Assuming the processor supports unique serial number:

#define cpuid __asm __emit 0fh __asm __emit 0a2h
UINT PSN, ID1, ID2, ID3; 

__asm
{
mov eax, 01H
cpuid
mov PSN, edx
}

if (PSN&<s>0x20000</s> 0x40000) //Check bit 18 if serial number is available 
{
__asm
{
mov eax, 01H
cpuid
mov ID1, eax
mov eax, 03H
cpuid
mov ID2, edx
mov ID3, ecx
}
}
else
{//Processor does not support unique ID
}

If everything works out ID1, ID2, ID3 should contain the unique 96 bit ID. I havn´t tested the code since I don´t have a PIII, but I hope it works...

More info on cpuid here (pdf).

Hope this helps

There was a litte bug in the sample program... Blush | :O

Bit 18 is 0x40000, not 0x20000. If you havn't discovered it yourself I think I should save you some trouble....

CBitmap m_pGenBitmap = new CBitmap();

CClientDC dc(NULL);
int nWidth = 128;
int nHeight = 128;

HDC hDCScreen = dc.GetSafeHdc();
HBITMAP hbm = ::CreateCompatibleBitmap(hDCScreen,nWidth,nHeight);
if (hbm != NULL)
{
HDC hDCGlyphs = ::CreateCompatibleDC(hDCScreen);
HBITMAP hbmOld = (HBITMAP)::SelectObject(hDCGlyphs, hbm);

Visual Studio .NET class overloading

dazinith10-Apr-02 3:50

Can someone tell me the easiest way in .NET to overload a base class function? basicly what I've been doing is looking at how the base class and just copying/pasting the code and modifying it, but i figure there has to be a built in way to overload a function without doing this?

thanks!

How do I manage to use an own Icon for my executable (no MFC used yet) so that the usual Windows-Icon for exes is replaced by my Icon ?

hmm, I think this question is answered several times in this forum, it might even be in the Q&A section. Anyway, to change this icon, modify the Icon whose ID is IDR_MAINFRAME, remember to change both of them, the standard one (32x32) and the small one (16x16).

I know that procedure when I have a for example dialog-based app using MFC. But I dont use MFC and aint got any resources yet. What do I have to do ? Confused | :confused:

Re: Program-Icon

The resources are crucial - if you don't have them you can't have icons. When explorer try to flash an icon up, it just uses the first icon it comes across in the resource sector. Usually we arrange things so that if you have several icons, the main one is the first one uncovered. There really is no way around you making an .rc, and doing it that way - not that I nkow of anyway.

I hope that helps.

Hi.
I am developing a dialog based app.a costum header file for common defination has been included in stdafx.h,when i build the app,the compiler say the common definations is redefined in appname.obj.However after I install the latest MS Platform sdk,the problem disappear.Please tell me why?

I should think it would depend quite a bit on just what you were defining in that header file. Mind sharing?

Developers that like shiny objects also dig case mods and scratch-and-sniff stickers.

Problems using MsWord as a container

Hi,

I have created two ActiveX controls that are on the same DLL file ( developed using ATL). I can insert them in the "Test Container" without problem.

But If I try to insert the newest one in Ms Word, it gives me the following error:

"The server application, source file, or item cannot be found. Make sure the application is properly installed, and that it has not beed deleted, moved, or renamed"

I've try to insert it there, from an Automated App, from the Insert Object menu, and from the Insert ActiveX from VBA toolbar.

I tought that it was maybe because some temporary files ( ".exd"), but I have search for that *.exd files and nothing found...

Any idea about that ?, Thanks in advance

MFC6 in Visual Studio.NET

Hi,

I'm working on a rather huge project, and we would like to start using Visual Studio.NET in the near future. However, we will not be using MFC7 in the next few months; we'd like to stick with MFC6. Is it possible to work in VS.Net while developing with a previous libraryversion?

No,You have to use MFC7 there but if you delevop half of your project with MFC6 then you want to swicth to MFC7(VC.NET),there is no problem and you can proceed your project with new version.

Are you sure about that? I have opened my project in VS.Net and MFC7, but there are a lot of things different in MFC7, compared to MFC6. I get a lot of compile-errors I didn't get with MFC6. So, I can understand that MFC7 will behave very differently compared to MFC6.

I have figured out that I can tell VS.Net to use different folders for include and sourcefiles, so it will include MFC6 files, however I can't manage to tell the linker it should link with MFC42.dll instead of MFC70.dll.

I really hoped I could use MFC6 in VS.NET because I don't feel very much like testing the entire project (which is rather huge) to see on what points it differs from the previous library.
