如何得到程序的运行目录

[SnakeYangNan]

我最近在写一程序,要求运行时得到自身的目录以便以后的操作
当然是动态的,我肯定不能保证我的程序在任何的机器上目录一样啊
我现在没什么好办法,希望强人指点一下啊

GetModuleFileName获得全路径

[SnakeYangNan]

多谢了

[piaozi2003]

DWORD GetCurrentDirectory(
DWORD nBufferLength, // size of directory buffer
LPTSTR lpBuffer // directory buffer
);

GetModuleFileName得到的是绝对路径加程序名
自己把程序名去掉就是路径了

[freegitago]

VC中可以使用GetMoudleFileName（...）
main函数的第一个参数也是当前可执行程序的目录：
int main(argv, char** argc)
{
cout<<argc[0]<<"\n";
}

给你一段我写的代码，其中有，szCurPath存放的就是路径：

int WriteToLog(int iErrorNumber,TCHAR *szMsg)
{
int i = 0;
int iLastSperate = 0;
TCHAR szCurPath[272];
HANDLE hWndFile;
WIN32_FIND_DATA fileFind;
FILE *fp;
SYSTEMTIME lpSystemTime;

GetModuleFileName(GetModuleHandle(NULL),szCurPath,256);

for (i=0; i<256; i++)
{
if (szCurPath[i] == '\\')
{
iLastSperate = i;
}
else if(szCurPath[i] == '\0')
{
break;
}
}

if (iLastSperate > 0 && i < 256)
{
szCurPath[iLastSperate] = '\0';
}
else
{
return (-1);
}

strcat(szCurPath,"\\MsgTransfer.evt");

//printf("current path: %s \n",szCurPath);

GetLocalTime(&lpSystemTime);

printf("current time: %04d-%02d-%02d %02d:%02d:%02d:%03d\n",
lpSystemTime.wYear,lpSystemTime.wMonth,lpSystemTime.wDay,
lpSystemTime.wHour,lpSystemTime.wMinute,lpSystemTime.wSecond,
lpSystemTime.wMilliseconds);

hWndFile = FindFirstFile(szCurPath,&fileFind);
FindClose(hWndFile);


if (INVALID_HANDLE_VALUE == hWndFile)
{
if ((fp = fopen(szCurPath,"w")) == NULL)
{
return (-2);
}
fprintf(fp,"%04d-%02d-%02d %02d:%02d:%02d:%03d Event:%06d %s\n",
lpSystemTime.wYear,lpSystemTime.wMonth,lpSystemTime.wDay,
lpSystemTime.wHour,lpSystemTime.wMinute,lpSystemTime.wSecond,lpSystemTime.wMilliseconds,
iErrorNumber,szMsg);
fclose(fp);
}
else
{
if (fileFind.nFileSizeLow > 61440) // if event file size > 60K, delete, create new
{
if (DeleteFile(szCurPath))
{
if ((fp = fopen(szCurPath,"w")) == NULL)
{
return (-2);
}
fprintf(fp,"%04d-%02d-%02d %02d:%02d:%02d:%03d Event:%06d %s\n",
lpSystemTime.wYear,lpSystemTime.wMonth,lpSystemTime.wDay,
lpSystemTime.wHour,lpSystemTime.wMinute,lpSystemTime.wSecond,lpSystemTime.wMilliseconds,
iErrorNumber,szMsg);
fclose(fp);
}
}
else
{
if ((fp = fopen(szCurPath,"a+")) == NULL)
{
return (-3);
}
else
{
fprintf(fp,"%04d-%02d-%02d %02d:%02d:%02d:%03d Event:%06d %s\n",
lpSystemTime.wYear,lpSystemTime.wMonth,lpSystemTime.wDay,
lpSystemTime.wHour,lpSystemTime.wMinute,lpSystemTime.wSecond,lpSystemTime.wMilliseconds,
iErrorNumber,szMsg);
fclose(fp);
}
}
}

/***********************************************
if (SetCurrentDirectory(szCurPath) != 0)
{
printf("set current path ok...\n");
}
else
{
printf("set current path failure!\n");
}
***********************************************/

return (1);
}

在 strcat(szCurPath,"\\MsgTransfer.evt"); 之前获取到的就是.
