without any code we can only guess...

Are you using LoadPanelEx instead of LoadPanel?

[marwasagem]

yes  im using LoadPanel 

[Wolfgang]

so you should replace it with LoadPanelEx...

[marwasagem]

no it dosn't work.

i will explain again im my project i have only the main and DLLs, in the DLL i put all my functions and need to show results (exemple by using tab control,...)   on the  front panel. panel is loaded in the main.

Is the problem solved?
This is a very descriptive error.
Probably the problematic line is also highlighted.
Maybe you are not programming the control arrays correctly..?
It is not possible to comment without some code we can try and produce the error...

If the use of a Tab control, the "TABs"  are in affect a different "PANEL" so the control on a tab is not the panel handle name but the tab panel name. The PANEL_CONTROLS  and the PANEL_TAB_CONTROL name are  in different panels.I agree with ebalci, without the project files, this will be hard to debug the problem.
