Hello. I am using the TabControl within VB6 to allow the user to enter multiple instances an entity for a record. I created a form which contains the controls to collect data about each instance of the entity, and I use the code below to create new tab items so that the user can enter details for each instance of the entity.

'Create new instance of entity on form

    Dim strTabCaption As String
    Dim iEntityNum As Integer

    If iTabCount = 0 Then    'a public counter
        TabControl.Visible = True
        Set pageEntityInfo = New pageEntityInfo
        TabControl.InsertItem 0, "Entity 1", pageEntityInfo.hwnd, 1
        iTabCount = 1
    Else
        iEntityNum = iTabCount + 1
        strTabCaption = "Entity " & iEntityNum
        Set pageEntityInfo = New pageEntityInfo
        TabControl.InsertItem iTabCount, strTabCaption, pageEntityInfo.hwnd, 1
        iTabCount = iTabCount + 1
    End If

My question is...once the user finishes entering data on each tab (instance of pageEntityInfo) and saves the parent record, I want to save the parent record details and then loop through the tabs (iTabCount) and save the details for each Entity instance (ParentRecordID, EntityNum, EntityName, EntityType...). How can I collect data from the controls on each instance of pageEntityInfo per tab (i.e. how do I specify that I want the data from pageEntityInfo on TabControl(i))?

I know that I could create pageEntityInfo1, pageEntityInfo2, etc. and limit the number of Entity instances the user can add for each parent record, but I would prefer to re-use one form (pageEntityInfo) and allow the user to enter 'n' instances.

Thanks for your help!

Think you have add Array variable and add all forms to it.

Thanks, Oleg. I'll try that.

I think, pageEntityInfo is a form-object.

You can do this:

dim xForm as Form

for each xForm in Forms

if typeof xForm is pageEntityInfo then

' do anything

endif

Thanks for the reply, Baldur. That will work since I don't need to know which instance of the form I am on...I am saving the data on each instance.
