A Boolean indicating if the code is to break when an expression changes. true indicates that the package is to break; false indicates that the package will not break.

Примеры

The following code example retrieves the breakpoint target collection from the package and iterates through the breakpoints, displaying the properties for each breakpoint, including the BreakOnExpressionChange.

Sample Output:

BreakOnExpressionChange? False

Description Break when the container receives the OnPreExecute event

Enabled? False

HitCount 0

HitTarget 0

HitTest Always
