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?

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

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 );

Print a CString

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 object attached to "prn:"<br />
filebuf fb( "prn:" ); // Filebuf object attached to "prn:"<br />
cout = &fb; // fb associated with cout<br />
cout << "testing"; // Text goes to PRN: not stdout

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

An easy way is to use GetPrinterDC on a CPrintDialog, use StartDoc to begin a new print job, use TextOut to print your CString (you will have to split it...). Use EndPage to end each page you create, and EndDoc to start printing. You have an example at:

But if i create an project in VC.Net, can I open it in VC6.0. WTF | :WTF:

Could i know in which file the version is serialized.

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

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

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:

//Creation of the file, with overwriting if name matches
CFile f (pcFileName, CFile::modeCreate | CFile::modeWrite);
	
//Writing the PCode itself
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.
