Declare an integer variable
Use an assign activity to increment the value inside the for loop.

Variable = variable+1

Where do i get the for loop from. There is only a for each loop. In this case, I am not using an array. So how do I do that. Or how do I set an array to size of 10?

If you just want to loop up until a condition - use a Do While or While loop

For a Do While - Your condition will be intCounter < 10
and increment your counter at the end of your sequence.

@bobby,

You can declare an array and in the variables panel you can initialize it default/known size of the array.

 New String(10) {}

In case of you are using a for each activity:

A bultin feature is doing this for you:

Output

  • Index - A zero-based index that specifies which element of the current collection is being iterated, stored in an Int32 variable.

But maybe you are in process of a different scenario. So just tell us more about it

I tried that and it did not work. The count does not increament. I basically added a do while activity. Outside created an assign with count =0. Inside the do while activity. I placed the activity I want it to process and then after increament the count by doing count = count +1. In the condition I did do this until count = 10. I printed the count and it appears blank

Ah that’s cool. I did not know that was there. I will try that. Thanks. :slight_smile:

so your sequence should look like this:

Assign Counter (int) = 0
Do While Counter < 10
   Log Message = Counter.Tostring
   Assign Counter = Counter + 1

Hey TimK, that works. The thing I did wrong was made the count =10, not less than 10. Why is equal to 10 not right? Sorry, I am confused.

both are correct it depends on what you want the loop to do :slight_smile:

the operator < is required to make the condition true once it reaches 10, = will not work because you are looping only while counter is = 10 (which it doesnt so will exit)

So the first time you loop - your counter will = 1 as you have incremented it so the condition is false and breaks the loop.

Hope thats helps :slight_smile:
