用MFC实现代码获取当前EXE 执行的绝对路径，用于扩展相对路径扩展，以及计算文件大小功能

(1) calc_size.c source code

#include <stdio.h>

#include <windows.h>

#include <string.h>

int main(int argc, char** argv)

{

int size = 0, len;

FILE * fp = NULL;

char BufferFileName[MAX_PATH];

char *str_buf = NULL;

if (argc <=1)

{

printf("usage: cmd file .");

return -1;

}

GetModuleFileName(NULL,BufferFileName,MAX_PATH);

printf("file path: %s \n", BufferFileName);

len = strlen(BufferFileName);

printf("len = %d ", len);

str_buf = (BufferFileName + len - 13);//这里calc_size.exe

strcpy(str_buf, argv[1]);

printf("argv[1] = %s, file_path_argv[1] = %s ", argv[1], BufferFileName);

fp = fopen(BufferFileName, "r");

fseek(fp, 0L, SEEK_END);

size = ftell(fp);

fclose(fp);

printf("size = %d", size);

return size;

}

(2) 文件树结构：

D: - - - AUTOTEST - - - FPGA.bat

|

- - - - - - - - FPGA - - - - - T32 - - - -- - calc_size.exe

|

- - - - - - -- load_image_cmm - - - - hello.raw

(3) FPGA.bat code

echo off

set path=%path%;d:\AUTOTEST\FPGA\t32

calc_size.exe load_image_cmm\hello.raw

pause

放到其他E:盘等同理。
