问题 Let's say I have a file called FooBar.java. When I open the file in a powershell window with > vim foobar.java and write the file after editing it, the file gets renamed FooBar.java -> foobar.java. If I open the file with > vim FOOBAR.java it gets renamed FooBar.java -> FOOBAR.java. So Vim changes the name to be case sensitive to how I spelled it when I opened the file with a powershell command. This is undesired behaviour for me, and I did not have this problem earlier, before I did a clean

问题 I have attached a ContextMenuStrip to a Chart control. How can I get the chart control coordinates where the top left of the ContextMenuStrip is located when it appears? This is the point I want to translate to chart coordinates: 回答1: Using the answer to query the current mouse cursor position in the Opening event of the ContextMenuStrip can deliver the wrong position when opening the strip is delayed a bit. If you need the really clicked position, remove the ContextMenuStrip from the

问题 I know there are ways of using Tensorflow in C++ they even have a documentation for it but I can seem to be able to get the library for it. I've checked the build from source instructions but it seems to builds a pip package rather than a library I can link to my project. I also found a tutorial but when I tried it out I ran out of memory and my computer crashed. My question is, how can I actually get the C++ library to work on my project? I do have these requirements, I have to work on

问题 According to the documentation, QCameraInfo::availableCameras should return list of available cameras. There's no catch to it according to the docs. But still, I have two webcams and the array of available cameras is returned empty. What can I do? Is this even in the scope of programming, or does this mean Qt only supports limited subset of webcams? The OS I'm using right now is Windows 7x64. 回答1: I have this Problem too.Then I read about the example. I found that once you have declared

问题 I know this kind of questions are asked frequently, but I think this one is a little different and needed to be asked. The new Windows console supports ANSI (VT100) control codes: ANSI/VT100 control codes & Windows document: the control codes. However, ESC[2J doesn't really "clear" the screen, it just scrolls down to "hide" printed contents. Only ESC[H + ESC[J really "clears" the currently showed contents on the screen. Is this a bug or it is designed to do this? Is it written on some kind of

问题 I am running a Python script that launches a number of apps. I need a way to detect if the app that's launched has crashed. Some apps have internal crash handling How can I detect the crash? 回答1: If they have internal crash handling, it's not possible to detect. The application will handle the error and exit normally. You can't even detect this if you would attach yourself as a debugger. The reason is exception dispatching (MSDN): the debugger gets informed about an exception. This is called

问题 A process is terminated successfully or abnormally on some OS, when does an OS decide to wipe out the memory (data, code etc.) allocated to that process; at exit or when it wants to allocate memory to a new process? And is this wiping out memory allocation procedure the same on all operating systems (winXP, Win7, linux, Mac)? I understand, page table has mapping of virtual addresses for that process and actual physical addresses in the memory. Thanks. 回答1: How an OS reclaims process resources
