[Resolved]::Sorting Ctime items in a list ctrl??? [modified] - C / C++ / MFC Discussion Boards

This [^] looks promising.

You are correct, Seems to work:

BSTR MyBstr = ::SysAllocStringByteLen(strVar, strSize);
_bstr_t bstrSend(MyBstr, true);

But your string does not contain such. Perhaps you meant something like:

char cArr[] = { '1', '2', '\0', '3', '\0', '4', '5', '\0' };

I want to get the pixel width and height of a string for a particular font.

I have searched the MSDN and i found the function below

public:
SizeF MeasureString(
String^ text,
Font^ font
}

How can i use this function in my VC++ 2005 MFC project?
I have tried to use System::Drawing but failed.

It seems that your question is depends to Managed C++/CLI forum. Wink | ;)

The code you found (as Hamid pointed out) is for managed c++ code, and would be best in the CLI forum.

You message seems to be confused between .net, and mfc. System::Drawing is not in any way related to MFC.

Assuming you're doing MFC, you can select the font into a DC, and use GetTextExtentEx to get dimensions of a string using that font.

You need to specify text, as "i" is usually narrower than "W".

Iain Clarke appears because ^CPallini still cares.

I have a ListCtrl with a set of CTime:

09.45.25
10.44.22
07.49.25

I need to sort these..

also fyi.. i already have a array consisting of these values in m_arrTimes

Have used:

void CEntryDlg::OnColumnClickItemsList(NMHDR* pNMHDR, LRESULT* pResult) <br />
{<br />
	m_bSortNameAscSpItem = !m_bSortNameAscSpItem;<br />
<br />
	SortingItemsList();<br />
	<br />
	*pResult = 0;<br />
}<br />
<br />
void CEntryDlg::SortingItemsList()<br />
{<br />
	m_ctrlTimesList.SortItems(CEntryDlg::CompareSpItem, (DWORD)reinterpret_cast<DWORD>(this));<br />
<br />
	//To rearrange the serial number in asscending order<br />
	for(int i = 0; i < m_ctrlTimesList.GetItemCount(); i++)<br />
	{<br />
		m_ctrlTimesList.SetItemData(i, (LPARAM)i);<br />
	}<br />
}<br />
<br />
int CALLBACK CEntryDlg::CompareSpItem(LPARAM lParam1, LPARAM lParam2, LPARAM lParamSort)<br />
{<br />
	CEntryDlg*pCurrentObj = (CEntryDlg*) lParamSort;<br />
<br />
	CString strTemp1 = pCurrentObj->m_ctrlTimesList.GetItemText(lParam1, 0); <br />
	CString strTemp2 = pCurrentObj->m_ctrlTimesList.GetItemText(lParam2, 0);  <br />
<br />
	CString strHr1,strMn1,strSc1;<br />
	strHr1 = strTemp1.Mid(0,2);<br />
	strMn1 = strTemp1.Mid(3,2);<br />
	strSc1 = strTemp1.Mid(6);<br />
<br />
	CString strHr2,strMn2,strSc2;<br />
	strHr2 = strTemp2.Mid(0,2);<br />
	strMn2 = strTemp2.Mid(3,2);<br />
	strSc2 = strTemp2.Mid(6);<br />
<br />
	CTime time1(2000,1,1, GetIntFromString(strHr1), GetIntFromString(strMn1),GetIntFromString(strSc1));<br />
	CTime time2(2000,1,1, GetIntFromString(strHr2), GetIntFromString(strMn2),GetIntFromString(strSc2));<br />
<br />
	if(pCurrentObj->m_bSortNameAscSpItem)<br />
	{<br />
		if(time1 == time2)<br />
			return 0;<br />
		else if(time1 < time2)<br />

			return 1;<br />
	}<br />
<br />
	return 0;<br />
}<br />
<br />
CEntryDlg::GetIntFromString(CString str){<br />

			_tcscpy(lpsz, str);<br />
			val=::atoi(lpsz);<br />
			delete[] lpsz;<br />

		return(val);<br />

none of there seem to sort correctly..

I don't know what you are trying to do here (there a lot of missing information to understand your problem and your code). Anyway, if you need to sort CTime objects, you can use the comparison operators[^], that will probably be much better then trying to do it yourself.

thanks.. have implemented that. Still it is not sorting correctly.

Also modified the thread with additional information.

Priya Sundar

By googling a bit (yeah, you can do that too you know Roll eyes | :rolleyes:

), I found this article[^]. Check also the comments.

And this behavior was in fact explained in the documentation[^].

EDIT: by the way, I don't think the solution provided in the article is the correct way to go, but I posted it so that you can see where your problem is. Check some of the comments and you'll find better way to manage it.

Charting control [v1.3]

Hai Cedric,

Actually that article and the links in the article really helped a lot.

And i solved my problem as said in the article - "The function CListCtrl::SortItems(...) is only usefull if we store a pointer in the 32-bit associated value and we want to sort the items by some value that comes from that pointer. "

And I too first google, if i still didnt find the solution, then i post it as a thread.

Then i guess in this case it might help if you suggest me the keywords you used to search this article. That will be a lot of help in future.

Thanks once again!

Priya Sundar

I just used CListCtrl and SortItems. I think I searched on codeproject too (that's why I found the article). So, if you have a problem, you can google for it and search on the CP articles (there is a lot of good stuff here you know Smile | :)

).

Don't forget the developer's best friend: your debugger. Using it in that situation would immediately reveal that there's something wrong with the parameters that are passed to your callback function.

Charting control [v1.3]

Hello All,

I am trying to insert a BMP image in to picture control.

I have added Microsoft common dialog control Ver6 ActiveX control.

IDC_COMMONDIALOG1 Type :- CcommonDialog1 Member:- m_com

Picture Control:-
IDC_STATIC1 Type :- CStatic Member:- m_st1

I have show button in the dialog, when the we click on that we can select a BMP file and show the same file in the Picture control in the dialog.for that i have used the below code.

void CImageAppDlg::OnShow() <br />
{<br />
	// TODO: Add your control notification handler code here<br />
<br />
<br />
<br />
	CString	file;<br />
	file.Empty();<br />
	m_com.ShowOpen();<br />
	file=m_com.GetFileName();<br />
	file.TrimRight();<br />
<br />
<br />
	if(m_hBmpNew != NULL )<br />
		DeleteObject(m_hBmpNew);<br />
	sourcex=sourcey=0;//<br />
	if(file.IsEmpty())<br />
AfxMessageBox("Please Select a picture file");<br />
		else{<br />
			if(file.Right(3)!="bmp")<br />
			AfxMessageBox("Please Select a .bmp file");<br />
			else<br />
			{<br />
	m_hBmpNew =	 (HBITMAP) LoadImage(<br />
	AfxGetInstanceHandle(),  <br />
	file,  <br />
	IMAGE_BITMAP,    <br />
	0,     <br />
	0,    <br />
	LR_LOADFROMFILE); <br />
	if( m_hBmpNew == NULL ){<br />
	AfxMessageBox("Load Image Failed");}<br />
	<br />
   else{<br />
	m_st1.GetClientRect( &rectStaticClient );<br />
	rectStaticClient.NormalizeRect();<br />
	m_size.cx=rectStaticClient.Size().cx;<br />
	m_size.cy=rectStaticClient.Size().cy;<br />
    m_size.cx = rectStaticClient.Width();    // zero based<br />
    m_size.cy = rectStaticClient.Height();    // zero based<br />
<br />
    <br />
  m_st1.ClientToScreen( &rectStaticClient );<br />
  ScreenToClient( &rectStaticClient);<br />
        <br />
    m_pt.x = rectStaticClient.left;<br />
    m_pt.y = rectStaticClient.top;<br />
  GetObject( m_hBmpNew , sizeof(BITMAP), &m_bmInfo );<br />
 VERIFY(m_hBmpOld = (HBITMAP)SelectObject(m_dcMem, m_hBmpNew )  );<br />
<br />
  offsetx= m_pt.x;<br />
  offsety=m_pt.y;<br />
if(m_bmInfo.bmWidth<=m_size.cx)<br />
{<br />
	if((m_size.cx-m_bmInfo.bmWidth)==0)<br />
		offsetx= m_pt.x;<br />
	else<br />
		offsetx= m_pt.x+((m_size.cx-m_bmInfo.bmWidth)/2);<br />
<br />
}<br />
else<br />
if(m_bmInfo.bmHeight<=m_size.cy)<br />
{<br />
	if((m_size.cy-m_bmInfo.bmHeight)==0)<br />
		offsety= m_pt.y;<br />
	else<br />
		offsety= m_pt.y+((m_size.cy-m_bmInfo.bmHeight)/2);<br />
}<br />
else<br />
<br />
  InvalidateRect(&rectStaticClient);<br />
		}<br />
			}<br />
		}<br />
<br />
}<br />

code has no errors but in the run time i am getting this error

Microsoft VC++ Debug Library

Debug Assertion Failed Error

Can u please tell me what is cause for the error ?? Confused | :confused:

Thanking you ...
Pruthvi R.

You can use of LoadImage for load your bmp file or CImage class for other foramats and then use of SetBitmap(HBITMAP).

Hi Hamid,

Thanks for the response.

I have used the LoadImage function only, but still i am getting the run time error. can u please tell me what is the cause.. ?

Can you show your code now :
HBITMAP h=(HBITMAP)LoadImage(...);
m.SetButton(h);
Does your code like this?

Hamid i am unable to understand , can u please have a look at my first post where i have posted my complete code ?? and please let me know what changes i have to make.

Ok run this code did you see any thing on the monitor

//header file
#include "atlImage.h"
CStatic m_Static;

m_Static.Create(NULL,WS_VISIBLE|WS_CHILD|SS_BITMAP,CRect(0,0,100,100),this);
CImage m;
m.Load(_T("d:\\1234.bmp"));
m_Static.SetBitmap(m.Detach());

Does your problem solve?

Hi,

I'm using MFC Visual C++ and encountered a problem using OnKeyDown() function. The problem is that I don't get response from keyboard even if I included all the requirements.

MyDlgClass.cpp
......
......

ON_WM_KEYDOWN
......
......
void CMyDlgClass::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
................
CDialog::OnKeyDown(nChar, nRepCnt, nFlags);

I think, the problem is that the focus wasn't on the dialog but on other objects. If I'm correct how can I possibly shift focus to the dialog or get response from the keyboard?

Hope somebody can help me, thanks.
}

Do you have any controls on the dialog?

Yes, CButtons and CEdit controls.
