I'm quiet a beginner and it's kind of difficult to discribe my problem. Let's try. I'm programming a SDI application, with the possibilty to run this programm on the console. Now my question: How can i output text to the console? I've already tried WriteConsole, but this seems to work only if you allocate a new console. But i want to write to the console i'm starting the programm from. Can anyone give me a hint?

Yes, you're right, you need to create a console for output if you're using WriteConsole().

If you want to output it to the caller's console, then you need to create the output console HANDLE in the caller, starting program, thread, fibre, whatever, and pass the output console HANDLE to whatever you're trying start up (How you do that is up to you - commandline args, thread args - etc, etc). Then you should be able to use WriteConsole() using the handle passed to it.

Now, if I may comment.

The reason that SDI, MDI, and any other windowing programmes exist is that they expect user input, even if it is only a mouse click, or there are special circumstances for output - just have a look at all the processes running on your computer - guaranteed that most are background tasks with no user interface or the user interface is mediated by a second programme.

If you want to write a 'console' programme then you don't need all the baggage that comes with windowing.
If you want to write a programme that needs even moderately complicated user interaction, then think about the model you're using.

Thanks first! I'll try to follow your advice with the handle.

The reason for using a SDI is, that in the end there shall be a programm, that can be run either in console mode by passing the parameters directly or in GUI mode, when there are no parameters given in the command line. But i'm just beginning this project.

#include <iostream><br />
<br />
then cout << ... << endl;

???

just a guess, hope it helps.

If tried that, but it doesn't seem to work with SDI. Thanks anyway.

Horizental Scroll is not Appearing in CCheckListBox .. Urgent

31-Jan-05 21:38

I've managed the problem by changing the linker settings.

- from /subsystem:windows to /subsystem:console (Project - Settings - Link - Project Options edit box)
- WinMainCRTStartup as Entry-point symbol (Project - Settings - Link - Output - Entry-point symbol).

Now it's possible to use printf as well as WriteConsole.

Smile | :)

HI
I am Creating ChecklistBox it shows Vertical Scroll Bar but not Horizental why ? I am using Horizental Scroll bar style.
Reply me urgent

Code is below

int CChkListDlg::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CDialog::OnCreate(lpCreateStruct) == -1)
return -1;

// TODO: Add your specialized creation code here
DWORD dwStyle = WS_CHILD | WS_BORDER | WS_VISIBLE | WS_VSCROLL|
WS_HSCROLL | LBS_HASSTRINGS | LBS_NOTIFY;

// Abov style has Horiztl and Vertcl Scroll Style

CRect rcDlg;
GetWindowRect(&rcDlg);
ScreenToClient(&rcDlg);

int L = (int)( 7.0 * rcDlg.Width() / 157.0);
int T = (int)( 19.0 * rcDlg.Height() / 167.0);
int R = (int)( 148.0 * rcDlg.Width() / 157.0);
int B = (int)( 118.0 * rcDlg.Height() / 167.0);
CRect ReqRect(L, T, R, B);
m_ChkListBox.Create(dwStyle, ReqRect, this, IDC_CHKFORCEDVAR);

Font.CreatePointFont(8 * 10, "Arial");
m_ChkListBox.SetFont(&Font);

for(int i=0; i<10 ; i++)
{
CString str;
str= " Data ";
m_ChkListBox.AddString(str);
}

return 0;
}

Regards.

my brother,
Listbox initially donot display horizontal scrollbar, we have to call a member function of listbox which sets the actual width internally , when this width is given larger then the width in Listbox::Create the listbox shows horizontal scrollbar
i have used this method but at this time i am not remembring the actual name of the function, you can check docummentation for Listbox

i think name is
SetHorizontalExtent( int );

Note this function takes only one int value , which represents the width.

thanks for the reply
Where i should this Function in coding ?

I tried it . But it is not Working.

code is :

int CRemoveConstraintsDlg::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CDialog::OnCreate(lpCreateStruct) == -1)
return -1;

// TODO: Add your specialized creation code here
DWORD dwStyle = WS_CHILD | WS_BORDER | WS_VISIBLE | WS_HSCROLL |WS_VSCROLL | LBS_HASSTRINGS | LBS_NOTIFY;
CRect rcDlg;
GetWindowRect(&rcDlg);
ScreenToClient(&rcDlg);
int L = (int)(7.0 * rcDlg.Width() / 150.0);
int T = (int)(18.0 * rcDlg.Height() / 168.0);
int R = (int)(141.0 * rcDlg.Width() / 150.0);
int B = (int)(111.0 * rcDlg.Height() / 168.0);

CRect ReqRect(L, T, R, B);
m_ConsChkListBox.Create(dwStyle, ReqRect, this, IDC_CONSTRAINTS);
if(!AddConstraints())
return -1;
return 0;
}

bool CRemoveConstraintsDlg::AddConstraints()
{
/*for(i=0; i<m_conschklistbox.getcount(); i++)

="" textmetric="" tm;
="" int="" dx="0" ;
="" cdc*="" pdc="m_ConsChkListBox.GetDC();

" pdc-="">GetTextMetrics(&tm);

CStringArray* pList = m_pEdoData->GetpConstraintExpList();
for(int i=0; i<plist->GetSize(); i++)
{
m_ConsChkListBox.GetText(i, str);
sz = pDC->GetTextExtent(str);

m_ConsChkListBox.AddString(pList->GetAt(i));
sz.cx += tm.tmAveCharWidth;

if (sz.cx > dx)
dx = sz.cx;

}

m_ConsChkListBox.ReleaseDC(pDC);

// Set the horizontal extent so every character of all strings
// can be scrolled to.
m_ConsChkListBox.SetHorizontalExtent(dx);

return true;
}

waitng for ut reply
thanx

You have to set the show Horizontal Toolbar and implement a function like following:
call it when you have added the items...

good luck.

PS: Although probably not intended, your mail almost seems unpolite. Don't sweat it, It won't keep me up at night Smile | :)

, but try to take care of your language. Big Grin | :-D

void DlgFlexListSelectValue::SetHorizontalScrollBar(){<br />
	//Next is to set the horizontal scroll bar<br />
	//Find the longest string in the list box.<br />
	CString str;<br />
	CSize sz;<br />
	int dx = 0;<br />
	TEXTMETRIC tm;<br />
	CDC* pDC = m_valueList.GetDC();<br />
	CFont* pFont = m_valueList.GetFont();<br />
<br />
	//Select the listbox font, save the old font<br />
	CFont* pOldFont = pDC->SelectObject(pFont);<br />
	//Get the text metrics for avg char width<br />
	pDC->GetTextMetrics(&tm); <br />
<br />
	for(int i = 0; i < m_valueList.GetCount(); i++){<br />
		m_valueList.GetText(i, str);<br />
		sz = pDC->GetTextExtent(str);<br />
<br />
		//Add the avg width to prevent clipping<br />
		sz.cx += tm.tmAveCharWidth;<br />
<br />
		if(sz.cx > dx){<br />
			dx = sz.cx;<br />
		}											//end if<br />
	}												//end for<br />
<br />
	//Select the old font back into the DC<br />

I just posted the reply? How could you have tried so fast?

Anyway, it's working in my code, I faced the same problem and looked on MSDN where I (for once) found the reply (complete with examplecode)

I'd suggest you take a look there, there's nothing more I can do for you. sorry.

is it?

thanx

SetHorizontalExtent()
works both for listbox and check listbox

I have used it in checklistbox in one project where it worked OK

Please use SetHorizontalExtent() before AddString()
you can use any value suppose 100 or 200
then try , I think it will work

It works but After Addstring()
