FindPattern and 64-bit

HM, as nobody answers my questions from 32 to 64-bit, I'll keep wondering:

Function FindPattern does not seem appropriate for 64 bit, because the starting index continues to expect a regular 'int '. 'Number of bytes' is defined as ssize_t, but this seems not very consistent, if I can start in the first 16 bits, but then extend to the 65 bit length; It is strange that it is not possible to start a length of 2 ^ 35 and looking for only 2 bytes...

In addition, using the argument 'number of bytes' said: the function returns an error if you pass a value greater than UINT_MAX.

On a 64-bit system, using, as required, ssize_t, UINT_MAX is a very small number...?

I completely misunderstood the idea of ssize_t or there are a few bugs in the implementation of the functions of 32-bit / 64-bit.

All of the functions of "String Manipulation" to which belong the two FindPattern and CopyString do not support strings longer than bytes INT_MAX. Note that StringLength (which is this set of eqivalent of strlen functions) returns an int. These functions have not been modified to support longer strings, because it was not expected that a program will work with any strings longer than 65 535 bytes in length. This conservative approach was taken to avoid unnecessary warnings when porting 32-bit code to compile in 64-bit mode. Consider the following line:

int len = StringLength (str);

When it is compiled in 64-bit mode, this line generates no new warnings. If StringLength had been changed to return a ssize_t, there would be a new warning to compiler on to value truncation (just as you saw during the passage of strlen in CopyString).

If you work with generic memory, rather than true channels, you are probably better off using the ANSI functions (e.g., memcpy, strlen, etc.).

    It does not say which version it has detected, I had, nor it does not say what architecture it detected, nor the ability to change the target to download if I download on another machine. Just a download button green big without telling me what version or the new firefox cpu I download is for. Can they make it worse? I need to know if they are shoving me a 32 or 64 bit program and what architecture they detected until I push the download button.

    Rather then clicking the Green download on mozilla.org button go to the systems & languages link below because it lists both 32-bit and 64-bit Linux builds in all locales.

  • Satellite A100 - need tools for Windows 7 and 64-bit drivers

    Hello

    I have W7 RTM from Technet, and I install 64-bit edition on my laptop ' Satellite A100 (PSAA9) "I need 64-bit drivers and 64 bit utility (value added package..), but I can't find them... value added 32-bit package does not work on 64-bit (installation is rejected) :/"

    Sorry, my English is very very bad

    Thanks for the tips

    I do not think that you will have success installing Win7 64 bit on an old system as the A100, you should install 32 bit Win7 and use Vista 32-bit drivers.

  • 64 bit preinstalled operating system and 32-bit recovery disc?

    Hello

    I saw (somewhere) that if you buy a laptop Toshiba with a 64 bit OS, you can create your own recovery discs, and you are given a 32-bit recovery disk by Toshiba in case you want to switch.

    Is this true and if so what models does this apply to?

    Thank you.

    Hi mate,

    Yes, maybe this information is just, but I can say from my own experience on some laptops like Qosmio X 300 models are delivered with both versions. This means that on first commissioning you can choose between 32-bit and 64-bit.

    In addition, if you create the Toshiba recovery disc, it creates two different discs: one for 32 bit OS and the other for the 64 bit OS.

    You can check this in specifications detailed on the Toshiba site. Just look for the laptop you want to buy and you can see what OS is delivered. ;)

    In the buttom is a buffer with the key number.

    I have the CD with Vista 32 and Vista 64

    1 is the number of the same key the 32 and 64-bit

    2. I would like to format the C drive.

    3. can I install Vista 64, from the CD?

    Thank you for your help

    No worries. Yes, you can perform an installation of Vista with the DVDs you have. You can reformat the hard drive as part of the installation.

    Before you start, go into the Device Manager to see what wireless adapter, graphics card and network card is installed and write it down. This will allow you to save time.

    You will need the following DVD that you said that the laptop came with...

    Operating system DVD of Windows Vista Business SP1 (64 - en)

    Application and Driver Recovery DVD 32-bit and 64-bit for Windows Vista

    Note the twenty five characters activation of license key before starting. Enter it on the request for the installation of Windows script. Once the installation is complete, use the disk to install the drivers. If HP Support Assistant is available on the disk driver and application, install also.

  • AHCI drivers for Windows XP Professional 32 and 64-bit

    Hi all

    I have a HP Pavilion p6 2355il desktop PC

    I want to use Windows XP Professional on my pc so I need driver AHCI for 32 and 64 bits at a time. Drivers must be ready for installation f6 Option (text-mode Setup).

    Thanks in advance
    Sunil [personal information]

    Hello:

    Here is the link to the AHCI drivers, you need for your PC.

    XP 64 bit is the first download.

    http://downloadcenter.Intel.com/Detail_Desc.aspx?agr=Y&ProdId=2101&DwnldID=21730&Keyword=Intel+Rapid+Storage+Technology+(Intel+RST) & lang = fra

    You must either wake all the drivers or use a USB FDD to install the AHCI driver specific necessary for your PC to the F6 prompt button which I think is the Intel (r) Desktop/Workstation/Server Express Chipset SATA AHCI Controller.

    You can check by going to Device Manager and click to expand the IDE ATA/ATAPI controllers section to see the name of the installed sata AHCI controller.

    This is the driver that you select in the list on the floppy drive if you use the method of installing the drivers floppy.

    If you would rather integrate the drivers, here's a guide to do it.

    Read the Intel section, and then follow the instructions in the document to integrate all the drivers.

  • Can I use Labview 2013 on 64-bit and 32-bit PC interchangeably?

    Hello

    I am running Labview 2013 basic package on Windows 7/64 bit laptop, which is not stored permanently in the laboratory.  I need to buy a 32 bit desktop PC to run a non-Labview application, but it would be very convenient to use the new 32-bit machine to run Labview also, since it WILL BE at all times in the laboratory.  Then I wouldn't have to connect or disconnect the laptop computer in the laboratory every time I do the development of the system.

    Can I load my version of Labview 2013 on a desktop Windows 7/32-bit and write/run system live even as I do on my laptop Windows 7/64-bit?

    If the 32-bit and 64 - bit are interchangeable, so, I would get a higher end 32-bit system.  If they aren't, then I get the cheapest available 32-bit system and dedicated to the non-LabVIEW application.

    Thank you

    Dave

    LabVIEW edition will almost certainly be the screws you develop using 32-bit executables on Windows 32-bit and 64-bit systems.  What will certainly be different is the LabVIEW runtime system, so be careful when you build executable files.  Certain pieces of evidence that this is probably, it's developed under Windows XP (32-bit) code will run fine on Windows 7/64 (in development Mode).

    Note that I'm assuming that you installed LabVIEW 32-bit on your system Win7/64 (although there is a 64-bit version of LabVIEW, my understanding is that he could not be "ready for Prime Time").

  • Cache objects VI shared between 32 and 64 bit?

    Transferred into the LAVA: http://lavag.org/topic/16349-vi-object-cache-shared-between-32-and-64-bit/page__pid__99898

    I am currently working on a major project that is to be deployed in 32 - bit and 64-bit flavors. This means that I must periodically switch between installed versions of LV to build.

    It * seems * that if I work in 32-bit BT, and then I close and re-open my project in 64-bit BT, that everything needs to recompile... even if I had only changed a few things since the last, I worked in 64-bit.

    It seems that while LV keeps a Cache of objects VI separate for each version of LV, that it does NOT keep a cache separate for 32-bit versions and 64-bit. Is this really the case?

    Fabric Hello,

    LabVIEW maintain separate caches for versions 32-bit and 64-bit of the same version, but in the same file. They are separate entries in the objFileDB. Because 32-bit and 64-bit are very different beasts, the project must be recompiled in order to adapt to the new platform every time that you open in a new environment. It is possible to separate the compiled source code code. Research in the other forum posts, this separation likely to cause a higher risk of corruption VI.

    Best,

    Just a single license of Windows.

    You can choose which version you want to install 32-bit or 64-bit; but not as well installed.

    If you want to change the version of bits at a later date, you will need to backup your data and do a clean install.
