Perhaps if you make a batch file and run that batch file when closing your app.
Make loop in your batch file that tries to delete your EXE!
but your batch file will still be there... Frown | :(

So,how can I make it run only for ONE time? Like trial version programs.

Hi Mazy

How can you make it delete itself, it will be in use at the time and therefore cause an access denied prompt???

alternatively i have just thought, Make a second app and get that to delete the first, waiting for the first one to delete. Therefore you will be left with the second app. Which is just there to remove the first and contains no info. alternatively again make a batch file

Sorry, but then I can't help you! Frown | :(

But if you want an unsafe way to do it: Write something to a file (EXE, DLL or just a file) in binary (of course) and then read from that file to see if it has run before!

Understand?

Yes.

Copy the file to a temp dir and run it from there. When the app ends, it should add a registry entry (I forget which) requesting Windows to delete it the next time Windows restarts.

How can get the CPU unique ID?

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....

Visual Studio .NET class overloading

dazinith10-Apr-02 3:50

dazinith

10-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

Joel Holdsworth10-Apr-02 6:13

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.
