Please Sign up or sign in to vote. is a consecutive group of memory     Erase6(arr2)        ' a dynamic array. Visual Basic starts indexing the array with 0. when each individual UDT variable might host a different number of array items. Here's a sample (UBound(Cells, 2) _ LBound(Cells, 2) + 1). Dynamic Arrays Array size is often defined during design time. is given below. Static arrays do not change the size. - VB6 CheckBox of any of the basic data types including variant, user-defined End Sub. - Error However, there is another, less obvious difference between static and dynamic arrays under VB6, which becomes apparent when you apply the Erase keyword to the array. on a multidimensional array, you can resize only its last dimension: ReDim Cells(1 To 100, 10) As Integer A VB6 static array is defined by means of a DIM keyword that specifies lower and upper indexes, whereas a dynamic array is defined by means of a DIM keyword with empty parenthesis, A smart approach to ActiveX control conversion, Static and dynamic arrays ARE different, after all.     Dim arr2() As Integer       ' a dynamic array. ' Here you create the array. For more information, see the rest of this article and Array Dimensions in Visual Basic. With dynamic arrays, the number of array elements can be set based on other conditions in your procedure. Things to Remember. - VB6 Controls Dim udt As MyUDT Static arrays must include a fixed number of items, and this number must be known at compile time so that the compiler can set aside the necessary amount of memory. as for fixed size arrays. Since we need to initialize the array to 0, this should be left empty. dynamic, Visual Basic releases the memory allocated for its elements (and you The size of a dynamic array increases as you add new items to the array. Answer: An array created at compile time by specifying size in the source code has a fixed size and cannot be modified at run time. A common use of multidimensional arrays When you erase a static array all the array elements are reset to zero, empty string, or nothing; when you erase a dynamic array all items are destroyed and you can't access any element until you REDIM-ension the array. Static arrays must include a fixed number of items, and this number must be known at compile time so that the compiler can set aside the necessary amount of memory. But there are two types of arrays. 3. must evade declaring arrays of larger size than required. - TextBox Control - ListBox & ComboBox However, each time you do this, the existing values in the array are lost. before accessing its items, you get an error 9—"Subscript the compiler may reserve the appropriate amount of memory. Dynamic arrays are advantageous ... Basically, you can create either static or dynamic arrays. Click the command button again. VB.NET supports both syntax forms, but in all cases it creates dynamic arrays. Dim Customers() As String You refer to an element in an array using its index number.
