For…Next <\/span> <\/span>Command<\/span><\/span><\/p>\n

Repeats a block of instructions a certain number of times, from to .
\n
For < counter > = < start > To < end > <\/span>
< block of instructions > <\/span>
Next<\/span><\/p>\n

Exercises:<\/span><\/p>\n

1. Create three demo tags.
\n2. Insert a chart on screen.

For Each \u2026 Next Command<\/span><\/span><\/p>\n

A For Each…Next loop is similar to a For…Next loop. Instead of repeating the instructions of a block a specific number of times, a For Each\u2026Next loop repeats a group of commands for each item in a collection. This command is useful when we do not know the quantity of elements.<\/p>\n

For each < object > in < Collection > <\/span>
< block of instructions > <\/span>
Next<\/span><\/p>\n

Examples:<\/p>\n

‘Display the name of all the tags<\/span>
For each tag in Application.GetObject(“Data”)<\/span>
MsgBox tag.Name<\/span>
next<\/span><\/p>\n

Exercises:<\/span><\/span><\/p>\n

\n6. Insert a chart on screen.
\n7. By clicking on an [Add] button, create a pen for each tag.<\/p>\n

While…Wend Command<\/span><\/span><\/p>\n

This command executes a block of instructions while a certain condition is true:<\/p>\n

While < condition > <\/span>
< block of instructions ><\/span>
Wend<\/span>
Examples:<\/p>\n

‘Add 1 while it is less than 10<\/span>
While Tag.Value < 10 <\/span>
Tag.Value = Tag.Value + 1<\/span>
Wend<\/span><\/p>\n

Exercises:<\/span><\/span><\/p>\n

8. Create a horizontal rectangle on screen that woks a progress bar.
