: : I try to make a small calculator. : : Their are three editboxes, two editboxes where you put in a number and then you click a button, which makes a caculation edit1+edit2=edit3 and the awnser, edit3, shows up in the third editbox. : : The lay out isn't a problem. My problem is the use of the StrToInt and the reverse fuction. : --------------- : I manged to come so far, but i only can't make the anwser to come in the edit3box. : procedure TForm1.Button1Click(Sender: TObject); : var : getal1: Integer; : getal2: Integer; : begin : getal1 := StrToInt(Edit1.Text); : getal2 := StrToInt(Edit2.Text); : ShowMessage(IntToStr(getal1 + getal2)); : end; -------------- Instead of:
ShowMessage(ResultString); just try:
Edit3.Text := ResultString; In your example this would be:
Edit3.Text := IntToStr(getal1 + getal2); Tip: have a look at DelphiLand's Tutorial, there's even a freely downloadable Dutch version :)
