Hi all,
How can I force the user to select only via dropdown, but not allowing him to edit in combobox?
Thanks,
Sunil.

Change the combobox style to CBS_DROPDOWNLIST[^]. You can change this in the resource editor. Look at the properties pane, and change the style selection.
|
|
|
|
|
open combo box properties and change style type to DropList
|
|

Thanks a lot,
The problem is solved.

If you want someone to even try to look at your code, read the posting guidelines at the top of the forum, They're there for a good reason.
Hint: pre tag.
Also, choosing an actual name, rather than a number helps.
Lastly, a bit more of a question please! What have you tried? Etc. Have you looked for CP articles that may help? Examples on MSDN? etc.
Iain.
Plz sir... CPallini CPallini abuz drugz, plz plz help urgent.

Thanks in advance.

UINT uFlags = 0;
HTREEITEM hItem = tc.HitTest(point, &uFlags);
if(!hItem)
return;
tc.SelectItem(hItem);
tc.SetFocus();
CString Previous_File;
CString Tree_str = tc.GetItemText(hItem);

Handle WM_KEYDOWN message and inside the message check the key pressed is enter.
void CMyTree::OnKeyDown( UINT nChar, UINT nRepCnt, UINT nFlags )
{
if( nChar == VK_RETURN )
{
}

You can use of CTreeCtrl::GetItemText for get string of an item.
|
|
|
|
|
this is right syntax;
CString GetItemText( HTREEITEM hItem ) ;
how can i enter HTREEITEM hItem ,on enter the key,

Did you see MSDN see an example of MSDN:
HTREEITEM hCurSel = m_TreeCtrl.GetNextItem(TVI_ROOT, TVGN_CARET);
// report it to the user
if (hCurSel == NULL)
{
AfxMessageBox(_T("There is no selected item"));
}
else
{
CString str;
str.Format(_T("The currently selected item is \"%s\""),
(LPCTSTR)m_TreeCtrl.GetItemText(hCurSel));
AfxMessageBox((LPCTSTR)str);
}

Thanks now it is working.

Given a stack S and a queue Q, write a program in OOP (C++)that have 2 procedures FILLQ_WITHS will empty the contents of the stack S and insert them into the Queue Q and FillS_WithQ which will fill the stack S with the elements deleted from the queue Q. Impliment the procedure with S and having an array representation.
plz do this as soon as possible

You can write your program and ask of us your problem but you wrote your question and then you said "plz do this as soon as possible".
please read "How to get an answer to your question " first post at this forum.
