[RESOLVED] stop items duplicating

I have a project due for college tomorrow,its an IT job finder project..so far I've coded the command buttons,textboxes,checkboxes etc,so anything the user inputs on form1 will be printed off on form 2...

Im stuck on the listbox and combo box ......I have 1 combobox which displays three jobtypes ...Permanent,Full time and Part time,once the user clicks on any of these a listbox with 5 jobtitles should appear in the listbox to the right of the combo box....

VB Code:

Private Sub Cbojobtype_Click()
If Cbojobtype.Text = "Full Time" Then
lstjobtitle1.AddItem "IT Manager"
lstjobtitle1.AddItem "IT Sales Executive"
lstjobtitle1.AddItem "IT Field Technican"
lstjobtitle1.AddItem "IT Procedure Director"
lstjobtitle1.AddItem "IT Director"
 
ElseIf Cbojobtype.Text = "Contract" Then
lstjobtitle1.AddItem "IT Auditor"
lstjobtitle1.AddItem "IT Project Manager"
lstjobtitle1.AddItem "Operations & IT Coordinator"
lstjobtitle1.AddItem "Service & Support Manager"
lstjobtitle1.AddItem "Senior Engineering Manager"
 
 
ElseIf Cbojobtype.Text = "Part Time" Then
lstjobtitle1.AddItem "Ecommerce consultant"
lstjobtitle1.AddItem "Network Engineer"
lstjobtitle1.AddItem "Programmer"
lstjobtitle1.AddItem "Test Analyst"
lstjobtitle1.AddItem "QA Manager"
 
End If
End Sub
 
Private Sub Form_Load()
Cbojobtype.AddItem "Contract"
Cbojobtype.AddItem "Full time"
Cbojobtype.AddItem "Part Time"
End Sub

my problem is that when i click on say Contract for example....the 5 jobtitles appear fine in the listbox..but if i click contract again..the items for contract duplicate ...so I end up with

IT Auditor
IT Project Manager
Operations & IT Coordinator
Service & Support Manager
Senior Engineering Manager
IT Auditor
IT Project Manager
Operations & IT Coordinator
Service & Support Manager
Senior Engineering Manager

items repeat over and over again........

so my question would be how would i stop these items duplicating?...and how would i go about clearing a listbox when i switch over to another jobtype..like permanent...because contract jobtitles remain when i switch...

(ps)ive only been using VB6 for about 3 weeks now,so I apologise for my lack of knowledge...

thanks for anyones input.

Welcome to VBForums! :wave:

You'll have to clear the list before adding new items:

VB Code:

Private Sub Cbojobtype_Click()
    [B]Cbojobtype.Clear[/B]
        If '...

I added vbcode tags to your post to make the code look more like vb code.

Martin sorry for not using vbcode tags,I will in future.. :)

Gavio...thank you very much for the reply :) ,Im not really sure how to code that..tbh .but I'll play with it for a few more hours...thanks though I appreciate the help.

what gavio meant was:

VB Code:

Private Sub Cbojobtype_Click()
    [B]lstjobtitle1[/B].Clear
    If Cbojobtype.Text = "Full Time" Then
        'etc.

VB Code:

Private Sub cboJobType_Click()
      lstJobTitle.Clear '====Clears the list before adding items===='
 
If cboJobType.Text = "FULL TIME" Then
 
      lstJobTitle.AddItem "IT Manager"
      lstJobTitle.AddItem "IT Sales executive"
      lstJobTitle.AddItem "IT Field technican"
      lstJobTitle.AddItem "IT Procedure director"
      lstJobTitle.AddItem "IT Director"
      
 
   ElseIf cboJobType.Text = "CONTRACT" Then
      
      lstJobTitle.AddItem "IT Auditor"
      lstJobTitle.AddItem "IT Project Manager"
      lstJobTitle.AddItem "Operations & IT Coordinator"
      lstJobTitle.AddItem "Service & Support Manager"
      lstJobTitle.AddItem "Senior Engineering Manager"
      
     
   ElseIf cboJobType.Text = "PART TIME" Then
      
      lstJobTitle.AddItem "Ecommerce consultant"
      lstJobTitle.AddItem "Network Engineer"
      lstJobTitle.AddItem "Programmer"
      lstJobTitle.AddItem "Test Analyst"
      lstJobTitle.AddItem "QA Manager"
         
 
   
End If     
End Sub
