Hi, how to make a cell formula to only beep once in excel?
In excel, I have used vba's beep function to use that in cells. Now, the cell value changes incrementally (the cell value may incrementally increase or decrease). The incremental value is +/- 100 only. For eg., if the cell value is 1200 from the data feed, it positively increments either to 1300, 1400, 1500, etc., or negatively increments to 1100, 1000, etc. I am only concerned about "A" particular cell in an excel sheet because the data feed happens only in ONE particular cell.
For every increment, I have used the VBA beep function to alert me.
Whenever the beep happens, I have to manually change the formula (=if(D5<>1500,beepnow,"") to the increment that just had happened. Else, it keeps on beeping.
What I require is, the formula should automatically beep once - that's all! Then, the beep should happen only when there is incremental "change" in the cell D5. Otherwise, the beep shouldn't happen. The data feed happens during most part of the day, but I wouldn't know when it would happen; hence this beep alert is a kind of helping me instead of sitting always in front of the system waiting.....
Can it be done with a formula or can it be done via VBA? Kindly, help me on this. Thank you! Prabhu Sample.xlsm
I would use a static variable in your beepNow function:
