  5. VBA kennt die Parameterübergaben ByRef (Übergabe der Referenz auf die Speicherstelle mit dem Wert der Variablen) und ByVal (Übergabe des Wertes der Variablen). Im ersten Fall - das ist die Standardeinstellung, d.h. wenn keine Vorgabe erfolgt, wird der Parameter als ByRef behandelt - wird der Wert des Parameters weiterverarbeitet; Änderungen.
  6. VBA kennt die Parameterübergaben ByRef und ByVal. Im ersten Fall - das ist die Standardeinstellung, d.h. wenn keine Vorgabe erfolgt, wird der Parameter als ByRef behandelt - wird der Wert des Parameters weiterverarbeitet; Änderungen sind auch für das aufrufende Programm wirksam

The ByRef and ByVal modifiers are part of a procedure's signature and indicate how an argument is passed to a procedure. In VBA a parameter is passed ByRef unless specified otherwise (i.e. ByRef is implicit if absent).. Note In many other programming languages (including VB.NET), parameters are implicitly passed by value if no modifier is specified: consider specifying ByRef modifiers. ByVal Example: This is a ByVal Example. Sub X(ByVal a As Variant) a = 20 Debug.Print in sub X value of a = & a End Sub Sub Y() a = 10 Call X(a) Debug.Print in sub Y value of a = & a End Sub. Both examples are same with the only difference of argument passing. Here in X, arguments are declared as ByVal

ByVal的意思是按值传递,是指在程序中调用过程时,带实参值的调用语句知识将实参变量复制给过程中的形参,即将实参变量的副本传递给过程中的形参。. 1、参数的数据类型:. 过程的参数被缺省为具有 Variant 数据类型。. 也可以声明参数为其它数据类型.

Difference between ByRef ByVal in Access Excel VBA. ByRef means to pass a variable or Object by Reference (memory address). ByVal means to pass a variable or Object by Value.

However, when you pass your typed array (say, array of bytes) to a function that is expecting a ByVal Variant as an argument, VBA doesn't interpret it as an array of Variants, but simply a Variant type variable that contains a byte array. The only additional cost involved is the time it will take to resolve the Variant 64 bit: The first argument -hWnd- is a window handle, which is an address in memory. The return value is a pointer to a function, which is also an address in memory. Both of these must be declared LongPtr in 64-bit VBA. The argument wMsg is used to pass data, so can be Long in both 32-bit and 64-bit
