Control Array Access Problem while loading panel on 2 Tabs

[CVI_Zorro]

I am using LabWindows CVI 10.0. My intention is to programmatically disable a control array in a panel.

Problem:

       I am loading a panel with control array in TabControl pages -  Tab0 and Tab1.

Error occurs, While programmatically accessing through below functions.

GetCtrlArrayFromResourceID( Tab0_panel, CTRLARRAY) -  Able to get resource ID.

GetCtrlArrayFromResourceID( Tab1_panel, CTRLARRAY) - Not able to get resource ID.

Its giving error as Resource ID not found in UIR.

Error picture i have attached below for reference.

Please give some suggestions.

Hi Zorro,

just a guess: tab panels are somewhat tricky, one of the usual stumbling blocks is the wrong handle...: did you use GetPanelHandleFromTabPage ( panel_handle, PANEL_TAB, 0, &tabpanel_0_handle ) etc.?

[CVI_Zorro]

No i Used, GetCtrlArrayFromResourceID(tab0_panel, CTRLARRAY);

Because for the 1st loaded panel i am able to retrieve CTRLARRAY Ref.

But for 2nd one can't able to retrieve

Ok, if you didn't use it so far you should use it now  : If you are accessing controls on a tab panel you have to use the correct panel handle using the function GetPanelHandleFromTabPage, you can not simply use the constant defined in your UIR.

Have a look at the example TabExample.cws for an example of this function.

Hi Wolfgang,

Thanks for the reply.

But i am using Easy Tab Control.. Is it same as Tab?

[Wolfgang · Accepted solution]

Ah,... this you should have mentioned earlier...: No, it's not the same.

Moreover, EasyTab is outdated and superseded, so I suggest moving your UI to true tab panels

[CVI_Zorro]

OK, Wolfgang. I will try New Tab Control...

Thanx for ur ideas.

My pleasure!
