Hi,
That'll work! I think I'll implement the CreateClone(...) methods as you suggest.
A shame that standard C++ won't let you explicitly override a specific base class's pure virtual, but that's life I guess. I'm sure there's a good (and suitably obscure) reason for it.
Cheers,
Pete

Hello,
I'm making a dialog-based application and I want to assign a CEdit class to an Edit Box and when I right-click on the control and choose "Add Variable...", I can't assign a control variable because the "Control Variable" checkbox is disabled as well as all the control-related parameters. I can add an "int" or "char" or another standard type but I connot add a control variable. Does anyone would know why I can't assign a control variable to my Edit Box??
Thanks in advance,
Veronique

Is this with Visual Studio v6? If so, I'm not seeing the same thing you are (e.g., where do you right-click on the control).

It is with Visual Studio .NET (v7).

Are you positive you don't already have a CEdit member variable for that control?

Hi!
Yes, I'm positive I don't have a CEdit member variable for that control... but now I found the problem. The problem is (was) in the .vcproj project file. In the <Globals> section, the RESOURCE_FILE Value was set to the wrong .rc file. I was trying to assign a member variable to a control that wasn't defined in the specified .rc file. I set the correct .rc file in the .vcproj file and now I can do what I wanted to do.
Here is the <Globals> section of the .vcproj file.
<Globals>
<Global
Name="RESOURCE_FILE"
Value="WX.rc"/>
</Globals>
Thank you all for trying to help me!!
Bye!

Hello Veronique,
It is not hard to do it by hand as well.
- Add the control variable to your dialog header file(
CEdit m_myEdit;) - On your implementation file, add a line to the DoDataExchange method (
DDX_Control(pDX, IDC_MY_EDIT, m_myEdit);, where IDC_MY_EDIT is the ID of the Edit Box) - On your code now you can use the m_myEdit for controlling the edit box. (
m_myEdit.SetWindowText("bla bla bla");)
Hope this helps.

Ok, I'm trying to take this code apart and understand it
http://www.codeproject.com/threads/killprocess.asp
The code is at the bottom.
Now with the TerminateProcess function
bResult = TerminateProcess(hProcess,0);
What are the parameters that it takes, is 0 the PID?
Thanks

0 is the exit code.

What other exit codes are there,
and with the first argument for the terminate process function.
I tired the code and for this segment
HANDLE hProcess = FindProcess(pstrProcessName,
dwId);
I get a compiling error saying it can't find the function FindProcess.
This is going to show how little I know about windows coding but what is a HANDLE?
Thankss

Exit codes are application specific, with 0 usually indicating success.

I cannot find it in MSDN. Do you know it to exist?

FindProcess() is a private method of the CKillProcess class. It can only be used within a CKillProcess object.

You referenced an article by Eugene Polonsky. The source code is in that article.

Hello,
I have a CFormView in which i have a tabcontrol with two tabs and there are two dialog boxes which act as the pages for the tabs. Inside these dialog boxes i have added a CListCtrl which i would like to populate with data. These two dialog boxes have their own classes and I have added a variable to each of these dialog boxes pointing to the CListCtrl. However when i want to use this variable inside the Dialog class to populate the CListCtrl I notice that the CListCtrl hWnd = 0x00000000. I think this is the problem and does anyone know how to fix it?
thanks,
Lino

Do you have an entry for the list control in the dialog's DoDataExchange() method? At what point are you trying to populate the list control?

here it is:
the base code for this is from something published by Ben Hill on CTabCtrl applications.
//*View.h
CMyTabCtrl m_tabMyTabCtrl;
In OnInitialUpdate in my *View.cpp
void CTestTabCtrlThreeView::OnInitialUpdate()
{
CFormView::OnInitialUpdate();
GetParentFrame()->RecalcLayout();
ResizeParentToFit();
m_tabMyTabCtrl.InsertItem(0, _T("Tab One"));
m_tabMyTabCtrl.InsertItem(1, _T("Tab Two"));
m_tabMyTabCtrl.Init();
}
//Init is a member function of the CMyTabCtrl Class
void CMyTabCtrl::Init(void)
{
m_tabCurrent=0;
m_tabPages[0]->Create(IDD_TAB_ONE, this);
m_tabPages[1]->Create(IDD_TAB_TWO, this);
m_tabPages[0]->ShowWindow(SW_SHOW);
m_tabPages[1]->ShowWindow(SW_HIDE);
SetRectangle();
}
void CMyTabCtrl::SetRectangle(void)
{
CRect tabRect, itemRect;
int nX, nY, nXc, nYc;
GetClientRect(&tabRect);
GetItemRect(0, &itemRect);
nX=itemRect.left;
nY=itemRect.bottom+1;
nXc=tabRect.right-itemRect.left-1;
nYc=tabRect.bottom-nY-1;
m_tabPages[0]->SetWindowPos(&wndTop, nX, nY, nXc, nYc, SWP_SHOWWINDOW);
for(int nCount=1; nCount < m_nNumberOfPages; nCount++)
{
m_tabPages[nCount]->SetWindowPos(&wndTop, nX, nY, nXc, nYc, SWP_HIDEWINDOW);
}
//below this point is where my code begins
//here i create a tmp object of type CTabOne which is derived from CDialog
CTabOne tmp;
tmp.Populate();
}
//CTabOne is the dialog box created to work with TabOne of the CTabCtrl
//and it has a data member of type CListCtrl m_TabOneList
void CTabOne::Populate(void)
{
CPersonInfo Person;
m_TabOneList.SetExtendedStyle(LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES);
//ListView_SetExtendedListViewStyle(rDest.m_hWnd, LVS_EX_GRIDLINES | LVS_EX_FULLROWSELECT);
//get client rect of list view control
RECT rect;
m_TabOneList.GetClientRect(&rect);
//delete all of the items in teh CListCtrl
//deletes all rows in the CListCtrl before populating
m_TabOneList.DeleteAllItems();
//open CRecordSet
if(Person.IsOpen())
Person.MoveFirst();
else
Person.Open();
//test to see if there are zero columns
if(m_TabOneList.GetHeaderCtrl()->GetItemCount() == 0)
{
//insert column headings
//rDest.InsertColumn(
m_TabOneList.InsertColumn(0, "First", LVCFMT_LEFT, rect.right/2);
m_TabOneList.InsertColumn(1, "Last", LVCFMT_LEFT, rect.right/2);
}
//loop to add rows to listview control
while(Person.IsEOF() == false)
{
//add each row
int row = m_TabOneList.InsertItem(m_TabOneList.GetItemCount(),Person.m_FirstName);
//set next column item
m_TabOneList.SetItemText(row, 1, Person.m_LastName);
//assign the row to an invisible column
m_TabOneList.SetItemData(row, Person.m_ID);
//move to next row
Person.MoveNext();
}
}
void CTabOne::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
DDX_Control(pDX, IDC_LIST1, m_TabOneList);
}
hope this helps.
Thanks for your Help.

So is this a modal or modeless dialog? In either case, it looks as though the list control does not actually exist at the point in which you are attempting to populate it.

Controls on a dialog should not be messed with (e.g., populated, moved, sized, read from) before the dialog's OnInitDialog() method, or after the dialog has been dismissed.
