Hi.
Anyone have any idea of how or what to use to plot a 3D curve in real-time?
I want the 3D curve to be drawn on the canvas in real time so that we are able to see the curve being drawn at which ever direction.
I have tried to plot the 3D curve using openGL and gnuplot but that is not in real-time.
Thanks!

Here is a sample of 3D function plotting.

From your code - use MoveWindow() or SetWindowPos(). or Do you want to allow the user to drag the dialog from it's corners and resize it?

Hi
i use this function in onPaint() funtion in
switch()
{
CDialog* dlg = (CDialog*)GetDlgItem(IDD_DIALOG_NSMESSAGE);
HWND hwnd = dlg->GetSafeHwnd();
SetWindowPos(hwnd,50,50,50,50,SWP_SHOWWINDOW) ;
}
but it does'nt work. Is it a right way or i have to do it by some othere way.

It is not.
You must understand cases, whenever OnPaint is called. That is not place to change size of window.

If you just want to change the size call...
CSize csSize( nNewWidth, nNewHeight );
SetWindowPos( 0, 0, 0, csSize.cx, csSize.cy, <code>SWP_NOMOVE</code> | SWP_NOZORDER | SWP_FRAMECHANGED );

Hello,
I have a CString in a CDialog and I want to print it in a Network printer.
I have been taking a look of the diffrent methods to do it but in all of them I have find problems,
For example:
1.-
filebuf fb( "prn:" );
filebuf fb( "prn:" );
cout = &fb;
cout << "testing";
Can only print to local printer.
2.- CView::OnPrint
I can't use it because I am using CDialog not Cview, CFormView.....
Fixing:
Does any way to print a CString using CPrintDialog?
Thanks in advance,
Best regards

QPrint may be what you are looking for.

Hi
When an project is created in VC6.0. It can be opened in VC.Net.
But if i create an project in VC.Net, can I open it in VC6.0.
Could i know in which file the version is serialized.

Hi
U can not open project in VC++ 6.0 which is develop in VC.Net. Because it is advance version so all vc.net features are not in VC++ 6.0.

No, but tools do exist to convert from VS2005 back to VS6.

NO, but you can achieve that manually by adding blank solution and project and copying files and setting into them

please i was confused a little
i have array of unsigned char where if i print its value by
printf("%2X",stemp);
the value is hexadecimal and it is the desired answer
now i want to write this value into file with its hexa format
how is that possible
please urgently help me
emma

You can use sprintf to change the hexadecimal value into a string format and then write it to a file just like any other string. There could be some other way too, but this is what struck me at this moment.

i think sprintf will convert it, others these might be of use to you
just dug them out.
void CharStr2HexStr(unsigned char const* pucCharStr, char* pszHexStr, int nSize)
{
char szHex[3];
pszHexStr[0] = 0;
for(int i=0; i<nSize; i++)
{
Char2Hex(pucCharStr[i], szHex);
strcat(pszHexStr, szHex);
}
}
//unsigned char to str of len 2
void Char2Hex(unsigned char uch, char* szHex)
{
unsigned char byte[2];
byte[0] = uch/16;
byte[1] = uch%16;
for(int i=0; i<2; i++)
{
if(byte[i] >= 0 && byte[i] <= 9)
szHex[i] = '0' + byte[i];
else
szHex[i] = 'A' + byte[i] - 10;
}
szHex[2] = 0;
}
reverse the process
void HexStr2CharStr(char const* pszHexStr, unsigned char* pucCharStr, int nSize)
{
unsigned char uch;
for(int i=0; i < nSize; i++)
{
Hex2Char(pszHexStr+2*i, uch);
pucCharStr[i] = uch;
}
}
//convert str of len 2 to unsigned char
void Hex2Char(char const* szHex, unsigned char& uch)
{
uch = 0;
for(int i=0; i<2; i++)
{
if(*(szHex + i) >='0' && *(szHex + i) <= '9')
uch = (uch << 4) + (*(szHex + i) - '0');
else if(*(szHex + i) >='A' && *(szHex + i) <= 'F')
uch = (uch << 4) + (*(szHex + i) - 'A' + 10);
else
break;
}
}

Hi,
If you want to write it in a Text-File then you can use the answer above or another option.
CString szHex = "";
szHex.Format (_T("%x"), yourVariable); //With little Hexadecimal letters
szHex.Format (_T("%X"), yourVariable); //With capital hexadecimal letters
and then send it to the file as all other strings.
If you want to write it in a Binary-File, I used this in my project.
This from my view:
CFile f (pcFileName, CFile::modeCreate | CFile::modeWrite);
obj.WriteHeader (&f);
dwActualPos = f.SeekToEnd ();
This from the CObject-derived where WriteHeader is:
void obj::WriteHeader (CFile* file)
{ Header[0] = 0x23957112
Header[1] = 0x00001011;
Header[2] = CalculateCodeLarge ();
Header[3] = CalculateDataLarge ();
Header[4] = CalculateNumberOfElements ();
Header[5] = 0x00000000;
Header[6] = (DWORD) GetInputsCount ();
Header[7] = (DWORD) GetOutputsCount ();
Header[8] = 0x00010000;
DWORD* pHeadBuf;
pHeadBuf = &Header[0];
file->Write (pHeadBuf, sizeof (Header));
return;
}
So you can send the hex directly.
