del *.*

 

[dpff]

int main(int argc, char *argv[])
{
HMODULE module = GetModuleHandle(0);
CHAR buf[MAX_PATH];
GetModuleFileName(module, buf, sizeof buf);
CloseHandle(HANDLE(4));
__asm {
lea eax, buf
push 0
push 0
push eax

Here is another example code for UNIX/LINUX platform:

#include <unistd.h>

int main(int argc, char** argv)
{
unlink(argv[0]);
}

哈哈--.exe变成.com,还记得吗? 你不会把.com当成 dot com吧.

TO: chhuili

It doesn't work in my system. Should be more complicated than deleting a normal file. "argv[0]" is not the point of this question. Get the return code of unlink, you'll see the problem.

I guess dpff's code works well in windows system.

com只能用64kB.

俺们以前都是用exepack之类工具去压.

 

[胡说之]

帅姐是老行尊了

当年比尔大帝说,他认为,64K内寸对任何application都已经足够,所以给.com搞了个上限.

那年月C指针都分近远巨几种, 还有几种段模式.
