• .NET Development Bizarre .NET performance benchmarks

  While attempting to achieve a maximum performance in .NET code I have stumbled on a very peculiar effect. If you compile and run the following C# code, you get a better performance in Debug configuration than in Release configuration. Moreover, if you comment out any one of the unused (!) case blocks in the Distance method, you get 5-fold !! increase in the performance in the Release configuration. I would appreciate any explanation that anyone can offer. And it would be great to hear comments from the .NET development them if they are following this forum. Thanks, Victor P.S. I am using VS 2005 and Framework v 2.0.50727.42 using System; using System.Text; using System.IO; using System.Diagnostics; names ...Show All

• Silverlight (formerly WPF/E) Creating controls without XAML?

  I assume this might be coming in a later release, but it seems like an unecessary restriction to be required to create controls using XAML (i.e. CreateFromXaml). A method that just takes a typename and a namespace might just be more natural for programming against: function Create(tagName[, namespaceUri]); The nameSpaceUri param is optional and defaults to XAML's v1 namespace when not specified. This way I don't have to think in XAML so much and can just think about creating my instance by type and go off an set the properties using JavaScript. Just thinking out loud, Drew Thanks for the feedback, Drew. We may be adding the functionality you describe in the future... we tackled "createFro ...Show All

• Visual Studio Tools for Office Document level customization slow loading time

  Hi We are facing serious performance issues with document level addins for Office 2003 and VSTO2005. It take very long time for word to START loading the customization assembly (in some cases, even up to 2 minutes) I have been reading some posts on the subject and we have been following MSDN best practices and recommendations as close as possible. Especially followed this useful link: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=290423&SiteID=1 and that is where I learned about the "PIA certificate trick". Still, even after implementing this, I still see the same behavior. Feeling in a deadlock at the moment since I am running out of fresh ideas – any help wil ...Show All

• Visual C++ Mixed mode C++/CLI idiom

  In my C++/CLI components, for each component I create a ref CLR class and a C++ class, the latter which does most of the internal processing and interfaces to the C++ standard library and 3rd party libraries such as Boost. I do this so I can use C++ libraries in my CLR component, especially when the .Net framework does not offer all the facilities which 3rd party C++ libraries have. In order to allow the C++ class to access the properties, methods, and events of the corresponding CLR class I have a pointer to the C++ class as a private member of my CLR class and dynamically create an object of the C++ class, passing a pointer ( ^ ) to the CLR object to the constructor of the C++ class, and assign the resulting C++ object to the pointer in ...Show All

• Visual C++ About DLLs adres space(wrong information in MSDN?)

  Hi Please look at this MSDN page http://msdn2.microsoft.com/en-us/library/d1587c1h.aspx here it writes: "An application can have multiple instances of itself running in the system simultaneously, whereas a DLL can have only one instance." But here http://www.windowsitlibrary.com/Content/356/03/1.html#3 it writes: "Under Windows 95/98, the operating system DLLs, such as KERNEL32, USER32, and GDI32, reside in the shared address space, whereas in Windows NT these DLLs are loaded in the process’s private address space. Hence, under Windows 95/98, it is possible for one application to interfere with the working of another application." So in winnt systems a DLL can have multiple instances.Right If true so is MSDN information page wrong Which on ...Show All

• Visual Studio 2008 (Pre-release) Schema Crawling Question

  Hey there team, If I wanted to get the names of fields that comprise a key, what's the preferred way of doing that :) I've been crawling around in the MetadataWorkspace, and boy there's a lot there. Might be beneficial to have some sort of post that outlines the big concepts with this namespace... Thanks! Mike You need to look for the type in "CSpace", not in "OSpace" (of course, those terms are not supposed to surface in the API :), so you may need to tweak the function a bit in order to find the entity type.
