So you need MFC linked to it anyway.
You can choose the shared MFC variant.

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.

If your main application[s] (the one[s] that will use the dll) is/are MFC then you can choose any of the three. If you want to use the dll from non-MFC applications then you're limited to 1 or 2.

In my view you're probably better sticking to 1 or 2 anyway. Shared MFC DLL is usually the sensible option but there are occasionally circumstances where that creates untold hassle and it's easier to use static MFC linkage.

In summary: if your requirements are fairly straightforward then go for standard dll with shared MFC dll; if things might get complicated go for standard dll with static-linked MFC. (You can easily change between the two if necessary). In either case the calling app does not have to use MFC, but it can.

This was what I wanted to know thanks. The "requierements" are explained in my answer above. So I guess I am going to select the third option.

(in the future I will try to recode my Application without MFC and in multilanguage, with some improvements I have privately thought, then I will try to do it portable and compatible, I am still learning)

Where and how can I get CPU Thermal Design Power (TDP) data?

I can't find the information to get Thermal Design Power(TDP)data from CPU.
Through CPUID or MSR or somewhere? and base on which datasheet?

Hello,

I want to convert a character into its ascii code or the ascii code into the character.

For ex from 95 I want 'a' if that is the ascii code .Is there any function which can do that like atoi(),itoa().

Drawing Icons

Hi,

I'm trying to draw a small icon using a CPaintDC class. I've managed to get it to draw the large version of the icon, but not the small version. The code i've tried is as follows... but doesn't make the icon appear!

CPaintDC dc(this); // device context for painting
.
.
.
.
m_hIcon = ( HICON ) ::LoadImage( NULL,
MAKEINTRESOURCE( IDI_ERROR ),
IMAGE_ICON,
16,
16,
LR_DEFAULTCOLOR );
dc.DrawIcon(x, y, m_hIcon);

Thanks.

Whats return value of LoadImage?

Re: Drawing Icons

dsclee30-Oct-07 1:58

It came out as zero... so it clearly couldn't find the icon. I've now managed to get the icon to display using a different method.

m_hIcon = ::LoadIcon(NULL, MAKEINTRESOURCE (IDI_ERROR));
::DrawIconEx(dc, X, Y, m_hIcon, 16, 16, NULL, NULL, DI_NORMAL);

This seems to work Big Grin | :-D

If there's anything dodgy with using this please let me know!

what happens when use of this code

m_hIcon = ::LoadIcon(AfxGetApp()->m_hInstance, MAKEINTRESOURCE (IDI_ERROR));
::DrawIconEx(dc, X, Y, m_hIcon, 16, 16, NULL, NULL, DI_NORMAL);

That doesn't work.... as the m_hInstance doesn't contain the default icons. I got access to the icons through putting NULL. (It says to set it to zero on MSDN.)

Its all working fine for me!

Hai all

I'm using the active desktop Interface to get the current destop item count using the function GetDesktopItemCount(&count,0);

But on my desktop there is more than 10 things and the count value got by GetDesktopItemCount() is '1'.Why is it so.

Please reply.

My OS is XP.

Thanks in Advance

How can I simply read/write specific values from an Excel spreadsheet (e.g. case at Row2; Column2) using C++?

That's all what I need to do and I'd rather not use the cumbersome classes that I've seen posted here.

Help please, I've been stuck on this for ages!! D'Oh! | :doh:

Using Excel Automation is by far the easiest method.
