All data is loaded from text documents.

Details button code:

if (ListBox2->ItemIndex == -1) {exit;} ListBox2->ItemIndex = 0; if (ListBox2->Items->Strings[ListBox2->ItemIndex] == AnsiString("Васин А.В.")) { Memo3->Lines->Clear(); Memo3->Lines->LoadFromFile("texts/vasin.txt"); } if (ListBox2->Items->Strings[ListBox2->ItemIndex] == AnsiString("Иванов С.И")) { Memo3->Lines->Clear(); Memo3->Lines->LoadFromFile("texts/ivanov.txt"); } if (ListBox2->Items->Strings[ListBox2->ItemIndex] == AnsiString("Петров Д.П.")) { Memo3->Lines->Clear(); Memo3->Lines->LoadFromFile("texts/petrov.txt"); } if (ListBox2->Items->Strings[ListBox2->ItemIndex] == AnsiString("Сидоров В.С.")) { Memo3->Lines->Clear(); Memo3->Lines->LoadFromFile("texts/sidorov.txt"); } if (ListBox2->Items->Strings[ListBox2->ItemIndex] == AnsiString("Степанов А.С.")) { Memo3->Lines->Clear(); Memo3->Lines->LoadFromFile("texts/stepanov.txt"); }

Keep the pointer to the second form in the first, through it will be access to the elements. The pointer must be declared on the base class Form, not Form2
