how to get ComboBox items count

I'm trying to get an combobox items count using the following code. It doesn't give an error nor the the right amount of count. I guess I have to convert int to string, but how?

ComboBox1->ItemIndex = 1;
int count = ComboBox1->Items->Count;
Edit1->Text =  "Count: " + count;
Solution

  • This line

     int count = ComboBox1->Items->Count;

    returns the numnber of string items in your TComboBox. You need to check this before setting 

    ComboBox1->ItemIndex = 1;

    as ItemIndex is used to set the selected item in the combo box and is zero counted. To convert the integer to string in Embarcadero you can use IntToStr() function

    Edit1->Text = "Count:" + IntToStr(count)

    You will need #include "System.hpp" to access that function
