Hey, I can't figure what is wrong with this part of my program. I know that it has something to do with that my variable i is exceeding the vector boundaries but I can't figure out how to stop it. I try to make the program exit before the vector goes beyond it's boundaries, but it's just not working for some reason. Here's the code:

int i = 0;
int numright = 0;
int rw = 0;
vector<string> wrong;
BOOL CALLBACK DlgProcqw2(HWND hwndqw2, UINT Messageqw2,WPARAM wParamqw2, LPARAM lParamqw2)
{
	string word = rEngV[i];
	HWND handle = GetDlgItem(hwndqw2, IDC_VIEW);
	SetWindowText(handle, word.c_str());
	switch(Messageqw2)
	{
		case WM_INITDIALOG:
			{
			g_hbmB = LoadBitmap(GetModuleHandle(NULL), MAKEINTRESOURCE(IDB_B));
			g_hbmR = LoadBitmap(GetModuleHandle(NULL), MAKEINTRESOURCE(IDB_R));
			g_hbmW = LoadBitmap(GetModuleHandle(NULL), MAKEINTRESOURCE(IDB_W));
			if(g_hbmR == NULL || g_hbmW == NULL)
				MessageBox(hwndqw2, "Could not load IDB_R or IDB_W!", "Error", MB_OK |MB_ICONEXCLAMATION);
			}
		case WM_PAINT:
		{
			BITMAP bm;
			PAINTSTRUCT ps;
			if(rw == 0)
			{
				HDC hdc = BeginPaint(hwndqw2, &ps);

				HDC hdcMem = CreateCompatibleDC(hdc);
				HBITMAP hbmOld = (HBITMAP)SelectObject (hdcMem, g_hbmB);

				GetObject(g_hbmB, sizeof(bm), &bm);

				BitBlt(hdc, 34, 90, bm.bmWidth, bm.bmHeight, hdcMem, 0, 0, SRCCOPY);

				SelectObject(hdcMem, hbmOld);
				DeleteDC(hdcMem);

				EndPaint(hwndqw2, &ps);
			}
			if(rw == 1)
			{
				HDC hdc = BeginPaint(hwndqw2, &ps);

				HDC hdcMem = CreateCompatibleDC(hdc);
				HBITMAP hbmOld = (HBITMAP)SelectObject (hdcMem, g_hbmR);

				GetObject(g_hbmR, sizeof(bm), &bm);

				BitBlt(hdc, 34, 90, bm.bmWidth, bm.bmHeight, hdcMem, 0, 0, SRCCOPY);

				SelectObject(hdcMem, hbmOld);
				DeleteDC(hdcMem);

				EndPaint(hwndqw2, &ps);
			}
			if(rw == 2)
			{
				HDC hdc = BeginPaint(hwndqw2, &ps);

				HDC hdcMem = CreateCompatibleDC(hdc);
				HBITMAP hbmOld = (HBITMAP)SelectObject (hdcMem, g_hbmW);

				GetObject(g_hbmW, sizeof(bm), &bm);

				BitBlt(hdc, 34, 90, bm.bmWidth, bm.bmHeight, hdcMem, 0, 0, SRCCOPY);

				SelectObject(hdcMem, hbmOld);
				DeleteDC(hdcMem);

				EndPaint(hwndqw2, &ps);
			}
		}
		break;
	case WM_COMMAND:
		switch(LOWORD(wParamqw2))
		{
			case IDC_OKQW:
				{
					char text[255] = {0};
					GetDlgItemText(hwndqw2, IDC_ANSQW, text, sizeof(text));
					string span = text;
					string span2 = rSpnV[i];
					if(span == span2)
					{
						rw = 1;
						++numright;
					}
					else
					{					
						rw = 2;
						wrong.push_back(word);
					}
					if (i == rEngV.size())
					{
						EndDialog(hwndqw2, 0);
						hwndGotoqw2 = NULL;
					}
					else
					++i;
					InvalidateRect(hwndqw2, NULL, true);
				}
			break;
		}
	break;

change "if (i == rEngV.size())"
to "if (i == rEngV.size() - 1)"

accessing rEngV[rEngV.size()] is wrong
