well I was only allocating 11 for it cause it's 2 bytes and the password is only 20 chars long of 1 byte. for some reason if I make the wppasswrd anything other than 11 or 12 I get extra blank characters printed on screen with my password generated.

void SerialGen(){ 	char alpha[80] ="ABCDEFGHIJKLMNOPQRSTUVWXYZ123456789";	char* ppasswrd = NULL;	wchar_t* wppasswrd = new wchar_t[21];	char passwrd[80]="";			int numChars = 20;		for (int n=0; n<numChars; n++)	{		int x;		x = 0 + int(35.0 * rand()/(RAND_MAX+1.0));		passwrd[n]= alpha[x];	}		ppasswrd = passwrd;	memset(wppasswrd,0,sizeof(wppasswrd));	MultiByteToWideChar(  CP_ACP, NULL,ppasswrd, -1, wppasswrd,numChars );	AddString(wppasswrd); // this is the line that causes an exception	getchar();         // whoa! and the following will leak memory//	wppasswrd = NULL;//	delete[] wppasswrd;//      do this instead	delete[] wppasswrd;	wppasswrd = NULL;}

I set the length to 21 and I tried using zeromemory and memset but it prints the password with this after it when running from VC8 |||||||| and ||| when running from the folder. And I don't think I can use delete[] on it cause it clears the password. I don't know where I can deallocate it unless I make it global. maybe I could return it and then delete it outside the function? When it's 21 I don't get that exception though.

wait if DisplayString in my struct = StringToAdd and wppasswrd is getting passed to AddString isn't it already getting deleted when I delete my struct?

// delete FirstString calls...STRINGSTRUCT::~STRINGSTRUCT(){// you have to iterate through your linked list, and delete// all "DisplayString" like this// delete[] Next->DisplayString;// THEN You have to iterate through, deleting all "Next"... which might// blow the stack, if your linked list is very long (delete Next; would// recursively call the destructor STRINGSTRUCT::~STRINGSTRUCT())}
