By using Shared Memory, IPC or Sockets. Would depend on your need and how you would like to implement such a thing also check passing through command line arguments if you are running the second exe from the first one.

Somethings seem HARD to do, until we know how to do them.

Probably using WM_COPYDATA message is the simplest way to.

Gosh! that's my favorite, however i would prefer registered message for sending window data!

Hi,

IMO the easiest way to do that is through a command line argument: just add a textual argument
to the ShellExecute() you already and let the called EXE watch and obey its command line.

UINT64 behavior VC6 C++

Hi,

the VC6 compiler gives me problems:

const UINT64 a = 0x0000000080000000;
results in just that, however

const UINT64 b = a << 1

results in 0x0000000000000000 !!!!

What am I doing wrong ?

Is there any way to force b into the required 0x0000000100000000

thanks,

Thank you for your answer.

Sorry, I should have mentioned that I try to do this in a header file.
In in function inside cpp file it works ok.

Also, as a global variable it does not work.
Maybe you could try that.

Thanks,

dynamic array use?

15-Jul-08 23:09

dear all

int *
nColumnCounts1
nColumnCounts2
nColumnCounts3
nColumnCounts4
nColumnCounts5

=new int[constant];
the following is dynamic arrays, and nColumnCounts1,nColumnCounts2,nColumnCounts3 were calculated already correctly, now i would like to calculate nColumnCounts4,nColumnCounts5 as per following formular. is this right way?

nColumnCounts4[m]=abs(nColumnCounts1[m]-nColumnCounts2[m]);
nColumnCounts5[m]=abs(nColumnCounts2[m]-nColumnCounts3[m]);

and then i can get new nColumnCounts4,5. however i couldn't correct result. anyone has suggestion to me, thanks a lot

av1, av2 should be declared double (or float).
Then change the above expression to:

av1 = (double)a4 / _iBoundwidth;
av2 = (double)a5 / _iBoundwidth;

gentleguy wrote:
s1=s1+pow(nColumnCounts4[m2]-av1,2.0);
s2=s2+pow(nColumnCounts5[m2]-av2,2.0);

Again, s1, s2 should be declared double.
Those declarations will fix the (otherwise wrong) above expression .

BTW: Are you aware that all that static_casts you're using are useless (and contributes to overall code entropy)?
