Delete a line in a text file that starts with "//" in a C + + program

VC + + only provides the deletion of an empty directory function, and often want to delete under its many subdirectories and files directory. To achieve this, the DeleteDirectory function is written below, which enables this functionality.

Function prototype: BOOL deletedirectory (char *dirname);

Return value: Returns True when successfully deleted, otherwise returns false

Parameter dirname is the name of the directory to be deleted, and must be an absolute pathname, such as "c:\\temp".

The function is defined as follows:

BOOL DeleteDirectory(char *DirName)
{
CFileFind tempFind;
char tempFileFind[200];
sprintf(tempFileFind,"%s\\*.*",DirName);
BOOL IsFinded=(BOOL)tempFind.FindFile(tempFileFind);
while(IsFinded)
{
IsFinded=(BOOL)tempFind.FindNextFile();
if(!tempFind.IsDots())
{
char foundFileName[200];
strcpy(foundFileName,tempFind.GetFileName().GetBuffer(200));
if(tempFind.IsDirectory())
{
char tempDir[200];
sprintf(tempDir,"%s\\%s",DirName,foundFileName);
DeleteDirectory(tempDir);
}
else
{
char tempFileName[200];
sprintf(tempFileName,"%s\\%s",DirName,foundFileName);
DeleteFile(tempFileName);
}
}
}
tempFind.Close();
if(!RemovwDirctory(DirName))
{
MessageBox(0,"删除目录失败！","警告信息",MK_OK);
return FALSE;
}
return TRUE;
}
