groovy - renameTo() in grails to rename an apk file to zip file -


I want to upload apk files. And then to extract some information, convert it to Zip. I used the renameTo () function but it is not working 

  string newFilename = "new.apk" New file (f.getOriginalFilename ()) .name (new file (" New.apk "))

(f.getOriginalFilename () will revert the name of an APK file) How can I change the name exactly?

Understand that the given file is given a full path. For example 

  new file (webRootDir + "/" + [folder name] + "/" + f.originalFilename) .renameTo (new file (webRootDir + "/" + [folder] Name] + "/" + + appname + ".zip"))

will solve the problem.

c++ - Why does Visual Studio Release build break on non-executing code line -

When I created my C ++ program with the default release configuration in Visual Studio 10, I put a breakpoint on one line Who should never be reached. What confunded me was that when the program is running then it stopped at the breaking point. Adding a volatile statement and transferring this line to the break point does not break the execution of the code where the brake appears (though does not produce the same behavior as creating a minimum project with this function). Why is the "Release Debugger" (?) Step on this line and when executing breakpoints are executed? If I keep going after the break then false statement continues to return code execution. bool bounding box :: Cutting (int32_t xpos, int32_t ypos, int32_t dx, int32_t dy) const {int32_t intersectionX; Int32_t intersections; If ((dx> 0 & amp; amp; and & amp; xpos> rights) || (dx gt; Top) || (D & LT; 0 & amp; AOPO & Lt; BOT)) Return; If (DX! = 0) {intersection Y = ypos + (left...
