Hello, is there a way to make the user unable to type text and have the default item selected as 0 or would i have to use a different component?

[@dani-wi1ot]

Pls I have a text file and I want some values on the text files to be shown on combobox ..any tips?

[@MrLongITandCAT]

Loop through the text file and add the values to the combobox. var myfile: textfile ; sLine : string ; Begin AssignFile( myfile , 'textfile_name.txt' ) ; Reset( myfile ) ; while NOT eof( myfile ) do begin readln( myfile, sLine ) ; combobox1.Items.Add( sLine ) ; end; CloseFile( myfile ) ;

Hello. Thank you very much for the detailed explanation. But there is a problem that once selected the item is not reset and the last one remains selected. To overcome this problem cmbx.itemindexI=-1; cmbx.text:='Please select..'; But that's more lines of code. How to write more concisely?

[@MrLongITandCAT]

Not sure what you are asking. You can check to see if an item is selected by using an if statement: if cmbx.ItemIndex = -1 then showmessage('Please select') else begin //do code here for selected item

Hello , I have a question for my pat. I want to use the data from a combobox on Form1 on another combobox in Form2. Can someone please help me?

[@MrLongITandCAT]

At the top of form2 you must add the file name of form1 (Unit1 or whatever its name is) under uses. Then you should be able to type sValue := Form1.comboxbox1.value If that doesnt work then try then name of the unit file of form 1 sValue := Unit1.comboxbox1.value
