to a unique integer (0-255). chr (num) converts the number of ASCII values into ASCII characters, which can only be 0Ord accepts an ASCII or Unicode character (a string of length 1) and returns the corresponding ASCII or Unicode value. UNICHR (NUM) accepts Unicode code values and returns their corresponding Unicode characters. The range of code values accepted depends on whether your Python is built on ucs‐2 or ucs‐4. >>> Ord (' a ') the>>> Ord (' A ') $>>> Ord (' 0 ') -string built-in function

Recently in the C # to help the company to do an image recognition function, the use of third-party DLLs, in the process of invoking the DLL, there is a problem. Entrypointnotfoundexception exception. If you encounter this kind of exception, it is very likely that when you generate the DLL, the function output declaration isextern "C + +" _declspec (dllexport) int Add (int param1, int param2), because when using extern "C + +" The compiler will compile this function according to C + + rules, sin

1 Basic explanation : extern can be placed before a variable or function to indicate the definition of a variable or function in another file, prompting the compiler to find its definition in other modules when encountering this variable and function. Also extern can be used for link designation. That is, the extern has two functions, the first, when it is in conjunction with "C", such as: extern "C" void fun (int a, int b); then tell the compiler to

reversed to see if update is selected Hibernate configuration. If you do not check it yourself, next, you can set the ID growth method per table (assigned for the designation, in order to facilitate the system to make the decision ), and the resulting mapping file name considerations: the Class Name to specify the full package name assigned represents dignitaries for designation, in order to facilitate can
