MSFlexGrid1.RemoveItem 1 '删除控件中的本行数据Error en tiempo real 30015
El problema que tengo aquí es que todos los datos en el control deben eliminarse después de que todas las computadoras estén apagadas, pero hay un error en tiempo real 300015
Después de consultar, se encontró que el problema apareció en las propiedades de control de MSFlexGrid.
Solución: haga clic con el botón derecho para seleccionar las propiedades del control, cambie su fila fija y cambie de 1 a 0
Seleccionar para desmontar
La idea es marcar primero el seleccionado, para que al borrar solo se borre la línea marcada
