Visual Basic 中的运算符优先级 运算符(按功能列出) 运算符(按功能列出) & 运算符 (Visual Basic) &= 运算符 (Visual Basic) * 运算符 (Visual Basic) *= 运算符 (Visual Basic) + 运算符 (Visual Basic) += 运算符 (Visual Basic) = 运算符 (Visual Basic) - 运算符 (Visual Basic) -= 运算符...
如果操作数由一个 Boolean 表达式和一个数值表达式组成,则 Visual Basic 会将 Boolean 表达式转换为数值(–1 表示 True,0 表示 False)并执行位运算。 对于Boolean 比较,结果的数据类型为 Boolean。 对于位比较,结果数据类型是适用于数据类型 expression1 和expression2 的数值类型。 请参阅运算符结果的数据类型中的...
如果文件包含 Visual Basic for Applications (VBA) 工程(例如,启用宏的 Excel 文件),则信任中心会因该文件可能包含宏而应用更多限制。 仅当您确信 ActiveX 控件和其他活动内容的来源可靠时,才启用它们。 返回页首 在Word、Access、Excel、PowerPoint、Publisher 和 Visio 中更改 ActiveX 控件设置 若要...
The pattern of calling an asynchronous method that we show here is the simplest one to use when you call asynchronous APIs in an event handler. You can also use this pattern when you call an asynchronous method in an overridden method that returnsvoidor aSubin Visual Basic. ...
Since the logical and bitwise operators have a lower precedence than other arithmetic and relational operators, any bitwise operations should be enclosed in parentheses to ensure accurate execution. Data Types If the operands consist of oneBooleanexpression and one numeric expression, Visual Basic convert...
