Re: How to redim an array that represents a field of a structure?

Hi there! I'm willing to redim an array of bytes that is a field of a structure with some other fields. But I can't! Let's say the structure is DiscStruct and I use the following command to redim the field abData[1]: ReDim DiscStruct.abData [20]. But no use! The compiler doesn't return any error but the array's dimension remains unchanged! How come? Can anyone please tell me where am I wrong?

Re: How to redim an array that represents a field of a structure?

Structure has a fixed size that cannot be changed (similar to C++). You can define the structure member/field as a variant type:

structA
{
    vr : variant  ! will hold the array
}

stA: structA
al : long[1]

! initialize as array field with one element
stA.vr=al

! assign a value to the array
stA.vr[0]=120
print  stA.vr[0]

! redim to 100 elements
redim al[100]
al=stA.vr ! preserve the values
stA.vr=al  ! will set the variant to hold 100 elements
