• Visual C++ SSE3 architecture

  First, excuse me for my English but it isn't my native language Then... with Visual Studio .NET 2005, the C/C++ compiler can apply SSE and SSE2 optimizations via / arch:SSE and  / arch:SSE2 , can it also apply SSE 3 optimizations (there isn't any "/arch:SSE3") or does this *need* "manual" optimizations to the source code Thank you very much To get SSE3 in your code you need to use the instructions themselves via asm. Right now the compiler doesn't support SSE3 optimizations, but then again it takes a while for these things to get into any compiler. So if you want SSE3 optimized functions, ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Unresponsive Visual Studio during build

  I have a nice, dual-core build machine with RAID-1 Raptor 150 disks and 2 GB of RAM -- typically, I can keep working while building in the background on this machine. However, when using XNA to build the MC2 sample, the Visual Studio window was mostly unresponsive duing the 7 minutes and 14 seconds it took to build. Most of that was because it spent 532 seconds in the CreateTGL stage, during which clicking anywhere in the Visual Studio window did nothing. In fact, I got a task bar balloon telling me that "Visual Studio is busy; please report this problem to Microsoft if it happens often." I understand that this is a technology pre- ...Show All

• Visual Studio Multiple Project Creation Template

  I want to add several 'C# Class Library' projects (in one hit) to a particular 'Solution Folder' when the user chooses the Add submenu on the solution Folder I have setup a UnboundTemplateReference to provide the command to the Solution Folder's Add Menu - that's appears fine.

• Smart Device Development StringSplitOptions not working

  In my code I have the following line which splits a string into multiple strings using the end-of-line as a seperator: string [] reqStringArray = reqString.ToString().Split( new string [] { "\\r\\n" }, StringSplitOptions .RemoveEmptyEntries); According to the documentation this function is now supported in the Compact Framework 2 as well, but it doesn't seem to recognize the StringSplitOptions object: "The name 'StringSplitOptions' does not exist in the current context" The weird thing is that the Intellisense does have the StringSplitOptions object in the list when I type it. Any ideas why it is not worki ...Show All

• Visual Studio Express Editions Windows service application in Visual C# Express

  I'm trying to build a simple Windows Service application in Visual C# Express. I simply can't get started. The documentation mentions a NON -existent template, which makes it kind of hard. However, I can see there's a 'ServiceBase' item in the toolbox and I have a feeling that that's the way to go, but there's no documentation telling how to use that. If I start a Windows Form application, I can drop this 'ServiceBase' component on the page, but this must be the wrong approach. Can anyone point me in the right direction - a step by step approach to get started would be really nice (missing in the help files). What project ...Show All
