I need to implement a class like a CMyResultSet class. The client code which call CMyResultSet would look like this:

CMyResultSet res;
GetResultSet(res);
for (int i = 0; i < res.rows(); ++i)
{
string res1 = res[i][0].tostring();
}

I have no idea how to implement [][] to let the client code calling like that. How would the method's prototype look like? And How can I save the searched result set in two dimension array, using std::vector or what? Thanks in advance!

I have a MDI winform program, I create a child WinForm frmChild; In this frmChild, I have a button Add to do some operation, after the operation is done, I want to destroy the frmChild form. How can I do this?

OnBtnAdd()
{
do_operation();
//do the operation, and succeeded
//then I want to destroy this child form.
//here How to destroy the child form?
}

Actually, I am doing this, this doesn't work. Maybe some property I've set wrong?

I had a MDI WinForm Program, when click from a menu item, I new a new child WinForm(this child WinForm designed in the designer), but this new child WinForm is not maximumed even I set the childForm.WindowState = System.Windows.Forms.FormWindowState.Maximized; Could you show me how to do this? Thanks in advance!

I have a COM dll, the dll expose a method BOOL Open(const wchar_t* filename, OUT std::vector<MyStruct>& dataout); The function 'Open' take the parameter filename, to open the file, and construct the data from the file to pass it out to outside world. But of course the client crash in runtime because the CRT problem, I googled and the link give me answer, http://social.msdn.microsoft.com/Forums/en-US/vclanguage/thread/83a026d8-09b1-4d57-8c4a-ab2d139624b4[^] So if I don't want pass STL vector as out parameter, then How can I design my COM dll to deal with such situation(open read the file and pass out the data)?

I need implement this function in my program.

I hope I can express the question with my poor english. I wanna write a dialog based program, and let user to set the time and at the given time, execute other programs(the user gives the exe file path). Can give some code hint or source code like this? Or a program in sourceforge having such function issue.

Really thank you. You do me a big favor!

Two thread access a std::list object, either of two will add to/(delete) the std::list. When make critical section or mutex guard, I know can make the std::list safe. But does std::list itself implemented thread-safe? Thanks advanced for helping unlock my mind!

Thanks. It worked! I vote you 5!^_^

I wanna make cursor IDC_HAND when mouse hover in my CMyButton(derived from CButton). In CMyButton I deal with ON_WM_MOUSEMOVE message, see code below:

void CMyButton::OnMouseMove(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default

ASSERT(m\_hWnd);
TRACKMOUSEEVENT tevent;
tevent.cbSize = sizeof(tevent);
tevent.dwHoverTime = 0;
tevent.hwndTrack = m\_hWnd;
tevent.dwFlags = TME\_LEAVE;
\_TrackMouseEvent(&tevent);

SetCursor(LoadCursor(NULL, IDC\_HAND));//I set cursor to IDC\_HAND here, but not work.
CButton::OnMouseMove(nFlags, point);
if (FALSE == m\_bHovered)
{
	m\_bHovered = TRUE;
	this->Invalidate(TRUE);
}

}

Hope I state my problem clearly!

Use CEdit::LineScroll m_ctlEdit.LineScroll (m_ctlEdit.GetLineCount());

Though I don't know how to check whether the workstation is locked or not. But I do know what wrong with your code! 1、LockWorkStation = GetProcAddress(hUser32, "LockWorkStation"); Only return the function pointer of "LockWorkStation".Then you can use this function! 2、LockWorkStation is the function to lock workstation, not to check whether the workstation is locked or not. Do check MSDN! Gurus may answer your question!

Thank you for your reply, I try to Add LVS_EX_DOUBLEBUFFER to the ListCtrl, but the VC6 doesn't know it at all.(And make sure the dialog "Clip Children" set to false) I'm using vc6 under xp sp3, and with flatform sdk for xp sp2[^] installed.(I've download the Windows Server 2003 PSDK February 2003 Edition from MSDN too, but it can't be installed) I've googled, it says define LVS_EX_DOUBLEBUFFER yourself as follow: #define LVS_EX_DOUBLEBUFFER 0x00010000 I did so, and it compiles through, while the flick problem still exists. Wait for your reply!

If remove LVS_EX_GRIDLINES, it works fine. But I need LVS_EX_GRIDLINES extend style. Can't we resolve this? I saw eMule has such problem also! And when run the MSDN sample about ListCtrl, it has such problem too when using xxx.exe.manifest to enable application visual style. But if don't use xxx.exe.manifest to enable application visual style, even we use LVS_EX_GRIDLINES, it then works fine! It's all about visual styles.

I'm using CListCtrl under windows xp2(with visual style on) with vc++6 create a CListCtrl using LVS_REPORT style and set it LVS_EX_GRIDLINES, When the listctrl has more than one page AND use manifest to make the program using visual styles, click the scroll bar to page down、page up, then it has problems, see the picture[^]. but when not using manifest to set the visual styles, Listctrl doesn't has such problems. Any idea to solve this problem?

void CTestgarbageDlg::OnButton1()
{
SHFILEOPSTRUCT shop;
shop.hwnd = this->GetSafeHwnd();
shop.wFunc = FO_COPY;
shop.pFrom = _T("c:\\AUTOEXEC.BAT\0");
shop.pTo = _T("d:\0");
shop.fFlags = FOF_FILESONLY;

int iRet = -1;
iRet = SHFileOperation(&shop);
if (iRet == 0)
{
	//sucess
	AfxMessageBox(\_T("sucess"));
}
else
{
	AfxMessageBox(\_T("fail"));
}

}

I've tried the code above, it works fine. Hope it helps you.

When right click my tray icon, show the menu, And there is a menu item "Restore window". When click this menu item, it should restore window. My code implement "Restore window" below:

void CWinSearchDlg::OnTrayRestoreWnd()
{
DestroyTray();
ShowWindow(SW_SHOW);
if (CWnd::GetActiveWindow() != this)
{
SetActiveWindow();
AfxMessageBox(_T("SetActiveWindow"));
}
else
{
AfxMessageBox(_T("no SetActiveWindow")); //it goes here
}
BOOL bRet = FALSE;
bRet = SetWindowPos(&wndTop, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOMOVE);
if (bRet)
AfxMessageBox(_T("SetWindowPos true"));//it goes here
else
AfxMessageBox(_T("SetWindowPos false"));

bRet = FALSE;
bRet = SetForegroundWindow();
if (bRet)
	AfxMessageBox(\_T("true SetForegroundWindow"));//it goes here
else
	AfxMessageBox(\_T("false SetForegroundWindow"));

bRet = FALSE;
bRet = ::BringWindowToTop(this->GetSafeHwnd());
if (bRet)
	AfxMessageBox(\_T("BringWindowToTop true"));//it goes here
else
	AfxMessageBox(\_T("BringWindowToTop false"));

}

I've tried the code in blue font, but when restore the window, It doesn't bring to the top. Please give me a sign!
