下面的示例循环访问多维数组。 在用 Visual Basic 编写的 Windows 控制台应用程序中,将代码粘贴到Sub Main()方法中。 最后一个注释显示输出。 VB Dimnumbers = {{1,2}, {3,4}, {5,6}}' Iterate through the array.Forindex0 =0Tonumbers.GetUpperBound(0)Forindex1 =0Tonumbers.GetUpperBound(1) Debug...
When you iterate through an array, you access each element in the array from the lowest index to the highest or from the highest to the lowest. Typically, use either the For...Next Statement or the For Each...Next Statement to iterate through the elements of an array. When you don't...
array. When you use Visual Basic syntax to define the size of an array, you specify its highest index, not the total number of elements in the array. You can work with the array as a unit, and the ability to iterate its elements frees you from needing to know exactly how many ...

When you iterate through an array, you access each element in the array from the lowest index to the highest index. The following example iterates through a one-dimensional array by using theFor...Next Statement (Visual Basic). TheGetUpperBoundmethod returns the highest value that the index ca...

There are three basic ways you can use Automation: MFC, #import, and C/C++: With MFC, use the Visual C++ ClassWizard to generate "wrapper classes" from the Microsoft Office type libraries. These classes, as well as other MFC classes, such as COleVariant, COleSafeArray, COleException, simpl...
