    How to use that array? Vba throws compile error

    • @vitoshacademy
      @vitoshacademy 7 дней назад

      Hello, and thank you for your question.😊 If you are using the code from the article, then try these steps to avoid the compiling error: 1. Delete `Option Explicit ` 2. Make sure that you are having a worksheet named `Sheet1` 3. Put the code in a module. I am away from the keyboard right now, but if the compiling error still exists, try asking in Stackoverflow.com about it, if you tag the question with #Excel and #vba, and provide the code, and explain where is the compiling error, someone will probably answer in less than 1 hour. The #vba community there is helpful. Enjoy your day😊

    Thanks for covering this topic. As I see, there is no such fast solution for Array to range as it is for from range to Array....

    • @vitoshacademy
      @vitoshacademy 4 месяца назад

      🙂In general, I am not the ultimate "knowledge tank" of VBA, there could be a few solutions I am not aware of, but in theory you can easily build a `Sub` that gets an array and based of its dimensions it puts it into a range. Anyway, there are a few decisions you should make - if it is 1D array, how are you going to paste it? (As a column or as a row) What would you do with 3D arrays? Return error, or just write the first 2 dimensions and forget about the rest?

  • @b99eu
    @b99eu 4 месяца назад

    Thanks for the video! One issue - range to array is clear. But array to range is tricky. As long as no row or column is hidden, it works fine. But if there is something hidden (eg due to a filter) it does not work as expected. Any workarounds here?

    • @vitoshacademy
      @vitoshacademy 4 месяца назад

      Thanks for the question! Actually, I have thought of some possible solution for that problem and it might be a working one, if the array is a smaller one. If it is big, then it probably will work as well, but more time would be needed for the loop. I have made a video here, for the solution - - ruclips.net/video/9zzY7qLu92U/видео.html. Enjoy it!
