I wanted to learn Lua so I bought a book. The problem I'm having is finding a compiler/interpreter. I downloaded the binary compiler for Windows from http://luadist.org/ (Windows x86 (MinGW32 4.7.1)). But every time I try to start it up I just says:
The program can't start because lua53.dll is missing from your
computer. Try reinstalling the program to fix this problem.
Which I did several times to no avail. I've tried to find another compiler but this seems to be the only one... which I find hard to believe. There are "demo" compilers but I want one I can install so I can do the examples in the book. There are instructions on how to "compile" the compiler at the Lua site on Linux and Mac machines but I'm working on a Windows machine.
Any help?
ZeroBrane Studio is the best for Lua. It works on Windows, Mac, and Linux. It was specifically designed for beginners, but it a full featured IDE for writing and debugging Lua code.

Be sure to try the "Run as Scratchpad" feature which provides a "live-coding" experience.
We are trying to move an old client application from one PC to a new windows 7 64 bit PC. At the time the software was developed we used QBFC version 5 to interact with quickbooks, however it appears now that we can no longer do so. I attempted to register the interop.qbfc5lib.dll after installing the QBFC5 installation package and we still receive an error message. I've also attempted installing the most recent version of the SDK to the system and upgraded the QBRPXML2 to the most recent version. The client is now running QB2013 on the server and has updated his data to this version.
The error we are receiving is: "Retrieving the COM class factory for component with cLSID {4877276c-486d-b201-f096035ca4df} failed due to the following error: 80040154.
Suggestions other than recompile the code?
I had this problem with a client who I had used QBFC 8 and he had switched to a new computer. I didn't do a lot of research, but it appears that the installers that Intuit has on their websites use different CLSID than I originally had built against. I just downloaded and installed QBFC 5, which I didn't have anything installed for, and it shows the following CLSID in the registry (I'm on Windows 7 64-bit):
QbFC5.QBOESessionManager {86AC2FAD-C987-4757-B591-02F9867A8BE5}
QbFC5.QBSessionManager {4877276C-A727-486D-B201-F096035CA4DF}
The only thing I can think of is that the COM files that were originally installed on your development machine have been changed in a later installation. For my client on QBFC8, I simply switched to using QBFC12 and recompiled the code.
Is it technically possible (I don't think this would be restricted), and how do you go about it?
I got my little test app building fine, but when I run it I get a failure dialog.
The debug output is slightly more informative:
The thread 0xe4c has exited with code -1073741515 (0xc0000135).
The program '[3400] OpenCVTest2.exe' has exited with code -1073741515 (0xc0000135) 'A dependent dll was not found'.
Then I created a Win8 Desktop app, which also built fine but failed to run.
MSVP100D.dll is part of the VC++ 2010 Redistributable which is not compatible with Win8. (Being a hacker I tried it anyway, the installer runs to completion - but the bits aren't installed.)
Is there a compiler flag I can try? Possibly a custom build of OpenCV would fix it, but that would be a last resort, and it might only fix the desktop app.
This guy shows an example of using OpenCV library for performing face detection in a Windows 8 Store app written using C++/CX:

Also, at the below post he also describes how the C++ Runtime works for Windows 8Store apps:

MSVP100D is not a part of VC10 redist. Note the "D" at the end of its name. That package only includes release builds. Your release builds should work fine. But mixing libraries from different VC versions might get you in trouble. See this. Your best chance is to build from source with VC11.
I wish to register some of status of my application as a performance object, so that I can monitor its performance by utilising the Windows Performance Monitor.
But I had a problem with Windows 7: the performance object cannot be seen in the list of Performance Monitor, even if my application is running.
My code is exactly the same as the Delphi project in this tutorial:
http://www.wehlou.com/Code/perfmon/index.htm
However, the solution provided in this tutorial doesn't work in Windows 7 either.
Such solution works fine in Windows XP and 2003.
I don't know if there are some changes in Windows 7 which makes my performance object missing.
Please help. Thanks a heap in advance.
Is your Windows 7 computer a 64-bits machine? You may have to provide both a 32 and 64 bits version:
http://msdn.microsoft.com/en-us/library/windows/desktop/aa371636(v=vs.85).aspx
The short answer:
Yes you can fix manually the 2 object performance counters (DeltaCount & RawCount) issue under Windows 7 x32. The 2 files generated by PerfMonClient.exe are usable (namely symfile.h and symfile.ini).
Nota: Refer to MSDN for the usage of lodctr.exe.
Prior to that an entry to the registry as follows should created:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\PerfMonClient\Performance]
"Open"="PerfData_Open"
"Close"="PerfData_Close"
"Collect"="PerfData_Collect"
"Library"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,\
74,00,25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,50,\
00,65,00,72,00,66,00,4d,00,6f,00,6e,00,44,00,4c,00,4c,00,2e,00,64,00,6c,00,\
6c,00,00,00
Nota: Library point to %SystemRoot%\System32\PerfMonDLL.dll (location of the performance DLL).
Any attempt to install and/or uninstall them using PerfMonClient.exe App doesn't work even under Windows XP. Forget about that.
Look an feel:
Listing
symfile.h:
#define OBJECT_1 0
#define DEVICE_COUNTER_1 2
#define DEVICE_COUNTER_2 4
symfile.ini:
[info]
drivername=PerfMonClient
symbolfile=symfile.h
[languages]
009=English
[text]
OBJECT_1_009_NAME=PerfMonTest Performance Counters
OBJECT_1_009_HELP=A demo application for your unbridled pleasure
DEVICE_COUNTER_1_009_NAME=RawCount
DEVICE_COUNTER_1_009_HELP=A count of something that goes up and down
DEVICE_COUNTER_2_009_NAME=DeltaCount
DEVICE_COUNTER_2_009_HELP=Something going up all the time, Windows shows difference per time unit
I am having trouble with OpenCV2.0 on Win7 32bit, I have recompiled it using MinGW 4.5.0 and everything went OK until I tried to run examples. Anytime it opens NamedWindow it crashs down. On the other side on on different machine Win7 64 bit everything runs without problem. Any idea?
Thx, Jan
It is a known problem due to some sort of "stack misalignment" with SSE under certain circumstances.
It has been posted before namedWindow() causes crash in opencv 2.3.1? (Eclipse+MinGW on XP, C++)

Check that you are picking up the correct DLLs, and if you built with Qt, that you are getting the correct Qt DLLs.
Did you just install somethign that also uses Qt - but a different version (like AMDs codeprofiler)
