Force iexplore (from command line) to 32-bit mode

We have an online movie that displays full-screen. Instead of the now-standard flash-based fullscreen, which was not available when the movie was originally written, an ActiveX control is used to launch iexplore.exe in kiosk mode. A rewrite of the movie to fix this glaring problem is scheduled for Q1 next year. In the mean time, I nee...

Io does not compile on Mac OS X Snow Leopard.

I followed the instructions in the README, they are very simple cd build cmake .. make install The problem occurs after the make install command. Io will not compile, specifically because of the module CFFI. ld complains that my libffi.dylib is not 64-bit, and thus it won't link the .o files, and because of that, it then complains tha...

Why would some DLL functions fail on 64-bit Windows?

I'm trying to run some LotusScript code (very similar to Visual Basic) in Lotus Domino on Windows servers. The code calls some Windows API functions, and works fine on 32-bit Windows 2003 servers, but doesn't work on the one 64-bit server we've tried it on. Here's one of our external function declarations: Declare Function FindExecutab...

Developing for both 64-bit and 32-bit

I've read a lot on the subject of converting 32-bit to 64-bit. I use a lot of vendor hardware, and have finally obtained both 64-bit and 32-bit drivers for each. Moving from 32 to 64 seems like it will be an easy transition. The problem, however, is that we do not wish to "transition". We want to maintain both, side by side, without hav...

WMI Win32_PhysicalMedia SerialNumber

I am using WMI with C++ to get the physical disk serial number. On Windows 7 64bit, I get a string with the serial number. While when running the same application on a Windows XP 64bit machine I get a hexadecimal string with each char's values reversed. I have noticed 3 different behaviours so far: Windows 7 64bit String in correct ...

64 Bit P/Invoke Idiosyncrasy

I am trying to properly Marshal some structs for a P/Invoke, but am finding strange behavior when testing on a 64 bit OS.

Size of a C++ array in 64 vs 32 bit environment

Hi, suppose I have a class defined as follows class foo { char [10] bar; } How would the size of this class differ when in a 64 bit environment compared to a 32 bit one, assuming no padding/packing. I believe the 64 bit version of the class would be 4 more bytes in length since: The class must contain a char* in order to point ...

I am trying to write an x86 emulator in JavaScript for education purposes. I have already written a compiler and at the moment I am trying to write the x86 emulator in JavaScript.

Is there an easy way to build a 64-bit JD2XX DLL?

Hello, For accessing FTDI USB boards from Java applications, I'm using the JD2XX driver wrapper (JD2XX.dll). It works very fine on 32-bit systems, but when it is loaded from a 64-bit JVM, it says it is impossible for a 64-bit JVM to load a 32-bit DLL. Very understandable. To get past this little problem, I install a 32-bit JVM on the 64...

Using 32bit COM addin under MS Office 64 bit

FileSize Problem - Cocoa

Hello, I've written methods that help me get the size of files/folders and translate the result in a human readable string. Problem is, when this size exceeds about 2.1GB, the number returned changes to a random negative number, like "-4324234423 bytes", which is useless. Things I've found out about & done about this issue: 32GB is l...

Does everyone get the infinite "connecting to target VM" bug when using 64-bit windows Netbeans?

Netbeans offers 64-bit support. This is absolutely essential to my project, which must use more than 2 gigs of RAM. The major advantage of Netbeans is that it offers a profiler. However, when used in 64-bit mode, this profiler often goes into an infinite loop and show the message: "connecting to the target vm" for ten minutes until ...
