Jun 23, 2015 Re: Mac VBA Solver -- only solves last of three commands Finally, an answer!! I spent far too much time trying to use a macro to loop the solver in the mac version of excel and display the solutions in a series of cells, and all it would ever do is post the same number (present at the beginning from a previous solution) in all the output cells. Solver is a Microsoft Excel add-in program you can use for what-if analysis. Value for a formula in one cell — called the objective cell — subject to constraints, or limits, on the values of other formula cells on a worksheet. Windows macOS. There was a brief explanation in the previous article, but nothing dedicated to how to implement it from start to finish. In this article we’ll go in depth from start to finish covering the concepts and methods step by step. By the end you’ll be able to automate any of your own personal models and scale your analysis. To get the most out of this article you should be familiar with the basics of Excel Solver. If you need to brush up check out this comprehensive whitepaper,. How we’ll do it We’ll leverage the to handle most of the actual code. The record macro tool will allow Excel to convert our manual steps into VBA code. We will then identify the key pieces of code to change. Then we will create a loop to dynamically select and replace these values and run the solver again. This will be semi-technical but through this style of development we can focus on the process and the concepts instead of focusing on how to write code. Setting up the macro recorder The macro record functionality is found in the developer tab in the ribbon. This is not available by default but is easy to implement. If you navigate to your ribbon options you will see a checkbox for the developer tab. The screenshot below is for Mac but PC based Excel is similar. If you have not installed the solver add-on you can install it via the Add-ins menu. The Microsoft support site has instructions for all platforms,. Recording the macro Now that the set up is complete we we are ready to record! Set up your workspace appropriately with all your formulas and references. You’ll want to set up everything to the point before you build the solver model. Make your way back to the developer tab on the ribbon. You will see a piece of paper with a red dot. Click on that button to open the recorder. Give your macro a name and fill in the description if you’d like. ![]() Once you hit OK the recorder will begin. Go through the steps of setting up your solver and solve it. Once this is complete go back to the developer tab and stop recording. It’ll be the same location as the button you used to start the recording. Now that we have the base code we can clean it up and prep it for the next steps. Clean up the code Now we can edit the code, remove any unnecessary parts, and make sure we are only using the essential pieces of the macro recording. You can edit the code through Excel’s VBA editor. To access your recorded code click the Macros button. Navigate to your macro in the new menu and click edit. Now that we have our code editor open we can start making tweaks. Removing Unnecessary Code If you happened to click through a bunch of other things while recording you can clear those out now and be left with something similar to below. If there is a lot of extra code and you are worried about breaking it, you can always rerecord. Setting up the solver references One last step before we move on, go to Tools > References and select Solver. If you don’t do this the package will not load in the macro and you’ll get an error. You can now change your parameters open the macros menu, select your macro, hit run and it will update the results. Performance Battery & Performance Saver We designed Bitdefender to give you the most effective protection, combined with effective power management. Receive an alert when you step too far away from your phone, so you never leave it behind. Let’s line up the code against our solver model. You’ll see how it lines up. The language is different but you can piece together what it all means. Next we’ll isolate the parts we need to change and wrap up our automation. Rinse and repeat – building the loop Now that we have a working solver. We need to repeat that multiple times. Let’s put an example together and cement the plan. We started with a budget of $1,000 in the first model but we want to do the same thing for $100 increments up to $2,500. Let’s dive in! We have a list of values in column B and our output in column C. If we wrote out the process it would look like, • Set total spend to the value in B10. • Solve the model. • Place the output in C10. So I just use whatever fast local SSD storage the OS is available natively, and make regular copies to the slower 'cross-platform' storage - or only when the project is done, depending on the specific use case. I'm almost always running a Linux VM for 'native' ZFS or BTRFS volume access via CIFS, when not running it natively. Tip: If you do go the VM route, you'll be tempted to share the VM file system via a bridged adapter. I've seamlessly adjusted most of my workflows to accommodate the slower CIFS access to large 'cross-platform' reliable storage. For example, if I need fast access to lots of working data, it's usually in an application that is unique to that particular host OS, and it doesn't need to be accessible across platforms. File system for windows on mac. After creating the bootable installer, follow these steps to use it. Connect the bootable installer to a compatible Mac. Use Startup Manager or Startup Disk preferences to select the bootable installer as the startup disk, then start up from it. Your Mac will start up to macOS Recovery. How to make a bootable OS X 10.11 El Capitan installer drive A bootable installer drive is much more convenient when you're upgrading a Mac. How to create bootable usb for mac os x el capitan dmg file. If you have already installed OS X El Capitan, and wish to now create a bootable installer, you can force the Mac App Store to re-download the installer. The El Capitan installer is downloaded to the /Applications folder, with the file name Install OS X El Capitan. • Choose next B value. • Set the output in the C row. • Repeat steps 2-5 for all values in B. Starting the loop Loops are coding constructs that repeat an action until hitting a logical end point. A loop will come in handy here to repeat the same process, running the solver, on every value until we reach the end of the value. For this example we’ll define the end point by the number of rows.
