I have created sample dialog application in MFC.
Inside dialog a list control is displayed with 1000 column.
The header is not drawn properly.
Is there any problem with the header of CListCtrl?

Could you describe why "header is not drawn properly" I mean... what do you see?
Does it happens in all the columns? it starts from column number X?

PS: 1000 columns seems a little bit excessive to me, but... this is only an opinion, who knows what you want to achieve...

Is it possible to resolve this issue of header not drawing after 32767 pixel?

I agree with Joan Murt's comment. 1000 columns is not reasonnable. Even though it would work and display properly, do you really think the user can read that?

Try with a few columns (let's say 10) to see if your problem persists.
- If it doesn't, then consider displaying just a few columns at a time.
- If the problem persists even with a few columns, then you have a problem in your code. In that case you should post some code so we can analyse it.

It is not possible as far as I know. The only possibility is to make your columns smaller, or display fewer columns.

I resolved this by creating my own control, which is derived from CStatic.
I handled the drawing in my own class.
Since in my case I want to just display the information (other features such as column/row resizing and row selection are not required), it was easy to develop the control.
