starting FTP Upload from DLL ?

hey

i made a dll which is saving ur own game progress in a file.

now i also want to upload that file on a ftp server when the dll detaches the process.

is it possible to upload files when the dll is getting detached ?
i made it like this but it seems to dont work (getting the error of FtpPutFile when it fails)

Code:

...
ofstream ofile;
ofstream f;
char dest[9999];
TCHAR NPath[MAX_PATH];
WIN32_FIND_DATA FindFileData;
HINTERNET hOpen, hConnection;

void upload(char *bla);

BOOL WINAPI DllMain ( HMODULE hDll, DWORD dwReason, LPVOID lpReserved )
{
...
...
case DLL_PROCESS_DETACH:

		if(ofile) 
		{ 
			GetCurrentDirectory(MAX_PATH, NPath);
			
			add_log("\n\n[Log Closed]"); 
			ofile.close();
			Sleep(500);

			FindFirstFile("./progress.txt", &FindFileData);
			
			sprintf_s(dest, "%s\\%s", NPath, FindFileData.cFileName);
                        MessageBox(NULL,  dest, "Test", NULL);
			upload(dest);
                        break;
		}
	}
	return TRUE;
}

...
...


void upload(char *filepath)
{


	hOpen = InternetOpen(NULL, INTERNET_OPEN_TYPE_DIRECT, NULL, NULL, 0);

	

	hConnection = InternetConnect(hOpen, "example.bplaced.net", INTERNET_DEFAULT_FTP_PORT,
		"usernameExample", "passwordExample", INTERNET_SERVICE_FTP, NULL, NULL);

	

	if(!(FtpPutFile(hConnection, filepath, "/progress.txt", FTP_TRANSFER_TYPE_BINARY, INTERNET_FLAG_PASSIVE))){

			
		f.open("./Fehler.txt", ios::app);
		f << GetLastError() << endl;
		f.close();
	}else{

		MessageBox(NULL, "Successfully uploaded !", "Ftp Upload", NULL);
	}

	InternetCloseHandle(hConnection);
	InternetCloseHandle(hOpen);
	

}

... => means that there is the other code, didnt want to upload the whole code because it�s a lot of code :p

i hope u can help me :)
