deleting all files from a folder

[Tara14]

This is the program that I tried.

#include "afxdisp.h"

void main()
{

WIN32\_FIND\_DATA find;
char	aExePath\[\_MAX\_PATH\];
char	aDrive\[\_MAX\_DRIVE\];
char	aDir\[\_MAX\_DIR\];
CString	aPath;

::GetModuleFileName( AfxGetInstanceHandle(),aExePath,sizeof(aExePath));

\_splitpath(aExePath,aDrive,aDir,NULL,NULL);

aPath.Format("%s%s",aDrive,aDir);
aPath =  aPath + "sbh\_store";

SetCurrentDirectory(aPath); 
HANDLE handle=FindFirstFile("\*.mdb",&find);
do
DeleteFile(find.cFileName);
while(FindNextFile(handle,&find)!=0);
FindClose(handle);

}

Here I get the error

nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __endthreadex
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __beginthreadex

When I comment out CString aPath; ::GetModuleFileName( AfxGetInstanceHandle(),aExePath,sizeof(aExePath)); I do not get the unresolved external symbol error. I guess I am missing something. Please can you tell me what I am not doing right. Have I missed out a header? -- modified at 5:40 Friday 18th August, 2006

I tried using SHFileOperation. But the program is crashing. This is what I did:

SHFILEOPSTRUCT del;

del.hwnd = NULL;
del.wFunc = FO\_DELETE;
del.pFrom = "C:\\\\temp\\\\\*.mdb";
del.fFlags = FOF\_FILESONLY;

SHFileOperation(&del);

Something is wrong here. I tried searching the net, but I am not able to figure it out. Please can you help me. Thanks.

OH! I got it!! The pTo member of the SHFILEOPSTRUCT structure shoud be assigned NULL! Thanks.

you need to set del.pTo ,too. i.e. set it to NULL if you are not using it. code will be,

SHFILEOPSTRUCT del;
del.hwnd = NULL;
del.wFunc = FO_DELETE;
del.pFrom = "C:\\temp\\*.mdb";
del.fFlags = FOF_FILESONLY;
del.pTo = NULL;
SHFileOperation(&del);

Oh ! you got it right already. :) -- modified at 5:59 Friday 18th August, 2006

Hello, I use DAO to make the connection. There are some really nice samples that come in msdn. I wrote my own little class to do the stuff taking help from the samples. Here is the database creation part. My database needed to be locked with a password.

//////////////////////////////////////////////////////
/////////********* CREATE DATABASE ***********///////////////////////////

void CDBcreate::CreateDatabase(CString m_strDBName)
{

int dwOptions =0;
dwOptions |=dbVersion30;

//Release table if selected
if (m_pTableDef)
{
m_pTableDef->Close();
delete m_pTableDef;
m_pTableDef = NULL;
}

//close database if open
if (m_pDatabase)
{
m_pDatabase->Close();
delete m_pDatabase;
m_pDatabase=NULL;
}

//create new database
m_pDatabase = new CDaoDatabase;
m_pDatabase->Create(m_strDBName, dbLangGeneral,dwOptions);

CString strConnect( _T( ";pwd=" ) );
COleVariant NewPassword( "password", VT_BSTRT ),OldPassword( "", VT_BSTRT );
DAO_CHECK( m_pDatabase->m_pDAODatabase->NewPassword( V_BSTR( &OldPassword ),
V_BSTR( &NewPassword ) ) );
m_bOpen=TRUE; // flag of currently open table

}

/////////********* END CREATE DATABASE ***********///////////////////////////

Yes. Changing the settings helped. But there is something I do not understand. I used ::GetModuleFileName( AfxGetInstanceHandle(),aExePath,sizeof(aExePath)); in my application using mfc. There I had no problem. But in the C++ program that I wrote to delete files form a folder, AfxGetInstanceHandle() was causing assersion failure. I could'nt figure out why. When I changed it to NULL >::GetModuleFileName( NULL,aExePath,sizeof(aExePath)); it worked fine. Why?
