Hi all,
My app needs to destroy a shortcut on the desktop (located in "AllUsers", running on Windows XP). Since the users are not administrators, I use the following code to connect with a dedicated admin account. The (existing) link to delete is "bcFile".
This code works fine with an administrator account and return with no error for normal users. In the later, the shortcut diseapear from the destop only to reappear when the end user press F5. I personnaly guess for a problem in the quotation marks from wCommand or wParams.
PROCESS_INFORMATION pi;
AnsiString sCommand = "C:\\windows\\system32\\cmd.exe";
int iBuffSize = sCommand.WideCharBufSize();
wchar_t* wCommand = new wchar_t[iBuffSize];
wCommand[0] = 0;
sCommand.WideChar(wCommand, iBuffSize);
AnsiString sParams = " del \"/C \"" + bcFile + "\"\" ";
wchar_t wParams[MAX_PATH + 1];
MultiByteToWideChar(CP_ACP, MB_PRECOMPOSED, sParams.c_str(), -1, wParams, MAX_PATH);
AnsiString sUsername = "masteraccount";
AnsiString sDomain = "production";
AnsiString sPassword = "234l2k3j4";
if (CreateProcessWithLogonW(
static_cast<const wchar_t*>(sUsername.data()),
static_cast<const wchar_t*>(sDomain.data()),
static_cast<const wchar_t*>(sPassword.data()),
LOGON_NETCREDENTIALS_ONLY, wCommand,
wParams, 0, NULL, NULL, NULL, &pi) != 0) {
// Notify the shell for delete operation.
SHChangeNotify(SHCNE_DELETE, SHCNF_PATH, bcFile.c_str(), NULL);
}
else {
CustomErrorHandler(ERR_ABORT, ERR_DEL_SHORTCUT);
}
Any help on this or another way to do the shortcut delete will be appreciated.

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);
