Hi,
You do the following,
m_LCtrlPtr->DeleteItem(m_LCtrlPtr->GetSelectionMark());

This will delete the currently selected item in the list control.

GetSelectionMark() is to retrieve the currently selected item.

hope this helps!!

How to select the entire row in CListControl

Hi,
if you need to find the selected item in a listcontrol, there is no function, to do it.

In your code for deleting a row you may use this to find the desired index

	<br />
  long lx;<br />
  LV_ITEM lvItem;<br />
  lvItem.iItem     = 0;<br />
  lvItem.iSubItem  = 0;<br />
  lvItem.mask      = 0;<br />
  lvItem.state     = 0;<br />
  lvItem.stateMask = 0;<br />
<br />
  if(m_VarForListCtrl.GetSelectedCount() != 1 ) return;<br />
  // if none or more than one are selected bail out<br />
<br />
  int  iItem = m_VarForListCtrl.GetTopIndex();<br />
  int  iMax  = m_VarForListCtrl.GetCountPerPage();<br />
  for( int i = iItem; i < ( iItem + iMax ); i++)<br />
     { lvItem.iItem     =  i;<br />
       lvItem.iSubItem  =  0;<br />
       lvItem.mask      = LVIF_STATE;<br />
       lvItem.state     = LVIS_SELECTED;<br />
       lvItem.stateMask = LVIS_SELECTED;<br />
       if( !m_VarForListCtrl.GetItem(&lvItem) )<br />
         { return; // if item can't be read, do nothing<br />
         }<br />
       if( lvItem.state ) break;// found item<br />
     }<br />
  if( !lvItem.state ) return; // no item found<br />
  // lvItem.iItem now has the index of the selected row<br />
  m_VarForListCtrl.DeleteItem(lvItem.iItem);<br />

This code wil find only the selected item if it's visible.
You must adapt the code, if you are searching the whole list.

Was it this you were looking for?

DWORD dwstyle = m_myListControl.SendMessage(LVM_GETEXTENDEDLISTVIEWSTYLE,0,0);
dwstyle |= LVS_EX_FULLROWSELECT;
m_myListControl.SendMessage(LVM_SETEXTENDEDLISTVIEWSTYLE, 0, dwstyle);

this is the hard way, but in VC5 it was the only way to get it work properly.

hope it helps

dwStyle |= LVS_EX_FULLROWSELECT;
m_listctrl.SendMessage(LVM_SETEXTENDEDLISTVIEWSTYLE, 0, (LPARAM)dwStyle);

hi:
the issue is solved it should have been like

CButton* pButt=(CButton*)GetDlgItem(IDOK);

DWORD newstyle = ::GetWindowLong(pButt->m_hWnd, GWL_STYLE) | BS_ICON;
::SetWindowLong(pButt->m_hWnd, GWL_STYLE, newstyle);

CWinApp* pApp=AfxGetApp();
HICON hIcon=::LoadIcon(pApp->m_hInstance,MAKEINTRESOURCE(IDI_CLOSE));
if(hIcon==NULL)AfxMessageBox("null icon");
pButt->SetIcon(hIcon);

return bResult; Smile | :)

thanks

Hiya, I have 2 apps, one calling the other with CreateProcess(). How do I hide the second apps MAIN WINDOW when called??

CreateProcess takes a LPSTARTUPINFO lpStartupInfo,
and in it u have a WORD wShowWindow; which u can set to SW_HIDE

if you invoke a console application , there is some flags in CeateProcess API itself.

the 6 th argument dwCreationFlag - put CREATE_NO_WINDOW
will hide the coonsole window.(not applicable for MS_DOS programms).and remember this only valid for WIndows NT/2000/XP Operating systems

there is another method you can follow if u creatw with WinExec() API, the second argument is the window style...just put WS_HIDE Wink | ;)

simple but a little dirty way...;)

OK, thanks. Have done this:

ZeroMemory( &StartupInfo,sizeof(StartupInfo) );

StartupInfo.cb = sizeof( StartupInfo );
StartupInfo.dwFlags = STARTF_USESHOWWINDOW; // Problem line
StartupInfo.wShowWindow = SW_HIDE; // Problem line

if( CreateProcess( lpApplicationName,lpCommandLine,
NULL,NULL,FALSE,0,NULL,NULL,&StartupInfo,&ProcessInfo ))
{
WaitForSingleObject(ProcessInfo.hProcess,INFINITE );

CloseHandle( ProcessInfo.hThread );
CloseHandle( ProcessInfo.hProcess );
}
else
{
AfxMessageBox( "Error - Opening Invoicing" );
return;}

As soon as I put the StartupInfo.dwFlags and StartupInfo.wShowWindow lines, it fails. It leaves a white shape of my dialog I just called and then errors.

Am I putting these in wrong..

Thanks,
