I have this block of python code to plot a city-scale satellite map.

I've used Laravel, where we can define relationships inside the model itself. So is that possible in Dart/Flutter?

I've built this Cart Model where Grand-total should be dynamic. So whenever I create an instance of this Cart Model, grand total will be auto-calculated once we enter the total & discount. until then the default value 0.

code from the image above:

So in flutter I have auto-calculated text fields and I want to calculate a result using a formula.

Let me first show what I am doing:

These are those text fields.

The code for these fields:

So I have auto-calculated text fields in flutter. Here it's code:

I have auto-calculated value boxes in flutter. Here is the code for that:

I have a collection of workorders where it have time_started and time_completed values. I want to have auto-calculated field called duration that automatically calculated time_completed - time_started. What is the best way? Essentially what I want is, when App post requests with a completed time, my duration is auto calculated. Example data

I want an array formula to use with Google Forms data to automatically calculate running metrics on my data.

In this case, in column H, M, R and S I want it to auto-calculate whenever new responses come in. Columns H, M and R are ok except for column S.

I'm trying to use this formula below for the sum of each row in these specific columns H, M and R results in a grand total at the column S but isn't working.

I want an array formula to use with Google Forms data to automatically calculate running metrics on my data.

In this case, in column Q, AE and AS I want it to auto-calculate whenever new responses come in.

I'm trying to use this formula below but isn't working for all column, just for the first line.

Hi stackoverflow community.

I am trying to create an interactive form for my access database, that tries to do as much work as possible for the user inputting the data. We will have to use the form in quick succession with multiple samples so I am trying to automate anything I can.

I have produced the following form at this point, which contains some details about some samples which I will be taking from my upcoming testing.

What I want to add to the form is a calculated sample name in the "Sample Name" field. This would auto-calculate with data from the other fields and then once the user is finished entering data, its value is entered into the database. For an example, if the sample was from ESN "91014" and from the sampling location "01" and sample type "powder" then the sample name would calculate something along the lines of "91-01-pow". This sample name would then be entered into the database along with its other data. Maybe on the click of a button?

I have tried using the control source section on the property sheet to calculate the value but this doesn't contain the excel functions I am familiar with (left, middle, right etc) and I cant figure out how to code this in VBA.

Has anyone got some experience with this that might solve this?

All the best
