Hi,
Due to the tremedeous replies, I finally worked it out myself.
So forget about the CreateProcess stuff.
I now use "CreateThread", in which I call "LogonUser".
Works fine. Simplier. No dependencies to "cmd.exe".

I have an SDI application. This SDI application has a Splitter control, which has Pane controls and the pane controls themselves have other child controls. So, there is a hierarchy of controls. Now, If I have the handle of any child control, I want to get the Handle of the SDI application window. Is there any way to achieve this?
GetParent() may work, but I would certainly not know how many GetParent()s I am supposed to call. For Example, if I have the HWND of the PaneControl, I would have to call GetParent() twice. One for the Splitter control and the other for the application Window. Similarly, if I have the handle of the Splitter control, I would have to call GetParent() only once. This is the why I think GetParent() is not such a good idea. Any other options?

use AfxGetMainWnd type cast the return window to your derived FrameWnd Class

Thanks. What if I am not using MFC and using the Win32 API?

Try AfxGetMainWnd()
From MSDN:
If AfxGetMainWnd is called from the application's primary thread, it returns the application's main window according to the above rules. If the function is called from a secondary thread in the application, the function returns the main window associated with the thread that made the call.

Would this suffice:-
CWnd* AFXAPI AfxGetMainWnd( );

hello
I am trying to make a list control , so that it will display both name and
number when i enter them.
1) how do i delete an item from the list control
ie
void CSpeedDial::OnSpeedDel()
{
//
}
2)how do i move an item up or down in the list contol using "up buttom" and
"down buttom" i have created
ie
void CSpeedDial::OnSpeedUp()
{
}
and
void CSpeedDial::OnSpeedDown()
{
}
3)how do i make the "add buttom" disable when i have 8 items in the list
control.
this is what I have done so far:
BOOL CSpeedDial::OnInitDialog()
{
CDialog::OnInitDialog();
CRect rect;
m_speedList.GetClientRect(&rect);
m_speedList.InsertColumn(0,_T("Name"),LVCFMT_LEFT,rect.Width()/2,0);
m_speedList.InsertColumn(1,_T("Number"),LVCFMT_LEFT,rect.Width()/2,0);
m_speedList.SetImageList(&imList, LVSIL_SMALL);
for (int i=0;i< m_speedArray.GetSize();i++)
{
m_speedList.InsertItem(i,m_speedArray.GetAt(i));
}
// TODO: Add extra initialization here
return TRUE; // return TRUE unless you set the focus to a control
// EXCEPTION: OCX Property Pages should return FALSE
}
void CSpeedDial::OnSpeedAdd()
{
// TODO: Add your control notification handler code here
CString AliasName,AliasNumber;
m_speedName.GetWindowText(AliasName);
m_speedNumber.GetWindowText(AliasNumber);
AliasName.TrimRight();
AliasName.TrimLeft();
AliasNumber.TrimLeft();
AliasNumber.TrimRight();
if(AliasName.FindOneOf("=|")>=0) return;
int nIndex = m_speedList.InsertItem(m_speedList.GetItemCount(),AliasName);
m_speedList.SetItemText(nIndex,1,AliasNumber);
m_speedName.SetWindowText(_T(""));
m_speedNumber.SetWindowText(_T(""));
}
thanks for you help

You can decide it, on PretraslateMessage, or WM_KEYDOWN message.

i did sth like this but it is not working
void CSpeedDial::OnSpeedDelete()
{
POSITION pos = m_speedList.GetFirstSelectedItemPosition();
if(pos == NULL) return;
int index = m_speedList.GetNextSelectedItem(pos);
if(index<0 || index>m_speedList.GetItemCount()||
m_speedList.GetItemCount()!= m_speedArray.GetSize())
return;
m_speedList.DeleteItem(index);
m_speedArray.RemoveAt(index);

}

So what's not working with it? You've got a lot of code there that needs to be narrowed down to just a single statement or two. Set breakpoints. Use the debugger. Step into the code to see what is going on.
The first thing to try is this:
void CSpeedDial::OnSpeedDelete()
{
m_speedList.DeleteItem(0);
}If this works, then you know what the problem is not.

i just removed some of the lines from the code
void CSpeedDial::OnSpeedDelete()
{
POSITION pos = m_speedList.GetFirstSelectedItemPosition();
int index = m_speedList.GetNextSelectedItem(pos);
m_speedList.DeleteItem(index);
// TODO: Add your control notification handler code here
}
but how can i move an item up and down in the list
i am a beginner

Which can be shortened to:
void CSpeedDial::OnSpeedDelete()
{
int index = m_speedList.GetNextItem(-1, LVIS_SELECTED);
if (index != -1)
m_speedList.DeleteItem(index);

thanks, that code is really short and simple.
I tried moving a selected item up in the list control, but it is not working.
what may wrong with the code
void CTestingDlg::OnUp()
{
int index = m_cListCtrl.GetNextItem(-1, LVIS_SELECTED);
m_cListCtrl.InsertItem(index -1, m_cListCtrl.GetItemText(index, index));
m_cListCtrl.DeleteItem(index +1);

}

deleting it first, deletes the row as i click on the buttom
i extracted my code from here.
BOOL CListCtrlEx::MoveRow(int from, int to)
{
//Can't move to the same place, or from or to a negative index
if(from == to || from < 0 || to < 0)
return FALSE;
//First Copy the row to the new location
if(CopyRow(from, to))
{
//If we have just inserted a row before
//this one in the list, we need to increment
//our index.
if(from > to)
DeleteItem(from + 1);
else
DeleteItem(from);
return TRUE;
}
else
return FALSE;
}
BOOL CListCtrlEx::CopyRow(int from, int to)
{
//Can't move to the same place, or from or to a negative index
if(from == to || from < 0 || to < 0)
return FALSE;
//Copy the row to the new index
InsertItem(to, GetItemText(from, 0));
//If row has been inserted before original
//increment the original
if(from > to)
from++;
//Loop through subitems
for(int i = 1; i < GetColumnCount(); i++)
{
SetItemText(to, i, GetItemText(from, i));
}
return TRUE;
}

It's not a good idea to copy code from elsewhere unless you have a good understanding of what it is doing. If the code is doing a specific task and you copy it to a new location, its role will change.
void OnClickMoveUp( void )
{
int nIndex;
CString strCommand;
nIndex = m_listctrl.GetNextItem(-1, LVNI_SELECTED);
ASSERT(-1 != nIndex);
strCommand = m_listctrl.GetItemText(nIndex, 0);
m_listctrl.DeleteItem(nIndex);
nIndex = m_listctrl.InsertItem(nIndex - 1, strCommand);
}

thanks, it works perfectly with a list with only one column, what about if you have 2 columns

jokefake wrote: it works perfectly with a list with only one column, what about if you have 2 columns
Multiple calls to GetItemText(), for starters.

i did sth like this and the result was no good at all
void CTestingDlg::OnUp()
{
int nIndex;
CString strCommand,strCommand2;
nIndex = m_cListCtrl.GetNextItem(-1, LVNI_SELECTED);
ASSERT(-1 != nIndex);
strCommand = m_cListCtrl.GetItemText(nIndex, 0);
strCommand2 = m_cListCtrl.GetItemText(0,nIndex);
m_cListCtrl.DeleteItem(nIndex);
nIndex = m_cListCtrl.InsertItem(nIndex - 1, strCommand);
m_cListCtrl.SetItemText(nIndex-1,1, strCommand2);
}

|

jokefake wrote: strCommand2 = m_cListCtrl.GetItemText(0,nIndex);
Should be:
strCommand2 = m_cListCtrl.GetItemText(nIndex, 1);
