My App hangs...

[Elias Montoya]

I have a tab control with 3 Forms. Each form is designed also in Firefly and i attach it to the tabs of the tab control using this code:

Code Select Expand

'------------------------------------------------------------------------------------------------------------------------                                     
Function SetTabChildWindow(ByVal hCtrl As Long, ByVal nTabIndex As Long, Hdlg As Long, Caption as String) As Dword

   Local TCITEM  As TC_ITEM
   TCITEM.mask = %TCIF_PARAM
   TabCtrl_GetItem Hctrl, nTabIndex, TCITEM                           
   TCITEM.lparam = Hdlg
   DLGS(nTabIndex) = Hdlg
   TCITEM.mask = %TCIF_PARAM
   SetParent Hdlg, HCtrl
   Local RC As Rect
   GetWindowRect Hctrl, RC
   SetWindowPos Hdlg, 0, _
                  0, 24, _
                  (rc.nRight-RC.NLEFT)-4, (rc.nBottom-RC.NTOP)-25, _
                  %SWP_NOZORDER Or %SWP_NOREDRAW
   ShowWindow Hdlg, %SW_HIDE
   TabCtrl_SetItem Hctrl, nTabIndex, TCITEM
   FF_TabControl_SetText (Hctrl, Caption, nTabIndex)   
   Function = %true

End Function

When i press a button in the dialog containing the tab control, it works. But when
i press a button in a form contained in the tab control, the app hangs, even if the
button procedure is empty.

Any ideas why is this happening?

Why aren't you using FireFly's built in method of assigning the child Forms to the Tab Control? Why are you trying to do it manually? It would be a lot easier to use the "Custom" property of the TabControl control and assign the child Forms to each tab. Am I missing something about your approach?

Is there a Firefly Approach? I dont know it. Where do i learn it?

There sure is. The "Custom" property of the TabControl control and assign the child Forms to each tab. It is very easy using this method. I have attached a screenshot of the "Custom" dialog that appears when that property is selected.

I saw that, but i thought it was only for naming and adding the tabs.

How do i specify a dialog for each tab? I tried everything but i cant attach
a dialog to a tab from there. Do i have to set a special flag in the dialogs
i want to use in the tabs?

The "Child Page Dialog" combobox doesnt display any options, and i cant type
anything there...
