Problems with loading data into ComboBox which is depended on another combo box click

[NickProstrelchuk 0]

Hello,

I have a problem with loading data into combo box.

I have two combo boxes: one with Mailbox Server's names and one with Mailbox's names.

If i selected Mailbox server from first Combo Box second combo box should load elements according to the selected Server name.

I've written a code which selects server name from first combo box but second combo box hasn't loaded any items at all.

When I've tried to perform this steps manually, all has worked fine.

I think such situation is occurred because _GUICtrlComboBoxEx_SetCurSel method do not send any event to the control.

I've tried to use ControlCommand method with "SelectString" and "SeCurrentSelection" params. But this solutions did not resolve my problem.

Here is my peace of code:

Local $index = _GUICtrlComboBoxEx_FindStringExact(ControlGetHandle("Select Mailbox", "","[NAME:m_serverComboBox]"),"Server")
    
    If $index > -1 Then
        
        _GUICtrlComboBoxEx_SetCurSel(ControlGetHandle("Select Mailbox", "","[NAME:m_serverComboBox]"),$index)

    EndIf
    Sleep(1000)
    
      $index = _GUICtrlComboBoxEx_FindStringExact(ControlGetHandle("Select Mailbox", "","[NAME:m_mailboxComboBox]"),"Mailbox")
    If $index > -1 Then
        _GUICtrlComboBoxEx_SetCurSel(ControlGetHandle("Select Mailbox", "","[NAME:m_mailboxComboBox]"),$index)
        
    EndIf

Could you please help me to solve this problem.

Best Regards,

Nick Prostrelchuk.

You may need to send CBN_SELCHANGE as a WM_COMMAND. Note the comments from MSDN: CBN_SELCHANGE Notification Code that this is not done automatically:

The CBN_SELCHANGE notification code is not sent when the current selection is set using the CB_SETCURSEL message.

That CB_SETCURSEL is what you sent with _GuiCtrlComboBoxEx_SetCurSel().

P.S. I thought this sounded familiar...

Thanks for you reply. I just added ControlSend method with according event and now all works fine.
