I have a tab control, contents of which are displayed by a CDialog. This dialog contains different controls on it. I am having following issues :-
1) After I run my app, if I put another window on top of it (say calc.exe) and switch back to my app, I see the area convered by calc.exe is erased!
2) I have a menu which pops up if I do a right control on the header of my Clistctrl .. after the menu goes away, the area covered by the menu is erased and comes back only when I move my mouse over the area...
3) If I hit enter the contents on the tab control (which are displayed by CDialog) go away completely!

How do we know that array is emtry or not?
here is a piece of my code
char* pch = "";
char sEnglish = "";
// if pch is "" and sEnglish is "" then
// this ((pch!="")||(sEnglish !="")) is true, why? it should not be true, it must be false, or am i doing wrong?
// if that is true, it fails on strcat("","")
if ((pch!="")||(sEnglish !=""))
how do we know that pch is ""? or not? and
why strcat function fails when both of input paramets are NULL?
