问题 I know I can change my wine PATH through regedit, but I actually need to change the PATH just for a single run. For example, I have my software called frontend.exe , this depends on example/mylib.dll , I need to invoke frontend.exe with example/ on PATH. But I may not set this on the registry be cause this configuration is just for this application, not for every wine application... 回答1: Wine supports the WINEPATH variable. If, in your Unix Shell, you export WINEPATH, once you launch wine it

问题 Is there a Windows API function that I can pass a string value to that will return a value indicating whether a file name is valid or not? I need to verify that a file name is valid, and I'm looking for an easy way to do it without re-inventing the wheel. I'm working in straight C, but targeting the Win32 API. If there's no such function built-in, how would I go about writing my own? Is there a general algorithm or pattern that Windows follows for determining file name validity? 回答1: The

问题 My setup is zsh 5.0.5 in arch linux I have set the PATH variable as below in .zshenv typeset -U path path=(~/bin $path) DW=$HOME/Downloads but it didn't work. print $PATH shows only /usr/local/bin:/usr/bin:/usr/bin/vendor_perl:/usr/bin/core_perl .zshenv was read, because I could see DW variable is set. Only PATH variable isn't set. And what I don't understand is, after rename the .zshenv to .zshrc, PATH variable just works as intended. Need any special treatment setting environment variables

问题 This question already has answers here : PHP include best practices question (10 answers) Closed 7 years ago . I have been all over the Internet trying to figure out the best way to handle paths in my website. Should I use relative paths, absolute paths? I have seen dirname ( FILE ) mentioned several times. One problem I have with relative paths is that PHP files which are included by several other files at different directory levels cause the relative paths to break. For example if the

问题 I want the user to give me the full path where the file exists and not just the file name. How do I open the file this way? Is it something like this: ifstream file; file.open("C:/Demo.txt", ios::in); This doesn't seem to work. 回答1: Normally one uses the backslash character as the path separator in Windows. So: ifstream file; file.open("C:\\Demo.txt", ios::in); Keep in mind that when written in C++ source code, you must use the double backslash because the backslash character itself means

问题 I am currently creating an MVC 4 web application. I have an action that has a base background image which is always the same then an arrow image which changes in degrees depending on the information that is collected within the action. I call this action using <img src="@Url.Action("trend-image", "NonReg_Reports")" alt="background" width="245" height="105" /> This works fine when it is called and is just displaying a HTML webpage. It gives me the HTML. <img src="/nonreg-report/01495344/trend

问题 I'm grading C and C++ files for a class, and this assignment uses the GSL library. Since I don't have root permission on my computer, my GSL library is installed in my home directory, and thus I need to tell compilers and linkers where to find it. This isn't a problem when I write a program myself, because I just add the appropriate -L and -I flags to gcc. But when I'm compiling student's files, I don't want to edit every one of their makefiles. Instead, I want to put the appropriate
