VISUAL BASIC FOR EXCEL FOR LOOP CODE

Once again, when the loop is finished, myrow will contain a value of 21. In this case, we test to see if the current cell is empty, and we iterate until that condition is met. The next example is very similar, but the condition is different. After the loop is completed, myrow will have a value of 21, indicating the row number of the first empty row following the table. The loop continues as long as this condition is true, hence the 'While' statement. The condition being tested is whether the current cell is NOT empty. The row counter (myrow) is incremented in the body of the loop. Each time through the loop, the myrow variable indicates the row number of the current row being examined. The objective of the loop is to look at each cell in column A starting at row 4.

This code assumes that we have already declared an integer variable named numneg. The objective of the loop is to count how many negative numbers there are in the range B4:D20. Once all the objects are visited, code execution moves to the next line of code following myitem. Next myitem marks the end of the loop and it increments the myitem alias to reference the next object in the collection. During each loop iteration, myitem becomes an alias for the current object being referenced, so typically you do something with myitem in the statement(s). The way the loop works is that the statement(s) are executed once for each object in the collection. If you are ever in doubt as to what type to use, go ahead and use the Variant type. myitem is a looping variable and vartype is the type corresponding to the individual objects in the collection. In this case, mycollection refers to the collection of objects that we wish to loop through. The syntax is as follows: Dim myitem As vartype This could include the cells in a range, the sheets in a workbook, or the shape objects associated with a particular sheet. For Each.įor each loops are used to loop through a collection of objects. However, in many cases multiple types will work and the choice of while loop to apply becomes a matter of personal preference. There are three basic types of loops in VB:Įach type of loop has certain advantages and is best used in certain circumstances. In this section we will review the various options available in VBA for writing loops and examine several example applications. Or perhaps we need to iterate through a set of numbers in order to perform some kind of numerical calculation that can't be performed with a built-in Excel function.

For example, maybe we need to loop through a column of cells until we find a blank cell. There are many cases in programming where we need to perform some type of iteration.
