hi KarstendK, I don't understand what you mean. When I move the mouse over the button, it shows.

I have a button on a list, something like whenever you select a row, move the button to that row. So I implement this in OnLvnItemchangedList event:

void CMyDlg::OnLvnItemchangedList(NMHDR *pNMHDR, LRESULT *pResult)
{
...
// canculate the rec by seleted row
CRect rec;
...

// move button
m_myBtn.MoveWindow(rec);
m_myBtn.ShowWindow(SW_SHOW);
m_myBtn.BringWindowToTop();

InvalidateRect(rec);
m_myBtn.RedrawWindow();

}

It works, but I cannot see the button. :confused::confused: If the mouse moves over the button, it shows then I can see it. I don't know why, maybe there's something wrong in my last two source code rows. Can anyone explain how to solve this?? Thank you in advance !!

maybe the best way is avoid it. It's terrible the way MFC handle an event, :( anyway, thank you very much, Randor!!

does any one have any idea in this case??? help me, please!!!

uhm, I already tried return FALSE, but it's not better. .. I will try this a litter bit later. Thank you very much, David Delaune.

uhm, I'm not sure that ... Is this what you mean:

ON_NOTIFY_REFLECT_EX(LVN_ITEMCHANGED, &CMyListCtrl::OnLvnItemchanged)

BOOL CMyListCtrl::OnLvnItemchanged(NMHDR *pNMHDR, LRESULT *pResult)
{
// TODO: Add your control notification handler code here
LPNMLISTVIEW pNMLV = reinterpret_cast(pNMHDR);
*pResult = 0;
....
return TRUE;
}

I cannot see any change ..... :(

I create a List ctrl derivered from CListCtrl. In this class, I implement item changed event

class CMyListCtrl :
public CListCtrl

....
BEGIN_MESSAGE_MAP(CMyListCtrl, CListCtrl)
ON_NOTIFY_REFLECT(LVN_ITEMCHANGED, &CTrendListCtrl::OnLvnItemchanged)
END_MESSAGE_MAP()

......
void CMyListCtrl::OnLvnItemchanged(NMHDR *pNMHDR, LRESULT *pResult) // (1)
{
..
}

Then, on my dialog, there's a CMyListCtrl object, like this

CMyListCtrl m_lst;

afx_msg void OnLvnItemchangedList(NMHDR *pNMHDR, LRESULT *pResult);

I try to implement the item changed on that list.

BEGIN_MESSAGE_MAP(CMyDlg, CDialog)
ON_NOTIFY(LVN_ITEMCHANGED, IDC_LIST_GROUP, &CMyDlg::OnLvnItemchangedList)
END_MESSAGE_MAP()

void CMyDlg::OnLvnItemchangedList(NMHDR *pNMHDR, LRESULT *pResult) // (2)
{
...
}

The problem is, if I implement (1), then it doesn't run (2). And if I doesn't implement (1), it can run (2). Actually I want to run both (1) and (2). What should I do in this case? Thank you very much, bro.

I will try them now. At least the option 2 works There 're many functions similar to each other. It's so messy, and not easy to understand .... :( Thank you, Naveen.

nice!! If we use "Use Multi-Byte Character Set", it should be "%s". Or if we use "Use Unicode Character Set", it should be "%S". Thank you, Cedric!!

Thank you, Cedric. I just change the Character Set property to "Use Multi-Byte Character Set" and it's ok now

yes, Cedric. It's a Unicode project. In Project properties, The Character Set is "Use Unicode Character Set" is that wrong?

hi, I have a sql in my program. What I want is exactly like this:

select *
from tbl t
where t.name like '%xyz%'

So in source code, I create sql like this:

CString name = "xyz";
::sprintf_s(szQuery, " select * from tbl t where t.name like '%%%s%%' ", name);

Here is szQuery when I execute

select *
from tbl t
where t.name like '%x%'

Just the first character is printed into szQuery. What's wrong here? what should I do?? Thank you in advance.

Thank you, Nelek. I will try it now!

help me, pleasee!!!

ABOVE_NORMAL_PRIORITY_CLASS 0x00008000
BELOW_NORMAL_PRIORITY_CLASS 0x00004000
HIGH_PRIORITY_CLASS 0x00000080
IDLE_PRIORITY_CLASS 0x00000040
NORMAL_PRIORITY_CLASS 0x00000020
REALTIME_PRIORITY_CLASS 0x00000100

There're some values for priority like above, you can try it!

I try to print a window, using this article: http://support.microsoft.com/kb/186736 It works, but I want to user default printer with landscape. So I try to modify the GetPrinterDC(), like this:

HDC CLogACTsPrintHelper::GetPrinterDC(void)
{
CWaitCursor wait;
PRINTDLG pdlg;
memset( &pdlg, 0, sizeof(PRINTDLG));
pdlg.lStructSize = sizeof(PRINTDLG);

// use default printer
pdlg.Flags = PD_RETURNDEFAULT | PD_RETURNDC;

// set landscape
AfxGetApp()->GetPrinterDeviceDefaults(&pdlg);
DEVMODE* lpDevMode = (DEVMODE*)::GlobalLock(pdlg.hDevMode);
lpDevMode->dmOrientation = (short)DMORIENT_LANDSCAPE;
::ResetDC(pdlg.hDC,lpDevMode);
::GlobalUnlock(pdlg.hDevMode);
// end set landscape

PrintDlg( &pdlg );      


return pdlg.hDC;

}

But I don't know why it return NULL??? If I comment all source code in set landscape block, it works. Or if I do not use default printer and set landscape, it work

// do not use default printer
pdlg.Flags = PD_RETURNDC;
// set landscape
...

Can anyone explain me what's wrong here? Thank you in advance, :)

thank you for your reply! my printer is HP LaserJet 3052, with 1200dpi. So do you have any idea what I should do in this case?

sorry all, I tried to use another solution: codejock software. it's ok now, thank you friends!

I have a MDI project, now I want to print the interface. So I saw this article: http://support.microsoft.com/kb/q186736/ Then I try to apply to my project, just create a menu item or button, do like this:

// message map
ON_COMMAND(ID_PRINT_PRINTALL, &CMyDlg::PrintGUI)

// declare function
afx_msg void PrintGUI();

// implement function
void CMyDlg::PrintGUI(){
// get the Main window
CWnd* a = AfxGetMainWnd();

    // print it, this function is implemented follow the above article
PrintWindowToDC(\*a);

}

But when I run, nothing happen. Have anyone ever tried the similar thing? Please helpppppppp !!!!!!!!!!

I want to print some icons. Here is my code:

CDC* m_PrintDC;
// attach m_PrintDC with printer success .....

CPoint point(10, 10);
HICON aIcon = AfxGetApp()->LoadIcon(IDI_ICON_CHECKEDBOX);
m_PrintDC->DrawIcon(point, aIcon);

//m_PrintDC->DrawText("xxxxxxxxx", &aRect,DT_SINGLELINE | DT_LEFT);

Here IDI_ICON_CHECKEDBOX is a icon ID that I draw. But it doesn't work, I don't know why?? I can print some text with DrawText(...). Anyone know what's wrong here? Thank you in advance.
