C++内存泄漏 这段代码导致内存不断增加

Question

struct windowCallback {
	char * childWindowName;//窗口名字
	int winNameSize;//窗口字节数
	HWND hwnd;//窗口句柄
};


HWND getAddWindowHwndByNumber(addWindowInfo addWindowInfo, int size)//获取添加窗口句柄,根据字数
{
	//Sleep(3000);
	USES_CONVERSION;
	windowCallback * winstruct = new windowCallback();

	winstruct->childWindowName = (char *)W2A(addWindowInfo.winName);
	winstruct->winNameSize = addWindowInfo.winNameSize;
	HWND hwnd = findWindow(winstruct);
	HWND hwndParent = GetParent(hwnd);
	LPSTR winNameP = new char[250];
	LPWSTR winNameTemp = new WCHAR[250];
	GetWindowTextA(hwndParent, winNameP, 250);
	GetWindowTextW(hwnd, winNameTemp, 250);

	if (hwndParent != NULL)
	{
		while (hwnd != NULL)
		{
			if (StrCmpA(winNameP, addWindowInfo.parentWindowName) != 0)
			{
				hwnd = FindWindowEx(NULL, hwnd, NULL, winNameTemp);
				hwndParent = GetParent(hwnd);
				GetWindowTextA(hwndParent, winNameP, 250);
			}
			else
				break;
		}
	}
	
	delete winNameTemp;
	delete winNameP;
	delete winstruct;
	return hwnd;
}

Answer 1

前两个delete释放改成delete[]试试

Answer 2

HWND findWindow(windowCallback * winStruct)//查找窗体(前8个字符)
{
    HWND win = GetDesktopWindow();//获取桌面窗口
    EnumChildWindows(win, EnumChildProc, (LPARAM)winStruct);
    win = winStruct->hwnd;
    return win;
}

泄漏就在这几段代码里面。
