Does anyone know what this code is doing?

Does anyone know what this code is doing?

Hi guys.

I am pmmd861, I am new here. Nice to meet you all!

Could anyone help me with this VBA Excel code, please?

So, i ve got the excel spreadsheet from someone else, and i need to nuderstand the code there so that i could slightly rebuild it in the future. But there is some piece of code that i ve never seen and i have no idea how it works!

Here is the extract from the program.

In the Calibrate sub i have the code



Sheets("EL 1").Select
    ActiveCell.FormulaR1C1 = "1"

This bit is simple.

But when


ActiveCell.FormulaR1C1 = "1"

is executed the code changes the value in the cell H9 AND after that CALLS the user defined FUNCTION in another module! My question is WHY? This is not how you call the function, right? Does it have something to do with windows programming language (i think it called API functions)?

Also, it repeats the function many times, as if it is driven by some external loop (but there is no any cpde the loop).

I tried to delete ALL the code in ALL modules and just to leave this bit - it still call the function in the same way.

Also, there is the same code for another sheet, but on that sheet when one cell is changes it calls the functuion and when another cell is changed it does NOT call this function? PLease, give me a hint where to look for the answer! I searched for Application. properties in the code and in the ThisWorkbook module and didnt find anything! Also, there no any classes in this project.

Does this behaviour resemble something that you know?

Thanx for your help guys!


RE: Does anyone know what this code is doing?

Would imagine that the other function is called because the worksheet is being re-calculated

that would be why it is called a number of times - probably for each cell that it is dependant on...

We could learn a lot from crayons. Some are sharp, some are pretty and some are dull. Some have weird names and all are different colours but they all live in the same box.

xlbo, thanx a lot mate!

Exactly, user defined functions in other cells in another sheet! You were right, so simple!

This workbook has 20 sheets and when i got more details about how it works i ve found a row of cells whith the functions which were dependant on the cells that i change.

Thank you guys for your replies.

Best wishes,
