Yes,but all applications are MFC based

But the code that actually communicates with PowerPoint is not.

But I can't choose automation class from class wizard for non MFC application

Please help me to find a proper sample

I just created a Win32 project, opened ClassWizard, clicked the Automation tab, and created an Excel class from its type library. It worked fine.

I have also created a non MFC win32 Project but i can't add class from type library using class wizard.

I Think you have created MFC based win32 project.

If i am wrong please tell me the detailed steps.

Lay out the exact steps you are using.

You would be wrong in your thinking.

Which shows nothing of how you are attempting to create the PowerPoint classes via ClassWizard.

I want to change background color of ListCtrl.
I try to use this function

<br />
m_List.SetBkColor(RGB(76,85,118));<br />

but no work

Please advise me for this issue,May be it need more of code

Thanks

See here.

"To have a respect for ourselves guides our morals; to have deference for others governs our manners." - Laurence Sterne

add message OnCtlColor
and add this code inside:

<br />
	switch(pWnd->GetDlgCtrlID())<br />
	{<br />
	case IDC_LIST1: <br />
		pDC->SetBkColor(RGB(0,0,0)); <br />
		hbr = ::CreateSolidBrush(RGB(0,0,0)); <br />
		pDC->SetTextColor(RGB(0,255,102));		<br />
		return (HBRUSH)hbr;<br />
		break;<br />
}<br />

then you are there where you wanted;)

Hi,

I am using ON_COMMAND_RANGE_HANDLER(ID_FIRST,ID_LAST,Onmenuitemselected)

The problem is When the user logs in as admin all the menu items are displayed and hence proper menu id gets invked.

If the user logs in to the application as operator, he does not have proper privileges , hence some of the menu items will not be displayed.

At this time, when the user clicks , third item in the menu (ID_FOURTH),ID_THIRD gets passed as wid.

Is there any way to handle this?

Regards,
Anitha

Menu IDs should stay the same whether the option itself is displayed or not.

It does not when he assembles the menu entirely "by hand".

Let's think the unthinkable, let's do the undoable, let's prepare to grapple with the ineffable itself, and see if we may not eff it after all.

Why would that make any difference? Whether the menu is "designed" at design time or at run time, the IDs should all be known ahead of time.

"To have a respect for ourselves guides our morals; to have deference for others governs our manners." - Laurence Sterne

No, Menu id's are same they r defined in header file like

ID_FIRST 2001
ID_SECOND 2002

But when some menu items are not displayed, the ON_COMMAND_RANGE_HANDLER takes the menu items in sequence.hence , wrong functionality gets invoked.

If ON_COMMAND_RANGE_HANDLER() (which I was not able to find on MSDN or Google) is not working, try using:

ON_COMMAND(ID_FIRST, Onmenuitemselected)
ON_COMMAND(ID_SECOND, Onmenuitemselected)

You are probably better off when you use a menu resource with the maximum of entries and then disable/hide some depending in the OnUpdate...() handler, depending on the application state.

Hi. I have a CTreeCtrl menu, and every once and a while I refresh the tree by calling DeleteAllItems() then re-adding all nodes. How can I prevent display updates of the the control until all items are added? Right now when the tree is refilled, you can see it all being deleted then filled up. All happens in a flash, but you can still see it refresh and I'd like to get rid of that if possible. Thanks!

Use the SetRedraw() method.

Thanks! I knew it was something simple, I just couldn't find the method. Wink | ;)

class A {};
class B { public: B (A a) {} };

int main()
{
A a;
B b=a;// this statement gives no error! How? please explain
}

Because this statement calls the constructor directly, it's equivalent to...

B b(a);

Code must be written to be read, not by the compiler, but by another human being.

Have you set a breakpoint in B's constructor?
