In fact, i just have to use some functions from a lib written in C,so that why
i do it this way. i use extern "C", so i can use those functions' names directly(C++ do name-mangling, you know).

Ah - I see. But if they're in a lib, how do you have the c code, instead of just the header ? Or was the example flawed ?

Yes, you are right. i just have its header files. I want to call the functions directly. how can i achive this target?

Have you tried this way, it compiles fine under VC++6.0, if not it could be a c++ builder specific problem.
in my_c_func.h:
int a_c_func(void);
and in your cpp file:
extern "C" {
#include "my_c_func.h"
}

Yes, it works!
Baris, thank you, you are my hero of today.
and Christian, thanks for your immediate responses.

The background: I have some ascii files in my project for use with custom build.
They all have the same file tag (*.PMC)
These files have specific formatting, so I want have VC++ (6) recognise them, and
use keyword colouring, auto indent etc. MSDN implies that you can do this (they give
a custom html (*.hlx) example) but it doesn't work. 
Has anyone succeeded in this? What steps did you follow that I may have missed?
I can work without it, but I'm lazy and like to get my IDE to do the work for me! 
Iain.

I have seen a few of Tree/list Ctrl combinations, but all of them are showing tree in the first column of the list, and the parameters of nodes in the rest columns.
I need to write <b>Ctrl that would show tree nodes in columns of the list</b>( nodes of the same level in the same column).
Has anybody solution or some guidlines how to do that?
Please, don't forget that parent nodes has to make column span if the grid is shown 
I think that somthing similar I have seen on some web pages but i can't find if now ;(
<b><big>Any help would be appreciated !!!!!! thx!</big></b>

Yes I'm going to do that
Any suggestion where to start from? What kind of base class to use, or just do I have to start from CWnd ?
Anyone?!??!
Every suggestion is welcome!

dear all,
i'm facing a very wierd problem in the following code (only SDK, No MFC)
int i= GetPrivateProfileString("Paths", "InputFile", " " ,inp,MAXCHARS, IniPath);
i get the following error ->
C:\Documents and Settings\rishabhs\Desktop\Source\source\window_click\window_click.c(123) : error C2143: syntax error : missing ';' before 'type'
now when i use following code, every thoing is fine ->
int i;
i = GetPrivateProfileString("Paths", "InputFile", " " ,inp,MAXCHARS, IniPath);
i've no clue whatsoever regarding this problem
any ideas!!!!!!!!
regards

There is a subtle difference between the two statements. The first is an initialization. The second is an assignement. Maybe you are receiving an error because the compiler is refusing to initialize an int with a DWORD? Note that the assignement is legal due to built-in type conversions.

1) ModifyStyleEx(NULL, WS_EX_TRANSPARENT );
or you can just call SetWindowPos directly....
Use Spy++ to verify styles.

any body know
Is it neccessary to make Psuedo Header to send TCP Packet.
Can I send the packet without it.
Can I use
SOCKET s = socket(AF_INET, SOCK_RAW, IPPROTO_TCP);
directly
instead of SOCKET s = socket(AF_INET, SOCK_RAW, IPPROTO_RAW);
Plz help me and tell me the way i can do without it because the packet is not been sent on to the network using Psuedo Header.
Reply me soon

If you dont want the TCP headers then create a datagram socket (SOCK_DGRAM, protocol 0) and then you can manage everything yourself. From memory, the SOCK_RAW is only available to privileged programs (although this may not apply in a windows environment)

I want to use the TCP headers but the tcp packet is not going on to the network.
Plz if you can help me in sending the TCP packet.
Any website,code for sending the TCP packet.
Reply me soon

If you set up the socket correctly then the TCP headers will always appear on the network, you dont need to create pseudo ones or even know they are there. I always use this:
int handle = socket (AF_INET, SOCK_STREAM, 0);

this code works if compiled with VS6, but gives wrong results with VC++.NET
int Y,U,V,R,G,B;
Y = lYUVColor.rgbRed;
U = lYUVColor.rgbGreen - 128;
V = lYUVColor.rgbBlue - 128;
R = (int)(Y + 1.403 * V);
G = (int)(Y - 0.344 * U - 0.714 * V);
B = (int)(Y + 1.770 * U);
replaceing the declaration of Y, everything is ok.
int U,V,R,G,B;
float Y = lYUVColor.rgbRed;
U = lYUVColor.rgbGreen - 128;
V = lYUVColor.rgbBlue - 128;
R = (int)(Y + 1.403 * V);
G = (int)(Y - 0.344 * U - 0.714 * V);
B = (int)(Y + 1.770 * U);
where is the bug? in the compiler or in the code?

Hi,,
I think the problem is in the code 
Y + 1.403 * V<br />
Y - 0.344 * U - 0.714 * V<br />
Y + 1.770 * U (do you write a jpeg decoder/encoder?)
you use U (an int) and Y (an int) so te hole equation uses ints which means loss of accuracy (int truncates what comes after the period)
so when you use Y (float) the compiler does not truncate them...

it's for CxImage
you'are right, but 1.403 is not an integer, so the * operator should give a floating point result, while in this case the result seems an integer.
in fact, another way to fix the problem is writing the constants with the "f" suffix: 1.403f and the routine works

Does any one knows where can i find the details / help about the API interface of VSS. ??
Any sample programs, tutorials etc. ??
I looked into MSDN and found only 1 page of documentation
I want to devlop an Addin which listens to the events of VSS(client / server) and performs some actions.
Please help.
thanks and regards.
