32bit-64bit

I am having a frustrating time with Blend reporting "Window is not supported in a Windows Presentation Foundation (WPF) project." due to unbuildable configurations but can't quite work out how to mangle my way out of it. I've worked out it is probably due to my trying to have a single solution with x86 and x64 configurations. There is no way to tell Blend 2 which is the active Solution Configuration and active Solution Platform . I think it's a bit of a weakness in the configuration system, or maybe the way I've set things up, but I have Debug64 and Debug solution configurations one of each is

I am trying to do matrix multiplication in Swift using the Accelerate framework. Used the vDSP_mmulD. This worked perfectly in the iPhone6 , 6 plus, iPad Air simulator (all 64 bit architecture) but did not work with any of the 32 bit architecture devices. It sees like vDSP_mmulD is not recognized by the 32 bit architecture and the program does not build. Error message displayed is "use of unresolved identifier 'vDSP_mmulD'" Has anybody else seen this error? Please let me know your thoughts. I am using Xcode 6.1. Thanks. Simple solution: use cblas_dgemm instead (also part of Accelerate). It's

Is it possible to determine whether Excel is running in 32-bit or 64-bit from the Microsoft.Office.Interop.Excel.ApplicationClass? Edit The solution should work for both Excel 2010 and Excel 2007 This code should give you the "bitness" of Excel. Microsoft.Office.Interop.Excel.ApplicationClass app = new Microsoft.Office.Interop.Excel.ApplicationClass(); if (System.Runtime.InteropServices.Marshal.SizeOf(app.HinstancePtr) == 8) { // excel 64-bit } else { // excel 32-bit } EDIT: here is another version that should work for previous versions of Excel as well. Just pass an ApplicationClass reference

I would like to install my USB device driver [.inf file] using PnPUtil.exe utility on both 32bit and 64bit systems for Windows Vista and Windows 7. I tested on my machine [Windows 7 32bit] and everything was fine because PnpUtil.exe is located in: C:\Windows\System32\PnPUtil.exe . But in 64bit Windows 7 the utility is not in this directory. When I tried installing driver on different Windows 7 - 64bit machine I could found PnPUtil.exe in this location: C:\WIndows\winsxs\amd64_microsoft-windows-pnputil_31bf3856ad364e35_6.1.7600.16385_none_5958b438d6388d15\pnputil.exe and the test was also fine.

I have a jnlp file for deploying my javafx 2.0 application, however, how do I make sure that the users have the correct javafx runtime (32 or 64 bit depending on the jvm present on the machine) and if not, download it and run the application. Assuming that the user does not have a javafx runtime currently installed, the problems that I'm facing mostly with a 64 bit machine with either 32-bit, 64-bit or both JRE's are: 1) The Javafx swing deployment guide mentions to use the <jfx:javafx-runtime version /> tag to download the appropriate jfx runtime, but JRE below 1.7 doesn't understand this tag
