The result is that after you double-click a cell to modify it, the data must be updated to the database in a timely manner, and the updated data must be re-bound to the control. However, an error will be reported when the data is re-bound, error

The solution is as follows: (1) convert the Written string into ANSI Char * pbuffer = NULL; long lbuffersize; lbuffersize = widechartomultibyte (cp_acp, wc_no_best_fit_chars, m_srtf,-1, null, 0, null, null ); pbuffer = new char [lbuffersize + 1];

I don't know what the data for this question is. I handed it in two methods. The first direct recursion, the second memory pruning, and the time turned out to be the same !? Directly depressed, simple binary represents the State and binary

The two strings S1 and S2 are given several queries. Query operation: 1 a B c: replace character B of character a with character C 2. A queries the number of S1 [k] = S2 [k] starting from the character. For example, aaa aab queries 2 0 and the
