Saya tahu sedikit tentang pemrograman dan jawaban saya tidak elegan. Sebagai insinyur masa depan saya membutuhkan fungsi di Excel yang bisa menampilkan kepada saya formula. Masalah yang saya temukan dalam solusi Indrek adalah fungsinya mengembalikan kepada saya rumus seperti ini: "C9 * C9 * pi ()" dan saya ingin nama sel di tampilan rumus (C9) diubah menjadi nilai-nilai sel-sel itu; dan itu akan secara otomatis berubah setiap kali angka-angka itu diubah dalam sel C9 asli.
Semacam kode saya berfungsi dengan formula yang sangat dasar. Saya tidak pernah menemukan sesuatu seperti ini di tempat lain, Mungkin membantu seseorang atau tidak. Seseorang mungkin dapat meningkatkan ini ke tingkat yang layak. Seperti yang saya katakan, ini bekerja untuk saya dan saya adalah orang yang praktis dengan sedikit keterampilan dalam pemrograman.
Fungsi pertama bukan milikku sama sekali. Itu diambil dari:
/programming/10951687/how-to-search-for-string-in-an-array
Function IsInArray(ar, item$) As Boolean
Dim delimiter$, list$
' Chr(7) is the ASCII 'Bell' Character.
' It was chosen for being unlikely to be found in a normal array.
delimiter = Chr(7)
' Create a list string containing all the items in the array separated by the delimiter.
list = delimiter & Join(ar, delimiter) & delimiter
IsInArray = InStr(list, delimiter & item & delimiter) > 0
End Function
