64-bit

问题 Hi I have a following problem. I've created a project in 32 bit operating system. There I have installed EF 4.1 and SQL CE 4 for 32 bit. I've created a test table and launched it. Everything works, i.e. there is a connection to db and CRUD operations happen. In the reference pane I've set the copy local property for binaries EntityFramework.dll , System.Data.SqlServerCe.dll and System.Data.SqlServerCe.Entity.dll to true. Then I copy pasted the project into machine with x64 OS. It gives me the

问题 I am sequentially processing a large file and I'd like to keep a large chunk of it in memory, 16gb ram available on a 64 bit system. A quick and dirty way is to do this, is simply wrap the input stream into a buffered input stream, unfortunately, this only gives me a 2gb buffer. I'd like to have more of it in memory, what alternatives do I have? 回答1: How about letting the OS deal with the buffering of the file? Have you checked what the performance impact of not copying the whole file into

问题 I'm trying to develop a simple WCF service running in a 64 bit environment. I fire up VS2010 under Windows 7 New Solution -> WCF project -> Run -> It works fine. As soon as I change the properties of the project in order to make it compile in 64 bit, running it throws the following exception: Could not load file or assembly 'WcfService2' or one of its dependencies. With the following Assembly Load Trace === Pre-bind state information === LOG: User = ***** LOG: DisplayName = WcfService2

问题 So I am working on a simple .NET program for work and hit a bit of a weird roadblock I can't figure out. The application makes use of a configuration file which adds applications to a dropdown menu. However, before it's added to the menu, it does a system.io.file.exists to verify that the file exists, at least at the time the menu is created. However, System.IO.File.Exists(@"C:\Windows\System32\SnippingTool.exe") returns false, but the executable is there. Likewise, stikynot.exe also returns

问题 I have an old project which uses a 32 bit dll. This works fine on 32 bit processor, however when I install the same project on a 64 bit OS it does not work. Is there any way to convert 32 bit dll to 64 bit? Is there an alternative solution solution to make my 32 bit dll work in a 64 bit OS? 回答1: Your 32 bit dll should work just fine on a 64 bit machine as long as it is loaded into a 32 bit process - attempting to load a 32 bit dll into a 64 bit process will fail. If your project is a .Net (e
