Hello,

I have a CMenu class object with some menu options.When I try to disable a particular menu option I am not able to do it.I have used the following

EnableMenuItem(6,MF_DISABLED | MF_GRAYED );
But if I use the following
CString R;
GetMenuString(6,R,MF_BYCOMMAND);
I get the particular string of Id 6
What I sould do to disable the menu_id?
Thanks
Prithaa

Use this
and
Set the m_bAutoMenuEnable to FALSE in the constructor of
CMainFrame so no ON_UPDATE_COMMAND_UI or ON_COMMAND handlers are
needed.

If it's an MFC app then you should use ON_UPDATE_COMMAND_UI macro and handle disabling and enabling there.

If you have done the OnCmdMsg as I said earlier, to disable the menu you need to return FALSE from that funtion.

Is this the correct way? ON_UPDATE_COMMAND_UI macro is provided for this purpose right.

When I checked the ON_UPDATE_COMMAND_UI wasn't arriving..

Please try.

Create a menu dynamically
Set it to mainframe using the SetMenu().
Now the menu will be disbaled since it dosent have command handler.
So I stepped into the MFC code and found out that handling the OnCMdMsg() will solve the pblm( I forget what you said in the IPT class D'Oh! | :doh:

).

Please check the ON_UPDATE_COMMAND_UI is coming in this case.

Launch Application after Setup

I created a Setup with Visual Studio and all works nice.

I like to start the application automatically after the setup is closed.
(probably add a new page with the demand to open the app or not )

Has anyone an idea how to start it?

Big thanks

Dialog repaint

Hi all:

I have a modeless dialog in which I have done not much inside its OnPaint, but when this dialog overlapped randomly, this dialog appears out of shape on the surface, should I send WM_PAINT or WM_ERASEBKGND message, if so when should I send them?

Re: Dialog repaint

If you draw something directly on the dialog, all the drawing code should be put in the OnPaint handler. The dialog doesn't "keep" the drawing for you but you have to redraw everything again in the OnPaint handler.

Is that your problem ? If no, then I misunderstood your question.

I probably miss state the situation, on OnPaint I only call the DrawText, other than that I done nothing else, system handle all the rest paint operations.

it depends on what you exactly do. A repaint makes than sence, when all GUI changes are done.

It is also common style to update only some controls. For instance a status bitmap.

It makes also sence to divide forground and background painting.

Maybe you have to post more clearly your problem.
Anyway, don't send WM_PAINT directly,
use instead InvalidateRect and UpdateWindow functions.
