I need to write a simple visualizer for my mesh toolkit. The objects I'm working with is always located inside [-1,1]^3 box (inclusive), so I need to ensure that object will be entirely visible by user. I also want to have a possiblity to rotate a camera around object like user is "flying" around object. That's how I'm doing this: stat...
How do I expose a class from a dll ? The application importing the dll should be able to create the objects of the class and also he should be able to call into the member functions of the class . Is it similar to exposing C type functions using _declspec(dllexport) ? And also when I built the dll ( which only contains class definit...

In an application I wrote a few years back I use function SystemParametersInfo with SPI_GETPOWEROFFTIMEOUT to get the timeout for monitor off. On Vista this doesn't work anymore. So I decided to make this work on Vista, but after a few hours I feel like I'm no closer to a solution. Most of the functions I am going to mention are descri...
I was certain that somebody would have specifically asked this question, but from what I can see no-one has (there's been a question about learning win32 but that doesn't cover whether it's worthwhile doing so). I am very interested in gaining a deeper understanding of all the systems I use (I mostly program in C#, at least professional...
I'm noticing a pretty strange bug with tkinter, and I am wondering if it's because there's something in how the python interacts with the tcl, at least in Win32. Here I have a super simple program that displays a gif image. It works perfectly. from Tkinter import * canvas = Canvas(width=300, height=300, bg='white') canvas.pack() ...

Our win32 applications (written in C++) have been around for over 10 years, and haven't been updated to follow "good practices" in terms of where they keep files. The application defaults to installing in the "C:\AppName" folder, and keeps application-generated files, configuration files, downloaded files, and saved user documents in sub...

The following code implements a simple singleton that ensures only 1 instance of my application can be run. However, if another instance is started, I need to be able to grab that instance's command-line arguments, pass them to the initial instance, then terminate the second instance. The issue comes in when I'm attempting to get hold o...
I have a native C dll that exports one function besides DllEntryPoint, FuncX. I'm trying to find out how FuncX communicates with it's caller, because it has a void return type and no parameters. When I call it from a C# harness, I get an AccessViolationException - Attempted to read or write protected memory. I have a hunch that its cl...
I am using fopen fseeko64 ftello64 fclose etc. to operating on a file. How can I truncate a file? I know that there is no standard way to do this in C. All I want is some way that will work on any win32 platform. I'm using mingw gcc to compile. Please note: I meant truncate the size of the file to a specified size, not make it 0 size. ...

So I'm almost done an assignment involving Win32 programming and sockets, but I have to generate and analyze some statistics about the transfers. The only part I'm having trouble with is how to figure out the number of packets that were sent to the server from the client. The data sent can be variable-length, so I can't just divide the ...
If a Windows application has the IMAGE_FILE_LARGE_ADDRESS_AWARE set in the image header (via the /LARGEADDRESSAWARE compiler flag), this is typically to allow a 32-bit application to use more than 2GB of memory (only makes sense if the 32-bit Operating System has set the 3GB switch in boot.ini). See MSDN article /3GB for more info. My ...
