The problem is, when

m_check19).

Which is one of the many reasons to not use the function. See here for more.

Have a CButton member variable for each checkbox. Use the SetCheck() and GetCheck() methods.

You could also use the CheckDlgButton function.

CheckDlgButton(IDC_CHECK20, 1);<br />
CheckDlgButton(IDC_CHECK21, 0);<br />

From MSDN:
"That manifest file must be named correctly (<your .exe="" name="">.manifest) and must be in the same directory as the .exe file for your application to take on the correct appearance"

thanks for the reply, but..

manifest file is included as a resource, not as a seperate file.

Yes, i've tried using it as a seperate file, but it does not work. (plz note, I've other exes that work correctly. The problem occurs only if I use the resource in this dll)

An actual profiler would be your best bet, but you can use GetTickCount() to get reasonably close.

I haven't used the profiler in VS2005 but the profiler in VC++6.0 is useful.
It shows the number of times a function was called in addition to the time spent there.
You can also use it to get an idea of which sections of your code are used under various circumstances.

It's not in all editions (Professional and Enterprise, IIRC) - if you have it it'll be on the Build menu, right at the bottom. You need to enable profiling in the link options first.

Thanks. That menu option was not initially enabled because I was missing the following registry value:

How to display icon on the screen???

Hi,
In my app i need do draw a icon on a specific place(each time
on a different place).

I added the icon to my resources(it's ID is IDI_Target_ICON)
and I'm using this code(I want to display the targets on a thread) :

UINT ShowTargetsThread(LPVOID lpvoid)
{
	TargetsViewDlg *dlg = (TargetsViewDlg *)lpvoid;
	CDC *dc;
	CRect rect;
	int nX = 0 , nY = 0;
	HICON hIcon;
	HBRUSH hBrush = CreateSolidBrush(RGB(0, 0, 0));
		

	dc = dlg->m_TargetsViewBMP.GetDC();
	dlg->m_TargetsViewBMP.GetClientRect(&rect);
	//hIcon = (HICON)LoadImage(dlg->, MAKEINTRESOURCE(IDI_ON_ICON), IMAGE_ICON, 16, 16, LR_DEFAULTSIZE);


	for(int i = 0 ; i < 20 ; i++)
	{
		nX = (rect.right - rect.left) / 2;
		nY = rect.bottom - (i * 10);
		DrawIconEx((HDC)dc, nX , nY , hIcon, 16, 16, 0, (HBRUSH)hBrush, DI_IMAGE);

		Sleep(200);
	}
	return 1;
}

The problem is I don't know how to load the icon.

Anyone?

Eli D'Oh! | :doh:

What part of what control are you interested in? Some controls have text, some do not. Some have borders, some do not. For starters, there's GetBkColor().

Without a specific example, I can't say for sure.

This almost sounds like "skinning." Since that technology is all about painting the various parts of a window, I'd suggest a thorough reading of it.

ActiveX control versioning

Friends,
I usually develop 'ActiveX controls' using "MFC ActiveX Wizard". In the past, i simply develop ActiveX control and distribute it along with the client side application.

This time i am in different situation. As usual, i developed a control and distribute it with my client application. But now i've enhanced the same control. I've added some new interfaces and not touched the previous interfaces. I came to know from somewhere that there is a method of proper versioning of ActiveX controls and COM components. And i am required to 'increase' the version of my activeX control before distributing it.

Can anyone tell me how to control the version of those 'ActiveX controls' which evolve with the passage of time. Also tell me the method to do so in MFC ActiveX controls.

Ahsan
