    Arrow Calculating a Block of Formulas

    I have some formulas that are nested in cells A1:F100 that will not calculate with the conventional automatic calculation setting since they are referring to a homemade dll.
    The only way the formulas will calculate is if you re-enter each formula over top of the cell. I am wondering if, programmatically, one could say activecell.value = activecell.value.

    What would be the most efficient way of calculating these formulas?

    I'd be interested in seeing if a single instance of

    1. Make a copy of your workbook and run the following code on your copy (just in case)
    2. With excel open, press ALT+F11 to open the Visual Basic Editor (VBE). From the "Insert" menu, select "Module".
    3. Paste the code from above into the empty white space. Close the VBE.
    4. From the developer tab, choose "Macros", select the Sub Name, and click "Run".

    sometimes adding rand()*0 to the end does the trick. ="your custom formula(a1)"+rand()*0

    Re: Calculating a Block of Formulas

    That's assuming the formulas have a numeric output. For string outputs, this is a slight alteration on Martin's suggestion to make the formula volatile:

    ="your custom formula(a1)"&REPT("",RAND()*0)
    Hope that helps,
