This below event handler belongs to ADD button of main dialogue
void CNewUiDlg::OnBnClickedAdd()
{
CPhoneBook m_ph(this);
CString val;
int mark=m_mainlist.GetSelectionMark();
m_checken=m_mainlist.GetItemText(mark,0);
//m_ph.AddtoPB(m_checken);
}
This below function belongs to class that is controling tab pane
BOOL CPhoneBook::AddtoPB(CString s)
{
m_phoneval=s;
m_listphone.InsertItem(0,m_phoneval);
m_listphone.SetItemText(0,1,m_address);
UpdateData(false);
//MessageBox(m_phoneval); the message box displays the string
}
Instead if we add an ADD button to the tabpane itself and add the handler as below it works and displays the contents from list control of main dialogue to list control of tabpane
void CPhoneBook::OnBnClickedAdd()
{
m_listphone.InsertItem(0,m_checken);
m_listphone.SetItemText(0,1,m_address);
}

you should not use GetSelectionMark() to get the selected item. Use GetNextItem instead. Also give show selection always style to list control and check. Let me know the result after this modification.

Hello everybody,
I'm trying to port old apps to the new system (the express version), just before buying the new VC8 software.
I've found this: in the old code there is a #include <fstream> clause in one of the implementation files (and it works).
In the new VC8, it appears an error that says: fatal error C1083: Cannot open include file: 'fstream.h': No such file or directory
Any idea on how to solve that?
As always thank you in advance.

You were using a non standard header. The standard headers from the .h, so fstream, not fstream.h, iostream, not iostream.h, etc.
You probably need a using namespace std; as a result.

Hello Comunity,
i need to update and sort a file content, that hava a first line as header?
Is there any function in C++ for that, also i have a multiline file and i want to update the line 5
wit new content!
Lines beginnst always with number that are not sorted!
thanks for any help!
break;

You can't simply add and remove lines from the middle of files. Treat each line line a string, each line like an array and the whole file like an array of strings. If you want to insert a string at index 10 of a sized 20 array, you would need to grow the array and move everything after index 10. This can be a time consuming process.
For the sake of speed, open the file as a memory mapped file and cast it to an array of strings.

there is no direct or random access method.. you have to do that line by line... no alterbative .. if your file is small you can create memory mapped file random update the file in memory!

hi,
Need to create context menu in win32 ,in the list view control when I right click on the listitem .
It will open the popmenu or contextmenu and give the option "Delete".
then it will remove the file from the listview.
|
|
|
|
|
1. overide the NM_RCLICK message of list control.
2. Inside it create a CMenu object and load menu from the resource.
3. Call TrackPopupMenu of the CMenu object.

HMENU hmenuTrackPopup;
POINT pt;
HMENU hMenu=LoadMenu(hInst,TEXT("IDR_MENU1"));
TrackPopupMenu(hmenuTrackPopup,TPM_LEFTALIGN | TPM_RIGHTBUTTON,<code>pt.x, pt.y</code>, 0, hList, NULL);

That point is given to you when the user clicks the mouse. 
|
|
|
|
|
use
CPoint pt = GetCurrentMessage()->pt;
nave
|
|
|
|

Catch WM_CONTEXTMENU, it gives you the mouse location as well.
Load the menu you want to show (usually load menu from resource id, then load sub menu).
Call TrackPopupMenu.

Thank you all nice guys!
but still the application is not give me the "delete" popup/context menu.
the code is below.
if(((LPNMHDR)lParam)->code == NM_RCLICK)
{
HMENU hmenuTrackPopup; // shortcut menu
POINT pt;
GetCursorPos(&pt);
HMENU hMenu=LoadMenu(hInst,TEXT("IDR_MENU1"));
hmenuTrackPopup= GetSubMenu(hMenu, 0);
TrackPopupMenu(hmenuTrackPopup,TPM_LEFTALIGN | TPM_RIGHTBUTTON,pt.x,pt.y,0, hList, NULL);
}

i doubt the way you created the context menu in the resource. U must create the Delete menu as submenu.
eg:
Mainmenu
|
|->Delete
then u must specify the id of main menu in the LoadMenu() function
more over if u use CMenu, it will be a little easiler that the above
CMenu PopUpMenu;<br />
PopUpMenu.LoadMenu( IDR_MENU1 );<br />
CPoint pt;<br />
pt = GetCurrentMessage()->pt;<br />
PopUpMenu.GetSubMenu( 0 )->TrackPopupMenu( TPM_LEFTALIGN, pt.x, pt.y, this, 0 );

which includes are necessary for CMenu because i am not working on MFC.
i have replace POINT with CPoint.but how menu ???
Amit

no pblm ...use sdk calls it self
POINT pt;
HMENU hMenu=LoadMenu(hInst,TEXT("IDR_MENU1"));
Point pt;
pt = GetCurrentMessage()->pt;
HMENU hSubmenu = GetSubMenu( hMenu,0 );
TrackPopupMenu( hSubmenu, TPM_LEFTALIGN, pt.x, pt.y, hList, 0 );
but dont forget to make the delete as submenu.
i found another ppblm in your code
HMENU hMenu=LoadMenu(hInst,TEXT("IDR_MENU1"));
TrackPopupMenu(hmenuTrackPopup,TPM_LEFTALIGN | TPM_RIGHTBUTTON,pt.x, pt.y, 0, hList, NULL);
in the above code that you pasted earlier, you r loading the menu to hMenu. But your calling the TrackPopupMenu with handle hmenuTrackPopup

hi nave ,
ask you one question how can i handle an event for the delete button
for that i have put my code in
<br />
case WM_COMMAND:<br />
<br />
switch(LOWORD(wParam))<br />
{ <br />
case ID_DELETE_DELETE: <br />
{<br />
int iSlected=0;<br />
iSlected=SendMessage(hList,LVM_GETNEXTITEM,-1,LVNI_FOCUSED);<br />
if(iSlected==-1)<br />
{<br />
MessageBox(hList,_T("No Items in ListView"),_T("Error"),MB_OK|MB_ICONINFORMATION);<br />
break;<br />
} <br />
ListView_DeleteItem(hList,iSlected); <br />
}<br />
<br />
break;<br />
<br />
}<br />
<br />
should it work or now i have to write somewhere else?
