如何刪除??

Question

我想刪除一程序路徑如下:
extractfilename(application.exename)+'mysoft.exe';
請問問號處如何寫??
winexec('command.com / c del ????',sw_normal);

Answer 1

str:=extractfilename(application.exename)+'mysoft.exe';
winexec('command.com / c del'+ str,sw_normal);

Answer 2

DeleteFile(Pchar(ExtractFileName(Application.ExeName)+'mysoft.exe'))

Answer 3

我用你的方法,但編譯時出現:
incompatiable types :'string' and 'pchar';
改寫
winexec('command.com / c del'+ pchar(str),sw_normal)也一樣.
請問如何解決??
delefile可行,但仍想弄清以上問題,煩指教.
(不好意思,應該是extractfilepath......)

Answer 4

winexec(PChar('command.com / c del'+ str),sw_normal);
强制类型转化!
为什么不用DeleteFile呢，而用Dos命令呢？
