The latest computer configuration is better than a few years ago, the use of XP system is no longer suitable for the full performance of the computer, so the Win7 system is currently the best choice. Win7 and the previous XP system, also divided into several versions, now users generally choose win7 32-bit or 64-bit sy
It is easy to use C # To implement the reading and writing of the Registry. I will not explain it in detail here.
Using C # To operate the registry, the two main functions are as follows:ProgramNote: To introduce the Microsoft. Win32 namespace ):
1: Read the key value --> registry. localmachine.Opensubkey(".. Key Path... ", true). The meaning of the 2nd Boolean parameters here is: indicates whether the opened key value can be changed (that is, whether setvalue () can be used to assign values

Since the XP system, the 64-bit system has introduced new technolo
First of all, I believe that the choice of 64-bit WINDOWS7 users in a large proportion of memory is greater than or equal to 4GB. Under 32-bit Windows7, it is possible to show that memory can be used 3.25G, which makes many netizens feel uneasy. Yes, addressable memory space is indeed the most notable feature of the
First, the original design is different. The 64-bit operating system was designed to meet customer requirements for mechanical design and analysis, three-dimensional animation, video editing and authoring, and the need for large amounts of memory and floating-point performance in areas such as scientific computing and high-performance computing applications.
Second, the configuration requiremen
If you had an existing 32-bit ArcSDE installation, you cannot directly upgrade to a 64-bit installation.If you is running ArcSDE as a 32-bit application connecting to an existing 32-

Difference 1: the original design intention is different. The 64-bit operating system is designed to meet the requirements of mechanical design and analysis, 3D animation, video editing and creation, as well as customer requirements that require a large amount of memory and floating point performance in scientific computing and high-per
The difference between 32-bit systems and 64-bit systems has the following four points:
First, the CPU requirements are different

64-bit Advantage: 64-bit applications can directly access 4EB of memory and file size up to 4 EB (2 of 63 power); Access to large databases. This article describes the 64-bit under C language Development program considerations.1.3
Because of the dynamic library called in the project, these dynamic libraries are placed under C:\WINDOWS\SYSTEM32, but when deployed to a 64-bit machine may be problematic, recently this problem has been tangled for a long time, in the native 32 for the system test dynamic call DDL successfully, deployed to 64-
64-bit Advantage: 64-bit applications can directly access 4EB of memory and file size up to 4 EB (2 of 63 power); Access to large databases. This article describes the 64-bit under C language Development program considerations.1.3

A very professional question. Because the article introduced 32 and 64-bit CPUs
x86 is the standard abbreviation for Intel processor-based systems. X has nothing to do with the processor, it is a simple wildcard definition for all *86 systems, a serial number of Intel general-purpose computers, and a common set of computer instructions, since early Intel's CPU numbers are numbered as 8086,80286, Because this entire series of CPUs are instruction-compatible, so use X86 to identify the set of instructions used today Pentium, P2,P4, Celeron series are supporting the X86 comman
C + + simply defines the relationships between these basic data types, and does not define the word length that strictly defines them. On different platforms, depending on the compiler's implementation, their word lengths are shown in the following table:

Memory support: 32-bit Windows system can only run or process up to 4GB of memory, when the computer installed more than 4GB, the system will not recognize more than 4GB of memory. Also said is installed >=4GB above memory, installed and not installed is the same.
While the 64-bit system may support more than 4GB of m
Simply put, x86 represents a 32-bit operating system x64 represents a 64-bit operating system. If your CPU is more than two cores, it certainly supports 64-bit operating systems. If your computer has more than 4G of memory, it wil
