Re: how can i use a straight c function in a C++ program?

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"
}

Custom Formatting in VC++

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. Confused | :confused:

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! Sleepy | :zzz:

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 Smile | :)

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>

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)

Plz if you can help me in sending the TCP packet.
Any website,code for sending the TCP packet.

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);

Visual C++ .NET bug?

Davide Pizzolato9-Mar-03 20:21

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 Frown | :(

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. Confused | :confused:

in fact, another way to fix the problem is writing the constants with the "f" suffix: 1.403f and the routine works

Hi,

I insert a string table in my dll resource eidtor, and then export a fuction from this dll. in that function one of string IDs in the string table is showed by a Messagebox. The problem is: this message box shows nothing.

the following is my code:

Inside DLL

<br />
#include "Resource.h"<br />
<br />
__declspec(dllexport) void LoadMaya();

void LoadMaya()<br />
{<br />
	CString strMaya;<br />
<br />
	strMaya.LoadString(IDS_MAYA);<br />
	AfxMessageBox(strMaya);<br />
<br />
}

Inside EXE

#include "..\MyDll\Maya.h"<br />
<br />
void CDllExeDlg::OnOK() <br />
{<br />
	// TODO: Add extra validation here<br />
	LoadMaya();<br />
	<br />
	CDialog::OnOK();<br />
}

<br />
Inside String Table

ID Value Caption

IDS_MAYA 100 Maya Culture

Please single out the bug for me, thank you

Try:

void LoadMaya()
{
  CString strMaya;

  HINSTANCE hsav= AfxGetResourceHandle(); 
  AfxSetResourceHandle(theApp.m_hInstance); // theApp is CWinApp-derived

  strMaya.LoadString(IDS_MAYA);
  AfxMessageBox(strMaya);

  AfxSetResourceHandle(hsav); // put-back
}
