Protected override void wndproc (ref message m) { const int wm_syscommand = 0x0112; const int SC _close = 0xf060; If (M. MSG = wm_syscommand & (INT) M. wparam = SC _close) { // Block incoming message events This. windowstate = formwindowstate.

In the programming process, file operations are a common problem. In C ++ builder, you can use multiple methods to operate files, I will introduce this in detail in the following parts: 1. C-based file operations; 2. File Operations Based on C ++;
