The general strategy I/we use in most (cross platform) applications/projects is: We just use UTF-8 (I mean the real standard) everywhere. We use std::string as the container and we just interpret everything as UTF8. And we also handle all file IO this way, i.e. we expect UTF8 and save UTF8. In the case when we … Read more
malloc tries to allocate a contiguous memory range, and this will initially be in real memory simply due to how swap memory works (at least as far as I remember). It could easily be that your OS sometimes can’t find a contiguous block of 10gb of memory and still leave all the processes that require … Read more
You can use EnumDisplayDevices to figure out what displays you have available and EnumDisplaySettings to get a list of available resolutions for your displays. Use ChangeDisplaySettings to set the resolution you need.
Applications that use fixed coordinates and sizes will look small on high-DPI resolutions. Although even if using layouts there are some issues regarding element and font sizes and margins. Fortunately there is support for high-DPI displays since Qt 5.4 as there has been many high-DPI issue fixes. An application on Windows can assume one of … Read more

This makes symlinks created and committed e.g. under Linux appear as plain text files that contain the … Read more
Windows services cannot have GUIs, so you will need to either get rid of the GUI or separate your application into two pieces – a service with no UI, and a “controller” application. If you have the source code, converting the non-GUI code into a service is easy – Visual Studio has a ‘Windows Service’ … Read more

It’s not working because the entire for loop (from the for to the final closing parenthesis, including the commands between those) is being evaluated when it’s encountered, before it begins executing. In other words, %count% is replaced with its value 1 before running the loop. What you need is something like: setlocal enableextensions enabledelayedexpansion set … Read more
Handle should do the trick. Ever wondered which program has a particular file or directory open? Now you can find out. Handle is a utility that displays information about open handles for any process in the system. You can use it to see the programs that have a file open, or to see the object … Read more
The permissions article mentioned in the answer by Houari and Flimzy is a good reference material, but a direct answer (the quick fix I used) is: Right click the folder containing the data file(s) that permission was denied to and then click Properties. In the Folder’s Properties window, select the Security tab. Click the Edit … Read more
