL).

  Hello ric

  Sorry, but something like that is not possible. The only thing that you can develop is RAM.

  It is very interesting to know who they are. You're probably talking about the local dealer. I also heard that they often give some useful tips, information and suggestions.

• allocation of memory for a LStrHandle

  Hello

  I know that this thing about memory allocation and LStrings has been much already posted but I couldn t find the answer to my question.

  Currently I am working with an external code (c ++) and calling a function of vi.

  I want normal c ++ channels:

  (1) declaring normal c ++ string

  (2) conversion c ++ string in a Lstring + pass it as Lstringhandle (this works very well!)

  (3) initialize a Lstrhandle for my result (it would work very well if I knew that the length of the resultant Lstring! but because the application is set to call ANY function of vi I don't know what the function and so I do not know the length of the result string)

  My problem is really basic, but how do I get the actual length of the modified LString?

  Let´s tell my function of vi concatenates 2 strings and returns the result, then the signature of my vi-function should look like this:

  void __cdecl Concat (LstrHandle * string1, LStrHandle * string2, LStrHandle result);

  at some point, so I need to know the length of the result.

  Any ideas?

  (it is important that the strings are Lstrings and they are passed as pointers!)

  I've tried usinig labviews functions of manager, but this won't work for all of the problem this toddler is integrated.

  I appreciate the ideas and help!

  Thank you...

  If your function receives the string1 and string2 as input and returns the result, then the first two by reference and by value, it seems quite a bit back.

  Because string1 and string2 are entered, the function is supposed to use, they must be defined and allocated in any case properly by the appellant. But for output handles passed by reference, it is quite valid in LabVIEW since on version 6 to pass a NULL handle and LabVIEW code takes care of allocating a new handle in this case.

  So basically if you declare your function like that when, you create your LabVIEW DLLS:

  void __cdecl Concat (string1, string2 LStrHandle, LStrHandle LStrHandle * result);

  It is quite valid to call this function like this in your C code:

  LStrHandle string1; initialization of a string

  LStrHandle string2; initialization of a string

  Result LStrHandle = NULL;

  Concat (string1, string2, & result);

  and the result will contain a valid string descriptor on successful return.

  If the output parameter is declared by the value, then you obviously can't pass in a NULL handle because the function has no way to return a new handle. Then, you will indeed need to allocate an empty descriptor like this:

  LStrHandle result2 = (LStrHandle) DSNewHClr (sizeof (int32));

  This allocates a handle with the place for the numElm value and initializes it to 0.

• leak memory in the dll with a function imaq

  Hello

  I'm writing a dll that uses the imaqImageToArray function.

  Of course this function allocates new memory whenever it converts an image, and as I convert 180 photos per second and shopuld program run for hours is quite a problem for me.

  The solution must of course be the free function (void * MyPointer). If I use malloc to allocate some random memory, instead of the imaqImageToArray, it works perfectly.

  However, when I call free() to free the memory allocated by the imaqImageToArray function, the LabView/dll-program crash.

  So I wonder what function the imaq functions allows you to allocate the memory and how I can get rid of him again. Is there another imaq-function?

  Thank you already!

  Greetings

  Sorry everyone for disturb you.

  I was just stupid... the answer is of course imaqDispose(void *object)

  Sorry again

  Thanks for the help

• Nidll.TLC, was eliminated for the dll system RT?

  I am currently trying to call some model (*.mdl) in LabVIEW to transform the models of the dll.  The models are manufactured and converted with Mathworks Simulink and LabVIEW I intend to open via call library function node of the dll.  So far, I've downloaded NI Veristand and the model Interface Toolkit, which gave me options of file system target:

  NIVeristand.tlc

  NIVeristand_VxWorks.tlc

  But I don't have an option for nidll.tlc (I understand can be opend in LabVIEW Veristand instead), and I wonder why.  This option has been removed for RT targets?

  Hi Abe,

  Yes, nidll.tlc is obsolete as of 2012. In particular, nidll.tlc has been installed by the NI LabVIEW Simulation Interface Toolkit (SIT) which reached its end of life in 2012. SIT, however, was replaced by the model Interface Toolkit LabVIEW; This kit replaces nidll.tlc by NIVeriStand.tlc. Note that the interface of the model generated by nidll.tlc and NIVeriStand.tlc are very similar; Indeed, nidll.tlc was the NIVeriStand.tlc Foundation. A model generated by NIVeriStand.tlc can be opened in LabVIEW VeriStand.

  • The experience of the user to generate a model SL in a library, it's the same as it was with SIT (nidll.tlc). For more information: http://zone.ni.com/reference/en-XX/help/374160B-01/vsmithelp/mit_convert_model_to_dll/
